  • Medical Resource A List of Unique Alternative Medicine

    Posted on August 2nd, 2009 admin 4 comments

    A list of some of the alternative medicine practices you’re likely to encounter in the United States. Some of these are considered border-line acceptable even in the professional medical field, and many understand that this is unfortunate.
    Mostly these are just scams, quackery, and nonsense, which unfortunately gullible people believe in if they are desperate and grasping at false hope. Keep your eyes peeled for any of these, and be prepared to stamp out the harmful ones.
    Doman-Delacato Treatment
    This approach, also called “patterning,” was developed during the mid-1950s and is still offered at the Institutes for Human Potential in Philadelphia, Pennsylvania. Its proponents claim that the great majority of cases of mental retardation, learning problems, and behavior disorders are caused by brain damage and poor neurological organization. The treatment is based on the idea that high levels of motor or sensory stimulation can train the nervous system and lessen or overcome handicaps caused by brain damage.

    Parents following the program are advised to exercise the child’s limbs repeatedly and use other measures said to increase blood flow to the brain and decrease irritability. In 1982 and 1999, the American Academy of Pediatrics issued position statements concluding that “patterning” has no merit, that its proponents’ claims are false, and that the demands on families are so great that in some cases there may be actual harm in its use. In 1996, neurologist Steven Novella, M.D., reviewed the scientific literature and concluded that “patterning” was a pseudoscience.
    Orthomolecular Therapy
    Orthomolecular therapy is defined by its proponents as the treatment of disease by varying the concentrations of pneumatic cylinder substances normally already present in the human body. Its proponents claim that many diseases are caused by molecular imbalances that are corrected by administration of the “right” nutrient molecules at the right time.
    Orthomolecular therapy dates back at least to the early 1950s when a few psychiatrists began adding massive doses of nutrients to their treatment of many severe mental problems. The original substance was vitamin B3, and the therapy was termed “megavitamin therapy.” Later the treatment regimen was expanded to include other vitamins, minerals, hormones, and dietary supplements, any of which may be combined with conventional drug therapy and even electroshock treatments. A few hundred physicians now use this approach to treat a variety of conditions, both of a mental and physical aspect.
    Raw Milk
    Raw milk is milk in its unpasteurized state. Public health authorities advocate pasteurization to destroy all disease-producing bacteria that may be present. Health faddists claim that it destroys the essential nutrients. Although about 10% to 30% of the heat-sensitive vitamins, which are vitamin C and thiamine, are destroyed in the pasteurizing process, milk is not a significant source of these nutrients in the first place.
    Contaminated raw milk can be a source of harmful bacteria, including those that cause undulant fever, dysentery, salmonellosis, and tuberculosis. “Certified” milk, obtained from cows certified as healthy, is unpasteurized milk with a bacteria count below a specified standard, but it still contains significant numbers of disease-producing organisms.
    Rife Frequency Generator The Attorneys General of Wisconsin and Minnesota have sued to stop an unlicensed woman, Shelvie Rettmann, of Prior Lake, Minnesota, from representing that she cures cancer. In December 1997, Wisconsin Attorney General James Doyle showed that a Wisconsin resident who was diagnosed with advanced colon and liver cancer used Rettmann’s services after being told that she could cure the woman’s cancer. Although medical doctors had recommended chemotherapy, Rettmann had told her otherwise.
    At their first meeting, Rettmann photographed the woman and her daughter with a Polaroid camera and put the photos in a cup fastened to a radionics machine. After informing the mother that she had colon and blood cancer and the daughter that she had breast cancer, Rettmann allegedly advised both to have treatments with a Rife Frequency Generator, a special diet, dietary supplements, a regimen of baths, and something called ‘foot zoning’, which is a type of foot massage claimed to break up accumulated deposits at the end of foot nerve endings in order to help heal the body.
    VAX-D Therapy
    The VAX-D Therapeutic Table is a motorized traction device which is used to stretch the lower back. VAX-D is an acronym for “vertebral axial decompression.” The device is a two-part table in which the upper part is fixed to the table frame and the lower part slides back and forth to provide sudden intermittent traction. The patient is then anchored to the lower part by a pelvic harness.
    VAX-D therapy is usually provided on an outpatient setting for the purpose of relieving back pain. Its providers,pnuematic valve including chiropractors, medical and osteopathic physicians, and physical therapists, commonly recommend twenty sessions of 30-45 minutes, with a total cost of several thousand dollars. During the treatment, the patient lies face-down with the upper part of the body on the stationary portion of the table, and with arms overhead, grasping handles attached to the this part of the table. A pneumatic cylinder drives the two parts of the table apart and together to provide gradual stretching alternating with relaxation of the stretching. A typical cycle includes a minute of each half.
    Auditory Integration Training
    Abbreviated as AIT, this was developed as a treatment for autism by Guy Berard in France in the 1960s and since was introduced into the United States in 1991. It has also been advocated for children and adults with learning disabilities, attention deficit disorder, depression, migraine headaches, and many other mental conditions.
    Proponents claim that individuals with these disorders have hearing that is disorganized, hypersensitive, different between the two ears, or otherwise abnormal. The first step in AIT is an audiogram, a diagram that determines the auditory thresholds to more frequencies than are typically measured during hearing tests. Suitable individuals then undergo training sessions, which are typically two half-hour sessions per day over a 10-day period, that involve listening to music that has been computer-modified to remove frequencies to which they are hypersensitive.
    The American Academy of Pediatrics and the American Academy of Audiology have warned that no well-designed scientific studies demonstrate that AIT is of any use. AIT devices do not have FDA approval for treating autism, attention deficit disorder, or any other mental condition. In 1997, the FDA banned the importation of the Electric Ear or any other AIT device made by Tomatis International, of Paris, France, and they are now illegal.

  • Make Your Job Easier With Tyre Machines And Wheel Balancers

    Posted on July 31st, 2009 admin 2 comments

    Tyre machines have proven to be an asset to workshops and garages, as no longer workers have to struggle with changing tyres.of pneumatic cylinder.Automobile accessories are associated elements of a vehicle, which help in increasing the efficiency and appearance of a vehicle. The vehicle accessory of top quality beautifies the incomplete and plain area of the vehicle by its charm and attraction.
    One such important accessory of any automobile is its wheels. Wheels or tyres guard the performance of a vehicle as well as protect lodgers. Wheels are the key constituents of a vehicle and to guard the rims of a wheel from damaging while changing of tyres, tyre machines is one of the effective means. Earlier, steel rims were more common than any other type of rims but were quite heavy in weight as compared to the alloy wheels, which are quite light in weight.
    Nonetheless, steel rims are very easy to repair, where as the alloy wheels are tough to mend but are simple to accelerate. Indeed, steel rims can be re-shaped into its usual shape easily by using a simple hammer where as alloy wheels cannot be brought back into its shape as it generally breaks but with the help of tyre machines all kind of wear and tear of tyre can be taken care of.
    Today a large number of tyre machines are available that are ideal for both small workshops as well as garages, which helps in changing and maintaining the tyres of the vehicles. By using these tyre machines, it becomes very easy to demount and mount the tyres.
    Tyre changers operate both on the lower and upper bead that tenderly removes the tyre or rim from the wheel and lessen stress as well as damage. The tyre machines are easily obtainable in the market and that at also at very affordable rates. These high performance tyre changers are an excellent substitute obtainable for mounting and demounting of the vehicles tyres.

    These machines have the aptitude to grip a tyre of any size. Remote control unit, lubricated unit fitted, air powered bead breaking system and two pneumatic cylinders are some of key features of these tyre machines.
    Complete with an extraordinary mounting tool and polyurethane tool as well as the standard steel mounting head, the tyre machines provides an integrated security for the alloy rims. Additionally, the mounted spoke tool along with its extraordinary surface treatment has the ability to change any wheel, reduces the friction on the tyre and also has features of rotation and angle adjustment.
    With the help of tyre machines, the most tough wheels and tyres can be de-mounted and mounted in an easy and safe way. The incorporated central locking system laser guides the lower and upper bead breaker and the computer-regulated rotation speeds up the functioning of the tyre machines.
    The fully mechanical tyre machines pneumatic cylinders and wheel balancers also feature LCD display and are semi-automatic and swing arm machine, which are capable to mount the tyres up to 24 inches rim. Tyre changers also include a wheel balancer with an automatic distance data input and rim diameter, which is fully proficient and motorised to grip 24 inches rims with the hidden and special weight functions along with guided programs relating to weight placement.

  • Throttle Pressure and Throttle Response

    Posted on July 26th, 2009 admin 7 comments

    From a technical point of view, throttle response can be measured by how fast your engine can build vacuum in its intake manifold, via throttle pressure. The faster and higher peak vacuum is reached in the intake manifold, the higher the pressure differential will be between outside air, and your engine. This pressure differential forces the air to flow from the area of high pressure (outside air) to the area of low pressure (the engine and pneumatic cylinders), and the higher the pressure difference, the greater the pressure force, and the faster the air flow into the engine.
    This is essentially how throttle response works. To improve throttle response several engine alterations can be used to achieve a higher peak vacuum in the engine or a faster change in vacuum per throttle input… some of these include:
    1- Using undersized intake pipes and intake plenum runners to increase the airflow velocity in the intake system, making the engine able to suck all the air out of it faster and create vacuum sooner.
    2- Adjusting intake cam timing to open the intake valve as peak vacuum is created inside the cylinder near bottom dead center.
    3- Reducing the overall intake system volume, by using smaller manifolds, less vacuum lines, and more electrically operated (rather than vacuum operated) engine auxiliaries which means the engine has less air volume to clear from the intake system to create a vacuum in the manifold to force new air in.
    4- Using cam separation and cam overlap (when both intake and exhaust valves are open at the same time) to have the previous cycle’s exhaust gasses help pull in fresh intake gasses for the beginning of this combustion cycle.

    One interesting application of this concept is the G-Power supercharger kit for the BMW M3. The ASA supercharger powered kit focuses on response and efficiency rather than on astonishing peak power figures. The G-Power kit utilizes a very conservative boost supercharger by ASA giving a peak of only 4.4 psi of boost. Since the engine already very highly powered at 420hp, the addition of just 4.4psi of boost results in well over 500hp (as a conservative estimate) and as much as 560hp as a result of this combination.
    The focus of the G-Power kit is not just power figures, as rather than just providing a supercharger kit for the M3, G-Power has designed a completely new intake manifold for the M3. The manifold although has higher volume than the original M3 manifold (for more peak power as this is now a supercharged car), does have a narrow profile that promotes high air velocities to improve throttle response. Furthermore, the new manifold has integrated individual runners for each cylinders complete with trumpet style inlets raised from the air cylinder floor of the plenum, which has been proven through fluid flow simulation to reduce boundary pressure differentials, reduce the pressure drop inside the intake manifold, and promote higher air velocities that lend themselves to higher peak vacuums and faster vacuum buildup inside the manifold.
    Even though centrifugal superchargers typically show a linear boost curve with engine rpm, and thus produce little to now power gain in lower rpms, the combination of this supercharger with the redesigned intake manifold and new tune reportedly provides over 20% increase in torque at ALL engine rpms, and with increased response.
    Here it is in G-Power’s own words:
    Air duct: Sport air filter system, CAD-FEM flow optimized boost recooling system consisting of an air duct made from aluminum cast, high capacity air-to-air intercooler made from aluminum cast in the car’s front and a large volume air box made from aluminum cast, including 8 integral resonance induction pipes made from light polyamide, ensuring an optimal throttle response and a perfect torque curve; pneumatic controlled, engine load related boost control; boost level approx. 4 psi rel.
    The G-Power kit comes in 3 power ranges corresponding to 4, 6 and 7psi of boost. The 7psi kit with their full titanium exhaust is capable of peaking out over 580 hp with great response to match. Last but not least, the new G-Powered M3 is capable of doing a 0-124 mph 2 seconds faster than a factory M3, which at those speeds is about 20 car lengths of distance between the two cars. Moreover the G-Power with its unlimited speedometer will keep pulling all the way up to 223mph!

    The version 350 CDI Blue EFFICIENCY is that of smaller consumption of the range Class S. It has a diesel engine of six cylinders in V of 2,987 cm³ that gives 235 CV.
    Is a motor of capable and smooth pneumatic cylinder operation to move with certain ease the car? Only to travel very loaded in highways where that to do progresses often have can be remained somewhat just.
    This motor consumes 7.6 l/100 km (0.1 liters more with bodywork extended). The following Class S more next by consumption of fuel is the S 400 HYBRID, that has a total power of 299 CV supplied jointly by a motor of gasoline and another electric one of 20 CV. The consumption endorsed of the S 400 HYBRID is somewhat greater, 7.9 l/100 km, but the necessary disbursement to acquire it in a lot greater, since costs some 13,000 € more.

    In the 350 CDI Blue EFFICIENCY Mercy-Benz has applied some improvements so that the consumption be possible the lower thing. It has the lower part of its bodywork careened to reduce the resistance aerodynamics to the advance and a change of automatic marches (of seven marches) that is disconnected of the motor when the car is detained. The only car of similar size and power that spends less is the BMW 730d of 245 CV (7.2 l/100 km).
    An aspect that distinguishes to the Mercy-Benz class S is the smoothness with which it displaces. To the interior few noises they arrive and vibrations, for which to travel in it turn out to be really pleasant.
    The Class S has pneumatic valve suspension of series, call “AIRMATIC” that gives very good relation between stability and comfort. This suspension gives the possibility to adjust two levels of height of the bodywork. The suspension “AIRMATIC” also modifies the hardness of the dampers automatically in function of the situation, though there are two selectable programs by hand.

  • Pneumatic Jackhammers

    Posted on July 12th, 2009 admin No comments

    Jackhammer, also known as a pneumatic valve or pneumatic jackhammer, is a handy percussive drill powered by compressed air. The pneumatic drill is used for a variety of tasks that may include drilling rock, break up pavement, and various other tasks that require powerful hammering. The pneumatic jackhammer works similar to a hammer and chisel, by jabbing with its bit, not rotating it. The pneumatic jackhammer is one of the most popular rugged tools that are available today. Although, the portable pneumatic jackhammer is not viable for use on walls and steep slopes, as it relies on the inertia of the mass of its body to drive the bit into the work, and directing that mass when not supported by the work is difficult.
    Also, for the pneumatic jackhammer to be effective, gravity is required to bring the mass back into contact with the work after each blow. For using the pneumatic jackhammer effectively, the operator may bend over the tool to assist but is not really capable of overcoming the forces involved when not assisted by gravity. A technique developed by experienced laborers is the use of two man teams to overcome this obstruction of gravity. One laborer operates the hammer and the second assists by holding the hammer either on his shoulders or supported in his arms. Both men can use their collective weight to push the bit into the workface. This method is widely referred to as horizontal jack hammering. Another method is overhead jack hammering, which requires strength conditioning and endurance to hold a smaller jackhammer, called a rivet buster, over ones head.

    Jack hammers are widely used in construction projects. The jackhammers find a typical use particularly for knocking down and putting up the foundation of structures. However, the pneumatic jackhammers also find extensive use in the fields of excavation and mining. The pneumatic jackhammers are one of the important tools. The pneumatic jackhammers are faster and more efficient than the traditional hammer-and-chisel. Thus, when employed in projects which demand tasks to be finished in time, the pneumatic jackhammers come forth as the most reliable solutions. The pneumatic jackhammers are thus especially needed in demolition projects that need to be finished in time.
    The pneumatic cylinder jackhammers are quite difficult to operate considering the tasks they perform and require some basic skills to work with. Therefore appropriatecare should be taken whenever they’re used. To promote occupational safety, construction companies must require their operators to read a pneumatic jackhammers guide. Before you start using the pneumatic jackhammer, it is strongly recommended that you wear your safety gear when it. The recommended safety gear is mentioned clearly in the user guide but generally include boots, gloves, goggles and ear muffs. While operating a pneumatic jackhammer stout clothing helps too. Usually the bits of the jackhammer get very hot in operation so use caution handling them. The rest of the machine can get quite warm also. So it is always better to count on the safety precaution while operating a pneumatic jackhammer.

  • Reliable Pneumatic Conveying

    Posted on July 8th, 2009 admin No comments

    Atlas Food Processing Systems has over 60 years of experience in the bulk handling industry and has supplied over 1,000 pneumatic conveying systems to bakery and food processing companies.
    Pneumatic cylinder conveying of bulk solids is an established and accepted method of both transferring and accurately feeding materials into downstream processes such as mixers and blenders, and for packaging and distribution systems.
    It must be said, that the most important consideration in providing a reliable conveying system, must be given to the specific characteristics of the conveyed materials, such as its bulk density, particle size, moisture content, abrasiveness, fragility and sensitivity to temperature.
    Consideration of the materials specific characteristics allows the selection for the most appropriate method for conveying the material. The reliability of the conveying system is also dependant on the design and installation of the conveying system.
    Once the specific characteristics of the material to be conveyed are identified and the appropriate conveying method selected. Consideration of the batch sizes, batches per hour and the number of delivery points allows calculation of the conveying rate, which will satisfy the production requirements.
    Having established the conveying rate, the next step would be to select the ideal conveying pipe diameter and feeder, which will guarantee throughput tonnage, and ensure reduced power consumption.
    When establishing a pipe route, it is good practice to consider using horizontal and vertical pipe runs. This will ensure a consistent and stable flow of material during conveying.
    It is best to avoid inclined pipe runs. Inclined pipe runs affect the efficiency of the conveying system because the material will tend to drop out of the air flow and descend back down the pipe. At best the material will be re-conveyed back up the pipe and at worst could develop pneumatic valve into line blockages at the bottom of the inclined pipe section.
    Always use straight conveying pipe lengths between bends to allow the conveyed material to accelerate to its desired velocity after each bend, and thereby reduce the overall pressure drop in the system.
    Some times overlooked is pressure drop in the supply line from the blower, particularly important if the blower is located some distance away from the pick-up point, and also the increase in temperature due to the compression of the conveying air.
    The use of long radius bends will reduce wear and pressure loss within a system although tee bends can be sometimes used on fragile or very abrasive products.
    In a conveying line of constant diameter the conveying pressure drop is directly proportional to line length. As the pressure drops the air volume increases, which in turn increases in air velocity. High material velocities will lead to increased wear on bends and material degradation.
    The simplest way to avoid the excessive pressure drops and increased conveying velocities is to ensure that conveying lines are installed taking the shortest route possible to the discharge point and using as least bends as possible.
    Apart from improved reliability, the other benefit of using shorter pipe runs is reduce the burden on the conveying blower, which means cost savings on power consumption.
    Alternatively, if it is not possible to have short runs to compensate for the increase in air volume and relative air velocity a technique called “line stepping” can be used to increase the pipe diameter at selected points along the pipe run.
    Line stepping is an effective technique to reduce conveying line pressure and ensure constant conveying velocity in the pipe line. Promoting a more efficient and stable conveying system, reducing wear on bends and product degradation

    .
    Never step a conveying pipe before a bend and it is always good practice to step pipes six metres after a bend.
    Rotary valve feeders can also have an affect on the reliability of the conveying system. The rotary valve’s pockets are full until the material is discharged into the conveying line. The empty pockets are then pressurised by the conveying air. If not vented the pressurised air in the empty pockets will pass into the silo and the material above the rotary valve leading to bridging.
    One of the simplest ways to avoid this problem is to use a rotary valve that incorporates an outlet for venting the empty pockets. The air can then be vented to a air/dust separator and any carry over can be automatically re-introduced into the conveying system.

  • What Is A Pneumatic Sealless Tool And What Industries Would Benefit From Having This Tool?

    Posted on June 25th, 2009 admin No comments

    A pneumatic sealless tool is a tool that is not generally used within a home environment, but is used in an industrial setting where it is necessary to strap together products for shipment. A homeowner who may buy one of these tools may find that they would be better off with duct tape or some rope for strapping materials rather than a pneumatic valve that is used forstrapping heavy items together.
    The pneumatic sealless tool is a handheld tool that is great for strapping flat packages. Its light weight and its air motor for tensioning is a great way to save time when strapping packages together. In fact, the sealless joint eliminates approximately 10% of the cost by eliminating seals. It even allows for tension adjustment for different types of packages since no two packages will require the same degree of tension depending on the materials.
    These are great for strapping such materials as wood slats like those used in wood flooring. The sealless joint’s efficiency is quite high and is higher than those joints that use a separate seal. It can be used both horizontally and vertically and can be used in just about any industry that requires any type of flat packaging to be strapped together for safe shipping.


    Of course there are different types of these pneumatic sealless tools on the market. They can be used with one type of steel strapping or they can use two different type of steel strapping. A good example of this is a pneumatic sealless tool that uses standard steel strapping, which can be found in widths of anywhere from 10mm to 19mm and the thickness can be anywhere from 0.38mm to .60mm. Other pneumatic sealless strapping tools may also use other types of steel strapping that is as thick as .63mm. It depends on what size packages need to be strapped and the strength that is needed on whether or not standard or tensile steel strapping is needed. There are also pneumatic sealless tools that use strapping as much as 32mm wide and 1.30mm thick for those even larger packages.
    As stated above, any industry shipping flat packages can benefit from using these tools. For those smaller jobs, a business may only need a pneumatic sealless tool with steel strapping that is 10mm wide and only .38 mm thick, but another company may need to bring out the big guns and use a pneumatic accessories that usesstraps that are 32mm wide and 1.30mm thick.
    The great thing is that these tools make strapping easier than doing it by hand and it can prevent injuries and save time. However, it is important to ensure that the right size tool is acquired to make sure that all jobs are done efficiently. If the tool is too small, then the strapping that is being used may not be adequate for the weight of the material, so it is better to be too big than too small when shipping heavy items.
    Strapping that is not thick or wide enough can still break under large amounts of pressure and this could cause personal injury if anyone is in the vicinity of the product if such breakage occurs. That is why it is important to assess the weight of the material being transported.


  • Linear Actuators 2

    Posted on June 22nd, 2009 admin No comments

    Linear actuators are described as devices used to convert or transform motion from any supply of energy in a linear-like form and not necessarily rotationally such as electric motors. When linear actuators are applied as force, they become a mechanical apparatus that obtains energy usually constructed by the air, electricity or liquid and transforms it to a particular form of motion. This kind of motion can transmit to anything from blocking, clamping to ejecting. Actuators are usually used in the manufacturing industry or industrial applications and may also be used in various objects like switches, motors, pumps and valves.
    From all types of linear actuators available in stores, the major common type is the one that is powdered by air. These types of linear actuators are also known as the pneumatic cylinder or the air cylinder. These pneumatic cylinders or air cylinders are usually made air tight, normally made of metal. They normally make use of the energy of compressed air for them to shift a piston. Additionally, pneumatic cylinders are typically used in the manufacturing and assembly processes. Nevertheless, grippers utilized in robotics, make use of linear actuators powered by the compressed air for them to work akin to human touch.
    Hydraulics or Electricity’s are the main sources of power for linear actuators. However, just like the air cylinders, there is also availability of hydraulic cylinders and electric cylinders. This is whereby the cylinders transform hydraulic or electricity into motion and electricity and hydraulic cylinders are regularly used in various automobiles. Various linear actuators that are accessible have a variety of sources of power. For instance, solenoid valves have the capability of being powered by air and electricity. Electricity usually powers solenoid valve and when air is used to power solenoid it activates the valve.
    Some linear actuators consist of digital readout positions and encoders. There is the resemblance of micrometer knobs for adjustment though they are usually utilized for position adjustment instead of position measurement. Other actuators like hydraulic cylinder or hydraulic actuators naturally have hollow cylinder that has a piston inserted in it. The two sides of piston are pressurized or de-pressurized alternately to attain a precise and controlled linear displacement for piston as well as entity connection for piston. Physically, the piston linear displacement is within piston axis or cylinder and design is usually based on hydraulic principles.

    There is a way in which linear actuators work. They have motors that normally rotate the drive screw by use of synchronous timing belt. There are other linear actuators that use direct drive or worm gear drive. Both of them can turn the screw hence it pushes a nut drive to the screw. This in turn shoves the rod and rotating of screw in all directions retracts the rod. Actuators have a cover tube that protects screw nut from contamination and environmental elements hence enabling use of machine constantly without it getting stack. Radial thrust allows the screw to rotate liberally beneath the conditions that are loaded and provides strength to the actuators.
