* Improved vehicle aerodynamics have decreased wind resistance and made the vehicles more "slippery."* Down-sized engines have reduced engine braking by compression.* Higher speed rear axle ratios have reduced mechanical retardation.* Radial tires have reduced rolling resistance.* The movement toward smaller wheels and low profile tires require the smaller brake to absorb the same amount of energy as the standard 16-1/2 x 7-in, brake of today.It is no wonder that brake specifications have assumed such a predominate role when purchasing equipment. Fortunately, for truck fleets and the motoring public alike, government is playing a major role in demanding certain brake performance standards on new vehicles.How do all of these government standards help the truck fleet manager when specifying air brake systems? Actually, the standards assume the major responsibilities for proper braking of new vehicles. However, the fleet manager still has certain obligations:

"Backpack sprayers for agriculture are the biggest application currently, but the inventor wants to expand applications to food and pharmaceutical," says Richardson. "Being an engineer myself, I saw that the potential uses were very broad. Plant managers and engineers always want to tweak a valve, but because this has a pre-set pressure, it becomes tamper proof."The first application in the beverage arena is likely to be foodservice. Vendors are notorious for altering the syrup/carbonated water ratios in drink dispensers, a practice that manufacturers abhor.

Though light in weight, Airbor magnetic drill has a powerful 1.6-hp air motor and 1,600-lb magnetic holding strength. With its extra rack, stroke length is extended to 10 1/4 in. Annular cutter capacity is up to 2 1/16 in. diam. Geared chuck adapter converts the unit to a standard drill press. The Slugger Air Force pneumatic drill, at 24 lbs, 6 1/4" high, is useful for confined area drilling. The drill''s features include a permanent magnet that turns on or off by air power, a cutter capacity of up to 1 1/16" diameter x 3/4" depth and the ability to use ShortSlugger cutters and frame cutters. These cutters'' geometry allows the operator to drill multi-layered truck frames in a single pass.
