Water Blaster
Fast cleaning of equipment and machinery and wet sandblasting are the dual capabilities of the new Challenge Water Blaster.
A product of Challenge Cook Bros., Inc., Industry, Calif., the Water Blaster utilizes an entirely new concept in pumping-the simplest high pressure pump ever developed. Delivering volumes up to 50 gallons per minute and pressures to 800 psi, this compact pump produces a jet stream that blasts off caked-on mud, dirt and grease that accumulate on construction and industrial equipment.
Sand is added to the powerful stream by merely turning a valve, enabling the Water Blaster to remove paint, rust and other deposits from metal, wood and masonry surfaces.
Extensive field tests indicate that the Challenge Water Blaster saves one-half to two-thirds of the time normally required for equipment clean-up. The time saved is subtracted from the downtime required in the normal maintenance of equipment, machinery and buildings.
The "heart" of the Water Blaster is a unique, patented "rotary case" pump which has only two working parts and only eight parts in all. Belt driven by gasoline engine or electric motor, the entire pump case rotates, drawing water from any primary source or from a large capacity surge tank mounted on the rig. The centrifugal force of the whirling mass of water drives some of it into a stationary tube arm within the case. This collector arm feeds the water at high pressure and high volume through the discharge hose and spray gun nozzle.
Discharge hose can be extended to 100 feet from the pump without significant loss of pressure. A simple "deadman" control at the nozzle starts and stops the flow at the pump-preventing the danger of a "whipping" high pressure hose.
For water/sandblasting the Water Blaster method uses from 200 to 1,800 Ibs. of sand per hour depending on the work requirement. Sand is picked up from a pressure tank that has no moving parts. Volume is controlled with two valves. All air pollution hazards are eliminated. The Water Blaster wet sandblasting method can be used on metal, wood and masonry surfaces including large buildings and structures.
The Challenge Water Blaster is available mounted on a single-axle or tandem-axle trailer. The pump is driven by an air-cooled gasoline engine. The skid-mounted model is also available with an electric motor. Complete information can be obtained from Challenge-Cook Bros., Inc., 15421 East Gale Avenue, Industry, Calif. 91745.
Thirst Quencher
A new thirst-quenching beverage that the body absorbs about 12 times faster than water is now being made available to industry and commerce after extensive use by athletic teams.
The specially formulated product is particularly satisfying during periods of physical exertion when liquid intake frequently is limited.
Called Gatorade, the beverage is being marketed by Stokely-Van Camp, Inc., a major producer of canned and frozen food products.
Gatorade thirst quencher is a non-carbonated water solution containing glucose and inorganic salts that is quickly absorbed by the body to help replace fluids lost mainly through perspiration during periods of exertion. It has a pleasant lemon-lime flavor.
Gatorade gets its name from the University of Florida, where a group of researchers developed the drink and tested it on the school's football team, nicknamed the Gators. Players found they could drink as much as they wanted during a game. Some consumed as much as 1½ gallons.
Most of the nation's professional football teams including the Green Bay Packers and the Oakland Raiders and many collegiate teams used the thirst-quencher during the past season. Gatorade also is finding great favor among athletes in other sports.
Gatorade presently is available in cases of twelve 46-ounce cans. Further information about the product may be obtained from Stokely-Van Camp, Institutional Division, 941 North Meridian Street, Indianapolis, Indiana 46206.
Masonry Anchors
Both external and internal design changes intended to facilitate installation and provide greater holding power have just been incorporated into the Rawl Lag-Shield, according to The Rawlplug Company, Inc. of New Rochelle, New York.
Intended for use with common lag bolts, the shield now features a special horizontal fin which eliminates turning as the lag screw is tightened in the anchor and also tapered annular rings which provide additional resistance to withdrawal.
Die-cast of a special corrosion-resistant zinc alloy, the product is available in both short and long styles in sizes from 4 to 4. The manufacturer recommends using the short style in hard masonry to minimize drilling time and effort and the long style in soft or weak masonry in order to develop the full strength of the masonry material.
Skin Irritation Preventative
Skin irritation from cement is caused by the highly alkaline action of hydroxides of lime present in wet cement, or formed by the dry powder acting on perspiration of the skin. A waterproof barrier cream, KERODEX® No. 71 provides hands and forearms with a protective film which blocks skin contact with wet mixtures or the powder.
The cream is greaseless and stainless, and can also be applied to neck and ankles. KERODEX will not affect the skin even in extended use, and is formulated to protect against chemical irritation, contact allergy, and toxic absorption.
KERODEX is sold directly to industry by Ayerst Laboratories, 685 Third Avenue, New York, N.Y. 10017. Individual 4 oz. tubes are available at drugstores. Literature is available on request.
Material Handling
Literature on its complete line of hydrostatic Moto-Bugs, power operated material handling buggies, available in standing, riding and walk-behind models, is presented by PCM, Division of Koehring Company, Port Washington, Wis.
The Moto-Bugs, featuring smooth fluid drive and deadman safety controls, are available with an interchangeable hopper body or platform bed. New features include extra large, dual drive tires as standard equipment on the R-10 and S-10 models, and available as an option on the W-10 model.
Completely enclosed hydrostatic transmission-which eliminates clutches, belts and chains-results in smoother acceleration and deceleration at all speeds, with fewer parts to maintain. Instantaneous gravity discharge of hopper is controlled through a simple rope design.
