Electrostatic Painting

AT present electrostatic paint application, whereby the object being painted and the paint itself are electrically charged, has not been used extensively for vehicle finishing.
However, as electrostatic painting Aar becomes easier to use and more flexible in operation the method may be extended into this field. A step in this direction is the introduction by Aerostyle, Ltd., North Acton, London, N.W.10, of the Statron electrostatic paint gun.
This unit is unlike a conventional compressed-air gun as the paint is thrown from a spinning " bell " by centrifugal force and thus atomized. The gun, and therefore the paint, is charged by the 90,000-v. output of the Sames generator supplied with it and the painted object is earthed.
As the paint is positively attracted to the earthed component, overspray and fog are almost eliminated. This effects a considerable reduction in paint consumption and in overheads as extensive air extraction equipment is not required to maintain cleanliness.
Clean Floors
L"OR removing grease and oil-bound dirt from garage floors, Holt Products, Ltd., New Addington, Surrey, offer a floor cleansing compound in crystalline form. When applied cold, the crystals are broadcast over the floor and sprinkled with water. The resulting solution is left to soak in for at least an hour and the grease and dirt are then loosened with a broom or scraper and hosed away.
For quicker results the cleaner is mixed with hot water before being applied to the floor. The compound does not harm tyres and costs from 3s. Id. for 2 lb. to £5 5s. per cwt.
Rack Reduction
THE price of the standard roof rack for Bedford CAS and CAL light vans has been reduced from £5 17s. Cd. to £5 5s. This has been permitted by increased production and similar redtictions apply to the racks offered for postwar Vauxhall cars.
Ticket Disposal LLITER and used tickets collected from. public service vehicles during cleaning can provide a difficult disposal problem. William Palfrey, Ltd., Palfrey House, 24 City Road, London, E.C.1,
feel that their paper refuse sacks are the answer to this.
The sacks are provided with metalstands to hold them open and hinged covers. After filling, the mouth of the sack can be closed by a normal stapling machine and it can then be stored to await removal without fear of the con• tents being spilt or blown about.
Wave-on Gimmick APLASTICS sign for attachment to the rear of vehicles reads "Please Pass" when illuminated. It is manufactured by Davis (Fixers), Ltd., Foss Islands, York, and is said to have been approved by the police. The sign costs £3 17s. 6d., measures 7 in. by 4 in. and incorporates a 6-w. bulb.
