THERE are available various sizes and capacities of a new collapsible box pallet made by Eccles Engineering, Ltd., Brook Street, Redditch, Worcs. The pallets are stackable in the collapsed and erected state, and there are no loose components to be lost or damaged.
To collapse the pallet, the hinged end sections are lifted upwards and folded against their respective side sections. The two sides are then folded on to the pallet base, one on top of the other. An advantage of the design is that either of the hinged sections can be opened for unloading purposes without affecting the stability of the pallet.
Beating Vehicle Thefts PAA NEW security device intended for commercial vehicles is to be marketed shortly by Fairylites, Ltd., Southwick. Hove, Sussex.
Basically the equipment consists of a solenoid connected to the vehicle's dynamo electrical circuit coupled to a shut-off valve fitted to the fuel supply pipe. The solenoid is arranged to operate when the current delivered by the dynamo reaches the value corresponding to an engine speed of about 500 r.p.m. This means that when the system is brOught into operation (by a switch incorporated in the electrical circuit) the vehicle can only be driven a short distance before the fuel supply is cut off.
While the equipment can be fitted to both petroland diesel-engined vehicles, it will be more effective on the latter as the fuel system would need to be bled before the engine could be restarted.
Flasher Unit rAA NEW flasher unit for commercial vehicles has been introduced by ludella Castings, Ltd., The Runway, South Ruislip, Middlesex. It is called the Della Turn Signal Lamp and has an amber blister lens with a rubber base mounting and chromium-plated trim.
List price of a single unit is £1 10s., including the bulb.
Testing Welds BECAUSE of the increasing use of welding in the fabrication of aluminium structures and vessels, the British Standards Institution has produced a standard on methods of testing these welds. It is published as B.S. 3451:1962 and is entitled "Methods of Testing Fusion Welds in Aluminium and Aluminium Alloys." Safer Welding FLASH-BACKS can be a serious problem to operatives using acetylene gas, often causing explosions and fires.
The D. S. Baddelcy Engineering Co.. Ltd., have introduced a unit to solve this problem—the "Tr-Sure" Triple Acting Flash-back Arrestor—which has been approved and tested under the supervision of the Chahner's Test Institute.
In the case of a flashback, the arrestor traps the flame and, when the flame has been stopped and the pressure wave absorbed, a valve comes into action, stopping the flash-back definitely. A gas flow lock also conies into operation and immediately shuts off the gas flow, eliminating the risks arising from the escaping gas. The Tr-Sure Arrestor costs £4 17s. 6d.
Painting Zinc A NEW process has been developed by 1-1 The Pyrene Co., Ltd., Great West Road, Brentford, Middx, for the treatment of zinc or zinc-coated parts prior to painting. The process is known as Brush Bonderite Z and is claimed to provide for satisfactory adhesion of paint to the zinc surface without the need for the installation of special plant.
Application is usually by brush, but when a spray gun is used, parts in contact with the solution should be of stainless steel. No heating of the solution is necessary or even desirable.
Work must be degreased before the application of Brush Bonderite Z. After application, the Bonderite solution should be left in contact with the work for five minutes, after which it should be thoroughly rinsed with hot or cold water.
Coated Nylon Fabrics A COMPREHENSIVE survey of the rA uses of coated nylon fabrics is contained in a_ new booklet entitled "Under Cover with Nylon," which has been published by British Nylon Spinners, Ltd. Separate sections deal with applications for flat sheets, shaped covers. collapsible
containers, protective clothing and miscellaneous uses. Copies of the booklet are available from the concern's Industrial Sales Section, 68 Knightsbridge, London, S.W.1.

The extinguisher is designed for use on inflammable liquid fires and fires involving live electrical equipment, the discharge from the extinguisher being non-conductive.
Fully charged, the new model weighs 29 lb. and the mean range of the discharge in still air is 25 ft. The normal discharge time is 15 seconds, but discharge can be interrupted by squeezing the hand lever at the end of the discharge hose. After use the extinguisher can be reloaded in 60 seconds with Pressure Charge No. 65.
