As previously, the torque converter is fitted between the engine and standard clutch and gearbox of the transmission. Besides ensuring faster working cycles and avoiding stalling or labouring of the engine, the torque converter cushions shock loads and reduces general wear.
Safety Flooring A NON-SLIP floor coating has been produced by the Minnesota Mining and Manufacturing Co., Ltd., 3M House, Wigmore Street, London. WI, known its Safety Walk. It can be supplied in cleats, strips and rolls, and consists of extremely hard mineral grains, surface-coated on a tough fabric said to be unaffected by oil, petrol or weather. High wear resistance is also claimed.
Three types are available, A, B and D. Type B is self-adhesive, whilst type A, also self-adhesive, is desirable for rough surfaces, such as concrete floors or where dust or moisture cannot he entirely eliminated at the time of laying. Type D is stated to be non-sparking and suitable for applications where there is a risk of explosion or fire.
Oil-engined Welding Set A N oil-engine powered arc-welding set, known as the type DEB.400U and providing characteristics similar to the MGB.400 (The Commercial Motor, September 13) has been introduced by Quasi-Arc, Ltd., Bilston, Staffs. Weight without undergear is 19 cwt. The apparatus is 4 ft. 2 in. long, 2 ft. 3 in. wide and 4 ft. 2 in. high. The
N.E.M.A. rating is 300 amp. D.C. at 40 arc volts, 60 per cent. duty cycle.
A Ford four-cylindered industrial oil engine is employed and has a capacity of 3.61 litres, with a rating of 40 b.h.p. at 1,500 r.p.m. A feature of the welding set is a fully automatic idling device. Pneumatically operated, it is arranged to slow the engine to idling speed automatically when welding is not in progress. A pre-set adjustable time delay prevents the engine from idling during short pauses in welding.
In its standard form the equipment is mounted on a four-wheeled pneumatictyred undergear for hand towing, but it can also be supplied mounted on brackets for stationary use, or on a twoor fourwheeled road towing undergear.
Lubrication Guns Improved THE Porn-Porn hand lubrication gun produced by Tecalemit, Ltd„ Plymouth, has been improved. The newdesign guns are now in production and available in two sizes having capacities of 5 oz. (type LP) and 31 oz. (type MP).

may be achieved.
Both types of gun can be obtained with hydraulic. Tat-hexagon or Tecazerk con. neetors. Prices are unchanged.
