Butterfly Valves
INTRODUCED recently into the UK is a range of valves I suitable for use on road tankers. Of light weight and available in sizes ranging from 2 in. to 14 in. bore, the valves are of the butterfly pattern. The units are capable of providing 100 per cent shut off up to pressures of about 70 p.s.i. and can be used to accommodate liquids, gases, air, and—equally well— granulates and powders.
Sole agent for the valve in Great Britain is G. F. Hodges. 84 Valetta Road, Acton, London. W3.
Made by Ewald Kraft, WuppertalVohwinkel, Siegersbusch 23/25,' Postfach 179, Germany.
Price: £12 (approx. for 4 in. bore unit). Dual-purpose Oil Cooler THE new temperature-controlled oil cooler made by Kenlowe Accessories and Co. Ltd., is now available for use with BMC vehicles. This unit (part number TOC/1), which is supplied complete with all necessary pipes and clips is expected to be available for fise on all makes of commercial vehicles in about three months' time.
The unit is of unconventional design; the oil is water-cooled rather than air-cooled and the heat exchanger through which the oil passes is sited in the bottom radiator hose.
This equipment serves a double purpose. On starting up the engine, as the engine coolant increases in temperature it warms up the engine oil and afterwards it makes sure that the oil temperature does not exceed that of the bottom hose (normally at a maximum of 75°C).
The cooler is made of brass and copper and is black with cadmium-plated fittings. Installation is normally easier than with the conventional oil cooler as the heat exchanger does not have to be mounted in a position subject to ram airflow effect. Made by: Kenlowe Accessories and Co. Ltd., Burehetts Green, Maidenhead, Berks.
Price: £12 10s. complete.

Versatile Antifreeze AMETHOD of producing an antifreeze to meet the stringent requirements imposed by the use of light alloys in vehicle engines has been developed by Borax Consolidated Ltd. Neobor (pentahydrate borax), an established corrosion inhibitor for conventional engines, is employed as the base.
The new antifreeze is called BMSL, the components being borax mercaptobenzothiazole, sodium metasilicate and lime. It is claimed to have been proved efficient and safe over extended time periods and under severe conditions. Good protection is also provided for rubber and synthetic hoses. A bulletin giving details of test results and so on is available from Borax Consolidated, free on request.
