The months of January, February and March are usually the coldest of the year with temperatures often dropping below zero for long periods.
Transport managers protect their vehicles by filling coolant systems with anti-freeze, though some buy the cheapest without paying attention to quality and risk subsequent mechanical trouble. I have recently learnt about Carbural Radmaster radiator fluid which besides serving as an anti-freeze offers protection from corrosion and overheating.
Leaks in the coolant system are easily traced because a green fluorescent additive in the fluid shows up under an inspection lamp to reveal the leakage paths which can then be traced to their origin. Radmaster can be left in the coolant system throughout its service life.
Produced by United Lubricants Ltd, Station House, Harrow Road, Wembley. Middx. quantities at £36, £23.75 and E5.25 respectively.

Landing legs
Single-speed, twin-speed or automatic landing legs are now being marketed under the Europa Mark 7 name by intertruck.
The supports will lift up to 20 tons and have • a static load capacity of 35 tons. The two-speed version has a positive locking mechanism to prevent accidental disengagement of the permanently lubricated gears.
The gears and shafts are splined, not pinned, for good gear alignment. All the legs incorporate a two-start metric lead screw with rolled acme thread, in a sealed grease bath for permanent lubrication, easier operation and maintenance.

Cutting oil
Rods F6 cutting oil from Foseco (FS) contains no mineral oil and can be treated as easily as domestic sewage it is claimed, when "tramp oil" has been skimmed off. Further because of its formulation, the risk of developing dermatitis is greatly reduced.
F6 has no odour, protects metal components from rust and does not leach out or emulsify lubricating oil from machine slides etc. Tramp oil, grease and dirt can be skimmed from the oil surface.
Normal dilution is 20-1, though it can be used safely in' different concentrations including undiluted.
Price per 47gat drum £31.22, 5 gal drum £4.25.

Unmanned fuel dispenser
Beck has developed an unmanned fuel issuing system for 24-hour operation, called the Tank-King.
Similar in appearance and size to other fuel dispensing pumps, the pump motor cannot start unless an appropriate key is inserted and pump channel selected. None of the keys are duplicated. While fuelling, the amount drawn is automatically recorded against the keyholders own counter in a central cabinet.
There are two dispenser models, one with a 10gal per min flow rate and the other 20gal per min. Each is built to accept either 24, 48, 72, 76 or 120 keys.
Price: 10gal per min 24 key £690.50 20gal per min 120 key £1607.00: Made by: Beck & Co (Meters) Ltd, Beckmeter Works, Streatham Vale, London, SW16 5HP.
Space heaters
Two vented portable space heaters designed for use where the products of combustion are unacceptable or where ventilation is restricted, are marketed by W. C. Youngman.
The two Master Spaco heaters, the BV 125E and BV 250E, give heat outputs of 88,000 and 210,000 BTU /hr. respectively. Based on their direct-fired counterparts, many parts are interchangeable.
The BV 125E measures 42in. x 19in. x 24Th. and weighs 80Ib. The .BV 250E measures 51in. x 20in. x 32in. and weighs 2171b. Fuel consumptions are approximately 0.5 galls/hr. and 1.2 galls/hr.
Marketed by: W. C. Youngman, Manor Royal, Crawley, Sussex.
Cleaning unit
The latest addition to the range of hot-and-cold-water power cleaners produced by Contractors Pumps (Tamworth), the model 800 has a heating coil ventilation system and is constructed as a complete unit. If necessary, the coil can be changed in an hour. Designed for continuous operation the cleaner delivers 3gal of water per minute at 800 psi. The pump is a four-piston Hypro unit that operates at 1425 rpm and is powered by a 2 hp motor.
Said to be particularly advantageous in the case of a contractor with a continuous cleaning need, the equipment is suitable for semi-permanent installation. Water and electricity can then be permanently connected and switched on and off as and when required. For this purpose the machine is supplied without wheels and cover.
The combustion chamber is of the reverse-flow baffled type and its ends are ceramic-lined. The coil comprises 100ft of heavy wall steel tube, while the high-pressure, wire-armoured steam hose is 30ft long. Fuel consumption is 1.5 gal /hr. A Nu-way ZL2D burner has pressure jet automatic ignition, and other features include water and fuel tanks that are integral with the body, the detergent tank consisting of a polythene drum; detergent is introduced to the machine by means of a small valve. Filters are fitted in fuel, water and detergent lines. Safety devices include an unloader to protect the pump and coil and a pulsation damper that balances surges.
Having a length of about 56in. (140cm), a width of 34in. (86cm) and a height of 34in. (86cm), the cleaner weighs 450Ib (204kgm) when dry. It is fitted with three solid 9in. castors.
Price: £500.
