INDUSTRIAL heating units made by Tangyes, Ltd., Cornwall Works, Smethwiek, Birmingham, are now available fitted with a Kemsafe-Tangye wasteoil burner. In addition to unfiltered waste engine oil, diesel oil, paraffin or a mixture of the three can be used with equal success.
The burner is a self-contained unit requiring no outside supply of compressed air and fits in place of the clinker or raking doors on the bottom-section unit of a standard Tangye heater fire box. A special top-section fire box is provided to incorporate a baffle fire brick.
A refractory pot with holes for an air stream to provide satisfactory combustion, and a gravity-fed oil jet in the base are incorporated in the assembly. An 0.167-h.p. single-phase motorized fan suitable for 230,1250v. provides air pressure which is regulated by a butterfly valve in the air pipe. Oil supply is by way of a fine adjustment valve in the pipe line.
Safety devices are incorporated and the cost of the unit is £111 10s. An airflow attachment is available as an optional extra at £36.
Trailer for Two
A SMALL four-wheeled close-coupled
trailer designed to transport two small cars is now in production with liaison Trailers, Ltd., Robinson Road. Newhaven, Sussex. They can be handled by Land-Rovers or small commercial vehicles and are said to be capable of towing at high speeds. Basic price is £275.
Also under construction by the same concern is a two-tier trailer of a similar size for carrying four medium-sized cars with the top ramp elevated by hydraulic rams. This trailer can also be used behind the Land-Rover.
Setting Twin Heads
TVIN headlamp light units can be adjusted easily with the Easobal Aligner introduced by Booth Patents, Ltd., Much Park Street, Coventry.
In use the instrument is set to the required angles on scales provided and held against the lens of the lamp which, if necessary, can then be adjusted by the normal means, until the spirit level in the Aligner shows the correct reading. Accuracies of better than a quarter of a degree are claimed to be possible.
The instrument can be used when the vehicle is on ground inclined by as much as 4° from the horizontal, so that a perfectly level floor is not necessary and as the weight of the instrument is not suspended on the lamp by a sucker or other means the lamp cannot rise to an incorrect setting when the weight of the instrument is removed.
Anti-freeze Plus
AN inhibited anti-freeze solution which gives warning of acidity in the cooling system has been introduced by Molts Products, Ltd., Vulcan Way, New Addington, Surrey. It is known as Cilycolmaster and when added to the cooling system as a 25 per cent, solution turns the water red, but when the inhibitor in the anti-freeze is exhausted, the coolant will turn yellow. If this happens, protection against corrosion is obtained again by adding neat anti-freeze until the colour returns to red,
Glycolmaster is made to B.S.S. 2537 (Ethylene Glycol) and B.S.S. 506 (Methanol). The inhibiting system used is the same as in anti-freeze manufac tured to B.S.S. 3152. A 25 per cent. solution protects against complete solidification down to —18°F. and against mush to —3°F. Comparable figures for a 33; per cent, solution are —41°F. and —23°F. respectively.
Retail price is 9s. 6d. for a 3-pint tin and £1 5s. for a 1-gal. can.
