output of 80,000 Btu per hr. is being marketed by Brown and Tawse Plant Ltd. The unit—called the Anderton Waste Oil Heater— operates on the induced-draught principle and consumes any kind of waste oil at a rate of 0-5 gal. per hour. A garage servicing six vehicles per day recovers enough waste oil to operate the heater for up to 10 hr. per day.
The body of the unit is heavily constructed and weighs about 2 cwt. The design provides that the presence of water on the fuel will not cause a backfire or explosion—instead the heater will automatically extinguish itself. Flue gases are discharged outside the building through a stack, but the diameter of the chimney is not critical to the operation of the unit. Draughts will not affect the heater, which is reported to have been successfully tested in gusts of wind up to 60 m.p.h.
Whilst running, the heater roars like a blowlamp; the fuel. feed is by gravity but as there are no nozzles in the system there is no danger of blockage by foreign bodies in the fuel. If there is an insufficient supply of waste oil then gas oil can be used, costing Is. 3d. per gal.
Two models are available, one providing heat by direct radiaation, the other (incorporating a water-jacket boiler) being capable of heating 350 sq. ft. of radiators and a domestic supply. Marketed by: Brown and Tawse Plant Ltd., Ambrose Street, Manchester 12.
Prices. Model C.H.B. (direct radiation), £90; Model D.S.H. (water jacketed), £120.
ANEW device designed for use in handling bricks of unequal sizes is now being produced •by Bennett Mechanical Handling Ltd. Successful trials of the new brick clamp have been undertaken at the Cardiff works of Welsh Brick Industries (1946) Ltd. with the unit fitted to a Yale 6,000 lb. diesel-engined fork-lift truck.
Instead of the conventional flat rubber grip normally used on brick clamps of this type, the Bennett clamp grip consists of five Neoprene resilient heat-resistant gripper tubes attached to a steel plate. This in turn bears on to absorber-pads of expanded Latex rubber and the steel plate is turned over the backing structure of the clamp to prevent vertical slip under load. The unit is capable of holding rows of bricks differing in length from their immediate neighbours by up to 0.75 in.
