Aircraft Lubricants for A NEW grease for use in
Use in Commercial cars and commercial Vehicles vehicles, based on a war-time development for aircraft, is now commercially available in America. Originally made with lithium, it is at present being manufactured with sodium, calcium or aluminium. The grease is claimed to be suitable for all parts of a vehicle which require greasing, whereas the normal lubricant is not usually considered an all-purpose product. The new lubricant retains its properties between the temperature range of minus 30 to plus 300 degrees F., and lasts four times as long as ordinary grease. It is claimed that on tests with lithium grease in a heavy vehicle, one greasing sufficed for 40,000 miles, compared with approximately 10,000 miles with ordinary lubricants. The product costs no more than the orthodox types of grease.
Enormous Scope for THE exhibition at Olympia Mechanical Handling A of mechanical handling Equipment . . . equipment could not have
failed to impress anyone concerned with the quick transport of goods in factories and other industrial establishments. Although the mechanical handling industry is only in its infancy in this country, this exhibition provided sufficient proof that we are already producing equipment of a high standard of efficiency. In view of the nature of the work performed by fork-lift trucks and normal load-carrying trucks, their initial cost should be saved over a period of about 12 months.

Should Directive on 140W far should a Licensing Traffic Influence "Authority be influenced by Licensing Authority ? a directive to divert traffic
from rail to road? The question arose during the hearing of an appeal, when the East Midland Licensing Authority, who had received such an instruction, said he felt that he must bear it in mind when considering whether railway facilities would be adequate. The Appeal Tribunal ruled that any diversion of this nature would be for only a limited period, and that the Licensing Authority, as Regional Transport Commissioner, had ample powers to make provision to meet any difficulty that might arise from a shortage of railway wagons. Therefore he need not be influenced by the directive in reaching his decision on an application for a fullterm A or B licence.
An Automatic Parking qA113 to. be the first fully Brake for Heavy ''..'automatic parking brake to Vehicles be incorporated in the design of a vehicle, the American Brake-a-Matic attachment locks the brakes full on after the vehicle has been brought to rest. The system is operated electrically and comprises a governor or pressure switch and solenoid valve, and is wired on
an independent circuit. While the vehicle is in motion the pressure switch keeps the circuit open, even with the accelerator pedal released and brakes applied. As soon as the vehicle is stationary, the solenoid valve becomes energized and the brakes are automatically applied. Points in Production TO anyone who has not
of Large Pneumatic A during recent years visited Tyres . . . an important tyre factory, some of the modern methods employed must come as quite a revelation. For example, whereas in the older days, tyre casings, particularly in the larger factories, were built on rounded carriers, now the casing is flat crosswise, and is forced into its more normal shape by high pressure in the stout " inner " tube which accompanies it to the vulcanizing mould. With the bigger tyres, insertion of the tubes is a combination of strength, skill and power. Some casings are placed on the bed of a hydraulic press. The tube is then drawn up in to the hollow ram of this and as the ram is lowered on to the tyre the tube is forced into it, the shaping being assisted by the ram pressure, as well as that within the tube. With still larger casings the operator controls what might be termed a " punching " ram which forces the tube into the tyre while it is in the mould, using a
succession of pushes or punches This ram and its cylinder are suspended above the mould and can be moved to any position.
Simple Conveyor A T the splendidly equipped System for Building "Thornycroft works at Thornycroft Engines Basingstoke, an interesting conveyor system has been installed in the new engine shop. The normal arrangement in production is for units or vehicles to travel slowly past stores of parts arranged at the sides of the track, these being constantly replenished The Thornycroft way is to arrange the stores at one end of the track and put batches of parts on to it as they are required, so that they are brought to the engines. The latter are, however, mounted in cradles carried on rollers, so that they can be easily manceuvred by hand, although they remain more or less stationary while being erected.
