Points Raised in ConTHE discussion which fol nection with Rubber lowed the paper on the Bonding . . welding of rubber to metal, read by Mr. A. J. Hirst before the 1.R.T E., and reported elsewhere in this issue, was lively. One suggestion was that it would be more economical to fit chromium-plated shackle pins in place of rubber-bonded units. Our view is that the greasing costs would soon exceed the higher initial outlay involved by the latter. Another question was as to the advantage gained by a rubber-bonded engine mounting unit compared with a plain rubber pad or ring. Mr Hirst said that rubber bonding not only absorbed torsional vibrations but had the inherent advantage of reducing longitudinal stresses. This would be apparent on the movement of controls attached to engine, gearbox and clutch. Bondedrubber bushes were also almost free from fungus growth in tropical climates. The problem was to obtain rubber resistant to oil but resilient.

Road Transport Can THE chairman of the Do More to Help the National Conference c f Railways . . Road Transport Clearing
Houses,. in a statement issued by that body, calls attention to the grave warnings given recently by the Parliamentary Secretary to the Ministry .of Transport and by Sir Stafford Cripps on the actual and anticipated difficulties of maintaining the flow of goods transport during the winter. The Government is urging a quicker turn-round of railway wagons, and it appears that it is adopting a policy of diverting more traffic to the road. The Conference is of the opinion, however, that there is little evidence that much of this diversion has occurred, with the exception of open-cast coal, and that the haulage industry is able and willing to carry a great deal more than at present. With additional loading and unloading facilities at week-ends, the effective capacity of road vehicles could be much increased, especially on longer journeys. A Heavy Charge 1111ZECAUSE he could not, Imposed for a Light I–' alone, restart the engine of Nap. . his large oil-engined lorry once
it had been stopped, a Yorkshire lorry driver left it idling while he recently snatched " forty winks" at Buckden at midnight. Because the engine's noise was disturbing their sleep, nearby residents telephoned to the police, and in due course the driver received a summons to appear at Court to answer a charge of causing unnecessary noise. "It is the first time in over 15 years of lorry driving that I have heard of such a charge," he indignantly commented in a letter to the Court. "If you convict me you will have to charge every lorry driver going through Buckden." Whether every lorry driver
proceeding through the town will in due course grace the dock is mere conjecture, but certainly factual was the £2 fine imposed on this particular Mender.
Rayon Tyres with 1N some of the new American Weftiess Bodies and tyres with rayon-cord con Nylon Cushions struction. twin layers of rubber-coated cords are placed just under the tread They are claimed to prevent bruising impacts from reaching the main body, and
reduce the danger of tread separation Another interesting factor is that the natural curl of the rayon is eliminated by electronic processing, so that the cords can be laid parallel and flat in a weftless-type construction which reduces friction
