Are Our Windscreen A NOTABLE feature of Wipers Suitable for "many of the vehicles disOverseas ? . . . . played at the Geneva Show
was the large, well-made and powerful windscreen wipers. Apart from covering a great area of the screen, these are not liable to be choked and stopped by snow. In Britain, of course, we do not experience many snowstorms except in certain parts of the country, but we have noted that the average small wiper sometimes proves inefficient under such wintry conditions. Incidentally, abroad much use is made of heaters which prevent snow turning to ice on the windscreens Sometimes such heaters are carried round to corner windows.
Rubber Development A PARTICULARLY interProvides Controlled "esting development by the Internal Heat . . , Goodyear Tyre and Rubber Co. (Gt. Britain), Ltd., is a new rubber derivative which reverses the normal insulating qualities of rubber, transforming it into a material which, whilst permitting the passage . of A24 current, provides sufficient resistance to develop heat. Known as Pliotherm, this new product provides heat, merely by the turning of a switch. It is claimed that this has great potentialities for the interior heating of vehicles of all types, and with a suitable modification of the current, the temperature can be kept within the limits required. Panels of Pliotherm are cheap to install, can be made in a wide range of colours, are easily combined with wood or plastic wall coverings, and are protected by an outer coat of ordinary rubber.

After use much of the ink can be saved' and the screen is thoroughly cleaned. CLERESTORY roofs require that the vision of passengers should not be obstructed by such fittings as parcel racks. in this connection we recently noted a coach with a Swiss body, in which the racks were formed in curved transparent plastic. Of course, to carry the matter still further, it would seem to be necessary to have parcels and their contents also transparent which might, at times, prove embarrassing

Some Foreign Vehicles A WHEEL chock is art Still Equipped With 1—taccessory seldom if ever Chocks ..... found as standard on a British vehicle unless it be some special type such,as one designed for winching. Abroad, however, some vehicles carry these useful devices as a matter of course. Some Satners, for example, have mounted at one side of the chassis frame a neat steel container into which his a handled chock; which, incidentally, has spikes at one side so triat it can grip the ground. These chocks are particularly useful when vehicles may be required to halt
for some time on hills, and where slipping of the brake lever, or interference with it during the absence of the driver, might cause an accident.
