IN the past, iodine-type light units have been restricted to fog or spotlights or four-headlamp systems. Now a major breakthrough is claimed by Philips Electrical Ltd., who have developed a two-filament iodine-type headlamp in their research laboratories in Holland. It is said that it will be some time before this type of lamp is on the market.

LST it is accepted that the dual air system required on plated vehicles is in fact two completely separate systems other than the one eompresser, there is a limit to this duplication. Obviously the actual stopping mechanism at the road wheels must also serve both systems, but the dual safety system does extend as far as the wheel chambers. Although these chambers still appear as a single body, they are designed to operate as a dual unit, and are arranged internally for this purpose. The Clayton-Dewandre dual safety system includes a triple-diaphragm wheel brake chamber, which answers the requirement, but the terms dual and triple may call for a little explanation for those meeting plated equipment for the first time. The triple-diaphragm chamber has the same features of design as the single-diaphragm type, but does in fact embody three diaphragms—two operating and one acting as an isolator.
