Abstract: 644,279. Rotary pumps. TRICO PRODUCTS CORPORATION. March 5, 1948, No. 15428/49. Convention date, March 8, 1947. Divided out of 644,209, [Group XXIII] [Class 110(ii)] An air pump 13 of the outwardly-sliding vane type is driven by an electric motor when the suction in a pipeline 15 is insufficient for external use, as in operating a windscreen-wiper, for instance. A check valve 39 is closed when the pump in operating. The electric circuit of the driving motor is automatically closed when the pressure in the byepass 14, 15 exceeds a certain figure. A switch 19 comprises a plate sucked down from two contacts by the suction in the byepass 15. If this suction is deficient, a spring forces up the plate, which bridges the contacts and starts up the driving motor for the pump. Normally the byepass 14, 15 is open to the suction of an internal-combustion engine, for instance, and the pump is stationary. The system in which the pump is used is described in Specification 644.209, [Group XXIII].

Abstract: 871,718. Heat insulation; refrigerated vehicles. MINIKAY Ltd. May 16, 1958 [May 20, 1957], No. 15914/57. Classes 29 and: 64(2) Passages formed by channels 15 in the walls of an insulated vehicle communicate with pores and voids in the insulation. which may consist of several layers 20, 21 of. expanded rubber or asbestos, and the passages are continuously or periodically connected to a drying element to remove or exclude moisture. The layer 21 is an asbestos sheet next to the vehicle inner lining 17 and the channels 15, in the wall shown, are formed in the layer 20 adjacent to the sheet 21. The channels extend vertically in the walls and transversely in the roof 14 and floor. They intercommunicate at the upper and lower corners of the room and, if the vehicle is cooled continuously by refrigeration, the drying element is a finned cooling pipe 27, between an expansion valve and a first eutectic plate, in metal casing 29 with which communicate openings 30 from the nearby channel ends. Drain pipes 33, which may have a liquid seal, conduct the moisture away when the pipe 27 is defrosted at intervals. To give a progressive temperature rise to aid air circulation, the channels 15 in the wall shown are near the cold inner lining 17 but, proceding round the floor, opposing wall and roof 14, the channels are progressively further from the linning. In vehicles without continuous refrigeration, but with eutectic plates, the passages may be equidistant from the lining and, at diagonally opposite corners, the passages open into metal ducts by which the passages are connected to an air-circulating system including a refrigeration evaporator element for drying. The drying is done each time the eutectic plates are cooled at a depot. In vehicles with no cooling apparatus nor plates, the metal ducts are at the lower corners for connection, periodically to a warm air drying system including silica gel or activated alumina.
