Abstract: An automobile temperature control system has a motor chamber on which a secondary cell or a fuel cell is mounted for driving wheels by a motor and a cabin and controlling a temperature of portions of the automobile. The temperature control system includes at least one catalytic heater and a fuel tank. The catalyst heater generates heat when an oxidizing gas and fuel from the fuel tank are supplied to the catalyst. At least part of the gas supplied to the catalyst and heated by the generated heat is subjected to circulative supply to the catalyst. The temperature of the portion of the automobile is controlled by using heat generated by the catalytic heater. As a result, a system is provided that efficiently controls the temperature of a portion of the automobile so that performance deterioration is prevented and comfortable running is realized even in a cold region.

Abstract: An air conditioning system for conditioning air in a passenger compartment of a motor vehicle includes a secondary cell or a fuel cell for driving wheels with a motor. The air conditioning system further includes a catalyst heater, an air conditioning duct, and an air conditioning fan. The catalyst heater generates heat by supplying a fuel and an oxidizing gas to the catalyst. The air conditioning duct is connected with an intake port and a blowing port. The air conditioning fan is provided in the air conditioning duct so that the air in the passenger compartment can circulate. The air in the air conditioning duct is conditioned by utilization of the heat generated with the catalyst heater so that the air in the passenger compartment is conditioned.

Abstract: Fine spherical particles of cured silicone elastomer can be prepared by spray-drying an aqueous emulsion of a curable organopolysiloxane composition having a particle diameter not exceeding 20 .mu.m. The organopolysiloxane composition comprises preferably an organopolysiloxane having silicon-bonded vinyl groups, an organohydrogenpolysiloxane having silicon-bonded hydrogen atoms and a platinum catalyst so that curing of the composition may take place in the emulsion before spray-drying or in the course of spray-drying by the addition reaction between the silicon-bonded vinyl groups and the silicon-bonded hydrogen atoms.

Abstract: So-called addition-type curable organopolysiloxane compositions curable by the hydrosilation reaction between vinyl groups of a dimethylpolysiloxane and hydrogen atoms directly bonded to the silicon atoms in a methylhydrogenpolysiloxane in the presence of a platinum catalyst can be imparted with a greatly increased pot life to have improved workability when the composition is admixed with a halogen- or alkoxy-substituted olefinic organic compound such as allyl halides, 1,3- and 2,3-dihalogenopropenes, 2-alkyl-3-halogenopropenes, 1,3- and 1,4-dihalogenobutenes-2 and alkyl allyl ethers as a moderator of the crosslinking reaction without any adverse effect on the curability of the composition.
