366,454. Spray and surface carburetters ; vaporizers. ELECTROLUX, Ltd., 153, Regent Street, London.-(Assignees o f Platen - Munters Refrigerating System Aktiebolag ; 2, Norrmalmstorg, Stockholm.) July 31, 1930, No. 23159. Convention date, Aug. 2, 1929. Void [Published under Sect. 91 of the Acts]. [Class 7 (iii).] In a process of refrigeration the heat required to vaporize the fuel in the mixture passing from the carburetter 13 to the cylinders 10 of an internal-combustion engine is abstracted from a fluid circulating through a condenser pipe coil 17 in a heat-insulated duct 16 and a vaporizer coil 40 in the refrigerator 18. In a modification, the duct 16 may be disposed in the refrigerator. In another arrangement, preheated air flows through tubes 14, Fig. 2, and a valved-duct into a heat-insulated vessel containing benzine &c., the saturated air passing through a liquid separator 21 to the induction pipe surrounding the tubes 14, and the heat required for the vaporization of the benzine being abstracted from the fluid passing through the pipe coil 17. In a further modification, the fuel from a tank 25, Fig. 3, is drawn into a vaporizing chamber 23 in a refrigerator 30 by a pump 24 driven by the engine and discharged into a duct 27 having a valved air inlet pipe 26.
