Abstract: 163,293. HnÚvkovsky, S. April 21, 1921. Electric stores.-An electric cooking-device .comprises a number of heating elements T1 - -T5 arranged, side by side in series with switches So, S1, S2 so that one or two of the elements may be cut out of the circuit. Curved mirrors are arranged behind the elements to reflect the downwardly radiated heat upwards through the openings between the elements. Each heating element is formed by iron wire coiled round wooden blocks d, which by their carbonization prevent oxidation of the wire, and is enclosed by inter-engaging U-shaped metal casings P1, P2, the wire being insulated from the casings at the bottom and the sides by a layer of insulating clay k. An air space v is maintained between the wire and the upper face of the casing. A plastic mass of carbon, litharge, and kaolin mixed with sulphuric acid is pressed between the wires, this mass having a conductivity in a cold condition of one-fifth of the conductivity in a hot condition.

Abstract: 503,886. Selective solvent extraction of oils. TEXACO DEVELOPMENT CORPORATION. April 20, 1938, No. 11861. Convention date, June 18, 1937. [Class 91] Hydrocarbon oils, especially residuums containing asphalt, are fractionated and freed from asphalt by extraction with a solvent mixture consisting of furfural and a mixture of o- and p-chlorphenol containing 60 to 70 per cent of the para compound. The p-chlorphenol is a good solvent for asphaltic and dark-coloured constituents. Extraction may be effected by batch or countercurrent method, and in the presence of a diluent such as liquefied propane. The oil may first be freed from hard asphalt by treating with propane at 120‹ F. The solvent mixture preferably contains 25 to 75 per cent of furfural. After extraction the layers are separated, and the raffinate layer after removal of solvent consists of a light coloured lubricating oil of low Conradson carbon value.
