Abstract: 348,856. Surface carburetters. SMITH, F. H., 10, Mayo Road, Sherwood Rise, Nottingham. April 26, 1930, No. 12915. Convention date, April 29, 1929. [Class 7 (iii).] Liquid fuel is fed to a rotating perforated disc by capillary action at low engine speeds, and by a combined frictional and centrifugal action at high speeds, the liquid film being penetrated by air to form a rich mixture. A rotatable spindle 7 carries a gauze or like disc 8, and a member 83 covered with felt or the like. Around the member 83 is a sleeve 89 with internal helical groove, the sleeve being mounted on a flange 90 in the float-chamber 82. Fuel is supplied to this chamber through duct 93, filter 94, and duct 95 controlled by needle 96 actuated by a float 91 through a lever 97. At low speeds, fuel is fed mainly by capillary action of the felt or the like on member 83 whilst at high speeds centrifugal action forces fuel up the internal groove of member 89. A bevelled ring 115 ensures spreading of the fuel over the disc, and the fuel flow may be controlled by a disc 8a which may have, associated therewith, one or more washers of felt. The sleeve 89 may be adjustable. The fuel film is burst by air and the rich mixture is delivered through a slit or apertures 9 controlled by a triangular opening 105 in a tubular throttle valve 104. This valve is adapted to be rotated by an arm 107 on a spindle 109 which also carries a ported disc valve 114 for controlling entry of air through passage 113. At low speeds, only small holes in the inner end of the throttle register with the apertures 9. In a modification, the member 83 may have strips of absorbent material inserted in longitudinal grooves therein. In a further modification, the fuel-raising member may consist of an inverted hollow cone the interior being lined with absorbent material and the apex being perforated to allow fuel to enter.

Title: Process for the refining of vegetable and animal oils and fats and more particularly for the recovery of solvents used in such refining process
IPC: G09F11/23
Filed: 1934-04-30
Abstract: 430,381. Purifying oils and fats. METALLGES. AKT.-GES., 45, Bockenheimer Anlage, Frankfort-on-Main, Germany. April 30, 1934, No. 13038. Convention date, Feb. 15. [A Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 29, 1934.] [Class 91] When refining vegetable or animal fats or oils by the process involving saponification of the fatty acids by dilute alkali, &c., and subsequent extraction of the soap with dilute alcohol or an aqueous alcoholic saline solution, excessive dilution of the alcohol in the later distillation step for its recovery is avoided by the evaporation of the fatty acid soap solution prior to its extraction, to such an extent that the concentration of the alcohol in the distillate is equal to or higher than that of the aqueous alcohol originally employed for extracting the soap. In carrying out the process the following alternative procedures may be adopted: (1) the neutralized oil may be subjected to vacuum drying to cause the separation of the soap in the form of flakes, the soap being then separated from the oil by extraction with alcohol ; (2) the soap flakes obtained as in method (1) above are first separated from the oil by settling, centrifuging, filtering, &c., and afterwards treated alone with the alcoholic solvent; (3) or the soap stock is separated from the oil by settling, centrifuging, &c., and then subjected to vacuum drying, followed by alcohol extraction. Drying of the soap stock facilitates the separation of the mucins, lecithins &c. To obviate difficulties such as foaming, &c., when distilling off the last portions of alcohol from the soap paste, it is convenient to add, prior to the distillation, sulphuric or other acid to liberate the fatty acids. The fatty acids recovered in the process may be hydrogenated and distilled, any traces of oil being decomposed by splitting ; or they may be esterified with glycerol. In some cases an emulsified layer may be formed during the solution of the fatty acid soap, such layer containing neutral oil, a portion of the alcoholic soap solution, and the bulk of the mucins, &c. This layer is collected separately and is worked up by extraction with aqueous alcohol or aqueous alcoholic saline solution to remove the soap, the resulting solution being used for the treatment of fresh fatty acid soap ; the oil emulsion that remains, is treated with dilute acid to separate the oil. If the fat or oil to be refined is subjected to a preliminary refining with acids, it is preferred to perform the saponification immediately after the refining process, the salts produced during the neutralization facilitating the subsequent stages of the process.
