Title: A process for the purification of oils and fats
IPC: C11B3/06
Filed: 1921-06-22
Abstract: In the purification of liquid oils and fats by the addition of a soluble salt in conjunction with a base which precipitates the free fatty acids as insoluble soaps, small quantities of solid fatty acids are also added to increase the consistency of the precipitated soap. Suitable fatty acids are those obtained from tallow and palm oil. According to one example, 10,000 parts of cottonseed oil are mixed with 50 parts of fatty acids from tallow, 160 parts of milk of lime, and 20 parts of common salt.  After stirring at the ordinary temperature the mixture is freed from water by heating under reduced pressure, the temperature is raised to 85-90 DEG  C., and the mass is filtered or centrifuged.  Other examples describe the treatment of sesame oil and soya-bean oil.

Title: Photography
IPC: G03C8/08
Filed: 1966-04-19
Abstract: 1,141,925. Photographic processes and materials. HORIZONS Inc. April 19, 1966 [July 2, 1965], No. 17183/66. Heading G2C. A photographic material comprises at least three superposed layers, a first layer containing a photo-polymerizable composition, a second layer containing one reaction component and a third layer containing the other reaction component, the second and third layers being separated by at least one-vapour-permeable barrier layer and one reaction component being an organic halogen compound which is sufficiently volatile on heating to diffuse into the layer containing the other reaction component. The specified photo-polymerizable layer is acrylamide with methylene bisacrylamide and ferric salt and a hydro-peroxide as catalyst whereas carbon tetra-bromide and 3, 6-bis dimethyl-amino-9-dimethylaminophenyl xanthene are specified as reaction components. Negative images are produced by having the photopolymerizable layer as top layer with the volatile organic halogen layer just below so that on imagewise exposure to tight, the photo-polymerizable becomes vapour-impermeable in the exposed areas. Subsequent heating will volatilize the organic halogen which can only escape through the barrier layer below into the impermeabilized areas but can escape in both directions in the still permeable, unexposed areas of the photo-polymerizable layer so that a negative image is produced. A positive image is produced when the photo-polymerizable layer is placed between the layers containing the reactants so that on exposure to light the exposed areas of the photo-polymerizable layer polymerize and act as a barrier to the organic halogen when it is volatilized on subsequent heating and thus a positive image is produced.

Title: Improvements relating to primary batteries
IPC: H01M6/04
Filed: 1935-06-17
Abstract: 449,587. Batteries. NATIONAL CARBON CO., Inc., 30, East 42nd Street, New York, U.S.A. June 17, 1935, No. 17360. Convention date, Aug. 17, 1934. [Class 53] A primary battery is provided with a material such as lime in contact with the electrolyte to remove from solution the waste products produced by the action of the battery. With the lime is mixed a porous substance such as asbestos, cellulose fluff, paper or cotton flock to enable the electrolyte to penetrate into the lime. The lime and porous substance may be mixed with a binder and made into the form of a briquette which may be perforated, roughened or indented to increase the area in contact with the electrolyte. The binder may consist of a salt normally containing water of crystallization such as alum or sodium sulphate. The salt is dehydrated and mixed with the lime and cellulose and acts as a binder as it takes up water. Caustic soda may also be used as a binder and is mixed in finely divided form with a mixture of lime, cellulose and water. Fig. 1 shows a battery of the kind depolarized by air and comprising two cells each of which has a carbon electrode 14 and two zinc electrodes 15. A solid mass of caustic soda 16 surrounds the carbon electrode and dissolves to form the electrolyte when water is introduced into the cell. Additional masses of caustic soda 19, 20 may be provided, the mass 19 being supported by a wire 21 which serves as an indicator for the correct level of the solution in the cell. When the cell is to be activated water is poured in till it reaches the top of a chamber 22 formed in the lid of the cell. As the masses 19, 20, 21 dissolve the volume of the liquid decreases till it stands at about the level of the wire 21. The upper part of the carbon electrode is protected by a depending portion 17 of the lid. The mixture of lime and cellulose &c. is contained in a porous wrapping 23 which may have a constriction formed by a binding 30 to provide a channel for the electrolyte. The bag 23 may rest on the bottom of the cell as shown in Fig. 1 or it may be raised on a perforated metal support 25 as shown in Fig. 4, or on separate supports 28, 29 extending from the bottom of the cell as shown in Fig. 3 which also shows the mixture of lime and cellulose and binder pressed into a briquette 27. A slopping position is given to the briquette to prevent air from being trapped beneath. The briquette may be placed at the top of the battery, for example round the wire 21 in place of the mass of caustic soda 19. Alternatively the mass 16 may consist of a mixture of caustic soda, lime and cellulose or the like. Instead of lime other materials for precipitating waste products may be used such as barium hydroxide, bentonite, or a zeolite.

Abstract: 447,167. Engines with two - stage compression. SEBIA SOC. D'EXPLOITATION DE BREVETS POUR L'INDUSTRIE L'AVIATION ET L'AUTOMOBILE, 20, Rue de La Rochefoucauld, Paris. June 18, 1935, No. 17560. Convention date, June 25, 1934. [Class 7 (ii)] In a multi-cylinder engine operating with two-stage compression and having an air compressor delivering into a common inlet manifold, each of the cylinders being provided with an admission valve having a delayed closing characteristic so as to transfer part of the combustible charge from one cylinder into another under the pressure of the manifold and during a substantial portion of the suction stroke of the cylinder receiving the transferred charge, the combustible mixture is formed in a closed space under a pressure equal to that in the manifold. Air is delivered by a compressor 22, through cooled or heated passages or is divided therebetween according to the setting of a control valve, to a carburetter enclosed in a hood 2 to permit it to operate at the induction manifold pressure. To prevent the pressure from collapsing the float, a tube connects the interior thereof with the space in the hood. The temperature of the mixture entering the cylinders is controlled by altering the delayed closing of the inlet valves. The engine cam shaft drives a governor which rocks a shaft in which is mounted by a quick-threaded screw the shaft carrying the cam controlling the delayed-closing of the valve, the axial displacement of the cam altering the closure of the valve. An adjustable rod 28 connects the carburetter throttle control lever 25 to the control lever 26 of the inlet valve to the compressor and the pressure may be controlled by coupling a second inlet valve 19 to a piston 32 in a cylinder 31 open to the induction manifold, the piston being urged to oppose the manifold pressure by a spring 33 operating between the piston and an abutment tube 38 which engages a lever 34 connected at its other end to the throttle connecting rod 28, the pressure necessary to close the valve 19 thus increasing with wider throttle openings.
