Title: Curative specifics containing sulphonated derivatives of santalene or caryophyllene
IPC: A61K31/00
Filed: 1931-10-05
Abstract: Sulphonates of the sesquiterpenes santalene or caryophyllene are prepared by adding concentrated sulphuric acid to a mixture of the hydrocarbon with acetic anhydride.  Water is added to the mixture after reaction and the whole neutralized by alkali and the oil layer removed.  The alkaline sulphonate is extracted from the aqueous solution with chloroform, the chloroform evaporated, the residue redissolved in water and extracted with ether to remove any remaining oil, and the aqueous solution evaporated to dryness.  The Specification as open to inspection under Sect. 91 relates also to the use of esters of santalol, such as acetates, oleates, valerianates and salicylates, and the mono-santallic esters of succinic, phthalic and camphoric acids, and similar esters of caryophyllenic alcohol; of the alkaline salts and esters of the acids found in the resinous portion of oil of copaive, viz., illurinic, b -metacopaivic, p-copaivic, and homoparacopaivic acids; and of derivatives of the hydrocarbons santene and caryophyllene formed by introduction into the nucleus or side chain of groups such as nitro, nitrous, amine, or hydroxyl.  The method of manufacture of the foregoing compounds is not described.  The various derivatives may be administered in water or oil or insoluble derivatives may be rendered soluble in water by association with the sulphonates or salicylates. The prior use of suspension of sandal wood oil in water, or of solutions of the oil in peanut oil is referred to.  This subject-matter does not appear in the Specification as accepted.ALSO:Sulphonates of the sesquiterpenes santalene and caryophyllene are prepared for use in medicine by injection or local application.

Abstract: 848,353. Carburetters. AUSTIN MOTOR CO. Ltd., and WEANING, H. J. Sept. 10, 1958 [Sept. 4, 1957], No. 27910/57. Class 7(3). A fuel economizer for a petrol engine comprises two sources of petrol supply one of high octane petrol and the other of an inferior regular or commercial grade, the supplies being under control of a valve 29 which is responsive to the suction in the induction manifold, the arrangement being such that when the engine is on full load or full throttle at low speed the spring loading on the valve maintains it in a position in which the supply 22 of high octane petrol is open whilst when the suction in the induction manifold increases to a value which will overcome the spring loading on the valve the latter moves to a position in which it closes the high octane petrol supply and opens up the supply 23 of inferior grade petrol. The supply passages 22, 23 each lead to a float chamber (not shown). In a modification the valve 29 is controlled by two diaphragms, one acted on by the pressure in the pipe 38 and the other by the pressure in the pipe 43 and the non-return valves 39, 44 are omitted. In another modification the valve 29 has a position in which it cuts off both petrol supplies under the action of the high suction which prevails in the induction pipe under over-run conditions. The invention is shown applied to a carburetter of the controllable jet type.

Abstract: 449,750. Colour photography and kinematography. BREWSTER, P. D., 28, Gillespie Avenue, Fair Haven. New Jersey, U.S.A. Sept. 29, 1934, No. 27965. [Glass 98 (ii)] An additional component subtractive colour image-series is formed in a gelatin layer on a film, on a side which already bears a different component colour image-series, by printing in register with the existing series from a colourrecord imbibition matrix film with a printing medium which is converted by chemical action within the gelatin into a colourless substantially transparent and insoluble dyemordant, and treating the dye-mordant imageseries with the appropriate dye. The additional image-series may be printed in the same gelatin layer as the existing series, or in gelatin layer. coated thereon. The method may be applied to two- or three-colour films. All the imageseries on the film may be produced by the same method ; or the additional series may be formed on either side of a film on which one or more other component image-series have been produced by any desired process, such as that described in Specification 449,679. The printing medium for the additional series may be a solution of a metallic salt as of silver, copper, uranium, lead, tin, thorium, vanadium. iron, nickel, or cobalt, an aqueous solution of silver nitrate or copper sulphate, or a solution of cuprous chloride in hydrochloric acid being instanced ; and the salt images are converted after printing into dye mordant by a reagent already present in the gelatin print layer or subsequently applied thereto, such as an alkaline halide, ferrocyanide, or thiocyanate, or an easilv hydrolized acid such as hydriodic or hydrobromic acid. Alternatively, the reagent may be used as the printing medium, and the metallic salt may be included in the print layer or be subsequently applied thereto. Malachite green and auramine are referred to as basic dyes. To prevent the existing image-series from being affected by the addition of another series, the dye used for the first series may be laked before printing the additional series as by sodium acetate, aluminium sulphate, chromium sulphate, or copper salts, with or without tannin, and cuprous chloride is preferably used as printing medium, associated in solution with ammonium chloride, hydrochloric acid and potassium metabisulphite. The images forming a series may be printed from the matrix successively in apparatus with an intermittent feed plate provided with registering pins which engage the film feed perforations ; or they may be printed continuously in apparatus in which the films are pressed by a rubber roller, against a feed sprocket having registry teeth.

Abstract: 340,623. Cigarette-making machines. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(American Machine & Foundry Co. ; 511, 5th Avenue, New York, U.S.A.) Oct. 3, 1929, No. 28328/30 Divided application. [Class 130.] Cigarettes from a high-speed continuous-rod machine are delivered to a continuously moving device, which forwards them in the same direction and at not less than the speed of the cigarette rod, and from which successive cigarettes are delivered to a number of additional devices forwarding them in the same direction at reduced speed. In the apparatus shown, cigarettes from the cutting mechanism pass through a stationary tube 401 and an oscillating guide 404 from which they are discharged alternately on opposite sides of a belt 426 travelling at a slightly higher speed than the cigarette rod. The guide tube 404 is loosely engaged by an arm 405 oscillated about a shaft 406 by the stud 422 of an eccentric 421 on a shaft 416 driven through helical gears 419, 420. The guide tube 404 is adjustable axially on the tube 401 by a pinion 409 engaging a rack 407 on the tube, the shaft 406 of the pinion 409 being turned by an arm 410 carrying a spring-controlled stud 412 for engagement with holes in a disc 415. A spring 427 on the delivery end of the tube 404 presses the issuing cigarette on the fast-running belt 426, which is arched by means of a rounded bar 430, so that the cigarettes deposited on the sides of the belt 426 roll alternately on to the belts 431, 432 running at half the speed of the belt 426. A wedge-shaped block guides to the belts 431, 432 all cigarettes which have not previously rolled off the belt 426. The belt 426 runs over a pulley 433 and a driven pulley 436, the belt 431 over pulleys 447, 450 and a driven pulley, and the belt 432 over pulleys 455, 456, the pulley 455 being integral with the pulley 447 driven by the belt 431. From the belts 431, 432 the cigarettes are deflected on to transverse delivery belts 466, 467 by curved plates 464, 465 supported by bars 453, 460. Rails 478, 481, 482 prevent the cigarettes from falling off the belts 466, 467.
