Title: Improvements in or relating to methods of producing tanning materials
IPC: C14C3/24
Filed: 1943-02-19
Abstract: A tanning agent is obtained by chlorinating sulphite cellulose waste by using about 10-30 per cent chlorine based on the organic substances present, and treating with alkali during or after chlorination to eliminate the organically combined chlorine.  The sulpho lignic acid or salts thereof present in the waste lye are chlorinated and the chlorine replaced by hydroxyl groups. Preliminary treatment of the waste lye may include fermentation and distillation to remove alcohol, removal of sulphurous acid, and treatment with soda or sodium sulphide to precipitate calcium and iron.  The purified solution may be concentrated and treated with chlorine and caustic soda, as described in example 1. Alternatively, chlorine and an alkaline earth hydroxide, such as calcium hydroxide, may be added to the dilute solution, as in example 2, forming a precipitate of the calcium salt of a tannic acid.  This precipitate is treated with sulphuric or oxalic acid or alkaline salts thereof, and the calcium sulphate or oxalate removed.  In a further modification described in example 3, the calcium salt of the tannic acid is reacted with hydrochloric acid and sodium chloride to precipitate the free tannic acid which may be separated and re-dissolved in water.

Filed: 1937-02-02
Abstract: 476,141. Regulating. SOC. ANON. SOLEX. Feb. 2, 1937, No. 3060. Convention date, Nov. 4, 1936. [Class 7 (vi)] [Also in Group XXVI] In a liquid-fuel injection engine having an air throttle automatically opened by a spring against the action of the engine suction, the means for manually controlling the fuel supply is connected to the throttle spring so as to maintain the correct proportion of fuel and air. Fig. 1 shows one form, in which liquid fuel is supplied to injectors by a pump 2 controlled by a rod 14 connected by linkwork 16, 17 to a hand lever 12, which is also con. nected by a rod 13 to a spring 9 tending to open an unbalanced air throttle 5 in the inlet to a turbo-compressor 4. A screw adjustment 18 may be provided at the connection of the link 17 to the lever 12. In a modification, the pump 2 injects liquid fuel past a needle valve into the inlet pipe between the throttle 5 and the compressor, the needle valve being connected to the link 17. Fig. 3 shows a further modification having means for reducing the fuel supply when the density of the air falls below a certain value. The spring 9 is connected to a diaphragm 28 which is also acted on by a spring 33 tending to extend the spring 9. One side of the diaphragm is connected at 34 to the air-inlet pipe before the throttle 5, and the other side by pipes 35, 36 to a Venturi 37 on the other side of the throttle. The two sides of the diaphragm are further connected together by a pipe 31 with a restriction 32, and a valve 38 in the connection 35, 36 is closed by the throttle when this is fully opened due to a decrease in the density of the air. The suction in the Venturi 37 then displaces the diaphragm to the left, thereby diminishing the fuel supply by movement of the lever 12 and the connection 17, either directly or through a servomotor. The compressor may be arranged in front of the throttle, or be omitted altogether. Specification 443,933 is referred to.

Abstract: 397,766. Starting compression-ignition engines. INTERNATIONAL HARVESTER CO. OF GREAT BRITAIN, Ltd., 259, City Road, London.-(International Harvester Co. ; 606, South Michigan Avenue, Chicago, U.S.A.) Feb. 1, 1933, No. 3111. [Classes 7 (ii) and 7 (v).] In a compression-ignition oil engine, started as a petrol engine by reducing the compressionratio, means are provided for restoring the normal compression-ratio after a predetermined number of revolutions have been made. The compression-ratio is reduced by lowering a valve 63, Fig. 5, and so opening an auxiliary combustion chamber 60 containing a sparking-plug ; the valve has sealing means comprising a seat 70 on the valve guide which moves with the valve against a spring 73, operation being caused by a cam 51 on a shaft 50<1> and a floating lever 76 which is held against the cam by a second spring 79, the necessary lost motion being thus provided. The shaft 50<1> is rotated by a worm 49, Fig. 6, on a shaft 45, which at the same time, through a link 85, rotates a valve 91 and so opens a passage for a supply of combustible mixture from a carburetter 94 and closes the main air supply passage. The shaft 45 is rotated by a handle 46, Fig. 2, against a spring 42 and held in the starting position by the engagement of a dog 47 with a catch 48 on a pivoted lever 39. The other end 40 of this lever passes through a slot 35 in a disc 33 to the position shown and the disc is slightly rotated to keep the parts in engagement. The disc is mounted on a shaft 24 which is driven through a dog clutch 25, capable of taking a small amount of torque only, from a shaft 23 rotated through reduction gearing from the engine crank-shaft. After a predetermined number of revolutions have been made the slot 35 will come into line with the end 40 and the dog 47 will be released and the shaft 45 rotated by the spring 42. The valve 63 is thus closed, and the valve 91 rotated to admit the main air ; provision is also made for cutting out the spark ignition and turning on the heavy oil fuel supply to the nozzle 57.
