Patent GB-837479-A (GB)
Title: Improvements in or relating to apparatus for recording two or more different variables
IPC: G01N27/00
Filed: 1957-02-12
Abstract: 837,479. Recording-apparatus. CENTRAL ELECTRICITY GENERATING BOARD, CUMMINGS, W. G., and REDFEARN, M. W. March 11, 1958 [Feb. 12, 1957], No. 4820/57. Class 106 (4). [Also in Group XXXVI] Apparatus for recording the concentration of sulphur dioxide in air, in which air is passed upwardly through the countercurrent absorption column 9 described in Specification 837,477, down which a reagent solution flows and in which a measurement is made of a characteristic of the reagent solution after the reaction to produce an electric signal representative of the amount of the reaction, has a pen moved transversely over a constant-speed chart by a milliammeter responsive to the electric signal, which can be interrupted or altered periodically to displace the pen in one direction to represent the rate of flow of the air and in the other direction to represent the rate of flow of the reagent solution flow. The electric signal may be derived from the conductivity of the sulphuric acid derived by passing the air through hydrogen peroxide by apparatus described in Specification 837,476 or it may be derived photo-electrically in accordance with the colour change caused by passing the air through a starch iodine reagent as described in Specification 837,478, a modification of which is disclosed in the present Specification. The rate of flow of air is measured by a domestic type gas meter 17 which operates as switch S8 each time a predetermined quantity of air passes, which switch S8 shunts the milliammeter, causing the pen to move to a predetermined value of low current, b (Fig. 2). The rate of flow of reagent is measured by repeatedly filling a vessel 20 having a siphon 22 to waste and a float-operated switch S6 which disconnects the conductivity cell 13 connected to the output of the absorption column and switches in another 25 sensitive to the conductivity of the supply of reagent, which would be constant if the temperature were constant. The apparatus is housed in a thermostatically-controlled chamber 15, but if the temperature varies the change in conductivity will be a measure thereof, recorded by the pen periodically with the rate of flow of the reagent, a (Fig. 2). A false zero can be set for this latter record to avoid any confusion with the main record.

Title: Processes for the manufacture of leather and leather products tanned by zinc sulphurcompositions
IPC: C14C3/04
Filed: 1955-02-18
Abstract: 778,153. Tanning hides. AMERICAN ZINC, LEAD & SMELTING CO. Feb. 18, 1955 [May 13, 1954], No. 4891/55. Class 76. Hides are tanned by impregnating them with a soluble sulfide or hydrosulphide capable of producing SH ions such as K 2 S, NaSH, Ba(SH) 2 , Ca(SH) 2 , Na 2 S or (NH 4 ) 2 S, and then impregnating the hides with an aqueous solution of a zinc salt which reacts with the sulfide or hydrosulphide to fix a zinc compound in the hides. The zinc salts employed are preferably the chloride or sulfate or an ammoniacal solution thereof or a basic salt of the chloride and sulfate. The hides may subsequently be further tanned, for example, with formaldehyde, syntan or chromium salts. According to examples : (I) bated hide was treated in a ball mill with a solution of sodium hydrosulphide and common salt, then removed and ball-milled with a solution containing zinc sulfate and common salt. The hide was finally washed and milled with a solution containing an anionic sulfonated oil and common salt (III) an aqueous solution of sodium hydrosulphide and calcium chloride was employed to treat calf skin which, after impregnation and draining, was treated with a zinc sulphate solution containing common salt and finally with an aqueous emulsion of an anionic sulfonated oil. A white leather containing 6.4 per cent of zinc was obtained. (V) a hide was treated with sodium hydrosulphide and salt as before and after washing was milled with a zinc sulphate solution containing common salt. After soaking overnight, a solution of chromium sulphate in water was added and the soaking continued. The hide was finally milled with an aqueous solution of an anionic sulfonated oil. (VI) a hide was treated with sodium hydrosulphide and zinc sulphate as before and a 40 per cent solution of formaldehyde was added to the zinc sulphate solution towards the end of the process. The hide was then washed and treated with an anionic sulfonated oil as before. If additional tanning is required it can be effected at the end of the tanning during the oiling step.

Title: Improved shuttle valve for fluid flow systems
Inventor: HOROVITZ MARCUS
IPC: F02M37/00
Filed: 1957-02-13
Abstract: 827,765. Fuel supply systems. NEW PRODUCTS CORPORATION. Feb. 13, 1957, No. 4920/57. Class 7(3) [Also in Group XXIX] In a fuel supply system comprising a plurality of tanks 25...27 containing individually operable pumps 30...32, the delivery pipes 21...23 of which are interconnected and connected to the carburetter supply pipe 20, the interconnections between the pipes 21...23 consist of shuttle valves 28, 29, containing a pressureoperated shuttle 56, Fig. 2, which opens the delivery pipe of the pump delivering fuel and closes the remaining delivery pipes. The pumps 30...32 are controlled individually by switches 39...41 connected to the ignition circuit and the delivery pipes 22, 23, are connected by the valve 28 to a pipe 24 which is led with pipe 21 to the valve 29 having its outlet 20 connected to the carburetter. Each valve 28, 29 comprises inlets 50, 51, Fig. 2, and a floating shuttle 56 which in its end positions connects one inlet to the outlet 49 and closes the other inlet by resting against seats 63, 64, and in its intermediate position connects both inlets to the outlet 49. Hence if, as in Fig. 1, the engine is operating on tank 27 with pumps 30, 31 inoperative, the pressure in pipe 23 moves the shuttle 56 of valve 28 to close pipe 22 and connect pipe 23 to the pipe 24 which similarly becomes connected through valve 28 to the pipe 20. Shortly before tank 27 is emptied switch 40 is closed to operate pump 31 and the increase in pressure in pipe 22 moves the shuttle of valve 28 to an intermediate position in which both pipes 22, 23, are connected to pipe 24 until tank 27 is emptied when the shuttle moves to seat 64, Fig. 2, to close the pipe 23. A similar action occurs in valve 29 when tank 26 is exhausted and pump 30 is brought into operation. When the engine is at rest one or other of the tanks is always in communication with the pipe 20, permiting the float chamber 11 to drain.

Abstract: 1528163 Hardening photographic layers AGFA-GEVAERT 23 Jan 1976 [10 Feb 1975] 5653/75 Heading C3H [Also in Division G2] In a process for the hardening of a proteinaceous layer there is applied over such a layer a composition comprising a non-polymeric fast-acting, carboxyl group-activating hardening agent in combination with a film-forming, hydrophilic, polymeric, fast-acting hardening agent carrying one or more carboxyl groupactivating substituents. Non-polymeric hardeners include carbamoyl and carbamoyloxypyridinium compounds, carbodiimides, isoxazolium salts and dihydroquinoline derivatives. The polymeric hardening agent possibly forms a continuous matrix from which the non- polymer hardener diffuses into the protein layer. The polymer chains carry as substituents the same carboxyl-activating groups as those in the non-polymeric compounds. The polymeric hardening agents can contain groups of the Formula (I) where A represents a chemical bond or a group of the formula -CO À O-, -CONH-, or in which R<SP>1</SP> and R<SP>11</SP> represent a methyl or ethyl group, R<SP>111</SP> represents an alkylene group of 1 to 4 carbon atoms, X- represents an anion, R<SP>1</SP> represents hydrogen or methyl, R<SP>2</SP> and R<SP>3</SP> represent alkyl of 1 to 4 carbon atoms and R<SP>4</SP> represents phenylene or an alkylene group of 1 to 4 carbon atoms. Other recurring units can be present, e.g. from styrene, vinyltoluene, alkyl acrylates and methacrylates. Suitable polymers can be prepared by reacting a dialkylamino carbodiimide compound with a polymer containing reactive chlorine substituents.
