Title: Improved process for producing filaments, threads and the like cellulose products from viscose
IPC: D01F2/10
Filed: 1938-11-25
Abstract: 521,727. Artificial filaments; sulphonium compounds; wetting agents. VEREINIGTE GLANZSTOFF FABRIKEN AKT.-GES. Nov. 25, 1938, No. 34322. Convention date, Dec. 2, 1937. [Classes 2 (ii), 2 (iii), and 15 (ii)] To facilitate spinning and to prevent the formation of incrustations in the spinnerets, there is added to the viscose spinning solution a small amount of a cation-active sulphonium condensation product obtained by the action in substantial absence of water of organic sulphides selected from the group consisting of dialkyl sulphides, diaryl sulphides and alkyl-aryl sulphides of the general formula R,SR  2 , on halogenated constituents of petroleum having more than eight carbon atoms. The halogenated hydrocarbon may be obtained from crude petroleum, kerosene, gasoline, lubricating oil, pasty petrolatum, liquid petrolatum, or paraffin wax. The coagulating bath may be a solution of sulphuric acid with a zinc salt, and it may also contain a sulphonium compound similar to that contained in the spinning solution. Petroleum constituents which belong to the methane, polymethylene, or benzene series may be used. The hydrocarbons may be dissolved in carbon tetrachloride or other solvent and chlorine or bromine may then be passed through the solution. The reaction may be carried out in presence of iron or other catalyst or in the presence of ultra-violet rays, or in presence of silica gel, active carbon, nickel or pumice, or other absorbent. Chlorination may be effected in presence of iodine as catalyst. Disulphides which may be used include dimethyl, diethyl, dibutyl, dibenzyl, diphenyl, and methyl-benzyl sulphide. The sulphonium compounds are obtained by heating the sulphides with the halogenated hydrocarbons preferably under reflux. The two components may first be dissolved in benzene, ether, toluene, or other solvent. The products may be used in the crude state or after purification. The sulphonium compound may be a chloride, bromide, iodide, or fluoride. It may be converted in the viscose solution into a free sulphonium base. The presence of the sulphonium compound in the viscose may lead to the production of filaments of softer lustre.

Patent GB-1062580-A (GB)
Title: Metal powders
Inventor: WEST DE WITT HENRY
IPC: B22F9/30
Filed: 1964-08-19
Abstract: Non-spherical nickel powder substantially free from carbon is produced by decomposing nickel carbonyl vapour in the substantial absence of water vapour in the hot free space of a decomposer having nitrided steel inner surfaces.  The steel surfaces are preferably nitrided by heating them to a high temperature (e.g. 500 DEG C.) in the presence of ammonia which may be passed alone into the decomposer or passed with the carbonyl in a previous operation with an optional addition of oxygen.  In the latter case the ammonia concentration should not exceed 0.2% by volume in the presence of oxygen since this would cause spherical particles to be produced.

Patent GB-762057-A (GB)
Title: Improvements in or relating to electronic magnetic recording systems
IPC: G11B5/00
Filed: 1954-11-30
Abstract: 762,057. Electric digital-data storage apparatus; recording-apparatus. GENERAL ELECTRIC CO. Nov. 30, 1954 [Nov. 30, 1953], No. 34736/54. Classes 106 (1) and 106 (4). Electronic apparatus for enabling the recording and playing back of data indicative signals on a moving magnetic storage medium comprises a plurality of control heads 13 associated with the storage medium and arranged in a matrix of row and columns, the control heads each including a coil 63 and a magnetic flux directing element 65 for providing a flux path between the coil and the storage medium, together with switching means 15 for selecting a particular row and switching means 17 for selecting a particular column so that the control head at the inter-section of the selected row and column is energized and further switching means 19 for enabling the selected head to be used either to record data on to the magnetic storage medium or to read data from the magnetic storage medium. As shown, the matrix comprises only two rows A, B, and two columns a, b, and is particularly adapted for digital data. For recording data the read/record control switch 19 is set to connect a high potential (180 V.) source 107 to the row selecting switch. The row and column selecting switches 15, 17 are then appropriately set to select the desired head, say head Aa (top left). This results in a high voltage being applied to all the centre taps of the coils in the selected row and hence via rectifiers 69 to all the triodes 33, two of which are associated with each column, and in a gate opening potential being applied to two " and " gates 25, 27, associated with column a. A data signal to be recorded, either a " plus " generated by a device 21 of a " minus " generated by a device 23, then passes through gate 25 or gate 27, firing one of the tubes 33 and causing a current to flow in one direction or the other through the selected head, thus recording either a " plus " or a " minus " on the moving magnetic medium which may for example be a drum. To read data, a particular head is selected in the same way, but the read/record switch 19 is set to connect a low potential (10 V.) to the switch 15. This voltage is insufficient to permit tubes 33 to conduct but sufficient to unblock the right-hand rectifiers 69, each of which is earthed via a resistance 111. The column selecting switch also opens an " and " read gate 41 associated with the column a so that any signal developed across resistor 111, as a result of current flow in the selected head created by reading data on the magnetic medium, is passed via gate 41 to a read amplifier 45. The switches 15, 17 and 19 may be electronic trigger circuits.

Title: Improvements in gas-meters
IPC: G01F15/04
Filed: 1937-12-15
Abstract: 492,082. Counting apparatus. BORMANN, O. Dec. 15, 1937, No. 34780. Convention date, Dec. 15, 1936. [Class 106 (i)] In a gas meter comprising a measuring element which drives one counter when running forwards and another when running backwards, and also including means for correcting the indications for variation of pressure or similar condition of the gas, a rotational direction rectifier 9, is arranged in the driving connection between the measuring element and the correction mechanism. The rectifier comprises two ratchet wheels 4 and 5 mounted on the driving shaft 24, from the measuring element, wheel 4 being rigidly connected to the shaft and wheel 5 being driven in reverse direction by bevel gears 2 and 3. The shaft 10 connected to the correction mechanism carries ratchets 12 and 13 engaging wheels 4 and 5, so that the shaft 10 is always driven in the same direction when shaft 24 turns in either direction. The correction mechanism comprises a drum 26 driving a roller 27 which is carried on an arm 28 turned about a pivot 35 by means responsive to the pressure of the gas. A cam or wheel 27 reciprocates a frame 40 through levers 34 and 37. When the direction of rotation of shaft 24 changes the casing of the rectifier 9 swings and the pivot of frame 40 is shifted by a lever connection. Thus rod 43 driving one counter is reciprocated when shaft 24 runs one way and shaft 44 to the other counter is reciprocated when the direction is reversed.
