Title: Improvements in or relating to the production of cyanogen chloride
IPC: C01C3/00
Filed: 1968-02-16
Abstract: 1,219,183. Cyanogen chloride. AGRIPAT S.A. 16 Feb., 1968 [17 Feb., 1967], No. 7598/68. Heading C1A. Cyanogen chloride is prepared by passing water downwardly through a packed scrubbing column and then in a falling film through a reactor section and passing gaseous chlorine upwardly through a lower packed stripping section to the falling film reactor section and then through the scrubbing column and flowing gaseous hydrogen cyanide into the column at the upper end of the falling film. The temperature in the falling film section of the column is controlled by extracting a substantial part of the heat of reaction directly from the falling film section of the column. The relative proportions of water, chlorine and hydrogen cyanide are adjusted so as to produce hydrochloric acid at the bottom of the column at a concentration of between 10% and 23% by weight. Gaseous cyanogen chloride flows up through the scrubber and is washed by the downflowing water. The hydrochloric acid is saturated with chlorine and cyanogen chloride which may be stripped from the acid to improve the efficiency of the process. The hydrochloric acid formed is sufficiently concentrated to be a useful by-product.

Abstract: 348,276. Feeding webs. DICKHAUT, C. A., 120, North 5th Avenue, Highlam Park, New Brunswick, New Jersey, U.S.A. March 10, 1930, No. 7744. [Class 100 (i).] Apparatus for transversely guiding a travelling web of cloth, paper, &c., comprises two parallel straight rollers 1, 2, Figs. 3 and 4, under and over which the web passes and which are spaced apart on a frame 11 which is movable about a central pivot 15 under the control of a feeler device engaging the edge of the web. The frame 11 is connected by a rod 32 to a diaphragm 24 forming one side of a chamber 23<1> which is connected to a vacuum pump 26, Fig. 3, and, by a pipe 27, to a nipple 56, Fig. 7, having a valve seat 54 controlled by a valve 53 carried by a lever 48 provided with a pair of spaced-apart fingers 72, 73 engaging the edge of the web. An adjustable spring 35 on the rod 32 acts in opposition to the vacuum in the chamber 231 and the parts are so set that normally the valve 53 admits an amount of air to the chamber 231 such that the rollers 1, 2 are at right-angles to the run of the web. If the web deviates to either side, the corresponding movement of the fingers 72, 73 causes the valve to admit more or less air to the chamber 23<1> resulting in a movement of the frame 11 in a direction to restore the web to its correct path. A single feeler finger may be employed but the pair of fingers 72, 73 prevents actuation of the control by the passage of a small irregularity such as the torn portion 75, Fig. 3. To prevent excessive vacuum in the chamber 23<1>, the end 36 of the rod 32 may extend into the chamber and be caused to actuate a release valve 37.

Title: A process for the preparation of dammar resin especially for use in cellulose ester lacquers
IPC: C09F1/00
Filed: 1928-03-15
Abstract: 309,701. Potts, H. E., (Scheiber, J., and Firma L. Blumer Chemische Fabrik). March 15,1928. Natural resins.-Dammar resin is prepared, especially for use in cellulose ester lacquers, by extracting it with a hot solvent for the dammarolic acid and alpha-dammar resene, the #-dammar resene being substantially undissolved and unswollen. The treatment may be effected by exposing the resin to hot liquid solvent or to the heated solvent vapours. Suitable solvents are certain alcohols, esters, ketones, &c. such as butyl alcohol or ethyl acetate, and mixtures which may include a limited proportion of solvent for the #-resene, such as aromatic or petroleum hydrocarbons, chlorinated hydrocarbons or carbon disulphide may be used. Ethyl alcohol alone is unsuitable. When the vapour method is employed using solvent mixtures, the mixtures must have a constant boiling point. Mixtures of alcohols with hydrocarbons, with or without water such as carbon disulphide-alcohol, benzene - alcohol, toluene - alcohol, benzenealcohol-water, and toluene-alcohol-water, constant boiling mixtures may be used. In examples (1) The vapour from 33 Kgs of alcohol and 68 kgs. of benzene, or, in the presence of water. 30 Kgs of alcohol, 50 Kgs of benzene, and 15 Kgs of toluene are allowed to act on 100 Kgs of dammar placed in a filter cloth in a perforated vessel. A concentrated solution of dammarolic acid and the alpha-resene forms at the bottom of the apparatus, the #-resene and impurities remaining in the filter cloth. (2) Dammar is treated with etliyl acetate at raised temperature. (3 Dammar is mixed with benzene and alcohol and heated to the boiling point of the mixture. On cooling, the #-resene separates out with the impurities.

Title: Improvements in record carriers for mechanical sound recording
Filed: 1938-03-15
Abstract: 496,530. Recording sound. RETERSON HOLDING SOC. ANON. March 15, 1938, No. 8046. Convention date, March 17, 1937. Drawings to Specification. [Class 40 (ii)] A carrier for the mechanical recording of sound comprises an orientated material derived from viscose, the micelles of which are orientated in the direction of recording. A strip of regenerated cellulose, preferably obtained from cellulose sodium xanthate is orientated by exerting a tensile force, in the direction in which recording is to take place, after the solution has been coagulated and before the xanthate is decomposed. This produces a resistance to breaking which is greater in the direction of orientation than at rightangles to this direction. For mechanical recording and reproduction the carrier may comprise a ribbon formed of two or more layers of orientated regenerated cellulose bound together by a gelatinous emulsion. The top layer then serves for the cutting of the record while the lower layer serves as its support. In order to enable it to follow the line of orientation, the cutter is allowed a small amount of side play. For mechanical recording with optical reproduction, the carrier consists of a number of layers one of which is black or coloured, so as to act as a screen for the reproducing light beam and which is cut through by the cutter during the recording.

Abstract: 698,085. Roller mills. BUHLER, GEB. April 12, 1950 [April 14, 1949], No. 9026/50. Class 59 [Also in Groups XXIX and XXX] A regulator for roller grinding mills comprises a piston 11, Fig. 2, for moving a roller 2 relative to a roller 3, and a piston 18 for controlling a feed gate 15 at the cutlet of a feed hopper 14. A device 22 detecting the amount of material flowing into the hopper actuates a valve 20<SP>1</SP> controlling an exhaust port 18<SP>1</SP> in the piston 18. Pressure fluid is supplied by a pump 23 through lines 25, 34, chamber 26, line 29 to the space above the piston, and when the valve 20 is urged downwardly, pressure bulids up in the space and the chamber 26 to move a piston valve 27 to connect the line 25 to the cylinder 12 containing piston 11. The dimensions of piston 18 and spring 24 are so arranged that the piston 11 moves before the piston 18. If the pressure fluid is compressed air, a whistle 37 is connected to the return line 35 and when the valve 27 is urged to its lower position due to lack of material in the hopper, an audible warning is given. The feed rollers 4, 5 are moved into and out of gear mechanically in dependance on the position of the movable grinding roller. A cock 29a in the line 29, when closed, causes the grinding rollers to be engaged and feed rollers to be moved into gear whereby the hopper may be completely emptied through the narrow gap between the gate 15 and roller 4, which gap is present when the gate is closed. In another arrangement, Fig. 3 (not shown), a pivoted flap detects the inflow of material and actuates the gate through an arm and also operates a leak-off valve controlling the valve 27.
