Title: Improvements in or relating to processes for the treatment of beryllium ores or compounds
IPC: C22B35/00
Filed: 1937-03-01
Abstract: Beryllium is obtained from beryllium ores or compounds by heating an intimate mixture of the ore or compound and carbonaceous material in an atmosphere of nitrogen at a temperature of at least 1900 DEG  C., say 1900-2100 DEG  C., then converting the beryllium carbide so obtained into beryllium sulphide by heating the carbide at a high temperature, e.g. above 1800 DEG  C., in vapours of sulphur or a suitable sulphur compound, such as carbon bisulphide or sulphuretted hydrogen, or a mixture of several such compounds and finally subjecting the beryllium sulphide to treatment for the production of beryllium therefrom. Some beryllium nitride may also be produced in the first step. Suitable carbonaceous materials for use in the first step include low temperature carbonization coke, starch, dextrose or glucose, and a stream of nitrogen may be passed over or through the mixture.  The beryllium carbide prior to its conversion into sulphide may be purified by treatment with hot dilute hydrochloric acid followed by a washing to remove carbon and a treatment with hot concentrated sulphuric acid to remove any beryllium oxide. The beryllium sulphide may be converted into beryllium by the processes set forth in Specifications 482,467, 482,468, [Group XXXVI], 482,531, and 483,862.  Beryl may be treated by the process.ALSO:Beryllium is obtained from beryllium ores or compounds by heating an intimate mixture thereof and carbonaceous material in an atmosphere of nitrogen at a temperature of at least 1900 DEG  C., then converting the beryllium carbide so obtained into beryllium sulphide by heating the carbide at a high temperature in vapours of sulphur or a suitable sulphur compound, or a mixture of several such compounds, and finally subjecting the beryllium sulphide to treatment for the production of beryllium therefrom, for example by the processes set forth in Specifications 482,467; 482,468, [Group XXXVI], 482,531, and 483,862.

Title: Improvements in or relating to electron discharge tube arrangements
Inventor: WEBLEY REGINALD SIDNEY
IPC: H04N5/217
Filed: 1953-03-06
Abstract: 740,472. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd. March 25, 1954 [March 6, 1953], No. 6220/53. Class 40 (3). [Also in Group XL (c)] The non-uniform photo-electric sensitivity of the target of a television pick-up tube, particularly one operating with cathode-potential stabilization, is compensated by deriving control signals from a representation of the non- uniformity and employing them to control the gain of an amplifier stage transmitting signals generated by the tube. The representation is produced by flooding the tube target with light of uniform intensity, scanning the target, reproducing the generated signals on a cathode-ray tube and then photographing the fluorescent screen. The resulting transparency may be processed either positive or negative with appropriate gamma. Fig. 1 shows one arrangement in accordance with the invention in which a transparency 9 produced as described above is scanned by a flying spot scanner 10 operated in synchronism with the pick-up tube 1 by signals from a common scanning source 16, and generates signals in a photo-cell 14 representative of the non-uniformity of the tube target. These signals are then applied to control the gain of an amplifier 19 transmitting signals generated by the pick-up tube. For use in a frame sequential colour system employing a rotating filter disc 22 for colour separation, corresponding correction transparencies are produced representing the target non-uniformity for each of the colours, and these transparencies are carried by a disc 23 rotated in synchronism with disc 22. In a second embodiment arranged for colour operation, Fig. 3 (not shown), the correction transparencies for the individual colours are scanned simultaneously by separate flying spot scanners and the associated photo-cell outputs applied to control the gain of the amplifier stage through gate stages which are opened appropriately in accordance with the colour scanning sequence. It is stated that the control signals are preferably applied to control an amplifier operating at radio frequencies.

Title: Process for the hydrochlorination of butadiene-containing polymerisates
IPC: C08C19/16
Filed: 1961-02-23
Abstract: Polymers and copolymers of butadiene, containing at least 50% of the butadiene units in the 1,4-configuration, are hydrochlorinated in a rubber solvent solution with dry gaseous hydrogen chloride under a pressure of 1 to 35 atmospheres, in the presence of 0 to 100% of a Friedel-Crafts catalyst, based on the weight of the polymer, the pressure being at least 2 atmospheres when no catalyst is present. Specified monomers which may be copolymerized with the butadiene are styrene and acrylonitrile. Rubber solvents specified are benzene, alkyl aromatic compounds, chlorobenzene, carbon tetrachloride or dichloroethylene. Catalysts specified are SnCl4, TiCl4, FeCl3, AlCl3 o SbCl5.  To isolate the reaction product the solution may first be neutralized, for example with ammonia, caustic alkalis, alkaline earth oxides or neutral or acid carbonates of the alkali or alkaline earth metals, and the resulting precipitate filtered off.  The product is then obtained by precipitation with for example methanol or ethanol, by steam distillation, by distilling off the solvent in a stream of gas, or by distilling off the solvent at normal or reduced pressure. These products may contain up to 32% by weight of chlorine. They may serve for the production of adhesives and are suitable as raw materials for sheets and coating agents.

Abstract: 1,085,265. Fluid pressure brake control; hydrodynamic brakes. H. TEVES, E. A. TEVES and M. TAUSEND, [trading as ALFRED TEVES MASCHINENUND ARMATURENFABRIK K.G. Feb. 17, 1965 [March 26, 1964], No. 6818/65. Headings F2E and F2F. A motor vehicle brake pressure regulator operative with a hydro-dynamic retarder 10 comprises a mass 34 which rotates with the rotor 17 of the retarder and which, upon deceleration of the rotor, causes an axial movement operating a valve which controls the supply of fluid to a wheel brake 9. As shown in a vehicle having a line 1 from a master cylinder (not shown) which actuates, via a booster 3, front wheel brakes 6 and rear wheel brakes 9 the rotor 17 of the hydro-dynamic retarder 10 is coupled to the mass 34 through elements 32, 33 and a ball 16. During a retarding operation the mass 34 tends to run faster than the rotor causing the ball 16 to move up a cam on the mass 34 moving the element 33 and a rod 24 to the left against the action of a spring 25. This enables a spring 21 to move a ball 23 against a seat 22 interrupting fluid supply to a brake line 8 and rear wheel brakes 9. In another embodiment, Fig. 1 (not shown), the rotor 17 acts as the rotating mass and is in this case connected to the shaft 11 through an intermediate member 15, the ball 16 and the cam.
