Patent GB-916153-A (GB)
Title: Improvements relating to selector circuits
Inventor: LOBELLE MARCEL JULES ODILON
IPC: H03K3/45
Filed: 1960-05-25
Abstract: 916,153. Pulse distributers. M.L. AVIATION CO. Ltd. July 17, 1961 [May 25, 1960], No. 18493/60. Class 40 (3). [Also in Group XXI]  A device for energizing a number of conductors in sequence comprises a magnetic storage device associated with each conductor after the first, the magnetic storage devices being so arranged as to respond to successive input pulses so that they produce output pulses in the desired sequence.  As applied to bombslip mechanisms 1-4, positive input pulses fed to terminal 11 release the mechanisms 1-4 in sequence. The ferrite rings 19, 36, 41 are initially set to positive remanence so that the first pulse operates mechanism 1, contact 6 opening to isolate mechanism 1 from subsequent pulses. This first pulse charges condenser 20. At the cessation of the pulse, discharge of the condenser sets ring 19 to a state of negative remanence. The second pulse charges over ring 19 to induce an output pulse in winding 21 which is amplified by transistors 23-25 so as to energize the second bomb slip 2. Feedback between 24 and 23 lengthens the amplified pulse. This pulse charges condenser 37 so that ring 36 is then set for the reception of the third pulse and so on. As each bomb is slipped so a light connected to the corresponding terminal 70-73 is extinguished. When all bombs are gone, lamps 14, 15 are extinguished also. If the circuit is used for a further set of bombs it may be reset automatically by the pulse on the last conductor 10 charging condenser 64, the subsequent discharge resetting the rings through windings 51-53. Alternatively they may be reset by application of a pulse at terminal 54. A pulse at 58 or 59 will reset 52 and 53 or 53 alone. In the first of these two cases bombs 1 and 2 will then slip together, in the second, bombs 1-3.

Abstract: 823,962. Suede-like agglutinated-fibre materials; laminates; coated fabrics. DU PONT DE NEMOURS & CO., E. I. June 18, 1956 [July 27, 1955], No. 18855/56. Drawings to Specification. Class 140. A sheet material comprises at least one base layer of matted structural fibres and a surface layer of fibres of length 5 to 15 mils., the base and surface layers and the fibres thereof being bonded together by an extensible polymeric binder and some or all of the fibres in the surface layer being raised to give a suede-like finish. The sheet material is formed by hot-pressing the fibrous layers which are either interleaved with sheets of thermoplastic binder or are impregnated therewith, and the surface layer containing the short fibres is abraded to remove the binder and so give a suede finish. Suitable binders are vinyl and vinylidene polymers and copolymers (including synthetic rubbers and polythene) which may be halogenated, polyesters, polyamides, and polyurethanes, and may be used in conjunction with plasticizers. Natural or man-made fibres may be used, e.g. a blend of rayon and nylon, but preferably the binder used is different from the fibre and that used in the top layer may be different from that in the other layers, e.g. to provide a hard top layer. Colour may be imparted to the top layer either by including dyes or pigments in the binder or by dyeing the fibres before impregnating them with binder or a binder and colour coating may be applied, and an outer " depth " binder coating containing less plasticizer than in the other layers may be applied. The material may be made porous either by stretching it or by swelling the fibres as by a water dip to rupture the bond between fibres and binder or by extracting solvent-soluble pore-forming fibres, e.g. cellulose acetate, included in the sheet material. Examples are given of the production of multilayer porous sheets using neoprene as binder and nylon fibres in all the layers or polyethylene terephthalate in the top fibrous layer only. Specifications 553,733, [Group IV], 711,279, 711,280, [both in Group IX], 737,137, 751,017, 763,604 and 782,952 are referred to.

Abstract: 335,543. Elkington, H. D., (Naamlooze Vennootschap de Bataafsche Petroleum Maatschappij, (formerly De Bataafsche Petroleum Maatschappij) . June 24, 1929. Hydrogenation, destructive.-In the destructive hydrogenation of oxygen-containing carbonaceous material, such as coal, brown coal or lignite, cellulose, tars, pitches or petroleum residues, or mixtures of solid carbonaceous material, with liquid oxygen, containing products such as tars, phenols, cresols, &c., the materials are first treated with carbon monoxide or gases containing carbon monoxide, at elevated temperatures and preferably under pressure, thereby removing most of the oxygen prior to subjecting the resultant material to a second and separate treatment in the presence of the hydrogen or of gases consisting substantially of hydrogen. Known catalysts may be employed in both stages and the gases containing carbon monoxide may be water gas or producer gas. Water present in the initial material or formed therefrom during the process may react with the carbon monoxide to form hydrogen which may partially hydrogenate the material; water may be added to bring about this result. When treating coal, lignite and similar material, a mixture of hydrogen and carbon monoxide is preferred but tars and other liquid oxygen-containing material may be treated with carbon monoxide alone in the first stage. Volatile products are removed before the material is destructively hydrogenated. The process may be applied to mixtures of coal &c. with such oxygen containing substances as normally require only a one stage treatment, e.g. a mixture of brown coal and phenols, cresols &c., valuable cyclic hydrocarbons being produced in the first stage. In an example, brown coal was heated in an autoclave with a catalyst consisting of a mixture of simultaneouly precipitated ferric and aluminium oxides together with water and a mixture of hydrogen and carbon monoxide in equal quantities, the amount of the gases being such as to give an initial pressure of 100 kilograms per square centimeter. The temperature was gradually raised to 460‹ C. whereupon the heating was stopped and the pressure released after the temperature had fallen to 300‹ C. The volatile products were condensed and the residue subjected to destructive hydrogenation. Specification 257,256 is referred to.
