Title: Improvements in electric discharge tubes
IPC: H01J17/22
Filed: 1934-08-13
Abstract: 430,460. Discharge devices. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. Aug. 13, 1934, No. 23336. Convention date, Sept. 1, 1933. [Class 39 (i)] A vapour-filled discharge tube, such as a rectifier or a relay, is provided with an incandescent cathode which is located in the immediate vicinity of the vapour-generating liquid but is separated therefrom by an apertured wall in such a way that the vapour produced escapes substantially through a part of the wall which closely surrounds the cathode. Mercury 2, Fig. 1, in the bottom of a rectifier, is separated from an oxide cathode 3 by a container 4 which is provided with apertures 10 and is welded to an annular shell 5 provided with apertures 6. The cathode leading - in wires are sealed into the tube and the container 4 by means of tubes 9. Condensate flows back to the pool through a space between the shell 5 and the tube. In another form, the cathode 3, Fig. 2, is located in an apertured container 13 the bottom of which is immersed in mercury in a cup-shaped cavity 12. The container is supported centrally by means of a cylinder 6 which rests in the cavity on wire supported rollers 19. The diameter of the cylinder 6 may be substantially reduced at one or two parts to facilitate the return of the condensate. The cathode supply wires are seated in the tube at the end 15 and are surrounded by steatite tubes 14 which, by means of cross-members 17, are registered with respect to a wire 16 welded to the container 13. Wires 18 secure the container 13 to the tubes 14. The container 13 may be used as a starting electrode and, for this purpose the wire 16 is connected to a supply wire 20. The tube is provided with three anodes which are located in separate arms. The anode supply wires are covered with steatite tubes 23 and the rear-end of each anode is surrounded by a cylindrical screen 24 of metal gauze to facilitate heat radiation and to minimize back discharges. All metal parts which contact with mercury are formed of iron or chrome-iron or of copper or zinc which are preferably coated with chromium. The leading-in wires may be sealed by means of chrome-iron discs the edges of which are sealed to the glass envelope. The tube may have a large cooling surface or a condensation space may be inserted between the anode and cathode and be connected to the cathode space through narrow arms. A vapour pressure of at least 0À1 mm. may be obtained in the container 13 and the filling may comprise a rare gas.

Abstract: 922,149. Superconductor circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 7, 1959 [Oct. 7, 1958], No. 23354/59. Class 40 (9). [Also in Group XIX] A binary adder circuit for deriving a signal on output terminal S (representing 1) or S (representing 0) signifying the units digit on adding three input signals X or #X, Y or Y, Z or Z on correspondingly marked terminals, comprises a superconductive plate 10 apertured so as to form a network of parallel circuits between battery 14 and the output terminals S, S. A second plate 12 derives a signal on terminal C or C representing the carry digit. The signals energize windings X1, X2, &c., #X1 &c . . . . Z1 &c., #Z1 &c. and drives resistive the superconducting paths linked with the windings. The circuits and the windings of plate 10 are arranged so as to produce an output on terminal S in accordance with the logical equation: The circuits and windings of plate 12 produce an output on terminal C in accordance with the equation: The adder is reset after each operation by means of a signal R on terminals R. A similar adder comprises networks 10, 12 of strips of superconductive material deposited on a glass plate 20, Fig. 2, by an evaporation process. Control conductors X, Y, Z, X, Y, Z and a reset conductor R are deposited by a similar process. The shaded parts of the strips are of soft superconductive material such as tin which goes resistive in response to a small control current and the unshaded parts which may be of lead are hard and do not go resistive in response to the control currents used. The hard parts of the strips are deposited first, using a mask 22, Fig. 2A. The soft parts are deposited using a mask 24, Fig. 2B, and the whole assembly is covered with an insulating layer of silicon monoxide which is also deposited by an evaporation process. Finally the reset and input conductors R, X, Y, Z, #X, #Y, #Z are deposited using a mask 26, Fig. 2c. In a modification, the networks 10, 12 are made entirely of tin which is soft, and parts of the strips are made narrow to concentrate the current at points when control is to be exercised. Specification 862,178 is referred to.

Title: Improvements in processes for manufacturing viscose with a view to the manufacture of artificial silk and like products not liable to lose their resistance by contact with water
IPC: D01F2/08
Filed: 1922-08-31
Abstract: Viscose giving products, such as artificial silk, resistant to water, is prepared from an alkali cellulose in which in all the operations involved in its manufacture, excessive hydration of the cellulose is avoided by the employment of a low temperature such as 0 DEG  C., that is to say, this temperature is maintained during the soaking of the cellulose, the pressing to remove the excess of caustic alkali solution, the subsequent pulping operation, and the final mercerizing, which may occupy one to several days; afterwards slight hydration of the cellulose is permitted to take place by storage for one or more days at a temperature not exceeding 15 DEG  C.; thereafter the mass is converted into xanthogenate.  As regards the other details of the process, the cellulose, preferably cotton or woodpulp, is soaked in caustic soda solution of 20-25 DEG  B. strength, then pressed until the mass contains 0.3-0.5 parts of caustic soda to one part of cellulose; the prepared soda cellulose is treated with 10-15 per cent of carbon disulphide, calculated on the weight of cellulose taken, while maintaining a temperature not exceeding 20 DEG  C., and the resulting xanthogenate dissolved in caustic soda solution to give a viscose containing 5-8 per cent of cellulose and 15-25 per cent of caustic soda.  Such a viscose may be spun immediately, or it may be matured for one to three weeks at a temperature not exceeding 10 DEG  C.  Specifications 135,205 and 178,152 are referred to.

Title: Production of oxygenated hydrocarbons
IPC: C07B35/04
Filed: 1953-09-02
Abstract: Oxygen-containing organic compounds, including acetic and other acids, aldehydes and ketones, are produced by non-catalytic vapour phase oxidation of hydrocarbons comprising passing a vaporous mixture comprising the hydrocarbon and less than 25 mol. per cent of oxygen based on the hydrocarbon under superatmospheric pressure through a heating zone in which the mixture is heated to an elevated temperature below that at which uncontrolled reaction ensues and then through a reaction zone in which, following an induction period and without further heating, the oxidation reaction proceeds at a rapid rate with a rise in temperature, and reducing the length of the induction period by introducing into said mixture an organic peroxide which decomposes to liberate free radicals at temperatures attained during the induction period.  Hydrocarbons specified are ethane, propane, butane, pentane, ethylene, propene, butene and pentene. Mixtures of hydrocarbons may be used.  Preferably the hydrocarbon is mixed with between 2 and 25 mol. per cent of oxygen in the form of air, oxygen enriched air or pure oxygen, at a pressure of 20-300 pounds p.s.i.g. and heated to a temperature in the range from 500 DEG to 700 DEG  F.  Suitable peroxides have a half-life not exceeding 0.5 sec. at reaction temperature, alkyl peroxides or hydroperoxides including t-butyl hydroperoxide, ditertiary butyl peroxide, peracetic acid, acetyl peroxide and benzoyl peroxide being preferred.  The peroxides are preferably employed in concentrations of between 0.05 to 2.0 volume per cent based on the total volume of the reaction mixture.  When all the available oxygen has been utilized, the reaction mixture is cooled, e.g. by quenching with an aqueous medium, and the products are recovered. The unreacted residue may be recycled through the reaction, or passed through a hydrocarbon recovery system to separate useful hydrocarbons from diluents and inert gases.  In Examples (1) and (2), ditertiary butyl peroxide is added to a mixture of n-butane and air, which is heated in a furnace to 570-575 DEG  F. and passed into a reaction line wherein the oxidation goes to completion; the mixture is then quenched with an aqueous medium and the products are recovered therefrom while the residue is recycled.
