Patent GB-909403-A (GB)
Title: Improvements relating to systems for producing deformations in the surface of a deformable medium
IPC: H04N5/74
Filed: 1959-01-06
Abstract: 909,403. Television; light modulating. GENERAL ELECTRIC CO. Jan. 6, 1959 [Jan. 13, 1958], No. 485/59. Addition to 909,401. Class 40 (3). In a television receiver in which the deformation set up in a deformable medium 15 when scanned by an electron beam 13 velocity modulated by television signals are utilized to modulate light from a source 23 and thus to project a television picture on to a viewing screen 35 the medium 15 has the property of decreasing in volume resistivity with decreasing thickness. This prevents the scanned area of the medium from decreasing to zero thickness when the force due to the changes (relative to the conducting coating 21) deposited by the scanning beam overcomes the surface tensions from the excess of the medium outside the scanned area since the decrease in volume resistivity results in a decreased time constant for the passage of leakage current from 15 to the coating 21 and an equilibrium condition is then reached in which the force due to the changes is equal to that due to the surface tension. Such a medium should have a volume resistivity that varies within the range of 10<SP>14</SP> to 10<SP>11</SP> ohms per c.c. and an average resistivity at the equilibrium condition of 10<SP>11</SP> ohms per c.c. At the working temperature range of 25‹ to 100‹ C. the viscosity should be in the range 100 to 50,000 centistokes. Suitable materials are (1) butyl esters of methyl- #-carboxyethylisiloxanes, (2) bees wax, and (3) methyl silicone fluids which may contain up to about 5% of phenyl silicones.

Abstract: 509,248. Hydraulic presses. BLISS CO., E. W. Jan. 7, 1938, No. 538. Convention date, Jan. 21, 1937. [Class 69 (ii)] ' In a hydraulic press having a surge valve for admitting slack liquid to the main work chamber during rapid advance of the ram, the valve is hydraulically closed, and the arrangement comprises a valve-closing chamber and a balance chamber which latter is in constant communication with the main work chamber. The surge valve 20, Fig. 1, is closed by the introduction of pressure liquid through pipe 28 into the valve-closing chamber 15b which is of small extent so that the valve may be closed rapidly; a balance chamber 15d communicates through bores 43 with the main work chamber 16, so that when the valve is closed it is subject to an excess of pressure acting to maintain it closed. When the valve has closed, liquid from the closing-chamber 15b opens a check-valve 33 in the valve 20 and passes to the work chamber 16 to effect the pressing stroke. The valve is opened by pressure admitted by pipe 30. Alternatively, Fig. 3, the valve may be spring- opened. The passage 43 in the surge valve contains a valve arrangement whereby free flow from space 16 to space 15d is permitted allowing quick closing of the valve, but flow from space 15d to space 16 is restricted whereby the opening movement of the valve is cushioned. Other modifications are described. Specification 509,925 is referred to.

Title: Manufacture of alkali metal chlorites starting from chlorine dioxide
Inventor: SOLVAY CIE
IPC: C01B11/10
Filed: 1947-01-07
Abstract: 644,309. Electrolytic manufacture of alkalimetal chlorites. SOLVAY & CIE. Jan. 7, 1947, Nos. 567 and 568. Convention dates, Jan. 31, 1946 and July 19, 1946. [Class 41] An electrolytic process of manufacture of alkali-metal chlorites comprises reaction between an alkali metal hydroxide and chlorous acid, the acid being obtained by cathodic reduction of chlorine dioxide and caused to react with the hydroxide in proximity to the cathode of the electrolyte cell where the chlorous acid has been formed. In modifications of the invention the reaction is between chlorine dioxide and an alkali-metal amalgam or an alkali-metal salt. In the arrangement shown in Fig. 1, sodium hydroxide is introduced into the anode compartment A and passed through a diaphragm D into the cathode compartment C to which chlorine dioxide is supplied through a cathode K in the form of a diffuser of graphite or other porous material. Oxygen is freed at the anode. In the arrangement shown in Fig. 3, an alkali metal amalgam is supplied to the bottom of a compartment A which is separated by a diaphragm D from a compartment C supplied with chlorine dioxide through a porous member K. This member is connected by a conductor E to the amalgam, the cell becoming a voltaic cell in which the amalgam is decomposed and alkali-metal chlorite is produced. In the arrangement shown in Fig. 5, the cathode solution is circulated by a pump M between the cathode compartment C of an electrolytic cell and a scrubber B on which the solution is saturated with chlorine dioxide. Brine enters the anode compartment A at the bottom and overflows at the top. Part of the catholyte is removed through a pipe P and the chlorine dioxide therein is separated from alkali-metal salts by known means, for example evaporation or crystallization. In the process described the catholyte may be supplied with hydrogen peroxide or acid to ensure that no chlorate is formed.
