Title: Improvements in and relating to cathode ray tubes
IPC: H01J29/32
Filed: 1953-10-02
Abstract: 781,911. Cathode-ray tubes. PHILCO CORPORATION. Oct. 2, 1953 [Oct. 3, 1952], No. 27076/53. Class 39(1). A cathode-ray tube has a target electrode having a surface layer of secondary electron emissive material and a base layer which has regions of different electrical resistance to electron flow whereby different regions of the target are differently responsive to the impingement of the electron beam to emit secondary electrons. A theory is given of the control of the secondary emission characteristics of the surface layer by the underlying electrical resistance. Some electrons penetrate to the base layer. It is believed that the resistance normal to the surface is of greater importance than the transverse resistance. The varying resistances may be obtained by varying the underlying resistivity or by varying the thickness of the base layer. The invention has application to colour television receiver tubes where strips of different secondary emissive properties provide indexing signals. Red, green and blue phosphors 29, 30 and 31 are provided in groups of three on a uniformly conducting base layer 28 which is provided on an insulating support 27. Spaces between phosphors 29 and 30, and 29 and 31 are filled with unactivated phosphor material, e.g. willemite. A secondary emissive layer 34, e.g. MgO, Au, Ag, or W, is deposited over the whole target area, and, in the spaces between phosphors 30 and 31 contacts the conductive layer 28, e.g. stannic oxide to provide the indexing strips. MgO is deposited by first covering the target with a solution of polyvinyl alcohol and ammonium dichromate in water, and, after draining and drying, spraying with a solution of magnesium powder and water. The solution of polyvinyl alcohol mixed with magnesium powder is hardened by exposure to light and the soluble deposit is washed off. Conductive strips 28 may be provided only in the indexing regions. Specifications 713,908, 743,409, 745,353 and 749,118 [Group XL(b)] are referred to.

Title: Method of and apparatus for supervising the running of automatic thread winding machines
IPC: B65H54/22
Filed: 1951-11-27
Abstract: 740,687. Winding-machine control means. REINERS, W. Nov. 27, 1951 [Nov. 29, 1950], No. 27785/51. Addition to 740,685. Classes 120 (2) and 120 (3). The method of supervising the running of winding-machines disclosed in the parent Specification is modified in that an increased tension is temporarily applied to the thread after completion of the knot to check the efficiency of the thread-tying device. As shown the disc 35 which revolves once during a threadtying operation as explained in the parent Specification allows, after completion of the knot, the lever 125, 126 to pivot at 127 and thus engage contacts 128 and 136. This completes an electric circuit containing electromagnets 135 and 124. Electromagnet 135 pivots the lever 139 and 140 thus increasing the tension on the thread between supports 142 and 143. At the same time electromagnet 124 increases the pressure between the package 3 and the driving drum 2. A variable resistance 132 allows the amount of increased tension to be adjusted. Should the knot fail due to the increased tension the feeler 7 will cause a thread-tying failure to be registered in the manner explained in the parent Specification.

Abstract: 1,214,493. Oxidation of unsaturated cycloaliphatic hydrocarbons. IMPERIAL CHEMICAL INDUSTRIES Ltd. 21 May, 1968 [16 June, 1967], No. 27818/67. Heading C2C. The invention relates to a process for oxidizing an unsaturated cycloaliphatic hydrocarbon which comprises treating the hydrocarbon in liquid phase with a gas mixture containing molecular oxygen and a catalytic amount of ozone, i.e. an amount such that the oxidation produced exceeds that which would be affected by the oxygen and the ozone acting independently at the temperature of operation. Preferably the amount of ozone is from 1 to 6% of that theoretically needed to effect the oxidation if ozone were the only oxidizing agent and the proportion of ozone relative to oxygen in the gas mixture is from 0À05 to 10%. A metallic compound, e.g. a manganese or cobalt salt may be present as an oxidation catalyst. An inert diluent such as acetic or propionic acid may be used to increase the amount of oxidation and the process may be carried out in the presence of an alkaline substance, particularly magnesium oxide or sodium carbonate in order to reduce tha formation of high boiling by-products. Examples are given of the oxidation of cyclohexene, -octene, -dodecene and cyclooctadiene.
