Abstract: 1,130,206. Colour television tubes. RADIO CORP. OF AMERICA. 29 Oct., 1965 [5 Nov., 1964], No. 45996/65. Heading H1D. In manufacture of a rectangular, shadowmask, colour cathode-ray tube, the phosphor dots of the mosaic screen are laid down in an array having an axially asymmetrical distortion relative to the aperture array in the shadow mask, to compensate for asymmetrical faceplate collapse consequent upon tube evacuation, and/or for non-coincidence of the horizontal and vertical electron beam deflection centres. The screen may be produced by exposing each colour phosphor in turn with an associated photo-sensitized gel, through the shadow mask, to light from a point source passing through a refractive lens 37 having different cross-sections 40, 42 along perpendicular axes 41, 43 parallel to the major and minor axes of the rectangular screen. The lens 37 may also provide an axially symmetrical correction compensating for general axial movement of the deflection centres, or a plurality of lens may be used in series to obtain the desired effect.

Abstract: 1,019,269. Perforating sheet material. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Nov. 16, 1964 [Nov. 19, 1963], No. 46550/64. Heading B4B. A method of perforating sheet material is characterized in that the material is supported on one side by a matrix having a perforation which corresponds in shape and size to the desired perforation in the material, and in that the material is perforated by a gas-pressure surge which impinges on the other side of the material opposite to the perforation in the matrix. Apparatus for performing the method comprises an insulator 9 having a discharge space 11 and adjustably-mounted electrodes, the material 7 to be perforated being moved at uniform speed over a resiliently-supported matrix 1. The space 11 has a discharge opening 21 adjacent the matrix. In the operation of the apparatus, an electric arc discharge is produced between the electrodes and a cylindrical gaspressure surge results in the space 11 around the discharge zone. The wall 23 of the space 11 acts as a reflector. Gas under pressure, preferably pre-ionized, flows, between discharges, from a container 31 through a duct 29 to the space 11. In a modification, Fig. 2 (not shown), the gas-pressure surge is produced by a slide spark and in a further modification, Fig. 3 (not shown), the initiation of the electric discharge between the electrodes is effected by a thermionic electrode.

A rotary table compression-moulding machine comprises a rotatable drum 1 comprising two plates 2, 3 intermittently rotated between positions I-VIII, and a plurality of moulds mounted on the drum, each comprising a fixed part 7 on the upper plate 2 and a lower part 8 on the lower plate 3. The lower part 8 is mounted on a piston 9 of an hydraulic jack mounted on the lower plate 3 and is raised, in position II, initially at low pressure and then at higher pressure. In position I, the mould is charged with powder from a charging device (Fig. 4, not shown). On being moved to position II by indexing mechanism (Fig. 3, not shown), the intake duct 13 of the hydraulic jack is located over an injector 19 having a hollow piston 21 which is raised so that its nozzle 20 engages the seat 14 of the duct 13. Pressure fluid is applied from duct 29 to chamber 28 to raise the piston 21; valve 25 is then opened by the fluid which passes through duct 13, raises valve 15 and fills chamber 11 of the jack, raising the lower mould part 8. On relief of fluid pressure, valve 15 and piston 21 drop back, maintaining the jack pressure. As the injector 19 is lowered, the table is indexed to position III, where a further, higher compression stage is effected by injector 20. This pressure is maintained, during curing, until the mould is opened when passing from position VII to position VIII. Closure in position II is effected initially at low pressure, discharge valve 40 being in circuit, and then at a higher pressure.
