Abstract: 1,014,378. Television pick-up tubes. C.S.F.- COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Jan. 21, 1964 [Feb. 4, 1963], No. 2649/64. Heading H1D. In a television pick-up tube, a charge pattern representative of an optical image projected on to photocathode 2 is produced on a dielectric layer 9 of a perforated target, and the opposite conductive side 8 of the target is scanned with a low-velocity electron beam to provide an output signal at a grid 7 which collects the modulated beam passing through the target. The dielectric storage surface 9 is initially stabilized at a uniform negative potential, and subsequent charge patterns, are erased, by applying a short positive pulse to conductive target layer 8 while bombarding surface 9 with slow electrons from a flood gun 5, 6 provided between photocathode 2 and grid 7. A high velocity electron image from photocathode 2 then produces a positive charge pattern on surface 9 by secondary electron emission in a ratio greater than one.

Title: Improvements in or relating to the positioning of work in shoe machines
IPC: A43D21/12
Filed: 1942-03-21
Abstract: 556,831. Lasting shoes. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). March 21, 1942, No. 3763. [Class 17 (i)] The positioning of a partly made shoe on a lart relatively to a machine instrumentality that is to operate on the shoe is facilitated by providing the exposed face of the insole with positioning recesses the locations of which are determined by reference to the contour of the last, corresponding projections located in a predetermined position relatively to the machine instrumentality co-operating with the recesses, To form the recesses, a shoe which has been side-lasted and "pulled-over" at the toe-end is positioned with its toe end against a gauge 36 and the toe end of its insole against a rest 28 and is pushed rearwardly. The guage is pivoted at 38 and swings rearwardly, a pawl 168 engaging a plunger 164 and actuating a switch energising a solenoid 150 which operates a valve admitting compressed air to a cylinder 106, the piston of which descends and depresses a rod 96 which swings a belt-crank lever 94. An arm 92 of this lever actuates arms 74 yieldingly connected to arms on arms 46 swinging gauges 42, 44 connected by straps 64 against the sides of the upper. The gauges are geared together to centralize the shoe under punches 14 backed by pressing equalizing lever 20. Simultaneously with the closing of the gauges a block 222 on the rod 96 actuates a latch 216 releasing a lever 94 to the thrust of a spring 214 which moves a valve 196 admitting compressed air to a cylinder 178 raising the toe-pad 174. When the rest 48 rises so that a pin on its shank reaches the upper end of its slot, the pawl 168 is released, its tail engaging a recess in the shank, the switch being opened, the solenoid de-energized and both cylinders opened to exhaust. The work is thus released. The shoe may then pass to a machine of the kind described in Specification 553,881 but provided with projeetions 244 adapted to engage the recesses in the insole, these projections being formed on a member forming part of the hold-down 232 and co-operating with an abutment 236 for the toe end of the insole adjustable angularly by a screw 240. Specifications 230,433 and 252,252, [both in Class 17 (i)], also are referred to.

Abstract: 347,760. Bottle - washing machines. BLAXTER, A. P. L., Niagara Works, Eagle Wharf Road, Hoxton, London. Feb. 4, 1930, No. 3791. [Class 138 (i).] A conveyer, which, according to the Provisional Specification, is stated to be applicable for bottlerinsing or like machines, is provided with a number of pivoted bottle carriers adapted to be moved laterally at predetermined points in the travel, so as to carry the bottles in and out of the general path of the conveyer, the point of return being different from the point of diversion. A number of bottle supports 1 are mounted on lifting plungers 2 slidably mounted in a rotary disc 3 and adapted to run on a track during the partial rotation. Each bottle support is rotatably arranged with respect to rods 8, which are rotatably mounted in the disc 3 and a spider disposed above the disc. A bottle carrier 21 on an arm 19 fixed to the corresponding rod 8 is arranged above each support 1. In use, the disc 3 is intermittently rotated, during the movement from position A to position B, tappet or cam mechanism beneath the disc 3 turns the rod 8 and consequently swings the bottle carrier out of the circular path and into position B, where the bottle may be removed by an operator and replaced by another. The next movement of the disc carries the bottle to position G, and the following movement brings a cam-surface 35 into contact with a stationary roller 36. The carrier is thus swung back into the path of the conveyer. Make-up pieces may be used to adapt the bottle carriers for bottles of smaller sizes. The circular disc 3 may be replaced by an endless conveyer, the carriers being moved laterally to positions on either or both sides of a straight path.
