Title: Improvements in or relating to apparatus for use in the automatic recognition of printed characters
IPC: G06V30/10
Filed: 1966-06-17
Abstract: 1,132,486. Character recognition. SIEMENS A.G. 17 June, 1966 [18 June, 1965], No. 27159/66. Heading G4R. A character is scanned in columns (or rows), detection of a character form element causing storage of a form element characterizing signal in a store section corresponding to the current character column section, equality between character column sections in adjacent columns causing transfer of any characterizing signal stored in the store section corresponding to the first to that corresponding to the second. In Fig. 3, the scanning signal elements (1 for character, 0 for background) are applied at n, and via a one-column-delay shift register to n-1. Each 1-to-0 transition at n is detected by DO to step a distributer SV, each step causing read-in to a corresponding column of core (or trigger) matrix MS from intermediate stores SED to SEk. Each 1-to-0 transition at n-1 is detected by OD to step a sampler LV, each step causing read-out of the corresponding column of the matrix MS to intermediate stores SAD to SAk. Whenever the inputs n and n-1 both become equal to 1, a gate G11 produces a 1 output, any 0-to-1 transition at the gate output being detected at D11 to set the matrix-input intermediate stores SEd1 to SEk in accordance with the settings of corresponding output intermediate stores SAD to SAk, except that the OR of SAD and SAD1 is used to control SEd1 Stores SED and SEd2 are also set on detection of a divergence form element d2. (The divergence is detected by the sequence ... 111 . . . in one scanning column followed by ... 101 . . . in the corresponding position of the next.) As shown, each of the column selection wires from distributer SV selects the same numbered core in each row except in the first row AD to ND where it selects the preceding core. This ensures that the two stored bits representing a divergence, one bit for each limb of the divergence, are stored in the same column of the matrix. Other matrix rows may be used for other form elements, e.g. vertical, horizontal and diagonal straight lines, semicircles, and convergences. Coded groups of bits may replace the single bits stored in cores above. Means Sd1 and GVUF detect an enclosed space in response to detection of the two limbs of a divergence D1, D2 and a convergence k. Fig. 4 (not shown) shows circuitry for storing a 1 bit in an extra matrix row (Ae to Ne) to indicate that a character section has ended. Such a 1 bit, when read out, if accompanied by a 1 bit in at least one of other matrix rows, will enable an AND gate (UGr) permitting the part of the last column crossing that section to be retained by recirculation in the one-columndelay shift register. The section-end bit is stored under control of circuitry responsive to the control input to the AND gate (UGr) and to the inputs to and the penultimate stages of the one-column-delay shift register and of another such register preceding it.

Abstract: 521,544. Weighing-apparatus. POWELL, G. F. W., and MOLINS MACHINE CO., Ltd. Sept. 21, 1938, No. 27533. [Class 143] Vibration, preventing.-In weighing mechanism having a pivoted weigh beam, vibration is damped by the action of a magnetic field upon a conductor loop (e.g., the weigh beam itself) intersected by the axis disposed about the fulcrum of the oscillation of the beam so as to make a turning movement in the field in response to movement of the beam, the field being produced by two opposite poles at opposite parts of the conductor loop remote from the fulcrum. As shown in Fig. 1, the weigh beam 1 consists of a rectangular frame of aluminium or other non- magnetic material mounted on a knife-edge fulcrum 2. The pole pieces 10, 12 of an electromagnet 8 enclose the cross members 21 of the rectangular weigh beam. The cross members are curved concentrically with the fulcrum 2 to reduce the air gap. The movement of the weigh beam produces a current round the loop or rectangle of the beam and quickly brings it to rest. In a modification, Fig. 3, permanent magnets 14 are employed, each with pole pieces 15, the poles being arranged so that the induced currents are in the same direction round the loop. Means are provided to adjust the strength of the magnetic field. Specifications 431,478, 442,566, 521,585, and 489,058, [Group XXXV], are referred to.

Abstract: 263,588. Holt, H. E. S. Nov. 7, 1925. Periodic brakes; blocks acting on drunrs.-In apparatus for lowering mail bags &c. from aircraft wherein the larger of two parachutes only becomes operative when a pilot weight touches the ground, as described in Specification 168,924, the unwinding of the pilot weight cable from its drum effects a gradual application of brakes to the drum through worm reduction gear and screw and nut mechanism when the necessary length of cable has been paid out. The cable e<1> for the pilot weight is wound on a drum which is initially prevented from rotating by a safety pin g which must be withdrawn before use, and by a pin g<1> which is withdrawn by a static cord g<2> attached to the aircraft. As the weight falls a worm on the drum spindle turns a worm wheel forming a nut on a threaded spindle h which moves axially until the enlarged threaded portion engages a block h<4> to apply brake blocks h<1> to the drum when the necessary length of cable has been paid out. The spindle h has a keyway engaged by a, pivoted key which can be moved out of engagement with the keyway to enable the spindle to be turned to set the apparatus.

Title: Improvements in or relating to means for damping the mechanical oscillations of overhead electrical lines
IPC: H02G7/14
Filed: 1930-09-19
Abstract: 367,767. Damping vibrations of overhead cables. SIEMENS-SCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. Sept. 19, 1930, No. 28069. Convention date, June 7. [Class 36.] In order that vibration dampers suspended from an overhead line may exert their influence over a wide frequency range, the internal friction oi the dampers is so chosen that the ratio <alpha>/# # lies between 0À1 and 10, where alpha represents the damping exponent of the dampers and f the mean frequency of the line oscillations. The damping exponent alpha may be determined from a formula connecting the logarithmic decrement and the natural frequency of vibration of the dampers. The dampers may consist of dashpots provided with adjustable valves for controlling the friction between the moving parts, or may be formed by a bundle of weighted leaf springs secured together by adjustable clamps. The internal friction of the damper shown in Fig. 2, comprising a ring 4 supported by springs 3 from a collar 2 attached to the line 1, may be increased by braking devices such as tubes on the collar 2 rubbing on studs carried by the ring 4, or by discs secured to the ends of the collar 2 which frictionally engage the ring 4.
