Title: Improvement in or relating to character identifying apparatus
IPC: G06V10/20
Filed: 1961-12-19
Abstract: 989,494. Automatic character reading. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 19, 1961 [Dec. 19, 1960], No.45549/61. Heading G4R. In character recognition apparatus of the kind in which electrical representations of the character are compared with stored representations to provide signals on different leads for those characters for which the representations are different and on a signal lead for those characters for which the representations are identical or similar there is provided means for producing a signal, unique to each of the characters whose representations are identical, which is compared with store signals to produce a signal distinguishing these characters. The character 201 Fig. 1 is scanned to produce signals which are entered into two shift registers 243, 245. The pattern in one register remains stationary while that in the other is shifted to all possible positions and in each position the member of coincident "black" signal are counted at 257. This count is the autocorrelation function of the character. These functions are compared at 303 Fig. 2 with reference functions stored in registers 299 and the coincident bits summed at 327. The outputs of the accumulators 327 represent the match between the input functions and the associated stored function. The highest match signal is found in the maximum signal indicator 330 and a signal appears on one of the output leads. Since for characters such as "6" and "9" which differ only by orientation through 180 the autocorrelation functions are the same, there is a single lead for both these characters. They are distinguished by counting the number of black signals in the first two or three scans of the character. This is achieved by enabling an And gate 413 at a predetermined time after the first black scan to apply the value then in the counter 257 to comparison circuits 417. In the first cycle of the shift registers the counter compares the patterns both in the same position i.e. it counts the number of black bits in the successive scans. Stored values of expected counts are also applied to the comparators and an output is obtained on the "6" lead or the "9" lead. The trigger 405 is set correspondingly and the "6" gate 401 or the "9" gate 403 is opened to pass the ambiguous signal from the maximum signal indicator 330.

A thermomagnetic device such as an Etting- hausen-Nernst generator or Ettinghausen heat pump comprises a thermomagnetic body with electrodes on two opposite faces and elongate or lamina regions of relatively high electrical conductivity in material of low conductivity extending parallel to the faces and between a pair of opposite sides of the body which in operation form the warm and cold sides. The material of the body should have a narrow forbidden energy gap and high and almost equal mobilities for electrons and holes and the figure of merit is improved by providing anisotropic properties by including strips or needles of highly conductive material in the basic thermomagnetic material. In one example needles measuring 50Á by 1Á of NiSb are placed in a body of InSb so that they lie perpendicular to the applied magnetic field. Alternatively conducting strips of silver, copper or indium may be placed on the surface, or aligned regions of periodic excess doping may be provided. The basic thermomagnetic material can consist of Bi, Bi-Sb alloys with up to 20% Sb (e.g. 95% Bi, 5% Sb), mercury telluride, mercury selenide, Grey tin, magnesiumlead compounds (e.g. Mg 2 Pb), cadmium-arsenic compounds (e.g. Cd 3 As 2 ), monocrystalline graphite and A III B y  or A III B IV C V2  compounds.

Abstract: 472,026. Money-delivering apparatus. DUBOIS, A. Feb. 24, 1937, Nos. 5533 and 5534. Convention dates, Feb. 24, 1936 and Sept. 3, 1936. [Class 27] [Also in Group XIX] In a cash register comprising a magazine for coins or the like of each diameter, each magazine being provided with a coin-discharging device and with counters for registering the number of coins inserted and discharged, the magazines are individually removable from the machine and when removed have their discharge openings closed by automatic means. The machine comprises a series of tubes 6 each adapted to receive coins of a particular denomination or tokens corresponding to bank notes of a particular denomination. The tubes are removably carried in a holder 8 on doors 1 hinged to the casing, the arrangement being such that the upper end of each tube communicates with a coin slot 14 while its lower end co-operates with a coin-delivery plunger 29. Upon the insertion of a coin into a slot 14, a lever 16 is rocked to actuate a counter 15. Subsequent retraction of the coin being prevented by spring member 42, the coin falls into the associated tube. If the tube is full, the insertion of a coin is prevented by the lever 16, an extension 49 of which is blocked by the uppermost coin. The lower end of each tube has a peripheral slot through which the coins may be delivered one at once by the manual depression of the plunger 29, which is fitted with a fullstroke device. As the coin passes through the slot it rocks a plate 23 and actuates a second counter 27. Alternatively, this counter may be actuated by the plunger directly. Delivered coins fall into a bowl 32 common to all the tubes. A graduated slot 43 in the wall of each tube enables the number of coins therein to be read off through a window 51. Compartments 45 are provided for the reception of bank notes and their associated tokens. When the machine is not in use, a glass panel 44 is lowered over the coin slots and a flap 54 is lowered to close the delivery slots in the tubes. Tickets, preprinted as receipts for units of different denominations, may be detached from rolls and issued to the customer, the value of the tickets issued being ascertainable from the number remaining in the machine.

Abstract: 1447196 Line-by-line photocopier LUMOPRINT ZINDLER KG 6 Nov 1974 [23 Nov 1973] 48080/74 Heading G2A In a line-by-line photocopier wherein a plurality of copies is produced by reciprocating an original relative to an exposure slit, copying is effected during both reciprocatory strokes by the use of respective double reflective systems 8 and 9 which are integrally connected and recriprocally movable into and out of operative position, one comprising reflective surfaces mutually inclined at an effective angle of 90 degrees and contacting one another along a line at right angles to the copying line, and the other comprising reflective surfaces mutually inclined at an angle other than effective angle of 90 degrees and contacting one another along a line parallel to the copying line. The first system (shown in the operative position) is for copying during movement of copying line and imaging material in opposite directions, ignoring deflections of the imaging beam other than by the double reflective system. The appropriate system is brought into operative position by magnetic relay drive means 11. The effective angle may be 90 degrees, 45 degrees or 22.5 degrees. The reflective systems may comprise mirrors Figs. 1 and 2 (not shown) or prisms Figs. 3 and 4 (not shown). A plurality of parallel doubly reflecting surfaces may be employed (Figs. 3 and 4). The systems may be situated behind a common objective lens or respective objective lenses. In the former case, the fact that only about half the illumination light is utilized during the same direction copying stroke is compensated for during the opposite stroke by (a) decreasing the illumination intensity, (b) increasing the copying speed, or (c) employing a fixed diaphragm in association with the respective reflective system (Fig. 3). Continuous reciprocation of the original Fig. 9 (not shown) or carriage therefor Fig. 8 (not shown), intermittent reciprocation of the reflective systems, and light compensations during the opposite direction copying stroke is effected with the aid of limit switches. The image may be projected (in mirror image form) on to a photo-conductive drum Figs. 8 and 10 (not shown) or (in right reading form with the aid of a mirror) on to a photo-conductive sheet Fig. 11 (not shown). The exposure slit may be stationary Figs. 8, 9 and 11 (not shown) or moving together with the optical systems; (Fig. 10).
