Title: Recognition system
IPC: G06T7/00
Filed: 1974-05-02
Abstract: 1428636 Pattern recognition systems INTERNATIONAL BUSINESS MACHINES CORP 2 May 1974 [29 June 1973 (2)] 19275/74 Heading G4R An arrangement for recognizing the merger of two lines in a pattern, e.g. a printed circuit or a minutia consisting of two merging ridge lines or of a ridge end defined by two merging interridge spaces in a fingerprint, includes a logic matrix comprising an array of cells which are operative to form conductive paths from the centre of the matrix to its periphery, the disposition of the paths corresponding to the' disposition of the lines in the pattern. Outputs from the peripheral cells are used to identify the presence of a merger. The output of a scanner viewing the pattern is digitized and passed to shift register stores which deliver, in true and inverse form, signals representative of the portion of the pattern appearing in a notional 12 x 12 bit window moving over the pattern. The true signals pass to a logic matrix comprising a 12 Î 12 array of cells as indicated in Fig. 2. Each cell is such that it provides an output to its neighbours if it receives an input from a neighbour and from a pattern part. Fig. 2 shows by the black dots those cells which provide an output when a minutia consisting of merging ridges is present in the window. The operated cells form continuous paths from the 4 central cells, connected to voltage source V, to certain peripheral cells. The inverse signals pass to a second logic matrix which performs a similar function, Fig. 3. The outputs from the 44 peripheral cells of the first matrix pass to a circuit (Fig. 6, not shown) which determines whether there are three separate groups of 1-bits and which, if this is so, gives an output indicating the presence of a 3-armed minutia. The output is inhibited if the number of 1-bits in any group exceeds, for example 5 so that a minutia not yet clearly positioned in the window is not recognized and so that excessively wide arms are rejected. The 44 outputs of the second matrix are used in a similar manner to recognize the presence of the split between the ridges. If both a split and a 3-armed minutia are recognized a signal indicating that a minutia is present in the window is generated, and may be used to store the coordinates of the minutia.  In order to prevent recognition of a minutia more than once as it passes through the window the outputs of a symmetrically-placed cruciform array (Fig. 11, not shown) of 28 of the cells of the second matrix, together with a signal indicative of the quadrant in which the split lies, are passed to a circuit (Fig. 10, not shown) which prevents read-out of the co-ordinates except when the minutia is first recognized.

Title: Improvements in apparatus for feeding sprocket-fed cards and the like
Inventor: TURNER FREDERICK JAMES LESLIE
IPC: G06K13/077
Filed: 1966-05-03
Abstract: 1,101,574. Feeding sheets. CREED & CO. Ltd. 3 May, 1966, No. 19419/66. Heading B6B. In apparatus wherein cards are advanced step-by-step past a reading station by stepping means 7 including one or more projections 12 adapted to enter feed holes in a card, each card is inserted in a shoot 17 at a loading station, and is automatically advanced in a series of increments smaller than a feed step, so that the projections 12 can enter the holes in the card without damaging the holes. The shoot 17 (Fig. 1) is moulded, has an opening which is wider than a card, and the card is registered against a side edge (14) by a light spring. The front edge of an inserted card is guided downwardly by fins 4 to depress a roller 1 on a bellcrank 2, whereby a microswitch 3 is operated to start the motor in the reader, and initiate the card feed. The inserted card is held against a friction pad 5 by a spring-loaded roller 9, and the pad 5 is carried on a slidable bracket 6 connected to one end of a feed rake 7. The rake 7 is given a parallelogram locus of motion by a cam 20, but the travel of the bracket 6 is limited to less than a single feed pitch by a stop 11. The rake 7 carries, at the front end, two spring-loaded pins 12, one feed pitch apart, and the main feed pins 13 are spaced some distance from the pins 12. When the card is inserted, the rake 7 is raised and fed to the left, Fig. 2, and subsequently the bracket 6 is moved when a pin 19 on the rake engages the end of a slot in the bracket 6. The card is then moved by the pad 5 towards the pins 12 by less than 0À1 inch. Each cycle is repeated until the pins 12 are engaged in the feed holes in the card, whereupon the card is then fed forward a full pitch each cycle. In a modification (Fig. 3), attachments are provided to enable a tape to be fed by the rake 7, but in this case the tape passes over the top of the shoot 17 direct to the pins 13 on the rake, by-passing the card feed means.

Title: Improvements relating to permanent brake magnets for electricity meters
IPC: G01R11/185
Filed: 1943-11-20
Abstract: 577,382. Supply meters. LANDIS & GYR SOC. ANON. Nov. 20,1943, No. 19443. Convention date, Nov. 30, 1942. [Class 37] A permanent brake magnet has a piece of temperature-sensitive material held against the side of the magnet body by a member arranged under stress in the form of a bridge extending along one or more limbs of the magnet body and resting at or near both ends on the side of the magnet body. A strap b of magnetic material extends laterally of the magnet body a and forms a bridge between the yoke and the pole a <2>. Between the end of the strap b and the pole a<2> is a small block d of thermal alloy the permeability of which decreases with rising temperature. This block is held firmly against one narrow end of the pole a<2> by a tension member in the form of a bracket e which embraces the other narrow end of the pole a<2> and is connected to the strap b by a tension screw f. A pin c passes through holes in the strap b and block d into a recess in the magnet body a. On the yoke of the magnet a the strap b is secured in position by the engagement of a projection g bent out therefrom in a corresponding recess in the magnet. The block d may alternatively be arranged on the yoke of the magnet where the projection g is situated, or there may be a block both on the pole and on the yoke. Straps and thermal blocks may be arranged on both sides of the magnet, a screw connecting the straps so as to stress them and so secure satisfactory bedding of the blocks on the magnet body. The recesses in the magnet body may be produced by swaging during manufacture and may be outwardly flared to facilitate centering of the strap b and block d.

Title: Start and stop device for talking machines
IPC: G11B17/02
Filed: 1920-07-08
Abstract: 147,503. Columbia Graphophone Manufacturing Co., (Assignees of Woods, C. E.). Sept. 9, 1913, [Convention date]. Starting and stopping.-Relates to automatic stopping apparatus for talking and like machines in which a member moved by the motor co-operites with a member moved by the tone-arm in such a way that the motor is stopped when the tone-arm slows down. According to the invention, the apparatus may act by cutting off power from the motor : the motor-switch or like stopping device may be moved positively by the motor itself : the apparatus may be actuated by the disengagement of two normally engaged members, one driven by the tone-arm and the other by the motor; and the machine may be re-started bv returning the tonearm to its starting position. In the form illustrated in the drawings, an arm 27 controlling the motor-switch 5 is traversed across the record by a worm 11 which is driven hy the motor 4 through gearing and engages a tooth 28 pivoted on the arm. So long as the tone-arm is advancing it moves, through link-work, a second arm 23, so that this latter keeps pace with the arm 27, and a knife-edge 24 on the former engages in a hook 31, Fig. 5, integral with the tooth 28 on the latter. When the tone-arm ceases to advance, the hook 31 becomes disengaged and the tooth 28 is left free to turn about the pivot 29, so that the arm 27 can be retracted by the spring 38. A cam 26 carried by the arm 27 thereupon releases the end 35 of a lever 34, the other end 36 of which falls and permits a pawl 14 to drop into engagement with teeth 13 revolving with the worm 11. The switch-rod 17 is thereby drawn forward and operates the switch 5 to stop the motor. The machine is started by first turning back the tone-arm until the knife-edge 24 again engage under the hook 31, and then moving the tone-arm forward to the playing position. The tooth 28 is thereby engaged with the worm 11, and the cam 26 depresses the end 35 of the lever 34 which acts to disengage the pawl 14, permitting the switch 5 to close and start the motor.
