IPC: G06K9/46
Filed: 1962-11-28
Abstract: 1,060,827. Automatic character reading. ELECTRIC & MUSICAL INDUSTRIES Ltd. Nov. 21, 1963 [Nov; 28, 1962], No. 44914/62. Heading G4R. A decision circuit for a character reader consists of a first integrator to which an input signal is applied, a threshold circuit receiving the output of the integrator and responding if it exceeds a certain value to pass a signal to a second integrator and also, via a feedback loop, back to the first integrator serving to reduce the value of the input. The basic circuit unit comprises a number of input terminals (1, Fig. la, not shown) each connected via a weighing circuit (2) to an adder (3). The output is applied via a threshold device (4) the output of which is applied via subtractor (5), which receives the feedback signal from a following stage. The output of integrator (6) passes via a threshold device (7) to a. quantizer (8) which produces an output of one state if the threshold is exceeded and another if not. The second input to the subtractor (5) is shown as being from adder (9) having feedback inputs (17). The signals on inputs 1 are multiplied by weighing factors, e.g. + 1 or - 1, in units (2) and combined in adder (3). If the resulting signal exceeds the threshold level of circuit (4) the overflow, modified by subtractor (5), is integrated at (6). In another form (Fig. 3, not shown) a group of four photo-cells (A-D) which are scanned over a character are connected to a series of circuits (20, 30, 40 &c.) similar to that described. The signals from cells (A and C) are applied with positive and negative weighing to a unit (20) which gives an output when a horizontal black/ white transition passes between cells (A and C). The same two cells are connected to unit (30) oppositely weighted to obtain a response when a horizontal transition of opposite sense passes between cells (A and C). Similar operations are performed on the outputs of cells (B and D). The outputs of units (20) and (30) are combined in unit (40) to obtain a signal when a horizontal bar is sensed, the signal on the integrator indicating the number of horizontal lines cut in a vertical scan. The output of unit (40) passes the unit (54) which in effect counts the number of vertical scans which contain a horizontal bar and its output indicates a bar of more than a certain length. The outputs of units (30) and (50) are combined in unit (52) to indicate the presence of a diagonal edge. Other combinations are made to obtain signals indicating that other shape elements have been detected.

Abstract: 1,256,232. Finishing fabrics; ironing machine. K. EHEMANN. 27 Sept., 1968 [28 Sept., 1967], No. 46123/68. Headings D1A, D1L and D1S. A continuous steaming and ironing machine for knitted fabric pieces comprises two, opposed endless circulating belts 3, 7 for feeding the pieces to be ironed; a spreading-out roll 4 for uncurling the lateral edges of each fabric piece, the roll 4 being located at the engagement gap 20 of the belts 3, 7 and rotating in a direction opposite to the direction of feeding motion of the fabric pieces; and an end edge-uncurling roll 5 associated with the gap 21 between the roll 4 and the belt 3 and which is displaceable relatively to the roll 4. Each fabric piece is pre-steamed in a zone 1 to increase its flexibility and its leading smooth edge is introduced between the belt 3 and the roll 4 which is provided with opposite saw-tooth threads to uncurl the lateral edges of the piece. The roll 5, which is knurled and is mounted on a carriage 5a which has previously been withdrawn, is advanced as soon as the leading edge is gripped between the belt 3 and the roll 4. A resiliently-mounted plate 6 urges the belt 3 towards the roll 4. The upper belt 7, passing around an edge 8 having a nose-shaped profile, prevents re-curling of the edges of the piece as it passes below a hood 9 into a zone in which it is steamed, smoothed and set by steam passing upwardly from a trough 10 into a thermostatically controlled super heating device 11. Excess steam is sucked out by a fan 12. Each fabric piece passes beneath an electricallyheated thermostatically-controlled roll 13 comprising a covered smoothing roll or a polished roll to impart a lustre to the fabric piece which is subsequently cooled by air sucked through an extractor 15 by a fan 14.

Abstract: 1369643 Spinning yarns EASTMAN KODAK CO 7 Oct 1971 [7 Oct 1970] 46689/71 Heading D1F [Also in Division B5] A hand-held device for joining one moving filamentary tow with another, e.g. in combining the outputs from a plurality of spinning cabinets, comprises a housing 12 adapted for connection to a compressed air source 24 and a pair of slots 26, 28 formed in the housing on either side of a leg portion 16 which extends from the housing. Slot 28 is for entangling the tows to be joined and has at least one orifice 32 connected with the air supply. Slot 26 is a shearing slot and has a manually operable knife assembly 30. In operation, the tow to be joined is passed successively through slots 28 and 26 via the back of leg 16, and the main tow is caused also to travel through slot 28. On depression of valve 86, air is admitted to the slot causing entanglement of the tows and at the same time ball piston 78 actuates the knife to sever the leading end of the tow to be joined thus leaving only a short tail. Spring 72 biasses the knife to the open position. The joining of cellulose acetate, polyester and modacrylic tows is specified.
Patent GB-472052-A (GB)
Abstract: 472,052. Automatic exchange systems. SIEMENS BROS. & CO., Ltd., HUMPHRIES, H. E., and HENSLER, B. A. March 20, 1936, No. 8377. [Class 40 (iv)] In a system in which trunk calls are set up by an operator with the aid of a registersender, a lamp GCL and a buzzing relay GT are controlled from the register-sender to indicate whether the call is being set up over the direct or over an alternative route. The embodiment described forms a part of the system disclosed in Specification 471,764. The operator keys two digits indicative of the trunk group required, and a third digit to initiate hunting or the selection of a particular trunk. As soon as the second digit is registered, relay CS operates in position 3 of the sequence switch DD and the translating switch CM picks up the marking of the register relays, whereupon relays T, CT energize, connecting relays DG, PY, SY to the group control equipment. If the direct .route is available, PY energizes and disconnects SY. As shown, no connection is made to wiper SC1 in this case, but it could be arranged for PY to apply intermittent earth to flash lamp GCL and operate relay GT at intervals. When the third digit is registered, relays AS, SR, S energize to initiate sending. If the direct route is busy but the alternative route is available, SY energizes and applies earth to lamp GCL and relay GT, the latter giving a buzzing signal. If the alternative route when tested is found busy, a revertive signal operates RS (not shown) which connects up PY in a circuit, and an attempt is made to set up the call over the direct route, the corresponding indication being given. Since this route is busy, the call is stored in equipment associated with the group concerned. If delay working is in force in the selected group, DG energizes and applies flickering earth to lamp GCL and relay GT. The operator may press key STK to initiate sending, and the call is stored as before. On calls to be completed over local numerical switches, CS does not operate and sending is initiated by AS in position 6 of DD or by depression of key STK if there are less than four digits in the number.

Abstract: 975,748. Controlling fluid flow. GENERAL PRECISION Inc. Dec. 18, 1962 [Dec. 28, 1961], No. 47806/62. Heading G3H. Flow of a compressible fluid such as air through an orifice 12 is caused to vary between the speed of sound, when a change in the downstream pressure is not reflected in the upstream pressure, and a lower speed, when a relationship exists between the upstream and downstream pressures. The arrangement shown operates as an "AND" gate for digital computation apparatus, the upstream side of the orifice having a supply orifice 10 through which the flow is sonic and an output line 30, and the downstream side being connected to a parallel arrangement of signal input devices each of which consists of a pair of orifices 24, 26 in series through which the flow is subsonic and an intermediate connection 14, 16, 18, 20, 22. The arrangement is such that pulses applied simultaneously to all of the five connections 14 ..... 22 results in subsonic flow through the orifice 12 giving rise to an output signal in the line 30, but pulses applied to any four or less of the connections 14..... 22 do not cause the flow'in the orifice 12 to become subsonic so that no signal is obtained in the line 30. Instead of pressure pulses applied between the orifices 24, 26 control may be effected by reducing the size of the orifices 26, e.g. by plungers. The line 30 may lead to one side of a double-acting bellows, piston &c. the other side of which may be connected to a second circuit identical with that shown, or the time 30 may lead to other pneumatic logical circuits employing fixed orifices or moving elements. An orifice 28 through which the flow is subsonic is coupled downstream of the orifice 12 to function as the equivalent of a summing resistance in an electrical circuit.

Abstract: 1,196,740. Counting-apparatus. DRIVER SOUTHALL Ltd. 25 Oct., 1967 [27 Oct., 1966], No. 48205/66. Heading G4D. [Also in Division G1] In a detector arrangement for counter in which the articles are sensed photo-electrically, the photo-cell gives an analogue output proportional to the sensed area of each article, and an output pulse is produced if this area exceeds a given area. As shown light from a lamp 10 passes through a bi-convex condensing lens and is collimated into a broad uniform beam in a counting zone 14 by a plano-convex lens 12. The beam leaving the counting zone is focused on to a vacuum photo-cell 15 by a plano-convex lens 13. Thus the height of the output pulse from the photo-cell is proportional to the area of the article sensed. This pulse is differentiated by a capacitor to produce two oppositely poled pulses one of which is removed by a diode shunt to ground. The remaining one triggers a Schmitt Trigger to give a standard pulse output which is fed to a counter. A plurality of such arrangements may be located along mutually orthoganal axes such that plane articles are sensed by at least one arrangement.
