Title: Improvements in or relating to circuit arrangements employing a plurality of ring counters
IPC: H03K17/74
Filed: 1963-02-11
Abstract: 957,974. Pulse distributing circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. Feb. 11, 1963 [Feb. 14, 1962], No. 5483/63. Heading G4A. Pulses are distributed equally over a number of outputs under the control of a pair of counters fed by a common input and having a common divisor, the arrangement being that at least one of the counters is controlled so as to have a regularly repeating irregularity whereby the distribution of pulses is rendered even. Two ring counters Xl, X2, Fig. 4, have four and six stages respectively so that without irregularity only half of the leads joining the stages would be pulsed. By arranging that when the fourth and sixth stages of X1, X2, respectively are reached that X1 should dwell on stage 4 and similarly that shift should take place from 3(X1), 6(X2) to 1(X1), 1(X2) then the cycle covers all the leads. This irregularity is achieved by a coincidence gate responding to 6(X2) and 4(X1) or 3(X1). Fig. 6 shows such an arrangement in detail, using magnetic core switching circuits.

Abstract: 1494626 Navigational aid B R V Z DE FERRANTI and R M S MURRAY 7 Feb 1975 [7 Feb 1974] 05778/74 Heading G1A and G1F In a navigational aid for indicating a deviation of a vessel from a predetermined fixed compass heading, a bar magnet 44 is suspended from an arm 42 mounted on a conical pivot 43. The arm 42 carries a part spherical encoder surface 45 that is marked with alternating reflective and absorptive stripes. Radiation from a light emitting diode 48 in a reading unit 47 is periodically received by two photo-detectors 49 and 50 when the magnet moves relative to the ship. The photo-detectors are spaced apart in the direction of rotation of the member 45 by an odd number of half stripe widths so as to provide signals phase displaced by 90 degrees. The outputs of the detectors 49 and 50 are fed by way of pulse shaping and level changing amplifiers 27, 28, Fig.3 to a direction discriminator 29 which supplies output signals on lines 30, 31 depending on the direction of movement of the encoder surface. The signals on these lines 30, 31 pass via a combined reset and reversing switch 32 to a reversible counter 33 which will count up or down (from its initial half full count) depending upon the setting of switch 32. The counter's output is fed via a D/A converter to a pair of comparators 35, 38 which are also connected as shown to two potentiometers 36, 39. The comparators actuate an audible alarm 37 or 40 when the signal input from the photo-detectors is greater than the level set by, say, potentiometer 39. A similar embodiment Figs.2a and 2b (not shown) is disclosed wherein the diode and detectors are on either side of an encoder disc with alternating transparent and opaque marks on the edge, the disc being moved by the magnet when the ship's orientation changes.

Title: Improvements in and relating to textile winding machines
Inventor: MACKIE JOHN KAY PRINGLE
IPC: B65H54/52
Filed: 1965-02-10
Abstract: 1,135,382. Yarn tensioning apparatus; winding yarns; pressing arrangements. JAMES MACKIE & SONS. Ltd. 19 Jan., 1966 [10 Feb., 1965], No. 5864/65. Headings DID and D1J. In a yarn-winding machine where the yarn is laid on a rotated spindle by a reciprocated device, in order to prevent the formation of bulges and loose turns at the ends of the package, (a) the tension of the yarn is reduced as the wind proceeds by a control device operated by changing the pressure of a supply of hydraulic fluid, and (b) if desired, the pressure exerted by the winding-head on the package is also reduced by a similarly operated control device. The incoming yarn is tensioned by passing it through a double-disc tensioner, Fig. 3. In this, one of the discs is urged towards the other by a spring, the force exerted by which is gradually decreased as a piston 44 descends in a cylinder, the lower end of which communicates with a source of pressure-fluid by a duct 48. In Fig. 1, a reciprocating guide 12 on a winding-head 14 is mounted on a lever 18 fixed to a shaft 20. As the package grows, the head moves away from the spindle and gradually rocks the shaft so that a cam 80 fixed to the shaft is also rocked to close a pressure reduction valve 52 in the duct 48 through a lever with a camfollower 82. Accordingly the piston gradually falls to reduce the tension on the yarn. The spindle is driven from a motor 6 through an endless V-belt and an expansible pulley 10. The motor is mounted on a pivoted plate 54 linked to a lever 60 also secured to shaft 20. As the latter is rocked with the growth of the package, movement of lever 60 pivots the plate and allows the belt to rise in the expanding pulley to drive the shaft more slowly. To reduce the pressure exerted by the head on the package as the latter grows, the plate 54 is connected to a piston 64 gradually allowed to rise as the amount of pressure fluid admitted to the top of the cylinder through a duct (72) is reduced. This is done by a reduction valve 76 operated by a cam 80 secured to the shaft 20. One throttle may control both ducts 72 and 48. A single cam may operate both throttles.

Abstract: 1426513 Pulse shaping circuits H BOEKELS [trading as DR HANS BOEKELS & CO] 7 Feb 1973 [8 Feb 1972] 5992/73 Heading H3P [Also in Division G1] A filter has associated control means comprising a differentiator followed by a monostable circuit, for by-passing the filter or modifying its response when the rate of charge of signal exceeds a given value so that the output will more quickly follow signal transients. The input signal of the circuit shown has alternate levels respectively representing different loads on a weighing machine and the zero level and has accompanying interference which is removed by a filter 4. The filter delays the response of the output indication and to avoid this the signal is differentiated at 2 and 3 and thresholded so that a sudden change corresponding to a change of load triggers a monostable circuit 7 to cause a switch 5 to temporarily by-pass the filter. A gate 10 samples the signal from the filter in response to a monostable circuit 9 triggered by a delay device 8. The filtering characteristic could alternatively be changed by switching in a different filter.

Title: Improvements in or relating to electric motor drives for printing presses and other machines
IPC: H02P5/46
Filed: 1943-04-15
Abstract: 567,885. Control of two motors. IGRANIC ELECTRIC CO., Ltd. April 15, 1943, No. 6052. Convention date, April 24, 1942. [Class 38 (iii)] A printing press is driven at high speed directly by a large motor LM, and at low speed by a small motor SM through reduction gearing and an electromagnetic clutch energized by a coil C1. Transfer from drive by the motor LM to the motor SM is dependent on the speed of the large motor as determined by a voltage relay V across the rotor circuit, a centrifugal switch or a tachometer. Alternatively, a timedelay may be imposed upon the transfer. Momentary closure of " Reset " button 15 starts warning bell 21 and causes energization of clutch coil C1. Closure of " Inch " button 11 stops the bell and energizes coil Sl of the small motor contactor S, and a mechanical brake on the small motor is released by energization of coil B. Opening of button 11 stops the motor SM, de-energizes the clutch coil C1 and necessitates reclosure of button 15 prior to another start of the press. Closure of " On " button 12 similarly causes closure of contactor S, and additionally energizes a pilot motor 5 to raise the cross-head of a controller 3. As the cross-head rises, coil L1 of large motor contactor L is energized, and coil S1 is deenergized, whereupon coil R1 of rotor contactor R is energized and the clutch coil C1 is deenergized. The controller 3 accelerates the motor LM to full speed if the button 12 is held closed. Closure of " Off " button 13 energizes the pilot motor 5 to lower the cross-head and decelerated the motor LM, re-energize the contactor coil S1 and de-energize the contactor coil R1. When the large motor has slowed down sufficiently, the coil V is energized to cause re-energization of the clutch coil C1. Momentary closure of " Stop " button 14 in any running position of the controller 3 causes opening of both contactors Land S, reversal of the pilot motor 5 and energization of the clutch coil C1 until the controller 3 is returned to its initial position so that the brake is effective to stop the press. Specification 539,203 is referred to.

[Also in Group VIII] A surgical dressing or a sanitary towel comprises an absorbent pad 1 and a cover 2 to the marginal edges 2a, 2b of which heat and/or pressure sensitive adhesive is applied before folding around the pad. The pad may comprise layers and include a moisture-repellent backing. The adhesive coated margins overlap and are caused to adhere to one another when the cover is wrapped around the pad. Covers are made from a continuous length of woven or knitted sheet material which is coated with adhesive along the side edges A and along longitudinal strip-like areas AA, the width of the coating of the areas AA being twice that on the edges A. The spacing between the adhesive coated areas and edges is equal to the desired width of the covers. The sheet is cut longitudinally along lines LL, which divide each strip-like areas into two portions of equal width, and along transverse lines T, to produce covers of the required dimensions. The adhesive coating may be coloured and serves to-prevent fraying of the edges of the covers.

Title: A pilot-valve operated fluid control valve assembly
Inventor: KOBAYASHI HUROTO
IPC: F16K31/40
Filed: 1963-02-15
Abstract: 974,204. Valves. KABUSHIKI KAISHA KEIHIN SEISAKUSHO. Feb. 15, 1963, No. 6130/63. Heading F2V. [Also in Division G3] When a pilot valve controlled main valve 17, Fig. 1, is open as shown, fluid passes directly from an inlet 10c through the main valve seat 26 and around an insert 12 to an outlet 10d; inlet fluid also flows to outlet through the interior of the main valve 17, a bore 27b, the pilot valve seat, and a passage 35; fluid also leaks around the main valve via a stepped bore 16a to the bore 27b whereby the main valve is maintained in a floating condition. To close the main valve 17 a spring-loaded lever, rotatable on a pivot 37, is swung out of engagement with a flange on the pilot valve stem 29 whereupon the pilot valve 38 is seated by a spring 42, the pilot flow is cut-off and the pressure builds up behind the main valve and causes it to close. Resilient rings 23 and 47 engage the seat 26 and the stepped bore 16a when the main valve is closed, the ring 47 being loaded by annular helical spring. The main valve is unseated when the pilot valve 38 is opened by energizing a solenoid 45, the pilot valve being held open by the lever automatically engaging the stem flanges. The function of the spring 42 and solenoid 45 may be reversed; the solenoid switch may be actuated by the lever or the complete valve operation may be controlled by the solenoid alone. The spring 25 in the main valve may be dispensed with and the pilot flow path may additionally incorporate a manual control-valve (Fig. 6, not shown), or a variable restriction. In a modification, an auxiliary valve 81, Fig. 8, seating in the main valve 80 controls flow through the latter, which auxiliary valve is in turn controlled by a solenoid valve 84. In another modification, a filter 90, Fig. 9, is provided in the pilot path, which path both includes a fixed restriction 99 and does not pass through the main valve 92 but enters the latter underneath from a passage 91a in which is disposed the solenoid valve 97; a rheostat may control the energizing current of the solenoid. In a further modification, the pilot opening through the main valve of Fig. 1 is sealed in the closed position of the latter by a spring-loaded conical member in the inlet, which member member also acts as a buffer for the main valve; pilot flow then takes place through a small hole in the side of the main valve. The spring- loaded member may be replaced by a tapered member which increasingly obviates the pilot opening as the main valve approaches its seat so avoiding liquid hammer. In a final modification, liquid flows from the inlet 108, Fig. 13, to a reservoir until the liquid level therein is sufficient to close a float-actuated pilot valve 118 and cause seating of the main valve 112.
