Filed: 1970-08-22
Abstract: 1292229 Making electromagnetic relays PLESSEY CO Ltd 22 June 1971 [22 Aug 1970] 40531/70 Heading H1N Magnetic reed contact members are produced from circular section wire 3a, 3b which is cut to lengths which are then secured at one end to an elongated carrier member 6 at intervals along the length thereof to form a comb-like structure permitting further successive operations on the contact members. The wire 3a, 3b is fed from reels 3c, 3d through a straightening and feeding unit 4 to a cropping unit 5 which cuts wire lengths such that the ends thereof overlap a wire 6 which is stepped by a unit 7 after welding units 8, 9 have welded the wire lengths 3e to the wire 6. The steps produced by the unit 7 are related to the spacing between the feed positions of wires 3a, 3b, so that wires from the position of 3b are welded between the wires from position 3a. The continuous comb-like structure 11 is freed between guide rollers at 10, one roller of each pair being toothed and grooved to fit the comb (Fig. 3, not shown) and then the structure is fed past stations 16 to 20 at which swaging, cropping and deburring operations are carried out. A further guide roller unit 10 may be provided after the station 20 before the comb-like structure 11 is cut up by a cropping unit 20 to form comb units for heat treating, cleaning, coating at the contact areas whilst the wire lengths 6 are utilized as carriers controlling and positioning the contacts.

Abstract: 1,209,513. Fishing rods. A. CARABASSE. 26 Aug., 1968 [1 Sept., 1967], No. 40769/68. Heading A1A. [Also in Divisions B4, B5 and F2] A hollow fishing rod or fishing rod section 3 has inside an element of lattice form made from a water-repellent material, e.g. thermosetting plastics, which guides the fishing line through the interior of the rod. The element may be formed from rings 2 joined by threads 1 making a cylindrical cage, Fig. 1, or from threads 5 making diamond-shaped openings, Fig. 2, or from a hollow cylindrical shape with ribs and grooves in the inner surface, Fig. 4. The element may be detachable or non- detachable and attached at the lower end by a castellated ring 4. In one embodiment the rod sections are telescopic. The tip of the rod along which the line is guided externally by guide-rings may be covered with a similar lattice element to prevent the wet line sticking to the tip. In a further embodiment the element may be formed integrally with the rod. The guide element may be made by winding and welding an extrusion covered nylon thread on a mandrel or by blow moulding either inside the rod in which a stretched cotton net may be located or in a two-piece mould. The line may be guided by line guides on the outermost section of the rod which may be attached to the adjacent section by a rigid plastics net, the sections having flats, longitudinal grooves or sharp edges to prevent relative displacement.

Title: Method for controlling stepping motors
IPC: H02P8/26
Filed: 1967-09-12
Abstract: 1,203,295. Control of stepping motors. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 12 Sept., 1967 [15 Sept., 1966], No. 41515/67. Heading H2J. A stepping motor is decelerated with reduced oscillation and stopped in a desired position by interrupting a train of driving pulses before the position is reached, and then applying a clamping pulse when the rotor has moved at least one step beyond the point of interruption and starts to reverse. If the rotor moves beyond the point of interruption by more than 1¢ steps, clamping pulses are applied to the motor equal in number to the number of further steps and at a frequency equal to twice the natural frequency of damped oscillations of the rotor. The motor A is supplied through an electronic switch P controlled by a multivibrator comprising transistors 1, 2, the frequency of the pulses derived from the multivibrator being determined by the time-dependent voltage developed acros the emitter resistance 23 of transistor 24. A control circuit for the transistor 24 comprises switch S which is opened to render transistor 30 non-conductive whereby transistors 31, 38 conduct and diode 37 is blocked so that the multivibrator starts to oscillate. Capacitor 40 begins to charge and transistor 24 is driven to clamp the voltage applied to capacitors 3, 4, this voltage decreasing linearly with time to increase the frequency of the motor-driving pulses. When the switch S is closed, the multivibrator 1, 2 is cut-off and transistor 51 passes the last pulse to a monostable multivibrator OSA which, after a delay period, changes-over a flip-flop FF and drives multivibrator OSB into the astable state. Multivibrator 55, 56 now oscillates freely, with a delay equal to the time constant of the multivibrator OSA, and supplies a first clamping pulse to the switch P which differentiates the pulse for application to the motor. The voltage developed across the resistor 23 is transferred through diode 71 to the circuit OSA whose time constant is reduced as the motor speed increases. The multivibrator 55, 56 is adapted to produce a train of clamping pulses whose repetition rate is adjusted by oscillation of the rotor. When this train is interrupted, the multivibrator OSB drives the flip-flop FF back to its initial state in which it cuts-off the multivibrator 55, 56.
