Title: Improvements relating to electrical control circuits
IPC: G05D11/13
Filed: 1957-11-07
Abstract: 819,445. Control systems. ELECTROFLO METERS CO. Ltd. (Smoot, C. H.). Nov. 7, 1957, No. 34708/57. Class 40 (1). A control system comprises a source of signals, means responsive to the difference between the source voltage and a feedback voltage to produce a controlling voltage, a plurality of devices producing voltages responsive to the controlling voltage, a plurality of rebalancing-voltage sources adjusted by means responsive to their differences from the previously named voltages, and means for adding the rebalancing voltages to form the first-named feedback voltages. The system is applicable to industrial processes (e.g. combustion control) in which a plurality of factors have to be controlled proportionally or successively to meet a demand. In Fig. 1 the slider 10 is set manually or automatically in accordance with the demand, and the amplifier 14 receives the difference between the voltage at the slider 10 and the feedback voltage 15. The slider 17 is thus set in accordance with the difference signal and provides the controlling voltage for the responsive devices 21. Further amplifiers 27 receive the difference between the voltages of the preset sliders 23 and of the rebalancing sliders 25 fed from the supply voltage. The various rebalancing voltages are passed to transformers 28 where they are added to produce the feedback voltage 15. If the demand changes, the slider 10 will be moved and the various motors 16, 26 will run until the sum of the rebalancing voltages again equals the voltage at 10. The proportional contribution of each rebalancing circuit is determined by the preset sliders 23, and these therefore decide the amount of movement of control or indicating devices operated by the motors 26. Each of the factors in the controlled system is therefore varied to the correct extent necessary to meet the new demand. Anti-hunting devices can be incorporated. The circuit of Fig. 2 incorporates two modifications. The rebalancing slider 25 supplies its signal to the amplifier 27 via a potential divider 48, 49 whose mid-point is also connected to the feedback transformer 28 and to a further transformer 51 supplying the next responsive device. The slider 25 therefore reaches the limit of its travel before 17 and 23 do, and the circuit 53, 54, 56, 57 then takes over to complete the rebalancing operation. Thus all of the first factor is used to meet the demand first, and any additional demand is met by the second factor, e.g. reserve fuel. The other modification in Fig. 2 is to control a third factor (e.g. total air supply) in response to the sum of the first and second factors (e.g. a plurality of fuels). The slider 59 provides a voltage representing this sum and the amplifier compares it with the rebalancing signal at 62. Any difference causes the motor 64 to run, thus effecting the desired control and rebalancing the network at 62.

Title: Improvements in and relating to injection moulding machines for plastic materials
IPC: B29C45/53
Filed: 1933-12-11
Abstract: 420,728. Injection moulding of artificial resins &c. BRAUN AKT.-GES., F., Zerbst, Germany. Dec. 11, 1933, No. 34815. Convention date, Dec. 10, 1932. [Class 87 (ii)] In an injection moulding machine for plastic material of the kind provided with a pump the piston of which is adapted to inject the material into the mould, the driving means for the piston comprises an electric motor and transmission mechanism including a spring coupling the motor and the piston, the driving means being adapted to maintain the pressure on the piston when the motor has come to rest owing to increased resistance to the injection motion of the piston. As shown, the material is fed from a hopper 1 to the cylinder 2 of the injection pump and is forced by the piston 3 into a heated cylinder 4<a> communicating through the nozzle 5 with the mould 9. The rod 10 of the piston 3 slides within a threaded sleeve 11 keyed to the casing 12 and engaged by a threaded bush 13. The bush 13 is formed externally as a worm wheel and meshes with a worm on the shaft of the electric motor A. The end 20 of the sleeve 11 is screwed to a casing 21 containing a spring 23 acting between the end 22 of the casing and a flange 19 on a sleeve 18 secured to the outer end of the piston rod 10. The piston 3 is thus actuated from the motor through the intermediary of the spring 23. The motor A may be of the asynchronous type; the armature winding being continually shortcircuited through an adjustable resistance b, Fig. 3, which is connected to the slip rings and acts to limit the starting current and, by its adjustment, to control the maximum torque of the motor when stalled and thus the pressure on the piston. The terminal w of the scator winding is connected directly to the lead W of the three-phase leads U, V, W, whilst the terminals u, v are connected to an automatic change-over relay o, the timing of which is adjustable and which is mechanically actuated by the closure of the mould. The relay o connects the terminals u, v either to the leads U, V, in which case the motor runs in a direction to advance the piston, or inversely to the leads V, U through the intermediary of a switch N. The switch N acts to limit the return stroke of the piston by cutting out the motor and is actuated by a stop 24 on the casing 21.

Title: Improvements in or relating to a method of and apparatus for measuring and/or recording the displacement and/or rate of displacement of a movable member
IPC: G01P3/48
Filed: 1960-10-14
Abstract: 1,007,271. Selective signalling. ALBERT J. BAGGOTT and LONDON ELECTRICITY BOARD. Jan. 4, 1962 [Oct. 14, 1960], No. 35267/60. Heading G4H. In a method of measuring and/or recording the displacement and/or rate of displacement of a body a carrier wave is amplitude modulated at a frequency dependent upon the rate of displacement. In one embodiment a toothed disc is rotated in accordance with the displacement and, as it rotates, it varies the coupling between the primary and secondary coils of a transformer T1. The primary coils form part of a circuit, comprising transistor TR1, which provides a carrier frequency. The signal in the secondary is therefore the carrier modulated according to the variation in coupling. This signal is demodulated by a diode bridge and is passed to a counter to indicate displacement, or to a frequency meter to indicate rate of displacement. To reduce the effect of temperature variation upon the carrier frequency a temperature sonsitive element is placed in the base circuit. If two transformers T1, T2 are provided, displaced about the disc, two signals are obtained which can be used to drive a servo system. A third transformer will permit the direction of rotation of the disc to be determined.

Title: Improvements in or relating to control means for clockwork movements
IPC: G04C11/08
Filed: 1931-12-22
Abstract: 394,965. Electric clocks. SIEMENSSCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. Dec. 22, 1931, No. 35444. Convention date, Dec. 30, 1930. [Class 139.] The oscillating part of a timepiece, for example, the balance or pendulum, is forced to oscillate in time with a part reciprocated by a constant speed motor, for example, a synchronous motor fed from frequency regulated A.C. mains, which may be used to wind up the timepiece in known manner. Various methods of coupling together the oscillating parts are described. In one embodiment a magnet 5, Fig. 1, oscillated by a crank arm 6 and crankpin 7 driven by the motor 8, constrains a balance wheel 2, regulating a movement 1, to oscillate therewith, by magnetic interaction with iron or steel screws 3 carried by the balance 2. Should the motor stop, a spring 10 or gravity control brings the magnet into a definite position. The balance 2 is adjusted when the magnet 5 is stationary so that the movement 1 will give correct time. Alternatively the balance 2 may be adjusted so that the movement 1 would give correct time in the absence of the magnet 5, in which case a magnetic screen, normally held up by a relay or by stray flux from the stator of motor 8, falls under gravity or spring action between the balance and magnet 5 when the latter comes to rest on failure of the supply. In another embodiment the crank pin 7 and arm 6, Fig. 2, oscillate a fork 11, the resilient arms 12 of which impart correction impulses to the pendulum 13 when the latter gets out of step. The distance between the arms 12 is such that when the fork 11 is stationary the pendulum oscillates without contacting with them. In a modification, the fork 11, Fig. 4, may also be pivoted at 17 and is held in the position shown by a magnet 19 in series with the motor 8. Should the supply fail the spring 20 rocks the fork until the arms 12 do not lie in the path of the pendulum. One resilient arm 12 only may be used for correction purposes. In another embodiment a three-armed lever 14, Fig. 3, oscillated by the motor imparts correcting impulses to the anchor 16 of the movement through springs 15. According to another embodiment the oscillating parts may be rigidly coupled, and disconnected when the motor stops, the coupling over being effected electromagnetically by stray flux from the motor field against the action of a spring or gravity control. According to the Specification as open to inspection under Sect. 91, when the oscillating parts are adapted to be rigidly coupled, the movement regulator may be decoupled from the movement and the latter coupled to the part oscillated by the motor during running thereof. When the motor stops this coupling is broken and the movement recoupled with the regulator which is started at the same time in known manner. This subject-matter does not appear in the Specification as accepted.
