Title: Improvements relating to electrical measuring, indicating or relay apparatus for polyphase circuits
IPC: G01R29/16
Filed: 1921-02-14
Abstract: 159,148. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Fortescue, C. le G., Chubb, L. W., and Slepian, J.). Feb. 13, 1920, [Convention date]. Induction-motor relays.-Apparatus for measuring, indicating, or being operated by either or both of the two balanced polyphase components into which an unbalanced polyphase system of currents or voltages may be resolved, comprises a synchronously running machine with one winding connected directly or indirectly to the system so as to produce a magnetic field having two balanced components, one of which is stationary with respect to the other winding of the machine and the other of which rotates at a double-frequency speed with respect to this other winding, one or more measuring, indicating or relay instruments being connected to one of the windings of the machine. In the form shown, the stator 7 of an induction motor 8 is connected in star to the mains 2, 3, 4 carrying a three-phase unbalanced load. The rotor 9 of the motor 8 is driven in the direction opposite to that in which it would normally rotate by a synchronous motor 10, the rotor windings 9 being connected to a voltmeter 11 of the induction-motor type, which may have relay contacts 12. One component of the field produced by the stator 7 rotates at the same speed and in the same direction as the rotor 9, and therefore does not cut the rotor windings. The other component cuts the rotor windings with double the frequency of supply and induces a voltage which is measured by the voltmeter 11. The other component may be measured by reversing the connections of the stator winding 7 to the mains 3, 4, or by reversing the motor 10. The motor 8 may have a squirrel-cage rotor, in which case the stator windings 7 are connected between the mains 2, 3, 4 and the voltmeter 11. Two induction motors may be employed having squirrelcage rotors driven synchronously by the motor 10, the stator windings of the two induction motor; being connected in series to the system so that one offers high impedance to one component of the voltage system and the other offers high impedance to the other voltage component rotating in the opposite direction. Two voltmeters or relays are connected one with the windings of each machine; for instance, the separate components of the pressure may be separately measured by voltmeters connected across one phase of each stator winding, balancing-reactances being connected across the other phases. The separate components of the currents may be measured by similar means, the stator windings being connected to the secondaries of current transformers, which secondaries may be shunted by resistances. Various factors, such as the components of the power, may thus be found.

Abstract: 741,177. Winding webs. STURGEON, J. Feb. 22, 1954 [Feb. 25, 1953], No. 5291/53. Class 100(1). [Also in Group XX] Apparatus for winding or rewinding a flexible strip comprises a bench or box-like structure, members on which the film is wound or unwound carried by rotatable shafts, a driven member on each of said shafts, a swinging and slidable cradle on which a motor is mounted, transmission means carried by the cradle and driven from the motor for imparting motion to one or other of the members in turn, means comprising a member so mounted on the structure and working through a gate change and so connected to the cradle as to control the positions of the latter and the transmission so as to obtain forward and reverse drives of the members and also a neutral position in which neither member is driven. One form is shown in elevation in Fig. 1 and in transverse section in Fig. 3. Plates 17, 18 for carrying film spools or coils are driven from discs 13, 14. A cradle 3 supported on a rod 5 carries the driving motor 2 having on its spindle a rubber-tyred wheel 8 driving a disc 9 on a shaft 10, also carried in the cradle and having rubber-tyred wheels 11 and 12 at its ends. The latter wheels engage alternatively with the discs 13 and 14 respectively as the cradle 3 is slid along the rod 5 by operating a lever 28. The lever is carried in a universal mounting at 22 and is slotted to embrace a rod 26 projecting from the cradle 3. It also carries pins 25 engaging the rod. A gate in the plate 1 ensures that the lever 28 is first moved to the dotted position in Fig. 3, rotating the cradle 3 about the shaft 5 to disengage the operative one of the friction wheels 11, 12. It may then be moved to slide the cradle and then engage the other friction wheel. The weight of the cradle provides the frictional force but may be assisted by a spring 30. When the film is wound without a spool it may be controlled by rods 33 pivotally mounted to one side of the plates to be movable to a position radially across them. The film passes from one coil or spool to the other over an illuminated panel in the plate 1.
