Title: Improvements in and relating to electric motor control
IPC: H02P3/06
Filed: 1919-11-11
Abstract: 158,396. British Thomson - Houston Co., Ltd., (General Electric Co.). Nov. 11, 1919. Systems for continuous current motors only.-Relates to regenerative control of a pair of direct-current series motors operating hoists or the like. According to the invention, the motor armatures A, B, Fig. 2, and their respective series fields FA, FB are connected in parallel in a closed loop for hoisting, while for lowering, the load is allowed to overrun the power and the motors are converted into regenerative braking machines by connecting the armatures in series in one branch and the fields in series in another branch, the fields of one machine and the armature of the other machine being reversed. The required sequence of operations is obtained by providing a master controller having six hoisting steps and six lowering steps, a set of electromagnetic contactors, the contacts of which are numbered 1 to 12 in the diagram, resistance sections r - - r<3> and R<1> - - R<4>, and a reverse-current relay controlling a contactor 13. At the beginning of the hoisting operation, contactors 1, 3, 7, 8 are closed, connecting the motors in parallel as described above. During the subsequent stages of the hoisting operation, the resist. ances R' - - R<4> are successively short-circuited, and then the resistances r<2> - - r<3> are inserted in parallel with the respective fields. When the master controller is thrown to the lowering side, all the contactors open in passing through the " off " position, and then the contactors 2, 4 are closed, thereby reversing the motors and connecting them in series, but with shunt excitation. When the load overhauls the motors, the reversecurrent relay short-circuits the resistance r, allowing effective regenerative braking.

Title: Improvements in and relating to roller guide arrangements for hoists, particularly for haulage skips and cages used in shaft haulage in mines
IPC: B66B7/04
Filed: 1953-10-12
Abstract: 759,621. Guiding arrangements for mine cages and skips; end stop gear. GUTEHOFFNUNGSHUTTE STERKRADE AKT.-GES. Oct. 12, 1953 [Oct. 10, 1952], No. 27957/53. Classes 78 (3) and 78 (5). Guide means for a cage or skip comprises rollers urged into engagement with three sides of a guide rail by relatively weak springs and provided with further stronger springs which absorb any major shocks acting on the rollers. A roller 2 (Figs. 2 and 4) is journalled at 17 in a mounting 6 which is pivoted at 16 to a plate 161 secured to the cage 1. This roller is urged into contact with guide 9 by a spring 11 which is surrounded by a stronger shock-absorbing spring 10. The side plates of mounting 6 may be extended beyond the periphery of roller 2 to form overwind limiting stips which co-operate with thickened end portions of the guides. The rollers 4, 5; 4<SP>1</SP>, 5<SP>1</SP> are yoked together in pairs by mounts 3, 3<SP>1</SP> which are provided with double spring arrangements 7, 7<SP>1</SP>. In a modification (Fig. 7) the roller 4 is mounted on a rotatable eccentric carrier 23 threaded on a non-rotatable shaft 24 which is urged away from a casing 67 by a double spring assembly 70, 71; the arrangement being such that spring 71 exerts a torque on the carrier which thereby urges roller 4 into contact with the guide, whilst large irregularities in the guide produce a large reverse torque on the carrier which is transmitted through the threads on shaft 24 to the shock-absorbing spring 70. In the modification shown in Fig. 5, rollers engaging opposite sides of the guide 9 are slidably mounted on a carrier 41, secured to the cage, and are urged together by a spring 31 which is surrounded by the stronger shock-absorbing spring 30. In all the above arrangements the rollers are each provided with a rubber bush 19 and a steel tyre 20, but in a modification (not shown) they are provided with pneumatic tyres. In another modification (not shown) the springs may comprise a series of rubber plates. In a further modification (also not shown), each roller is replaced by a pair of rollers on a common axle.

Title: Improvements in or relating to x-ray apparatus
IPC: H05G1/40
Filed: 1920-10-04
Abstract: 166,097. Coolidge, W. D. July 9, 1920. [Convention date]. Transformers.- R÷ntgenray apparatus operated by a source of current subject to fluctuations of voltage, is provided with means for controlling the emission of rays from the tube tc secure a predetermined radiographic exposure or effect over a working range of voltage even though the voltage of the source varies. In one arrangement an ordinary time switch is used and the heating current of the incandescent cathode of the tube is automatically varied as the supply voltage changes. In another arrangement the heating current for the cathode is maintained constant and a time switch automatically varies the predetermined time necessary to produce the desired effect with a steady voltage. In the first arrangement, the heating current for the cathode 2, Fig. 1, is obtained from a double transformer 3, wound on separate cores. The core 6, Fig. 4, of the main part 4, 8, provides a highly saturated magnetic circuit while the core 7 of the auxiliary part 5, 9 is open and operates far below saturation. The winding of the auxiliary secondary 9 is such that the E.M.F. in the two parts oppose each other and by properly proportioning the windings the resultant E.M.F. supplying the current to the cathode may be made to increase as the primary current decreases and vice versa, and so that the resultant radiographic effect for an exposure controlled by a time switch 25 is substantially constant over a wording range. In the second alternative method the cathode is heated with a current of substantially constant voltage and a time switch is used by which the time of operation is varied inversely with the square of the primary voltage. The current for heating the cathode may be obtained from a separate source of constant voltage, as from a. battery, or the arrangement above described may be used in which the secondary windines 8, 9 are properly proportioned to give a substantially constant voltage in the filament lighting circuit over a working range as described in Specification 104,404. In the time switch an induction disc 30, Fig. 3, is driven by the electromagnets 32, 33 in the primary circuit 12, 13. A movable plate 43 carrying the contact elements 54, 55 of the switch is adapted to be moved into gear with the pinion 44 on the shaft of the disc 30, by an electromagnet 45 when the control switch 50 is closed. A time pointer 56, mounted on the disc 43, is set to the period of exposure or operation required and a pin 53 on the gear wheel 52 is thereby separated to this extent from the switch 54, 55 which is normally closed and is in the circuit 48, 49 which is connected with the primary circuit. On closing the contact switch 50 the time switch gearing 51, 52, is brought into gear with the pinion 44, and the actual time of operation before the pin 53 opens the switch 54, 55 will depend upon and vary inversely as the square of the voltage in the primary circuit 12, 13 which control the disc 30.
