Patent GB-190812684-A (GB)
Title: Improvements in and relating to Electromagnetic Relays, especially applicable to the Control of Electric Motors.
Filed: 1908-06-12
Granted: 1909-03-04
Abstract: 12,684. British Thomson-Houston Co., [General Electric Co.]. June 12. [Patent of Addition to No. 16,195, A.D. 1906.] Switches; motor control systems.-One of the windings of the relay controlling the circuit of an electro - magnetic retarding-device for the main switch of a motorcontrol system, as described in Specification No. 16,195, A.D. 1906, is connected to the supply circuit through an inductive resistance, and is also provided with a resistance adapted to be inserted or removed by the action of the relay. The fixed core 10 of the relay is provided with a fine winding 7, connected to the source e through an inductive resistance rand to earth through a resistance r<1> or short-circuiting contact 15, magnet windings 26, 27, and the switch b. The movable core 11 is wound with a winding 6 carrying the motor current. The fields produced by the coils 6, 7 oppose one another, that produced by the coil 7 when the resistance r<1> is short-circuited being sufficiently stronger than that produced by the coil when carrying normal values of motor current to cause the relay to rise. The core in rising will lift the disk 15, thereby inserting the resistance r<1> in circuit with the coil 7, and reducing the field produced by the coil but not sufficiently to cause the core 11 to drop. When the motor current in the coil 6 exceeds a predetermined amount, depending upon the value of the variable resistance r', the core 11 will drop, causing the disk 14 to close the circuit of the coil k of the controller locking-device K<1>. The operation of the device is as follows:-When the master switch K is moved to its first position, the motor M is connected in series with the resistance R<1>, R', R<3>, while the winding 7 is connected to the supply through the inductance resistance r. This resistance chokes back the current flowing in the winding 7, thereby preventing it from lifting the core 11 and from opening the circuit of the winding k. In this way, the switch K is prevented from being moved through its first few positions without being subjected to the control of the retarding-device. When the circuit in the winding 7 has risen to its maximum value and the current in the motor coil 6 has dropped to a safe value, the relay core 11 opens the circuit of the coil k and releases the master switch. The switch of last resistance of the controller opens the circuit of the coil 7. The pull exerted by the magnetism produced by the coil 7 on the core 11 may be made constant by adjusting the resistance r<1> to such a value that its insertion and removal from the circuit of the coil 7 counterbalances the gap between the fixed and movable cores. The mechanical construction of the relay is similar to that described in Specification No. 16,195, A.D. 1906.

Pneumatic separating; separating by shaking- apparatus.-Apparatus for separating ore from gangue consists of an inclined jig or bed covered with a mesh up through which an air current is passed, the ore and gangue being crowded in opposite diagonal directions to the sides of the bed by two series of diagonal deflectors secured over the mesh. The jig is suspended by hangers 15, Fig. 1, those at the tail end being adjustable by rods 16, and is actuated by a rod 74 pivoted to a block 72, Fig. 10 adjustable in a recess in one arm of a bell-crank lever 55, a block 60 in a recess in the other arm being engaged by an eccentric 65 on the driving-shaft 64. The block 72 is adjusted by means of a screw 75; and the upper end of the lever 55 is formed into an arm 78 which overlaps the side 80 of the lever, a set-screw 82 passing through the arm 78 and bearing against the side 80 holding the block in the adjusted position. Cushioning- springs 81 are secured to the sides of the jig, and to the standards 5. The mesh 25, Figs. 6 and 7, is secured over a series of supports 22 which have wedge-shaped tops and are set diagonally at a short distance apart. The lower deflectors, which are parallel with the supports 22 and attached along the left side of the jig, are thin for a short distance at 30, then abruptly increased in thickness, forming shoulders 32, and gradually inclining or tapering on their upper surface towards their other ends at the right side of the jig. The deflectors 26, which are attached along the front edge of the jig, are all of the same width as those secured to the left side of the jig, but have no shoulders 32 nor thin parts 30; these deflectors incline from their front to the tail ends, but each to the right is slightly thinner at the beginning than the one adjacent to it on the left side. The upper deflectors 35 are preferably thicker than the lower ones, and are uniform in thickness and width but are set farther apart and extend from the right side to near the left side of the jig. The lower deflectors direct the ore as it is separated from the gangue along the diagonal runways into a longitudinal runway at the side of the jig leading to the shoot 36. The upper deflectors direct the stratum of gangue, after the mass has been stratified, towards the left side of the jig into the shoot 40. The middlings, or part ore and part gangue, are received in the shoot 38; and pivoted gates 47 allow more or less of the separated mass to be directed at will into each shoot. The air, which may be heated, enters through flexible tubes 42 and air holes in the base-board 14, and is spread by plates 45 supported above the holes by supports 44. Reference has been directed by the Comptroller to Specification 17,561/05.
