Title: Improvements in or relating to magnetic separators
IPC: B03C1/28
Filed: 1948-07-27
Abstract: 645,393. Magnetic separators. MOLINS, D. W., RUAU, F. F., HARVEY, V. P., NICHOLS, S. A., and MOLINS MACHINE CO., Ltd. July 27, 1948, No. 20036. [Class 72] In a magnetic separator having permanent magnets with a shield of non-magnetic material, the shield is pivotally attached to and covers the magnets during operation and the magnets are pivoted so that they may be removed to a non-operative position and the shield swung on its pivot for the removal of adhering magnetic material. As shown, a row of magnets 1, having a shield 6, is pivotally supported at 3 above a roller conveyer 2 carrying, for example, tobacco. When the shield has to be cleaned of magnetic material the magnet and shield are pivoted into the position shown in chain lines and, at the same time, a hopper 9 is pivoted at 10 into a position below the magnets. The shield is then swung about pivots 8 out of the magnetic field and the magnetic material allowed to fall into the hopper. In a modification, Fig. 3 (not shown), the magnets are moved substantially radially from the roller by a link system and the hopper moved into place below them, a stop on one link arresting movement of the magnets when in the desired position. The trough may be coupled to the magnets for simultaneous movement therewith or the shield and trough may be so couped that movement of the trough removes the shield from the magnets.

Title: Improvements in or relating to control systems for electrically operated elevators
IPC: B66B1/36
Filed: 1937-07-20
Abstract: 493,227. Control of D.C. motors. WESTINGHOUSE ELECTRIC & MANUFACTURING CO. July 20, 1937, No. 20071. Convention date, July 31, 1936. [Class 38 (iii)] Varying E.M.F.- An elevator motor 5 is supplied from a generator 6 the excitation of which is controlled by an ex citer 7 having a field winding 10 energized across resistance ir series with the generator armature, anc the controlling effect of the exciter 7 is increased during a starting or levelling operation by controll ing the resistance tc effect a compounding of the generator greater than that provided for the normal speed correcting regulation of the system. The field 15 of the generator is connected in series with a field 14 of the exciter as one arm of a Wheatstone bridge circuit having its other arms formed by resistances 16, 17, 18. One diagonal of the bridge is connected to a supply in series with resistances 20, 21, while the other diagonal is connected to the exciter 7. In addition to the fields 14 and 10 the exciter has an additional field 22 connected across the motor armature. Upon operation of a car controller 27 a coil 25 is energized to retract levelling switches 24, and a forward or reverse contactor U or D is energized to connect the bridge circuit to the supply in the appropriate direction. The generator field is thus excited and the contactor U or D in closing energizes a brake releasing coil 4 and also the coil FF of a field forcing relay. This relay operates after a time delay to close contacts FF1, and open contacts FF2 so that the series resistance across which the exciter field 10 is connected is adjusted to give normal operation of the exciter. The initial shunt connection of the field 10 is such as to effect over-compounding of the generator and this compounding is reduced to normal when the relay FF operates. By further operation of the switch 27, coils V, VV are energized in turn to cut-out the resistances 20, 21. As the floor is approached at which it is desired to stop, the switch 27 is centred to de-energize the contactor U or D and disconnect the bridge-circuit and apply the brake. The coil 25. is also de-energized to render the levelling switches 24 effective. As the car levels, the contactor U or D is operated by the switches 24 to control the connection and disconnection of the bridge circuit, and the energization and de-energization of the generator field. The brake release coil 4 and the relay FF are also energized by operation of the contactor U or D, the time delay on the relay FF ensuring the over - compounding of the generator during levelling. Specification 480,761 is referred to.

Abstract: 152,822. British Thomson - Houston Co., and Belsey, W. J. Aug. 16, 1919. Driving-arrangements for screw propellers.-Relates to a system of electric ship propulsion. The main turbine 1 is directly coupled to the main alternating-current generator 2 which drives a synchronous motor 5 mounted on the propeller shaft 4. Cooling-water is normally circulated through the condenser 15 by a circulating- pump 5 driven by an alternating- current motor 6 supplied from the main'generator 2. When the main generator is not in use, an auxiliary circulating-pump 8 is employed, driven by a motor 9 which is supplied by an auxiliary generator. A condensate pump 14 may be coupled to the pump 8 or may be separately driven from the same source as tne other auxiliaries. The withdrawal of the circulating-pump from the number of auxiliaries driven by the usual auxiliary turbine-driven direct-current generator reduces the consumption of steam to an amount which is still sufficient for heating the feed-water for the boilers.
