Title: High tension separation of materials
IPC: B03C7/00
Filed: 1964-10-20
Abstract: 1, 36, 604. Electrostatic precipitation. CARPCO RESEARCH & ENGINEERING Inc. Oct. 20, 1964 [July 10, 1964], No. 42713/64. Heading B2J. Particles of varying conductivity contained in a mixture of particulate materials are separated by subjecting the mixture while disposed on a grounded conductive surface to a spray of mobile ions produced by a corona discharge pulsed at a rate of about 150 to 800 pulses per second, removing the mixture from the spray of mobile ions, and separately collecting the particles pinned to the grounded conductive surface by the mobile ions and the particles not so pinned. The process is especially directed to the separation comminuted ores containing fine particles ranging in size from 200 mesh down to 5 microns. Mineral particles 38 are fed from a hopper 12 on to an earthed rotor 10 of electrically conductive material and revolving at high speed (e.g. 900- 1500 ft. per min. for a 14-16 inches dia. rotor). The particles are subjected to an ionizing field from an electrode 14 having a corona discharging wire portion 16 directed radially toward the rotor so that the particles become discharged. The conductive particles contact the rotor and have their charges reversed whereas the non-conductive particles do not suffer reversal of charge and become pinned to the surface of the rotor. The conductive particles are then subjected to an external electric field produced by an electrode 20 which may be powered by a different or, as shown, by the same source 18 of unindirectional pulsed voltage (10-100 KV) as the electrode 14. The relatively light conductive particles 40 under the influence of the electric field and also of centrifugal and gravitational forces are removed from the rotor surface and are displaced towards the electrode 20 which may also be provided with an corona discharge wire 22 directed away from the rotor and serving to displace the particles further away from the rotor so that they fall in a compartment 50. As the rotor continues to rotate, the heavier con - ductive particles 44 together with some of the gangue material fall by gravity via compartment 48 to form a middling fraction. The majority of the pinned non-conductive particles 42 are removed from the rotor, surface by a wire electrode 30 connected to a high-frequency A.C. source 32 and fall via compartment 46 as a tailing fraction. Any remaining non-conductive particles still remaining on the rotor are physically removed by a brush 34. The middling fraction may be recirculated to exhaustion to increase the recovery of valuable components of the ore. Dimensional features of the apparatus and experimental results are given.

Title: Improvements in or relating to variable frequency polyphase current generator
IPC: H02P8/18
Filed: 1966-09-29
Abstract: 1,100,280. Control of A.C. motors. OXYMILL S.A. 29 Sept., 1966 [30 Sept., 1965], No. 43659/66. Heading H2J. [Also in Divisions G3 and H3] The field windings 2, 3 of a synchronous motor 4 are supplied at a variable frequency for continuous operation in either direction through a null position, a generator 5 supplying pulse trains to gates 6-9 which are also controlled by generator 10 having a fixed frequency F. The outputs of the gates are connected to amplifiers 11, 13 and 12, 14 associated with the field windings 2 and 3 respectively. The pulse trains from the generator 5 are mutually phaseshifted and have a frequency of F+f, where f is the variable frequency of a control signal applied to terminal A. Each gate has a storage unit and transmits samples of the waveform from the generator 10, the output of the gate being formed by the envelopes of the sample signals, such envelopes being in the form of half sine-waves having a frequency equal to f. Half-waves, which are phase-shifted by one half-cycle, are applied to the winding 2 to reconstitute a full sine-wave at the terminals of the winding, the winding 3 similarly receiving a second full sine-wave which is retarded in phase with regard to the first. The motor is reversed when the frequency of the pulses from the generator 5 is changed to a value less than F. When the control frequency is zero, the motor receives direct-current to hold it in a well-determined position. Each gate comprises switching transistors 15, 16 which transmit the waveform applied to terminal D only during delivery of pulses applied to terminals B, C. Capacitor 19 is charged by each of the successive sample signals, the charge remaining constant between two samples so that the output voltage at terminal S has a step shape which approximates to the waveform to be transmitted. The servomotor may carry out a sequence of movements according to a set programme, the control signal applied to the terminal A being a positional error signal. A magnetic tape 20 records a signal having a frequency which is multiple of F+f, as well as the reference signal having frequency F, whereby the programme can be reproduced by means of reader 21.

Abstract: 923,683. Tip-wagons. GUTEHOFFNUNGSHUTTE STERKRADE A.G. Dec. 23, 1959 [Dec. 23, 1958], No. 43788/59. Class 103(4). A tippable mini car comprises a car box 1, Figs. 2 and 3 pivotally mounted at 3 on a chassis 2, a discharge side wall 4 suspended in pendulum fashion, a roller 8 carried by an arm 7, which may be pivotally mounted on the box so as to adopt the vertical position when the car is not being tipped, which roller is adapted to engage a ramp at the side of the rail track and thus tip the box, and locking means 9, 10 to retain the wall 4 in its closed position until the box has been tipped through a predetermined angle. The wall is also locked in its open position. The locking means comprises a slotted crank arm 9, pivoted at 11 to the box and having a reararm extension 9<SP>1</SP>, and a crank rod 10 pivotally connected in the slot and to the wall 4. In the closed and open positions of the wall 4 the rod has passed through its dead centre position relative to the arm 9. When the roller 8 starts to tip the box 1 Fig. 2, the linkage 9, 10 moves therewith until the extension 91 contacts an unlocking stop 13 on a chassis member 14. Thereafter the arm 9 is rotated clockwise through dead centre and the wall 4 opens under the pressure of the load until the arm reaches a position, again beyond dead centre, against a locking stop 12 on the box as shown in Fig. 3. When the box is empty it commences to return to its normal position under gravity with the wall locked in its open position. The arm 9 Fig. 3, then engages the stop 13, from above, to swing the linkage through about 180 degrees to allow the wall to close and until the extension 9<SP>1</SP> abuts a locking stop 15 on the member 14 and again moves the arm 9 through its dead centre position. The wall 4 need not be lockable by linkage in its open position and in this case a resilient bolt only may ensure that the wall is lockable in its closed position. Instead of a roller 8, the box may have a runway engageable with a roller on the end of a piston rod movable in a cylinder pivoted at a position by the side of the track, as described with reference to Fig. 4 (not shown).
