Title: Apparatus for sorting out powders according to particle size
IPC: B07B7/01
Filed: 1949-06-14
Abstract: 659,531. Pneumatic separators. CAMPBELL, J. G. June 14, 1949, No. 15816. [Class 117] In an apparatus for sorting small particles according to size, the particles are fed into an air or gas stream to be suspended therein and projected therewith into an expanding flow collecting chamber 8 comprising a plurality of spaced collectors 9. As shown, the particles are fed from a conical hopper 6 having a cam-operated reciprocating release valve 6d, into a two-part venturi tube 5a, 5b, the divergent portion 5b of which is rotated by a motor 7b and coupled to a beater 7 which breaks up any aggregates. The beater 7 comprises a double conical tube having four radial interior vanes 7a arranged to leave an unobstructed axial bore, and containing balls or large metal particles (not shown) to assist in the breaking up process. The outflow end of the beater is connected, so as to form a second venturi, to a conical or wedge-shaped collecting chamber 8 in which the particles are discharged to fall in a cascade into the spaced collecting funnels 9, the apertures of the funnels 9 increasing in size as the chamber 8 diverges. The outlet of the chamber 8 contains a filter bag 11 to separate the particles still in suspension from the air. The filtered air is then recycled through the apparatus via a pipe 13, having cock and flow meter connections 18, 19, a circulating pump 1, a drying tower 3, and in air flow control tube 4.

Patent GB-158873-A (GB)
Abstract: 158,873. Krupp Akt.-Ges., F. Feb. 12, 1920, [Convention date]. Sparking, preventing. - Inductive circuits are sparklessly interrupted by first switching in parallel therewith a non-inductive resistance which increases the current through an electromagnetic overload circuit-breaker, whereupon the circuit is opened automatically while the resistance is still in parallel with it. In the arrangement shown in Fig. 1, the inductive circuit A when shunted by the resistance C is opened by the circuit-breaker B and isolated by a hand-operated switch E, normally electromagnetically locked. To open the circuit, the two-way switch D<1>, D is moved over to the contacts d<4>, d<1> connecting the resistance C in parallel through the contact d<4> and through the winding b<4> of the cut-out. The current through the winding b<4>, and the increased current through the series winding b<3>, causes the cut-out to open sparklessly, and the increased current through the winding b<4> when the cut-out opens maintains it open. The main circuit is now dead and the hand switch E may be opened, the current in its locking winding e<1> being sufficiently reduced to allow of this. In order to remove permanent magnetism, a reverse current may be sent through the inductive circuit after the main current is cut off. As shown in Fig. 2, this isprovided for by connecting a resistance F greater than the shunting resistance C across a hand switch H on the positive side and a resistance G, switch J and fuse K across the cut-out and half the inductive circuit. After the circuit has been sparklessly opened as described, the switch H is opened and the switch J closed whereby a weak current due to the high resistance F is sent from left to right through the left-hand half of circuit A and a strong current from right to left through the right-hand half. The strong current, which is a reversed current, predominates over the weak current and de-magnetizes the iron in the circuit. In a modification, the switches H, J and D, D<1> are combined in a single push-button switch which ensures the correct switching sequence.

Abstract: 835,223. Protective cut-out arrangements. SIEMENS-SCHUCKERT (GREAT BRITAIN) Ltd., MORTON, J. D., and DIXON, B. J. June 4, 1956 [June 3, 1955], No. 16010/55. Class 38 (5). In an arrangement in which the closing of a contactor 4 under earth fault conditions is prevented by a relay 25 connected in a circuit including a low voltage supply source 65, a star point 89 (or other neutral or " midpoint ") formed on the load side of the contactor, and the fault path, the formation of the star point is prevented when the voltage on the load side of the contactor is above a predetermined value so as to avoid damage should arcing be prolonged at the contactor contacts when opened. In the Figure, the coil 91 of a starting relay 9 is energized on the closing of a starting switch (not shown) associated with a load connected to an outlet socket 1. The resulting closure of contacts 94 of the relay 9 causes the energization of a relay 8 which opens contacts 86 ... 88 to disconnect the star point and closes contacts 84, 85. The contactor coil 41 is now energized over contacts 92 of the relay 9, contacts 84 of the relay 8, contacts 71 of an overload relay 7, a stop button 17 and the contacts 51 of an earth leakage relay 5. In the event of earth leakage, the coil 53 of the relay 5 is energized from the secondary winding 34 of a core-balanced transformer 3 and by opening its contacts 51 causes the opening of the contactor 4 and the disconnection of the auxiliary transformer 6 supplying the relay 9. The relay 9 opens, but as the coil 81 of the relay 8 has been connected to the load side of the contactor through contacts 85 it is not deenergized until arcing ceases at the contactor contacts. If the resistance between earth and any of the phases falls below a predetermined value when the contactor is open and the parts are in the positions shown, then the lock-out relay 25 is energized and by closing contacts 28 connects part of the winding 34 of the corebalance transformer for energization from the transformer 6. As a result relay 5 opens to make it impossible to close the contactor by operating the starting switch. The relay 5 can only be reset by means of a key.
