Title: Devices for use in electronic reversing means
IPC: H02P27/02
Filed: 1971-04-19
Abstract: 1326497 Control of A.C. motors SIEMENS AG 19 April 1971 [11 April 1970] 26691/71 Heading H2J A protective device for use in reversing means for a three-phase electric motor 9 comprises a sensing device 4 which gives a signal, when there is a load current for rotating the motor in a counter-clockwise direction, say, to actuate a blocking member 7 to prevent application of a load current to reverse the rotation of the motor to a clockwise direction before the counterclockwise driving current has fallen to zero. As shown a three-phase electric motor 9 has its direction reversed by interchanging the phases of terminals U and V by switching triacs A and B, and C and D which are controlled by control circuits comprising pulse generators 3 and 6 respectively, blocking members 2 and 7 respectively and triggering circuits 1 and 8 respectively. Assuming a condition of counterclockwise rotation of the motor phases R and S are connected to terminals U and V via triacs B and A. Transformers 12 and 13 of a device 4 have their primary windings connected in series with the output of triacs A and B. The secondary windings are connected through diodes 17 and 16 and conductor 11 to the blocking member 7 such that, when a current flows in the primary winding transistor 18 is rendered non-conductive and any signals from the triggering circuit 8 are prevented from reaching the pulse generator 6. When the current in the primary windings of transformers 12 and 13 falls to zero transistor 18 becomes conductive and signals from the triggering circuit 8 are transmitted to the pulse generator 6 to switch the triacs C and D and thereby reverse the rotation of the motor to a clockwise direction. A sensing device 5 and blocking member 2 which are similar to device 4 and blocking member 7, are employed in the manner described above when the reversing occurs in the opposite direction, i.e. clockwise to counter-clockwise. A time delay may be introduced to delay the transmission of the switching signal emanating from the triggering circuits 1 and 8.

Abstract: 926,638. Conveyers for electroplating baths. UDYLITE RESEARCH CORPORATION. July 24, 1961 [Aug. 24, 1960], No. 26800/61. Class 78 (1). Articles are advanced in an electroplating plant in barrels carried by carriers 16 which are progressed along monorail 14 from tank to tank by pushers 64a and 64b which carry pivoted pushers 68. Thus pusher bar 64a is reciprocated by fluid cylinder 76 which operates through pivoted lever 84; and pusher bar 64a is connected to sector plate 72 by lever 90 so that the sector bar is reciprocated at the same time and by means of similar pivoted pushers 68 progresses the barrels round the curved path at the end of the tanks. Likewise, the sector plate 72 operates the pusher bar 64b and the second sector bar 72. Elevating mechanism, Fig. 2. Each carrier 16 includes a carriage 26 which moves up and down the carrier. Thus motor 36 drives the gears 30 which coact with racks 34 to give this up and down movement to the carriage, and also drives gear 40 which causes the barrel 28 containing the articles to be rotated. The electric current is passed through the articles by the engagement of contactors 46 with contactor 48. Adjustment device, Fig. 4. A pusher 68 carried by a reciprocating pusher bar 64b may be displaced into the non-operative position by the engagement therewith of bar 94 carried by part 100. The part 100 is caused to rise by sliding in slot 102 when displaced by the fluid cylinder 124. When this is effected, the pusher 68 fails to engage the corresponding carrier which is thus permitted to rest at its station for a double period of time.
