Filed: 1948-10-20
Abstract: 650,242. Electromagnetic relays. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. Oct. 20, 1948, No. 27241. [Class 38(v)] The armature of a relay carries a permanent magnet which forms part of two magnetic circuits which hold it firmly in either of its two positions when the coil of the relay is de-energized. The armature is moved to its other position by sending a current through the coil in the reverse direction. In the form shown in Fig. 1, the armature and magnet 25, which is pivoted at 24 is held in the position shown by a magnetic circuit including a soft iron extension 18 of the yoke 10, the effect of this being greater than that of the alternative circuit through the core 12 and yoke 10. On sending a current through the coil 11 so as to produce a N pole at 29, the armature is attracted to the pole 29 and is there held, even after de-energization of the coil 11, by the now greater effect of this second circuit. In a modification, the permanent magnet is fixed to a soft iron member pivoting about a knife edge and lies between two L-shaped arms of soft iron fixed to the yoke, and linked at their lower ends by a crosspiece.

Title: Electric motor speed control apparatus
Inventor: RUSSELL DEREK BARRY
IPC: H02P7/298
Filed: 1963-07-13
Abstract: 1,108,471. Control of D.C. motors. ENGLISH ELECTRIC CO. Ltd. 12 Oct., 1964 [13 July, 1963], No. 27855/63. Heading H2J. [Also in Division G3] The speed of a D.C. electric crane motor is controlled at first by variation of the firing angle of thyristors 17 in its armature circuit in response to a comparison at 27 between the back e.m.f. and a voltage from control potentiometer 20; when the maximum speed position 44 is reached the field is weakened as the armature current (measured at 40) decreases. When the motor speed is greater than the desired speed the resultant negative error signal operates change-over switches 18, 30 to provide regenerative braking. An electromagnetic brake is held off by the field current through a relay 15. The armature current is limited by a circuit 34 which compares the actual armature current over line 35 with a field strength signal over line 50 and reduces the speed error signal if necessary. Field weakening is effected by a unit 16 which delays the firing time of further thyristors 13 is response to the output voltage of the comparison unit 39. This is illustrated in Fig. 2 (not shown), and comprises four similar bistable transistor circuits with graded threshold levels; initially these are all switched "off" by contacts 42, 43, which establishes full field, but when controller 20 reaches position 44, 42 and 43 change over and, after a delay, a number of the bi-stable circuits are switched " on ", depending upon the difference between the armature current and the reference 41, thus varying the output voltage and the field is weakened by a corresponding amount. Any subsequent increase in armature current does not affect the field, since such bi-stable circuits as are switched " on " remain so until contacts 42, 43 are changed back by movement of controller 20; a reduction in armature current could produce further weakening of the field but this may be prevented by an inhibiting circuit comprising a Zener diode (Fig. 3, not shown). With the speed controller in the off position a switch is closed to establish a weak field at standstill.

Locking member 54 is pivotally mounted on the chassis by screw 49 which forms with slot 47 one of the guides for eject slide member 43. The locking member is formed with a pin 56 which engages slot 57 in the slide member whereby part 58 of the locking member is moved from its full line position 58, Fig. 6, where it prevents movement of the slide member from its upper position when the head plate 21 is in its transducing position 211 to its broken line position 58<SP>1</SP> in which it prevents movement of the head plate to its transducing position when the eject slide member is retained in its lowered actuated position. During the lowering movement of the eject slide member, latch 42 disengages from keeper 44 on the cassette holder 5 so that this and the cassette are moved by springs 38 to their non-operative position and tab 65 on the slide member engages lug 83 on slide 68 to move a feeler member 72, which detects presence or absence of a record tab on the cassette, out of engagement with the cassette. Member 59 is pivoted to the chassis by screw 50 which with slot 48 forms a second guide for eject slide member 43, the member co-operates with tab 65 to retain the slide member in its actuated position. An extension 67 on the member is engaged by a cassette or cassette holder 5 when retained to their operative position to release the slide member and restore the apparatus to its operative position. Slide member 68 for detecting the presence of a recording tab on a cassette is mounted for sliding movement on the chassis and includes a slot 75 which if a record tab is present is moved to a position which allows rod 76, Fig. 6, freedom to move to the right thereby allowing record button 8 to be operated for recording on the cassette tape.
