Title: Incremental bidirectional drive mechanism
IPC: F16D7/02
Filed: 1960-04-21
Abstract: 913,084. Reverse gear; escapement mechanisms. TALLY REGISTER CORPORATION. April 21, 1960 [May 18, 1959], No. 14047/60. Classes 80 (2) and 80 (4). Mechanism for converting the continuous unidirectional rotation of an input shaft 57 into intermittent rotation of an output shaft 11 in either direction comprises escapement wheels 19, 20 which are frictionally coupled to gears 45, 28 which are driven in opposite directions through gear clusters 51, 52, 54 and 55, loosely mounted on a shaft 53, from a bevel gear 56 on the input shaft 57. Each escapement wheel comprises a grooved hub 23 on which friction discs 27, 29, spring washers 26, 30 and gear-wheel 28 or 45 are mounted. Bevel gears 21, 22 are formed integrally with the escapement wheels 19, 20 and mesh with a spider bevel gear 15 on the output shaft 11. In the neutral position of an operating switch 66, the escapement wheels 19, 20 are prevented from rotating by pallet levers 46, 36, the wheels then slipping with respect to gear-wheels 28, 45, respectively. The switch 66 may be moved to one position in which it connects an electromagnet 48 with a pulse generator 65 whereby the pallet lever 46 is disengaged from the escapement wheel 19 which, through the gears 22, 15, effects drive of the output shaft 11 in one direction. Alternatively, the switch 66 may be moved to another position in which it connects an electromagnet 41 with the pulse generator 65 whereby the pallet lever 36 is disengaged from the escapement wheel 20 which, through the gears 21, 15 effects drive of the output shaft 11 in the reverse direction. Either gear cluster 51 or gear cluster 52 may be secured to shaft 53 by a set-screw 62 or 63 so that power may be taken from or supplied to shaft 53 through a pulley 61.

Filed: 1974-03-29
Abstract: 1465602 No-break standby systems SOC ANON DES ETABS ADRIEN DE BACKER 29 March 1974 14105/74 Heading H2H An auxiliary power supply unit comprises a transformer by means of which a load can be supplied from an A.C. source where this exists and from a battery by way of a converter when the A.C. supply fails, the battery being charged from the A.C. source when this source is supplying the load. A load 30 is normally supplied from an A.C. source R by way of transformers 40 and 1, 2, an inductive impedance 41 being inserted in the connections between the transformers. Upon failure of the A.C. supply R, the supply to the load 30 is maintained by a battery 20 via a converter which includes thyristors 3, 4 and diodes 5, 6. The system includes a comparator 42 to which are fed the battery voltage on line 43 and a constant reference voltage, signified by a Zener diode 45 on line 44, the output of the comparator being used to control a synchronizer 9. The outputs of the synchronizer 9 control the firing points of the thyristors 3, 4, such that the converter functions as a rectifier for charging the battery 20 when the A.C. supply R exists and as an inverter for supplying the load 30 from the battery 20 when the A.C. supply R fails. In a second embodiment the converter comprises four thyristors and four diodes in a bridge formation. In a further arrangement the transformers 40 and 1, 2 may be arranged on a common magnetic core comprising a magnetic shunt.

Abstract: 595,166. Phase-changing. FOSTER TRANSFORMERS & SWITCHGEAR, Ltd., and COURTNEY, T. June 6, 1945, No. 14219. [Class 38 (ii)] A transformer for changing from twoto three-phase operation has three limbs, A, B, C, on each of which are one winding 5, 6, 7 for the three-phase circuit shown star connected at n, and two windings 8, 9; 10, 11 ; 12, 13 for the two-phase circuit, of which each phase has three windings, one on each limb, connected in series ; the respective relative turn ratios in the two phases are .471, .173, .644 and .471, .644, .173. Since the number of turns in the twophase windings on one limb may be equal, and of the same phase, a common winding instead of 8, 9 may be used, Fig. 2 (not shown). An auto-transformer arrangement is also described, Fig. 3, in which the three-phase windings 15, 16, 17, star connected at n are suitably tapped and the two-phase circuits are formed by parts of the three-phase windings 16, 17 in series respectively with a further winding 12 or 10 and a common part of the three-phase winding 15. The tapping on winding 15 forms the two-phase neutral point n<1>. In another auto-transformer connection, Fig. 4 (not shown), the two-phase circuits utilize more turns of the main windings than the three-phase circuit which is connected to the winding taps.
