IPC: H03F3/40
Filed: 1952-07-24
Abstract: 721,626. Valve amplifying circuits. GEN. ERAL ELECTRIC CO., Ltd., and BURWELL, P. J. Oct. 6, 1963 [July 24, 1952], No. 18822/52. Class 40 (6). A circuit for producing a train of impulses whose amplitude is dependent on the value of a unidirectional input voltage comprises a pair of similar valves 1, 2 having a common cathode impedance 3. The input is applied to the grid of the valve 1, the grid of valve 2 being grounded. The anodes are connected over load resistors 5, 8 and a balancing potentiometer 6 to an A.C. supply 9. Two trains of pulses are taken from the anodes and are combined in a further pair of valves 10, 11 having a centre-tapped transformer 12 in their cathode circuits. The secondary of the transformer is tuned to the supply frequency by means of a condenser 16. The circuit may be made to discriminate between input voltages of different polarity by providing a centre tap on the secondary of the transformer and connecting the ends of this winding to two further valves (not shown), each of which has A.C. from the source 9 applied to another electrode, so that anode current flows in only one valve at a time as determined by the sense of the input. According to the Provisional Specification, discrimination may alternatively be obtained by adjusting the potentiometer 6 for unbalance.

Title: Improvements in and relating to electric induction motor windings
IPC: H02K3/28
Filed: 1925-07-25
Abstract: 238,217. British Thomson-Houston Co., Ltd., (Assignees of Macmillan, C.). Aug. 8, 1924, [Convention date]. Void [Published under Sect. 91 of the Act]. Alternating-current motors; windings.-To reduce the effects of higher current and flux harmonies in an induction motor having a doublelayer distributed winding on the primary member, the winding is made of similar coils, the marginal coils in each phase belt being interchanged. In Fig. 1 a two-pole, 3-phase, 36-slot winding with two coil sides in two layers per slot is shown, in which the phases A, B, C indicated respectively by thin, thick, and dotted lines, are connected to a star point 10 and line points 11, 12, 13. The coil pitch is about 61 per cent and is inherently relatively immune from seventh harmonic effects. In a given phase, the coils of one pole are joined to those of the other pole by diametral connectors 16 and the coils within the phase belts are connected by short and longer links 14, 15. The result is that in each layer of the winding instead of the coil sides of a pole following the usual phase sequence AAAAAA, BBBBBB, CCCCCC, they follow the relationship, as is seen, for example, by working counterclockwise from the lefthand element C in slot 17, CAAAAB, ABBBBC, BCCCCA. It is shown in the Specification that the distribution factor, i.e. the ratio of the vector sum to the algebraic sum of the voltages contributed by adjacent conductors in series, is 0.956 : 0.927 for the fundamental frequency and 0.197: 0.056 for the fifth harmonic. Thus, the risk of the motor " crawling " on the fifth harmonic is greatly reduced without substantial reduction of its utilization of the fundamental frequency or its immunity from effects of the seventh harmonic.
