Title: Improvements in and relating to regulating systems for dynamo-electric-machines
IPC: H02P9/10
Filed: 1926-05-07
Abstract: 252,010. British Thomson-Houston Co., Ltd., (Assignees of Doherty, R. E.).. May 9, 1925, [Convention date]. Systems depending on two or more machines. -The transient variation in the field current of an alternating current dynamo supplying a highvoltage power transmission system occasioned by sudden variations in load is maintained until the automatic regulator has been able to respond to the new conditions. An unsaturated serieswound exciter is included in the exciting circuit of the alternator and arranged to furnish a negative resistance somewhat less than the positive resistance of the circuit, so that the duration of the transient is prolonged for the required time interval. Fig. 1 shows a Tirrill-regulated shuntwound exciter 7 supplying the circuit of the field 6 of the alternator 1. A series-wound auxiliary exciter 8 with unsaturated field system is conrected in the field circuit in such a direction as to function as a negative resistance. The exciter 7 may have an additional source of excitation in its field circuit to avoid instability when the said negative resistance is nearly equal to the positive resistance of the alternator field circuit. The object of the invention is the increase of the ultimate maximum power transmissible by a high voltage long distance power line fed by synchronous machines.

Title: Improvements in or relating to instrument type relays
IPC: G01R1/02
Filed: 1941-09-18
Abstract: 545,757. Electromagnetic relays. SANGAMO WESTON, Ltd. Sept. 18, 1941, No. 11958. Convention date, March 1, 1941, [Class 38 (v)] Instrument-type relays in which a good contact is produced by magnetic attraction between the co-operating contacts, have a layer of non-magnetic but conductive material arranged on one or both contacts to prevent too close an approach of the magnetic parts so that the relay may operate to separate the contacts by the ordinary forces which tend to move the needle 3 when the current varies suitably.

The non-magnetic screw 19 is moreover adjustable to vary the distance to which the magnetic parts can approach.
Patent GB-627978-A (GB)
Title: Earth induction system
IPC: G01C17/36
Filed: 1946-04-18
Abstract: 627,978. Flux valve compasses. BENDIX AVIATION CORPORATION. April 18, 1946, No. 12098. Convention date, April 18, 1945. [Class 37] [Also in Group XXXVIII] In a flux valve compass system the pick-up member is fixed in relation to the craft and its output controls an indicator via adjustable transformers controlled by a gyroscope mounted near the centre of gravity of the craft so as to give a correct reading in spite of pitching and rolling movements. The flux valve compass has four arms 24, 26, 28 and 29, the outputs of all of which are equal. Arms 28 and 29 are both vertical, the other arms being perpendicular to each other and to these two. As the craft pitches the effect of the horizontal component of the earth's field on the fore-and-aft coil 24 is reduced and that of the vertical component increases and at the same time the effect of the vertical component on the vertical coils 28 and 29 is increased and that on the vertical coil reduced. These coils feed the respective primaries of a transformer 62 of which the secondary 76 is normally coupled to the coil connected to the fore-and-aft coil only. The rotor is carried on the axes 58 of the gyroscope so that as the craft pitches the coupling of the secondary with the fore-and-aft coil is increased while its coupling with the vertical coil is reduced. The secondary thus passes on a signal that varies only with the heading of the craft and not the pitch angle. Similarly coil 68 passes on a signal that depends only on heading and not on roll. These signals act on a transformer 90, the secondary of which is driven to the position of zero output by an induction motor 94 which also drives an indicator. Specification 592,394 is referred to.

Title: A new or improved photo-electric line follower
Inventor: HILL WILLIAM FRANK
IPC: B23Q35/128
Filed: 1957-04-15
Abstract: 870,915. Photo-electric line follower apparatus. LANCASHIRE DYNAMO ELECTRONIC PRODUCTS Ltd. July 15, 1958 [April 15, 1957], No. 12240/57. Class 40(3) In line follower apparatus in which a line 16 marked on a sheet or strip 18 is moved across the face of a vertically scanned cathode ray tube, the reduction in light as the scanning spot crosses the line is detected by a photo-multiplier 20 and the resulting signals are phase compared with the time base signal to produce an error voltage which when applied to the tube deflection system causes the mean position of the scan to follow the line. The tube scanning coil 26 is energized from the mains supply 14 via an amplifier 12 and the photo-electric pulses (two produced each scanning cycle) are amplified and applied with a mains supply voltage to a phase sensitive device 23. This device produces a D.C. error voltage across resistance 27 which is in one sense if the photo-electric signals occur in one half cycle of mains supply and in the opposite sense if they occur in the other half cycle. No output is produced if the mean position of the scan coincides with the line. This error voltage is applied via D.C. amplifier 25 to the deflection coil 26. The photo-electric signals are also applied to a phase sensitive rectifier 29 along with a mains voltage which has been phase shifted 90 degrees compared to that applied to the phase sensitive device. The rectifier produces a D.C. voltage which is a maximum when the line coincides with the mean position of the scan and which is progressively less as the line moves to either end of the scan. This voltage is applied as gain control bias to amplifier 12, hence the scanning amplitude is a minimum when the line and mean position of the scan coincide and increases automatically to follow a sudden deviation or to regain control if the line temporarily escapes the sweep of the scan. The output of the D.C. amplifier 25 can be used to control a servomotor which produces a mechanical movement in accordance with the deviations of the line.

Abstract: 310,658. Siemens Bros & Co., Ltd., Long, S. H., and Hodge, M. April 27, 1928. Directive signalling; thermionic heterodyne receivers. - Relates to a multi-valve receiver for direction-finding on continuous wave signals. In order to prevent re-radiation from the aerial of energy from the local heterodyne oscillator, one or more screened-grid amplifiers are interposed between the aerial and the oscillator valve, which may be the usual detector valve or a high-frequency amplifier preceding it. As shown the directional frame 1 is coupled to a non- directional aerial 6 through coils 3, 4 so as to ascertain the " sense" of direction. This is done by closing the switch 26 and adjusting the condenser 5 and tapped coil 4 to resonance. A coil 21 in the plate circuit of the detector valve 18 is back-coupled to a tapped coil 15 in the input circuit so as to generate local oscillations. The preceding valves 8, 13 are screened grid amplifiers, whilst the valve 22 is of the pentode type. When signals are strong the valve 13 can be thrown out of circuit by the switches 11, 14, which may be combined for simultaneous operation.
