Abstract: 696,413. Automatic control systems for aircraft. BENDIX AVIATION CORPORATION. Jan. 28, 1949 [May 19, 1948], No. 2447/49. Class 38 (iv). In an aircraft automatic pilot a source of com. pass signal voltage is manually adjustable to set the course and supplies a relay system operating the control surface servomotor; follow-up and thermal time delay anti-hunting circuits are provided. As shown, the control surface is driven by the continuously rotating motor 66 through the differential gear 65, the direction of rotation of which is determined by which of relays 69, 70 is operated by the control signal voltage developed at potentiometer 20. The output of the source of compass signal voltage 11 is set manually, at potentiometer 20, to adjust the course, and is applied to the control grids of the A.C. energized valve 36. The latter supplies the relays 46, 48, one or other of which is operated in accordance with the sense of either the craft deviation or the set course, and which closes the corresponding brake 69 or 70, thereby determining the direction of rotation of the output shaft of differential gear 66 driving the control surface. A follow-up signal is provided by the potentiometer 75 mounted on the differential shaft. An integrating or time delay signal is derived from circuit 100 in which the grids of valve 104 are fed from the control signal voltage and the anodes supply the heating elements of the time delay device 110 which forms part of a normally balanced bridge, the output of which is applied in series with the output of 20.

Title: Improvements in and relating to alternating voltage regulators
IPC: H02P9/32
Filed: 1952-01-30
Abstract: 729,131. Automatic voltage control systems. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 30, 1952 [Feb. 8, 1951], No. 2507/52. Class 38 (4). [Also in Group XXXIX] In an automatic voltage control system for an alternator in which the field excitation is derived from the alternator output via a rectifier in series with a controlled magnetic amplifier, the amplifier is controlled by unidirectional pulses, the duration of which depends on the alternator output voltage. These pulses are obtained by rectifying, at 43, the output of a transformer 37 having a split, easily saturable core, and a short-circuited winding 42. A condenser 47 partly filters the output voltage pulses and controls the degree of accuracy of the regulator. The pulses are applied to a control winding 36 on a saturable reactor 15 and are, in this embodiment, of such a polarity as to produce a flux opposing that due to the windings 18, 19. These latter are energized from the alternator output and their control output is rectified at 21 and used to control a further reactor 25 which energizes the field of the alternator. It is shown that as the voltage of the alternator rises, so the trailing edge of the pulse from transformer 37 is advanced in phase, and this advance causes the output of the reactor 15 to increase. This increase in turn, decreases the output of reactor 25 and so corrects the alternator excitation. In a modification, Fig. 7 (not shown), the input to transformer 37 is retarded in phase by 90 degrees by a phase-shiaft network, and the pulse output is applied to winding 36 in such a direction as to assist the windings 18, 19. Then, it is shown that an increase in alternator voltage causes a decrease in the output of the reactor, and this decrease is used, without phasereversal, to control the excitation of the alternator. The winding 51 on reactor 15, Fig. 1, is also energized with voltage pulses derived from the alternator output via rectifier 52 and phase advancing network 53, 54. These pulses aid the windings 18, 19 and since the alternator's output waveform is distorted on load in such a manner as to advance the phase of the wave, this advance, acting oppositely to the advance of the pulse applied to winding 36, tends to increase the alternator excitation as the load increases.

Abstract: 233,039. Ross, A. Jan. 31, 1924, Water-circulating, apparatus for promoting; sediment-collectors and settling-chambers.-For ensuring the constant pressure of liquid against the water side of any part of the generator exposed to radiation and flame or hot gases, circulation of the water is maintained by means of a pump and a cone K situated in the upper part of the water space of the boiler communicates by way of a suction pipe SK with a circulator C having a depending diaphragm T. Sludge entrained in the water entering the circulator is deposited at the bottom and is blown off occasionally through the sludge pipe SP whilst oil runs to the surface and is blown off through the oil-circulator pipe OP. The water passed by the circulator is drawn by a pump RP driven by a motor M through a filter F and is delivered to a drum D arranged in the centre of the water drum WD. A series of nozzles N extend from the periphery of the drum into proximity with covers OK which cover the ends of the water tubes P. A vigorous and positive. circulation of water is thus promoted. In a modification, the delivery pipe DP, Fig. 5, terminates in a tube U which is inclined towards the water-tubes P which are shielded from the down-comer tubes R by a diaphragm L. In another form, the stream of water from the pump is directed along the rear plate of a combustion chamber. When the boiler is standing- by or being lighted-up, the circulation through the pump is shut off and the flow of water is then effected through a bye pass BP controlled by a valve.
