Title: Ac-dc voltage regulator
IPC: G05F1/575
Filed: 1975-03-18
Abstract: 1492877 Automatic voltage control HUGHES AIRCRAFT CO 18 March 1975 [10 April 1974] 11179/75 Heading G3R An AC-DC voltage regulator circuit includes a series switching element which is turned on during part of each cycle of a periodic voltage produced by a rectifying arrangement by means of a control arrangement responsive to the voltage at the output side of the element. The interval during which the element is conductive is controlled, and the element is disconnected from the output once each cycle to prevent turning on again until the following cycle. As shown in Fig. 2, an AC supply voltage is rectified 18 and controlled by a Darlington transistor pair Q1, Q2 to provide a regulated DC output voltage at terminals 24, 26. The emitter voltage of transistor Q2 is sensed by a voltage divider 60, 62, 64 during each supply half-cycle, and when a preset voltage level is reached, a Zener diode 60 breaks down and turns on a silicon controlled rectifier 30 which diverts base drive current from the transistor Q1, thereby blocking the series transistor Q2, and a diode 56 is back-biased to prevent further conduction. The output voltage is filtered by a capacitor 58. Excessive transient current in the filter circuit passing through a resistor 66 produces current flow through a diode 70 which turns on the SCR 30 to switch off the transistors Q1, Q2. Excessive output voltage breaks down another Zener diode 72 and triggers a crowbar rectifier 78, thereby shorting the output terminals and rupturing fuses 14, 16.

Patent GB-596808-A (GB)
Title: Improvements in fuel supply systems for internal combustion engines, e.g. gas turbines
IPC: F02C7/22
Filed: 1945-05-03
Abstract: 596,808. Fluid-pressure servomotor-control systems. HOBSON (AIRCRAFT & MOTOR) COMPONENTS, Ltd., H. M., and GREENLAND. L. S. May 3, 1945, No. 11309. [Class 135] [Also in Groups XXVI and XXVII] In an internal-combustion engine, e.g. a gas turbine, having a servomotor controlling means for varying the rate of flow of fuel to the engine, and a governor for applying to the control valve of the servomotor, against a substantially constant biassing pressure, a force which varies with engine speed, speed selecting means is provided for adjusting the relationship between engine speed and the force applied to the valve by the governor. As shown in Fig. 1, liquid fuel is delivered by a pump 11 through a conduit 12 to a burner manifold 13, the rate of flow to the burners being determined by a needle valve 18 in a byepass 17. An enginedriven centrifugal impeller 30, constituting the governor, has its inlet connected to the byepass and to one side of a spring-loaded diaphragm 36 by conduits 32, 34, and its outlet connected, through a manually-operable rotary valve 39 for varying the effective radius of the impeller, to the other side of the diaphragm. A control valve 48 connected to the diaphragm, determines the position of the needle valve 18 by controlling the escape of fuel under pressure from one end of the servomotor cylinder 23, said end being supplied with fuel from the conduit 12 through a restriction 25, whilst the other end is subjected to the unrestricted pressure in the conduit 12. Rotation of the valve 39 causes a change in the pressure difference across the diaphragm 36 and consequently a change in the governed speed. The restriction 25 limits the rate at which the valve 18 tends to close should the valve 39 be rotated rapidly to reduce the effective radius of the impeller, i.e. to increase the speed, whilst an adjustable stop 51 associated with the diaphragm limits the opening of the valve 48 to regulate the rate of opening of the valve 18 when the valve 39 is rotated to reduce the speed. A normally open minimum-pressure valve 54, actuated by a diaphragm 55.,subjected on one side to the fuel pressure and on the other side to the combustion chamber pressure controls the servomotor to prevent the fuel pressure from falling below a minimum value under conditions requiring low fuel flow. In a modification, a mechanical governor 130, Fig. 3, which replaces the impeller, acts through a lever 63 upon a spring-loaded control valve 148. Adjustment of the speed is effected by moving the fulcrum 72 of the lever in a slot 73. In a modification of the arrangement shown in Fig. 1, the servomotor controls the output of a variable-displacement pump instead of a byepass valve, whilst in a further modification, also embodying a variable-displacement pump, the valve 39 is replaced by a valve controlling a connection between ,the eye and the tip of the impeller. The servomotor may be of the vane type. Specification 582,084 is referred to,

Abstract: 587,270. Grinding-machines. FOUQUET, E. Sept. 8, 1941, No. 11464. Convention date, Nov. 16, 1939. [Class 60] A grinding-machine comprises a multiple head to which a number of mutually inclined grinders can be fitted, the head being horizontally reciprocated rapidly at right angles to the work which is carried on a table capable of a rapid reciprocation at right angles to the head together with rising and lowering movements ; means are provided for measuring, and compensating for wear of, and for trueing, the grinding discs. The grinding head is mounted on a shaft 26, Fig. 3, driven by a belt and pulley 23 splinod thereto from a motor 1 adjustably mounted for tensioning the belt. The shaft 26 is carried in a tube 46 which can be reciprocated hydraulically by a piston 75 connected therewith and working in a fixed cylinder 76. The shaft has a conical end 35 for the reception of a grinding disc and drives, through a worm gear, a secondary shaft 37 to which a grinder may also be fitted ; the worm gear is enclosed in a casing 45 secured to the tube 46 which can be adjusted about its axis by means of a hand-operated worm 50; a pulley may be mounted on the shaft 37 and drive a smaller grinding wheel mounted on a spindle carried by the casing. Reciprocation of the tube 46 may also be effectect by a handoperated rack and pinion. The work 64 is mounted on a table 123 which is mounted on bearings comprising balls carried in grooves with end return grooves forming a closed cycle, and is hydraulically reciprocated horizontally in a similar manner to the tube 46 ; alternatively the table may be reciprocated by a hand or electrically-operated screw 153. The table is raised and lowered by a fixed screw 216 engaged by a nut operated through changespeed gearing arranged on shafts 187, 200, from an electric motor 180. The table may be manually raised by a hand wheel 218 and gearing 220, 221. To indicate wear on the grinding wheel, a feeler 230, Fig. 6, is provided which rests at the same level as the lowest part of the wheel and is formed in one with a toothed sector 233 in mesh with a gear 235 which drives a vertical rack 236 driving, by means of a small rack 238, a pinion 239 operating an indicator. A feeler 256 rests on a bar 257 partaking of the movement of the work table and drives a rack 259 carrying a gear 260 which rolls on the rack 236 ; the rotations of the gear 260 thus depend on the displacement of the feeler 256 which measures the depth of cut corrected by the displacement of the feeler 230 measuirng the wear of the grinder. Setting mechanism is provided whereby when the selected depth is cut a contact is closed and the upward motion of the table reversed. The grinders are dressed by a wheel 300 adjustable by a hand-operated worm 305, the setting of which can be observed against a scale. A periscope enables the grinding operation to be observed.
