Patent GB-677097-A (GB)
Title: Improvements in control gear for steam turbines
Inventor: COWLIN FREDERICK JOHN
IPC: F01D17/26
Filed: 1950-02-10
Abstract: 677,097. Fluid-pressure servomotor-control systems. ENGLISH ELECTRIC CO., Ltd. Jan. 19, 1951 [Feb. 10, 1950], No. 3462/50. Class 135. In a speed control for a steam turbine, the movements of the speed governor sleeve are transmitted mechanically to a piston valve working in a movable, ported, follow-up sleeve to control the leakoff from a chamber which is connected with the ported sleeve and is supplied with pressure liquid, the chamber also communicating hydraulically with a power device actuating the main steam valves of the turbine, and the ported sleeve, which moves through the chamber wall, is provided with a flange connected to the chamber by a bellows so that the control pressure in the chamber can act on the flange in opposition to a resilient restoring force. The centrifugal governor 1 acts through a bell crank 3 and an adjustable link 6 on a lever 5 pivoted on a normally-fixed fulcrum 36, and the lever moves a piston valve 15 to vary the area of escape ports 16 for pressure fluid supplied to a cylinder 17 from a line 50, past a restriction 20. The ports 16 are provided in a movable sleeve 19 which has a bellows seal 29 with the cylinder and which is pressed upwards by an adjustable spring 18 ; and the modulated pressure produced in the cylinder by movement of valve 15 acts on a piston flange 39 on the sleeve 19 to neutralise the movement of the valve and so provide a follow-up pressure in the cylinder. This pressure is communicated to pistons 23, 123 which, through floating levers 24, 124, actuate valves 30, 130 controlling servomotors 25, 125 connected to the inlet valves 28, 128 of the turbines. The movements of the servomotor pistons are fed back to the valves 30, 130 through the floating levers 24, 124 so as to provide a further follow-up. The fulcrum 36 of lever 5 is carried on a piston 69 which is normally pressed upwards, against its spring loading, by an oil pressure produced by a control apparatus subject to the vacuum in a turbine. Should the vacuum fail, this oil pressure will fall and piston 69 will move lever 5 to a position such that the inlet valves of the turbines are shut down. There is a screw-and-nut connection between lever 5 and the stem of valve 15 so that the position of the valve can be adjusted to set the control speed of the governor by means of a hand-wheel 13 or a remotely-controlled motor 11.

Title: An improved means of disconnecting undesired electric coils or circuits
IPC: H01H19/58
Filed: 1923-02-06
Abstract: 214,751. McCarry, P. A. Feb. 6, 1923. Regulating-switches; contacts.-Relates to a contact stud provided with means whereby a circuit, or part of a circuit, can be completely disconnected, and, in a particular application to wireless turning coils, whereby the number of coils or parts of a coil in circuit can be so varied that the undesired coils &c. can be completely disconnected and dead end effects eliminated. The contact stud, as shown in Figs. 2 and 3, comprises an insulating sleeve 1 within which slides a contact rod 4, provided with a head 5 and nuts 7, 8 for clamping a lead 9. A spring 12 normally holds the nut 8 in engagement with nuts 10, 11 screwed on the sleeve 1 and securing another lead 9<a>, between which and the lead 9 electrical continuity thereby exists. But when a rheostat arm 16, Fig. 1, engages and depresses the stud 5, this continuity is broken and the current passes instead from the lead 9 to the arm 16, so that all the coils or circuits in connection with lead 9<a> are completely disconnected. An insulating washer is provided at 14. As applied to a wireless tuning-coil, Fig. 4, three such studs 20 - - 22 are fitted in addition to five plain studs 19, of which four are connected through a common lead 23 to one coil-end 24, and the fifth directly to the other coil-end. By means of the studs 20 - - 22, the coil is divided in four parts in series, the number in circuit being dependent on the angular position of the coil relatively to the brushes 31, and those not in circuit being entirely disconnected. In the position shown only one coil is in circuit, the remaining three being entirely disconnected by means of the brush 31 depressing the rod 4 of the contact 20. Fig. 4 shows an application to a series-parallel switch, wherein 34 is an arm, 42 is a plain contact and 35 a contact according to the invention. Coils 39 are connected to contacts 38 and the arm 37 is connected through lead 36 to the movable contact of the stud 35. In the position shown, the lead 32 is therefore dead, and the condenser in series with one coil. To place the condenser in parallel, the arm 34 is moved to stud 42 so that leads 32, 36 are connected together. By means of the arm 37 the number of coils 39 may be varied and those not in circuit are entirely disconnected with consequent elimination of dead-end effect. Other applications of the deviceare referred to in the Specification.

Title: Improvements relating to touch-adjusting means for typewriting and like machines
IPC: B41J5/26
Filed: 1938-02-04
Abstract: 498,955. Typewriters. REMINGTON RAND, Inc. Feb. 4, 1938, No. 3593. Convention date, Feb. 5, 1937. [Class 100 (iv)] Keys.-A returning-spring 25, Fig. 8, in connection with a sub-lever 20 or other pivoted member of a type-action is initially substantially radial to the pivot 21 of the sub-lever, and adjustment of the key-touch is effected by altering the inclination of the spring without stretching the spring, the arrangement providing an easy start for the key regardless of the touch-adjustment. In the preferred arrangement, shown in Figs. 4 and 8, each returning-spring 25 is connected at 26 to a sublever 20 and engages a hook 27 on a universal arcuate plate 28 secured to posts 35, 36 which pass through holes in brackets 41, 42 and are formed with grooves 59, 60 engaging lugs 58 on a supporting-plate 54 mounted on trunnions 55. The plate 28 is pressed by a spring 63 arranged on a screw 61 which is threaded into the bracket 42. Initially, the springs are substantially radial to the sublever pivots 21. By turning the screw, the plate 28 is moved rearwardly from the position shown to increase the touch, the inclination of the springs being altered without stretching the springs. Rearward movement of the plate 28 is limited by co-operation of a rib 28a thereon and the plate 54. Since it is desirable that the adjustment should be made by a mechanic, the head of the screw 61 is arranged in a relatively inaccessible position. To provide for a very light touch, the springs may be directed slightly to the rear of the pivots 20 when the plate 28 is in the forward position, the arrangement causing the springs to tend to lift the type-levers 23.

Title: Computing system
IPC: G05B19/05
Filed: 1978-01-30
Abstract: The arithmetic unit receives data, which may be derived from a memory or the inputs or outputs of the programmable control system itself, one bit at a time via a data input terminal (DATA-IN). In the arithmetic unit, this serial input data is logically linked to instructions which are fed in via corresponding terminals (START, RETURN, AND, CONNECT, INVERT, OUT). The circuit, or the functions triggered by the named instructions, are adapted to the representation of a specific control program in a so-called flow diagram, which symbolises a control program as make contacts and break contacts connected in series or parallel. The AND instruction, for instance, has the effect of closing such a break contact. The operation of the arithmetic unit is controlled by a clock signal, which is fed in at a clock input (CLOCK). The processed data leaves the arithmetic unit at a data output terminal (DATA-OUT). This arrangement allows flow diagrams of any processing depth and any processing width to be processed without redrawing the flow diagrams, and is particularly suitable for programmable control systems (PC). <IMAGE>

Filed: 1931-02-05
Abstract: 368,483. Turbine locomotives. HOLZWARTH, H., 7, Goethestrasse, Dusseldorf, Germany. Feb. 5, 1931, No. 3747. Convention date, Feb. 5, 1930. [Class 79 (i).] . A lay-out for driving a vehicle such as a locomotive comprises a turbine 13 driven by combustion products and a turbine 28 driven by steam produced by the waste heat of the combustion process. Gearing 30 connects the two turbines to a common lay-shaft 31. The combustion of primary fuel takes place in the explosion chamber 3 of a turbine 5 which drives through gearing 6 a compressor 7 for the combustion air which is drawn in at 8 and delivered by a pipe 9 to the explosion chambers. The exhaust from the turbine 5 passes by a conduit 10 and a heat-exchanger 11 to the turbine 13 from which it exhausts through a heat-exchanger 14. All parts of the explosion turbine are cooled by oil or other medium such as water or diphenyloxide, which is circulated by a pump 16 through pipes 17, 18 and a boiler 19. Steam for the second driving turbine 28 is derived from the heat of the oil in the boiler 19 in the following manner: feedwater supplied to a pipe 21 passes through a heat-exchanger 22 associated with the compressed air conduit 9, and then to the heat-'exchanger 14 whence it passes to the boiler 19. The steam generated here passes by pipe 26 to the heat-exchanger 11 where it is superheated before its entry into the turbine 28.

Abstract: 127,028. Caudron, R. Jan. 3, 1917, [Convention date]. Steering.-A device particularly applicable for the control of aeroplanes comprises means for controlling a mechanism from different points by acting either upon any one of the operating-members while the others are rendered inoperative, or by actuating several of the operating members simultaneously, at will. Fig. 4 shows a device for enabling either or both of two levers b<1>, b<2> to turn a shaft a<0> which moves the elevator. The levers b<1>, b<2> are connected by rods d', d<2> to sliding heads d<10>, d<20> in slots c<1>, c<2> in a plate c fixed to the shaft a<0>. The sliding heads d<10>, d<20> are connected by rods f<1>, f<2> to arms e', e<2> set at 120 degrees on a shaft e which has a pulley i geared by a cord to a pulley h loose on the shaft a<0>. The hub of the pulley h has an arm m connected by rods n to two levers k<1>, k' working over quadrants near the levers b<1>, b<2>. In the position shown, the lever b<1> is capable of moving the plate c, but the lever b<2> is inoperative. By moving either of the levers k<1>, k<2>, the mechanism may be set to render the lever b<2> operative and the lever b<1> inoperative, or both levers may be rendered operative together. By adding a third arm to the shaft e, a third slot in the plate c, and corresponding additional levers, the elevator may be controlled by any one lever singly or by two levers simultaneously. The slots in the plate c may be so arranged that those levers which are inoperative occupy an extreme forward position so as to leave a free space for the pilot or passenger. A modification is described in which the shaft e is carried by an extension of the member c and the pulley i is operated by Bowden mechanism. Other modincations are described in which the pulley is on a separate axle, and geared by cords and pulleys to the levers k<1>, k<2>.

Abstract: 1,213,726. Circuit assemblies. FERRANTI Ltd. 23 Jan., 1969 [26 Jan., 1968], No.4093/88. Heading H1R. In a circuit assembly 10 comprising a plurality of electrical devices 12 mounted on a substrate 11 and interconnected by signal conductors 13 a common metal conductive member 16 is arranged parallel to and spaced from the conductors 13 so as to form matched signal transmission lines. In the -embodiment shown four silicon wafers 12 are mounted on ceramic substrate 11, conductors 13 being of gold underlaid with a nickel chromium alloy, by gold pillars 15. Metal conductive plate member 16 is provided with mounting pillars 17 at positions where the electrical interconnections between plate 16 and signal conductors 13 are required and to form the transmission lines the plate 16 is positioned over the substrate and the pillars 17 bonded to the conductors 13 or pads 18. Portion 19 is connected to earth. The assembly is completed by potting, the potting material permeating between the plate 16 and conductors 13 to form a dielectric. The externally-extending leads 14 of the assembly are also in the form of matched transmission lines since they co-operate with portion 19 of plate 16 or with leads 22. Instead of using potting compound to form the dielectric the assembly may be in an hermetically sealed container, Fig. 4 (not shown), filled with a rarefied gas.
