Title: Liquid fuel supply pumps for engines
Inventor: FREEMAN FRANK GEORGE
IPC: F02M41/08
Filed: 1956-02-22
Abstract: 821,323. Speed governors; gas turbine plant. LUCAS (INDUSTRIES) Ltd., J. May 9, 1957 [Feb. 22, 1956], No. 5515/56. Classes 57 and 110 (3). [Also in Group XXVIII] A swash-plate pump (see Group XXVIII), for use on continuous combustion engines, is driven from the engine and is provided with means to increase the fuel supplied by the pump when starting the engine and a centrifugal governor for controlling the fuel supplied during normal running. A lever 21, Fig. 1, is normally urged against a stop by a spring 26 and is moved, on starting the engine, against the spring action to abut a second stop 24, this movement being transmitted through a forked lever 22 to increase the pump output by tilting the swash-plate 12 (as shown in the Figure). On releasing the lever 21 it moves under the action of spring 26 and the swash-plate is moved to its position for normal running. A spindle 30 rotating with the cylinder block 10 of the pump carries a part 29 of the centrifugal governor, another part 28 being pivotally connected to the part 29 by a blade spring 32, the two parts being interconnected by a spring 31. The governor part 28 abuts, through an intermediate thrust piece 33 against a lever 34 which is pivoted by a spring 36, Fig. 2, attached to the housing while the other end has formed on or attached to it a valve closure member 39, the lever being loaded by a spring 37. When the speed of the engine exceeds a predetermined value the governor part 28 moves in a plane containing the axis of rotation about pivot 32 and this movement is transmitted through the part 33 to the lever 34 which moves about pivot 36 against the action of loading spring 37 causing the valve member 39 to open a by-pass conduit to by-pass some of the pump delivery which passes through passages in the thrust piece 33 to provide lubrication.

Filed: 1960-02-16
Abstract: 928,231. Spring power-storing mechanisms. W. G. HOLLOWAY. Feb. 16, 1960, No. 5518/60. Class 10. [Also in Group XXIV] An energy-storing device comprises an input and an output coupling member mounted for relative rotation on a shaft, one or more elastic cords or helical coil springs secured at opposite ends to the coupling members and a cage arranged concentrically around the shaft, which cage comprises a plurality of spindles fast with the input coupling member and each being provided with rollers, the arrangement being such that the input coupling member drives the output coupling member through the cords or springs, which should the input exceed the output requirments, are stretched around the cage so as to store energy which is released when the input is less than required. An energy-storing device comprises input and output coupling members 1, 2, Fig. 1, mounted for relative rotation on a shaft 3 and having the opposite ends of an elastic cord 8 or coil spring attached thereto by clamping devices 9. The cord 8 is mounted about a cage arranged concentrically around the shaft 3, which cage comprises spindles having rollers 12 to form a frictionless surface, the spindles being secured to flanges 7, 11 of a sleeve 6 of the input member 1. The input member is rotated by means 15 and ratchet 16 to drive the output member 2 through the cord at a controlled rate by means (not shown) any excess input being taken up by the cord being stretched around the cage. Stops 13, 14 on the members 1 and 2 respectively limit relative rotation therebetween. In a modification, Fig. 4, a second cage is mounted concentrically around the cage, the outer ends of the spindles of the outer cage being fixed to an annular flange ring 17 in an annular recess 18 of the output member 2 and the outer ends of the spindles of the inner cage being attached to a flange 19 of a sleeve 20 mounted on the shaft 3. The input member is driven by a pinion 21 on the sleeve 4 through a chain or gear 22 and a further pinion 23 on the sleeve 4 is engaged by a ratchet mechanism 26. The output drive is via a pinion 24 on the flange 5 through a gear 25 and a ratchet 26 controlled by a brake 27 controls the output member. A plurality of cords 8 are provided for each cage and are attached at opposite ends to the input and output members. A mechanism for controlling the output member and the release of stored energy comprises a variable speed gear-box .38, Fig. 5, controlled via sleeve and pinion members 28, 29 associated with input and output members respectively which rotate on stub axles 30, 31 on a frame 32 to which the shaft 3 is secured. The members 28, 29 support an externally screw-threaded shaft 33 so that differences in rotation of the members causes the threaded shaft to be exchanged between them so as to cause movement of a rocker arm 37 controlling the gear-box 38 via a wheel 34 on the shaft 33 and an associated block 35 which is slidably mounted on a spline 36.

Title: Improvements in and relating to Wireless Signalling Systems.
IPC: H03C1/16
Filed: 1917-04-19
Abstract: 127,325. British Thomson - Houston Co., (General Electric Co.) April 19, 1917. Wireless telephony; electric oscillations, producing.-The inductances of the plate and grid circuits of a vacuum-tube oscillation generator are arranged in series in the aerial circuit, the aerialearth capacity thus forming an electrostatic coupling between the plate and grid circuits. The amplitude of the oscillations may be controlled by applying potential variations of audible frequency to the grid, which variations are amplified by the tube and are returned to the grid circuit by a transformer. The supply source for the plate circuit may be arranged in series with .an inductance as a shunt across the plate and filament. As shown in Fig. 2, three tubes 4 are arranged in parallel, with a battery 31 and choke coil 30 connected across the grids 3 and filaments 1, and a source 6 and inductance 25 connected across the plates 2 and filaments 1. The grid circuits comprise grids 3, condensers 29, 28, 27, inductance 8, and filaments 1, and the plate circuits include plates 2, condensers 26, 21, inductance 5, and filaments 1. These circuits are coupled electrostatically within the tubes, and inductively by the common magnetic field of the coils 5, 8; and as both coils 5, 8 are in series in the aerial circuit, the aerial-earth capacity also constitutes an electrostatic-coupling. The frequency of the oscillations produced is regulated by varying the inductance 15 or a capacity in the aerial. The amplitude of the oscillations is controlled by a circuit in which the current is varied at audible frequency, for example by a microphone 17. This circuit is connected by a transformer 19, 9 to the grid circuits, and the potential variations of the grids are amplified in the plate circuits and are returned to the grid circuits by the transformer 20, 10, which thus acts as an audible-frequency coupling between the plate and grid circuits. The audible-frequency transformers may have iron cores, and are shunted by condensers to afford a path for the high-frequency currents. A single tube only may be employed, and the source 6, shunted by a condenser, may be in series in the plate-filament circuit. The filaments are heated by a source 24. Reference has been directed by the Comptroller to Specification 107,001.
