Title: Improvements in fuel injection systems for internal combustion engines
IPC: F02M69/00
Filed: 1945-06-02
Abstract: 592,782. Changing the system of working. FISHER, I., FISHER, A. G. (Representatives of FISHER, A. D.), and MURASZEW, A. June 2, 1945, No. 13907. [Classes 7 (ii), 7 (iii) and 7 (vi)] In a fuel-injection system for a supercharged engine, the fuel is injected either through nozzles F directly into the cylinders or supplied by continuous injection through a nozzle H to the eye of the supercharger, manually or automatically controlled means P being included for selecting the direct or continuous injection system. Fuel is delivered by a pump C to an engine-driven metering and injection pump A which supplies the nozzles F or H according to the position of the valve P. On starting, the valve P is placed in the right hand position, and fuel flows from the pump C along a pipe M, through a non-return valve N and back along pipes O and R to a fuel tank B along with fuel flowing through the valve K<1>, thereby ensuring deaeration of the whole system. The non-return valve Q opens at a lower pressure than the valves H<1> and m so that in this position no fuel is injected through either of the nozzles H or F. For direct injection, the valve P is moved into the left-hand position in which the passage O is cut off from the pump A and the fuel is compelled to pass through the valve m to the nozzles F, excess fuel from the pump C continuing to pass around the circuit M, N, O, and R to keep these pipes primed. To change to continuous injection the valve P is moved to the central position, thereby allowing fuel to flow through the pipe O to the nozzle H and cutting off the return pipe R. The valve H<1> opens at a lower pressure (30-40 lbs. sq. in.) than the valve m (55-60 lbs. sq. in.) so that injection through the nozzles F ceases, re-circulation back to the pump C being prevented by the non- return valve N. An accelerator pump is interconnected with the valve P and operated in moving from the direct to the continuous injection system to discharge additional fuel through the nozzle H, thereby eliminating any lag in changing over. In a multi-cylinder engine each nozzle F is provided with a separate pump A, the various delivery valves K<1> feeding into a common pipe J leading to the valve P.

Title: Improvements in the control mechanism of reversible internal combustion engines
IPC: B63H21/22
Filed: 1944-07-24
Abstract: 581,523. Fluid - pressure servomotorcontrol systems. CROSSLEY BROS., Ltd., and CARTER, H. D. July 24, 1944, No. 14113. [Class 135] In a control mechanism for reversible internal combustion engines of the kind in which a gear operated pointer follows the movements of a hand-operated lever so that the two are in coincidence one behind the other when the control operation for which the hand lever has been set is completed, a control arm which actuates the control valve of a reversible servomotor controlling the reversing gear of the engine, is moved bodily without turning by the hand lever, and is subsequently turned to reset the control valve upon the movement of the gear operated pointer. As shown, the hand lever a and the pointer c are loosely mounted on a shaft e and are keyed to gears b, d respectively. The gear b meshes with a quadrant i having an extension i<1> in which a short spindle k is mounted. The control arm m is fixed to one end of the spindle k and a pinion n to the other end. The pinion n meshes with an idler gear o pivoted on the quadrant i. The quadrant i is mounted on the hub of a gear splined on a spindle g. The latter carries a second quadrant f meshing with the gear d and is coupled to a spindle h driven by the reversing gear. The idler o meshes with the gear j. The control arm m is connected by a suitable linkage p with the control valve of the servomotor. During the movement of the hand lever from the central or " stop " position to the " Run astern " position shown in Fig. 3, the spindle k is rotated counterclockwise due to the idler o meshing with the then stationary gear j and this compensates for rotary movement of the arm m due to movement of the quadrant i. With the quadrant i stationary, however, the gear j rotates the arm m clockwise through the gears o, n. Stops may be provided to limit the movement of the linkage p to half the total possible movement of the hand lever a so that a change over from " Run ahead" to "Run astern " position or vice-versa is impossible in one stage without waiting for the pointer to follow up the hand lever. According to the Provisional Specification the control valve is in the form of a rotary - cylindrical valve which is balanced as regards the supply pressure, the exhaust being through its hollow centre. The reversing gear may be operated manually by a hand wheel through worm gearing in which case the servomotor is disconnected by disengaging a hand-operated dog clutch.

Title: Improvements in or relating to releasable fasteners
IPC: F16B5/10
Filed: 1941-11-03
Abstract: 553,956. Cowling and like fastenings. DUNDAS, Ltd., R. K., KING, R. D., and WOOD, N. F. Nov. 3, 1941, No. 14154. [Class 44] In a fastening for securing an outer plate such as an aircraft cowling to an inner part and of the kind in which a stud member mounted on the plate engages in a socket on the inner part, for example as described in Specification 553,953, the stud member is provided with means whereby it may be manipulated for release without the use of a separate tool and is associated with means providing normally a flush outer surface to the fastening, this means being displaceable to enable the stud to be manipulated. Figs. 1, 2 show a form in which the stud member 2 has an extension 3 projecting into a socket 4 permanently mounted on the plate 1, a rubber member 5 being shown as engaging the inner face of plate 1 and a groove in socket 4 to retain the socket in place. The outer end of part 3 has pivoted thereto by lugs 7 and pin 8 a disc 6 which is normally held flush with the outer face of plate 1, Fig. 1, by a spring 10 and washer 11, the latter bearing against flats on the lugs. To effect release the disc is tilted to the position shown in Fig. 2 in which it serves as a finger piece for rotating stud 2. The Specification describes the use of a spring member or spring- pressed member engaging cams or recessed lugs on the disc member to retain it in normal position in place of the arrangement 10, 11 shown, the spring in one form being provided by a rubber washer. Modifications are also described in which disc 5 is replaced by two half-discs, one being depressed to project the other above the surface of plate 1 so that it may be grasped and raised further to the stud manipulating position. Fig. 7 shows a form in which the stud 2 carries a thumb-piece 20 projecting into a slot in a disc 21 held up to the flush position shown by spring 22. To release the fastening, plate 21 is depressed so that part 20 may be grasped. In one modification plate 21 is replaced by a slotted rubber disc secured across the mouth of socket 4 and in another socket 4 has a sponge-rubber filling-piece. Fig. 14 shows a form in which a disc or button 33 is held in a seating at the mouth of a socket formed in the stud 2 by a tension spring 35 housed in the socket. The button may be pulled out and inserted edgewise in slots 37 to enable stud 2 to be rotated. In a further form the stud is not rotatable, but has a tapered and shouldered end snapping into engagement with spring members on the inner part. A cam on the back of a pivoted flush closure disc depresses a spring plunger when the disc is tilted, a ring on the plunger spreading the springs to release them from engagement with the stud.

Filed: 1924-06-13
Abstract: 217,602. British Thomson-Houston Co., Ltd., (Assignees of Rask, L.). June 14, 1923, [Convention date]. Exciting; alternating-current induction machines.-In an electric ship propulsion system a number of generators are arranged to supply a greater number of motors each driving a propeller shaft, and in a triple screw ship the middle propeller is arranged to run at the mean speed of the outboard propellers when these are running at different speeds. A generator 3 supplies power to a single-fed induction motor 5 through a switch 8, forward running switches 10, 11 and polechanging switches 13 or 14, switch 13 giving 24 poles and switch 14 giving 16 poles. A second generator 4 similarly supplies a motor 6 through switches 20, 22 and 24 or 25. In both cases reverse motion is obtained through switch 9 instead of 11 and switch 21 instead of 22. The middle motor 7 of the double-fed type has its stator 17 supplied from the generator 3 through a switch 16, which is operated with the switch 11, and its rotor 29 is connected through a switch 27, which is operated with the switch 22, and the switch 25 to the generator 4. When the motor 6 is running at slow speed, the secondary 29 is shortcircuited through part of switch 24. During reverse running, the motor 7 is inoperative. The various switches are operated by reversing controllers 12, 23 and pole-changing 'controllers 15, 26 and each reversing controller may be mechanically interlocked with its pole-changing controller so as to prevent reversal in the high speed motion. The switches 13, 14, 24 and 25 may be controlled by a cam-shaft. In a modification switches are provided for short-circuiting both or either the rotor and stator of the motor 7.
