Title: Fuel control for internal combustion engines
Inventor: FROGGATT ALFRED WALTER
IPC: F02D1/00
Filed: 1956-11-03
Abstract: 833,771. Starting fuel injection engines. RUSTON & HORNSBY Ltd. Oct. 9, 1957 [Nov. 3, 1956], No. 33608/56. Class 7(3) The movement of a governor rod 15, Fig. 1, controlling a fuel injection pump control rod 13, in the increased fuel supply direction is limited during normal running by a stop 17 against which a collar 20, transmitting the force of the main loading spring 23 to the rod 15, abuts a weaker spring 14 serving to move the rod 15 relative to collar 20 beyond the normal maximum supply position to a starting position when the governor is stationary or rotating at starting speed. The spring 23 acts through lever 24 on the collar 20 which normally abuts shoulder 21 on the rod 15 but which is slidable relative to the rod 15 through a distance limited by a circlip 22 which determines the starting supply position of the rods 13, 15. When, due to increased load, the engine speed decreases, rod 15 is moved to the right until at idling speed collar 20 contacts stop 17. At idling speed the force of the governor 16 is sufficient to overcome spring 14 but when the engine is stationary or rotates at starting speed, below idling speed, spring 14 overcomes the governor force and moves rod 15 to the right to the excess supply function in which circlip 22 contacts collar 20. After starting the governor 16 moves member 15 back until it contacts collar 20 and comes under the control of the main spring 23. In a modification, Fig. 4, the rod 15 is replaced by a sleeve 25 on the end of which a cap 26 serves the function of the circlip 22. The stop 17 is also replaced by an adjustable stop 28 cooperating with the lever 24 and the force of spring 14 is applied through a lever 27.

Filed: 1975-08-14
Abstract: 1515567 Semi-conductor devices INTERNATIONAL RECTIFIER CORP 14 Aug 1975 33985/75 Heading H1K A method of forming spaced PN junctions (51, 52), Fig. 11 (not shown), e.g. of a thyristor, comprises the steps of differentially diffusing Groups III-V impurities, preferably in the form of an inorganic compound and a corresponding Group III element, in a single crystal silicon wafer 25, Fig. 6, through a SiO 2  diffusion mask and a window 27 therein; stripping the SiO 2  mask thereby removing a surface layer of the wafer which might have been damaged due to mechanical lapping; redepositing the SiO 2  layer to entirely cover the wafer; and then in a drive-diffusion step, heating the oxide coated wafer to vary distribution of the impurities in the wafer, Fig. 8, the concentration of the Group III impurity in the wafer varying due to its out-diffusion into the oxide layer. The simultaneous diffusion of, e.g. Ga and As, carried out in a sealed chamber (20), Fig. 1 (not shown), in an inert atmosphere produces a P-type shell region 30 enveloping an N-type core region 31, and an N-type region 32 below the window 27 since the side coating 26 is permeable to Ga and not to As. In order to complete the wafer for use as a thyristor, the window 27 is widened by etching to expose the region at which the boundary of the N-type region 32 intersects the upper surface of the wafer, and layers (40, 41), Fig. 11 (not shown), of nickel and gold, respectively, shorting the regions 30, 32, are provided over the region exposed by the window. The periphery of the wafer is then sand-blasted to cut the edges of the region 31 and thereby provide two isolated PN junctions (51, 52). An aluminium gate lead (60) and a molybdenum or tungsten anode electrode (61) are provided.

Filed: 1960-10-07
Abstract: 915,969. Liquid-pressure engines. GROVER SMITH MANUFACTURING CORPORATION. Oct. 7, 1960 [Oct. 8, 1959], No. 34493/60. Class 69 (2). [Also in Group XXVI] In a fluid pressure-operated motor comprising a cylinder 30 and a reciprocating piston 45, Fig. 2, an automatic valve mechanism 32 provided with inlet 81 and exhaust 84 is disposed at one end of the cylinder, and a tube 47 mounted on the piston opens at one end into the cylinder on the side of the piston remote from the valve mechanism and at the other end into the valve mechanism. The latter includes concentric sleeve valves 66, 67 encircling the tube 47 and movable axially relative thereto, the valve 67 being provided with ports 75, 76 coacting with ports 61, 62, 63 in the stationary part of the mechanism, and a plurality of fluid passages extending from the inlet 81 and exhaust 84 to the adjacent end of the cylinder and the interior of the tube 47 and controlled by axial movement of the piston 45 and valves 66, 67 to provide fluid flow alternatively to each side of the piston while permitting exhaust of fluid from the opposite side. The lower end of the tube 47 is threaded into a fitting 48 provided with radial passages 49 and forming with a bushing 50 a lost-motion connection between the piston 45 and the pistonrod 20 of a lubricant pump 16. The upper end of the tube 47 has lost-motion connection through bushing 54 and spring 91 with the valve 67. In operation, with the parts positioned as shown in Fig. 2, pressure fluid entering at 81 passes through annular chamber 85, groove 59 and passage 83 into the top of cylinder 30. As piston 45 is moved, fluid in the lower end of the cylinder escapes through passages 49, tube 47, ports 76, chamber 86 to outlet 84. Escape of fluid through ports 76 continues until through movement of the sleeve 67 by the tube 47 the ports are cut-off by the valve 66. Continued movement of the piston compresses the trapped fluid which, on ports 76 being uncovered, passes into the annular chamber 93 and, as the pressure increases, reverses valve 66 whereby pressure fluid passes through chamber 93 and ports 75, 76 through valve 67 and tube 47 into the lower end of cylinder 30 to move piston 45 upwardly, fluid in the upper end of the cylinder escaping through passage 83, groove 59 and chamber 85 into exhaust 84. Towards the end of its upper stroke, as shown in Fig. 4, piston 45 moves valve 67 whereby ports 76 are first cut-off and then put into communication with chamber 86 so that pressure in the latter increases and co-operates with spring 90 to reverse the valve 66 to its original position shown in Fig. 2. A port 77 is provided in tube 47 for assuring reversal of valve 66 to re-start the motor if the latter has been stopped for a prolonged period with the piston at the lower end of its stroke.

Filed: 1977-08-17
Abstract: A fixed part of a clutch (1) comprises a magnet body (2), a permanent magnet (3), a coil of an electromagnet (5) and a nonmagnetic insert (4). An armature (19) comprises an armature disc (12) which is made up of two concentric rings and is connected firmly in terms of rotation to a driver (18) via an annular spring (11). Between the fixed clutch part (2, 3, 4, 5) and the armature (19) there is an axially fixed but rotatable clutch disc (15) which has a deflector (8), a nonmagnetic intermediate layer (9) with an insert (10) and a hub (17). A nonmagnetic intermediate layer (16) is arranged in the hub (17), concentrically to the axis of the hub. In the deenergised condition of the coil of the electromagnet (5), the magnetic flux lines of the permanent magnet (3) follow a path (26). In the excited condition of the coil, the magnetic flux lines follow a path (22) while the flux lines of the electromagnet (5) follow a path (21). The nonmagnetic intermediate layer (16) and the nonmagnetic insert (4) reduce the magnetic leakage flux to a minimum. A fail-safe clutch or brake with a high torque and a short response time and with small dimensions is thus created. <IMAGE>
