Title: Diesel engine glow plug control
Inventor: CASSANI STEFANO
IPC: F02P19/02
Filed: 2009-07-17
Abstract: A method for using a glow plug 32, 34, 36, 38 in a diesel engine 134 comprises a first step of providing an electrical energy source, eg battery 52, for supplying an electrical current through the glow plug 32, 34, 36, 38, a second step of measuring the electrical current, a third step of calculating a voltage across the glow plug using the measured value of the current, and a fourth step of controlling the electrical current through the glow plug using the calculated voltage. Voltage may be measured across a monitoring resistor 70-76 connected between the battery 52 and the glow plugs 32-38. The pulse-width of the current through the glow plugs may be controlled. Controlling the current allows accurate regulation of the heating of the glow plugs because although the wiring harness causes a voltage drop the current remains the same. Variations in current reflect variations in resistance such that variations in the resistance of the glow plugs and the voltage drop due to the wiring harness can be compensated.

Abstract: 495,255. Making wire ropes; drawing; rolling. CALLENDER'S CABLE & CONSTRUCTION CO., Ltd., and HARRIS, G. M. April 9, 1937, Nos. 10141/37 and 4967/38. Addition to 476,863. [Class 109] [Also in Group XXII] The invention described in the parent Specification for making compacted wire strands is applied to the manufacture of such strands consisting of a single layer of wires preferably four. The interior of the compacted strand, when hollow, may be filled with a rubber or bituminous compound or with like mouldable material. Wires 7 are delivered from bobbins 6 carried on a carriage 4 which is keyed to a rotating shaft 1 and supported by rollers 5. Each bobbin 6 is rotatably supported in a frame 9 and has a crank lever 10 connected at its lower end to a weighted ring 11 so that each lever is maintained vertical. The wires are deformed by rolls 31, Fig. 5, one of which may be grooved, or by a die 14 and a spring-pressed mandrel 18 slidable in an adjustable holder 19, or, as shown, by a combination of these devices. The wires are stranded in the throat of the die 14, and the strand is further compressed in a die 21, which may comprise a die 23 and rolls 24 and is rotated by a chain 27 when a prespiralled strand of non-circular cross-section is required. A capstan 22 draws the strand and wires through the machine. Other combinations of dies and rolls, which may be driven, may replace those shown. Wires 7A, Fig. 6, initially of circular section are separately deformed to the section 7B, and are further circumferentially compressed to the section 7C during stranding. Further compression of the strand in the die 21 deforms the wires to the section 7D. Similar stages are shown in the production of strands of non-circular section and for strands of hollow or closed final form. A filling 30, Fig. 11, of unvulcanized or partly vulcanized rubber or other material is delivered to the interior of the strand from a reel 29 through a bore 38 in the mandrel 18 and is compressed therein in the successive stages. One or more wires 35 may be embedded in the rubber. An outer layer of rubber may be applied, and the core and covering vulcanized in one operation.

Filed: 1954-04-12
Abstract: 767,315. Radio navigation. WAECHTLER, M. April 12, 1954 [April 13, 1953], No. 10646/54. Class 40(7) A vehicle is provided with a twin channel direction finder in which signals from crossed aerial loops are fed respectively to the deflecting means of a cathode ray tube indicator arranged so that bearings are indicated by radial or diametric lines on the tube screen, Fig. 1 (not shown). Two or more omnidirectional beacon transmitters operating on the same frequency are keyed sequentially to enable the various beacon bearings to be determined. The keying is done sufficiently fast for all the indications to be visible at once on the indicator. A course line may be defined by having two transmitters 6 and 7 aligned with the desired course 8 and the vehicle steered so that the two bearing lines are brought into co-incidence as indicated at 9, 10 and 11, and then maintained in co-incidence. When using the arrangement to guide a vehicle along a path between two obstructions two additional transmitters maybe mounted on the obstructions to show the limits of the path and the desired course appears as the bisector of the angle between the limiting bearing indications from these beacons. Three beacons give a position fix when the angles between pairs of bearings are entered on a map.

Abstract: 943,797. Fluid-pressure servomotor control systems. HOLLEY CARBURETOR CO. March 28, 1960, No. 10847/60. Heading G3P A fluid pressure servo computing device comprises movable pressure responsive means, a moment arm,resilient means connected to the pressure responsive means for applying a reference force at various points along the moment arm, the moment arm being sloped relative to a surface parallel to the axis of the pressure responsive means so as to provide for a change in the magnitude of the reference force in accordance with the point along the arm at which it is applied, a valve operatively connected to the arm for varying the magnitude of the pressure acting on the pressure responsive means, and means for directing a force input to the arm for actuating the valve. In an engine fuel control system the engine fuel control valve 62 is actuated by a rack and pinion 58, 60 the rack of which is given a linear movement in response to changes of engine speed. The engine, in the preferred embodiment a gas turbine engine, has a governor type speed detector 122 which acts on a lever 110 pivoted at one end 112 and carrying at the other end a balanced leak-off valve 116 which cooperates with a seat 120 at the end of a passage 144 connected by a passage 148 to one side of a differential area piston 46 the other side of which receives a reference pressure. The piston 46 has an extension 56 having indentations 94, 96 which receive the ends 90, 92 of two levers 76, 78 the other ends of which are urged apart by a spring 88. The lever 76 carries a roller 80 which rides a rigid guide plate 98 and the lever 78 carries a roller 82 which rides along the inclined upper surface 114 of the lever 110. The arrangement is such that when the lever 110 is moved by the governor 122 the resulting movement of the leak-off valve 116 alters the pressure in the chamber 50 so that the piston 46 moves. As the roller 82 rides the surface 114 the thrust exerted by the spring 88 varies and the piston movement ceases when this thrust balances that of the governor. The piston movement is transmitted via the rack and pinion 58, 60 to the fuel metering valve 62. Specification 943,798 is referred to.
