Title: Electronic fuel injection systems
IPC: F02D41/04
Filed: 1972-08-03
Abstract: 1334039 Electrical fuel injection systems for I C engines GENERAL MOTORS CORP 3 Aug 1972 [27 Aug 1971] 36234/72 Heading G1N In an I.C. engine intermittent fuel injection system, an inductive transducer 100 having an inductance variable with engine air intake pressure is charged and subsequently discharged in synchronism with engine rotation, the charging voltage determining the injection pulse duration in such manner that, when the engine speed is above a predetermined value, the amount of fuel injected decreases with increasing engine speed and with increasing intake air pressure. As shown, the inductive transducer 100 includes a coil 106 and a core 108 movable in dependence upon air intake pressure. A trigger pulse former 164 provides pulses in synchronism with engine rotation, each pulse causing the coil to be charged via resistors 102, 104 to provide a charging voltage A1, Fig.4, the slope of the voltage being determined by the resistances of resistors 102, 104 and the inductance of coil 106. When the voltage A 1  falls to a predetermined level L r ', a transistor 116 is rendered conductive and the coil 106 discharges via resistor 104 and the conductive transistor 116, to provide a discharge voltage As whose slope is determined by the resistance of 104 and the inductance of 106. An injection pulse C is provided during the voltage A 1 . Figs.4a and 4h represent the voltage diagrams which occur at two different speeds above the predetermined engine speed. As can be seen, at the higher speed, Fig.4b, the amplitude M 2  of the voltage A 1  above the reference level L' r  is smaller than at the lower speed. This is due to the negative-to-positive voltage jump being of the same amplitude at all engine speeds, and a greater portion of the amplitude being below the reference level at higher speeds. Fig.4c represents the voltage diagram which occurs at the same speed as that represented in Fig.4b but at a higher intake pressure. In this case the slopes of the curves are shallower due to the increased inductance of the coil 106.

Abstract: 1,094,924. Knitting-machines. BENTLEY ENGINEERING CO. Ltd. Sept. 14, 1964 [Sept. 20, 1963], No. 37105/63. Heading D1C. In a circular knitting-machine a control drum is racked by pawls at a selected stroke or strokes during a period of activation of the pawls. The pawls 6, 7 are activated by a bit on the pattern chain and are driven to rack a ratchet wheel 5 fixed to the control drum. Projections 9 on a wheel 8 also rotating with the drum raise bars 2-4 which bluff the pawls via a link work 11-17. The bars are retracted in sequence from the projection engaging position so that they are available in turn for bluffing the pawls. The bar 1 may be raised to bluff the pawls and prevent rotation of the drum until the following period of activation.

Title: Microwave gyromagnetic latching switch
IPC: H03K17/82
Filed: 1965-08-31
Abstract: 1,116,953. Microwave switches. WESTING- HOUSE ELECTRIC CORPORATION. 31 Aug., 1965 [14 Sept., 1964], No. 37130/65. Heading H1W. A microwave switch comprises a gyromagnetic element arranged in a waveguide and means for producing closed-loop magnetization of the element in planes parallel to the direction of propagation, the magnetized volume of the element being such that it produces a high reflective impedance (when magnetized) over a certain band of frequencies. The effect is produced at field strengths below that necessary to cause gyromagnetic resonance. As shown, the means for producing the required magnetization consists of a current-carrying conductor 53 which passes back and forth in transverse directions through an elongated ferrite block 51 arranged symmetrically within the guide. The effect is reciprocal and is independent of the direction of the current. The block may also be magnetized in transverse planes by a further conductor 62 passing axially through it. Such magnetization produces a condition of transparency. By means of the switching system shown, the two wires may be connected in series and the same current passed through them. It is stated that, in this case, for one direction of the current the block is transmissive and for the other direction it is reflective. The current may be reversed by means of the commutator 70. If a ferrite having a square-loop hysteresis characteristic is used, the device may be operated by current pulses and holding currents are unnecessary. A modification of restricted bandwidth is described (Fig. 1, not shown), in which the ferrite element is in the form of a cube and the conductor 53 passes through it only once.

A high-voltage electric power cable has insulation comprising an oil-impregnated permeable helical wrapping of laminated tape consisting essentially of a thin porous strip of cellulosic paper bonded to an oil-impervious polymer film, the wrapping having slight fissures between adjacent turns of tape thus providing helical passages which allow easy penetration of oil throughout the wrapping. The fissures may be obtained by using tape having equal widths of paper and polymer and winding with a slight overlap between adjacent turns or by winding with a small gap between the edges of adjacent turns, or alternatively by using a tape in which the polymer strip is slightly narrower than the paper component when the tape may be butt wound. The wrapped conductor is vacuum dried in an impregnating tank in which it is then submerged in a liquid impregnant and subjected to alternate pressure and vacuum cycles to ensure complete saturation. A protective sheath is then applied over the cable. The polymer used in the tape is selected from P.T.F.E., polypropylene, polycarbonates, polythene, and copolymers and interpolymers thereof. Impregnants mentioned are hydrocarbon oils such as naphthenic based mineral oils, and silicone fluids such as polysilicate esters and polysiloxanes. Polysiloxanes specified are dimethyl-, methyl phenyl-, and diphenyl-polysiloxanes.
