Title: Solid state switch
IPC: H01L29/749
Filed: 1971-09-13
Abstract: 1325108 Transistor switches MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 13 Sept 1971 [14 Sept 1970] 42635/71 Heading H3T A solid-state switch comprises a voltage controlled thyristor Q 1  having an insulated gate electrode and triggered by a voltage applied to the gate electrode, a transistor Q 2  having an emitter or collector electrode connected to the gate electrode of Q 1  and an arrangement, e.g. an applied voltage V, for controlling the emitter base current of Q 2 . In operation, Q 1  is turned on by grounding the base of Q 2  when it is rendered conductive to apply a voltage V present at the emitter to the gate electrode of Q 1 . As the applied gate voltage is held by Q 1  even after Q 2  is turned off, the base of Q 2  is once again grounded with the voltage V not applied to the emitter so that the gate voltage is reduced for turning Q 1  off. The thyristor Q 1  has an NPNP structure with an insulated gate electrode (Fig. 2, not shown).

Title: Combined fuel injection and ignition system for internal combustion engines
IPC: F02P3/12
Filed: 1962-11-15
Abstract: 1,003,050. Ignition systems; fuel injection systems; fuel injectors; sparking plugs. HERMANN PAPST. Nov. 15, 1962 [Nov. 15, 1961], No. 43195/62. Heading FIB. [Also in Division H2] In combined fuel injection and ignition apparatus for internal-combustion engines in which the ignition current is generated by piezo-electric means, a pressure capsule arranged to exert pressure upon a piezo-electric body generating the ignition current is exposed to the pressure arising within a fuel supply tube extending between a fuel injection pump and an injection nozzle comprising a spark gap for the ignition current whereby the fuel injection pump actuates the piezo-electric generator. Thus in Fig. 1 the piezo-electric generator 14 is operated by fuel pressure supplied to it through the passage 11 in a ceramic member 8 which forms part of the fuel injector. A ring type electrode 25 which may be of nickel or tungsten is welded to the part 28. The member 24 serves as the central electrode. Fig. 5 shows a modified piezo-electric generator pressure chamber. In Fig. 6 the piezo-electric generator is combined with the fuel injector. In some cases it may be advantageous to use a nozzle with a valve. After the valve has opened its insulated movable part will serve as a central electrode.

Abstract: 940,718. Valve and transistor amplifying circuits. MINISTER OF NATIONAL DEFENCE OF H.M. CANADIAN GOVERNMENT. Dec. 29, 1959, No. 44121/59. Headings H3W and H3T. [Also in Division G4] Non-linearity in the transfer function of a transmission circuit is compensated by preceding the circuit with a network comprising two series connected varistors arranged as a potential divider and at least one linear element, the linear element being such as to cause the network to have a transfer function complementary to that of the transmission circuit. As shown in Fig. 4, unsymmetrical varistors W1 W2 are connected oppositely poled in series with a resistor R across the input terminals I, with the junction of the two varistors connected to the input of a triode valve stage T, whose non-linearity is to be compensated. The non- linearity may be adjusted by selecting the varistors or by adding shunt and series resistors, Fig. 4a (not shown). Non-linearity in a transistor amplifier may be similarly compensated.

Title: Plural beam electron gun for a color picture tube
IPC: H01J29/51
Filed: 1968-09-18
Abstract: 1,223,584. Colour television tubes. SONY CORP. 18 Sept., 1968 [20 Sept., 1967], No. 44316/68. Heading HID. In a colour television tube using red, blue and green phosphors the blue phosphor saturates at a lower beam current density than the other two phosphors and thereby limits the brightness of the picture if the white balance is to be preserved; this difficulty is avoided by defocusing the blue beam so that the maximum beam density gives greater apparent brightness for each blue spot. In Fig. 3 the triple electron gun has a common control grid G wherein the aperture glB for the blue beam is of greater diameter than the other two apertures. The cathode K B  for the blue beam is spaced from the grid by a distance d 1  substantially greater than the spacing d 2  of the other cathodes; this has the effect that the cross-over for the blue beam lies outside the object plane of an electrostatic focusing lens common to the three beams. Alternative arrangements use separate cathodes with separate control grids (Figs. 5 and 6, not shown) or a common cathode with separate control grids (Figs. 7 and 8, not shown). As described the gun is applied to a tube using coplanar beams, the outer beams being converged at the plane of a beam selecting grid or mask by a fixed deflecting system (Fig. 1, not shown).

Title: Improved device for effecting the narrowing in knitting machines
IPC: D04B9/20
Filed: 1960-12-28
Abstract: 938,506. Knitting machines &c. FABRIQUE NATIONALE D'ARMES DE GUERRE S.A. Dec. 28, 1960 [Jan. 5, 1960; Dec. 12, 1960], No. 44387/60. Class 74 (2). A narrowing device for a rotary bed circular knitting machine comprises a curved frame 13 concentric to the needle cylinder 43 having knitting cams 16, 17, 18 on its interior surface for engaging the butts 19 of needles 20 and a shaped guide 15 on its exterior surface for a pair of picker arms 35 the ends 36 of which cooperate with the cams 16, 17, 18 to control the needles for narrowing operations. The picker arms are pivoted at 34 on pivot pins 31 to allow up and down as well as horizontal swinging movements and are interconnected by a rod 40 so that only one of the pickers can be in operative position at the same time. Normally with the needle cylinder rotating anti-clockwise continuously the right-hand picker arm is inoperative and the machine knits over the whole periphery of needles. If a narrowing operation is to be performed the needle cylinder is given an oscillating rotary motion of constant amplitude so that at each reversal of movement the butt of the first needle is engaged by the respective picker arm 35 which will be in operative position to raise the needle so that it does not pick up a thread, or form a stitch, the operative picker arm 35 then swinging to its inoperative position and moving through rod 40 the other picker arm to operative position ready for the next reversal of movement. To effect a widening operation a widening mechanism which brings two needles back into operation every reversal of movement of the needle cylinder must be employed to compensate for the continued action of the narrowing operation.
