Title: Telephone outpulser circuits
IPC: H04M1/31
Filed: 1973-07-03
Abstract: 1404078 Impulse transmitters STANDARD TELEPHONES & CABLES Ltd 3 July 1973 31612/73 Heading H4K An impulse transmitter comprises a first transistor connected in series with the loop and a second transistor connected to the first one so as to turn it on and off in accordance with a pulse train supplied thereto by a digit store which is filled by a subscriber keyboard. The first transistor may consist of a Darlington pair. The store MOS is of integrated circuit form utilizing MOST technology and has provision for up to 18 digits. A capacitor C and a Zener diode ZD1 which are fed from the line via a protective rectifier bridge PC serve as a local power source. A relay driven by the pulse output from the store acts as an off-normal switch via its contacts RLB1, RLB2. The keyboard enters digits into store in binary coded decimal form. Fig. 2, depicts the impulsing circuit IMP. The store and related circuitry are notionally represented by box B. Normally transistor TR1 and FET TR2 are conductive but are turned off in response to the energization of transistor T3 at each pulse supplied by the store. In an alternative arrangement (Fig. 3, not shown) the FET is replaced by a PNP transistor and the pulsed transistor is turned off by each pulse emitted from the store. The latter determines the interdigital pause.

Title: Tuning indicator system
IPC: H03J3/14
Filed: 1946-10-26
Abstract: 635,064. Valve circuits for radio reception. HAZELTINE CORPORATION. Oct. 26, 1946, No. 31830. Convention date, Oct. 29, 1945. [Class 40 (v)] The sensivity of the tuning indicator of a wireless receiver is varied inversely with the strength of the received signal by means of a control voltage which varies less rapidly with the amount of mistuning than the main tuning indicating voltage so that a clearer indication is obtained on weak signals. As shown in Fig. 5, the control electrode 45 of tuning indicator 19<1> is fed from the D.C. output of diode 51 which rectifies the carrier frequency voltage from the I.F. amplifier 15 and developed across a sharplyselective filter 49. The anodes of the tuning indicator receive their H.T. supply from the screen grid of an I.F. amplifier valve 34 which voltage increases as a signal is tuned in due to the action of the A.G.C. voltage which is applied to the control grid 35 through a resistor 39. The control exercised by the indicator control grid with a given amount of mistuning is greater than that of the anode due to the action of filter 49 and by suitably proportioning the voltages a constant indication can be obtained with signals of widely different strengths. Further, the change of indicator anode voltage produces a change of target brightness giving an indication of signal strength. In an alternative arrangement, Fig. 1, the indicator has two control grids 24, 25, and is adapted for use in an F.M. receiver by feeding the grids with the oppositely-varying outputs from the anode and screen grid 27, 26 of an amplifier valve 2 produced by applying the D.C. output from the discriminator 16 to the suppressor grid 30 of the amplifier valve. In a further arrangement (Fig. 7, not shown), a moving coil indicator is used, the fixed coil being connected in series with the cathode of a valve controlled by A.G.C., and the moving coil fed with the more rapidly varying tuning indicating voltage. Specification 513,859 is referred to.

Abstract: 864,584. Two-part couplings. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Sept. 15, 1959 [Oct. 9, 1958], No. 32290/58. Class 38 (1). A socket connector for a printed circuit card comprises a body portion defining a card-receiving socket cavity, and at least one contact member constituted by a length of wire shaped into a form which provides a contact portion resiliently displaceable as a whole within the cavity and defines in said portion a plurality of resiliently interconnected contact sections by which to compliantly and tangentially engage a contact surface of an inserted printed card, the resilience being afforded by inherent resilience of the wire. In Fig. 1 a coil-spring 4 has a contact-portion 4<SP>1</SP> within a cavity 2 and a plurality of contact points are thus provided on the portion 41 for engagement with a printed circuit card inserted between the portion   4<SP>1</SP> and the lowest side of the cavity 2; barrier portions bare provided in the body 1. In Fig. 2 the resiliency of a wire 3<SP>2</SP> as a whole is afforded by the bent form of the wire in leaving the cavity 2 by way of passage 5<SP>2</SP>. An additional loop 10, Fig. 3, enhances the resilience of the contact portion 9. The contact wire 34 shown in Fig. 4 has a zig-zag contact portion 12 which, when the card is inserted, extends further into the cavity 2. If the inclination of the zig-zag contact portion is too acute, the card may become difficult to extract but this may be desirable for some applications. Alternatively, Fig. 5 (not shown), means may be provided for extending the contact portion and releasing its grip on the card. In further examples, Figs. 7, 8 (not shown), contacts engage the card on both sides at one or more contact points on each side.

Filed: 1919-12-30
Abstract: 160,925. Prestiss, A. M. Dec. 30, 1919. Spray carburettors. -Means are provided for automatically maintaining a pressure greater than atmospheric uron the surface of the fuel in the float chamber, the pressure being gradually diminished as the speed of the engine increases. In the form shown, the mixing-chamber 1 is surrounded by a float-chamber 4 to which fuel is supplied by a pump (not shown) through a pipe 57 controlled by a needle valve 56 connected to the float 55. The mixing-chamber 1 is constituted by a tube 15 carrying fuel-nozzles 49, Fig. 3, and extending upwardly to a mixture-outlet valve box 16 and downwardly to an air-inlet va.lve box 22. The rotation of the combined members 16, 15, 22 effected through a handle 29 causes the rectangular ports 25 to register more or less with mixture outlet apertures 24, the fuel-nozzles 49 to register successively with fuel-ports a, b, c, d, Fig. 3, and the elliptical air-inlet ports 28 to register in part with corresponding ports in a non- rotatable but vertically-sliding piston member 26. The fuel leaving the nozzles 49 is atomized by air supplied by a pump (not shown) to a tube 47 round each nozzle by way of passages 54, 52. Situated over the surface of the fuel in the float chamber is a piston 31 connected by links 37, 36 to the rod 35 of the vertically-sliding member 26, the piston exerting its maximum pressure on the fuel at low speeds. As the speed is increased by opening the throttle, the pressure exerted by the piston on the fuel is gradually diminished to keep the ratio of petrol to air constant. In order to control the degree of vacuum in the chamber 1, the areas of the mixture outlet ports and the airinlet ports are so arranged that when starting there is a big excess of outlet area, thus causing the member 26 to rise and depress the piston 31. On further opening of the throttle, the inlet area progressively increases in relation to the outlet area, and the member 26 tends to fall to relieve gradually the pressure on the surface of the fuel in the float chamber.
