Title: Tape magazine for automatic telephone dialer
Inventor: KILBURG JAMES
IPC: G11B15/68
Filed: 1962-07-26
Abstract: 949,534. Magnetic tape cassettes; telephone dialers. DIALPHONE. July 26,1962, No. 28722/62. Heading G5R. An interchangeable cassette 11 carries a sprocketed tape whose magnetic-coating side is transduced by a transversely-moving head 14 while a related part of its other side, containing written or printed information relative to the corresponding magnetic track is guided by roller and table means 40-43 to present the information visually at a window of the apparatus (Fig. 1, not shown). Where the line of magnetically recorded information provides the dialling pulses necessary to obtain a telephone connection, the name &c. of the number called may be written or typed on to the tape which may be raised 41a for insertion of a typewriter platen against the action of returnspring means in the drums 34, 35. To obviate dropouts, the drive sprocket 44 has recesses 75 allowing effective transducing contact of the head 14, despite indentation of the tape due to writing or typing. The cassette is loaded into the apparatus by stud-and-keyhold means (Fig. 3, not shown) and the loading engages the sprocket 44 with detent means (Fig. 4 not shown), which halts the tape in alignment with a selected track. Track-selection is by unspecified electric drive means to the sprocket 44 controlled by forward and reverse push-buttons and a hand wheel, whose access through the cover of the apparatus, permits incremental movement of the tape, one track at a time.

Title: Improvements in or relating to wave filters and systems utilising wave filters
IPC: H03H11/04
Filed: 1936-10-23
Abstract: 483,668. Current meters. STANDARD TELEPHONES & CABLES, Ltd., and BARNARD, R. M. Oct. 23, 1936, No. 28864. [Class 37] [Also in Group XL] A filter F having a narrow pass band and adjustable frequency is used for analyzingwave form. The strength of each harmonic produced by an amplifier AMT under test, when it operates on a standard tone derived from an oscillator OSC1, purified by a harmonic-suppressor HS, and adjusted to standard amplitude by means of an attenuator AT2 and valve voltmeter VV2, is measured by comparison with the fundamental. Terminals 1 and S are connected so that the output from the amplifier AMT reaches the valve voltmeter VV4. The fundamental is first measured, and for this purpose the fundamental-suppressor FS is disabled while the filter F is tuned to the fundamental. The attenuator AT3 is adjusted to give a standard reading on the valve voltmeter VV4. The procedure is next repeated for each harmonic, the filter F being tuned thereto while the fundamental is suppressed at FS to prevent overloading of the filter. The settings of the attenuator AT3 enable the amplitudes to be compared. The filter circuit is calibrated by connecting terminals to terminals Z, adjusting oscillator OSC2 to the harmonic frequency and to the standard level of 1À2 volts, and setting the attenuator AT4 till a standard deflection is obtained on the valve voltmeter VV4. The percentage of harmonic under test is deduced from the three readings obtained from attenuators AT3, AT4.

Title: Improvements relating to hydraulic power transmissions for vehicles
IPC: F16H61/46
Filed: 1954-10-13
Abstract: 762,721. Turning-gear. DAIMLER-BENZ AKT.-GES. Oct. 13, 1954 [Oct. 13, 1953], No. 29565/54. Class 7 (5). [Also in Group XXIX] A hydraulic power transmission for a vehicle comprises a hydrostatic pump and motor, and the pump is adapted to serve as a starter for the vehicle engine and also supplies pressure liquid for actuating servo devices. The transmission comprises a pump Gp driven by a vehicle engine shaft A and a motor Gm driving a shaft B. Servo devices S are connected to a pressure pipe 33 connecting the output of the pump to the motor. For starting the vehicle engine, with a valve U in the position shown, a pump P1 driven by an electric motor E supplies liquid through pipes 39, 40 to the input side of the pump Gp which is consequently driven as a motor. Liquid is also supplied through a pipe 44 to the servo devices S. An accumulator Q is either charged by the pump P1 or assists that pump in supplying the pump Gp and devices S, according to whether it is charged or not. If the valve U is rotated anti-clockwise through 90 degrees by moving a lever 50 from a contact 55 to a contact 56, the engine is started by the accumulator Q supplying the pump Gp. Rotation of the valve U through a further 90 degrees by moving the lever 50 to a contact 57 enables the pump P1 to charge the accumulator and supply the servo devices with the pump Gp, and the vehicle engine, stationary. For normal running the valve U is rotated through a further 90 degrees by moving the lever 50 to a contact 58, in which position pipes 30, 31, 40 are interconnected and the pump Gp drives the motor Gm. The rotation of the output shaft B acts through a centrifugal governor F to open a contact 64 and switch off the electric motor E. An auxiliary pump P2 driven from the shaft B keeps the input side of the pump Gp under slight pressure. A regulator R controls the pressure in the pipe 40, and as lever 50 is moved from contact 55, 56, 57 to 58 the regulator R is progressively adjusted to reduce the pressure in pipe 40.

Abstract: 1317661 Gas discharge tube dimmer PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 19 June 1970 [24 June 1969] 29879/70 Heading H2H In a circuit arrangement for the stepwise dimming of parallel connected discharge lamps, each discharge lamp has at least two ballast impedances connected with it, and at least one bridge rectifier associated with one of the ballast impedances. The heater electrodes of low pressure mercury discharge lamp 13, are fed from transformer 10 via secondary windings 11 and 15. The electrode 14 is connected to ballast inductors 16, 18 and 20. Ballast inductors 18 and 20 are connected to bridge rectifiers 17 and 19. Similar connections are made to a second discharge lamp 13<SP>1</SP>. Currents can only flow across the bridge rectifiers 17 and 19, and 17<SP>1</SP> and 19<SP>1</SP> when the appropriate switch 21 or 22 is closed, these switches being effectively connected across the rectifier bridges. In this way the discharge lamp 13 and 13<SP>1</SP> can be dimmed in a stepwise manner. The rectifier bridges having the effect that the two discharge lamps circuits are effectively decoupled so that the failure of one lamp does not affect the other. In a second embodiment the ballast inductors may be all connected in series and the rectifier bridges may be used to short out appropriate ballast inductors.

In modifications the input circuit of the regulator 7 may be energized in accordance with the voltage drop across the furnace, or current control together with a voltage control 1a, 2a may be provided. When regulation by voltage only is required, the A.C. winding of the reactor may be connected across the furnace in series with a potentiometer or transformer. Overriding control may be effected by the potentiometer 13 from a control station common to a plurality of similar furnaces and in accordance with the response of a maximum demand limiting device. Individual adjustment of the regulators of the several furnaces may also be superposed on the common control. The installation may include in addition to one or more arc furnaces, one or more H.F. furnaces, the output of which may be adjusted by reactors controlled by the potentiometer 13.
