Abstract: 967,164. Hydraulic apparatus. COAL INDUSTRY (PATENTS) Ltd. Oct. 12, 1960 [Oct. 12, 1959; June 16, 1960], Nos. 34500/59 and 21211/60. Heading F1P. In an advancing mine roof support system comprising a series of hydraulic prop units each provided with a double-acting ram connected to a conveyer, means are provided to jointly operate the rams for advancing the conveyer and then advance each prop unit in turn when the adjacent unit is in the support position. The props 2, 3, are fed with pressure fluid from a circuit including a conduit 17, a check valve 21, a control valve 22 and a relief valve 24. The ram 5 is controlled by a valve 25 and energized through a pressure line 19 to advance the conveyer. To advance the props pilot pressure is fed through a conduit 20 to spaces 29, 31 in the valves 22, 25 to displace their plungers and connect the props and the underside 27 of the ram 5 with the exhaust line 18, the other side 33 of the ram being connected to the pressure line 17 to advance the props. As the ram reaches its limiting position it moves the plunger 36 of a valve 16 to connect the pressure line 20 with the underside of the valve 22 and thereby re-connect the props with the pressure line 17. A valve 40 subjected to the pressure within the props is incorporated in the circuit as shown to reset the valve 25, the prop pressure being also transmitted through a conduit 45 to a second prop unitsaid conduit 45 corresponding to the conduit 20 of the present unit. In a modification, the plunger of the ram 5 is adapted to operate a limit switch connected in series with a pressure switch operable when the props are fully set to initiate operation of the next support for details of the hydraulic and electrical circuits, Figs. 4-7 of the Complete Specification (not shown) should be referred to. In a modification, see Fig. 1 of Provisional Specification 21211/60 (not shown), the unit includes solenoid operated valves having additional manual control means, the control arrangement consisting of an hydraulic leg control valve, an hydraulic ram control valve, an hydraulic leg relief valve and a non- return valve for details of which the Specification and Application 18862/60 should be referred to, further modifications being disclosed with reference to Figs. 2 and 3 of said Provisional Specification.

Title: Improvements in or relating to heterodyne receiving systems
IPC: H03D1/16
Filed: 1930-11-20
Abstract: 359,760. Valve circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.-(Assignees of Roberts, W. van B. ; 155, Hodge Road, Prineeton, New Jersey, U.S.A.) Nov. 20, 1930, No. 34992. Convention date, Nov. 20, 1929. [Classes 40 (iii) and 40 (v).] A superheterodyne receiving system comprises a low-pass filter passing only frequencies below the upper limit of a desired frequency range, an intermediate frequency amplifier tuned to a frequency above that upper limit, and a pair of frequency changing valves so disposed that beat currents due to interacting signal frequencies are balanced out, while those due to the heterodyne are additive. The input from the aerial 3 is passed through a low-pass filter 1, 2, having terminal resistances R1, R2, and thence over a grid leak R3, condenser C, antiparasitic resistance K to the mid-point of inductance 6. From the tuned e.rcuit 6, C1, the signal is impressed in phase opposition on the grids of a push-pull pair 8, 8<1> which constitute the local oscillator of the receiver, and which are kept in balance by a slider P. The output from the oscillator comprises a tank circuit I differentiary connected in the anode circuits. The cutput from this circuit is transferred to inductance 18 8 forming the input to the intermediate frequency amplifier J (not shown). When the oscillator 8, 8<1> is inoperative all currents in the anode circuits due to incoming signals cancel out in circuit I; when the oscillator is functioning such components of anode currents as depend on the phase of the oscillator voltage will accumulate in I, resulting in production of beats between oscillator and desired signal, while no beat is produced between incoming signal frequencies.

Abstract: 1,253,903. Sensing rest or motion. STANDARD TELEPHONES & CABLES Ltd. July 11, 1969, No. 35064/69. Heading G1K. A movement sensor for use with rotating equipment which equipment includes a rotating disc D subject to eddy current braking control from fixed permanent magnets M, M<SP>1</SP>, wherein the eddy currents generated in the disc D at the start of its rotation act electromagnetically upon a sensing element P from which action a signal voltage related to the movement of the disc D is derived. The sensing element P may be a high permeability magnetic core C of C-form embracing a portion of the disc D in the vicinity of an eddy current path L established between a pair of permanent magnets M, M<SP>1</SP> of reversed polarity with respect to one another so that the eddy current is due to them acting together. A coil coupled inductively with the core C generates the signal voltage. Alternatively, Fig. 2, the eddy currents generated in disc D act on a C-form permanent magnet A embracing the disc and mounted between pivots B, B<SP>1</SP> with an axis of rotation normal to the plane of the disc, the magnet carrying a shutter vane V which controls the illumination path of a photo-electric device which initiates the signal voltage. The magnet may be controlled by a restoring spring S together with a zeroadjusting device or by gravity mechanism. The movement sensor may be used in the bearing resolver of Specification 991,365, the signal voltage being processed to establish a voltage at a predetermined level for a predetermined time which is applied as a "blocking voltage" to suppress a display when the resolver is taking up a new position corresponding to a signal which starts before the previous one has ceased.
