Filed: 1944-08-01
Abstract: 584,457. Multiplex signalling. STANDARD TELEPHONES & CABLES, Ltd. Aug. 1, 1944, No. 14674. Convention date, Sept. 29, 1943. [Class 40 (v)] In a multiplex time-modulation pulse signalling system, in which a plurality of time modulated trains of signal impulses are combined in time displaced relation, the receivers are synchronised by means of impulses derived from a resonant circuit tuned to the mean combined pulse repetition frequency of the composite signal train. One of the trains of impulses may be utilised as a monitor channel, means being provided at the receiver station to observe the monitoring interval and align the receivers with their proper channels. The pulse transmitters 1, 2, 3, for the signal channels 21, &c., are operated in sequence by means of impulses derived from the source 10 over phaseshifters 11, &c. The additional transmitter M derives a monitoring signal from the source 24 and is operated in sequence with the transmitters 1, &c., over the additional phaseshifter 13. The combined impulses are applied to the line 70, and at the receiving station are applied to the receivers 31 &c., and 3M and the synchronising source 29. The synchroniser 29 may comprise a circuit 27 tuned to the mean combined pulse petition frequency, or may be an oscillator held in synchronism by the pulses. The output is applied to a frequency divider 25, producing impulses which are applied over the adjustable phase-shifter 26 and individual phase-shifters 34, &c., to operate in proper sequence the receivers 31 &c., and 3M, correct channel alignment being achieved by adjustment of the phase-shifter 34 until the monitoring signal is received in the channel 3M. The receivers 31, &c., may be of the type described in Specification 600,291. In an arrangement of this type the demodulating wave may be derived from a frequency converter 125 operating from the synchroniser 29, and may be applied to the receivers 31, &c., over an adjustable phaseshifter 130 and the individual phase-shifters 131, &c. Return channel. The pulse transmitters 41, &c., for the return channels 51, &c., derive operating impulses from the frequency divider 25, over phase-shifters . 44, &c., the return monitoring channel comprising the transmitter 4M and monitoring source 54. The receivers 61 &c. and the monitoring receiver 6M, are synchronised from the source 10 over the adjustable phase-shifter 67 and individual phase-shifters 64, &c. They derive demodulating waves from the frequency multiplier 150 controlled by the source 10, over adjustable phase-shifter 160 and individual phase-shifters 161, &c. In an alternative arrangement (Fig. 3, not shown), the transmitters 1, &c., derive energy directly from the control wave source 10, the modulated pulses of the separate channels then being suitably spaced by individual delay lines to permit of combination to a multiplex wave. Specifications 509,820 and 600,244 also are referred to.

Inventor: WATERS CHARLES BOYD
IPC: H01F38/08
Filed: 1918-09-13
Abstract: 125,873. Waters, C. B. July 2, 1918, [Convention date]. Transformers.-A transformer for supplying a welding or cutting are has its secondary in the form of three windings 16, 17, 18 in series and wound on separate legs of a core having no air gaps. The leg 13 is of less cross-section than and forms a shunt to the other two legs, the winding thereon acting as a baiance winding. At light loads the core 13 shunts a large proportion of the flux produced by the primary 14, but as the secondary current rises, the opposing magneto motive force produced by the current in coil 17 causes a reduction in this shunt effect. A still further increase results in a reversal of potential in the coil 17. This action tends to keep the E.M.F. in the secondary constant. Taps on the coil 18 allow the output to be adjusted to the load; or a movable core may be used for this purpose. By having duplicate sets of secondary windings on the same or different legs, two arcs may be supplied.

Abstract: 815,815. Projectile fuzes. ERINRO Ltd. May 14, 1956 [June 1, 1955], No. 15006/56. Class. 9(1) An electric projectile fuze comprises a condenser charged during firing of the projectile and adapted to be connected during flight to the internal firing circuits by an inertia switch, which switch includes a piston movable in a cylinder containing a damping liquid of substantially constant viscosity over a given temperature range. The switch IIC comprises a metal cylinder 3 electrically connected to the condenser and housing a piston 4 held by a spring 5 against an insulated contact 6 connected to the charging lead 1. The cylinder contains a liquid, e.g. silicone oil, which slows down the movement of the piston to its final position in which a pin 9 touches a contact 10 to complete the circuit through the primer (not shown) and so arm the fuze. The arming time depends on the loading of the spring-adjusted by screw contact 6-the viscosity of the fluid, the mass of the piston, &c. The fuze incorporating the switch may be as described in Specifications 815.816 and 815,817.

IPC: G01S1/02
Filed: 1954-05-24
Abstract: 780,738. Pulse length measurement. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 10, 1955 [May 24, 1954], No. 15252/54. Class 37. Apparatus indicating pulse length of a periodic rectangular pulse waveform comprises means producing a first voltage representing the peak voltage thereof referred to a datum and reduced to half the peak value, means for producing a second voltage representing the average value of the waveform voltage referred to the datum, and means responsive to the amplitude and sense difference of the voltages to indicate the pulse length. A double triode 1 of a known " flip-flop " circuit (not shown) responsive to time-displaced peak pulses derived e.g. from phase comparison of the squared and limited audio outputs of a radio navigation system, produces at the anode of its second section a train of rectangular pulses (Fig. 2a, not shown) of repetition period t and varying width w responsive to the time displacement of the input peaks, which is capacitance coupled to the anode of a diode rectifier 5 whose cathode is positively biased to a voltage x (Fig. 2b, not shown). The resultant rectangular pulse train is directly coupled to the grid of cathode follower triode 7 to produce a positively and negatively limited rectangular pulse train of amplitude slightly less than x (Fig. 2c, not shown), which is directly coupled to the anode of diode rectifier 11 whose cathode charges capacitance 13 shunted by equal series resistances 14, 15 to have time constant large compared with the repetition period t of the pulse trains, so that the voltage there across remains substantially constant at the peak value; The cathode signal of triode 7 is also connected over resistance 16 to capacitance 17 the time constant being sufficiently long that the voltage thereacross is substantially the mean value of the cathode signal voltage, and a centre zero voltmeter or other indicator 18 is connected between the junction of resistance 16 to capacitance 17 and that of resistances 14 and 15, so that the instrument reads zero for w = t/2 and is deflected in opposite directions proportionally to longer or shorter pulses. For indication of the phase differences of the audio outputs of radio navigation apparatus, the instrument may be calibrated from 0 to 360 degrees about a centre point of 180 degrees, while a resistance may be connected by normally open switch 19 between the H.T. line and the anode of diode 5 for calibration by adjustment of voltage x for full-scale deflection.
