Abstract: 948,451. Pulse radar. ALBISWERK ZURICH A.G. May 19, 1960 [May 22, 1959], No. 17694/60. Heading H4D. In a pulse radar in which the timing of a strobe pulse is progressively varied until it encounters an echo pulse, means are then automatically actuated for causing the strobe pulse to track the echo pulse automatically only if the duration of the echo pulse encountered is less than a predetermined value. As described, the strobe pulse comprises a pair of contiguous early and late gate pulses 11b 11a Figs. 2a and 2b, which are applied together with the echo pulses to a discriminator, Fig. 4, which produces during any one pulse recurrence period a positive sample pulse if only the late gate pulse 1 la is coincident with the echo pulse and a negative sample pulse if only the early gate 11b is coincident with the echo pulse. The sample pulses are integrated at the output of the discriminator so that as the gate pulses sweep through the echo pulse during successive recurrence periods a positive output signal 12 is produced continuously during those recurrence periods in which the overlap between the late gate pulse 11a and the echo exceeds the overlay between the early gate pulse 11b and the echo and a negative output signal 13 is produced continuously during those subsequent recurrence periods in which the overlap between the early gate pulse 11b and the echo exceeds the overlap between the late gate pulse 11a and the echo. In Figs. 2a and 2b, the time scale, which is in the direction of the arrow from right to left, corresponds to the strobe sweep time base, i.e. the time variation of the gate pulses, and the equivalent duration of an echo on such a time scale is shown by the pulse 10. The output from the discriminator is applied (1) via a rectifier 55, Fig. 5, to a mono-stable multivibrator 50 which is triggered only by a positive output signal 12 to produce a pulse 14 whose duration as measured on the strobe sweep timebase is equivalent to the predetermined echo pulse duration, the pulse 14 being applied to one grid of a gas discharge coincidence valve 51 and (2) to a normally conductive valve 53 which selects a negative output signal 13, inverts it and applies the resultant positive signal to the other grid of the coincidence valve 51 which fires to actuate a relay 52 and so initiate the automatic tracking only when the signal 13 coincides with the pulse 14. Discriminator, Fig. 4. The positive early and late gate pulses 11b, 11a are applied respectively via terminals 41 and 42 to the grids of a double triode 40 and the negative echo pulses are applied to the common cathode via a terminal 44, the anode outputs being transformer coupled through oppositely poled rectifiers to the R.C. integrating circuit 49, 49a which is connected between earth and the output terminal 48. The early gate pulse is produced by a blocking oscillator, Fig. 3 (not shown), and the late gate pulse is produced by applying the early gate pulse to a delay line.

Filed: 1973-04-13
Abstract: 1448871 Television distribution systems BRITISH RELAY Ltd 11 July 1974 [13 April 1973] 18038/73 Heading H4R Multiprogramme TV signals are distributed over a single cable pair or coaxial cable as suppressed carrier luminance and, if colour, suppressed carrier chrominance modulations accompanied by a pilot, the suppressed carrier frequencies being different multiples of the pilot frequency or offset from such multiples by multiples or submultiples of the frame and/or line frequency. The lowest band programme may be transmitted in known manner as the upper sideband of a 4À43 MHz carrier and two upper band programmes on carriers of 14À35 and 24À60 MHz which are 7th and 14th harmonics of a 2À05 MHz pilot. Another cable pair may use a synchronized 4À43 MHz carrier for the lower band or the 5th harmonic of the same 2À05 MHz pilot; upper band carriers being 10th and 15th harmonics. The pilots in different pairs may be offset and need not accompany the corresponding modulation carriers. This requires a phase locked loop at the receiver which could serve to synchronize the transmitter and receiver if the pilot phase or frequency is periodically altered or switched between pairs for scrambling purposes in a subscription system. The suppressed carriers are regulated at the receivers from the pilot and if necessary the frame and line information in the programmes.

Abstract: 1387316 Touch switches LICENTIA PATENT-VERWALTUNGS-GmbH 19 April 1972 [21 April 1971] 18089/72 Heading GIN [Also in Division H3]  In a tuning circuit having a uni-directionally conductive device, such as a switching diode 6, 7 Fig. 1 coupling a source of tuning voltage 1, 2 to a voltage controlled reactance, such as a capacity diode 3, when a switchable means 8, 9 is conducting it substantially short circuits the source of tuning voltage and blocks the uni-directionally conductive device 6, 7 and in response to actuation of a contact switch, including two fixed contacts which are bridged when touched by the resistance of the finger of an operator, the switchable means 8, 9 is blocked and the tuning voltage is applied to the reactance 3. By touching a contact 13 a holding circuit 11 is operated to block transistor 9 so that the tuning voltage set by a potentiometer 1 is conducted via a diode 7 to the tuned circuit 3. Due to a quenching connection 14 the transistor 8 is made conductive so as to reverse bias the diode 6 and prevent the tuning voltage set by the potentiometer 2 from being applied to the tuned circuit 3. The tuning voltage set by 2 is similarly obtained by touching contact 12. The holding circuit 11 may consist of transistors 26, 27, Fig. 2 which turn on when their associated contact 13 is touched. This blocks the transistor 9 and connects the tuning voltage from 1 via diode 7 to tuned circuit 3 as described above. Also a pre-selected frequency band is connected via a diode 36. The quenching connection 14 is connected to the emitter of transistor 26 so as to render it off when another one of the blocking circuits is selected since the voltage at the common resistor 33 is increased. A capacitor 35 and resistor 34 are connected so that when a receiver, in which the tuning arrangement is used, is switched on the associated circuit part 16 is switched on. Additional contact switches can be connected in parallel with the contact switches 13 for remote control.

Abstract: 916,690. Coin-freed telephones. TELEFONAKTIEBOLAGET L. M. ERICSSON. May 28, 1959 [May 29, 1958], No. 18226/59. Class 27. [Also in Group XXXIX] In a telephone substation wherein voicefrequency digital signals are transmitted to the exchange by connecting impedances into an oscillator circuit, a coin-box includes coinactuated contacts which each connect a corresponding impedance into the oscillator circuit to transmit a v.f. tone indicative of the value of the coin concerned, and means is provided which, prior to being actuated by v.f. signals from the exchange, prevents the sending of the coin-value signals. The arrangement shown includes a telephone set of the type described in Specification 790,442, [Group XXXIX], in which depression of button AS (Fig. 1) connects up the v.f. generator S 1  and upon reception of " ready tone " from the exchange (Fig. 2) the closure of selected keys P1-P3 completes the oscillator circuit to transmit the relevant v.f. tones to the exchange to control the extension of a connection to the wanted station B (Fig. 1). Removal of the hand set operates cradle contacts K. The speech connection is not completed until one or more coins sufficient to pay for one conversation period have been inserted in the coin-box. To this end the translator OR responds to the wanted number to operate one or more of the relays R I , R II , R III , corresponding to the unit cost concerned. On the reply of the called party the feed relay R5 is replaced by R2 to which the operation of R4 connects the v.f. tone fa. This tone is passed by filter Qa to operate MO which reconnects the generator S to the line. The tone f1 (also connected up by R4) now passes through filter QA to operate TMA which energizes the coin progressing magnet M1 thus moving the coil slide KL1 to the right. This allows a 1 crown coin (if present in the shoot) to close coin contacts MK1 and effect transmission of the v.f. tone proper to that coin value. Assuming the cost of the call to be 1 crown, OR will have operated R 1  and if a 1 crown coin has been inserted, MK1 will be closed and RA1 responds to the tone. The operation of RA2, which follows, completes a circuit in the comparator KO to bring up R8, indicating that the unit cost of the call has been paid. R3 is released and the conversation connection is restored. The consequent connection of tone fb to the line operates MU via filter Qb, whereupon MO and MU release. The disconnection of tone f1 releases M1 and the 1 crown coin drops into a container (not shown) ; the coin tone ceases, RA1 releases, R1 operates and tone fb is disconnected. For the control of the other coin shoots (50 ore and 25 ore) tones f2 and f3 are sent from the exchange, operation being similar in each case. Cam KI effects release at the end of the time paid for, cam KII having connected up a warning buzzer prior to this.
