Title: Localiser beacon system
IPC: G01S1/02
Filed: 1948-08-20
Abstract: 700,601. Radio navigation. STANDARD TELEPHONES & CABLES, Ltd. Aug. 20, 1948 [Feb. 6, 1948], No. 21981/48. Class 40 (7) A radio beacon for the azimuthal guidance of a craft along a given course comprises two antennae mounted on opposite sides of said course on a line normal thereto, a source of carrier frequency energy having two outputs feeding respective ones of said antennae, a source of sub-carrier frequency energy also having two outputs, the antennae spacing being a multiple of the carrier frequency wavelength and a fraction of the sub-carrier frequency wavelength. Means are provided for modulating each of the subcarrier outputs by both of two different L.F. signals in predetermined phase and to apply both of these modulated outputs to modulate each of the carrier frequency outputs. The modulation signal phases are so chosen that the demodulated carrier signal received at a distant point corresponds to the signal which would be received at that point from two intersecting patterns radiated from the antennae at sub-carrier frequency and modulated by respective ones of said L.F. signals. The use of a carrier enables efficient aerial systems of convenient size to be used on aircraft using the beacon and the frequency of one of the carrier frequency outputs is arranged to differ slightly from that of the other to prevent difficulties due to carrier standing wave patterns. In one embodiment carrier energy is obtained from oscillator 6 and fed through two series of frequency multipliers 7-9, 10-12 to the spaced aerial systems. A rotating condenser arrangement 15 is associated with a multiplier in one of the chains to slightly alter the frequency of one of the radiated channels. Oscillators 16 and 17 feed L.F. signals to mixer amplifier 18 from the output of which sum and difference signals f 1  and f 2  are selected by filters 19 and 20. f 1  and f 2  inputs are fed to bridge 21 from which signals of f, and f 2  are fed through amplifier 22 to modulate sub-carrier amplifier 24 and signals of f 1  and -f 2  through amplifier 23 to sideband generator 25. Units 24 and 25 are fed with sub-carrier frequency signals from oscillator 26 and their outputs are arranged to differ in phase by 90 degrees, each being fed to opposite points on bridge 28 in one arm of which there is reversal. The outputs of bridge 28 are applied to modulate the radiated carriers. A detector and phase comparator 27 is provided for monitoring and the aerial systems may be #/2 apart.

Title: A circuit system of a signal-receiver for voice-frequency dialling
IPC: H04Q1/45
Filed: 1959-06-26
Abstract: 881,779. Voice-frequency signalling. TESLA, NARODNI PODNIK. June 26, 1959 [July 9, 1958], No. 22005/59. Class 40 (4). In a V.F. receiver having a circuit Z1, Fig. 1, tuned to receive the signal frequency and a blocking circuit Z2 tuned to reject that frequency, the latter is brought into circuit by the energization of a slow-release relay F which is dependent on the receiving relay P. A twofrequency receiver is also described, Fig. 2 (not shown). As applied to working between two exchanges A, B, Fig. 3, relays F at both ends of the junction are de-energized normally and also while a call is being set up, so that the blocking circuits Z2 are ineffective. When the called party at exchange B replies, a relay H (not shown) responds and sends a signal to connect up a similar relay at exchange A. Relays F energize at both exchanges so that the V.F. receivers are now protected against operation by speech which is unlikely to contain a pure signalling frequency of sufficient duration to release relay F.

Abstract: 1474335 Counting apparatus SPERRY RAND CORP 22 May 1975 [4 June 1974] 22077/75 Heading G4D  The invention relates to apparatus for comparing and indicating when two compasses are out of step. The gyrocompasses are arranged to produce a three phase signal (Fig. 1, not shown), each phase comprising a burst of high frequency lasting for one half degree of rotation and nothing for the next half degree. At 15, 17 the resulting modulated pulse trains are converted to UP and DOWN pulses according to the direction of rotation, the same direction of rotation producing UP pulses from one compass and DOWN pulses from the other. The individual UP and DOWN pulses are held in stores 27-33 which are interrogated repeatedly by a four phase clock 35 and the released pulses are counted up and down by a counter 37. A circuit 41 reverses the counting direction when the count passes through zero so the count is always positive. An alarm is sounded or lit when the count exceeds a value set at 45 for more than a delay period set at 53.
