Title: Improvements in or relating to phase comparison radio navigation systems
Inventor: ROBERTS GRAHAM ESTYN
IPC: G01S1/30
Filed: 1964-07-31
Abstract: 1,086,733. Radio navigation. DECCA Ltd. July 16, 1965 [July 31, 1964], No. 30353/64. Heading H4D. The invention relates to a receiver in a hyperbolic navigation system of the type disclosed in Specifications 765,573 and 949,480, wherein each station in turn produces a multi-frequency transmission during periodic interruption in the normal transmissions said receiver using only one received frequency, and comprising a tuned receiver stage 11, tuned in this embodiment to the frequency normally produced by the master station. The receiver also comprises a phasecontrolled oscillator 14 operating at said frequency and feeding its output to one input of a phase discriminator 13 having the output of the receiver stage 11 applied to its other input. During the normal transmissions, the signal from the master station is thus compared in phase with the output of the oscillator, and a signal equal to the sine of the phase difference is used to control the phase of the oscillator via closed relay contact 17, such that the oscillator output is phase locked to the normal master station transmission. Break detector 18 detects the break in transmission of a specific length occurring at the end of the normal transmission period, and the beginning of the multi-frequency transmission period, and actuates a relay, such that contact 17 opens, and contacts 21 and 22 close. The signal in the multifrequency transmission at said frequency is received in stage 11 and compared in phase with the output of oscillator 14, still locked to the master station normal transmission. The sine output of the phase discriminator together with a cosine output is fed via contacts 21 and 22 to a selector switch 24. The selector switch is controlled by a connector 28 which in turn is controlled by the break detector 18, such that the two outputs are fed to the one of three phase difference indicators allocated to the slave station giving the multi-frequency transmission. There are thus provided three differential phase indications based on three confocal hyperbolic isophase systems having foci at the master station and at the respective slave station and having lane widths corresponding to the normal frequency of the master station. To overcome phase ambiguities, each phase difference indicator may comprise a cycle integration counter or form part of an automatic chart position indicator.

Title: Improvements in or relating to automatic or semiautomatic telephone systems and apparatus for use therewith
IPC: H04Q3/00
Filed: 1923-12-03
Abstract: 229,779. Automatic Telephone Manufacturing Co., Ltd., and Ostline, J. E. Dec. 3, 1923. Automatic exchange systems; metering.-In a line switch of the kind which is restored to a normal position after use, an outgoing line is accessible from this position on an outgoing call, but is cut off on an incoming call, preferably by the use of a mechanical interlock between the line and cut-off relays. When the calling subscriber removes his receiver, the line relay 4 earths the private wire 3, closes a series circuit for the cutoff relay 7 and stepping magnet 8, and connects a point between them to the test wiper 16. If the trunk connected to the normal position is busy, the wipers are stepped on in known manner, but if it is free, the cut-off relay 7 operates, switches through the calling line, and at armature 11 prepares a circuit for the meter magnet 24<1>. The connection is set up in the usual manner, and when the called party replies, earth is sent back over the fourth wiper 19 to energize the meter magnet 24' in series with the stepping magnet 8. The meter magnet 24<1> locks up over its armature 25<1> to prevent further accidental operation. When the calling subscriber hangs up, the removal of earth from the test wire 26 de-energizes the cut-off relay 7, which at armature 11 opens the metering circuit and closes a restoring circuit for the stepping magnet 8 over the off-normal springs 14 and armature 5. The wipers are thus stepped round until a cam 15 on the wiper shaft opens the springs 14 when the switch has reached normal position. The mechanical interlock between the relays 4 and 7, whereby when the cut-off relay 7 is energized and the line relay 4 is inert, the armatures 10. 13 leave their back contacts but do not engage their front contacts so as to disconnect the wipers in the case of an incoming call, is well known. If it is desired that a movement of the wipers should take place every time the switch is taken into use, the trunk line leading from the normal position is made last choice instead of first choice by arranging for busy potential to be connected to the test contact in the normal position over the back contact of a. relay which is only energized when all the other lines are in use.
