Title: Improvements in or relating to Automatic Telephone Exchange Systems
Inventor: BROWELL LESLIE JAMES
IPC: H04Q3/42
Filed: 1965-11-18
Abstract: 1,151,731. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. 2 Nov., 1966 [18 Nov., 1965], No. 48963/65. Heading H4K. In an exchange system provided with a number of multiparty lines, a call from any one of the party line subscribers causes a relay store to be associated with the line whereby a subsequent multipotential signal which identifies the subscriber may be temporarily stored prior to its transference to the line's relay set/meter store where it is used for connecting up the relevant meter to the P-wire. The store includes a capacitive dialling-tone by-pass circuit which allows dialling tone reverted from the selectors to reach the calling subscriber. On hearing this tone, the subscriber actuates his identifying key which connects a unique rectifier /earth combination to the line wires. Four relays in the store respond to the identifying signal and when the key is released (and not before) initiate the above mentioned "data" transfer and the through-connection of dialling tone via the relay set. The store is common to a plurality of party lines and is seized by a calling line in dependence on the state of a relay contact lockout chain. Faults.-If the subscriber fails to identify himself or to dial a number, the exchange S and Z pulses cause the relay store to time-out and cause N.U. tone to be reverted to the caller. If the caller hangs up prior to identifying himself, the store times out unaided and a burst of N.U. tone is reverted. If an earth fault exists on the - ve line wire, the store is automatically seized and in turn seizes the relay set/meter store but in this ease the latter is busied and N.U. tone is reverted to the caller until the fault is cleared. If an earth fault exists on the + ve line wire, N.U. tone is reverted whenever a call is initiated and an alarm (not described in detail) is actuated.

Abstract: 1,234,997. Lasers. HUGHES AIRCRAFT CO. 31 Oct., 1968 [1 Nov., 1967], No. 51645/68. Heading H1C. An infra-red laser communication system comprises two similar transmitter-receiver laser devices tuned to slightly different frequencies, each of which may be as shown in Fig. 1, both devices generating an output beam simultaneously which is directed at the other device, with the beam of the device then transmitting being modulated by an information signal, the two beams-local and distant-at each device being combined by a beam splitter 14 and applied to a respective photo-electric detector 16 for subsequent demodulation. Beam modulation of the device then transmitting is effected by an electro-optic crystal 30 located between the laser resonator mirrors 12, 13, as shown, by a capacitor transducer having one electrode serving as a resonator mirror, Fig. 1b (not shown), or by a piezo-electro transducer controlling the resonator length, these arrangements producing frequency modulation. For amplituce modulation an electro-optic crystal is positioned outside the resonator and in the path of the incoming and outgoing beams, Fig. 1c (not shown). The output of the photoelectric detector 16 is amplified at 20 and is demodulated by an f.m. limiter discriminator 24 for frequency modulation, or by an a.m. detector (23), Fig. 1c (not shown), for amplitude modulation, the resulting demodulated signal being applied to a "signal out" terminal. In addition, automatic frequency control of the beam generated by the device is obtained by applying the demodulated signal through a low-pass filter 26 and amplifier 28 to either a piezo-electric crystal 31 controlling the axial position of mirror 12 or to the capacitor transducer, Fig. 1b (not shown). The beams may be generated by an He-Ne or CO 2  active medium 11 and are transmitted and received through a telescope 32. In a modification, Fig. 2, the resonator is formed by three mirrors 212, 213, 214, the intermediate one 214 of which is partially transmitting and serves as the beamsplitter. In a further modification, Fig. 3, the incoming and outgoing beams 40, 38 are transmitted along different parallel paths and are combined in the beam-splitter by mirrors 36, 42. A single path and a plurality of beamsplitters are used in Fig. 4, the outgoing beam 50 having a portion 60 deflected by a beamsplitter 414a and the incoming beam 54 having a portion 56 deflected by a beam-splitter 414b, the two portions being combined in a beam-splitter by a mirror 48.
