Filed: 1924-09-15
Abstract: 233,288. Siemens Bros. & Co., Ltd., and Patterson, W. G. Sept. 15, 1924. Automatic exchange systems.-In a connector of the Strowger type in which ringing current is fed over a winding of the ring cut-off relay and contacts of the test relay, the ring cut-off relay energizes in the event of the wanted line being busy and connects busy tone to the calling line. The circuit of line relay A includes a contact m1 controlled by the release magnet MM, and im. pulses are repeated at back contact a1. The same sluggish relay C is included in series with the vertical and rotary magnets VM, RM and controls sluggish change-over relay G. Relays C, G fall back in turn at the end of impulsing, connecting test relay H to the test wiper momentarily over contacts c2, g1. Relay H energizes if the wanted line is free, and short-circuits high resistance winding 1 to mark the line engaged. Ringing current is sent over relay F and contact g3 when relay G fall back, and ring cut-off relay F energizes upon reply of the called party and completes the connection. Relay D energizes and reverses the current over the incoming talking wires for metering or coin collecting. If the wanted line is busy, relay H fails to operate, and is disconnected at contact g<1> when relay G relapses. Relay F then energizes over winding 2 and connects up busy tone at contact f5. The opening of contact m1 when the release magnet MM operates serves to prevent seizure of the connector after contact b1 is opened.

Title: Radio beacon system
IPC: G01S19/11
Filed: 1946-03-08
Abstract: 609,191. Radio navigation. STANDARD TELEPHONES & CABLES, Ltd. March 8, 1946, No. 7318..Convention date, March 10, 1945. [Class 40 (vii)] A directive radio beacon for defining a fixed course comprises means to develop in space a field pattern having off-course lobes of sideband energy with substantially suppressed carrier and an on-course pattern including a carrier component, means to reverse the phasing of said side-band lobes and means to modulate the energy in said lobes at different low frequencies in timed relation with the phase reversal so as to define in combination a desired course; the last-named means comprising a single modulator upon which both the lowfrequency modulating voltages are impressed. In the embodiment described, which is stated to be an improvement on systems of the type described in Specification 563,007, the output from the radio frequency oscillator 7 is fed to two amplifiers 9 and 10 and thence in phase to diagonally opposite points of the bridge 8. Amplifier 10 also operates as the audio frequency modulator. The output from the top corner of the bridge (as shown) is fed to tuned dipole 1 and consists of both carrier and sidebands. The output from the remaining bridge corner, consisting of side-band energy only, is fed through switching relay 13 to tuned dipoles 2 and 3 in phase opposition. Relay 13 serves to reverse the phase of the applied energy and its operation results in the successive generation of corresponding overlapping field pattern lobes defining the course. Relay 13 is synchronized with the movement of contact arm 15 feeding either a 90 c/s. or a 150 c/s. audio-frequency signal from source 18 or 19 to modulator 10; thus each lobe of the overlapping patterns is characterised by its own audio-frequency modulation. At the craft, the signals are received and detected and the 90 c/s. and 150 c/s. signals separated and applied to one movement of a cross-pointer meter which is shunted by a condenser to maintain the indication steady. A-N or similar keying of the beam may be used in conjunction with an aural signal device on the craft.

Filed: 1946-03-08
Abstract: 609,195. Valve generating circuits. STANDARD TELEPHONES & CABLES, Ltd. March 8, 1946, No. 7325. Convention date, March 2, 1944. [Class 40 (vi)] An electric oscillation generator comprises a fixed frequency oscillator, the output of which is modulated by a variable frequency oscillator, means to select the upper side-band frequency and for applying this to synchronize a multivibrator, and means to select a specified harmonic frequency of the wave generated by the multi-vibrator. In the Figure, the output from a fixed frequency (F) oscillator A which may be of the crystal-controlled type is applied to modulator C, together with the output from a variable frequency (f) oscillator B. The upper side-band F+f is selected by high-pass filter D and applied to synchronize multivibrator E. The natural frequency of the multi-vibrator is a sub-multiple of the applied F+f frequency and is equal to ---. The output m from multi-vibrator E is applied to an adjustable filter G which selects the desired harmonic frequency equal to (F+f)(p+f)/m, where r is an integer which may be varied by adjustment of G. It is shown mathematically that the final output frequency has good stability, and that by suitable selection of the frequencies of the oscillators and the multi-vibrator, and of the appropriate harmonic, that a wide frequency band may be continuously covered by adjustment. The example described involves the selection of one of 25 different harmonics by filter G to provide a series of sub-bands and provides a frequency stability of 2 x 10-<5> and a frequency band of 2500 kc/s. to 5000 kc/s. The filter G may comprise a multi-stage tuned amplifier, and the output from G may be applied to synchronize a third oscillator H which may be simultaneously adjusted with G. Additional frequency multiplying stages may be included.
