Title: Telegraph transmission system
IPC: H04L25/49
Filed: 1945-03-29
Abstract: 594,795. Telegraphic transmission systems. STANDARD TELEPHONES & CABLES. Ltd. (International Standard Electric Corporation). March 29, 1945, No. 7963. [Class 40 (iii)] In a telegraph transmission system in which a character is determined by the time interval between a signal impulse and a start impulse, the spaced impulses are obtained by applying the start impulse directly to a transmission line and to a portion of an artificial line selected in accordance with the desired character, the spaced impulse being derived from the end of the selected portion of the artificial line or reflected back to the beginning of the artificial line before passing to the transmission line. The start and signal impulses may be of opposite polarity, and if the start impulses are continuously produced the artificial line is terminated by its characteristic impedance to prevent reflection of impulses from the end of the line. In the arrangement shown in Fig. 4 the impulse generator comprises a battery 21, a variable resistance 22, a switch 24 and an inductance 23 connected to the transmission line 3 through a condenser 25 of small capacity and a rectifier 26. The artificial line 2 comprises sections, including switches 11, 12, 13 ... controlled by a keyboard operating so that when the artificial line is opened at any selected point the switch 24 is also opened and an impulse is produced at the terminals of the inductance 23. Condenser 25 permits the passage of the steep front of the impulse and the rectifier 26 prevents the reflected impulse from passing to the generating circuit. In a modification, Fig. 5 (not shown), a condenser, normally charged, is discharged by the closure of a switch operated from the keyboard. In a' further arrangement, Fig. 6, the start impulse from a generator 1 is fed to the line 3 by a valve 30 which is made conducting by the impulse which is simultaneously fed through a rectifier 40 to the artificial line 2. The impulse taken from the selected length of artificial line 2 is determined by the closed switch a, b, c, d ... and passes to the grid of a valve 31 which transmits the delayed impulse to the line. Condensers 32, 33 prevent the passage of surges due to the closures of the key contacts. In a modification of Fig. 6and not employing valves, Fig. 7 (not shown), the impulses from the generator and artificial line are applied to the transmission line through load impedances with suitably disposed rectifiers to prevent the passage of reflected impulses to the impulse generator. In one arrangement, Fig. 3 (not shown), in which the artificial line consists of T sections and comprise a series of inductances, the selectively operated switches are arranged to short circuit the line at the mid points of the inductances so that the reflected and start impulses are of opposite polarity. The keyboard of the transmitter may incorporate an arrangement operating so that the impulse generator is operative solely when a key is actuated.

Title: Modulation and detection of electromagnetic waves

Abstract: 1,211,565. Photo-electric signalling systems . COMPAGNIE GENERALE D'ELECTRICITE. Feb. 19, 1968 [Feb. 28, 1967], No.8046/68. Heading G1A. [Also in Division H4] A monochromatic light beam is amplitude or phase modulated by passing it through a semiconductor or semi-metallic crystal disposed in a magnetic field at a constant preferably low temperature in an enclosed space, the absorption characteristic of the crystal which is associated with the interband transitions between the energy levels known as the Landau levels being varied by causing the free carriers of the crystal to perform absorbent transitions between the Landau levels, the crystal being transparent to the light beam in the absence of the magnetic field. The free carriers may be caused to perform absorbent transitions by varying the energy distribution curve of the free carriers or by varying the number of free carriers. To vary the energy distribution curve an electric field may be applied by means of capacitor plates on either side of the crystal or by means of induction created by a solenoid disposed around the crystal. To vary the number of free carriers the crystal may be irradiated with electro-magnetic radiation (photo-electric effect), or electrodes associated with the crystal may be connected to a modulating current, one of the electrodes forming an emitter which injects free carriers into the crystal, or free carriers may be injected into the crystal by means of a layer of a semi-conductor on the crystal connected to a modulating current, the semi-conductor layer being of opposite type to the crystal and thus forming a PN junction, or the number of free carriers may be effected by applying an electric field to the crystal which is sufficient to create an ionisation by impact from an appropriate impurity level. Alternatively the free carriers may be caused to perform absorbent transitions by modulating the magnetic field within the enclosed space. The magnetic field may be created by an electro-magnet or a super-conducting winding the cooling means of which being associated with means for maintaining the low constant temperature within the enclosed space. The crystal may comprise indium arsenide, cadmium telluride, antimony, bismuth, arsenic, indium antimonide having N-type conduction, or elements or compounds of elements in the II-VI groups of the Periodic Table. The windows of the enclosed space through which the light beam passes are associated with selective filtering means. A detector for detecting the amplitude modulation of the light beam may be identical to the modulating device. The absorption of a photon results in the excitation of a free carrier which passes from the fundamental level to a higher energy level at which its mobility is different i.e. the electrical conductivity (resistance) of the crystal is modulated. This conductivity may be measured by electrodes disposed on the crystal and connected to the input of a measuring bridge.
