Title: Contact device for calling dials
IPC: H04M1/31
Filed: 1944-05-05
Abstract: 599,308. Impulse transmitters. AUTOPHON AKT.-GES. May 5. 1944, No. 8534. Convention date, May 21, 1943. [Class 40 (iv)] A calling dial is provided with contacts which are made only during the return movement of the dial. During the advance movement of the dial, the pin b, fixed to the blade spring f, holds the contacts k separated. During the return movement, the impulse disc is rotates and a projection m thereon engages the blade f to remove the pin from between the contact springs which then make contact until the dial reaches its rest position when the cam n acts on the stud s to separate the contacts k, allowing the pin b to resume its position between the springs. Springs k<1> are the usual off-normal springs. The springs k may be used to shortcircuit the speaking wires during impulsing, having the following advantages over the use of the off-normal contacts for this purpose: (1) the subscriber may make the preliminary rotation of the dial and then wait for dial tone before releasing; (2) the subscriber is more likely to notice a busy tone emitted by the exchange during dialling ; (3) it enables the subscriber to save time in an arrangement such as described in Specification 596,662 where the speaking direction of subscribers' amplifiers is changed over by either subscriber dialling 1.

Title: Lasers including crystals of group iii-vi semiconductor compounds
IPC: H01S5/30
Filed: 1972-02-24
Abstract: 1322147 Lasers; semi-conductor devices WESTERN ELECTRIC CO Inc 24 Feb 1972  [12 March 1971] 8580/72 Headings H1C and H1K [Also in Division C4]  A semi-conductor laser comprises a crystal of a Group III-VI compound having a layered, mica like structure, the laser output being parallel to the plane of the layers and being polarized so that its electric vector is orthogonal to the layers. The crystal may be pumped optically, e.g. by a nitrogen laser as in Fig. 1 (not shown), or by current injection. The crystal may contain a P-N junction 22, Fig. 2, which can be reverse biased as shown, or forward bias. In Fig. 2 current is supplied by an electrode 23, and a similar electrode on the opposite, hidden face. The output is along arrow 26, and is polarized in direction 27. Line 16 represents the crystal's c axis. A Schottky diode may be used, Fig. 3 (not shown), current being injected through an insulating layer such as occurs naturally on the surfaces of some III-VI compounds. A double heterostructure laser is shown in Fig. 5, where 56 and 57 are electrodes, 51 is N type gallium selenide with Ge doping, 52 is similar but with less dopant, 53 is the emissive region of P type (zinc doped) gallium aluminium selenide, 54 is similar but copper doped, and 55 is similar to 54 but has a higher dopant concentration. Such a structure can produce continuous room temperature outputs. The structure is suitable for use as an amplifier in which case the input would be a focused beam, and the input face would be cut at Brewster's angle. Materials.-The optically pumped crystal may be GaSe which gives an orange output, 6010 Š; it may be doped with Cu, Si, Ge, Sn, C1, Zn, Cd or the like. Green outputs are obtained from GaSe 0.7 S 0.3 , and a blue output is predicted for GaS. If Ga 1-x Al x Se is used the visible spectrum can be covered by the choice of x. The band gaps of these and other III-VI materials, with the corresponding outputs, are given in Fig. 4, the range extending from 4800 Š into the infra-red. Manufacture.-Conventional techniques are used, e.g. Bridgman or Czochrolski methods; gallium aluminium selenide can be grown by liquid phase epitaxy. The oscillators use natural or cut surfaces for their resonator reflectors, the polarized output being a natural feature. Because of the devices' layered structure they may be attached to heat sinks by grease rather than by the bonding necessary with non-flexible devices.

Abstract: 273,407. Westinghouse Brake & Saxby Signal Co. April 1, 1926. Induction relays.- Relays for railway signalling which are responsive to current of one frequency and not to current of another frequency such as the power supply frequency have opposite torques produced on an induction disc by two sets of poles, the rotating field for each set of poles being produced by the combined action of a winding common to both sets of poles and a second independently energized winding differently associated with different portions of each pole. As shown in Fig. 1 the disc 10 is placed between pairs of poles 5, 5a and 3, 3<a> the former having a greater cross-section than the latter and being provided with shading rings 7, 7<a>. A winding 8 is provided on a magnetic yoke 2 common to both poles and a winding 9 is wound on the slotted poles in the manner shown in Figs. 3 and 4 so that the flux produced by this winding is in the directions shown in Fig. 5. Normally the disc experiences equal and opposite torques with both windings energized at the predetermined signalling frequency but when the winding 8 is de-energized due to the bridging of the rails 15, 15a by the axles C of a train passing over the insulated section AB the relay disc is rotated to close a switch 13 controlling the signal S. The relay is retained in its normal position by a spring or counterweight.

Title: A Sequence Control System
IPC: G03G21/14
Filed: 1967-02-27
Abstract: 1,168,864. Programmed control of copying; contact printing. MALLORY TIMERS Ltd. Feb.27, 1967 [Feb. 28, 1966], No.9189/67. Headings G2A and G3N. A control system for an appliance having a predetermined sequence of operations comprises a ring counter, each state of which represents an event in the sequence, and a shift register, identifying the state of the appliance within the sequence, the counter and register being interconnected so as to energize elements of the appliance during predetermined events of the sequence of operations. As shown, a copying machine has rolls 19, 20 between which is fed an expendable sensitized intermediate material. An original is inserted between the intermediate and a sponge roller 21 and a rubber roller 22, and moved to an exposure station 23 where it is held by a clamp 24. After development, the intermediate is moved to a storage station 6 and the copied original ejected to a bin 25. Copy paper is then fed from a supply 27 on to the intermediate by a solenoid 30 and the intermediate and copy paper transferred to a developing station 28 where it is held by the clamp 24. The intermediate is then transferred to the roll 20 and the copy ejected to a bin 29. The movement of the intermediate is determined by a rotation of a roller 26. At each rotation of the roller a pawl 31 is seated in a notch 32 and opens a switch 33 in the supply to a motor, not shown, driving the roller. A further rotation of the roller is initiated by the energization of a solenoid 34 which withdraws the pawl 31 and consequently closes the switch 33. Since unexposed portions of the intermediate lie in the exposure, storage and development stations when one copy has been made, or after a number of copies have been made, the intermediate is reversed three steps to conserve material. To ensure registration the pawl 31 approaches the notch 32 from one direction only and for reversing the intermediate it is driven past the notch 32 and the motor reversed so that the notch approaches the pawl in the forward direction. A page of a book is copied by inhibiting the rollers 21, 22 by a switch, not shown, and lifting the clamp 24 manually, the intermediate feed being effected by successive depressions of a start button, not shown. The operating cycle of the machine is coordinated by an electronic circuit. The steps in a programmed sequence being set up by a ring counter and the appropriate sequences by a shift register having a separate stage for each of the exposure, storage and development stations. The inter-connection between the ring counter and shift register being effected through a logic network.

Abstract: 550,951. Storage batteries. TAYLOR, P. W. July 21, 1941, No. 9202. [Class 53] [Also in Group XXII] In an accumulator, intended particularly for use in torches in substitution for a dry battery, the electrodes b, b<SP>1</SP> extend in opposite directions from the end walls of the casing a and are secured to these walls by material d cast into position to form a liquid-proof joint. The casing may be of ebonite, celluloid, glass, resin compositions such as polystyrene resin, or other suitable insulating material, and in the construction shown is formed with an internal flange f at one end, the other end being completely open. Fig. 6 shows the mould used for casting the metal d at the flanged end of the casing, comprising a core h with a slot to accommodate the electrode b, a sleeve n which surrounds the casing, and a block m with a pouring opening h. The electrode b projects from the top of the core, so that it is secured in the cast metal. The other electrode b<SP>1</SP> is secured in an end cap o in a similar way, and the cap is then sealed to the end of the casing with a suitable cement. The plates b, b<SP>1</SP> are spaced closely together, the interspace being almost entirely filled by a separator strip u which is formed with a longitudinal channel w and extends across the entire width of the casing. A similar strip u<SP>1</SP> is in contact with the surface of the plate b<SP>1</SP> opposite the filling aperture e. A limited quantity of electrolyte is used which tends to flow along the channels u<SP>2</SP> and to spread over the surfaces of the plates, which keeps it from the aperture e. In a modification, the body of the casing is formed of an open-ended lead tube, one end being closed by lead which is cast into position and holds one electrode, whilst the other end is sealed by a cap of insulating material, such as polystyrene resin, in the centre of which the other electrode is secured by lead cast into position.
