Title: Improvements in or relating to Telephone Exchange Systems.
IPC: H04Q3/54
Filed: 1968-06-25
Abstract: 1,184,508. Automatic exchange systems. SIEMENS A.G. 25 June, 1968 [26 June, 1967], No. 30319/68. Heading H4K. In a PBX, main exchange line circuits are interrogated to detect dialling tone from the main exchange before an automatic number sender is started, and to detect equipment engaged tone from the main exchange by examining the line circuits during pauses between digits being sent. An automatic number sender is employed to send the number corresponding to an abbreviated code dialled by the calling extension. When a number sender and a main exchange line circuit have been seized and are ready to send, a common control circuit seizes a common tone detector and connects it to the main exchange line circuit. When dial tone is returned from the main exchange the tone detector starts the automatic number sender and retires. If dial tone does not appear in a given time the tone detector causes the connection of busy tone and then retires. When a main exchange line circuit is occupied with the sending of digits it marks itself available for inspection during intervals between digits and the common control circuit seizes the common tone detector to look for equipment unavailable tone returned from the main exchange. Should such a tone be detected the connection is released and busy tone is sent to the calling extension.

Title: Device for controlling the limits of movement of a recording element
IPC: G07C5/00
Filed: 1969-06-18
Abstract: 1,242,015. Recording-apparatus. KIENZLE APPARATE G.m.b.H. June 18, 1969 [June 21, 1968], No.30859/69. Heading G1J. [Also in Division F2] A device for controlling the limits of movement of a writing element 8, 9 in a direction T substantially perpendicular to the direction of movement of a recording-medium comprises a transmission linkage 5, 11, 12 providing operational co-operation between a driving element 1, 2 and the writing element 8, 9 in such a way that there is no component of driving movement acting on the writing element 8, 9 in the direction T when it reaches a selected one of respective critical positions defining the limits of its movement. A transmission lever 5 is urged by a spring 6 against a fixed stop 7 and, when pulses are supplied to an electromagnet 1, the armature 2 thereof causes the lever 5 to oscillate about an axis 4 between the stop 7 and either a movable stop 13, or a fixed stop 17 if a magnet 16 is energized to move the stop 13 out of the path of the lever 5. The oscillating lever 5 drives a writing lever 8 through a slot 11 engaging a pin 12 in an arm 10 of the lever 8 and a writing pin 9 traces a narrow or wide bar diagram 19 or 20 according to which stop 13 or 17 is operative. The slot 11 has three arcuate parts 21, 23, 25 centred on the axis 4 and intermediate camming parts 22, 24. The parts 22, 24 transmit transverse components of motion to the writing pin 19 which cease precisely as the pin 12 enters a part 21, 23 or 25. The slope of the part 24 exceeds that of the part 22 thus increasing the transmission ratio at a stage when the pull of the magnet is greater.

Title: Improvements in or relating to vacuum evaporation of metals
IPC: C22B5/16
Filed: 1948-11-29
Abstract: 654,228. Coating with metals; evaporation of metals. EDWARDS & CO. (LONDON), Ltd., W., HOLLAND, L. A., and CUTTER, J. M. Nov. 29, 1948, No. 30882. [Classes 82(i) and 82(ii)] In a method of vacuum evaporation of metals the metal in wire or tape form is presented axially towards an open end of an evaporator and intermittently moved into the evaporator by a predetermined amount, the metal being preheated and finally melted to allow discrete particles to flow over the inside of the evaporator and thereby be evaporated. As shown, a length of wire 11 from a spool 12 is fed by means of a tension pulley 16 and a feed pulley 15 through a guide tube 13 into an evaporator 14 which may be in the form of an electrically heated coiled tungsten wire. The wire 11 is preheated and then melted, the molten particles falling on to the coils from which they are evaporated and may be deposited on a moving or stationary article. The wire may be advanced an amount equal to the length of the evaporator by a fluid operated diaphragm 32 connected to a rack 39 and pinion, a ratchet 27 and pawl 28 preventing reverse movement of the feed pulley. Instead of a rack and pinion the feed pulley may be rotated by a capstan device, Fig. 6 (not shown). The diaphragm and its spring return may be mounted outside the vacuum chamber and the remainder of the apparatus inside. The rate of advance of the wire may be such that one length just melts as the molten metal from the previous length is completely evaporated. In a modification, Figs. 3 and 4 (not shown), a pair of supports may move relatively to one another with means for moving the wire forward but preventing backward movement, or a piston and cylinder similarly equipped may be used, Fig. 5, (not shown). Two or more wires of different metals may be used to produce an alloy coating, the wires being fed at the same or different rates. The Provisional Specification also states that the advancing gear may produce a nick on the wire to aid in quick severing.

A semi-conductor device is made by stacking the parts of the device in a mould with a baseplate adapted to form an integral part of a housing for the device uppermost and acting as a loading weight and then heating to alloy or solder the parts together. In an example (Fig. 1), a gold antimony alloy member 3, silicon plate 4, aluminium foil 5, molybdenum plate 6, solder foil 7 and massive plug shaped base member 8 are stacked as shown in a graphite mould 1 and heated in vacuo or nitrogen to form a PN junction in the silicon plate and to form a unitary rectifier assembly. A housing member comprising a tube 11, through one end of which a metal tube 13 is sealed via glass bead 12, is electrically welded to the periphery of the flange 8b of the base member. After filling with protective gas the tube 13 is sealed by pinching off and if necessary welding or soldering its end about contact wire 14. If the various parts of the rectifier are of different areas a mould of stepped cross-section may be used to laterally locate the individual parts. In the mass production of such rectifiers, handling is facilitated by use of a single graphite plate constituting a plurality of moulds.

Title: Improvements in or relating to mechanism for recording automatically the course of ships and other vehicles
IPC: G01C17/00
Filed: 1926-12-08
Abstract: 286,382. Brown, S. G. Dec. 8, 1926. Recording by coordinates.-In apparatus for recording the course of a ship or other vehicle a marking device is adapted to record on a moving strip the degree of angular deviation from a given datum line and means is provided for indicating on the same ordinates which side of the said line the deviation is occurring. As shown in Figs. 1, 2 and 4, a cylinder 1 with oppositely directed spiral grooves 3, 4 is rotated in accordance with the deviation by a step-by-step motor 2 controlled by the ship's compass or other control means. Engaging with one of the grooves is a slider 5 pivotally mounted on a carriage 6 slidable along rods 7, the carriage having an arm 8 with a marking member in contact with a record-strip 9 controlled by clockwork or other mechanism. The cylinder 1 may be initially set by rotation from a milled knob 10. A scale 15 with two sets of graduations for degrees is arranged parallel to the cylinder and one set is adapted to be obscured by means of an apertured shutter 11 having a pin-and-slot connection with a balanced lever 12 attached to the slider 5 and moved in a vertical direction when the slider passes from one groove to the other at either end of its travel. If the E-W line is the given datum line the position of the shutter will indicate whether the deflection is north or south of said line. To produce a permanent record of this deviation a second marking member 16 on a carriage 17 with a slider 18 engages one of the grooves on the side of the cylinder opposite to that of the carriage 6 and is arranged to produce a record at 90‹ to that of the arm 8. These records may be distinguished by using differently coloured inks. In a modified form a single pen may be employed, the tilting of the slider 5 at the ends of its travel being utilized to make and brake an electric circuit, the circuit when complete causing a current to pass through the ink to vary its colour electrolytically to distinguish north and south deviations. In another form where two pens are employed a single carriage is provided, the main pen being supported from the mid point of the slider and the auxiliary pen carried at one end of the lever 12.
