Patent GB-163014-A (GB)
Abstract: 163,014. Patent-Treuhand-Ges. f³r Elektrische Gl³hlampen. May 7, 1920, [Convention date]. Wire.-In making tungsten wire, particularly for electric lamp filaments, a blank consisting of rods which contain or are bound together to produce in their cross-section zones differing from one another as regards their composition, chemical or physical properties and relative quantities or qualities, is drawn and then submitted to a heat treatment so that the crystals form uniformly along the length of the wire. The length of the crystals in the direction of the axis of the wire may exceed the diameters of the wire several times. The blank may differ in competition from the axis to the circumference or from side to side, or may contain different sectors. The blank may consist of a casing into which circular, rectangular or other structures of desired composition are inserted, the casing or core consisting of pure tungsten, tungsten and thorium oxide, or tungsten alloyed with metals or metalloids such as molybdenum, uranium, thorium, tantalum, vanadium, chromium, carbon, or phosphorus or mixtures of compounds thereof, or with other elements dissolved or admixed therewith. As examples, the casing may consist of pure tungsten and the core of tungsten containing thorium dioxide, or the casing may be of tungsten containing thorium dioxide and the core of pure tungsten or tungsten containing a small quantity of thorium dioxide. The thorium oxide &c. may be introduced into the blank by superposing or embedding or introducing into holes in the blank layers of powder, by inserting sintered or mechanically-worked bodies or by saturating with solutions which only penetrate the outer layers, or by repeated saturation with different solutions and subsequent chemical conversion by fluids or gases. The wire may be regularly heated throughout its whole length or may be heated by passing the wire through a hot zone. The latter method may be effected by heating sections of the wire in turn by an electric current or by surrounding with a hot cylinder or ring.

Abstract: 860,669. Coating with metals. GENERAL MOTORS CORPORATION. May 13, 1959 [June 16, 1958], No. 16416/59. Class 82(2) [Also in Group XXII] In making brazed and coated steel tubing, a steel strip is progressively rolled into tubular form by passing the strip longitudinally through the rolls, a supply of zinc or zinc alloy is continuously fed into the tubing, the tubing is heated to vaporize the zinc or zinc alloy, and the tubing is immersed in a bath of copper or copper alloy so that the metals form an alloy which coats the interior thereof and brazes the seam. A flat steel strip S if fed from a reel 10 to a mill 12 having rollers 14, 22 and a swaging device 24 to form the strip into circular cross-section. A wire 26 of zinc or zinc alloy is fed by rolls 42 from a reel 40 through a tube 44 into the interior of the tubing before it is fully formed. A non-oxidizing gas is fed through a pipe 30 which enters the tubing at the point of supply of the zinc wire and extends within the tubing towards the swaging device. The formed tubing is heated to above 1665‹F. in a furnace 32 supplied with the non-oxidizing gas and the zinc or zinc alloy is vaporized. The tubing while still in the furnace is passed through a bath 34 of molten copper or copper alloy supplied with wire 54 to automatically maintain a constant level. The molten metal migrates through the seam 16 and forms with the vaporized metal an alloy which coats the inner surface of the tubing. The tubing then passes through a cooling chamber 38 supplied with the non-oxidizing gas. The gas may be by volume 10% carbon monoxide, 18% hydrogen, 4¢% carbon dioxide, 1% methane and balance nitrogen or may comprise nitrogen, helium, argon, carbon monoxide &c.

Filed: 1952-06-30
Abstract: 720,334. Television. RADIO CORPORATION OF AMERICA. June 30, 1952 [July 18, 1951], No. 16433/52. Class 40 (3). In an apparatus for recording television image signals, the raster of a cathode-ray tube modulated in accordance with the signals is imaged on a continuously moving record strip, such as a photographic film, with the line direction of scan parallel to the direction of film movement, whereby the recorded lines appear as shown in Fig. 4. With double interlaced scanning the two fields A, B appear separately and the lines are arranged to be spaced apart more than normal to prevent loss of detail during play-back. It is not intended that the images should be recognizable, although they are sufficiently clear for editing purposes. To regenerate the signals, the recording apparatus is re-arranged so that the cathode-ray tube produces a constant intensity spot and a photo-tube is positioned to receive the light passed through the film. Spot-wobbling is employed to ensure a tracing of the lines should slight misalignment of the raster occur. Preferably the film is of the reversal type, although the record may be obtained by contact print from a negative film.

Title: Improvements in and relating to voltage regulating systems
IPC: H02P9/10
Filed: 1926-07-02
Abstract: 254,737. British Thomson-Houston Co., Ltd., (Assignees of Stevenson, A. R.). July 2, 1925, [Convention date]. Regulation, automatic; systems depending on two or more machines.- To improve the stability of a high volttage long-distance transmission system under load fluctuations the field current transients due to armature reaction in the alternators are prolonged by exciting means such as an unsaturated series wound machine which will have a voltage rise in proportion to the current flowing in the field circuit so that the field circuit will rise exponentially, combined with regulating means to stop the indefinite rise and to limit the transient when the voltage of the alternate reaches its normal value. The exciting means furnishes a negative resistance which is adjusted so as to be substantially greater than the ohmic resistance of the entire circuit when the alternator voltage falls below its normal value. Fig. 2 shows an alternator 1. supplying a line 2 through transformers (not shown) and excited by a series exciter 4. controlled by a Tirrill regulator, shown as a contactor 6, so that a fall of voltage removing a shunt about the exciter field 5 will increase the effective negative resistance of the exciter. Normal conditions are restored when the alternator voltage returns to normal. According to a modification (Fig. 3) a series wound rotary converter 9 is used as exciter and an inductive load 11 causing sufficient demagnetizing armature reaction remains connected across the slip rings until a fall of voltage in the line 2 causes a contactor 17 to open the circuit of a contactor 12 holding this inductive load in circuit. In a further modification (Fig. 4), a winding 21. arranged upon the magnetic circuit of the series-wound exciter 19 in such a way as to have no initial inductance with either armature or field circuits, for example by suitable winding upon slotted field yokes, is connected across the exciter armature by a contactor 22 whilst the line volts are normal, so saturating a portion of the field yoke. Upon the occurrence of a load sufficient to depress the alternator voltage and produce a field current transient the contactor 22 opens and the effective negative resistance, of the exciter is increased, so that the transient is prolonged and the alternator voltage quickly restored, whereupon the winding 21 is again energized by the contactor 22 closing.

Filed: 1976-04-23
Abstract: 1535943 Radio navigation INTERNATIONAL STANDARD ELECTRIC CORP 23 April 1976 [25 April 1975] 16660/76 Heading H4D An airport surface traffic control system is expanded from a known landing system, wherein the landing aircraft radiates interrogating pulses containing an identification signal for the aircraft and in which the directions of arrival of the pulses are determined by an azimuth- and an elevationmeasuring unit 6, 7, guidance information is transmitted from a transmitter to the aircraft, and indicated there, whereby after touchdown the coordinates of the position of the aircraft 10 are determined, compared with the coordinates of a reference point 5, and the result used to provide coarse taxiing guidance information which is transmitted to the aircraft in coded form, is decoded and indicated therein. Additional azimuth-measuring units 8, 8a, 8b, co-operate with azimuth-measuring station 6 of the landing system to measure the directions of arrival of the interrogating pulses, and the aircraft coordinates are calculated in a central station 9 in known manner by a process computer or by an existing air-trafficcontrol computer, Markings 4 which indicate paths to be followed by the aircraft are provided on the runway 1, taxiways 2 and parking places 3, and bifurcations in these markings act as the reference points 5. A cross-pointer instrument 31, 32, indicates the coarse taxiing guidance information on board the aircraft, the horizontal pointer 31 moving towards the datum marks 37 as the aircraft approaches the bifurcation 5 and the vertical pointer 32 indicating that the aircraft is to turn right at this point. If pointer 32 were between marks 36 this would indicate that the aircraft was to taxi on straight ahead. Fine taxiing guidance for the aircraft is provided by a television camera on the aircraft directed towards the runway and producing an image of the markings 4 on a screen 33, the markings coinciding with datum marks 36 when the aircraft is directly above them. The area of the image shown is adjustable as a function of taxiing speed. An alternative embodiment uses radio-active markings and a Geiger-Mueller counter tube instead of a television camera. The image appears on screen 33 only after a switch has changed over from the mode "landing" to the mode "taxiing guidance". This enables the same cross-pointer instrument 31, 32 to be used to indicate the azimuth and elevation during landing, although a separate indicating instrument may be used. Taxiing instructions such as "stop", "wait" or "go on" can be given via signal lamps 35, or audibly, and the distance to be travelled to the bifurcation at which the aircraft has to turn off is indicated at 34.

Title: Improvements in and relating to gas blast circuit-breakers
Inventor: BOERSMA RINTJE
IPC: H01H33/82
Filed: 1968-04-08
Abstract: 1,217,053. Gas blast switches. COQ N.V. 8 April, 1968 [14 April, 1967], No. 16831/68. Heading H1N. In a gas blast switch of the kind in which the contacts 21, 26, during opening, first move together until the rearmost one is arrested by a stop 30, both contacts are moved by compressed gas from the extinguishing chamber and the leading contact 21 is arranged to be moved back to reclose the contacts and a blast valve after a delay. The contact 26 carries a piston 27 movable in a cylinder 25 which can be supplied with compressed SF 6  gas from a chamber 33 or vented to an outer chamber 38 by a valve 44. The contact 21 is attached to a piston 23 slidable in a cylinder 22 which can similarly be supplied with compressed gas or vented by a valve 50 operated by a piston 55. To operate the switch a rod 58 is pulled to the right to change over valve 44; the piston 27 is thus driven upwards, contact 26 pushing contact 21 before it to separate the parts 31, 32 of a blast valve. Compressed gas thus enters the contact space below piston 23 driving contact 21 to its fully open position, contact 26 being arrested by the stop. After a delay necessary to fill pipe 57 valve 50 is changed over to admit compressed gas to the inside of piston 23 so that a spring 24 recloses the contacts and valve 31, 32. In a modification (Fig. 3, not shown) the supply to pipe 57 is obtained from the space below piston 23 allowing the rod 58 to be released earlier so that contact 26 returns to the position shown before contact 21 reaches its open position, thus causing a larger interrupting gap and preventing contact 21 striking contact 26 during reclosure and damaging the arc resistant surfaces 64, 65 which are of sintered tungsten alloy. The contacts 21, 26 do not meet in the closed position shown and connection is made through fixed contacts 29. The chamber 33 is mounted inside insulating tubes (2, 3, 4) in an earthed tank (1) the space between the tank and tubes being filled with insulating fluid (Fig. 1, not shown). The terminals 10, 11 of the switch are connected to conductors (14, 15) by contacts 5, 12, 6, 13. The blast gas passing through the nozzle contacts 21, 26 to low pressure chambers (34, 35) is recirculated through a filter (39) by a pump (40). The space 38 is preferably separated from the chambers (34, 35).
