Abstract: 784,939. Welding by pressure. GENERAL ELECTRIC CO., Ltd. Aug. 16, 1955 [Aug. 23, 1954], No. 24518/54. Class 83 (4). In pressure, particularly cold pressure, welding a pair of tubular members 1, 2, an outwardly directed flange 10 is formed on one member in a plane substantially at right angles to the axis of the member, the flange and part of the exterior surface of the other member are surface prepared for welding, the other member is placed within the one member between a pair of tool surfaces 13, 15 and relative movement is caused between the tool surfaces to bring them opposite and separated by a gap whose width is such as to give the correct percentage reduction for welding, the relative movement causing firstly turning of the flange to bring it into contact with the exterior surface of the other member and secondly causing extrusion of material from between the tool surfaces to effect welding. In an embodiment an annealed oxygen-free copper container or can 1 of a transistor device, provided with a flange 10, is fitted in a die 11 with the flange in a recess and an annealed copper closure member 2 carrying a germanium transistor unit 5 and'provided with a flange 9 is fitted into the can 1. Both the flanges may have been scratch brushed but preferably the flange 9 is electrolytically gold plated after suitable cleaning. A top tool 12 apertured for leads 4 from the unit 5 and having a cylindrical welding surface 13, a cutting edge 14 and a further cylindrical surface 17 is pressed downwardly to firstly bring the flanges together against the surface 15 of the die and secondly to extrude the metal of the flanges upwardly until the edge 14 enters the die hole 16 and cuts off excess metal. The sealed can is finally ejected from the die by the tool 12. The operation may be carried out in dry nitrogen. Specification 748,015 is referred to.

Filed: 1920-07-08
Abstract: 169,441. Latour, M. Aug. 21,1915, [Convention date]. Void [Published under Sect. 91. of the Act]. Thermionic oscillation generators.-A thermionic tube having no retroactive coupling is caused to generate continuous oscillations by means of an auxiliary source, preferably a self-osciilating valve, acting on the grid circuit of the power tube. The plate circuit of the tube is supplied with alternating or pulsating current, preferably from a dynamo producing rectified currents having substantial voltage-fluctuations, so that there also exists a continuous-current component in the power circuit. This provides two means of selection at the receiving station, one depending upon the wave length emitted, and the other upon the superimposed note due to the frequency of the alternating-current supply. The filament of the power tube may be heated by alternating current supplied to the same dynamo. Vacuum or gas rectifiers may be used in combination with an alternator for supplying the plate voltage.

Title: An apparatus for training the ocular muscles and estimating binocular vision
IPC: A61H5/00
Filed: 1924-10-20
Abstract: 241,387. Smith, K. R. Oct. 20, 1924. Eye appliances.-Apparatus for estimating binocular vision and exercising the ocular muscles comprises an eyeshade A attached to one end of a lath B upon which slides a diaphragm D and a card holder C. The card holder C is positioned for the appropriate interpupillary distance and the sliding diaphragm D is placed at the position X at which position the letter A is seen with the right eye only and the letter G with the left eye only, the intervening letters being observed with both eyes. Movement of the diaphragm D towards the observer reduces the extent of binocular vision and renders' more of the extreme letters visible to a single eye only, until a position of the diaphragm D is reached at which half of the letters are seen by each eye and none by both simultaneously. Should binocular vision be defective, before this latter position is reached the letters will appear to run together or be partly obliterated and the direction of movement of the letters will give an indication of the character of the defect. The apparatus may be used as an exerciser for the muscles of the eye by sliding the diaphragm D, so that the defect may be corrected if due to the habit of using one eye insufficiently. The diaphragm D may be fitted with a shutter to permit the use of one eye only and the shade A may be provided with an aperture L for the examination of the surface of the cornea.

Title: Improvements in or relating to apparatus for the manufacture of plastic foam
IPC: B29B7/74
Filed: 1959-07-20
Abstract: 907,036. Making synthetic resin foam. KREIDL, W. H. July 20, 1959 [July 18, 1958], No. 24914/59. Class 14 (1). [Also in Group II] Apparatus for making plastic foam from a two-component resin source comprises a chamber 12 in which the first component is pneumatically foamed, a mixer downstream of the chamber in which the foam is mixed with the second component, a supply container for each component, and pneumatic conveyer means supplying the components to the chamber and mixer. Vnlves 11 and 15 for the two components and 24 for the air are operable by a common handle 14, the proportions of the components and air being predetermined by the pre-set regulating valves 51, 52, 53. The conveyer means are supplied by a common pressure source and are so designed that the volume supplied per unit time is dependent on the pressure, the compressed air required for foaming being taken from the same source so that the ratio between the volumes of air supplied to the chamber and the first component and the second component supplied to the mixer are independent of the pressure. In operation, depression of the handle 14 opens valve 15 whereby air enters the chamber 12 via line 44 and a perforated plate 40. Further depression of the handle opens valve 11 permitting the first component to pass through the duct 9 on to plate 40 and form a coarse foam in the chamber 12, from which, due to pressure, it is forced through a filter element 18 (thereby forming a fine foam) to a chamber 50 and thence via duct 45 to the mixer 22. A further depression of the handle opens valve 24 and permits the second component to enter the mixer via line 43 and inlet 48, whereby the foamed first component is mixed with the second.

Title: Method and apparatus for simultaneously plating and machining or lapping metal surfaces
Inventor: BAILEY JOHN MAXWELL
IPC: B24B33/02
Filed: 1958-08-05
Abstract: 853,742. Finishing metal surfaces by electrolytic plating and polishing. CATERPILLAR TRACTOR CO. Aug. 5, 1958, No. 25011/58. Class 41 [Also in Group XXIII] Metal surfaces are finished to precision limits by lapping and simultaneously depositing a metal thereon electrolytically. Preferably the metal surface is immersed in an electrolyte e.g. of a chromium salt, and the anode comprises an abradant member having metal inserts in the abradant surface as electrodes, the member moving across the metal plated surface. In a suitable apparatus for making a fuel pump cylinder, the cylinder body after normal machining and grinding is mounted at 10, Fig. 1, between two clamps 14, 15 and inside is mounted the anode and lapping member 21 comprising alumina or similar abradant made to the required dimensions. In the surface of the alumina are helical grooves 23 in which are mounted metal strips 22, connected through a collector ring 24 to a source of electrical energy. The anode member is reciprocated and/or rotated within the member 10, and as plating proceeds, any uneven surface of the plate is removed by grinding, until the whole surface is to the required size of the lapping member. The electrolyte is circulated from the bath 13 through pipe 38 and is forced upwards between the surface of the workpiece and the lapping member. In alternative constructions of the lapping member (1) it consists of a series of metal discs threaded on a rod with alternate rather larger discs of abradant; (2) the body consists of metal e.g. lead, with an outer skin of abradant, the vertical slots holding the anode members being insulated from the metal body. The temperature of the electrolyte is adjusted to take into account the size of the finished pump cylinder when cold. Members of square or elliptical cross-section may be made similarly, and also the plunger to fit exactly the pump cylinder using a cylindrical lapping member with an internal abradant surface and anode inserts.

Title: Improvements in or relating to directional antenna
Filed: 1929-08-16
Abstract: 318,619. Marconi's Wireless Telegraph Co., Ltd., (Assignees of Lindenblad, N. E.). Sept. 7, 1928, [Convention date]. Directive signalling. - A series of linear antennµ which are long relatively to the working wave-length, are collaterally spaced and are so tuned and energized as to be the seat of stationary waves. Fig. 3 illustrates the directional lobes 34, 36 and 30, 32 produced by a pair 14, 16 of such antennae, energized from a source 20 in phase opposition through tuned circuits 22, an impedance 26 being interposed, as shown, to separate the standing-wave systems on the aerials from the feed lines 24. By stagger. ing transversely the open ends of the aerial couple 14, 16 to an angle a equal to the angle made by the principal lobes with the longitudinal axis, the lobes 34, 36 are practically merged into the lobes 30, 32 as shown in Fig. 4. The spacing D between the aerial is such that D cosec. a is equal to an odd number of half wavelengths. In order to secure a unilateral lobe 30, Fig. 5, the primary couple 14, 16 is backed by an auxiliary couple 114, 116 spaced apart from the first by a distance d such that d cosec. alpha equals an odd member of quarter wavelengths. The aerials 114, 116 may be energized directly from the source 20 in phase quadrature, or they may be energized by reflection from the primary aerials 14, 16, and be tuned by a trombone slide so as to favour the production of standing waves. In the latter case the spacing is adjusted empirically. The conductors 114, 116 may be artificially lengthened by the insertion of looped sections. Fig. 8 shows two tiers of aerials 50, 52 forming a system A for horizontal transmission, the directivity of which is sharpened in azimuth by a similar system B arranged in broadside. Fig. 10 shows a modified aerial arranged to give a vertically-polarized radiation. The conductors 70, 72, 74 point in the direction of desired transmission in azimuth, whilst the angle of stagger a (between the open ends of the antennae pairs) determines the angle of elevation of the beam. The angle a remains constant over a considerable range of tuning.

Title: Selenium rectifiers and methods for their manufacture
IPC: H01L21/12
Filed: 1951-10-31
Abstract: Relates to selenium rectifiers having counter-electrodes made of Cd-Bi or Cd-Bi-Sn alloys.  According to the invention in the manufacture of the alloys the starting material comprises a Cd-Bi or Cd-Bi-Sn composition which differs from eutectic proportions in that there is a small deficiency of Cd or a small excess of Bi or Bi-Sn. The solid alloy may conform to eutectic proportions, i.e. 53.9 per cent. Bi, 25.9 per cent. Sn, 20.2 per cent. Cd or 60 per cent. Bi, 40 per cent. Cd or may by comparison with eutectic requirements contain a small excess of Bi or Sn or a small deficiency of Cd.  This small excess or deficiency may be 0.01 per cent. or more whilst retaining a solid alloy which is substantially eutectic.  Preferably any eutectic departure should not mean a melting point higher than 2 DEG C. compared with the eutectic melting point.  The essence of the invention is to insure that the solid alloy does not contain an excess of Cd.  In one manufacturing example for a counter-electrode of Bi-Cd about 1 per cent. of Bi is added to a melt of eutectic proportions.  Another example quotes the addition of 1 per cent. Bi-Sn to eutectic melt of Bi-Sn-Cd and the addition contains Bi and Sn in the same relative proportions as the eutectic of Bi-Sn-Cd.
