Transformers.-The primary and secondary windings 1, 2 of the intervalve transformer described in the parent Specification are wound on tube formers 4, 5 which project from the ends of the windings and abut together, so as to leave an air gap between the windings. The diameters of the windings are made large relatively to their axial lengths, in order to reduce the selfcapacity of the windings. The core 3 is built up of rectangular laminae, each of which is cut across at one point, so that it may be opened out threaded through the coils, and then closed again. The cuts 3<a>, 3<b> of alternate laminae are arranged at different points of the magnetic circuit. The terminal board 7, core 3, and windings are supported by means of shrouding plates 9 in the form of iron or brass stampings, provided with internal supporting feet 14. The sides of the plates are bent over at 13 to engage edge bands 15 of copper or brass, which are insulated from the core and serve to complete the enclosure of the transformer. The ends of the windings are connected to spring plunger terminals 6, mounted on the terminal board 7. One form of terminal comprises a plunger 19 mounted in a cylindrical body 20, the lead being inserted through transverse holes 22, 23 in the plunger and body and held firmly in place by a spring 21.

Title: Improvements in incandescent electric lamps
IPC: H01K1/26
Filed: 1956-07-04
Abstract: 803,536. Electric incandescent lamps. GENERAL ELECTRIC CO. July 4, 1956 [July 13, 1955], No. 20724/56. Class 39(2) An electric incandescent lamp comprising a sealed envelope 1 having a concave light-concentrating reflector portion 1, an opposed transparent window portion 3, and a concentrated filament 5 located substantially at the focus of the reflector is characterized in that the reflector is highly reflective of visible light rays and also highly transmissive of infra-red rays, and a shield 13 is arranged adjacent to the filament and between the filament and the window 3, the shield being shaped and proportioned to intercept the radiation emitted directly from the filament toward the window. In the example the lamp 1 is of the sealed beam type comprising a glass reflector portion 2 and a lens or window portion 3 hermetically fused together, the reflector portion having previously been coated with a film 11 of semi-conductive material such as germanium, silicon, antimony-sulphide or selenium, covered by a single film 12 of dielectric such as zinc sulphide of such thickness as to reduce the infra-red reflectance. The film 12 of dielectric should have an optical thickness equal to one-quarter the wavelength of near infra-red light, and an index of refraction equal to the square root of the index of refraction of the semiconductor 11 in the same wavelength region. In an example a laver 11 of germanium of a thickness which transmits approximately 20 per cent of visible radiation is coated with a layer of zinc sulphide having an optical thickness of approximately 250 millimicrons. The filament 5, which is of any desired concentrated configuration, and preferably located at the focus of the reflector portion, is located approximately at the centre of a shield 13 which may be of spherical section. The shield is preferably constructed of highly reflective material such as iron, nickel, or molybdenum or a non-metal such as sintered alumina or magnesia. U.S.A.

Title: Method and apparatus for making hollow articles, particularly hollow blades for gas turbines
IPC: F01D5/14
Filed: 1953-07-30
Abstract: 734,648. Making hollow members, particularly turbine blades. CREEK, J. O. July 30, 1953 [Aug. 2, 1952], No. 21161/53. Classes 83 (2) and 83 (4). Extruding; stamping ; destructible cores.-In the manufacture of a hollow article, particularly a hollow blade for a gas turbine, a hollow workpiece 11<SP>1</SP> having a closed end 19 is squeezed laterally between dies 34 which provide relief of pressure at the closed end, and a deformable medium 23 is then forced into the closed end to enlarge the workpiece at the closed end by stretching the material beyond its elastic limit. A forged or machined block 11, Fig. 1 (not shown), is inserted in an impact extrusion die 12, Fig. 3, and is extruded rearwardly by a plunger 13. A stripper 21 removes the extruded workpiece on retraction of the plunger. If the block 11 is produced by die forging, the die 12 may be used as the batten die in the forging operation. The workpiece is then filled with an incompressible but deformable substance, such as Wood's metal, lead, lead-bismuth alloys, silicone, or rubber-like plastics, and is inserted in the cavity 37 formed between the laterally movable dies 34. The latter are slidably mounted in a block 29, Fig. 5, and have inclined end faces 35 which co-operate with end faces 26 on a bolster 24 to move the dies inwardly and close the cavity 37, when the block 29 is moved downwardly by a ram 41. Slight pressure is maintained on the deformable core by a second ram 40, during the squeezing movement of the dies, and when the latter are closed, the ram 40 moves downwardly to effect enlargement of the closed end. After removal the workpiece is heated to melt out the core and finishing operations are performed to complete the blade.

Abstract: 746,151. Pulse-radar; multi-stable state circuits. HAZELTINE CORPORATION. July 22, 1954 [July 29, 1953], No. 21420/54. Classes 40 (6) and 40 (7). A pulse radar with a P.P.I. display utilizes a three-gun three-colour shadow-mask cathoderay tube of the type described in R.C.A. Review, Vol. XI, June, 1950, p. 230, and the receiver output is connected sequentially through an electronic switch to the red, green and blue guns of the tube so that the colour of an image of a moving target changes but that of a stationary target does not change. In order to detect targets moving radially the switching frequency S is greater than the pulse-recurrence frequency P so that if a radial trace were fully brightened it would comprise a repeated sequence of red, green and blue spots, Fig. 5a (not shown), but to detect circumferential movement S=P/3 so that the display, if fully brightened, would comprise a repeated sequence of red, green and blue traces, Fig. 5b (not shown). The velocity of the target can be estimated from the rate of change of the coloured image. As shown in Fig. 1, the output from a 1 Mc/s. oscillator 10 is applied through a pulse generator 11 and 900/1 counting-down circuit 12 to trigger the transmitter 13 and sweep generator 30 which is coupled to a deflector coil 33 rotated synchronously with the aerial 14. The output A, Fig. 3, from pulse-generator 11 is also applied to a 3/1 ring counter 40 producing displaced outputs B, C and D which are applied through contacts b of switch 43 to inverting amplifiers 42r, 42g and 42b whose outputs, Fig. 4 (not shown), are applied as gating pulses to the suppressor grids of pentodes 49r, 49g and 49b. The output from receiver 20 is applied in parallel to the control grids of the pentodes and their anode outputs are connected respectively to the cathodes 28r, 28g and 28b of the tri-colour tube 26. An output from the counting-down circuit 12 is also applied to a 3/1 ring counter 44 whose outputs, Fig. 6 (not shown), are applied to amplifiers 42r, 42g and 42b through contacts a of switch 43 when it is desired to detect circumferential motion. Valve circuits. The 3/1 ring counter 40 comprises, Fig. 1a, three bi-stable trigger pairs 61a, 61b; 63a, 63b and 65a, 65b with the input pulses A, Fig. 3, applied directly from terminal 15a to the anodes of 61b, 63b and 65b, via diode 79 and capacitor 81 to the anode of 61a and via corresponding diodes and capacitors 73, 76, 75, 78 to the anodes of 63a and 65a, the cathodes of the diodes being so biased that only the diode interconnecting two adjacent cut-off valves, e.g. 61b and 63a, Fig. 2a, is conductive. Assuming the initial conditions of Fig. 2a, diodes 76 and 79 become successively conductive on receipt of the next two trigger pulses A, Fig. 3, and the resultant voltages at the anodes of 61a, 63a and 65a which are connected to output terminals 41r, 41g and 41b, vary as shown by curves B, C and D, Fig. 3.

Filed: 1957-07-08
Abstract: 854,202. Electrolytic etching. MORLE, C. W. (Philco Corporation). July 8, 1957, No. 21526/57. Class 41 A method of treating a body 10 of semiconductive material, e.g. a germanium wafer, with a liquid, e.g. a solution of an electrolyte, comprises forming a drop 18 of the liquid with one surface of the drop exposed to atmosphere and the other contacting the body 10, feeding liquid to the inner part of the drop, and maintaining a gaseous current around the drop 18 in such a manner as to propel liquid of the exposed surface away from the body surface 10. The liquid may be an aqueous solution of sodium nitrate, sodium chloride, sodium sulphate, potassium nitrate, or nitric acid. A pump 17 delivers the electrolyte solution 14 through a flexible conduit 16 to an inner nozzle 12 having a central tube 32 from which the solution issues to contact the wafer 10, either in the form of a drop 18 or as a self-supporting jet. A vacuum pump 20 applies suction through conduits 21, 23 to an outer co-axial nozzle 13, whereby solution, after contacting the wafer 10, is withdrawn through the nozzle 13 and passed by the conduit 23 to a closed reservoir 22. An electrode 30, e.g. of stainless steel, supplies current to the solution, the wafer 10 being suitably connected in circuit as indicated. A gas trap 31 is provided above the electrode 30. In operation, the rate of the pumps 17, 20 is adjusted to give a bubble at the outlet of the tube 32, liquid being continuously supplied to and taken from the bubble, and the wafer 10 contacted by the bubble, e.g. by accelerating the pump 17 or by pinching the tube 16, e.g. through a relay-operated device 40. The liquid then spreads outwardly over the surface of the wafer 10 to take up a stable position. Electrolysing current is passed, e.g. for up to 20 seconds, and the etching promoted by the application of light. The thickness of the etched portion of the wafer 10 may be measured electronically e.g. by a thin wire sensing electrode 37 connected to a circuit unit 39. Electroplating may be initiated by reversing the polarity of the electrolysing circuit. In a modification, the electrolyte contacts the wafer 10 in the shape of a jet which spreads out on contacting the wafer, the constructional details of the apparatus being as described above, except for the omission of the device 40. Reference has been directed by the. Comptroller to Specification 805,291.
