Patent GB-833294-A (GB)
Title: Method and apparatus for making and determining the quality of resistance welded joints
IPC: B23K11/25
Filed: 1957-09-12
Abstract: 833,294. Electric indicating systems. SCIAKY, D. Sept. 12, 1957 [Nov. 8, 1956], No. 28755/57. Class 40 (1). [Also in Group XXII] In making and determining the quality of resistance welded joints wherein a workpiece is clamped between fixed and movable electrodes, deflection of electrical strain gauges is produced by the upward movement of the movable electrode caused by expansion of the welded joint which takes place during flow of current, an output voltage proportional to the deflection is produced and this voltage is used to energize at least one indicator depending on the magnitude of the voltage. Movement of the electrode deflects a cantilever beam carrying compression strain gauges on its upper side and tension strain gauges on its under side. These gauges are connected in a bridge whose output may actuate a galvanometer or a recording oscillograph. Alternatively, the bridge is connected to a voltage amplifier 118, Fig. 6, whose output feeds the grid-cathode circuits of gas-filled thyratron tubes 120, 121 whose plates are connected to a low limit relay 132 and a high limit relay 141 in circuit with a normally closed contactor 133 and a battery 134. An output of minimum value will trigger the tube 120 to energize relay 132 and a maximum value output will trigger the tube 121 to energize relay 141. These relays operate switches in a lamp circuit, Fig. 7. If the output voltage is too low it will not energize relay 132 so that lamp 143 lights indicating a bad weld. If the voltage is above the low limit but below the high limit, the relay 132 is energized to open its switch 146 and close switch 152 so that lamp 147 lights indicating a good weld. If the voltage is above the high limit, relay 132 and relay 141 are energized to open contacts 146 and 151 and close contacts 152 and 156 so that lamp 153 lights indicating a bad weld. Bells or other indicators may replace the lamps. Specifications 811,338 and 833,295 are referred to.

Filed: 1945-11-02
Abstract: 602,289. Projectile fuzes. TAYLOR, G. Nov. 2, 1945, No. 29141. [Class 9 (i)] [Also in Group XXXVII] The striking pin 7 of a bomb fuze is moved axially by a spring 11 under the control of a friction brake acting on a nut 18 rotated by a screw thread 19 on the pin. The brake comprises friction rings 17 between which the nut 18 is gripped, and which are subject to the pressure of a spring 21. The pin is normally held released by a nut 6 which is screwed off the pin as the bomb falls by air vanes attached to a yoke 6 on the nut. A shutter 25 pivoted on a pin 26 normally closes an aperture 24a through which the striker passes to strike the detonator. On impact the shutter is first moved vertically on its pivot to clear the head of a holding screw and is then swung by a spring 27 to bring an initial detonator contained in a cup in the shutter, beneath the striker. A safety washer 22 prevents inadvertent release of the pin 7. In release position, to relieve the load on the friction rings 17, the end of the thread 19 bears against the top of a flanged member 21a which supports the spring away from the friction rings.

Abstract: 445,480. Lace machines. JARDINE, Ltd., J., 26, Deering Street, and MONTGOMERY, H., 1, Sophie Road, both in Nottingham. Oct. 12, 1934, No. 29197. [Class 74 (i)] This invention refers to a twist lace machine and particularly to an improved automatic magazine feed device for supplying bobbin thread continuously of the kind set forth in Specification 18909/12, [Class 74 (i)]. Carriages 10 with full yarn supply from a magazine 9 are fed one by one by an oscillating and reciprocating arm 16, the free end 18 of which engages the endmost carriage and feeds it between plates 19 forming a part of the carriage track. The carriages in the magazine 9 are urged towards the feed-end thereof by a loaded ratchet device. A transfer device 20, rockable about an axis 22, receives each carriage from the track 19 and turns about its axis so that an oscillating arm 25 provided with lugs 26 may remove it therefrom and feed it forwardly into spaced leading-in combs 8 and thence to the movable end carriage gate 2. This latter is then moved inwardly towards the machine so that the turn-again pinion 1 moves it into the combs on the front comb bar 7, A carriage with yarn almost exhausted is, at the same time, delivered from the rear comb-bar 3 by the arm 25 to the carriage transfer device 43 which, in oscillating about its pivot 49, positions the carriage to be further delivered by an oscillating arm 45 through the track plates 44 to a rear magazine 42 where an oscillating abutment 47 presses the carriage into the magazine where it is retained by spring catches. During the feeding inwardly of the carriage with full yarn supply, the end of the yarn is gripped by cam and spring- operated jaws 35 and held while it is connected up to the work. Before the removed carriage reaches the rear magazine 42 the thread therein is severed by an oscillating knife 52.

Title: Plane concentric field-effect transistor and method of manufacturing the same
IPC: H01L29/00
Filed: 1959-08-27
Abstract: 899,858. Semi-conductor devices. FRANKE, J. I. Aug. 27, 1959 [Aug. 29, 1958], No. 29298/59. Class 37. A field effect transistor has three contiguous plate-type regions, the first of one type of conductivity, the second of the opposite, and the third of the same type but with heavier doping than the second, the gate electrode being constituted by a circular ring situated in a ditch in the third layer and having a rectifying contact both with the third region and the second region along the bottom of the ditch. The Specification explains that the formation of the ditch by electrolytic etching is assisted by the three-layer arrangement because the difference in speed between etching of the low resistance third layer and the high resistance second indicates when the bottom of the third layer has been reached;, the depth of the ditch is uniform because the etching is practically stopped when the second layer is reached and the width of the bottom of the ditch can be known with great accuracy because of the variation of resistance with depth of the third layer. A field effect transistor according to the invention is shown in Fig. 3 and consists of a circular base-plate 22 of P-type germanium, the thin part 21 of which has been doped into N-type. A deposit 27 of N+type is arranged by diffusion on the outer side of plate 21. The circular ditch 23 is hollowed out by electrolytic etching in the N+ layer, the bottom of the ditch being constituted by the surface of the junction between layers 21, 27. The ditch is formed by protecting the surface of the transistor before etching with a varnish through which a circular line is scribed with a sapphire stylus. In the ditch a ring 24 of indium is deposited which coats the gate of the field effect transistor. Drain electrode 26 is made by a deposit of N+ germanium still more strongly doped than part 27. Annular electrode 25 is also more strongly doped than part 27 and constitutes the source electrode. Specification 812,554 is referred to.

Title: An improved method of separating waxy constituents from oils
IPC: C10G73/06
Filed: 1934-10-13
Abstract: Hydrocarbon oils are dewaxed by adding wax tailings to the diluted oil and then chilling and separating the wax.  Wax tailings consist of the final distillate, solid at ordinary temperatures, obtained from a wax containing oil.  The wax tailings may be submitted to a mild oxidation treatment with air at ordinary or elevated temperatures before use.  A wax containing lubricating fraction is diluted with naphtha and mixed with 1,5 to 3,5 per cent or wax tailings, and after chilling to 0 DEG  F., the precipitated wax is separated by sedimentation, filtration or by centrifuge.  Naphtha may be replaced by other diluents such as liquefied normally gaseous hydrocarbons, benzol, toluol, xylol, or oxygen-containing organic solvents including lower alcohols, esters, ketones, aldehydes and acids or mixtures of these with naphtha, aromatic hydrocarbons or chlorinated hydrocarbons such as carbon tetrachloride or trichlorethylene. Suitable mixtures of diluents are (1) Butyl alcohol, naphtha; (2) amyl alcohol, butyl acetate; (3) diacetone alcohol, toluol; (4) Mesityl oxide, toluol; (5) ethyl carbonate, amyl acetate; (6) ethylene dichloride, butyl acetage; and (7) methyl ethyl ketone, toluol.
