Title: Process and apparatus for producing shaped resistance-welded bimetallic articles
IPC: H01H11/04
Filed: 1962-07-31
Abstract: 1,014,826. Making bimetallic contacts; welding by pressure; shearing; forging. W. RENZ, H. WACKER, and E. SEITZ, [trading as RENZ, WACKER & CO.]. July 31, 1962 [July 31, 1961; May 16, 1962], No. 29393/62. Headings B3A, B3H, B3R and B3W. In making resistance welded shaped articles e.g. bimetallic contacts, from wires of different metals, the ends of two wire elements are buttwelded and the welded wire elements are supplied to a pressing device, a turntable having dies and pressing rods being employed. A turntable 1, Figs. 1, 2, carried in a toothed ring 2 co-operating with a locking pin 4 engaged after each indexing step of the table, has six parting- off dies 3 spaced around its periphery. At station I a copper wire 5 is fed through a stationary guide 6 into a die 3 and as the table is rotated to Station II an end of the wire is sheared. At Station II a silver wire is fed through a guide 8 into the die above the piece of copper wire and as the table is indexed to station III the end of the silver wire is sheared. The table is rotated to Station IV where the pieces of wire are resistance welded by a ram 9 connected to one side of a supply transformer 15 by cam-operated pick-up 14, the other side being connected to the turntable. The table is indexed to Station V where a ram 12 connected also to the transformer 15, finally shapes the welded body which is ejected as a bimetallic contact rivet from the die by a needle 13 at Station VI. A finished rivet is produced at each indexing movement of the table. In a modification using a similar turntable, a copper wire 5 is fed through a guide at Station I, Figs. 3, 6, to be sheared as the table indexes to Station II where a silver wire 7 is fed through a guide 17 into a chamber 18. The copper wire 5 is lifted by a needle 20 until it abuts the silver wire and is clamped by clamp 21. The pieces are resistance welded by current supplied from a transformer 24 under the control of cam-operated pick-up 14. The end of the silver wire is pushed into the die and as the table indexes, is sheared. At station IV the rivet head is shaped by a tool 28 and at Station V a finish pressing foot 29 provides the final shape on the rivet which latter is ejected at Station VI by a needle 30. In a further modification the wires are butt welded in guides outside the turntable, the welded ends are parted from the stock by a knife moving transversely between the guides and are supplied to a die in the turntable which brings them beneath the pressing rods.

Filed: 1919-11-28
Abstract: 164,038. Evans, L. T. Godfrey-, and Evans, J. Godfrey-. Nov. 28, 1919. Regulating.-The engine is governed by controlling the supply of liquid fuel to a carburettor in accordance with the pressure, or a range of pressures, in the working cylinder during a part of the working stroke, a loaded valve 4, 4<1> being arranged to pass a volume of gas determined by such pressure so as to displace, at every working stroke, a corresponding volume of liquid fuel from a tank 1 connected to the carburettor. As shown, a pipe 5 containing a non-return valve. connects the working cylinder with a chamber 8 containing a differential piston valve 4, 4<1>. The position of the valve is determined by a spring 6 and by the pressure transmitted through the pipe 5, and the valve overruns a passage 9 through which varying volumes of gas pass to the fuel tank at each stroke of the working piston. The valve may have an oil dash-pot 11. In the ordinary operation of the engine, the normal position of the valve is with the lower edge of the piston 4 nearly coinciding with the lower edge of the port 9. When the load on the engine is suddenly thrown off, the pressure in the middle chamber is relieved through a by-pass 9' and a vent 10'.

Title: Improvements in or relating to methods of manufacturing semi-conductor devices
IPC: H01L21/00
Filed: 1959-09-02
Abstract: 914,262. Semi-conductor devices. PHILIPS ELECTRICAL INDUSTRIES Ltd. Sept. 2, 1959 [Sept. 5, 1958], No. 29958/59. Class 37. A method of making a semi-conductor device comprises heating a body of germanium at above 150 C. in an oxidizing atmosphere and subsequently alloying a material containing a significant impurity to the body. At least part of the alloying process is carried out in the presence of a flux capable of reacting with either the germanium or the significant impurity containing material to form a halide. In an embodiment an N-type germanium wafer after heating in air at 200 C. for 10 minutes or at 500 C. for 5 minutes is placed in the jig shown with an indium pellet and the assembly heated at 300 C. for a few seconds in dry hydrogen containing a trace of hydrochloric acid gas. The jig assembly is then inverted and a second indium pellet placed in the uppermost cavity. After heating as above to enable the pellet to wet the wafer and to tin solder a base contact to the wafer the temperature is raised to 600 C. to complete the alloying of the indium with the germanium to form opposed PN junctions. Other halogen hydrides, complexes of hydrogen halides and organic molecules, e.g. pyridine hydrochloride, and some inorganic halides, e.g. indium chloride, are also suitable as fluxes.

IPC: G21C21/02
Filed: 1964-07-29
Abstract: 1,055,076. Fuel elements. INTERNATIONAL RESEARCH & DEVELOPMENT CO. Ltd. June 15, 1965 [July 29. 19641. No. 30130/64. Heading G6C. A fuel element comprises a solid fuel member disposed in a container with the surface of the fuel member spaced from the container by a thermally-conducting layer of compacted powdered material. Particular reference is made to elements having layers of compacted magnesium and beryllium, but the invention also includes elements having compacted powder layers of other metal combinations, of single metals such as niobium, of non-metals or of metals and non-metals. Preferably, the fuel member is first placed in the container and the space between them is filled with the powdered material. The container is an open-ended cylinder which has one end plugged before the filling takes place. The filling is carried out under vacuum whilst the container is vibrated. When the space between the fuel rod and the container has been filled, the other end of the container is plugged. The container is then subjected to mechanical swaging to compact partially the powdered material. This is followed by compression of the container by explosive forces to complete the compaction of the powdered layer. The container is placed concentrically within a cardboard cylinder on the outer surface of which a thread-like explosive material is wound spirally. The assembly is placed in a water bath and on detonation of the explosive material a compressive force is transmitted through the water to the container.

Title: Process for the manufacture of hydroxydiphenylene compounds
Filed: 1933-11-01
Abstract: Trinuclear hydroxydiphenylene compounds, i.e. hydroxy derivatives of compounds containing two phenylene nuclei united by a five-membered ring or by a six-membered heterocyclic ring, are prepared by heating the corresponding halogen derivatives with a hydroxide of an alkali or alkaline earth metal.  Hydroxy derivatives of diphenylene-oxide, -sulphide, -sulphoxide, -disulphide, -ether sulphide, and -dioxide, and of thianthrene, may be so prepared.  The reaction may be effected in the presence of copper or a copper compound as a catalyst.  In the examples, (1) 3-bromodiphenylene oxide is heated with aqueous caustic soda to yield 3 - hydroxydiphenylene oxide; 3 - chlorodiphenylene oxide, prepared analogously to the known 3-bromo compound, may also be used as starting material; 2-hydroxydiphenylene oxide is obtainable similarly from the 2-bromo compound; (2) 3-bromodiphenylene sulphide, obtained by brominating diphenylene sulphide, is heated with aqueous strontium hydroxide in the presence of copper bronze to yield 3-hydroxy-diphenylene sulphide; (3) 3-bromodiphenylene sulphone, obtainable by oxidizing 3-bromodiphenylene sulphide with hydrogen peroxide, is heated with aqueous barium hydroxide in the presence of copper oxide to yield 3-hydroxydiphenylene sulphone; (4) 2-bromothianthrene, obtained analogously to the known monochlorothianthrene, is heated with aqueous calcium hydroxide in the presence of copper oxide to yield 2-hydroxythianthrene.  The Specification as open to inspection under Sect. 91 states that the process may be applied to the manufacture of hydroxycarbazoles, and includes the following examples: (1) 3-bromocarbazole is heated with aqueous caustic soda in the presence of copper powder to yield 3-hydroxycarbazole; 2-chlorocarbazole similarly yields 2-hydroxycarbazole; (2) 9-acetyl-3-bromocarbazole is treated as in example 3 above to yield 3-hydroxycarbazole.  The Specification refers also to the production of 1-hydroxydiphenylene oxide from 1-chlorodiphenylene oxide, which is prepared by diazotizing 2-amino-2<1>-chlorodiphenyl ether and boiling the diazo compound with aqueous sulphuric acid.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to wipers for windscreens and other surfaces
IPC: B60S1/44
Filed: 1935-11-04
Abstract: 465,350. Cleaners for windscreens &c. WILKINS, C. T., and DE HAVILLAND AIRCRAFT CO., Ltd. Nov. 4, 1935, No. 30424. [Class 138 (i)] A wiper for windscreens and other surfaces comprises a rotor carrying or serving to actuate wiper elements contacting with the surface to be wiped, the rotor carrying pivoted flaps or vanes constructed to be capable of movement, when subjected to an air flow directed simultaneously on and transversely to the vanes on both sides of the axis of rotation of the rotor, into positions relatively to the rotor in which those vanes situated on opposite sides of the axis afford different resistances to the air flow. In the construction shown in Figs. 1 and 2, a hollow boss 11 secured to a windscreen 10 carries a rotor comprising a rotatable spindle 18 to which is secured a rod forming arms 15, 16. Each arm is provided with a rubber wiping strip 23 and a pivotallymounted vane 27 which is shaped so that its rotary movement about its axis 26 is limited by the arm 15 or 16. Air flow passing upwardly of the screen causes the rotor to move in the direction indicated by the arrow 28, the vanes taking up the positions indicated. The vanes change their positions as the rotor rotates. In a modification indicated in Fig. 3, the rods 15, 16 are connected to the spindle 18 through a resilient strip and the axes of the rods are each provided with a loading element 29, so that as the speed of the rotor increases centrifugal force acts to press the wiping blades against the screen, thereby preventing excessive speed. In a modification the rods have a hinged or equivalent connection with the spindle 18 permitting limited movement of the rods towards and away from the screen. In a further arrangement indicated in Figs. 4 and 5a, the spindle carrying the rods 15, 16 is rotatably mounted in ball bearings on one end of an arm 30. The other end has a projection 40, which is engaged in a sleeve 41 and is provided with a handle 42, by means of which the arm 30 may be moved from the position shown to a position where the wiper is inoperative and clear of the screen. The arm is held in either position by means of a cross-pin 46 on a reduced portion of the projection 40, the cross - pin co-operating with slots on the sleeve 41 under the influence of a spring 43. According to the Provisional Specification, the rotor arms may have flat vanes inclined with respect to the surface of the screen, the lower edge of each screen carrying a wiper element. In a further modification, the vanes are curved longitudinally in planes parallel to the screen. In a still further modification, the arms are provided with hollow cups each carrying a wiping element.
