Title: Improvements in or relating to the electrodeposition of gold
Inventor: MANNING PETER MICHAEL
IPC: C25D3/48
Filed: 1961-02-08
Abstract: 930,561. Electrodepositing gold. ENGELHARD INDUSTRIES Ltd. Feb. 7, 1962 [Feb. 8, 1961], No. 4728/61. Class 41. Gold is electrodeposited, e.g. on silver, nickel, copper, or an alloy thereof such as phosphorbronze, Cu-Be or Ni-Ag, from a solution containing 1 to 100 g./l. of KAu(CN) 2  and 5 to 500 g./l. each of (NH 4 ) 2 HPO 4  and KH 2 PO 4 , the pH value being adjusted to 4.0-6.5. The temperature of the solution may be from room temperature to 90‹ C., and the current density should preferably not exceed 20 amp./sq. ft. A platinum or platinum-coated titanium anode may be employed with a reciprocating cathode for agitating the solution which may be replenished by the addition of a gold compound such as KAu(CN) 2 , NaAu(CN) 2  or AuCN. The process is suitable for plating connectors of printed circuit boards. With base metals other than the above, suitable pretreatment may include applying an undercoat of Ag, Ni or Cu.

Abstract: 685,353. Fluid-pressure servomotor-control systems ; electrically actuated valves. RESEARCH CORPORATION. March 5, 1951 [April 26, 1950], No. 5254/51. Class 135 [Also in Group XXXV] In a servomotor system of the kind comprising a hydraulically actuated mechanism 14 controlled by a spring-loaded valve 26 which is actuated by the pressure in a chamber 31, which pressure is varied by movement of a member 34 controlling an outlet 36 from the chamber 31 in response to control signals applied to an electrical actuator 35, the actuator consists of a permanent magnet and an electro-magnet, and the force acting on the armature 34 due to the permanent magnet is balanced by a spring 51. Member 34 is a spring arm fixed at its upper end. The actuator may consist of a motor with a rotary armature. The electro-magnet shown may have simple or push-pull coils. A hydraulic pressure fluid is applied at 19 to the right-hand (smaller) face of piston 14, and it flows along passage 28 to the valve 26 and also past a restriction 40 to the chamber 31 and to outlet 36. Oscillation of valve 26 is prevented by providing a damping restriction 37 between chamber 31 and the outlet 36. In the neutral position of valve 26, to which it is urged by a leaf spring 23, there is negative lap between the controlling edges of the valve and the chamfered edges of the co-operating groove 25 so that there is a small flow of fluid from passage 28 through passage 29 to the left-hand side of piston 14 and also to an exhaust passage 30. Fluid which escapes from the outlet 36 flows to exhaust through a passage 43.

Filed: 1974-02-05
Abstract: 1452541 Acoustic devices ALLIED CHEMICAL CORP 5 Feb 1974 [5 Feb 1973] 5292/74 Heading H3U [Also in Division C7] An acoustic device, e.g. a delay line, comprises a metal alloy body which is at least 50% amorphous as measured by X-ray diffraction, the term "alloy" including mixtures of a metal with certain non-metals. The alloys used are of the general formula TiXj where T is one or more transition metals and X is one or more of aluminium, antimony, beryllium, boron, germanium, carbon, indium, phosphorus, silicon and tin and examples of preferred alloys are given. At high frequencies amorphous bodies have the advantage over polycrystalline bodies that the attenuation varies as f<SP>2</SP> rather than f<SP>4</SP>. The body may be in the form of a wire, which passes torsional waves, a strip, which passes shear waves, or be in bulk form, e.g. a rod. Piezoelectric or magnetostrictive transducers may be used. In the case of a wire, magnetostrictive delay line, a variable delay may be obtained by arranging for one of the transducers to be movable. Examples are given of methods of manufacture of acoustic devices according to the invention. A wire is produced by passing molten alloy through an orifice into brine solution at - 20‹ C. A strip is produced by passing molten alloy from a silica tube between rotating rolls at room temperature. A rod is produced by melting alloy in a silica tube and rapidly quenching it in brine solution at - 20‹ C.

Title: Improvements in, and in the Manufacture or Production of, the Tops of Cycle and like Saddles.
Inventor: JELLEY JAMES
IPC: B62J1/00
Filed: 1917-05-21
Abstract: 115,407. Jelley, J., and Jelley, H. May 21, 1917. Saddles.-Cycle and like saddle tops are made from composite or laminated material consisting of canvas or other fabric coated on both sides with rubber, the upper and under rubber layers being differently hardened by the vulcanizing treatment. The upper rubber layer may have such a proportion of vulcanizing-substance that vulcanization produces upon it a smooth and well finished surface. The mixing of the under layer, on the other hand, may be such that the heat treatment during the shaping or production of the top causes the under layer to be vulcanized to a harder degree than the upper layer. The hard under layer may be of uniform thickness: or it may be thicker in the middle than at the sides. The fabric layer or layers may also be of a coarse or open-woven character, so that part of the rubber of the outer layers may be forced into the fabric under the blocking pressure. The top may be strengthened by vulcanizing pieces of fabric to the underside with extra pieces at the peak and cantle parts. Specification 1059/15 is referred to.

Pressures suggested range from below 50 p.s.i.g. to 500 p.s.i.g.  Low cuprous content in the catalyst favours conversion to more highly chlorinated products.ALSO:A hydrocarbon chlorination catalyst comprises a liquid, homogeneous between 90 DEG and 200 DEG C and consisting substantially of water, copper chloride and additional chloride with 7 to 11 gm. atoms/litre of copper of which 10 to 90% is cuprous with the remainder cupric and the ratio of additional chloride in total gm. atoms to copper in total gm. atoms is 0.01 to 0.8 and less than 0.5 where the total gm. atoms of chloride/litre are above 15.  The additional chlorides are HCl, NH4Cl, alkali metal and/or alkaline earth metal chlorides.

Abstract: 252,089. Ross, T. W., Ryder, C., and Metropolitan-Vickers Electrical Co., Ltd. Feb. 28, 1925. Induction relays; springs, arrangement and disposition of.- An induction relay provided with a rotor disc biassed to one position is arranged so that the operating torque opposing this bias increases suddenly prior to the engagement of the contacts and decreases suddenly prior to their disengagement so producing a quick opening and closure of the contacts. The disc 10 has a cut-away portion one end of which is held by the biassing spring 16 against a fixed stop 28. On rotation of the disc due to energization of the operating electromagnets 12 the disc moves in an anticlockwise direction and after lost-motion has been taken up the pin 26 engages the pivoted contact-arm 17 which is normally held against a stop 22 by a dead-centre spring 19. At or just before this point in the motion of the disc in order to overcome the increased biassing force encountered while the contact is moved across the dead centre position the portion of the disc in the magnet gap is increased by thickening of the disc or increasing its diameter as at 24 so that the contact member 17 is moved beyond its midposition and engages its co-operating fixed contact 23 with a quick action. When the disc is restored to its initial position on reduction of the current in the coils 14, a second pin 30 after lost motion has been taken up engages the contact arm and the extension 24 of the disc is so arranged that it has left the magnet gap so reducing the torque opposing the spring 16 just before the contact arm is moved back across the dead-centre position. To prevent swinging or oscillation of the disc 10 a damping magnet 32 is provided.
