Title: Improvements in or relating to the preparation of noble-metal layers
IPC: H05K3/10
Filed: 1960-07-22
Abstract: In a method of producing a noble metal layer on a non-metallic, electrically conductive, hydrophilic or at least superficially hydrophilized support in which the support is activated by successive treatment with an aqueous solution of an agent capable of reacting with a mercurous compound in the presence of moisture to liberate mercury and with an aqueous solution of a mercurous compound, in that order or in reverse order, and the activated surface then treated with a solution of a noble metal compound in the presence of a reducing agent for said compound to produce a noble metal layer, the mercurous compound solution also contains a silver compound and/or the noble metal compound solution contains an ionic surface-active compound with or without a non-ionic surface-active compound.  The support may be of gelatin, regenerated cellulose, paper, wood, polyvinyl alcohol, chlorosulphonic-acid-treated polystyrene and polyacrylate, saponified cellulose esters, polyvinyl acetate and polyvinyl chloride, and silica-gel-coated glass.  Mercury may be liberated by the action on mercurous nitrate (optionally with silver nitrate) of sodium carbonate, thiosulphate or sulphite, potassium thiocyanate, potassium cyanide, thiourea, allyl thiourea, sodium nitrite, potassium iodide, or stannous borofluoride. The noble metal layer may be deposited from solutions containing silver nitrate together with such ingredients as citric acid and lactic acid, and hydroquinone and pyrogallol.  The surface active compounds are exemplified by various proprietary products.  The layer, which may be continuous or a pattern, e.g. for a printed circuit or a radio station-name dial, may be after-treated, e.g. by over-coating. Specification 953,432 is referred to.

Abstract: 134,215. American Fork & Hoe Co., (Assignees of Lowell, E. D.). Oct. 21, 1918, [Convention date]. D-handles for agricultural tools of the type comprising a metal socket and arms of channel section with a wood hand-grip fixed between their ends, have the flanges of the arms gradually reduced in depth from the socket. to the grip, and the arms may also be gradually reduced in width. As shown, the socket 10, which is fixed to the end of the handle h, has integral arms 11 of channel section formed by edge flanges 12 and substantially flat central portions, as shown in Figs. 5 and 6. These flanges are gradually reduced and disappear at the ends of the arms, the ends being concave and riveted to the ends of the wood grip 20 by a through-rivet 30. The end of the rivet may be square, as shown at 32, to assist in preventing rotation of the grip. Two rivets 50, 51 at right-angles secure the socket 10 to the handle h. The device may be made from sheet metal, the edges being welded together at the socket 10.

Abstract: Trans-dec-2-en-9-one-1-acid is prepared by reacting glutaric dialdehyde with a triphenyl phosphoric carboalkoxy-methylene to give a hept-2-en-7-al-1-acid alkyl ester which is condensed with acetone in the presence of piperidine, piperidine acetate, an alkali metal or alkaline earth metal hydroxide or ammonium acetate to give a deca-2,7-dien-9-one-1-acid alkyl ester and the activated D 7-double bond of this molecule is partially hydrogenated with a lead- or quino-line-poisoned palladium catalyst to give the alkyl ester. Cis-components present may be isomerized with an iodine catalyst to the trans-ester which is hydrolysed with 2N sodium carbonate solution to the acid (MP 52-54 DEG C.).

Abstract: 1,125,702. Moulding wall panels. HIGH SPEED SYSTEM BUILDING Ltd., and L. NAAR. 17 Sept., 1965 [23 June, 1964], No.25936/64. Heading B5A. In a method of casting wall panels of brick and mortar in a horizontal grid, the grid frame 54 is carried by a bogie 55 on rails 11 over a trench 12 and is located in position by a framework upstanding from the trench and including plates 52 located slightly above the grid upper surface. When the mortar has set, a vertically reciprocable horizontal platform 19 with upstanding members 32 is raised so that the members pass through the grid, engage the bricks and lift the panel slightly until it strikes the plates 52, thereby breaking any bonds which may have formed between the panel and grid. After lowering the platform the grid and loosened panel are taken to means whereby the panel is finally removed, e.g. as described in Application 26014/64. The platform is raised and lowered by two pairs of toggle levers 22 pivoted to the platform and to nuts 18 engaging threads on bars 17 carried in blocks 16. Rotation of the bars by an electric motor in one direction or the other causes the nuts to run along the bars either towards or away from their centres to thereby lift or lower the platform. The upper end of each member 32 carries a buffer 44, Fig. 4, (not shown), carried by a tubular part 42 urged upwardly from a fixed part 37 of the member by a spring 49. The grids may be as described in Specification 1,093,192.

The machine comprises a rotatable frame having a top plate a. Figs. 1 and 4, and a bottom plate b connected by guide rods c, arranged in four pairs. The frame is rotated by a hollow shaft d arranged within a central pillar 8. Arranged upon each pair of guide rods are three receptacle holders on supports m, 13, 34. During the first stage of the filling, tea, &c. is delivered from an annular supply hopper g, Fig. 4, into one of a series of feed hoppers e from which it falls through a shoot f into a bag upon a vertical tube h containing a feed worm i. The latter is rotated by a pinion j engaging a toothed wheel k on a spindle l arranged within the hollow shaft d and rotated in an opposite direction thereto. Each holder comprises a pair of side pieces n and a base o pivoted on the support m and adapted to be opened and closed at the appropriate times by cams z, t acting upon slides w, q. The holder is vertically movable on the rods c by the action of a cam 3 on a roller 4. In use, a bag is placed on the tube h before arrival at the position shown in Figs. 1 and 4, and on arrival, the tea &c. is delivered and is forced into the bag by the worm i. the holder being lowered by the cam 3 so) that the worm relatively rises out of the bag. At the halfway position, the cam t swings aside the bottom o of the holder and the sides n are opened sufficiently to release the packet and to allow it to fall between swinging sides 14 and upon the base of a second holder immediately below.

Filed: 1924-11-05
Abstract: 224,534. British Thomson-Houston Co., Ltd., (Assignees of Howe, G. H.). Nov. 6,1923, [Convention date]. Metal pipes and tubes.- Metallic articles having a surface alloy of another metal to protect them against oxidation at high temperatures are provided with a core of another metal, the diffusion of this metal outward checking the diffusion inward of the alloving metal on the surface of the articles when the latter are heated. As applied to metal tubes, a composite tube is formed by inner and outer tubes 10, 11 of oxidizable metal such as iron or steel between which is fitted a core or tube 12 of aluminium. The inner and outer surfaces of this tube are now treated so as to cause aluminium or other suitable metal to alloy with these surfaces as at 19, 20. When this tube is exposed to high temperatures, the alloys in the parts 19, 20 will diffuse inwards into the parts 10, 11 meeting the diffusion of the core 12 outwards, the latter then checking the diffusion from the parts 19, 20. The tubes 10, 11 may be united by fitting a ring 13 into the space left by the shortened tube 12 and secured therein by a welded joint 14. When used as pyrometer tubes one or both ends of the tube may be closed by a composite cap formed by an inner cap 15 fitted between the tubes 10, 11 similarly to the ring 13, an outer cap 16 and a sheet 17 of aluminium between the parts 15, 16.
