Patent GB-909459-A (GB)
Title: Shaped metallic bodies
IPC: C25B11/04
Filed: 1959-02-25
Abstract: A composite metallic member comprises a metallic base coated with a double skeleton catalyst layer consisting of 99 to 5% of a porous electronically conducting supporting catalyst and 1-95% of a Raney metal, the coating being bonded to the base by sintering and then etched by an alkaline or acid solution so that Raney metal particles remain embedded in the supporting skeleton.  The metal base which may be solid or porous and the supporting skeleton consist of one or more metals from Groups I to VIII of the Periodic Table and/or an alloy of one or more of these metals and the Raney metal is a metal of one of these groups with optionally up to 50% by weight of an activating agent such as Cu, Pd, Pt, Al2O3, ZnO or LiO for Raney Ni, Cr, Mn, V, Nb, Pt, OS or MnO2 for Raney Ag, Ni or NiO for Raney Cu, and Cu, Ni, W or WC for Raney Mo.  The powdered coating materials are applied to the roughened metal base by cold pressing or rolling and sintering above 400 DEG C., preferably at 600 DEG -1100 DEG  C. in a hydrogen atmosphere, or by hot pressing or rolling at 400 DEG -600 DEG  C.  A volatile material such as citric acid, oxalic acid or ammonium carbonate may be added as a pore former and the supporting skeleton material may be applied to the base and sintered separately prior to applying the Raney alloy, or the powdered mixture of the skeleton and the Raney alloy may be applied together.  The skeleton material particle size should be between 1 to 200 micron and the Raney alloy particles size should be less than half the pore diameter of the supporting skeleton. Alternatively the porous supporting skeleton may be formed by either of the following methods: (a) etching the base with acid or alkali; (b) oxidizing and then reducing the surface of the metal base; (c) galvanic erosion of the metal base; (d) treating the metal surface with carbon monoxide; (e) by electrolytic deposition.  In the examples the soluble component of the Raney alloy is Al and the alloy compositions are Ni/Al 50 : 50 and Ag/Al 65 : 35, although zinc and magnesium may also form the soluble constituent of the Raney alloy.  Specifications 907,907 and 908,436 are referred to.

Title: Method of producing an electrochemical reaction between the gases of a gas mixture bymeans of glow discharges
IPC: B01J19/08
Filed: 1931-03-03
Abstract: Reactions between gases are carried out by submitting the gases to the influence of positive glow discharges emitted by one or more discharge electrodes coacting with one or more electrodes which are earthed or of opposite polarity.  Liquid or solid products will be electrically precipitated by the field in which the reaction occurs, and any unprecipitated products may be separated by a subsequent electrical field.  The reaction may be assisted by the addition of electrically charged particles or other carriers of electricity before or during the treatment with glow discharges.

Title: Improvements in or relating to boot or shoe lasting machines
IPC: A43D21/02
Filed: 1922-03-10
Abstract: 198,784. British United Shoe Machinery Co., Ltd., (United Shoe Machinery Corporation). March 10, 1922. Lasting and pulling over.-In a step-by-step lasting machine of the kind described in Specification 14453/97, fastening means co-operate with shoe-positioning means to obtain that one fastening holds the upper by passing through it and a lip on the sole and another fastening holds the upper by passing through and into the body of the sole. At each lasting step, the overdrawn and wiped-over upper edge may be secured by a staple driven substantially parallel to the sole through the sole lip, and also by a tack on each side of the staple and substantially perpendicular to the sole; or one or two of these fastenings may be' omitted. Further, the tacks may be only partially driven, to facilitate their withdrawal when the upper has set. A main fastenercarrying and wiping slide 16, Fig. 5, is reciprocated by a pin 104 on the slide, the pin carrying a lever one arm of which has a roll 110 engaged by a cam on the main shaft and the other arm has a pin 112 sliding in a slot 113, the inclination of which varies the movement of the slide 16 according to the distance of the lip from the edge of the sole. To effect this variation the slot 113 is formed in a block 99 pivoted to the frame and urged by a spring 106 to a position determined by a measuring rod 94, the forward end of which engages a lever connected to the lip support. The support is locked to take the thrust of the staple-inserting drive by teeth 118 operated by an arm 121 pressed in one direction by a spring and in the other by a cam 125. The staple forming means are slid along guides in the slide 16 by a segment 27 and comprise a cutter 22, Fig. 10 and formers 21 which bend the cut length round an anvil 34 and then engage a table 24 but are afterwards lifted to enable a driver to force the staple through an opening 48 above the wiper 115. The front of the slide 16 also carries two pairs of tack sustaining springs 150. Above the tack carrying openings 146 a tack separator 130, Fig. 5, is reciprocated yieldingly in both directions. When it is not desired to drive tacks, reciprocation of the separator is prevented by an arm 166 on a shaft 164 also actuating at its upper end a pair of members 159, Fig. 3, which when swung under the usual buffer on the driver bar prevent its descent. The members 159 may be of less depth to allow tacks to be partially driven. The shaft 164 is operated by connections from a handle 177 also operating connections to a pawl actuating the wire feeding rolls, so that when the handle is fullv raised no tacks are driven, and when the handle is fully depressed no staples are driven.

Title: Improvements in or relating to the production of ready-to-eat, puffed cereal products
Inventor: CLAUSI ADOLPH SCOTT
IPC: A23L1/18
Filed: 1959-03-02
Abstract: The production of a puffed, ready-to-eat cereal product involves drying small shapes of an uncooked cereal e.g. maize, wheat, rice or oat, dough to a moisture content of below 16% by heating, the time and temperature of drying being so correlated that the starch granules of material, viewed microscopically under polarized light, show a substantial loss of Maltese crosses, but retain their shape and are largely unruptured, and gun-puffing the dried dough shapes to pieces several times larger than, but of the same configuration as, the original dried pieces.  The moist dough may contain 5-50% of pregelatinized farinaceous material, e.g. pregelatinized maize, oxidized maize, waxy maize, tapioca or potato starch.  The dough may have 20-50% moisture content. Drying of the shapes before puffing may be at 250-400 DEG F. to 3-16% moisture content.  Sugar, salt, malt, vanilla, defatted soya bean, wheat germ, wheat gluten or dried skim milk may be incorporated. U.S.A. Specification 2,196,304 and 2,333,442 are referred to.

Title: Improvements in or relating to shock absorbers
IPC: F16F9/348
Filed: 1934-03-07
Abstract: 428,325. Valves. STEVENS, A. H., 5, Quality Court, Chancery Lane, London.- (Spicer Manufacturing Corporation; 4100, Bennett Road, Toledo, Ohio, U.S.A.) March 7, 1934, No. 7265. [Class 135] [See also Groups XXXII and XXVI] In a valve comprising relatively stationary and movable parts for permitting relatively free flow of fluid in one direction through the piston of a shock-ab. sorber while retarding flow in the other direction, the movable part consists of an apertured rigid member adapted to seat directly on the stationary valve part, and a flexible or spring - pressed movable member adapted to co-operate directly with the rigid member to close the aperture or apertures therein, the members being moved away as a unit from the stationary valve part for fluid flow in the free direction, while during retardation of fluid flow, the rigid member is seated against the stationary valve part and the movable member is moved away from the rigid member by fluid forced through the aperture or apertures of the latter. As shown in Fig. 4, the passages 26 in the piston 14 are controlled by a rigid disc 28 and a flexible disc 92 normally closing apertures 32 in the disc 28. In a modification, in order to compensate for changes in the viscosity of the fluid due to changes in temperature, the flexible disc is formed of metal sheets having unequal coefficients of expansion, so that with increase of temperature the disc is distorted so as to press more firmly against the rigid plate while with decrease of temperature the disc is distorted so as to press less firmly against the rigid plate. In another construction a spring washer 82, Fig. 8, presses a flanged sleeve-member 76 slidable on the piston-rod 68, against a rigid apertured member 75. On the downstroke of the piston 65 fluid flows through passages 72 therein, raises the members 75, 76 as one unit, and flows around the periphery of the member 75 to the upper part of the cylinder 67. On the upstroke, fluid flows through the apertures 79 in the member 75, and, when the pressure is sufficient, moves the member 76 away from the member 75 and escapes below the piston. In a modification, Fig. 10, the rigid member 96 is cup-shaped and screwed to a sleeve 99, a flexible plate 97 governing the flow of fluid on the upstroke of the piston 90.

Title: Process for the manufacture of salts of higher homologues of polyhydroxybenzenes
IPC: C07C39/235
Filed: 1929-03-06
Abstract: 330,519. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). March 6, 1929. Salts of phenols with metals and bases.-Aliphatic homologues of polyhydroxybenzenes in which the alkyl side chain contains at least eight carbon atoms, are converted by known methods into their metallic salts or into salt-like compounds with bases. When using bases, the products may contain other proportions than equimolecular proportions of the two components. The reaction may be effected by double decomposition of a metal salt of the phenol with a salt of the base. A solvent, such as alcohol and chloroform, may be present and heat may be applied. The products possess therapeutic properties. Examples are given of the interaction of (1) octylresorcinol, decylresorcinol, dodecylresorcinol, decylpyrocatechol and decyl pyrogallol with hexamethylenetetramine; (2) decylresorcinol with piperazine, sarcosine anhydride and betaine; (3) sodium decylresorcinolate with calcium chloride. Polyhydroxybenzenes.-Decylpyrocatechol and decylpyrogallol are prepared by reducing the ndecylyl derivatives of pyrocatechol and pyrogallol, which latter are obtained by treatment of the phenol with capric acid and zinc chloride. The Provisional Specification states that other homologous polyhydroxybenzenes are prepared by the known process for the manufacture of hexylresorcinol.
