Abstract: 1,125,643. Bearings. SEALOL Inc. 18 April, 1966 [1 July, 1965], No. 16938/66. Heading F2A. In a fluid bearing for supporting radial and thrust loads, a housing 11, Fig. 2, is bored to receive a shaft 50, a conical member 70 mounted on the shaft and a ring 41. The housing 11 is provided with a cone-shaped bearing surface 25 which receives, with clearance, a conical head 51 of the shaft 50; a bore 24 which receives, with clearance, the cylindrical portion of the shaft 50 ; and stepped bores 13, 15 which slidingly receive the ring 41. The ring 41 is provided with a cone-shap ed face 47 and the conical member 70 is adjustable on the shaft 50, a setscrew 77 being provided to look the conical member 70 to the shaft 50. Steps 64 and 74 on the conical head 51 and on the conical member 70 respectively act as restrictors and may be roughened so as to allow the passage of pressurized fluid when the clearance is a minimum. Seals 48, 72 are provided for the members 41 and 70, respectively, and the housing 11 is mounted on a base 12. In use, pressurized fluid is supplied through a port 16 to an annular chamber 100 and passes through the clearances and restrictors between the cone-shaped face 25 of the housing 11 and the conical head 51 of the shaft 50 and also between the cone-shaped face 47 of the ring 41 and the conical member 70. In modifications, a housing 11A, Fig. 5, has a stepped bore 13A which receives a cylindrical member 70A, the ring 41 being omitted; and a ring 41B, Fig. 6, acts as a piston and is provided with passages 131 therein which convey pressurized fluid from an inlet 26B to a clearance between said ring 41B and a conical member 70B. 1,125,644. Valves. CHICAGO PNEUMATIC TOOL CO. 3 May, 1966 [24 June, 1965, No. 19464/66. Heading F2V. A valve unit for a reciprocating air compressor comprises a seat member 15 having a pair 29, 30 of concentrically arranged air intake channels, a pair of concentrically disposed ring plate valves 36, 37, a keeper member 16 having an annular recess 27 to allow opening movement of the valves relative to the channels, a plurality of wells formed in the annular recess and a separate guide bore 42 coaxial with each well formed in the seat member, a valve guide member 38 associated with each well and abutting the undersurface portions of both valves, and a spring 43 seated in each well pressing upwardly against the underside of the valve guide member which is forcefully movable into its corresponding well upon opening of the valves. The guide is a one-piece structure made from plastic material with a glass filler to increase rigidity while the plate valves are of hardened stainless steel and are held on their seats by springs which are just strong enough to keep the valves closed when the compressor is at rest.

Title: Glass-ceramic article and method
IPC: C03C10/00
Filed: 1965-04-26
Abstract: A strengthened glass-ceramic article has an inner portion containing a parent crystal phase and an outer portion compressively stressed with respect to the inner portion, having a different crystal phase formed in situ having a lower coefficient of thermal expansion than the parent crystal phase.  The parent phase may be MgO-Al2O3-SiO2 containing an exchangeable Mg ion; nepheline containing an exchangeable Na ion or b -quartz containing an exchangeable Mg ion. The glass-ceramic article is contacted with Li+ -containing material to effect exchange of Li+ with an ion within the surface layer of the article, at 450-1050 DEG  C.  The Li+ -containing material may be a molten bath of Li salts with Na or K salts.  A further ion exchange-step may be performed by exposing the Li+ -treated article surface to material containing ions larger than Li+, e.g. a molten salt bath containing Na+ or K+. Heat-treatment schedules for devitrifying the original shaped glass bodies are exemplified.

Title: Improvements relating to the extraction of gas from solid fuel

IPC: C10B49/08
Filed: 1958-08-26
Abstract: 902,625. Making gas from solid fuel. STEINMULLER G.m.b.H., L. & C., and STEINKOHLEN-ELEKTRIZITAT-A.G. Aug. 26, 1958, No. 17499/62. Divided out of 902,624. Class 55 (1). In a process for extracting gas from solid fuel, finely-ground fuel and an oxidizing agent, together with a carrier gas, are supplied to a first reaction zone in a chamber, heat being supplied to the zone from a suspension of hot solid particles in a gaseous medium without the chamber such that surface oxidation of the particles of solid fuel is effected, whence the oxidized fuel is constrained to flow into a second reaction zone in which degasification of the fuel takes place. Preferably the solid particles are introduced into the gaseous medium in such a manner as to form eddy currents in the gaseous medium. The solid particles which may consist of ceramic materials, sand or coke, are preferably heated to above 1000‹ C. before they are mixed with the gaseous medium. When the solid particles consist of coke, they may, after surrendering their heat to the first reacting zone, be passed to a boiler for complete combustion. Additionally heat may be supplied to a part of the second reaction zone from a fluidized bed of hot, solid particles without the chamber, the bed being held in a fluidized state by a gaseous medium flowing through the bed from below. In an embodiment a gasification process working on the turbulent-layer system is combined with the gas extraction in such a manner that the turbulent layer surrounds the point in the gasification chamber in which the surface reaction of the fuel occurs. For this purpose the degasification chamber is cylinderical and is surrounded by a gasification compartment of annular construction separated from each other by a wall which is a good conductor of heat.

Title: Improvements in and relating to selective hydrogenation proceses
IPC: B01J37/20
Filed: 1948-06-30
Abstract: The selective hydrogenation of acetylene in the presence of a lower olefine is effected by passing the mixture with the addition of hydrogen in the proportion of at least 1 mol. hydrogen to 1 mol. acetylene over a reduced nickel oxide catalyst containing sulphur (see Group III) at 125-350 DEG  C.  The reaction may be effected under pressure and in the presence of inert gaseous diluents.  The Specification as open to inspection under Sect. 91 comprises also the selective hydrogenation of allylene or the butynes in presence of lower olefines, including propylene and the butylenes; or the hydrogenation of vinylacetylene in the presence of butadiene; or phenyl acetylene in the presence of styrene; or the hydrogenation of ethylenic linkages in the presence of aromatics; or the hydrogenation of a conjugate diolefine in the presence of the corresponding mono-olefine; employing the above catalyst. This subject-matter does not appear in the Specification as accepted.ALSO:A catalyst for selectively hydrogenating hydrocarbons (see Group IV (b)) is prepared by treating nickel oxide with a hydrogen-containing reducing gas at 200-600 DEG  C., and then with a sulphiding agent, e.g. hydrogen sulphide, carbon bisulphide, lower alkyl mer-captans, a solution of sulphur in benzene or toluene or a sodium polysulphide solution, until the sulphur content of the resulting catalyst is from 2 to 50 equivalents of sulphur per 100 equivalents of nickel.  In addition to nickel oxide the catalyst may also contain the following elements, either as such or in the form of compounds, e.g. oxides, A1, Cr, Mg, Mn, Si, Cu, Ag, Au, U, V, Ti, Th, Zr, Zn, Sn, Pb, Bi, Hg, Co, Fe, alkali; alkaline earth and rare earth metals, and platinum group metals.  The catalysts may be formed into pellets with the aid of lubricants, e.g. stearin or graphite, and sintered.  Alternatively they may be used in finely-divided form for the fluidized technique. They may also be supported on, e.g., carbon, clays and gels.  The nickel oxide may be prepared by precipitating the carbonate, igniting to oxide, pilling and sintering.  The Specification as open to inspection under Sect. 91 comprises also the incorporation of phosphorus, arsenic, antimony, selenium, tellurium and the halogens into the reduced nickel oxide instead of sulphur.  This subject-matter does not appear in the Specification as accepted.
