Inventor: CLOW COLIN GEORGE
IPC: B22F3/04
Filed: 1959-11-02
Abstract: 895,492. Moulding powdered materials. GENERAL ELECTRIC CO. Ltd. Nov. 1, 1960 [Nov. 2, 1959], No. 37176/59. Class 87(2). An elongated article such as a tube is produced by forming a compact by applying hydrostatic pressure to an elongated mass of powdered material such as a nickel-based alloy or a metal oxide located in a rubber mould 8 which is clamped between end members 11, 11<SP>1</SP> and a perforated tube 9 and immersed in pressurized glycerine, the pressure through the perforations being substantially radial and the longitudinal pressure on the powder being considerably less than the hydrostatic pressure. The mandrel 10 is withdrawn from the pressing which is then sintered. A preliminary pressing may be produced using the apparatus shown and the pressing may then be subjected to full hydrostatic pressure in all directions. A plurality of mandrels 10 may be used and the pressure may be applied at up to 40 degrees from the transverse or radial direction. Cylindrical rods are produced in the apparatus of Fig. 1 (not shown).

Abstract: 970,568. Gearing for converting rotary into reciprocating motion. FMC CORPORATION. Oct. 2, 1962, No. 37400/62. Heading F2Q. [Also in Division B1] A carriage 109, Figs. 9 and 10, is slidable on fixed guide rods 107, 108, and includes two lower parallel bars 123, 124 (Fig. 9 being an underneath view), between which a roller 122 is accommodated, and two upper parallel bars 127, 128, between which three rollers 121, 131, 132 are accommodated. The roller structure is secured to a chain 114, Fig. 9, driven by a sprocket 115, Figs. 9 and 11, and engaging a further sprocket 116, Fig. 9. Movement of the chain effects reciprocation of the carriage and hence of rods 54 which are secured to the carriage. To enable the carriage to pass the downwardly-directed shaft 117 of sprocket 115 (see Fig. 11), slots 129, 130, Figs. 9 and 11, are cut in bars 127, 128. It is these slots which necessitate the provision of the three rollers mentioned above; when one roller of the three (121, 131, 132) is aligned with slots 129, 130, the other two will be supported between the bars and provide the necessary balance for roller 122.

Abstract: 500,279. Continuous metal - heating furnaces. LUCAS, E. E., and PLATT, G. W. Jan. 6, 1938, No. 374/37. [Class 51 (ii)] In a continuously-operated furnace for the heat treatment of metal articles having a feed opening 5 at one end, and at the other a door opening 18 as well as a passage 15 leading to a quenching-tank, arrangements are provided by which air entering or tending to enter the heating- chamber when the ends are open will be diverted to the stack. The closure 9 for the opening 5 is in the form of a feed ram for trays 3 containing the work to be treated, and is so dimensioned-that, in its closed position it will cover the inlet to a flue 6 leading to the stack 8. At the opposite end the space between the end of the heating-muffle 1 and the door 18 is in communication with the stack through ports 24 and recuperator flues 23. Heating of the muffle is effected by burners delivering alternately from opposite sides of the furnace into transverse flues 20, and the products of combustion flow along the top of the muffie to the discharge end where they pass down side flues to the space beneath the inclined plate 14, and thence through the flues 23 to the stack. The trays 3 are of the three-sided form shown in Fig. 4, and their movement down the slope 14 is arrested by stops 16, so that the articles will be shot down the passage 15 to the quenching-tank. The empty trays are removed through the doorway 18. The muffle has a pivoted flap 12 at its discharge end, and connections 1a for the supply of protective gas.

Abstract: 1,162,551. Electrode construction for electrolysis of a fused electrolyte. NORSK HYDRO - ELEKTRISK KVAELSTOFAKTIESELSKAB. Aug. 22, 1966 [Sept. 1, 1965], No.37613/66. Heading C7B. An electrode construction for the electrolysis of a fused electrolyte (e. g. for producing Mg and Cl 2  from Mg Cl 2 ) comprises an anode and a cathode each having opposed vertical working surfaces with cathodic members extending away from the vertical cathode working surface and (1) underneath the anode or (2) into a recess or recesses in the vertical anode working surface, each cathodic member being spaced from other cathodic members over at least part of its working surface. Fig. 3 shows cathode shafts 1 leading to cathode parts having transverse cathode members 3 between their lower ends. The transverse cathode members pass through recesses in a central anode 4, 5 built up from alternate long and short rods Fig. 2 (not shown). The recesses are so shaped at 6 as to guide the flow of electrolyte during electrolysis. Auxiliary cathodes 2 are provided. Partitions 7 form part of a hood, e. g. of ceramic, for collecting anode gas. Alternative constructions comprise cylindrical anodes and concentrically arranged cathodes with cathodic members either in the form of parallel plates or star-shaped, the centre of the star being on the axis of the anode so as to divide the lower part of the anode into segments. Electrical connection may be to the top of a cathode or to the transverse members. The cell walls can be made of steel in which case thetransverse cathode members can extend between opposite cell walls. The examples are of electrolysis using an electrolyte consisting of 15% by weight of MgCl 2 , 35% CaCl 2 , 30% NaCl and 20% KCl.

Title: Production of furfuryl alcohol resins
IPC: C08G65/36
Filed: 1966-08-25
Abstract: Furfuryl alcohol resins are obtained by heating furfuryl alcohol in the presence, as catalyst, of antimony oxide and separating the catalyst after the formation of the resin.  The heating is carried out at a temperature of 120 DEG  to 180 DEG  C. and the reaction may be discontinued by cooling.  The catalyst is removed by decantation and/or filtration and/or centrifugation, and the unreacted furfuryl alcohol may be removed by distillation.  The furfuryl alcohol resin may be cross-linked by the action of a catalyst alone or by the action of a catalyst and heating. The reaction may be carried out in the presence of a water entrainer, e.g. benzene, cyclohexane or ethyl acetate, which azeotropically entrains the reaction water as it is formed.

Abstract: 967,278. Lifting weight off springs. THEW SHOVEL CO. June 7, 1961, No. 38812/63. Divided out of 967,277. Heading B7D. [Also in Divisions B8 and E1] An outrigger arm for extension from a vehicle such as a mobile crane or excavator into a ground-engaging position in which the vehicle is stabilized against tilt in use, consists of a linearly extensible beam, power means for extending it and friction means for preventing its retraction once it has engaged the ground. The outrigger beam comprises two telescopically retractable tubes 38 and 39, tube 39 being attached by a cross-pin 44 to the piston 43 of an hydraulic actuator 40. The latter when energized pushes tube 39 until its flanged inner end strikes an internal stop (not shown) approximately halfway down the surrounding tube 38 which then moves with the tube 39 until a ground-engaging float 51 at the outer end of tube 39 meets the ground. The float 51, which falls under gravity about perpendicular pivots 49 and 52 to lie parallel with the ground when the outrigger is extended, is guided into the position shown when it is retracted. The radially outer surface of the flanged inner end of tube 39 provides an area of friction contact with tube 38; this, together with a further friction area between the two tubes and between tube 38 and the surrounding fixed mounting 30 (these latter friction areas being provided by flanges at both ends of tube 38), causes the arm as a whole to be self-stable against accidental retraction once the ground has been engaged by float 51. Specification 875,857 also is referred to.
