Filed: 1954-09-20
Abstract: 751,582. Turbine and compressor rotors. SULZER FRERES SOC. ANON. Sept. 20, 1954 [Sept. 30, 1953], No. 27219/54. Class 110(3) [Also in Group XXIV] A turbine or compressor rotor comprises a number of discs 3, 4, 5 connected together by welding 7, overlapping annular flanges 9, 10 being provided on adjacent discs, which flanges have at least two pairs of engaging surfaces 11, 12. At least one pair of surfaces 11 serves to transmit outwardly directed radial force from one disc to an adjacent disc, while at least one other pair of surfaces 12 serves to transmit inwardly directed radial forces from the former disc to the latter disc. In Fig. 1, the rotor comprises end discs 1, 2 which are bored to receive supporting shafts, and discs 3, 4, 5 which carry rotor blades 6. and the surfaces 11, 12 are cylindrical. In a second embodiment four pairs of engaging surfaces are provided and they are of frusto-conical form. In operation, the disc 5, for example, expands to a greater extent than the adjacent disc 4 and so outward force is transmitted from the disc 5 to the disc 4 through the surfaces 11. Due to the effect of creep, permanent deformation of the material may occur so that the radial forces will disappear. When the rotor is allowed to cool, the disc 5 will contract more than the disc 4 so that inward radial force is transmitted from the disc 5 to disc 4 through the surfaces 12.

Patent GB-915032-A (GB)
Title: Alloy resistance elements and methods of making them
IPC: H01C7/00
Filed: 1959-08-11
Abstract: A nickel-chromium coating is formed on a glass or glazed ceramic base by heating the base above 350 DEG  C. but below the melting temperature of the glass and subliming at a low pressure and in a controlled supply of oxygen a nickel chromium alloy.  The oxygen enables a bonding layer of chromium oxide or oxysilicate to be formed which bonds the nickel chromium to the base.  The oxygen required may be supplied separately to the vapour deposition apparatus or the glass base may be preheated in an oxygen-containing atmosphere at a temperature below the glass fusion point, or oxygen may be supplied by a combination of both methods.  The oxygen containing glass which may also contain oxygen liberating substances is heated to at least 350 DEG  C. in a vacuum of 10-5 mm. Hg and a nickel chromium filament heated to at least 100 DEG  C. below its melting-point is sublimed on to the heated base.  The oxygen diffuses to the surface of the heated base and reacts to form the chromic oxide bonding layer.  The coated base is then stabilized by heating in oxygen at 140 DEG  to 180 DEG C.

Abstract: 1392073 Injection mould; blow moulding K HEHL 13 June 1972 [16 June 1971 28 June 1971] 27526/72 Heading B5A A component, 9 or 100, of an injection mould is mounted on one end of a drive shaft 15, the axis of which is coincedent with the axis of symmetry of the mould lying in the mould closing direction, the shaft having two opposed helical grooves 17, 18 engaged by control pins 24, 25 to cause rotation of the shaft 15 and thus of the component 9, 100 on opening or closing of the mould. A plate 9 is mounted on the shaft 15 between a stationary mould half 1 having cavity inserts 8, 40, and a movable mould half 19 carrying cones 20, 21. In use the mould assembly is closed, a first material injected through a sprue 5 into cavities 40 and a second material injected through a sprue 6 on to already formed first parts in cavities 8. As the mould is opened the plate 9 travels with the mould half 19 until shaft 15 is arrested by abutment 39, whereupon it is separated and rotated through 180 degrees by the pins 24, 25 engaging the helical grooves and rotating the shaft 15 as it passes through the mould half 19. The completed articles fall from the mould as cores 21 are withdrawn, but the part articles are held by recesses 10<SP>1</SP> in the plate 9 and are thereby moved into position for entering the cavities 8 for the second injection. The sprue 5 is retained by a portion which enters a recess 14 until an ejector 13 in shaft 15 is operated by striking abutment 39. Sprue 6 is retained against plate 9 by pins 12 which enter the sprue, but falls away when the pins are withdrawn through the plate 9. When the mould is closed again the pins 24, 25 slide down straight grooves 44 joining the straight positions 17<SP>1</SP>, 18<SP>1</SP> at the opposite ends of the two helical grooves, thus the plate 9 does not rotate. The plate 9<SP>1</SP> may be replaced by a core support 100, Fig. 7, having two rows of opposed cores for blow moulding bottles 14 from injection moulded parisons 113.

Title: Improvements in the production of ruthenium compounds
Inventor: KEATTCH CYRIL JACK
IPC: C01G55/00
Filed: 1960-08-09
Abstract: Ruthenium dioxide monohydrate is obtained by reducing ruthenium tetroxide with hydrogen gas at a pressure not exceeding 100 p.s.i.g. and at a temperature below 50 DEG C. and preferably greater than 30 DEG C.  If hydrogen pressure below 15 p.s.i.g. is used it is preferred to carry out the reaction in the presence of an additional inert gas, e.g. nitrogen or argon, to make the total pressure in the reaction vessel at least 15 p.s.i.g.  The reduction of the tetroxide is carried out in a pressure vessel, e.g. a heavy-walled spherical glass reaction vessel.  Preferably the process is carried out in the presence of water.  After the hydrogen to reduce the tetroxide has been admitted under pressure the reactants are shaken and when no more hydrogen is taken up, the reaction product is separated from the water, washed and dried at 110 DEG  to 130 DEG C.  A catalytic oxidic ruthenium compound is obtained by heating ruthenium dioxide monohydrate at temperatures up to 900 DEG C.  Supported catalysts may be prepared by reducing ruthenium tetroxide to ruthenium dioxide monohydrate by means of hydrogen in the presence of a suitable support on which the product forms a coating.  Supports mentioned are inert particulate materials, e.g. alumina, and metallic supports, advantageously a metal gauze or an expanded metal, the metals mentioned being titanium, nickel, silver, tungsten and molybdenum. To ensure that the catalyst adheres, the surface of the metal should first be roughened, e.g. by etching or sand blasting.
