Abstract: 1,233,039. Grinding. K. HACK. 13 Dec., 1968 [15 Dec., 1967], No. 59402/68. Heading B3D. A machine for grinding the ends of springs 23, Fig. 2, comprises a pair of coaxially arranged grinding wheels 6, 7 one at least of which is adjustable in its axial direction, and a pair of transporting plate assemblies 16, 17, Fig. 3, each of which is rotatably mounted on a pivot arm 11, 12 on which it is pivotable about an axis 13, 14 parallel to the axis of the grinding wheels between a working position in which it is partially disposed between the grinding wheels and a charge and discharge position, each of the assemblies 16, 17 being supported from an overlying bearing and drive means 25. In the machine described the springs 23 are carried in apertures 22 in pairs of discs 20, 21, Fig. 1, forming the assemblies 16, 17, and are supported therein by a table 9. The table has closable openings 27, 28 which when open allow discharge of the springs from the plates when the latter are in the charge and discharge position. Each pivot arm 11, 12 is moved manually, mechanically or, as shown, by a pneumatic piston and cylinder 33, and is cranked so that when both plates 16, 17 are in their charge and discharge positions the distance between the plates is greater than the diameter of the grinding wheels. In another embodiment the arms 11, 12 have a common pivot axis in front of the grinding wheels. The assemblies 16, 17 may be rotated at different speeds depending on their positions.

Abstract: 1,238,253. Continuous casting. TSENTKALNY NAUCHNO - ISSLEDOVATELSKY INSTITUT CHERNOI METALLURGII IMENI I.P. BARDINA. 7 Feb., 1969 [9 Feb., 1968], No. 6819/69. Heading B3F. A rectangular continuous casting mould has four walls 1 of copper, the lower corners of which are cut away at 2. Ceramic or metal members 3 (Fig. 3) are placed in the corners leaving a gap 4 in the mould cavity. The lower portions of the walls are provided with longitudinally slotted surfaces 7 having plane boundaries 10. Superheated steam is fed as a coolant to the slots by bores 9 whilst heaters 6 are placed in the corners of the moulds. Consequently, a billet cast in the mould is cooled more quickly at its faces than at its corners. The rate of heating and supply of coolant can be controlled to ensure uniform thickness of the solid metal skin as the cast billet leaves the mould.

Abstract: 1,259,381. Iron oxide catalysts. H. F. A. TOPSOE. 28 Jan., 1970 [6 March, 1969], No. 11930/69. Heading B1E. [Also in Division C1] A high temperature shift catalyst comprising iron oxide characterised by the presence of less than 50 ppm sulphur (claimed per se) is prepared by precipitating iron as a salt of an organic acid from solutions of iron salts in the form of coarse crystals, washing the precipitate to remove soluble impurities, then treating the precipitate with an alkali solution to obtain a flocculent iron oxide of high specific surface area and regenerate the organic acid reagent. The alkali solution may be NH 4 OH, NaOH, KOH. The organic acid may be oxalic acid and is preferably added in the form of its ammonium or alkali metal salt. The catalyst may contain Cr 2 O 3  and/or PbO as promotors. The precipitation of ferrous oxalate may be carried out at room temperature and the hydrolysis by means of the alkali solution at a temperature between 50‹C and 100‹C. The promotors, e.g. Cr 2 O 3 , PbO, may be added by treating the resulting Fe(OH) 2  suspension, after washing, with their soluble nitrates. Mixed oxide catalysts may also be prepared by the process of the invention by treating solutions containing soluble salts in addtion to the iron with the ammonium or alkali metal salt of an organic acid, e.g. oxalic acid.

A closed fluid circulating system for cooling apparatus 8, e.g. a cryo-surgical instrument or vacuum plant, comprises a pump 6 for circulating helium or hydrogen through a heat exchanger 2 associated with a cold source 7, e.g. a refrigerator, a duct 3, a heat exchanger 4 associated with the apparatus 8 and a duct 5. The system also includes a cold store 9 in the form of a regenerator having a by-pass 10, the flow of cooled fluid to the store and by-pass being controlled by a slide valve 12. Further bypass ducts 13, 16 connecting the ducts 3, 5 are controlled by slide-valves 14, 18 to control fluid flow to the heat exchangers 4, 2 respectively. A heating device 19 is mounted in the duct 16 to supply heated fluid to the apparatus 8 when required. In operation, cold is stored in the regenerator 9, the fluid passing through the circuit but by-passing the heat exchanger 4 through the duct 13 until required when valve 14 is opened and the fluid passes through the regenerator to supply cold to the exchanger 4 for a given period at a constant low temperature and at a rate greater than that possible by the refrigerator alone. In various modifications, the relative positions within the system of the cold store and valves are altered.

Abstract: 1290119 Making spectacle frames ROBERT HELLERICH KG 23 April 1971 [12 Sept 1970] 10930/71 Heading B3A A process of making polygonal spectacle glass rims comprises cutting a profiled wire 1 into pieces of the desired length feeding each piece through a curved passage to prebend said piece and then subjecting each piece to an automatically controlled, intermittent hammering operation to form predetermined bends in said piece after it has been prebent. The wire is fed through a guide 2 by gripping jaws 3 to cutter blades 4 which cut the wire into pieces 5. Each piece is then pushed through a guide 6 which merges into curved passages 7a and 7b formed in bending dies 8a and 8b (Figs. 2 and 3, not shown). A stationary guide roller 9 positioned at the outlet of the passage is succeeded by a roller 11 mounted on a carriage 10. A hammering movement is imparted to the roller 11, by pneumatic or hydraulic power and is controlled by a pivoted rod 13 provided with recesses a to d which engage a roller 10a carried by the carriage 10. A second hammering movement at an angle to the first is electrically controlled by cams e to h on the rod 13 which control a pneumatically or hydraulically driven hammer lever 14. Whereas the lens rim has been slightly bent forwardly by the first meniscus bending the rim it is bent back into its plane by the second hammering movement. A blade 20 for marking the bridge bow position precedes the bending dies and is controlled by the rod 13.

As shown, the module comprises four piston type control valves 15 having inlet and outlet connections 13, 14, and operated by a tiltable cylinder 12 with a bottom plate mounted on a ball-and-socket joint 19 and engaging the control valve stems 16. The cylinder carriers an additional piston control valve 21 which is biased to a neutral position and has inlets and outlets 13a, 14a at opposite ends. The pistons control multiple ports 13b which are plugged at their exterior ends and connected to the inlets and outlets. The additional piston valve 21 is operated manually by a rod having a hand knob 23. This handle also controls tilting of the cylinder to operate the valves 15. The module is incorporated in a system, Figs. 2 and 3 (not shown), for controlling a universally pivoted jib, e.g. of a rock breaking tool, in bearing and elevation and for extension and retraction of the jib. Preferably the latter movements are controlled by the push-pull motion of the handle 2.
