Abstract: 830,652. Moulding shoes. KELSALL, A. June 7, 1957 [June 14, 1956], No. 18341/56. Class 87(2). In a method of forming and securing a sole and/or heel unit to a shoe, the material for forming the unit is pre-heated, e.g. by high frequency electric heating, and then transferred to a mould containing the shoe, the mould having a movable member defining part of the wall of the mould cavity. A mould adapted to secure sole and heel units to a pair of shoes mounted on lasts 1 comprises side mould members 5, 8 between which the shoes are gripped by pressure applied to the movable members 5 by hydraulic pistons 20. The material, e.g. rubber or polyvinyl chloride compositions, for forming the sole and heel units is fed from a hopper (not shown) into a conduit 18 and is compressed by a ram 14 in a pre-heating chamber 15 when, parts 12 are closed by bottom mould members 11 during the moulding operation. The material in the chamber 15 is preferably subjected to high frequency electric heating. On completion of the moulding operation the members 11 are lowered by hydraulic pistons 22 to uncover the parts 12, the members 5, 8 separated, and the completed shoes replaced by others to be soled and heeled, which are clamped in position by the pistons 20. The ram 14 is then operated to force the material from the chamber 15 through the parts 12 into the mould cavities 16, and the members 11 again raised to apply the moulding pressure.

Filed: 1973-04-17
Abstract: 1412836 Anodes for electrowinning IMPERIAL METAL INDUSTRIES (KYNOCH) Ltd 22 April 1974 [17 April 1973] 18454/73 Heading C7B [Also in Division B3] A method of making a composite structure comprised of a precious metal bonded to a substrate of a film-forming metal includes assembling a sheet of precious metal foil 3 between a substrate 1 of a film-forming metal having a high electrical conductivity metal core 2 e.g. of copper or aluminium, and a protection and lubrication material 4, and rolling the assembly to elongate the components and metallurgically band them together. The precious metal is selected from the group platinum, iridium, rhodium, palladium, cerium, ruthenium, gold and alloys of two or more of these. The film-forming metal is selected from the group titanium, tantalum, niobrium, zirconium or an alloy of one or more of these metals having comparable anodic properties to the pure metal. The substrate comprises a titanium block drilled to receive cleaned copper cores 2, the block being pickled prior to receiving the cores. Platinum foil 3 is placed on the block and the block and foil are placed in a copper chest, which comprises the protection and lubrication material. A cleaned lid 5 is electron beam welded to the chest. The assembly is hot rolled to bond the foil, block and rods together and the copper chest is pickled off. Alternatively the composite structure is made by placing niobium sheets (8), (9), Fig. 2 (not shown), on either side of a copper core (7). Ruthenium foil, (10), (11) is placed on the sheets (8), (9) and a pair of dished copper plates (12), (13) are placed on the ruthenium layer and crimped together at their edges (14). The surfaces of the components are cleaned before assembly. The assembly is hot rolled to produce a copper core niobium block faced with platinum after the plates (12), (13) have been pickled off. The protective material prevents the precious metal being picked-up during rolling and is readily lubricated. The composite structure may be used as an anode in the electrowinning of copper in which case the outer copper sheets can be left in position as they will be removed electrolytically during initial operation of the electrowinning cell.

Abstract: 632,339. Steering means for mechanical toys. HARDY, N. S. July 16, 1947, Nos. 18932 and 23383. [Class 132(iii)] A toy vehicle containing a propelling motor comprises steering means, a cam on the side face of a gear or other rotary member driven by the motor, a cam follower displaceable by the cam, connections between the cam follower and the steering means to operate the latter while the vehicle is moving, and adjustment means for shifting the rotary member axially to vary the displacement of the follower by the cam. As shown, the chassis 1 of a toy car is provided with steerable wheels 2b (only one is shown) and the driving motor 3 operates a gear 18 carrying a cam 4 which displaces a cam follower 5. The wheels may be mounted on stub axles 6a, 6b, each capable of movement about a substantially vertical axis and connected together by a track rod 7. Spring means 8 bias the wheels into the " straight ahead " position and similar spring means may be used to bias the cam follower toward the cam. The track rod 7 is connected to the cam follower by a crankshaft 9, one end 11 of which engages in a fork 10 on the track rod such that displacement of the follower rocks the crankshaft 9 shifting the track rod 7. To ensure contact of the wheels with the supporting surface despite irregularities thereof the stub axles 6a, 6b are pivotally mounted on an axle carrier 15 extending transversely across the vehicle and centrally pivoted at 16. The stub axles are conveniently mounted directly on trailing levers 13a, 13b pivoted to the carriers 15, to which levers 13a, 13b, the ends of the track rod are pivoted. The motor may be driven by clockwork, electricity, elastic, internal combustion, hot air or steam means. The cam 4 may consist of a stud or other protrusion on the gear 18. The extent of rocking of the cam follower and the angle through which the steering wheels are temporarily displaced are adjusted by axial displacement of the cam gear 18. This may be done by endwise shifting the spindle 22 carrying the gear by forming on one of its ends 22c a screw thread to enable it to carry a nut 23. A spring 24 may be mounted on the spindle 22 to thrust against the gear and the chassis. Preferably one flank of the cam is inclined so that axial displacement of the gear alters the duration of displacement of the cam follower.
