Title: Method and apparatus for molding thermoplastic material
IPC: B29C33/72
Filed: 1968-02-07
Abstract: 1,208,348. Slush moulding apparatus. GOODYEAR TIRE & RUBBER CO. 7 Feb., 1968 [27 Feb., 1967], No. 6178/68. Heading B5A. Thermoplastic articles are slush moulded in a process comprising (a) heating a mould to a temperature above the fusion temperature of the thermoplastic material by passing a heating medium through the mould walls, (b) rotating or oscillating the mould while in contact with a supply of thermoplastic material, (c) removing excess unfused thermoplastic material from the mould, (d) cooling the mould by feeding a cooling medium to displace the heating medium and (e) stripping the moulded article from the cooled mould. As shown, the moulds 12 are mounted on a framework 7 rotatable in bearings 8. Heating and cooling fluids are supplied through valves 1 and 2, pass through pipes 3 and 5, bearings 9 and flexible pipes 4 to the mould jackets and return to valves 29 and 34. The lower side 13 of the mould is open, and engages with the polymer supply vessels 18 which are raised on platform 20 by ram 19. The vessels 18 are held against the mould 12 by a pneumatically operated bolt 21 (not shown) and remain in contact during the moulding cycle. The platform 20 also carries a compressed air line which engages with an outlet in the mould and permits excess material to be blown from the moulded surface. The operating cycle may be controlled automatically and is as follows. Valves 1 and 29 are opened to allow heating fluid to raise the mould temperature. Ram 19 is extended bringing vessels 18 into contact with the mould 12 and these vessels are fixed together by bolt 21. The ram 19 is then retracted and the mould is rotated or oscillated by motor 14 driving sprocket 16. After a suitable period, oscillation is stopped with the vessels 18 at their lowest point and the ram 19 is raised. Loose powder (when used) on ledges in the mould is removed by a jet of air, the bolt 21 is retracted and the vessels 18 are lowered on to table 20. The heat is maintained for a short time to completely fuse the powder then valves 1 and 29 are closed and valves 2 and 34 are opened, forcing cooling fluid round the mould and expelling hot fluid already present in the mould channels. When the mould has cooled sufficiently, the article can be removed, the mould cleansed and the cycle restarted.

Title: Improvement in power actuator for the brake mechanism of automotive vehicles
IPC: B60T13/24
Filed: 1926-03-05
Abstract: 250,195. Bragg, C. S., and Kliesrath, V. W. April 3, 1925, [Convention date]. Fluid-pressure; hand, foot, and personal actuation. - A fluidpressure brake for motor vehicles comprises a single-acting piston and controlling valves within the piston and operated by the foot-lever which is connected to the mechanism by means providing lost motion sufficient to operate the controlling valves and allowing physical force to be exerted on the brake mechanism when desired. The piston 5, Fig. 2, operates in an open ended cylinder 1 and contains in its hub 7 the controlling valves 40, 41. The valve-actuating sleeve 20 passes through the hollow piston-rod 11 and is connected to the footlever by a lug 28. Stop collars 23 44 arrest the sleeve 20 and piston-rod 11 respectively in such a position that the valves 40, 41 through which the sleeve 20 is movable, are normally held seated by a soft rubber annular member 50. On applying the brakes, the valve 41 is unseated by a collar 26 on the sleeve 20 and connects the interior of the cylinder 1 to the induction pipe of the vehicle engine through the sleeve 20 and a pipe 30. The consequent movement of the piston applies the valves through a lug 36 screwed in a part 7a of the piston hub and also recloses the valve 41 if the foot lever is held stationary thus maintaining the brakes in operation. If the footlever is released, the valve 40 is opened by a collar 25 on the sleeve 20 and the cylinder 1 is connected to atmosphere through the hollow piston-rod 11 and openings 16, thus releasing the brakes. A plug 31 is screwed in the end of the sleeve 20, and is provided with a head 32 which abuts against a shoulder 34 in the part 7a of the piston hub when it is necessary to apply physical force to the brakes. The return spring 37 for the mechanism is contained in the part 7a and abuts against the head of the plug 31. A packing for the piston-rod 11 comprises a rubber sleeve 13 secured in position by a flange 15. In a modification in which the mechanism is arranged forward of the foot-lever, the valve-actuating sleeves projects rearwardly of the piston hub instead of through the piston-rod and is connected by a link 193, Fig. 3, to the foot-lever 188 which is pivoted on a lever 174 pivoted to the chassis. Power is transmitted to the brakes through the lever 174, which is connected at 174a to the brake rod 173 and at 179 to the piston-rod by a connection 185. The brakes are applied by physical force when a set-screw 194, passing through the foot-lever, engages the lever 174. An adjustable stop 143 limits the return movement of the foot-lever so that the valveactuating sleeve is normally maintained in such a position that both valves are seated. The connections to the levers 188 and 174 are adjustable by means of a plurality of apertures in these levers

Title: Improvements relating to the production of pig iron
IPC: C21B13/10
Filed: 1965-02-12
Abstract: Pig-iron is produced in a stationary hearth, particularly a Siemens-Martin furnace 1 charged with iron ore, solid carbonaceous material such as coal or coke breeze, and limestone, with or <PICT:1097135/C6-C7/1> without scrap containing Fe2O3, by introducing e.g. from one or more lances or burners 3 an oxygen-containing gas stream 12 directly into the furnace chamber to impinge on to part of the charge (Zone I) and react with the carbonaceous material to produce a reducing gas such as CO and H2 (Zone II) which passes through the advancing part of the charge to heat and reduce it (Zone III), and to produce heat to melt the pig-iron formed. The gas stream may be oxygen of at least 95% purity or formed by combustion products of oxygen and heating oil burnt on introduction into the furnace chamber.  20 to 80% by weight of the total carbon required may be contained in either the burner fuel or solid carbonaceous material. The oxygen to fuel ratio of the gas stream is preferably at least 0.7.  10 to 50% by volume of the gas stream may be directed on to the molten pig-iron.  Before passing into the hearth furnace, the charge may pass through a rotary tube furnace 8 where 40 to 70% by weight of the ore is pre-reduced (Zone IV) by waste gases from the hearth furnace, any remaining burnt by additional air.  To reduce the amount of solid carbonaceous material in the charge, gaseous or liquid carbonaceous material may be introduced into the solid charge near its junction with the molten pig-iron; high carbon pig-iron may thus be produced.
