Title: Auxiliary brake applying mechanisms for a combined disk and shoe-drum brake
IPC: F16D55/14
Filed: 1955-10-18
Abstract: 783,035. Combined disc and shoe-drum brakes. BENDIX AVIATION CORPORATION. Oct. 18, 1955 [Nov. 4, 1954], No. 29724/55. Class 103 (1). In a combined disc-and shoe-drum brake in which two friction units 10, 12, pivotally supported on anchors 14 fastened to torque-plate 16 are provided with friction elements 20 spread apart by fluid pressure actuator units 18 to engage surfaces 22 and 24 of rotor 26 and each friction unit is provided with a shoe element 28, engageable with surface 30 of the rotor, and supplied by the torque developed from engagement of the friction elements 20 with the surfaces 22 and 24 of the rotor, an auxiliary brake is supplied comprising two mechanically applied oppositely acting friction members. The auxiliary brake applying mechanism comprises a pair of oppositely-applied friction members 32 and 34 actuated by articulated levers 37 and 39 which are joined by pin 38. Lever 37 is fulcrummed at point 40 on torque plate 16 through ball-joint connection 42 and a flexible cable 44 passes through ball-joint and its end is fastened to lever 39. Between friction members 32 and 34 is provided spring means for disengagement and a camming device (not shown) is provided for spreading the friction members and imparting pivotal movement to the unit 10 when friction members shift with the rotor. Ball- and-socket joints 56 are provided to permit swivelling movement between the applying ends of the levers 39 and 37 and friction members 32 and 34. In operation, assuming clockwise rotation of rotor, when auxiliary brake is applied by pulling on cable 44 to operate levers 37 and 39, the retarding force of friction members 32 and 34 on rotor will cause shifting of the friction members 32 and 34 therewith on camming device relative to unit 10. Clockwise turning of unit 10 about its anchor 14 communicates effort to unit 12 through force transmitting member 58 to induce clockwise movement of unit 12 about its anchor 14, thereby engaging shoe portion of unit 12 with surface 30 of rotor 26. Specifications 767,706, 767,914 and 775,237 are referred to.

Title: Improvements in or relating to draw benches
Inventor: ROBERTS HENRY WALFORD
IPC: B21C19/00
Filed: 1965-07-14
Abstract: 1,108,381. Draw benches. PATENTS & INVESTMENTS Ltd. 26 Aug., 1966 [14 July, 1965], No. 29770/65. Heading B3P. A chain driven draw bench has means for disengaging the hook from the chain at the end of the drawing operation and time delay means associated with the disengaging means to cause operation of the latter after a predetermined time interval has elapsed after the workpiece, or all of the workpieces, has, or have, left the die-plate. In the machine shown in Fig. 2 the die plate is mounted on the bracket 17 and the carriage 28 is moved away from the die-plate by a chain 13. At the end of the draw the carriage is returned by a cable 52 driven by a motor 50. During the draw, the part of the workpiece between the die-plate and the carriage is supported by horizontal arms 39 which swing from the solid line position to the dotted line position as the carriage passes. The arms are mounted on vertical spindles and actuated by reciprocating cylinders 46. Each cylinder is controlled by a valve which is tripped as the carriage passes. Grippers mounted on the carriage are controlled by an aircylinder 37 and the hook is actuated by an aircylinder 30. The bracket 17 which supports the die plate is strengthened by two buttresses 20 which extend away from the bracket in the direction of drawing. At the end of the draw the workpieces are removed laterally from the bench by the return of the arms 39 to the solid line position. In order to prevent the lateral movement occurring until the trailing ends of the workpieces are clear of the buttresses 20 the hook remains in engagement with the chain for a predetermined interval of time after the last of the workpieces has left the die-plate. This is achieved by mounting a micro-switch on the bracket 17 and operating it by an arm 25, the micro-switch being connected to a time-delay relay which controls the hook cylinder. The dieplate 18, Fig. 3, is movable about a pivot 19 which is positioned in relation to the dies 21 so that when the workpieces are being drawn the plate 18 pivots clockwise and operates the arm 25. The plate is spring-biased to rotate anticlockwise. The workpieces are lubricated by oil-bath apparatus connected to sleeves 23.

Title: Process and plant for the production of sponge iron
IPC: C21B13/00
Filed: 1962-08-03
Abstract: Sponge iron is produced in a shaft furnace by the reduction of lump or sintered iron ore with a reducing gas obtained by cracking hydrocarbons with steam or oxygen in cracking furnaces, the cracking being carried out in the presence of waste gas from the reducing furnace.  When oxygen (which may be in the form of pure oxygen, oxygen-enriched air or air) is used in the cracking furnace 60-75% of the waste gases may be recirculated thereto, and when steam is used, 20-40% of waste gases may be recirculated ; in either case the molecular ratio oxygen:methane in the mixture is maintained at 1:1. Up to 30% of the recirculated gases may be withdrawn before the cracking plant and fed to the bottom of the shaft for cooling the product.  The waste gases not recirculated are used to heat the cracking furnaces.  In the embodiment shown in Fig. 1, shaft furnace 1 is associated with two cracking furnaces 3 and 4, one of which is in use while the other is heating-up.  Waste gas leaving through conduit 5 is divided, one part passing through pipe 7 and being burnt with hot blast from recuperator 8 to heat furnace 4.  The other portion passes through pipe 6, and may be further divided, one part passing to the base of the furnace for cooling while the other passes to furnace 3 where it is mixed with steam or oxygen and hydrocarbon in chamber 13, Fig. 2, before reacting in chamber 14 at about 1000 DEG C. <PICT:1004006/C6-C7/1> <PICT:1004006/C6-C7/2>

Title: Connector for cables of optical fibres
IPC: G02B6/40
Filed: 1975-07-17
Abstract: 1508455 Optical fibre connectors G LE NOANE 17 July 1975 [26 July 1974] 30134/75 Heading G2J A connector for connecting in end to end relation the individual fibres of two optical fibre cables comprises a male half 100 and a female half 200. In both halves a cable sheath gripping sleeve S1(S2) is engaged by a retaining nut 117(217) and in turn engages a metal piston 115(215) axially slidable in a central bore of the connector half. An elastomeric plug 113(213) is compressed in the bore by the piston 115(215). A further similar elastomeric plug 127 is urgable to the left by a larger piston 121 under action of nut 129. An interconnecting nut 230 on the female half secures the halves together. In their initial states the interconnecting nut 230 and nut 129 are screwed back, and each connector half bears a moulded-on plastics washer (135), (235), Fig. 2A (not shown), whose end-face is generally coplanar with the joining end surface of the respective connector half. Each washer bears a central short axial extension (137) (237). Aligned bores (some three times the diameter of the individual optical fibres for which the connector is intended) extend throughout the components parts of both connector halves, keys (243), Fig. 2E (not shown), in keyways ensuring correct angular alignment of the two halves about the axis of the connector. Operation The ends of the cables to be joined are stripped to expose the individual fibres, which latter are inserted in their respective bores until they emerge from the other ends of the connector halves 100, 200. Tightening of nuts 117, 217 cause both the cable armouring to be anchored by sleeves S1, S2 and the individual fibres to be anchored by compressing plugs 113, 213. The axial extensions (137), (237) Fig. 2A (not shown), of the washers  are ground off to leave the end-faces of the washers (135) (235) flat and coplanar with the connector ends, thereby giving the individual fibre ends the correct length and orientation. The washers (135), (235) are ejected by movements of nuts 129, 230 and the connector halves secured together by nut 129 whereby the individual fibre ends are brought into loose contact. Movement of nut 129 to the left pushes elastomeric plug 127 to cover the joins of the fibre ends, and compression of the plug anchors the joined ends in correct alignment. Two embodiments are envisaged (1) each of plugs 113, 213, 127 and associated pistons 115, 215, 121 have a plurality of bores, one bore for each individual fibre. In this case the plugs and pistons are keyed so as not to rotate within the connector bodies. (2) each fibre has a respective plug and piston at each end and at the join. A matching fluid may be incorporated between the fibre ends.
