Title: Clasp Engageable with Enlargements on Cables and the like
Inventor: METZ JOSEPH R
IPC: F16G11/00
Filed: 1967-09-21
Abstract: 1,180,997. Clamps; releasable fastenings. NORCO Inc. 21 Sept., 1967, No. 43100/67. Heading E2B. A clamp for gripping an enlargement on an elongated member, e.g. ball 20 on cable 18, comprises a tubular body 10, a pair of semi-cylindrical wedging shells 22, 24 which together define a seating 26, 28. for the enlargement, a spring 34 urging the shells towards end 14 of the body, co-operating wedging surfaces on the body and shells causing the latter to grip the enlargement upon such movement, and means, slidable longitudinally on the exterior of the body member for moving the shells to the right, as shown in Fig. 1, to permit the release of the enlargement. The means may comprise a sleeve 36, provided with two radial pins 38, which extend through slots 40 in the body and engage in slots 42, 44 of the shells. These latter slots are axially elongated to permit movement of the shells to the right without moving sleeve 36. The shells are pivotally connected by two balls 50, located in diametrically opposed recesses, each recess being formed by a depression of one shell facing a depression in the other. A fitting 12 facilitates attachment of the clamp to a support. Alternatively, the fitting may be formed with a through bore allowing passage of the cable 18 and ball 20, Fig. 4 (not shown). The clamp may comprise two pairs of wedging shells, one at each end of the body 10, Fig. 5 (not shown). In a modification, Fig. 6 (not shown), the wedging shells are formed with peripheral ridges at what would be their left-hand ends as shown in Fig. 1. When the ball 20 is engaged in its seating, these ridges engage in corresponding recesses formed in the body 10 so that movement of the shells to the release position is prevented until the ball has been moved from its seating.

Title: A conveying installation for carcases of slaughtered animals
IPC: A22B7/00
Filed: 1965-10-13
Abstract: 1,121,754. Conveyor systems. N.A.O. MEIER [trading as W. MEIERS EFTF. V/AXEL MEIER and MASHINFABRIKEN W. MEIERS EFTF]. 13 Oct., 1965 [14 Oct., 1964], No. 43483/65. Heading B7L. Animal carcases carried by hooks are movable along a round bar 1 Fig. 2, suspended by brackets 2 from U-sectioned members 3, 4, by a driven endless chain 7 guided by members 5, 6 fastened to the members 3, 4, the chain having spaced depending pawls engageable with the hooks. At a working station along the bar 1 the chain pawls are disconnected from the hooks by being lifted above the bar 1 by a guide rail (8), Fig. 1 (not shown). As the carcases approach the working station they are driven at a greater speed than that of the chain 7 by an additional conveyor device including an inverted T-section rail 12 reciprocatable, in angle guides 18, 19 mounted on a U-sectioned member 17. The rail 12 has a bracket 11, Fig. 3, connected to the piston rod 10 of the piston of an elongated compressed air cylinder 9 and has spaced pins 13, 14, 15, 16 slidable on top of the bar 1. The member 17 is connected by brackets 20 to bearings 21 slidable on rods 22 extending transversely of the bar 1 and carried by a fixed frame supporting the members 3, 4. The member 17 is also connected by a link rod 37 with an arm 35 on a tubular shaft 27 rotatably mounted in fixed frame parts 23, 24 and parallel to the bar 1. Welded to the shaft 27 is a partitioned frame including rods 28, 29, 30, on which frame carcases are treated at the working station. The arm 35 is connected to the piston rod 36 of the piston of a compressed air cylinder 37 pivoted to a fixed frame portion 38. The piston rods 10, 36 are operated in timed relationship. When a pair of carcases are speedily delivered to the working station by the pins 13, 14 the piston rod 36 is operated to swing the partitioned frame to the position shown in dotted lines in Fig. 2, to support the two carcases and remain stationary for a working interval. At the same time the rail 12 and pins 13 to 16 are drawn away from the bar 1 so that the rail and pins can be retracted by the piston rod 10. After the latter is retracted the piston rod 36 is operated to return the parts to the full line positions in Fig. 2. The piston rod 10 is then extended so that the two treated carcases are moved away from the working station by the pins 15, 16 for continued movement along the bar 1 by the chain 7, and the pins 13, 14 move two more carcases to the work station. The cylinder 9 and piston 10 may be replaced by an endless chain operated step-wise.

Abstract: 993,100. Extruding plastic material. BAROGENICS Inc. Nov. 8, 1963 [Nov. 9, 1962], No. 44186/63. Heading B5A. [Also in Division B3] A workpiece 45 is deformed by fluid pressure acting directly or indirectly on the workpiece by first pressurizing the fluid to a primary pressure and then applying a transient secondary pressure produced by a shock wave to initiate the deformation. In an hydrostatic extrusion apparatus as described in Specification 942,642, a billet 45 surrounded by hydraulic fluid 46 is enclosed in a chamber 12 closed by a ram 35 carrying one or more extrusion dies 70, 71. The ram is moved upwardly to apply primary pressure to fluid 46, by a piston 25 in cylinder 17 supplied with hydraulic fluid through port 31. Secondary pressure to initiate extrusion is applied by a shock wave produced by a high-voltage discharge across electrodes 90, 91 connected to capacitors 102, transformer 103 and rectifier 104. The electrodes may alternatively be provided below piston 25 in cylinder 17. In another embodiment, Fig. 4, the billet 130 is extruded directly through die 126 by ram 135 connected to hydraulic piston 136. Primary fluid pressure is produced in chamber 137 by an hydraulic pump acting through conduit 140. The secondary pressure is produced by an explosive charge 145 detonated by a battery 151. Alternatively a thin wire may be exploded by a high-current pulse. U.S.A. Specification 3,063,594 also is referred to.

Steel-making plant comprises a row of regeneratively-fired open hearth furnaces 51 with one furnace replaced by a converter 120 tiltably mounted on a carriage 130 with trucks 155 running on rails 158 and having an exhaust hood 175 connected by conduits 176, 177 to the inlet ends 178 of regenerator chambers in the furnace exhaust system 55, conduit 176 being also connected by valve controlled conduits 181 to the firing ports of flanking open hearth furnaces 51. The exhaust hood also has a lance clamp 185 receiving a vertical oxygen lance 186 disposed between the hot metal crane 65 and the teeming crane 71. As shown in Fig. 3, the converter 120 straddles a trench in which is located a teeming ladle, the depth of said trench being such that the converter cannot be fully inverted over the ladle, Fig. 8 (not shown), but an electric switch is provided limiting the angle of tilt. Charging apparatus for the plant comprises a self-propelling car 200, Fig. 11, driven on trucks 203 on tracks 80 by a motor 204 and incorporating a platform 206 carrying a hopper 220 said platform being tilted about a pivot 207 by a segmental rack 208 meshing with a pinion 211. The bottom of the hopper is formed with steps 230, 231, 232 and 233 for the progressive discharge of scrap over a curved wall 260 into a transversely movable shoot 250 supported by a yoke 247 and propelled in a transverse notch 236 by a motor 243 through pinions 245 engaging racks 246 carried by the yoke 247. When used for charging the converter, Fig. 5 (not shown), the hopper 220 is loaded with fluxing materials as well as scrap to avoid having to provide additional flux charging devices. Use of the charging car 200 with the open hearth furnaces is facilitated by providing the latter with water-cooled doors 105 and door frames 100 extended partly over the side wall and partly over the roof, Fig. 12. Each door frame 100 comprises a closed motor-cooled loop 101 suspended by brackets 92a from roof beams 92 and supported on a refractory ledge 103. Each hollow water-cooled door 105 is lined internally with bricks 107 and suspended from an overhead box-formed arm 110 pivoted to a girder 112 carried by rear support columns 93 and actuated by a hoist 113 and cable 114. In a modification, Figs. 15-17 (not shown), the converter is tiltably mounted in a fixed position between the charging and teeming aisles straddling a transverse pit and has a removable exhaust hood mounted on wheels, being associated also with self-propelled ladle and slag pot cars. In all cases the converter is charged with molten pig-iron by ladles carried by an overhead hot metal crane above the charging aisle. Specification 1,006,546 is referred to.
