Title: Improvements relating to the feeding of pins, wires or the like
IPC: H01J9/46
Filed: 1945-04-03
Abstract: 591,510. Feeding pins by vacuum holding devices. MITCHELL, W. B. April 3, 1945, No. 8231. [Class 117] Means for feeding and depositing pins, wires or the like comprises a magazine for the pins and a suction nozzle which have relative movement so that the nozzle may be brought into engagement with, or adjacent to, the exposed ends of the pins and a pin caused to adhere thereto by suction, the nozzle being then removed from the magazine before release of the pin by interruption of the suction. The invention is described as applied to the feeding of electrode wires to passages in a mould, in the manufacture of radio valve bases. As shown, a magazine 3 provided with a number of bores for holding wires side by side, is secured detachably to a T-shaped member 5 which is adapted to be vibrated rapidly by an electromagnet 11, so that the wires are maintained in properly piled condition in the magazine. Suction nozzles 19 are mounted in a fitting 20 rotatably mounted on arms 14 which are oscillated by a reciprocating rod 15, so that the nozzles are brought adjacent the bores of the magazine 3. A cam bar 13 controls the movement of the nozzles about a spindle 21. The arrangement is such that each nozzle 19 is brought into engagement with the end of a wire in the magazine, holds the wire by suction, removes it to a position above a funnel 25, and drops it into the funnel on interruption of the suction. The funnels have depending tubes 26 which are bent so that the lower ends form a circular series arranged above a series of funnels 28a communicating with bores 28 in a loading block 27. The bores are spaced correspondingly to passages in a mould 29. The mould is one of a number carried by a table which is rotated intermittently to bring each mould beneath the block 27. The block is vibrated rapidly by means of an electromagnet to assist the insertion of the pins in the mould passages. The pins must be inserted in the passages with their larger ends downwardly. In the event of them being picked up by the suction nozzles with the larger ends uppermost, they are tilted by deflecting means 30a so that they fall in the correct position into the funnels 25. The pins are clear of the deflecting means if they are picked up in the correct position, since the smaller end of the pin enters the suction nozzle.

Filed: 1975-02-28
Abstract: 1491751 Filter press plates and frames STATNI VYZKUMNY USTAV MATERIALU 28 Feb 1975 8412/75 Heading B1D Filter press plates or frames are injection moulded of polyethylene, polyurethane or polypropylene so that their surface zones are of higher density than their internal zones (Figs. 1, 2 not shown). The plastics may include up to 75% of a filler such as fibres or glass beads. In manufacture a blowing agent is added to give the internal zones a cellular structure, but the surface zones are non-cellular, either because they cool too rapidly to expand on contacting the mould walls or because the surface zones are formed by a first injection of plastics without blowing agent before the blowing agent-loaded plastics is injected to form the internal zones. Fig. 4 shows a frame with a central cylindrical support 23 adapted to bear on adjacent plates in use and having ends coplanar with main faces (7). Inclined surface 8 facilitates cake discharge, slurry inlet passages 9 are flared and recesses 20 extending from the outer edge reduce weight. Frame or plate supports 11 (Fig. 5) may be welded to projections 10 or are formed integrally with the frame or plate. The bearing surfaces of supports 11 are protected by replaceable polyformaldehyde covers 15 which slide on in dovetail manner (Fig. 6 not shown).

Title: Improvements in or relating to billet loading apparatus
IPC: B21C33/00
Filed: 1962-03-07
Abstract: 931,931. Extruding. BALDWIN-LIMA-HAMILTON CORPORATION. March 7, 1962 [March 22, 1961], No. 8719/62. Class 83 (4). A billet loading apparatus, particularly for an extrusion or piercing press, comprises a carrier 50 movable by an actuator 32 from an initial billet receiving position 110 to a charging position 130 and having pivotally mounted thereon about an axis 70 perpendicular to the billet axis, a billet support 80 which is movable from an erected billet-supporting position, Fig. 3, into a collapsed position, Fig. 6 (not shown). The billets 120 roll down a shoot 114 to the position 110 where they rest in a trough 82 of the support arms 80 which are then held in a horizontal position, Fig. 3, by a fluid motor 84 acting through a pivoted link 90. A double-acting fluid motor 32 then moves the carrier 50 about its pivots 44, 46 into the charging position 130 where the billet is aligned with the container bore 132. Extrusion stem 15 acting through dummy block 122 then pushes the billet into the container bore and during the extrusion a roller 100 on the stem holder 18 engages the ends 96 of the support arm and collapses them in a vertical position, Fig. 6 (not shown). The motor 84 may also be double-acting and controlled by valves to collapse the arms before they are engaged by the follower 100. In another embodiment, Fig. 7, the carrier 150 is mounted on a single pivot 152 and actuated by motor 156. The billet support 180 is actuated by a toggle linkage 202, 204, Fig. 9, and is raised automatically when in the receiving position 110 by a spring 220 acting through cable 224. During extrusion a cam 240 on the stem holder 18 engages a roller follower 250 secured to toggle arm 202, thereby collapsing the toggle. Finally a roller follower 100 moves the billet support into a substantially vertical position, Fig. 6 (not shown). In this embodiment the container housing 140 with the carrier is movable axially of the press. A projection 190, Fig. 9, on the carrier co-operates with a fixed projection 192 on the container to support a cleaning disc 270, Fig. 11 (not shown), which is pushed by the stem through the container bore.

Title: Improvements in or relating to power door operating systems
IPC: E05F15/02
Filed: 1954-03-25
Abstract: 753,129. Door-operating apparatus. NATIONAL PNEUMATIC CO., Inc. March 25, 1954 [Dec. 1, 1953], No. 8733/54. Class 65 (1). An hydraulic door engine for vehicle doors, supplied with fluid under pressure from a motordriven pump through a control valve for opening and closing, is also connected to an accumulator when the valve is in the door-closing position so that any manual opening of a door forces fluid into the accumulator and as soon as the door is released it is re-closed by the pressure in the accumulator. In the arrangement shown, the pump 22 draws fluid from a reservoir 24 (to which it has a relief by-pass 60) and delivers it to an accumulator 16 (with which is associated a pressure-sensitive pump-controlling switch 18) and a valve 10 which may be operated electrically, pneumatically, hydraulically, or by hand. The valve 10 in one position connects the accumulator and pump to the left-hand end of the door-engine 8 and the other end of the engine to the reservoir through pipe 52, to open the door, and in the other position reverses the connections to close it; the passage 44 is restricted, to reduce the closing speed by throttling the exhaust, but is by-passed to allow free opening by a one-way valve 66. The door can be opened manually against the pressure applied by the accumulator, and this pressure will re-close the door as soon as it is released. If the passage 44 is large enough to allow free opening the passage with the valve 66 may be omitted. In a modification, Fig. 3 (not shown), a differential engine is used, and the accumulator is incorporated in it at the small (door-closing) end, the valve 10 controlling the other end only. The passage 44 is made of full size, and the closing of the door is checked by a restriction placed on the supply side of the valve 10. A power unit comprising all the hydraulic system in a compact assembly is described (Fig. 1, not shown), the engine actuating a rack engaging a toothed-sector on a shaft carrying a door-operating arm; the end of the sector meets a stop when the doors are open.
