Title: Improvements in or relating to machine tools
Inventor: RADFORD WILLIAM EDWARD ADRIAN
IPC: B23Q5/26
Filed: 1958-05-12
Abstract: 902,037. Drilling long holes. ENGINEERING RESEARCH & APPLICATION Ltd. May 12, 1959 [May 12, 1958], No. 15142/58. Class 83 (3). A machine tool comprises means for controlling a series of advance movements of a tool-holder in which a series of projections carried by a movable device sequentially effect return movements of the holder, which movements operate means to index the projections. An electric motor 10 rotates a splined shaft 11 along which a spindle 12 in a quill 14 may be advanced by two diametrically-opposite piston rods 41. The quill carries a cross-head 60 moving on diametrically opposite guide rods 64, 65 and carrying a platform 68 mounting a carrier 69 having stops 70, 75. The rods 41 are pneumatically-operated in unison by a valve which is reversed by the stop 70 actuating a switch through a lever 71 at the forward end of each stroke. A further switch is operated by the stop 75 and a lever 73, when the rods have been retracted, to cause a further advance movement. Also attached to the cross-head is an hydraulic ram 110, Fig. 2, in a system which controls the feed-speed by allowing fluid to pass through ports 120 or 121 to either of adjustable valves 123, 124 or to an unrestricted port 119. A valve 126 is opened or closed to allow the retraction speed to be at a faster rate, or at the feed rate when tapping is in progress. Air pressure behind a piston 129 maintains the fluid system at the required pressure. The piston 129 carries a visual indicator to denote when the system should be replenished with oil through a valve 131 to make-good leakage. The valve controlling ports 119, 120, 121 is actuated by a camtrack or cams 131, 132, 133 on the cross-head 69, which cams engage a roller 134 on a lever 135. The means of the invention for controlling a series of advance movements comprises two sets of stops 252, 256, Fig. 11, which are mounted in place of the stops 70, 75. They are indexed by a ratchet operated by a lever 267 oscillated on each forward movement of the drill by a fixed cam 271. The stops 252 are successively shorter to permit the drill to advance in steps, the lengths of the stops 256 determining the lengths of the withdrawal movements. When the operations are complete, a dog is operated to release a holding pawl and allow a spring to return the stops to their initial positions.

Title: Apparatus for removing sheets of material from a stack of material
IPC: B65H3/46
Filed: 1957-05-15
Abstract: 827,893. Feeding sheets. LUBER-FINER Inc. May 15, 1957 [Aug. 27, 1956], No. 15398/57. Class 100(1) Apparatus for separating sheets from the top of a pile 17 comprises a suction nozzle 30 mounted retractably on a fixed mount 11, and stationary needles 38 arranged either above the uppermost sheet or so that they impale several of the top sheets, the nozzle being lowered relatively to the mount 11 preferably under the action of a spring 32, until it engages the top sheet, whereupon suction builds up in the nozzle and it is raised with the top sheet which is impaled by the needles 38. As shown, the mount 11 is a tube 20 supported in a frame 10 and connected to a source of suction. The nozzle 30 forms part of a tube 21 mounted on the tube 20. Pins 24, 25 on the tube 20 engage slots in the tube 21 to prevent relative rotation and act as stops, and the spring 32 is arranged between these stops and a washer 31 on the tube 21. The nozzle is formed by flattening the tube 21 at the lower open end. In a modification the nozzle 30 is separate, and joined to the tube mount 20 by a bellows connection. There are two identical needle carriers 12, 13, positioned one on each side of the nozzle 30, secured to the frame 10. Each needle is carried in a plug 37 which is retained in a fixed collar 36 and urged outwardly thereof by a spring. When a sheet is raised from the pile, a blast of compressed air from a nozzle 52 floats the sheet into contact with a rotating suction cylinder 15 which grips the sheet and feeds it away from the pile, tearing the sheet from the needles 38 and overcoming the suction of the nozzle 30. When the sheet is thus removed from the nozzle, the latter can be moved down on the pile by the spring 32, and the cycle is repeated automatically.

Hydrogen sulphide is removed from coal gas &c. during passage upwardly through purifier towers charged throughout the whole cross-section of the tower with pelleted material, e.g. hydrated iron oxide, cement, and a filler, which passes completely through without being subjected to intermittent oxidation portions being withdrawn at the bottom intermittently or continuously and revivified while the charge sags down under its gravity, fresh or sulphur-freed material or mixtures being fed in at the top. A plant comprising four units in parallel, includes two purifiers 11, 13, in series in each unit. A portion of fouled material from the first tower of each unit is revivified each day in a tank 16 by air circulated by a fan 17, the heat of reaction being dissipated in a scrubber 18. The material is returned to the purifiers until an elementary sulphur content of 40- 50 per cent is reached when it is replaced by material from the second towers of the units, which hitherto has been returned after revivification to the second towers. These are then fed with raw material or revivified material from the first towers treated with a sulphur-removing solvent. The process or a final stage may be operated under pressure.
