Title: Method and apparatus for feeding billets to an extrusion press
IPC: B21C33/00
Filed: 1975-07-09
Abstract: 1463020 Feeding billets for extrusion SCHLOEMANN-SIEMAG AG 9 July 1975 [19 July 1974] 28861/75 Heading B3P Apparatus for feeding billets comprising two billet parts from a hot billet shear to an extrusion press comprises a conveyer A for picking up the billet parts, means moving the conveyer towards the extrusion press, the means being so arranged that on reaching the extrusion press the billet part that entered the shear first lies behind the billet part that entered the shear second, in the extrusion direction. Billets 5 are cut to length from heated aluminium bar by a first fixed shear part (not shown) and a movable shear part 3, and when the last full length billet has been cut from the bar, the portion remaining is advanced through the shear until it reaches a stop. A new length of heated bar is fed through the shear until it abuts the remaining portion of the previous bar and the shear is then operated. The billet parts are held in grippers 14 of the conveyer A and when the grippers are raised an hydraulic device 10 is actuated to move the conveyer leftward as seen in Fig. 1. When in position a rack (19), Fig. 2 (not shown), is actuated to engage a gear (20) and to rotate the grippers through 180 degrees. This allows the cooler billet portion to enter the extrusion press first so that a better weld is formed between the billet portions. When single billet portions are fed to the press, the grippers are not rotated.

Abstract: 967,963. Discharge apparatus. NATIONAL INSTITUTE FOR RESEARCH IN NUCLEAR SCIENCE, and UNITED KINGDOM ATOMIC AUTHORITY. Aug. 7, 1962 [Aug. 11, 1961],  No. 29159/61. Heading H1D. In a D.C. particle accelera-  tor to prevent spuriously produced electrons from receiving the full acceleration voltage and thereby producing X-rays of high energy, a group E30-E63 of the generally plate- or dish-shaped electrodes of the accelerator are arranged with their planar portions tilted at an angle approximately 10 degrees, to the transverse plane, the direction of tilt of successive electrodes being changed incrementally in azimuth to follow a pattern of at least one pair of oppositely-directed 360 degrees spirals. Locally emitted electrons, which have initial velocities much smaller than those in the primary particle beam, will thus follow oblique directions to encounter neighbouring electrodes before their energy is sufficiently high for X-ray production. The spiral arrangement ensures that the sum angular deviation of the particle beam is zero while the provision of a pair of oppositely-directed spirals cancels the effects of linear displacement of the beam axis. In general, for optimum conditions, the rate of spiralling (i.e. the increment of azimuthal angle) is larger the smaller the particle velocity. Because of the change in velocity of the particles the angular increment is decreased proceeding along the tube. The Specification gives formulµ and a table for calculating the azimuthal angle.

Abstract: 722,609. Stuffing-box substitutes. JENDRASSIK, G. Nov. 28, 1952 [Dec. 13, 1951], No. 29279/51. Class 122 (5). [Also in Groups XIII and XXVIII] An end-plate structure required to be maintained in closely spaced relation to a machine component with relative rotation there between, despite alterations in dimensions along the rotational axis by the component includes an axial extension of the end plate radially beyond the component and guiding devices on the extension to counteract tilting tendencies of the end plate. End plates 5, 13 of a rotary pressure exchanger having labyrinth seals 9 are maintained in close spaced relationship with a cell wheel 3 by means of the bearings 8 and have cylindrical axial extensions 10 radially beyond the cell wheel 3, liaving mating keys 11 and keyways 12 formed thereon at spaced intervals around the periphery in two separate transverse planes perpendicular to the axis of rotation, which prevent tilting of the end plates. Seal rings 19 are provided between the extensions 10. The cell wheel 3 is surrounded by a cylinder 14, which may be split for assembly, co-operating with seal rings 15 carried on further axial extensions 17 from the end plates. In another construction, Fig. 5, the extensions 10 are replaced by members having interengaging fingers 30, the tips 31 of the fingers on one member cooperating with the base between the adjacent fingers of the other member. The Specification describes several co-operating devices which may be secured to the tips and bases to ensure guiding while permitting axial movement between the end plates. In a further construction, Fig. 20 (not shown) an axial extension on one end plate carries axially and circumferentially spaced devices which co-operate with devices carried on a surrounding member carried by the frame of the machine. In a further construction, Fig. 22 (not shown), similar to that shown in Fig. 1, extensions from the end plates have rims which co-operate with the peripheral surfaces on the opposite end plate. In a still further construction, Fig. 18 (not shown), an end plate has axial extensions on both sides and these extensions each have circumferentially spaced devices which cooperate with devices on a fixed member. Pressure balancing devices may be fitted to the axial extension, one such device being shown in Fig. 5 and comprise pressure cylinders 21 on one extension, the pistons of which are connected by links and levers to the other extension. The invention is stated to be applicable to rotary heat exchangers. Specification 678,218, [Group XXVIII], is referred to.

Abstract: 912,468. Gear-cutting. WICKMAN, A. C. Sept. 27, 1961 [Aug. 26, 1960], No. 29496/60. Class 83 (3). A gear-hobbing machine comprises means for relatively feeding a cylindrical blank 10, Fig. 1, at right-angles to its axis and obliquely to the axis of a grinding hob A, the helix angle of the hob being such that the ribs engaging the blank are parallel to the axial or helical teeth of the blank and rotate the blank during the feeding movement. The teeth are ground progressively from the bottom 10a to the top 10b of the teeth as the gear is fed. The hob may be of multistart form. In a modification, two hobs A, B are fed from the positions shown in Fig. 5 to those of Fig. 6, the hob A being above the blank and the other below it. Instead of feeding both hobs, the blank and one hob may be moved. In a further modification, the blank 10, Fig. 14, is fed between two oppositely-rotating hobs A, B, the teeth being ground from bottom to top by one hob and from top to bottom by the other hob. One side of each hob may thus roughgrind the teeth (and may be tapered at the entry end) and the other side finish-grind them. The hobs are rotated by electric motors 22 or may be driven by a single motor through differential gearing. One hob is driven through a one-way clutch and the hobs are driven at the same speeds until they have engaged the blank. One hob is then driven at an increased speed to cause feed of the blank. The hobs may be barrelled to produce crowned teeth. The hobs have diameters up to 10 times the diameter of the blank and an axial length equal to the diameter of a blank or of the diameters of two blanks if two gears are to be produced side-byside.
