Title: Methods and apparatus for swaging and relieving stresses in and straightening tubular workpieces
IPC: B21C1/26
Filed: 1959-02-02
Abstract: 882,914. Swaging. APPEL PROCESS Ltd. Feb. 2, 1959 [April 25, 1958], No. 3544/59. Class 83 (4). An elongated tubular workpiece 26 is swaged over a mandrel 30 by radially acting dies 20 and the leading end 43 of the workpiece leaving the die throat 27 is supported during its forward movement at two longitudinally spaced points 50, 52 for keeping the workpiece straight and relieved of stress. The swaging machine is preferably of the kind described in Specification 797,518 and the workpiece 26 gripped in a chuck 26 is fed incrementally through the dies which act out of phase with the feed movements. The leading end 43 is received in a counterbore 41 of a support tube 42 slidable within a fixed outer tube 40 and over two spaced shoulders 50, 52 on a forward extention 48 of the mandrel. The tube 42 may be yieldably biased in opposition to forward movement. As swaging proceeds the support tube 42 is ejected from the outer tube 40 and the swaged workpiece is then supported solely by the shoulders 50, 52, Fig. 3 (not shown).

Title: Improvements in or relating to preformed composite beams for floors, roofs and ceilings
IPC: E04C3/22
Filed: 1936-02-06
Abstract: 469,680. Reinforced-concrete beams; hollow blocks. MORTON, B. Feb. 6, 1936, No. 3592. [Classes 20 (iv) and 87 (i)] A preformed beam for floors, roofs, and ceilings is made by aligning hollow blocks a, each of which has partitions b forming a number ot chambers c<1>, c<2>, c<3> and one or more slots d in the upper wall through which concrete is poured to fill any one or more of the chambers. Reinforcing rods e are inserted into the chambers into which the concrete is to be poured, the rods being supported by wires bent over the sides of the slots d or over bridge pieces b<1> at the ends of the slots d. The end blocks for the beam are closed at one end. The blocks may be formed with a projection a at one side and a corresponding recess at the other so that the assembled beams may interengage to form a floor, and one or both sides of the blocks may be inclined to leave a space into which concrete may be filled. The sides of the blocks may be extended upwardly, to form a trough on the upper side of the beam, which is filled with concrete, or wooden shuttering may be applied to the sides of the blocks to form a trough. Additional slots may be provided in the upper wall of selected blocks, e.g. the end blocks of the beam, particularly where beams are laid end to end, so that concrete may be run into other chambers of such end blocks after the beams have been positioned, in order to unite the beams end to end. The chambers into which the extra concrete is run, are closed at the end farthest from the beam end. Slots d may also be formed in the bottom surfaces of the chambers c<1>. . . to constitute additional keying for the concrete. If the blocks are made of concrete, the outer walls may be reinforced with metal or fabric, moulded therein. Beams may be connected end to end by right- and left-hand threaded sleeves engaging screwed projecting ends of the reinforcing bars.

Abstract: 475,178. Automatic guns. SCHWARZLOSE, A. W., SCHWARZLOSE, W., and LUNDBERG & CO., V. Feb. 6, 1936, Nos. 3693 and 3694. Void. Convention dates, July 1, 1935 and Dec. 21, 1935. [Class 92 (ii)] Relates to gas-operated guns in which the gases escaping at the gun muzzle are utilized to check recoil and to operate the gas piston. According to the invention, the gases leaving the muzzle enter an expansion chamber 8, Fig. 1, and passing through a curved passage 13 are gradually reversed in direction thereby exerting a forward reaction on the gun to check recoil, a further reversal of direction taking place as the gases pass round turbine like surfaces 15 and react on the gas piston 17 before they finally escape forwardly through openings 20. The action of the gases takes place while the projectile traverses the muzzle extension 9, the gases being divided into two streams by surfaces 12 converging to a sharp edge 10. Fig. 3 shows a modification in which the parts are carried by a casing 19 ball jointed at 29 to the barrel the gas piston 17 sliding on the barrel and being connected by a rod 18 to the breech mechanism. Two sets of reaction surfaces 12, 25 check the recoil and the corresponding surfaces 15, 26 in the gas-escape passages from the reaction surfaces on the piston. The form shown in Fig. 1 may have two sets of reaction surfaces 15, 26 on the piston as shown in Fig. 4. Fig. 7 shows a modification in which the piston 17 acts on the breech-operating member 18 through a lever 35.

Title: Method of etching semiconducting material, especially germanium and silicon
IPC: H03K3/313
Filed: 1954-02-12
Abstract: In a method of cleaning by etching semiconductor materials such as silicon, that part of the surface to be etched is heated, preferably to 100 DEG C., and simultaneously exposed to the action of a gas which combines with the heated portion to form a volatile compound. Suitable gases are chlorine and the hydrogen halide and the volatile compounds produced may be later removed by volatilization.  The process may also be used to change the shape of a crystal, to cut it in two and to make a hole through it.  For these purposes the area of impingement of the gas on the crystal is preferably controlled by a suitably shaped nozzle; the nozzle may also be used as an electrode, when it is preferably made of graphite, for providing electrical heating of the semiconductor thus also obtaining, if desired, a local heating effect.ALSO:In a method of cleaning by etching semi-conductor materials such as germanium and silicon, that part of the surface to be etched is heated, preferably to 100 DEG C., and simultaneously exposed to the action of a gas which combines with the heated portion to form a volatile compound.

Abstract: 128,874. Mathy, M. Feb. 22, 1919. Tilting crucible furnaces; covers.-The tilting- mechanism of a crucible furnace is so arranged that the removable cover serves to counterbalance the weight of the furnace during the tilting operation. The cover 5 is removed from the furnace by tilting it into a vertical plane as shown in Fig. 2, and in this position its entire weight is carried by brackets 9, which slide on vertical standards 10, and are connected by links 11 to levers 7, in turn connected to the furnace by links 21. The movement of the cover is facilitated by a balance weight 16, and pinions 13 on the tilting-axis 12, engaging with racks 14 on the brackets 9, ensure that the cover is moved clear of the furnace. The levers 7 are operated by a hand-wheel 17 and screwed shaft 18. The furnace is heated by the flameless combustion of gas and air in a mass of refractory material, and the products pass through a helical flue 25 in the casing to the outlet flue 27 when the furnace is in a vertical position. The air for combustion is supplied through one of the trunnions and is heated in a second helical flue 29. To prevent choking of the gas and air mixing-chamber 32 by metal from a broken crucible, the opening at the bottom of the furnace is closed by a plate 34 oi material having a lower melting-point than that of the material under treatment.
