Title: Improvements in or relating to machines for and methods of bending tubes
IPC: B21D7/00
Filed: 1958-12-29
Abstract: 903,695. Angular bending. PRECISION AIRCRAFT (READING) Ltd., and PALLANT, W. March 18, 1960 [Dec. 29, 1958], No. 41898/58. Class 83 (4). A method of bending a tube comprises applying a bending moment to the tube and rolling the wall of the tube in a circumferential direction to re-distribute the material of the wall between the inside and outside of the bend. A tube 48 to be bent is clamped at one end between an internal split disc 49 expanded by a conical pin 50 and an outer ring 52, the clamping means being carried by a bracket 47 adjustable along a beam 46 on a machine base 10. Three adjustable rollers 25 surround and engage the tube 48 and are carried by a cage 21 rotated around the tube by a motor 30, supported on bearings in a bearer structure including two plates 27. This structure is adjustable by a lead screw 32 along bars 15, 16, 17, 18, connected at their ends by plates 13, 14 to form a jib 12 swingable about a pivot 11. A disc 45 supporting the tube 48 internally against the rollers 25 is supported by a rod 44 on which is mounted a second tube support disc 53, the rod 44 being carried by a beam 42 extending from the bearer structure 27 and adjusted so as to be at right angles to the bars 15-18. In operation the jib 12 is moved about its pivot 11 by a pinion 36 engaging a fixed arcuate rack 37 and driven by a hand wheel 39 or from the motor 30 so that the rollers, as they rotate around the tube 48, move slowly therealong to impart a bending moment on the tube and at the same time move metal from the inside to the outside of the bend. To produce tubes bent about more than one axis the table 10 may be rotatable about an axis at right angles to the pivot 11, the beam 46 being adjustably secured to a fixed part of the machine instead of to the table.

Abstract: 1275630 Explosive forming H HERTEL 25 Aug 1969 [25 Sept 1968] 42311/69 Heading B3Q Apparatus for forming workpieces 8 against a die 6, Fig. 1, in a closed chamber 1 by shock waves in a liquid comprises a forming chamber consisting of elements at least one of which is moved by the shaping pressure to vent the chamber, and a further chamber 14 having an opening into the forming chamber and another for insertion of means 15 to produce the shock waves, the latter opening being closed, in use, by inertial forces. In the first form, the forming chamber consists of a side wall 2, a top wall 3 containing the further chamber 14 for an explosive cartridge 15, and the die 6 carried by a member 5 which is supported on rubber blocks 11. A cover plate 4 carrying a firing pin 16 is slidable into position in a yoke 10 supporting the chamber. A flexible membrane 19 covers the work 8 and, upon firing the cartridge, the top wall is forced against the cover plate 4 which, due to its inertia, holds the top of the cartridge chamber 14 closed. The forming chamber is vented over the top of wall 2. In another construction, Fig. 2, the cartridge chamber 24 is closed by a plate 4<SP>1</SP> containing a firing mechanism 27, and a catch 31, connected to the plate 4<SP>1</SP> by a spring 32, retains the plate in a raised position after the cartridge 15 is fired. Bolts 26 suspend the top mass 22 of the chamber from the plate 4<SP>1</SP> and allow it to fall a certain amount for removal of the cartridge chamber 24 or automatic ejection of a cartridge case. Rods 28 guide the mass 22 and a lower mass 23 which is supported on springs 30 and damped by shock absorbers 33. In a further form, Fig. 3 (not shown), the cartridge chamber (14<SP>1</SP>) is within the forming chamber (1) which is retained in a raised position by a catch (31) for downward loading movement of the cartridge chamber by an hydraulic cylinder (36), which may eject the spent cartridge. The cartridge chamber may be rotatable, on a bearing (38). A modification of this construction includes separate guide rods (28<SP>1</SP>, 28<SP>11</SP>) for the top and bottom masses (22<SP>1</SP>, 23) and a cartridge chamber (14<SP>11</SP>) mounted on the top rods (28<SP>11</SP>). Specification 1,275,628 is referred to.

An apparatus for continuously carrying out chemical reactions in a glow discharge under reduced pressure comprises a plurality of concentric coaxial hollow cylinders 1 electrically insulated from one another, the spaces between the hollow cylinders being alternately a discharge space or spaces 14 and containing a heating or cooling medium 15 and being closed at both ends in a gas and liquid-tight manner by lids 2, 3 held together by bolts 6 reaching from one lid to the other, the lids 2, 3 serving as electrode supports and supports for the inlet nozzles 7 for the gas and/or vapour to be treated and the outlet nozzles 9 through which the treated gas and/or vapour issues and both lids 2, 3 having means for the introduction and the issue of the cooling or heating medium. The electrodes 11 and nozzles 7, 9 are arranged in a ring or rings of equal radius or radii. The gas and/or vapour is supplied by a distributer 8 and the treated gas and/or vapour removed by a collecting vessel 10. The inlet nozzles 7 have openings at the side to introduce the gas and/or vapour tangentially so that the gas flows helically. The outlet nozzles 9 have lateral or slant openings. The electrodes 11 are axially movable and are held in non-conducting jackets held by rubber stoppers. Additional annular discharge spaces may be provided. The device may be used for the manufacture of HCN from hydrocarbons and N 2  or NH 3 ; nitric oxides from air; 0 3  from O 2 ; or hydrazine from ammonia. The walls of the discharge spaces may be coated with catalytic material. The electrodes may be energized by D.C. or A.C. If the cylinders 1 are of metal they may be coated with enamel or synthetic plastic material which may have a layer of electroluminescent phosphor. If the cylinders 1 are of glass or ceramic lids 2, 3 are of metal. The electrodes may have an insulating coating of a high dielectric constant. Bimetal switches are provided for the electrodes.

Title: Singeing Device for Yarn produced by a Two-for-One Twisting Spindle
IPC: D06B21/00
Filed: 1967-09-25
Abstract: 1,192,590. Singeing yarns. PALITEX-PROJECT CO. G.m.b.H. 25 Sept., 1967 (25 March, 1967], No. 43480/67. Headings D1D and D1F. In a singeing device comprising a heated cylinder located at the balloon apex of a two for one twisting machine, the cylinder is smooth inside, is of a highly heat resistant material and is heated by an external element surrounded by a protective jacket, an air supply conduit opening into the yarn inlet end of the cylinder. The cylinder preferably is of quartz glass or ceramic material. In Fig. 3 the cylinder 13 is within a tube 14, the intervening space being exhausted the heating coil is supported by hooks 16 and a pipe conducts air which may be enriched with oxygen to the bottom of the tube to ensure that the yarn is effectively singed. The device is within a housing 18 with insulating plates 17 and screw-cover 20 and mounted on a plate 12 which screens the device. In passing through cylinder 13 the yarn makes a second balloon and thus wipes the surface of the heater. In Fig., not shown, the tube 13 has grooves to support the element and is surrounded by a heat-reflecting surface (24). The tube may taper (Fig. 7, not shown) to improve the contact of the yarn with the inside of the tube. In Figs. 8, 9 (not shown) 'the inner tube may be constituted by a re-entrant portion of the outer cylinder. A threading slot which may have guide-plates on either side of it is thus provided through which the yarn may be easily threaded and removed, it being thus unnecessary to switch off the heat when the yarn is stationary. In Fig. 11 the device is in two halves which can be rocked about pins 32, 33 to close or separate them; to this end one of the halves is connected to the armature of a solenoid 39 and the two halves are operatively interconnected by meshing teeth at 36. The solenoid may be controlled by the movement of the yarn, so that the two halves are separted when the yarn is stationary, thus making it unnecessary to switch off the heat between operations.
