Title: Improvements in and relating to Draw Benches for Tubes and the like.
IPC: B21C1/30
Filed: 1917-09-29
Abstract: 118,491. Everitt & Sons, A., and Barnsley, F. H. Sept. 29, 1917. Drawing; separating mandrels from work.- Draw-benches for tubes and the like, of the kind described in Specification 117,328, are modified by arranging for the dies to traverse a fixed mandrel which is held by a fixed holder while the drawing-die moves, and the other end is held by an adjustable holder while the stripping-die is in operation. The drawing-die e and stripping-die f are carried by a counterbalanced chain g passing over a pulley h, and the required die ;s brought into operative position on one side of a thrust block m, the whole being carried by a wagon t on chains b which move over channels a<2> of the bed a provided with a central channel a<1> for the wagon t. As the drawing-die moves to the right, Fig. 1, the mandrel is held by a fixed holder at the left of the bench, and on completion of the draw, the mandrel is held by an adjustable holder at its right end, the stripping-die being first brought into position. The motion of the chains b is then reversed.

Inventor: DURRANT ALBERT WILLIAM
IPC: F23D11/10
Filed: 1962-04-12
Abstract: 1,045,141. Atomizing burners. BRITISH IRON & STEEL RESEARCH ASSOCIATION. July 10, 1963 [April 12, 1962], No. 14155/62. Heading F4T. An atomizing burner comprises a shell and a movable slug disposed in a bore of the shell to define a passage for carrier fluid which passage is so contoured as to impart a uniform acceleration to fluid passing therethrough, liquid fuel being injected into the carrier fluid prior to or at the entry thereof into said passage. In the embodiment shown in Fig. 3, the passage is first convergent and then of uniform cross-section and the slug 13 is coupled to a pair of concentric tubes 14, 15 separated by an air space, the tube 15 supplying oil to passages 17, 19 in the slug. The shell 10 is carried by a pipe 11 which is supplied with carrier fluid. The tube 14 is slidably received by nuts 24, 25 between which is a resilient ring 26. A non-return oil valve 18 is disposed within the slug 13. In another embodiment, Fig. 1 (not shown), the passage for carrier fluid is first convergent and then divergent, and axial movement of the slug in the shell produces a change in the cross-sectional area of the throat which produces a change in the same sense of the cross-sectional area of the exit from the divergent part of the passage. In a further embodiment, Fig. 2 (not shown), the shell has a divergent internal surface to the downstream and the slug has a divergent external surface to the downstream.

Abstract: 911,694. Laminates. DUNLOP RUBBER CO. Ltd. April 24, 1959 [May 3, 1958], No. 14183/58. Class 140. Flexible films of polyamides or non-vinyl polyester resins, e.g. polyethylene terephthalate, are bonded together under heat and pressure by the use between them of an open plain-weave fabric and a heat-activatable adhesive such as polyvinyl chloride paste. The fabric preferably has a mesh size between 4 and 30 X 10-<SP>4</SP> sq. in., and may be of cotton, linen, wool, rayon, or synthetic fibres; examples are cheese cloth and butter muslin. The fabric may be coated with adhesive and sorted until required. The films used may be drawn longitudinally or both longitudinally and, preferably to a lesser extent, laterally, may be roughened, e.g. by sand blasting, before bonding, and may be precoated with a polyisocyanate such as triphenyl methane triisocyanate or naphthalene 1,5-diisocyanate in a solvent, such as methyl ethyl ketone subsequently removed. The products may be incorporated in printers' blankets, valve diaphragms, or power-transmission or conveyer belting, the latter comprising multiple layers of alternate composite film and fabric and having rubber, polyvinyl chloride or other outer layers secured with P.V.C. paste.

Abstract: 580,757. Welding. MARTIN, H. Nov. 10, 1942, No. 14975/44. Divided out of 580,732. [Class 83 (iv)] In welding metal or alloy studs, tubes or the like to plates or other bodies, particularly for welding studs of steel or alloys thereof-to plates of steel or alloys thereof, the end of the stud &c. is metallised with a metal of high electrical conductivity such as aluminium, an arc is struck between the stud &c. and the plate, the sttid &c. moved into contact with the plate and the current maintained until the weld is completed. Direct or alternating current may be used. The metallisation of the stud &c. causes an instantaneous uniform arc to be formed. The arc may be formed by with drawing the stud &c. from contact with the plate, by bridging a gap between the stud &c. and plate with a fusible mass such as a ball of fibrous metallic material, or by a short length of metal tube or a pin of small cross-section. Metallising is effected by metal spraying, preferably by the Schori or Schoop process. The stud may have a coned end and an adjacent part for a distance, e.g. of “" unthreaded and the coned part and, if desired, also the unthreaded part may be metallised.

In an axial-flow fan according to the parent Specification, the pivotal connection between a blade and the hub or between the inner and outer parts of a blade comprises a universal joint permitting movement of the blade or the outer part about axes transverse to a radius of the fan, and each blade is so secured to a part of its joint as to be adjustable about a longitudinal axis of the blade, and means are provided for clamping the blade to the part of the joint in an adjusted position. In the fan shown in Fig. 1, each blade 37 is carried by a shoe 36 having a threaded stem 35 to which a ball 25 is clamped by a nut 39. Each ball 25 is located in a spherical socket formed in the two parts 10, 11 of the impeller hub so that the blade 37 can tilt about any axis at right-angles to a radius of the fan, rotation about the radial axis being prevented by pegs 27, 28 which engage a circumferential groove 26 in the ball. The amount of tilt is limited by a cylindrical socket 40 which surrounds the end of the stem 35. In a modification, Fig. 3, the ball 25 is replaced by a block 46 pivoted on trunnions 44 in a gimbal ring 43 which in turn is pivoted on trunnions 48. Fig. 4 shows a construction in which the universal movement is provided by a rubber ring 56 bonded to the conical faces of a blade-carrying member 54 and a socket 50. The holes in the rim of the hub which receive the attachment bolts for the socket 50 may be slotted to permit the socket to be rotatably adjusted about a radius. In a modification, the rubber mounting is disposed at the radially inner end of the blade stem, and the socket 40 is omitted, limitation of movement being provided in this case by the clearance between the blade stem and a hole in the hub rim through which the stem projects.
