Title: Apparatus for producing corrugated weld-seamed metal tubes
IPC: B23K31/02
Filed: 1958-08-19
Abstract: 893,552. Making corrugated cable sheaths; welding by fusion; bending; corrugating. HACKETHAL - DRAHT - UND KABEL-WERKE A.G. Aug. 19, 1958 [Aug. 19, 1957], No. 26691/58. Classes 83 (2) and 38 (4). Apparatus for weld seaming thin metal tubes, for example cable sheaths, formed from strip by rollers and the abutting edges of which are welded, comprises a draw-off means interposed between a corrugating device for the welded tube and the welding head to prevent the corrugating torque from being transmitted to the welding point. In an embodiment a steel, copper, aluminium or stainless steel strip 2 from a reel 1 is cut to width in roller shears 3, is shaped in rollers 3a and then arranged about a cable core 5 from a reel 4. The cable then passes to a welding head 6 and the welded sheath is drawn from the head by pairs of replaceable jaws 10 carried by endless driven chains 12, rollers being guided on rails 13 to close the jaws on to the sheath to prevent rotation thereof and being opened to release the sheath by engagement with a rail 14 near the end of their travel with the sheath. The sheath is then corrugated by a device 8 having the speed of its driving motor, an A.C. commutator machine, adjusted in dependence of the longitudinal displacement of the corrugating device by a brush moving device operated by a lever in a guide rail and then wound on to a drum 9. An electrode head may be positioned a short distance in advance of the point of engagement of the edges so that the edges are fused before they meet and inert gas may be blown through the gap. The electrode may be guided to the centre of the seam by a feeler. The electrode, arc and seam may be shown enlarged on a ground glass screen provided with a scale to facilitate accurate electrode spacing and the welded seam may be worked, e.g. by hammering.

Title: Improvements in or relating to the stiffening of boot or shoe parts
IPC: A43B23/08
Filed: 1926-10-30
Abstract: 289,496. British United Shoe Machinery Co., Ltd., Lund, W. J., and Mellerio, L. P. Oct. 30, 1926. Stiffeners.-The toes and other parts of shoes are stiffened by the incorporation of fibrous material which itself is gelatinized in securing the stiffening effect. Suitable fabrics comprise fibres of cotton nitrated to a condition in which they gelatinize if wetted by a suitable volatile solvent, or fibres of cellulose acetate such as artificial silk (known under the registered trade mark " Celanese ") gelatinized by treatment with acetone and dried, is a typical instance. Fabric for the present invention may be a felted product water laid or felted by a mixture of fibres bonded by adhesive preferably soluble or penetrable by the gelatinizing agent. The fabric may be knitted or woven and in this case may comprise strands in one direction only, or mutually transverse, resistant to gelatinization. If the whole fabric is gelatinizable it is possible to drive the softened material into an absorbent adjacent layer or thin out the film of softened material. Fabrics mav be used in a plurality of superposed layers so as to produce a graded thickness of edge or a single sheet mav have its margin frayed for the same purpose. In carrying out the invention in one way, a woven cotton fabric may be nitrated and while still wet toe puff blanks are slightly treated with size soluble in the gelatinizing solvent so that while the blanks are not stiffened they will not produce fluff when packed. Toe puff blanks may be made by superposing layers of graded area of "Celanese" light weight tricot cut from scrap from the mills. The layers are increased inwards from one to three and held together by spotting with acetone. Such a 'blank is placed in the upper of a plain vamp turnshoe before pulling over and after inseaming before turning. Acetone is applied and the shoe turned and finished on a second last. A layer of material may be placed between the upper and the puff blank to prevent staining in some cases and stitch seams may be treated with vaseline to prevent passage of acetone. Specifications 143,310 and 210,168 are referred to.
