Patent GB-396337-A (GB)
Title: Hemstitch and embroidery seams
IPC: D05B93/00
Filed: 1933-03-29
Abstract: 396,337. Hem-stitching. FAIRWEATHER, W. C., 65, Chancery Lane, London.-(Singer Manufacturing Co. ; Elizabeth, New Jersey, U.S.A.) March 29, 1933, No. 9415. [Class 112.] In forming hem-stitch and picot-edge seams, the stitching thread ties back and holds the body material by the concatenated loops of a single thread chain stitch. The invention is illustrated by seams made by a two-needle hem-stitching machine. In Figs. 1 and 2 a stitch 4 embraces the cross-bar 3 formed by piercing the holes 2 in the material 1, and lies in the general direction of the seam line. A lateral stitch 5 out of the seam line is anchored in the material as is the complimentary return stitch 6. The stitches are formed by passing a loop of thread 7 through the aperture 2, detaining and spreading the loop below the material, advancing the material and passing another thread loop 8 through the next aperture and through the loop 7. While the material remains stationary, a thread loop 9 is passed through adjacent to the hole 2 containing the loop 8, this loop reclosing the loop 9. The single-thread chain-stitch seam above described may be combined with a twothread chain-stitch seam with the resulting ornamental effect shown in Fig. 4. A picot edge seam is produced by severing the crossbars 3 of Fig. 1.

Title: Alloys and methods of making same
IPC: C22C29/14
Filed: 1931-03-30
Abstract: An alloy for tools &c., is composed of a preponderant proportion of a boride of a refractory metal such as tantalum, niobium or vanadium and an auxiliary metal of the iron group.  In making the alloy boron and the refractory metal in just sufficient or in slight excess of quantity required to combine with the boron after a thorough mixing in a ball mill are placed in a tantalum crucible surrounded by tantalum powder inside a graphite crucible and heated in an evacuated electric furnace.  The boride is ground and after degasefication by heating in vacuo in an electric furnace is thoroughly mixed with a hydrogen reduced auxiliary metal, shaped under great pressure and finally heated in vacuo. All traces of embrittling gases are removed from the alloy by heating each of the components to a degasefication temperature in 2  vacuo before or after mixing with the other components.  The Specification as open to inspection under Sect. 91 (3) (a) includes also tungsten and molybdenum borides as examples of refractory metal borides.  This subject-matter does not appear in the Specification as accepted.ALSO:An alloy for tools &c. is composed of a preponderant proportion of a boride of a refractory metal such as tantalum, niobium or vanadium and an auxiliary metal of the iron group.

Title: Improved soldering method for soldering fins to heat exchanger tubes
IPC: B23K1/00
Filed: 1958-03-25
Abstract: 881,309. Making heat-exchanger tubes; soldering. ESCHER WYSS A.G. March 25, 1958 [April 18, 1957], No. 9557/58. Classes 83 (2) and 83 (4). In soldering fins to the external surface of a heat-exchanger tube the tube, fins and interposed solder material are introduced into a protecting tube closed at one end and heat is applied to the heat-exchanger tube while it is within the protecting tube with the other end of the protecting tube freely open to the atmosphere, the radial clearance between the fins and the protecting tube being so small that the amount of oxygen in the air in the small space is insufficient to produce sealing detrimental to the soldering. In soldering fins formed by a helically wound corrugated strip 1 on a heat-exchanger tube 2 with solder material between the strip and tube, the assembly is placed in a close fitting tube 3, e.g. of quartz closed at one end by a plug 4. The tube 3 is mounted on rollers 5 to pass it through a high-frequency induction coil 6. The assembly may be heated by resistance.

Title: Improvements in or relating to the electrical resistance welding of tubes
IPC: B23K11/06
Filed: 1940-06-01
Abstract: 540,124. Welding. SCIAKY, D. June 1, 1940, No. 9618. Convention date, June 27, 1939. [Class 83 (iv)] In the electric lap or scarf welding of tubes, particularly thin tubes of iron, austenitic chromium, nickel or other alloy steel, nickel alloys or light alloys, the blank is engaged over a conductive mandrel and held along two of its generating lines, the edges are longitudinally stretched and current is passed between the generating lines and the edges of the tube. Excessive heating and consequent deformation of the blank in the section adjacent the weld is thus avoided and subsequent treatment of the tube thus rendered unnecessary. The tube 4 with overlapped edges is placed on an electrically conductive mandrel 5, which may be water cooled, and secured by clamps 6, 12 in a V-grooved electrode support 1 so that it is in contact with the support along the lines 181 and 182. The clamp 12 engages the lapped edges of the blank only whereas the clamp 6 engages the blank and also the mandrel and is adjusted by a screw 10 so as to stretch the edges of the tube. The blank is further pressed against the mandrel by spring- pressed bolts 141, 142. The support is grooved at 3 so that it may be traversed over an electrode roller 17, which co-operates with an adjustable electrode roller 16 to effect the weld. The current, which may be intermittent, passes from the roller 16 through the lapped edges and thence through the mandrel to the support at 18<SP>1</SP>, 18<SP>2</SP> and so to the electrode roller 17. The electrode support 1 may be traversed between the roller electrodes by rotating the electrodes or by traversing the support by a toothed rack. The support may be provided with a semi-circular groove with which the blank engages along two opposite generating lines. The tubes may be oval, rectangular, &c.

Title: Separation of metals
IPC: B01J47/10
Filed: 1975-02-24
Abstract: 1499797 Metal separation NATIONAL RESEARCH DEVELOPMENT CORP 24 Feb 1975 [4 March 1974] 9632/74 Heading C1A Metallic elements are separated (at least partially) by a method which comprises passing a solid anion exchange material which carries chlorocomplexes of the metals, in a fluidized condition through a contactor in which the anion exchange material is treated with a counter-current flow of a solution containing a "complexing chloride" (i.e. hydrogen chloride, an alkali metal chloride or an alkaline earth metal chloride), so that the solution is enriched in one or more of the metals by selective depletion of the metals carried on the ion exchange material. Preferably the contactor used is one claimed in Specification 1,070,251. It is possible to effect a partial separation of the metals during the preliminary loading of the ion exchange material, by passing it in a fluidized condition through a contactor in a flow countercurrent to that of a solution of metal chlorides and a "complexing chloride". The method is readily applicable to some degree for the separation one from another of the transition metals, e.g. Zn, Ag, Au, Pd, Pt, and, in particular, Cu, Ni, Co, Mn, and Fe.
