Title: Improvements in and relating to the joining of sheet metal by electric welding
IPC: B23K33/00
Filed: 1928-08-03
Abstract: 295,281. British Thomson-Houston Co., Ltd., (Assignees of Vienneau, J. J.). Aug. 8, 1927, [Convention date]. Welded joints; shearing. - In a method of electrically welding metal sheets, particularly for use in forming iron cores for electrical apparatus, matched teeth cut in the ends of the sheets are placed together and are united to form a joint of substantially the same thickness as the sheets by applying current and pressure progressively along a zone common to both sheets and wide enough to include the teeth of each sheet. The teeth may be triangular, and may have their tips cut off, or may be rounded or be rounded and interlocking. In order that the sides of the sheet may match, the teeth may be cut by superposing the two sheets 1, 2 on a die 3 with their sides laterally displaced by the width of half a tooth and the cutting then effected by a complementary die 4. Welding is effected by the electrical resistance process the sheets being placed on a fixed electrode 5 and welding being performed by a roller electrode 6. Two movable electrodes may be used or the sheets may be traversed between fixed electrodes. In welding a sheet which has formed the outside sheet of a roll pack and is thus coated with scale on the outside, this may be welded by matching it with an uncoated sheet. If both sides of the sheet are scale-covered one side must be previously cleaned by grinding or sand blasting.

Title: Method of forming an integral polyolefin body
IPC: H01B13/10
Filed: 1974-05-21
Abstract: 1455734 Laminates FURUKAWA ELECTRIC CO Ltd 21 May 1974 [21 May 1973] 22703/74 Heading B5N [Also in Divisions D1-D2 and H1] An integral polyolefin body is produced by subjecting a plurality of oriented polyolefin films or fibres to a mechanical pressure of 50- 1000 kg./cm.<SP>2</SP> to form an integral body therefrom, the polyolefin in the films or fibres being such that (a) K determined from melting curves by differential scanning thermal calorimetry is less than 70%, (b) the long period L determined from small angle X-ray scattering intensity is greater than 350Š and (c) crystallinity C is greater than 70%, the values of K, L and C being determined by tests, details of which are given. The polyolefin may be polyethylene, isotactic polypropylene, polybutene-1 or poly- 4-methyl-pentene-1. Suitable polyolefin films and fibres may be produced by extrusion, the then drawn to at least twice the original dimension at temperature more than 30‹ C. below the melting point and tensile stress then applied to the material while soluble portions are extracted therefrom in a solvent having a temperature from 20‹ C. above to 10‹ C. below the temperature at which the drawn material would be dissolved when no tensile stress is applied to the drawn material. Pressing may be effected by means of metal rolls which may be embossed. Pressing may be applied at room temperature or at a temperature higher than the glass transition temperature but lower than the thermal distortion temperature. The polyolefin may be crosslinked by chemical means using organic peroxides or ionizing radiation. Polyolefin in fibre form may be mixed with cellulosic fibres and formed into paper-like sheets. Layers of the fibrous material or films may be superposed in a direction parallel, at right angles or at random with respect to each other and bonded together during pressing. The materials produced have good resistance to oil and heat, good dimensional stability and electrical insulation properties.

[Class 94 (i)] In machines for wrapping safety razor blades, and in which a scoring block descends upon an inner wrapper superposed upon an outer wrapper. before the application of a blade and subsequent closing, the scoring block is provided with grippers which hold the side flaps of the wrapper against the sides of the block during transfer to a conveyer chain : the outer wrapper 42, Fig. 5, is fed into position beneath the scoring block 91, Fig. 4, after having received gum on one of the end flaps. The inner wrapper 57 is cut from a web by a knife 83 and fed into position on the outer wrapper. The scoring block 91 descends and co-operates with a die 91a to score the wrappers on the lines x, x z, z, at the same time fingers 92, Figs. 4 and 6, close in to hold the flaps b, c against the sides of the die. The block, with the wrappers hold on it, moves to the left, and, upon the fingers opening, the wrappers are deposited on holders 150 on a conveyer chain. The vertical and horizontal movements of the die are obtained by means of a pivoted guide 125, 126 and a lever 142 and link 140. The wrappers are scored by a second block on the lines x, y, to define the flaps d, e and advance to a stage where a razor blade is deposited. The flaps b .. e are folded over by known mechanism and the packets are stacked in a magazine. According to the Provisional Specification the blades may be placed on the wrappers by electromagnetic or suction means, and a feeler may be arranged to operate electromagnetic means to prevent the feed of a wrapper in the absence of a blade and vice versa.

Title: Improvements in or relating to methods for the manufacture of metal or metal-ceramicmouldings
IPC: C22C32/00
Filed: 1962-06-14
Abstract: In a process of producing a sintered metal or metal ceramic compact, an oxide carrier and a reducing agent are added to the powder mixture which is then compacted and heated to a relatively low temperature not substantially greater than that required to initiate an exothermic reaction between the oxide carrier and the reducing agent so that sintering is effected by the heat liberated by the exothermic reaction.  The mixture contains 0.5-5% each of the oxide carrier and reducing agent which have a maximum grain size of 200 microns.  The oxide carriers may be ferrous oxide, manganese oxide, cuprous oxide, potassium chlorate, sodium nitrate, calcium sulphate, chromates, bichromates, permanganates or the oxide of the metal powder being sintered; the reducing agents may be phosphorus, carbon, sulphur or compounds thereof, zinc or tin.  The metal powder used as a maximum grain size of 500 microns and examples are given of the sintering of ferrous materials at 800-850  DEG C. and copper and copper zinc alloys at 550  DEG C.  The sintering can be carried out in an oxidizing atmosphere and charcoal and phenol resins may also be added to the powder mixture in order to produce a porous structure after sintering.

Title: Improvements in or relating to the stripping of finely divided catalyst
IPC: B01J8/00
Filed: 1954-08-06
Abstract: Finely divided hydrocarbon conversion catalyst, used for example in a cracking process, is stripped, prior to regeneration, by passage in a fluidized condition from a hydrocarbon conversion zone 7, Fig. 1, via line 5 to a separate stripping zone 1, where it is contacted with one or more high velocity jets of steam introduced at 10, immediately separated from this steam, and collected in a fluidized bed 9 through which further steam entering at 4 is passed to supplement the stripping action of the steam jets.  Valve 8 controls the flow of catalyst in line 5. Stripped catalyst is removed at 3 and stripping gas passed through line 11 to the reactor.  Baffles or partitions 6 are arranged in the lower part of the stripper.  In an alternative arrangement, <PICT:0754893/III/1> <PICT:0754893/III/2> Fig. X, the jets of steam are introduced at 10 into the transfer line 5, and this line discharges tangentially into an inner cylinder 15 open at the bottom and closed at the top; separated stripping gas passes via pipe 13 to the reactor, while the stripping gas entering at 4 leaves at 2. In modifications of the apparatus of Fig. X (a) the steam jets lead tangentially into the cylinder 15; (b) steam is injected into an uprising section of line 5 and serves as a control of the rate of flow of catalyst in place of valve 8.  In a further modification a cylinder open at both top and bottom is arranged in the stripper, and line 5 enters the stripper tangentially.
