Title: Electric arc welding
IPC: B23K/
Filed: 1959-03-24
Abstract: 901,333. Welding by fusion. AIR REDUCTION CO. Inc. March 24, 1959 [April 2, 1958], No. 10214/59. Class 83 (4). [Also in Group XXXV] In arc welding using a continuously fed wire electrode, the current source has a voltage below that required to sustain an arc so that the electrode repeatedly and rapidly contacts the weld pool, and the supply circuit has substantial inductive reactance to limit the shortcircuit current and to extend the duration of the arc. The short circuits are at a frequency of 40 . . . 250 per second and metal is removed from the electrode only when a short circuit occurs. The voltage is 1 . . . 10 volts below that required to sustain an arc. The supply source is D.C. of either polarity, has a constant or rising volt-ampere characteristic and is a motor-driven generator, a transformer-rectifier set or a battery. The welding circuit has an inductive reactance of 40 ... 1,000 microhenries of which part may be inherent in the circuit and part added. The current time graph of Fig. 7 relates to a process in which the arc is sustained until short-circuit occurs. That shown in Fig. 9 relates to a process in which the arc breaks down before short-circuit occurs. The process is particularly applicable to the welding of mild steel using a shield of carbon dioxide. Other shielding gases referred to are nitrogen helium and argon + 1% oxygen.

Patent GB-556829-A (GB)
Title: Improvements in or relating to esters of dipentaerythritol and to methods of producing same
Filed: 1941-08-12
Abstract: 556,829. Paints. STEVENS, A. H. (American Cyanamid Co.). Aug. 12, 1941, No. 10255. [Class 95] [Also in Groups IV and V] Dipentaerythritol esters are produced by heating dipentaerythritol with a mixture of unsaturated fatty acids obtained from a natural drying or semi-drying oil as the sole acidic esterifying agent. When the esterification is not complete the incompletely esterified products may be separated from the completely esterified portion by extracting with a lower aliphatic alcohol. As sources of the fatty acid mixtures many oils are listed. The completely esterified products have good drying properties and the product with three esterified groups is compatible with many resinous and plastic materials such as urea formaldehyde and melamine formaldehyde resins, ethyl cellulose and rubber derivatives both in solutions and in films. For example, it is compatible with polystyrene in xylene, cellulose acetate butyrate in methyl ethyl ketone, cellulose nitrate in toluene methyl ahydroxy butyrate mixture, and with chlorinated rubber in xylene. The dipentaerythritol esters are suitable for varnish making by heating with ester gum, phenol formaldehyde resins, or natural resins such as copal and dammar. Thus a source of abietic acid such as gum rosin may be heated with dipentaerythritol to form a neutral ester, which is then heated with a dipentaerythritol ester of soya or linseed oil acids. In examples (1) dipentaerythritol is heated with soya acid, and the product shaken with ethyl alcohol to remove unreacted acids and mono esters; the product is made into a paint with white lead titanium oxide, zinc oxide, talc and oil; (2) and (3) esters of linseed oil, dehydrated castor oil, tung oil, and castor oil acids are prepared similarly, the properties of the products being tabulated; (4) dipentaerythritol is esterified with half the theoretical quantity of soya acids and the product is added to melamine formaldehyde resin in butanol, xylene being added, and to a butylated urea formaldehyde resin in butanol and xylene.

Patent GB-592583-A (GB)
Title: Improvements relating to the moulding of plasticised synthetic rubber-like materials
IPC: H01B13/14
Filed: 1944-05-26
Abstract: <PICT:0592583/IV/1> Plasticised synthetic rubber-like materials such as plasticised polyvinyl chloride, which are normally liable to shrink and crack when moulded and amalgamated by heat in strips round an elongated body, are subjected to a heat treatment while suspended substantially vertically under a relatively slight tension in order to cause them to undergo a shrinkage which will enable moulding to be effected without cracking.  The heating may be effected in a convection oven, a liquid bath or by irradiation. In an example, plasticised polyvinyl chloride strip 5 passes through a glass-walled chamber 1 heated by infra-red lamps 6, the chamber being kept as air-tight as possible.  Depending loop 5a is associated with detector means 14 and 15 which automatically vary the speed of rollers 12 when the loop rises above or descends below predetermined limits.

Patent GB-547865-A (GB)
Title: Improvements in electric liquid heating devices
IPC: A47J27/21
Filed: 1941-08-15
Abstract: 547,865. Electrically heating liquids. HADDAN, R. (Moffats, Ltd.). Aug. 15, 1941, No. 10409. [Class 39 (iii)] [Also in Group XXXVII] A kettle 1 provided with trunnions 2 journalled in slots 3 is heated by an immersion heater 10 having a grid-like portion 10a and leads 10b extending through the kettle wall to contacts 11 carried by an insulating block 13. The block is secured by a screw 14 to a bracket 15 carried by the kettle and having a finger 16 to engage the end of a spring 37. The supporting arms 4 are carried by a casing 19 bolted to a splash plate 21 of a stove, and an insulating block 23 with terminals 22 is mounted on a bracket 36 carried by the splash plate. Connectors 25 carried by an insulating block 26 are interposed between the contacts 11 and terminals 22. The blocks 23, 26 are pressed upwards by springs 28, 27 respectively, the upward movement being limited by stops. The parts which are in electrical contact are silver-capped. Normally the blocks 23, 26 are pressed upwards by their springs and the members 22, 25 are not in contact if the kettle is tilted or removed. To prevent the block 26 from being depresssed, except by engagement of the contacts 11 with the connectors 25, a spring arm 37 with projection 38 engages the underside of the block 26. When the kettle is rocked to bring the contacts 11 into engagement with connectors 25, the end of the finger 16 engages a projection at the top of the arm 37 and releases the arm from the engagement with the block 26. Continued movement of the kettle causes contact of the parts 11, 25. The kettle is locked in its operative position by engagement of the hooked end of the finger 16 with a slot in the projection 38. The connectors 25 and terminals 22 are automatically disconnected if the element 10 is overheated. When in the heating position, anticlockwise movement of the kettle is prevented by engagement of a toothed wheel 44, carried by a spindle 45 embedded in fusible metal in a tube 46, with the end of an arm 40. Melting of the metal allows the spring 42 to rotate the kettle by allowing the wheel 44 to rotate free of the arm 40, and this disengages the projection 38 from the block 26 so that the contacts are disengaged. When the metal solidifies, the device may be manually re-set. When the liquid in the kettle boils, steam from a vent 44 impinges on a bulb 52 to generate vapour pressure therein, which actuates a diaphragm 48 and switch 49.

Abstract: 834,164. Sound film or tape apparatus. CAILLIOT, S. L. L. April 2, 1958 [April 2, 1957], No. 10635/58. Class 40 (2). In a record support in the form of a thin helical band sufficiently flexible that the coils subside on each other such that the overall thickness is the sum of the thicknesses of the coils, the end coils are joined to form an endless band, notches being provided along the whole length of the inner or outer edge for the purpose of rotatively driving the superposed coils. Fig. 1 shows an embodiment in which the end turns are joined outside the coil, and notches are provided at the inner end of the band, while Fig. 4 shows an inverse arrangement. Fig. 9 shows an exploded view of a cassette housing a coil of the kind shown in Fig. 1. The coil in its collapsed form encircles a splined driving member 58 on a shaft 57 which when rotated causes the band to be passed from the bottom of the coil on to the top, the top turn passing over a plate 49 and under a window 47 through which a transducer operates. An alternative arrangement, working on similar principles, for a band with outside notches is described with reference to Figs. 12 and 13 (not shown). The cassette carries straight flanges 56 by which means it may be supported in slides 73 in a reproducing apparatus H, Fig. 14. Drive is effected from a motor 75 via jockey wheels 76 and a flywheel 77. A magnetic transducer 79 mounted on an arm 82 may be moved across the band step by step at each completion of movement of the full length of the tape by an electrically operated ratchet device, Fig. 16, tripped by a shorting strip 109 on the band. In the case of a spiral track on the band the transducer arm 82 may be fed in by a lead screw. Arrangements for stepping the transducer arm backward or forward manually comprise push buttons 87 and 88, respectively, and an exact desired position on the track may be obtained by forward or backward driving of the shaft 57. The invention is not confined to magnetic recording. A vibratory stylus may be used or the band may be a translucent film through which rays from a light source 99, Fig. 15, pass and are reflected by a prism 100 on to a photocell 101.
