Title: Automatic arc welding method and apparatus
IPC: B23K9/30
Filed: 1969-06-04
Abstract: 1276015 Welding by fusion NIPPON STEEL CORP 4 June 1969 [7 June 1968] 28269/69 Heading B3R [Also in Division F2] In automatic arc welding apparatus for fillet, butt or build-up welding, a welding head 19 has weaving motions imparted to it by apparatus 28 in which a single original rotation is converted into two differently directed to-and-fro motions which are then compounded to produce the desired weaving motion. In Fig. 1, a shaft 5, gear-driven by an electric motor 1, imparts variable amplitude rectilinear reciprocation to a plunger 6 via an adjustable throw crank 5-1 and a connecting rod 6-1, and variable amplitude circular oscillation to a post 18 via a two-speed gear, a shaft 15 and an adjustable throw crank 15-1 engaging a slot in a lever 16 carrying said post. A rod 6-2 fast with the welding head 19 is pivoted to the plunger 6 and is slidably carried in the post 18. The two-speed gear provides ratios of 1/2 (e.g. for 8-shape weaving) and 1/1 (e.g. for circular weaving) between the shafts 5, 15 and comprises idlers 11, 12 meshing gears 7, 8 on the shaft and selectively shifted, respectively by levers 9, 10, into mesh with a gear 13 on the shaft 15. The weaving motion is determined by the setting of the cranks 5-1, 15-1, by relative rotational pre-setting of the shafts 5, 15 (when disconnected from each other), and by the ratio of the two-speed gear. The weaving motion of the rod 6-2 may be 8-shape, U-shape, circular, elliptical or straight. In Fig. 4B (not shown) the post 18 is replaced by a second plunger which is rectilinearly reciprocated, with variable amplitude, at right angles to the plunger 6, and is pivoted to a sleeve carrying the rod 6-2. The adjustable throw cranks are as shown in Fig. 3, wherein a crank-pin 5-1 is fast with a block 4-3 which is slidable in a box 4-4 and manually adjusted by a screw 4-2. In the vertical fillet, gas-shielded, arc welding of Fig. 5, the weaving apparatus 28 is mounted on a carriage 32 which is elevated, by a motor 31, on a rail 34 attached to the workpiece 42 by permanent magnets 33. The welding head 19 is pivoted at 38 to an arm 37 fixed to the apparatus 28. The weaving rod 6-2 is connected, via an insulating joint 47, to a sleeve (57) slidable along a rod (50) fast with the head 19. The compounded motion 49 of the rod 6-2 is combined with the oscillation of the head about 38 to produce the desired weaving 41 at the fillet. The arm 37 can be changed in length to align the head with the fillet. The head 19 is fed through a conduit 45 with electrode wire 46, by a motor (71), from a reel 70, and with CO 2  gas from a bottle (60). Knobs 61, 62 respectively vary the speed of the motor 1 and control a timing device for arresting motion during welding. Switches 63, 64 are provided for the weaving and elevating motors 1, 31. The cranks within the apparatus have their throws adjusted through an opening 66.

Patent GB-283163-A (GB)
Abstract: 283,163. I. G. Farbenindustrie Akt.- Ges. Jan. 5, 1927, [Convention date]. Ethylamines; heterocyclic bases; hydrocarbons. -Organic bases are obtained by passing a mixture of acetylene and ammonia over a catalyst consisting of an inorganic salt which is capable of forming an addition compound with ammonia and is not reduced by acetylene, such as a metal chloride. The formation of acetonitrile is negligible. Preferably, the catalyst is a halide which forms an additional compound with ammonia which is stable at the reaction temperature. Suitable catalysts may be prepared by soaking a carrier such as pumice, asbestos, or coke, dried at 500-600‹ C., in a solution of an anhydrous halide in absolute alcohol or methanol, evaporating the solvent, and, if desired, treating the mass with ammonia at ordinary or raised temperature. The catalysts mentioned are obtained from zinc chloride, an equi-molecular mixture of zinc and ferric chlorides, and an equi-molecular mixture of cadmium and cupric chlorides. The reaction is effected at 280-350‹ C., but as the reaction is exothermic it is preferred to use a diluent gas which is constantly returned to the catalytic apparatus. In an example, 400 litres of ammonia per hour are circulated over a zinc chloride catalyst and 10 litres of ammonia and 10-20 litres of acetylene are added to the stream while 10 litres are withdrawn after passing the catalytic apparatus. The gas withdrawn is cooled to separate liquid products, and the uncondensed gas contains, besides ammonia, some hydrogen and heavy hydrocarbons. The liquid products comprise 15-20 per cent, chiefly diethylamine, 5-6 per cent tri-ethylamine and cyclic bases rich in hydrogen, 60-65 per cent a- and gamma-methyl-pyridine, and 10-12 per cent higher methyl pyridines and polynuclear bases. i The Specification as open to inspection under Sect. 91 (3) (a) describes the catalysts as preferably capable of forming addition compounds with pyridine, and does not limit them to those which are not reduced by acetylene. This subject-matter does not appear in the Specification as accepted.

Title: Dynamo-electric machines

Abstract: 1,137,944. Improving commutation in dynamo-electric machines. NATIONAL RESEARCH DEVELOPMENT CORP. 25 Sept., 1967 [24 June, 1966], No. 28451/66. Heading H2A. Commutation is improved in an electric motor by the use of a double or duplex winding consisting of two sets of coils T1, T3, T5 and T7, and T2, T4, T6 and T8 each connected in the usual way to alternate segments, but in addition, each being centre-tapped through resistors R to the intermediate segment and the two halves of each coil having a high mutual inductance. By means of this transformer action, commutated current in each winding-half is reflected into the other half still short-circuited by the brush B1 or B2, and because of the low stray inductance its path is almost entirely resistive through resistor R. In addition, since these windings are connected in staggered relationship to the same segments, each alternately provides a resistive discharge path for the other. However, in the preferred arrangement shown, these windings do not carry the main load-current of the machine. This is done by a conventional winding L1, L2 . . . L8, for which the two tapped windings provide a resistive discharge path. The tapped windings may be bifilar or concentric, and lie in holes below the slots or at the bottoms of the slots and covered with magnetic shims, to secure a high degree of coupling. The loss in resistors R may be reduced by connecting them in series with non-linear devices such as back-to-back silicon diodes having a threshold voltage sufficient to suppress parasitic currents (Fig. 4, not shown). The resistors R may be replaced by resistive conductors in the tapped windings. The arrangement is particularly suitable for A.C. motors.

Abstract: 1,110,060. Vehicle transporter; endless chain conveyer. R. BAJULAZ. 7 July, 1965 [21 July, 1964], No. 28829/65. Headings B8A and B8E. An endless-chain vertical transporter for vehicles has each platform 34 horizontally pivotable relative to joist 35, which joist is carried integrally by lateral member 45 pivoted at 47 to support 46 carried by endless chains 33. Each support 46 carries a roller 55 and rollers 52 which move in the vertical channels shown to guide and stabilize the platform. A platform 34 therefore moves vertically as the chains 33 rotate, its member 45 for stability resting laterally on support 46. Each lateral member 45 carries roller 67 which engages with cam 65 at the top of the upward movement to cause a leftward pivoting movement of member 45 about pivot 47. This causes gears 62 to move over teeth 68 and by the operation of cams to cause platform 34 to pivot horizontally about vertical axes to a retracted position so that it now occupies less space (as shown) for the downward journey on the left-hand side of chains 33. When the platform reaches the bottom of the chains 33 the reverse process takes place and the platform 34 is extended and pivoted out into its fully operative position as shown for the upward vertical movement. Garage (Figs. 1 and 2).-Two such transporters are utilized facing each other so that two platforms 34 may each elevate or lower a car between them. At each floor 18 an element 19 is provided pivoted at 20 and operated by a fluid cylinder 23 to provide a gap in the floor to permit the rise of the platforms. Platform 34, Fig. 10 (not shown).-Each platform comprises elements 34 pivoted at 36 to joist 35 and operated by a beam 41 coupled by pins 40 to each element 34 so that camoperated movement of beam 41 swings all the elements 34 simultaneously in the horizontal plane from the retracted into the operating position shown.
