Title: Improvements in or relating to welding tubes to sheet and like material
IPC: B23K9/028
Filed: 1957-10-14
Abstract: 824,586. Welding by fusion. REVERE COPPER & BRASS Inc. Oct. 14, 1957 [Oct. 30, 1956], No. 32052/57. Class 83 (4). [Also in Groups XI and XXXV] An arc-welding gun for welding a circular joint between a tube and an apertured plate has a mandrel insertable within the tube to locate the gun during welding. The gun has a handle 7 with a trigger switch 9 secured to a casing 1 which is pressed against the plate 143. A mandrel 35 having rotatable collars 37 for engaging the interior of the tube 147 is integral with a housing 17 rotatably mounted by ball bearings 31 in the casing 1. The housing 17 is rotated by an electric motor through a flexible cable 61 a worm and a worm-wheel 45. A holder for a non-consumable electrode 43 consists of a contact tube 85 having a retaining nut 96 at one end and a split collet 95 at the other, and concentric tubes 73, 77 between which are passages for cooling water. The current supply cable is surrounded by and connected to the inlet water pipe. Shielding gas is supplied through a pipe 121 to the space between the contact tube 61 and the tube 77 and passes through the slots in the collet 95 to a gas nozzle 125. The holder is rotatably carried in an eccentric sleeve 99 in an insulating block 19 secured in the housing 17. The distance of the electrode 43 from the axis of the mandrel 35 is adjustable by rotation of the eccentric sleeve 99 which is frictionally locked in position by the head of a bolt 109. During welding the holder rotates relative to the eccentric sleeve to prevent twisting of the supply pipes and cables. Control circuit. The circuit is prepared by closing switches 175, 177, Fig. 10, whereupon a motor 349 drives a hydraulic pump 347 to raise a piston 333 connected to a moving iron core 331 of the welding transformer until the limit switch 343 disconnects the motor 349. Actuation of a relay 179 by the trigger switch 169 operates solenoid valves 203, 205 controlling the shielding gas and cooling water. After a short delay, a pneumatic timer 235, connects up the motor 253 rotating the electrode, a high-frequency oscillator 265 coupled by a transformer 318 to the welding circuit and a welding current supply switch 281. When the arc is struck, relay 307 disconnects the oscillator unless a manual switch 327 is closed to keep the oscillator in circuit. Welding proceeds until after a delay equal to more than one revolution of the electrode and determined by a timer 371 energized by the timer 235, a solenoid valve 361 opens to allow the piston 333 and the core 331 to drop so that the welding current is progressively decreased until a limit switch 183 returns the control circuit to its initial position.

Abstract: 432,399. Coking processes; coke ovens. POLLAK, J. E., 20, Holborn, London.-(Hinselmann Koksofenbauges; 30, Zweigertstrasse, Essen, Germany) Nov. 8, 1934, No. 32147. [Class 55 (i)] To improve the yield of bye-products, such as benzol, from coke ovens, the distillates, during the first portion of the heating period, are led off by a relatively long path through the oven chamber, or through the hot brickwork, or by both these paths, and, during the latter part of the heating period are removed by. a shorter path to avoid over heating. In Fig. 1, the distillates from the chamber a first pass through the free space above the charge to an opening f leading to a conduit b, the openings c being closed by bricks d. Subsequently, the distillates are withdrawn through the openings c or their way to the main g. The conduits b of adjacent ovens are arranged as close as possible so that heat exchange results between the gases flowing out from adjacent oven chambers which are arranged to operate so that the contents of adjacent ovens show the greatest possible temperature difference. In Fig. 6, separate conduits b<1>, b<2> are provided, conduit b<1> taking off the gases during the earlier part of this process when valve h is closed. In Fig. 7, openings k are formed in the heating walls, and lead by conduits to conduit b during the first period when decomposition is desired, the conduits are then closed by bricks, and the distillates are withdrawn only through the oven chamber and conduits b during the latter period.

Title: Improvements in or relating to methods of producing hexachloro-cyclohexane
IPC: C07C17/02
Filed: 1955-11-17
Abstract: Benzene hexachloride is prepared by the reaction of benzene and chlorine under the action of actinic radiation in the presence of an ammonium salt.  Suitable ammonium salts are ammonium chloride, sulphate, phosphate and nitrate.  It is preferable to carry out the reaction with moist benzene, e.g. benzene containing 5 per cent of water.  The ammonium salt may be added to the benzene in the form of an aqueous solution.  The preferred ammonium salt is ammonium chloride and it may be added to the benzene, preferably in a concentration of 0.1 to 2 per cent by weight. Alternatively ammonia in benzene may be used, in which case the ammonium chloride is formed during the chlorination.  One detailed example is given.  The process gives rise to increased yields of the gamma isomer of benzene hexachloride.
