Title: Method of butt-welding and apparatus therefor
IPC: B23K9/08
Filed: 1975-03-03
Abstract: 1475450 Magnetic arc control D SCIAKY 3 March 1975 [22 July 1974] 8774/75 Heading H5H [Also in Division B3] A method of butt welding comprises striking an electric arc across a gap between edge faces of parts to be welded together, applying a magnetic field or fields so as to move the arc over the edge faces of the parts so as to describe a continuous path made up of a number of presses arranged side-by-side, and pressing the parts together. As described, the method is applied to the butt welding of thick walled pipes 1, 2, Fig. 5, i.e. pipes having a thickness exceeding inch. The pipes may be connected to a high current D.C. source to strike an arc between the ends of the pipes which are located within solenoids 3 which create a radial magnetic field to cause rotation of the arc. A hollow electrical conducting drum 9 is disposed within the pipes and is connected to a D.C. source to create a magnetic field in close proximity to the pipes and react with the magnetic field created by the solenoids to cause the rotating arc to move radially outwardly or inwardly, as indicated by the dotted line 10 in Fig. 9, depending on the direction of current flow in the drums with respect to the direction of current flow of the arc. When a low frequency alternating current is used for the arc, the arc will alternately spiral inwardly and outwardly. The arc current is initially at a low value and then increased rapidly to raise the pipe ends to the fusion temperature whereupon they are pressed together to effect the weld. A machine for carrying out the method comprises a fixed plate 12, Fig. 11, and a movable carriage 13 which are mounted via a base and each carry a clamp 14 operated by an hydraulic or pneumatic device 15 for holding sections of pipe 19 to be welded. Back bars 17, 18 on the plate and carriage resist movement of the pipe sections when the sections are pressed together during welding by movement of the carriage. Permanent or electromagnets for effecting the rotation of the arc are held in the clamps 14 and the current for the arc is supplied to the plate and carriage which are insulated from the frame. Current is supplied to the bars 17, 18 which have conductors connected to a rod carrying a cylinder within the pipe sections for effecting the radial movement of the rotating arc.

Title: Procesf or obtaining deuterium-enriched hydrogen compounds
Inventor: WETZEL KLAUS
IPC: C01B4/00
Filed: 1960-03-14
Abstract: Deuterium-enriched hydrogen compounds are obtained by distilling an azeotropic mixture of nitric acid and water under reflux to effect counter-current liquid-vapour extraction between ascending vapour and descending liquid and a D-enriched concentrate is removed overhead, while the D-depleted acid still residue is recovered as such, or as oxides of nitrogen either by separating free or free and combined H2O, reoxidised if necessary, and H2O of natural isotopic constitution is added to reconstitute an azeotropic mixture, which is recycled to the distillation. Thus, the still residue may be distilled with concentrated H2SO4 to form anhydrous HNO3, which is diluted with H2O to form the azeotrope. Alternatively, the residue is reacted with a weak base, and evaporated, and the resulting nitrate is calcined in air or O2 to form nitrous gases, which are absorbed in H2O to form the azeotrope.  The N15 isotope is also concentrated in the still residue.
