Title: Arc welding jig fitted with two or more electrodes - to prevent distortion when welding the periphery of thin walled tubes
Inventor: GUETTLER ROMAN DIPL ING
IPC: B23K9/028
Filed: 1975-07-25
Abstract: Jig for the arc welding of circular or spiral tube seams uses several welding electrodes. The electrodes are uniformly distributed round the periphery of the tube. In the pref. jig, two electrodes are located at 180 degrees w.r.t. each other and are each connected to a source of welding current. There is uniform heat input so distortion is avoided when welding seams on thin walled tubes. In conventional welding processes, the non-uniform heat distribution round the periphery of a tube can result in distortion so it is usual to reduce the welding current and speed. This means that the rate of prodn. is decreased and structural alterations can occur in the vicinity of the seam. The invention overcomes such problems.

Title: Charging arc furnaces through electrode - housing ring seals pass extensions and pipe cleaning tools without gases escaping
Inventor: BESKIN MICHAIL DAVYDOVITSCH
IPC: H05B7/085
Filed: 1975-09-11
Abstract: Arrangements for charging raw materials into an electric arc furnace through the centre tube of the electrode, include a housing with a lateral pipe connection for loading and venting gases, as well as coaxial openings, one of which in the bottom of the housing, allows it to be mounted on the centre tube whilst the other, at the housing top can be sealed to prevent any escape of gas, by a flap. This can be moved from a position in which its seal prevents the escape of gas during charging, to another allowing a tube section with a removable blanking piece to be threaded through the opening for piecing up the centre tube. The arrangement provides a lock making it possible to have free access to the furnace space below the electrode without detriment to the hermetic sealing, and to piece up the inner tube of the electrode in a simple and more efficient manner, without the toxic gases being allowed to escape.
