Title: Magnetic rotation of electric welding arc - automatically controlled by field adjustment through arc speed sensor
Inventor: PACHE NORBERT
IPC: B23K9/08
Filed: 1978-04-12
Abstract: Metallic workpieces, e.g. tubes, are butt welded by an electric arc which is moved along the joint to be welded by an external magnetic field. A sensor checks the rotational speed of the electric arc and compares it with a desirable value. The magnetic field is thereby adjusted until the two are equal. This compensates for an arc speed which would be too low on starting, when the workpieces are cold, and for too high a speed later when they are hot. The result is a uniform speed and a uniform welding effect.

Title: Straightening guides for rolled metal strip - has fixed and sprung guides to exert bending moment inversely proportional to radius of curvature
Inventor: KAZAKEVITSCH IGOR ILLARIONOVIT
IPC: B21B37/68
Filed: 1978-04-24
Abstract: When metal strip is being rolled it has a tendency to bend in the horizontal plane and assume a sickle shape. To avoid this defect the rolled strip (1) is passed between two pairs of fixed guides (2, 3) and a pair of spring loaded guides (5). The rates and loads of the springs acting on the guides (5) are so chosen that the sideways force is proportional to the deflection (d) of the curved strip. The positions of the guide rollers are chosen so that the bending moment exerted will be exactly sufficient to straighten the strip which has bent to the radius (R).
