Title: Controlling weld pool shape by a travelling magnetic field - to nullify influence of gravity and increase welding speeds
Inventor: KANO MOTOMI
IPC: H01F5/00
Filed: 1977-05-13
Abstract: A travelling magnetic field is used near the molten metal pool in a welding process, so that an eddy current is induced in the pool, and the shape of the pool is controlled by the electromagnetic driving force during welding. V)rtical welding is pref. carried out while the travelling magnetic field moves upwards near the pool, whereas in overhead welding the field travels near the pool in the welding direction. For horizontal welding on a vertical workpiece, the field pref. travels upwards at 90 degrees to the welding direction, an for horizontal fillet welding an inclined upward travel of the field is used. Pref. appts. uses the principle of a linear induction motor to produce an electro-magnetic force corresp. with Fleming's left hand rule. Process is used in welding all metals, e.g. iron, steel, alloy- or stainless-steels, Cu, Al, or Ni. The detrimental influence of gravity is nullified, e.g. in upwards vertical- or overhead-welding, so higher speeds and better quality is obtd. than in conventional welding processes.

Title: Automatic splicer for broken ends on winding frame - transfers threads from above and below into pneumatic chamber
Inventor: ROHNER JOACHIM
IPC: B65H69/06
Filed: 1978-04-13
Abstract: A mechanism including a chamber having a lengthways running groove, which can be covered by a hinged cover, and into which two ends of yarn can be introduced and spliced by means of a lateral jet or compressed air, serves to join a thread from above to a thread from below. The introduction of the broken ends of the thread into the longitudinal groove is effected by a mobile device for drawing the thread which is displaced from a position in which it locates and picks up the thread to one in which it releases it. The threads are introduced into the chamber either, not crossed, and pref. parallel to each other, and are held until the compressed air is delivered, or they may be crossed during the pivoting action of the thread drawing device. The chamber is closed by a cover. The ends of the thread from above and of the thread from below are automatically sheared. Compressed air is blown into the chamber. Used to effect a joint by a splice between an upper and a lower end of yarn, as in a winding frame, whilst eliminating all the influences which depreciate the quality of the joint and depend upon manual skill.

Title: Soft phase keying of carrier oscillation - involves generating two components, with frequency of one component increased, whilst other is decreased
Inventor: KIRSCHNER KLAUS DIPL ING
IPC: H04L27/20
Filed: 1978-07-05
Abstract: The carrier oscillation consists of linear superposition of two component oscillations, which before keying are identical in every respect. At the instant when the oscillations reach their peaks, the frequency of one oscillation is increased, and that of the other is decreased by the same amount, delta f/2, which is an integral part of the carrier frequency. After a time interval T=1/delta f the frequencies of the two oscillations are returned to their initial values. In both cases the phases of both oscillations are kept unchanged.

Title: Stranding machine spool carrier unit - has spools angularly displaced from spool positions of adjacent carriers
Inventor: BERGES DIETRICH
IPC: D07B3/06
Filed: 1978-07-19
Abstract: The axes of the spools on one carrier are positioned midway between the axes of the spools on the other carrier. The top-plates of each carrier unit cut-away sections opposite the spool axes of the adjacent carrier, which permit the axles of that carrier to be withdrawn and the spools to be removed directly from the carrier. By this means the standing machine can be reduced considerably in length since it is not necessary to leave sufficient space between spool carriers to withdraw the spool axles.
