Patent DE-2805921-A1 (DE)
Title: Heat exchanger with spiral wound wire for fixing fin - uses loose mandrel positioned axially by magnet inside tube after pressing
Inventor: GLASS MICHA
IPC: B21D53/08
Filed: 1978-02-13
Abstract: The tubes (1) which carry the heating or cooling medium are fused to the fins (2) by pressing. Prior to pressing, the tubes receive a spirally wound wire (3) made of a material which is harder than the tube. The tube and wire spiral are brought under the tool set (5, 6) of a press with the extended surface underneath. The length corresponding to the width of the tool set is filled by a mandrel (4) having a slightly smaller dia. than the tube inner dia. During pressing, the tube deforms slightly due to the loose mandrel and the hard wire spiral enters the softer fin surface which at the same time receive a trough-like indentation by the corresponding shape of the lower tool. After pressing, the tube advances by a further length, while a magnet (10) acting on the core (9) controls the position of the mandrel so that it always remains under the press tool.

Title: Utilisation of inertia energy of body mass - gives motive power in space or on earth using only electrical energy in combination with magnetic field
Inventor: ZUZIC ZDRAVKO
IPC: H02N11/00
Filed: 1978-05-23
Abstract: The circular movement of a body (M) of mass (x) on a supporting body (M2) of mass (y) (which controls the movement of the first mass) causes a movement of the body M2 in the direction of the movement of body M firing a circular drive pulse which is independent of the masses of the bodies. If a third body (M3) of mass (Xi) is linked to the circular movement and its rotation is in the opposite direction, there will be a resultant parallel action in a linear direction, giving a linear pulse. If a magnetic force is exerted on the third body to brake the movement, its energy is transferred in unaltered form to body M2. The system may be used for a rocket to avoid the use of chemical energy components.

Title: Leno-edge mechanism for shuttleless loom - controls crossing ends by relative motion of healds with crossed-slot eyes
Inventor: KLOECKER HEINZ
IPC: D03C7/06
Filed: 1979-04-26
Abstract: Device for forming a leno edge to a woven fabric, partic. in shuttleless looms, comprises two alternating heald shafts moving in opposition to each other. The front shaft carries two needles in which standard ends are drawn, the rear shaft carrying a crossing heald which has two slots inclined at 45 degrees to the horizontal in opposite directions, one above the other, in which the crossing ends are drawn. In front of the crossing heald is an ancillary heald which has slots corresponding to those in the crossing heald, but with opposite inclinations, forming between them small holes which closely define the position of the ends. The ancillary heald executes a short vertical movement w.r.t. crossing to give a rapid, positive crossing action to the crossing ends. Crossing ends are given a positive horizontal movement early in the shaft movement, producing a pre-stressing which ensures a rapid and reliable crossing action. Device is realiable even at very high loom speeds.
