Patent DE-3624535-A1 (DE)
Title: High-voltage/high-power (high-rupture capacity) protection device (hybrid protection device)
Inventor: KOENIG DIETER PROF DR ING
IPC: H01H85/042
Filed: 1986-07-19
Abstract: The invention relates to a high-voltage/high-power protection device having two separate switching chambers which are filled with two different filling media (hybrid protection device). This is a protection device which covers an entire range and is dimensioned such that the filling medium which can produce the switching off in each case comes into effect even in the case of critical overcurrents in the case of which previous protection devices tended to explode, before the protection device can explode as a result of the rising internal pressure and the prevailing temperature conditions. Developments relate to the accommodation in protection-device tubes in accordance with the DIN Standard by splitting the switching path into two separate regions which are used, on the one hand, for switching off in a current-limiting manner in the event of a short circuit and, on the other hand, for extinguishing the arc at the current zero crossing (hybrid technology).

Abstract: PCT No. PCT/EP89/00460 Sec. 371 Date Feb. 28, 1990 Sec. 102(e) Date Feb. 28, 1990 PCT Filed Apr. 26, 1989 PCT Pub. No. WO89/10219 PCT Pub. Date Nov. 2, 1989.A device is disclosed for producing expanded material using cutting rollers of special design, in which the individual annular cutting rings on the cutting rollers are provided with notches in their lateral surfaces, and when the cutting roller is viewed from above, these notches are seen to be trapezoidal in shape. The invention relates furthermore to the special configuration of the stretching system, wherein the strip-shaped non-stretched material passing through is gripped laterally by two toothed belts while at the same time the material to be stretched runs up, in its center section, on a recirculating element, such as a rounde-section belt running at an appropriate speed. This belt rises far enough out of the plane of the toothed belts that the desired transverse stretching of the material is achieved. By "expanded material" is meant a foil-like material, usually metal, in which a large number of parallel-oriented incisions are made, so that this material can then be pulled apart transversely to the direction of the incisions; as a result, the material is shortened in the longitudinal direction and the webs of material left between the incisions create a more or less three-dimensional lattice.
