Abstract: The invention relates to a method for producing multi-layer flat products (26). Said flat products preferably comprise a core (1) of solid material, laminated with a number of layers which are processed in a sequence of work steps into the final product.

Abstract: A process and a device for the continuous production of fiber-reinforced molded bodies from hydraulically setting materials, wherein the setting materials are applied in a given width from at least two dispensers with a defined thickness in at least two separate layers on conveyors moving in opposite directions. The conveyors are substrates whose color and external constitution corresponds to the outer surface of the molded body and on which the layers and surface structures of reinforcing fibers are applied. With the simultaneous injection of another material layer as an intermediate layers, the layers with the substrates are conveyed through the adjustable gap formed by a pair of cylinder rollers and the layers and substrates are united under predetermined pressure to form the molded body. Immediately after passing the gap, the molded body is deflected in a discharge direction using the cylinder rollers and is discharged with the adhering substrates.

Abstract: A strip transmission line for guiding a wave therein, including a strip-shaped inner conductor; an outer conductor surrounding the inner conductor with a clearance; a ferrite coating carried on at least one of the conductors; and at least one throughgoing slot provided in the inner and outer conductors for dividing the inner and outer conductors into at least two inner conductor sections and at least two outer conductor sections. The slots extend in a direction of wave propagation, whereby a variable current applied to the inner and outer conductors flows in one direction in one of the inner and outer conductor sections and returns in an opposite direction in another of the inner and outer conductor sections for generating a variable premagnetizing field within the strip transmission line between the inner and outer conductors to vary an electric length of the strip transmission line.

Abstract: A junction circulator suitable for high power, high-frequency use has a microwave junction zone which is penetrated by a static magnetic field. Disposed in the microwave junction zone is a ferromagnetic resonator composed of different dielectric media, at least one of which has ferromagnetic characteristics. The interfaces between the various dielectric media form three-dimensional bodies which extend over the entire height of the junction zone and which have cross sections that do not change in the direction of the static magnetic field. These interfaces may be provided by parallel ferrite rods, or a ferrite body with parallel bores.

Abstract: In a high power, high-frequency junction circulator which includes a cooled ferrite structure disposed in a microwave junction zone where it is subjected to a static magnetic field, the ferrite structure is composed of a plurality of stacked ferrite balls. A coolant flows around the balls to carry away heat.

Abstract: A junction circulator for high power, high-frequency use employs cooled ferrite material disposed in the microwave junction zone where it is exposed to a static magnetic field. The cooled ferrite material is provided by a plurality of small ferrite particles which are suspended in a liquid coolant.
