Title: Method for fast storage elements and logical switching elements in the frequency domain on the basis of parametric frequency division and device to verify and carry out the method
Inventor: JAEGER ROBERT DR ING
IPC: H03B19/05
Filed: 1985-07-22
Abstract: In Patent Application P 3417213.0 it was described how storage elements can be constructed with non-linear reactance characteristics in the frequency domain. Two examples were indicated for this purpose, based on hysteresis phenomena (bistable areas) of the complex reflection factor. In the method applied for here, a further example of a simple storage element in the frequency domain is described which is characterised above all by a high theoretical switching speed; a speed which is otherwise achieved only with Josephson components. However, unlike Josephson components, which operate only at temperatures around absolute zero, at room temperature. The method is based on the creation of multiply stable frequency domains through parametric frequency division on a non-linear reactance characteristic which is also the subject of this application. With appropriate selection of the operating point, logical elements to combine information in the frequency domain can in principle also be constructed with the described method.

Title: Method of reducing the grinding time during the grinding of saw teeth on saw blades
Inventor: HAHN WOLFGANG
IPC: B23D63/14
Filed: 1985-10-19
Abstract: During the grinding of a saw tooth, the tooth is ground in a variable section at a high operating speed and in the remaining section at a low operating speed. This enables the idle stroke of the grinding wheel to be reduced. In addition, a more favourable distribution of the time for grinding the tooth back and the tooth face is achieved - in particular in the grinding process with continuous rotary movement of the saw blade.
Patent DE-3540021-A1 (DE)
Title: Multi-element shaped-charge lining
Inventor: SCHROEDL GEORG
IPC: F42B1/032
Filed: 1985-11-12
Abstract: A method for joining at least two parts (consisting of different materials) of the lining of a main charge (which is designed as a shaped charge) of a projectile or warhead, the parts of the lining being arranged before being joined at a distance from one another within the projectile or warhead, a part of the lining being moved by the detonation pressure of an additional charge in a straight line, at high speed, in the direction of the other part or parts of the lining, and the joining process being effected by the detonation pressure and by conversion of the kinetic energy when the parts collide. The joining process is not carried out until directly before, or during the impact of the projectile or warhead with the target object and the detonation pressure of the additional charge acts indirectly on a part of the lining, via a largely gas-tight, displaceable intermediate element, a part of the lining also remaining in an unchanged position relative to the projectile or warhead during the joining process, the additional charge being detonated before the main charge, and the main charge being detonated by the distance between the parts of the lining falling below a defined level.

Title: Process for producing magnetic heads
Inventor: ECKSTEIN KARL-HEINZ
IPC: G11B5/127
Filed: 1985-11-29
Abstract: In the case of a process for producing magnetic heads with core halves of ferrite, with a soft-magnetic alloy of high permeability sputtered or vapour-deposited onto the ferrite, and with a useful gap surrounded by the soft-magnetic alloy of high permeability, it is proposed to grind into the ferrite block serving as the starting material grooves of which the width corresponds approximately to the gap length of the magnetic head and of which the depth is chosen such that it is adapted to the later gap height. These grooves are vapour-deposited or sputtered with the soft-magnetic alloy of high permeability in such a way that they are completely filled. With such a procedure, a detachment of the sputtered-on layer from the core support of ferrite is avoided.

Title: Folding, sealing and transporting apparatus in a machine for the packaging of slabs
Inventor: KNECHT ALFRED
IPC: B65B11/40
Filed: 1986-04-16
Abstract: The apparatus (1) comprises a wheel (4) which is rotatable in steps on a shaft (10). Pockets (5) are mounted rotatably on the wheel (4). The pockets (5) have a first wall (20) and a second resilient wall (21). In a feed station (6), a slab (2), together with a portion of wrapping material (3), is pushed into the pocket (5). During the displacement of the pocket (5) into a sealing station (7), projecting tabs (15, 16) of the portion (3) are laid flat onto a sealing stay (23) connected to the first wall (20). In the sealing station (7), a sealing seam is formed by a sealing jaw (44). During displacement into an unloading station (9), the pocket (5) is rotated through 180 DEG . This design ensures that the tabs (15, 16) can be relatively wide and nevertheless do not crumple, thus guaranteeing a tight sealing seam. As a result of the rotation through 180 DEG , the slab assumes a favourable position for subsequent folding operations. <IMAGE>

Title: Process and apparatus for coating wearing surfaces and wearing surfaces produced by the process
Inventor: RETTER BERND
IPC: C23C4/11
Filed: 1986-11-07
Abstract: The invention relates to a process for coating the wearing surfaces of conveying screws by thermally spraying on a ceramic wearing layer and to a conveying screw coated by this process and also to an apparatus for carrying out this process. Worn surfaces of conveying screws are usually repaired by build-up welding. Furthermore, it is known to repair wearing parts in the ceramic industry by thermally spraying on a ceramic material. In this case, the thickness of the layer is limited, however, to a maximum of 0.5 mm. For conveying screws, in particular for extruding raw material for bricks, this limited layer thickness does not provide an adequate service life. According to the invention, therefore, before spraying on the wearing layer a backing fabric is placed on the surface to be coated before the wearing layer is sprayed on to embed and cover the backing fabric completely. The conveying screw repaired in this way is distinguished by the fact that there is embedded in the wearing layer at least one ply of a backing fabric, which allows a considerable increase in the layer thickness of the wearing layer. Finally, an apparatus for carrying out the process is distinguished in that the spraying device is on a support which can be adjusted in height by a drive and said spraying device can be moved back and forth transversely to the adjusting direction of the said support, that the mounting ...
