Patent DE-3328839-A1 (DE)
Title: Process for the production of a layered structure for vertical magnetic data storage
Inventor: BRUNSCH ARWED DIPL PHYS DR
IPC: G11B5/84
Filed: 1983-08-10
Abstract: In the case of a process for the production of a layered structure for vertical magnetic data storage, first of all a soft-magnetic layer (2) and then a carrier layer (3) of non-magnetic material are applied to a substrate (1). A multiplicity of discrete core tracks are made in the carrier layer (3) by bombardment with high-energy heavy ions. The core tracks are converted by etching into corresponding channels. Finally, the channels are filled with magnetic material, so that a microneedle structure comprising a multiplicity of needles (4) of magnetic material, arranged perpendicularly to the substrate surface, is produced, i.e. a magnetic form anisotropy perpendicular to the plane of the layers results. <IMAGE>

Title: Device for damping oscillations in fluids
Inventor: KOTAUCZEK FRITZ
IPC: F16L55/05
Filed: 1983-10-22
Abstract: A device for damping oscillations in fluids has a housing which is provided with a pressure medium supply opening and pressure medium outlet openings, in which housing a guided piston separates a pressure medium supply space from a pressure medium space. The pressure medium supply space corresponds to the pressure medium space through restrictor holes which are arranged in the piston base. A piston rod which is arranged on the piston on the pressure medium space side guides a spring which influences the movement of the piston. In order to achieve a device which is optimised in terms of material and structural volume and comprises a small number of components which can be produced at a low cost in terms of production engineering, the pressure medium space is partially formed by an annular space which is located between the piston rod and the piston shaft of the piston which is constructed as a hollow piston.

Patent DE-3401060-A1 (DE)
Inventor: STOEHR WILFRIED
IPC: G06F3/14
Filed: 1984-01-13
Abstract: A process for graphically representing a simulated workpiece as processed by a numerically-controlled machine tool. Stored data defining the workpiece and the tool as well as program data defining relative movement therebetween are used to generate polygons which represent the workpiece and the tool and the path of movement of the tool. These polygons are hierarchically ordered and liked. Corresponding to the hierarchic order of the polygons, intersection point calculations in the linkage are made only for the workpiece polygons which overlap the tool polygon. The image of the processed workpiece is generated successively through the continuous superposition of the changing workpiece polygons with the processing polygons corresponding to the tool and its path. Workpiece edges which drop out are erased, and invisible workpiece edges are nto represented.

Title: Circuit arrangement for line feeding ancillary devices of a telephone set
Inventor: MOSES KLAUS M
IPC: H04M19/08
Filed: 1984-02-08
Abstract: For line feeding ancillary devices of a telephone set, a shunt component which limits the line voltage upstream of the current stabiliser being connected between the speech wires and a current stabiliser which limits the feed current of the talk-listen circuit, said shunt component being connected to the feed terminals of the ancillary devices, the shunt component is formed by a reactance stage with a constant resistance characteristic. In this way, stabilisation of the operating voltage of the loudspeaker amplifier is achieved which adapts automatically to the loop current. This provides a loudspeaker amplifier with maximum AF power. If a further ancillary device, for example, the control device of the telephone set, is connected to the shunt component along with a loudspeaker amplifier, the control device is supplied with the aid of a current distribution circuit with constant current and the loudspeaker amplifier is supplied with the surplus current.

Title: Process for severing web-shaped material to form yarns
Inventor: ARNOLD ROLF
IPC: D01D5/42
Filed: 1984-10-22
Abstract: The invention relates to a severing process which is also suitable for inhomogenous severing material. The object is to guarantee the clean production of yarns from sheet-like structures which it has hitherto been impossible to use for this. In the solution according to the invention, parallel cutting elements fastened on a cutter bar vibrate in the cutting direction, the draw-off speed v of the material web, the frequency f of the cutter bar and the amplitude a of the cutting elements being coordinated with one another according to the relation  a . f > v/2. According to this relation, an interruption of contact between the severing material and the severing tools occurs during each period of oscillation. The severing resistance is thereby reduced and an exact production of yarns from inhomogenous material containing, for example, island-like thickenings, becomes possible. Moreover, the lifetime of the cutting tools is increased.

Title: Apparatuses for transferring bodies of geometrically defined shape from a current of liquid into an adjoining current of liquid, of different form, with simultaneous separation of the two liquid circuits
Inventor: BOLZ ALFRED
IPC: B65G51/02
Filed: 1985-03-11
Abstract: The present invention relates to an apparatus by means of which bodies of geometrically defined shape, which are being hydraulically transported in a first conveying channel by means of a first current of liquid and are passed into a second conveying channel, in which these bodies are taken over by a second current of liquid and, in this manner, further transported through a second conveying channel, without any mixing taking place between the two currents of liquid whose composition may be different, depending on the application required. In this arrangement, the separation of the two currents of liquid takes place in a pressure-tight liquid container which creates a pressure compensation between the end of the first conveying channel and the start of the second conveying channel. A control, dependent on the level of liquid, ensures that the pressure of the compressed air cushion is always so high that the liquid in the second current of liquid cannot pass into the liquid container.
