Patent DE-3918208-A1 (DE)
Title: High-voltage winding for a high-tension transformer
Inventor: RAVOT JEAN-FRANCOIS
IPC: H01F27/28
Filed: 1989-06-03
Abstract: In order to avoid additional solder joints in the case of interleaved double-disc coils having parallel conductors, the high-voltage winding of a high-tension transformer is constructed from two or more mutually interleaved winding elements (1', 2', ..., 40'; -3'', -2'', ..., 36''), the winding start (E) of one winding element (1'', 2'', ...) starting such that it is offset within the other winding element (1', 2', ...) by more than two turn layers, and the winding end of the other winding element (1', 2', ..., 36') accordingly ending within the one winding element (1'', 2'', ..., 36'') such that it is offset in the direction of the winding start by the number of turn layers corresponding to the offset at the winding start. The magnitude of the offset in this case also determines the magnitude of the series equivalent capacitance of the complete winding and thus the capability to withstand sudden surge voltages. <IMAGE>

Title: Window frame mfg line - additional frame tipping operations are avoided by moving the frame to a weld dressing machine in a near vertical on end position
Inventor: STUERTZ KARL-HEINZ
IPC: B23K37/04
Filed: 1989-06-22
Abstract: A process for mfg. frames from plastic or metal profiles involves welding the frames at the corners and dressing the welded corners one after the other in a machine which rotates the corners into a suitable position for dressing.  In the described process additional frame tipping steps are avoided by the frame being welded together in the vertical position and then moved to the dressing machine in the on end position. The frame with one corner at the bottom is dressed and then rotated several times to allow the operation to be performed on each corner. USE/ADVANTAGE - For welding and dressing the corners of frames, particularly window frames, produced from extruded profiles. Additional frame tipping steps used in previous equipment are eliminated.

Title: Matrix printer circuit for operation of mechanical printing elements
Inventor: KRINGE HORST
IPC: B41J2/30
Filed: 1989-07-10
Abstract: The matrix printer circuit is used to control the mechanical printing elements incorporated in the printing head which is  displaced along the printing line, with the control for each  printing element providing a printing signal when the printing  element has reached a given position in the path of movement to the printing position. Each printing element has an associated delay element for mechanical activation of the printing element in response to the printing signal after a defined delay. Pref. the delay device is provided by a counter which is set to a given value dependent on the printing head velocity by the printing signal, with activation of the printing element upon reaching a final count value.
Patent DE-3923545-A1 (DE)
Inventor: EISERMANN GUENTER
IPC: G01R31/00
Filed: 1989-07-15
Abstract: The said loads receive their operating instructions from an electronic control unit (ECU). For test purposes, this unit is connected, in accordance with the criteria of DIN/ISO 9141, to a diagnostic computer (PC) in which the test software is stored on a corresponding carrier, for example a diskette. During a test, a shunt is inserted into the current path between direct current source (2) and load (15), which, after activation of the load to be tested by the diagnostic computer (16), generates a voltage drop dependent on the current consumption of the said load. This voltage drop is measured and compared with a load-specific nominal value in the diagnostic unit. In the case of a difference, the magnitude of this difference produces an accurate indication of the actual damage in the load or error in its function.

Inventor: SONNEWALD UWE DR
IPC: A23L19/12
Filed: 1990-04-20
Abstract: Plasmids are described, the DNA sequences of which when inserted into the genome of a plant modify the carbohydrate or protein concentration and the carbohydrate or protein composition, as well as plant cells and plants that contain those plasmids. DNA located in plasmids described reduces in the plant the ADP-glucose-pyrophosphorylase activity and thereby the starch concentration and at the same time increases the mono- and oligosaccharide concentration. Other DNA in plasmids reduces or increases the protein concentration. Plants that contain those plasmids are suitable inter alia for the extraction of sugar or as protein-enriched food or fodder.

Title: Prodn. of packing material -  involves crumpling sheet of flexible material in controlled pattern
Inventor: LESCH HANS
IPC: B65D75/34
Filed: 1990-08-31
Abstract: A thin sheet of material is crumpled in a regular manner to form a packing material. The sheet (18) of material is placed between two belts (10,11) which are made from an elastic mesh.  These belts are stretched and then pressed against the material (18) with the aid of guide rollers (12). Depressions are formed on both sides of the material and the belt tension is then released.  The friction between the belts and the material causes the material to contract and crumple as the elastic belts contract to their free dimensions. USE/ADVANTAGE - Low cost method of producing packing material.

Title: Deep drawing limit ration increase process - with constant holding-down force dependent upon fold formation
Inventor: HIPP THOMAS DR
IPC: B21D22/22
Filed: 1990-12-01
Abstract: The holding down appliance force is slightly larger than the sum of the force components to be expected, resulting from the tangential pressure tensions, being preset on the drawing part flange. The force is reduced at the beginning of the forming process and is increased slightly above the sum of the force components, when folds are initially formed. The force is again reduced, at the beginning of the growth of folds in direction of movement of the die.  The control process is repeated in a pulsating manner with high forces during deep drawing. USE - The process is to increase a deep drawing limit ratio for sheet metal material, with variation of the force of the holding-down appliance. It is esp. for manufacture of formed parts, the flange of which is cut off after deep drawing.
