Title: Apparatus and method for the fine corrugation of sheet metal, and corrugated sheet metal
Inventor: MACK ERNST
IPC: B21D13/04
Filed: 1989-02-11
Abstract: An apparatus for the production of corrugated thin sheet metal has two rotatable shaped bodies (8, 9) which mesh with one another without making contact and the corrugation ridges and corrugation grooves of which define a corrugation gap (20) which is at least as large as the thickness of the metal sheet (2) to be corrugated in all rotational positions. The position and shape of the corrugation ridges is chosen so that the uncorrugated portion (3) of the metal sheet (2) can be fed in sliding fashion into the corrugation gap (20) during the bending of the respective corrugation trough and, as a result, the metal sheet (2) is not subjected to any bending deformation or any other deformation in the region of the flanks (7) of the corrugations. This gives a method in which the sheet metal is corrugated by bending only in the region of the apical curvatures (6) and the corrugated sheet metal is thus composed of unformed and therefore relatively easily deformable or non-work-hardened material in the region of the flanks (7) of the corrugations. <IMAGE>

Patent DE-3908068-A1 (DE)
Title: Method for producing interconnects on a substrate panel for liquid-crystal cells
Inventor: BROSIG STEFAN DR
IPC: G03F7/00
Filed: 1989-03-13
Abstract: In the case of a method for producing interconnects on a substrate panel for liquid-crystal cells, a short-circuit test is carried out even when there are still photoresist tracks on the interconnects. The photoresist tracks are not removed until after the short-circuit test. In the case of known methods, on the other hand, the short-circuit test was not carried out until the entire production process for the interconnects had been completed. The procedure according to the invention has various advantages. One is that the interconnects are still mechanically protected by the photoresist tracks located over them during the short-circuit test. A further, very significant advantage is that the already existing photoresist material can be used to allow rectification of short circuits in a simple manner. Specifically, if short circuits are detected, the short-circuit points are located and the interconnect is exposed in this area by removal of the photoresist, the short-circuiting area of the conductive layer then being locally removed. The photoresist tracks are not removed until this has been done.

Patent DE-3923906-A1 (DE)
Inventor: KARIMI-RAD HOUSHANG DIPL ING
IPC: F01C1/073
Filed: 1989-07-19
Abstract: The invention concerns an internal-combustion engine which operates as follows: If the inner cylindrical shell (2) rotates clockwise, the volumes of the cylinders (3) increase or decrease together in pairs. If the inner cylindrical shell (2) rotates through 90 DEG , the two locked-in pistons (4) rotate together with it through 90 DEG . These pistons then impact with the resting pistons (4) in front of them in the outer cylindrical shell (1). At this moment, the rigid bolt (13) in the moving pistons impacts with spring mounted bolt (19) in the resting piston (the same happening in the other direction). This causes the lock-in plate (11) of the resting piston to lock into a recess (12) in the inner cylindrical shell (2), and the piston starts moving with the inner cylindrical shell (2). The moving piston then locks into the outer cylindrical shell (1) and remains stationary at 90 DEG . This procedure is continuously repeated in pairs, thus giving the four established strokes: aspiration, compression, explosion and exhaust. Two explosions occur for every 360 DEG  [one complete revolution of the inner cylindrical shell (2)], the two explosions taking place simultaneously at 90 DEG  and 270 DEG  (12 o'clock and 6 o'clock), the aspiration inlet and exhaust outlet being located at 0 DEG  and 180 DEG  (9 o'clock and 3 o'clock).
