Patent EP-0353479-A1 (EP)
Inventor: RUESCH PETER
IPC: B21D28/00
Filed: 1989-07-05
Abstract: The stroke of the ram (2) is limited by at least one positive stop (5, 6). At least one positive stop (5, 6) has at least one sensor (15) which determines the resilient deformation of the respective stop (5, 6) resulting from the impact force. The output signals of the respective sensor (15) are fed to the control device for the ram height adjustment. This ram height adjustment is carried out by a servomotor (9) and adjoining gear train (10). By means of the positive stops (5, 6), the bottom dead centre of the ram (2) relative to the lower tool part can be set according to the requirements. In this way, it is also possible to define exactly the plunging depth of the upper tool part (3) with the stampers (8) into the lower tool part (4), and it can also be zero or less. The ram height, which can be corrected depending on the impact force on the positive stops (5, 6), reduces the press load, which would otherwise increase greatly in line with the increasing number of strokes. …<IMAGE>…

Abstract: The invention relates to a container-draining device (1), comprising a connection piece (2) which is to be arranged on a container wall and has a passage opening (3) which leads, on the outside, into an angularly extending draining channel (5) which is formed in a tubular piece and on one side has an outlet opening (6) to which is connected, toward the other side (7), a slightly conical and then, following the larger diameter, a cylindrical (8) channel part, and into which draining channel an insert (9) with at least one corresponding conical part (10) is inserted and can be positionally displaced by means of a connecting-link guide (11, 22) by a rotary movement in the longitudinal direction, to open and close the passage opening. Draining devices of this type must remain absolutely leaktight even when used frequently, without becoming expensive to manufacture. This is achieved in that, in the vicinity of the smallest and in the vicinity of the largest diameter of the conical region, in each case one sealing lip (16, 17, 18) which projects radially beyond one of the opposing outer surfaces is provided, for bearing on the respective opposed face of the surfaces at least in the closed position.

Abstract: Bei einer Schnellschlussklappe, bei welcher das Öffnen durch einen hydraulischen Antrieb erfolgt und das Schliessen durch eine Feder eingeleitet wird, sind zwei unabhängige Systeme vorgesehen, nämlich ein Servosystem (1) und ein Klappentellersystem (2), die miteinander über eine Kupplung (1a, 2a) verbunden sind. Die Kupplung selbst weist zwischen dem servoseitigen Kupplungsteil (1a) und dem klappentellersystemseitigen Kupplungsteil (2a) einen Freilauf auf, der ermöglicht, dass die beim Aufschlag des Klappentellers (14) auf den Sitzring im Klappengehäuse (9) auftretenden Kräfte aufgeteilt werden, entsprechend der kinetischen Energie der bewegten Massen eines jeden Systems (1, 2). Der Freilauf verteilt somit die Beanspruchung auf zwei Schläge hintereinander, womit die Spannung im Hebel (12) des Klappentellers (14) annähernd um die Hälfte reduziert wird. Eine hydraulische Bremse im Servosystem (1) sorgt dafür, dass die Schliessgeschwindigkeit des Klappentellers ca. im letzten Drittel des Schliessvorganges konstant gehalten wird.

Abstract: A novel process is provided for fabricating transistors (14), contacts (46s, 40g, 46d) and interconnections (46c) in a novel self-aligned configuration. The process of the invention permits higher packing densities, and allows feature distances to approach 0.5  mu m and lower. In a preferred embodiment, the configuration is also planarized. A unique combination of masks in conjunction with a multi-layer structure (28) formed on the surface of a semiconductor wafer (16), the multi-layer structure including a buried etch-stop layer therein (28b), defines the source (18), gate (22), and drain (20) elements and their geometry relative to each other and to interconnects. Polysilicon plug (40, 46) contacts through slots in the multi-structure layer permit vertical contact to be made to the various elements. Silicidation (56) of the polysilicon plugs reduces series resistance in the vertical direction and permits strapping of N<+> and P<+> polysilicon plugs.

Abstract: Two lap webs (I, II) lying one on the other are respectively fed continuously to the combing tools (1, 2, 3, 4, 5) in a plurality of combing heads of the machine. The first lap web (I) comes from a first lap roll (7) carried on a rear supporting device (8, 9) and runs over a front supporting device (11, 12). This carries a second lap roll (10), from which the second lap web (II) comes. A detector determines when the end of the lap web (I) runs off from the first lap roll (7) in one of the combing heads. A control device then executes a roll change simultaneously for a plurality of combing heads as follows: the end of the first lap web (I) is severed to the same length in all the combing heads. The severed lap-web remains and the winding tubes of the first lap rolls (7) are removed. The second lap rolls (10) are rolled onto the rear supporting devices (8, 9). New lap rolls (24) are so deposited onto the front supporting devices (11, 12) that the start (A) of the lap web of these rolls (24) is aligned with the end of the first lap web (I). The roll change can thus be carried out fully automatically and without the combing machine being stopped.
