Patent EP-0039952-A1 (EP)
Inventor: HEBENSTREIT ERNST DIPL-ING
IPC: H03K17/687
Filed: 1981-05-12
Abstract: A switch includes an MIS-FET having a source and a control electrode defining a gate-source capacitance and being operated as a source follower for switching a given voltage, a first capacitor, a first auxiliary transistor and a second auxiliary transistor cutting off the first transistor when switched into a conducting state. The transistors each have a base, a collector and an emitter electrode defining a switching path. The collectors of each of the transistors are connected to the control electrode of the FET. A control input terminal is provided as well as second and third capacitors each being connected between the control input terminal and the base of a respective one of the transistors. The emitter electrode of the second transistor is connected to the source electrode of the FET. The first capacitor has one lead connected to the emitter electrode of the second transistor and to the source electrode of the FET for charging the gate-source capacitance of the FET through the switching path of the first transistor, and another lead connected to the emitter electrode of the first transistor and to a terminal of a voltage source having a lower voltage than the given voltage to be switched by the FET for charging the first capacitor when the first transistor is cut off.

Abstract: Alphagipshalbhydrat ist ein wichtiger Baustoff, der insbesondere durch Calcinierung des Calciumsulfatdihydrates gewonnen wird, das bei der Rauchgasentschwefelung von Kraftwerken oder im Chemiebereich beispielsweise bei der Phosphorsäureherstellung anfällt. Ein besonders günstiges Calcinierverfahren besteht darin, daß zunächst eine Dispersion aus Calciumsulfatdihydrat und wässriger, schwefelsaurer Lösung in Gegenwart von schwefelsauren Salzen hergestellt und diese dann unter Einhaltung einer vorbestimmten Aufheizgeschwindigkeit auf etwa 373 K mit industriellem, staubfreiem Wärmemüll aufgeheizt wird, worauf hin dann die festen Bestandteile von der wässrigen Schwefelsäure abgetrennt und getrocknet werden. Bei diesem Verfahren wird durch die Kombination von wässriger, schwefelsaurer Lösung und schwefelsauren Salzen ein Alphagishalbhydrat praktisch ohne Anteile von Anhydrit II erreicht, was dessen Verarbeitung wesentlich erleichtert. Neben dem vernachlässigbar kleinen Anteil von Anhydrit zeichnet sich das Alphagipshalbhydratprodukt bei Zugabe von Magnesiumoid durch eine hohe Feinheit und keinerlei Ausblüherscheinungen aus.

Abstract: This invention relates to blind fasteners and more particularly to blind fasteners having a large bearing surface on the blind side of the structure on which it is mounted. Prior art fasteners either tend to damage the material on which they are mounted, have too small of a blind side bearing surface, or are too long to be used in certain applications. The fastener of the present invention has a nut (21) with an axial bore (23) therethrough, a conically shaped nose (24) at one end and an enlarged head (26) at the other end. Extending through said nut is a bolt (30) having a stem (31) and an enlarged head (32) adjacent to said nut nose (24). Between said nut nose and said bolt head is a sleeve (40) on said bolt stem. The improvement of the present invention comprises said sleeve having a thick wall (41) section adjacent to said bolt head and a thin wall section (42) adjacent to said nut nose and a collar (50) which engages said sleeve and which has a tensile strength very much less than the tensile strength of said sleeve.

Abstract: Appareil (2 ou 3) destine a faire sauter un objet mobile (10) d'un endroit a un autre. Les domaines d'application comprennent la protection d'installations sous-marines telles que les pipelines (1) et les cables, contre les degats provoques par le derapage d'ancres (10) et attirails de peche. L'appareil comprend un dispositif en forme de plaques (2 ou 3) qui est stable par rapport a une force horizontale sur une certaine plage de resistance. La deformation du dispositif (2 ou 3) due a cette force horizontale se traduit par une direction plus abrupte de la resultante (14) agissant sur le bord (6). La resistance de friction combinee a la pression passive du sol (7) est alors capable de supporter la force horizontale de l'objet mobile (10). Par consequent, le dispositif (2 ou 3) portant l'objet (10) tournera autour du bord (6) et soulevera l'objet (10) par dessus l'installation (1). Plusieurs autres conceptions du dispositif (2 ou 3) et un procede d'installation sont decrits.

Abstract: A multiple clip applier including a handle and a cartridge which holds a large number of ligating clips and which snaps into a cartridge-receiving channel on the handle. The handle operates like an elongated scissors with scissors handles at one end and jaws at the other to which clips may be delivered in rapid succession. Opening and closing the scissors handles operates the mechanism of the handle to open and close the jaws and to provide a long stroke motion for delivering clips from the end of the cartridge to the nose section. Clips may be indexed through the cartridge by reciprocating parts of the cartridge with respect to one another with a short stroke cocking motion captured from the long stroke delivery motion from a cooperating slot and pin mechanism. These two motions are accomplished within the envelope of motion of the normal opening and closing of the scissors handles to operate the jaws of the applier and to feed and index clips from the cartridge to the nose. The mechanism of the present invention permits the overall shape of the handle to be small, compact and readily adaptable for use even deep in an incision site.
