Patent EP-0029164-A1 (EP)
Inventor: MATTHAUS GUNTHER
IPC: H01B17/28
Filed: 1980-11-04
Abstract: Eine Hochspannungsdurchführung kann mit auf Hochspannungspotential und auf Erdpotential liegenden Leiterteilen sowie eine dazwischen angeordneten Isolationskörper versehen sein, der aus isoliertolien gewickelt ist, elektrisch leitende, innerhalb des Isolationskörpers endende Potentialsteuereinlagen enthält und gegebenenfalls von einem Isoliermedium getränkt ist. Bei einer solchen Hochspannungsdurchführung sind die Teilentladungs- und Stoßspannungsfestigkeit wesentlich durch die axiale elektrische Feldstärke an den äußeren Kanten der Potentialsteuereinlagen begrenzt. Die Erfindung sieht deshalb vor, daß als Potentialsteuereinlagen Doppelschichtfolien (7, 10) mit jeweils einer Schicht (14) aus elektrisch leitendem Material und einer Schicht (15) aus einem isolierenden Material mit einer hohen Dielektrizitätskonstanten εr vorgesehen sind und daß die Doppelschichtfolien (7, 10) an ihren den äußeren Begrenzungsflächen (4) des Isolationskörpers (3) zugewandten Seiten so zu Kanten (17, 18) gefalzt sind, daß jewels die isolierende Schicht (15) die elektrisch leitende Schicht (14, 18) umschließt. Als Doppelschichtfolien (7, 10) können insbesondere mit Aluminium kaschierte Folien aus einem Kunststoff vorgesehen werden.

Abstract: A process for producing aziridine-2-carboxylic acid or its salts is provided which comprises treating an alpha-halogeno-beta-aminopropionitrile or its mineral acid salt with an alkali or alkaline earth metal hydroxide in water or in a water-containing organic solvent. In a preferred embodiment, aziridine-2-carboxylic acid or its salt is produced by treating the reaction mixture containing an alpha-halogeno-beta-aminopropionitrile obtained by reacting an alpha, beta-dihalogenopropionitrile or an alpha-halogenoacrylonitrile with ammonia, with an alkali or alkaline earth metal hydroxide in the presence of water without isolating the alpha-halogeno-beta-aminopropionitrile from the reaction mixture beforehand.

Abstract: A pilot valve for assisting operation of a main valve to cause the main valve to open at a predetermined input pressure, comprises a diaphragm (3) of which one face (32a) is permanently subject to input pressure. The other face (3b) defines a space (8) with a valve member (7) which is in communication via a restricted passage (15) with input pressure and is connectable by a passage (16) to the main valve. The valve member (7) seats on a seat provided in a wall (5) and its other face (7a) is subject to constant pressure. When the input pressure increases above a set level,the valve member (7) will open against a biasing force placing the space (8) in communication with atmospheric pressure. Atmospheric pressure is communicated by passage (16) to the main valve causing main valve to open. The valve member will be held in its open position until input pressure has dropped below the set pressure closing the main valve.

Abstract: A collecter (10) for use in a cylindrical shaped chemical process tower (11) wherein it is desired to collect and/or redirect the flow of liquid flowing down the tower's internal wall surface (13), which requires no bolting orwelding to the tower and which affords a liquid seal with the tower wall. The collector comprises flexible annular segments (26,28,30,32) of slightly less radius of curvature than the tower, said segments being in near end to end relationship with each other so as to take the shape of a horizontal segmented ring with small gaps (50) between the segments. The flexible segments are spread apart in the tower by spreading means (52) connecting the ends of the adjacent flexible segments until these segments sufficiently conform to the tower wall (13) to form both leak-proof seals and friction joints thereinbetween. Liquid flow along the tower wall in the gaps (50) between the segments is prevented by bridging lips (56) attached to the segments and spanning the gaps (50) while also forming a leak proof seal against the tower wall.
