Abstract: The invention relates to a packing assembly for a material exchange column, comprising at least one structured packing plate and a container in which the at least one structured packing plate is arranged. The at least one structured packing plate has packing packets. Each packing packet has interconnected packing sheets. The packing sheets are corrugated and have corrugation peaks and corrugation valleys. Adjacent packing sheets contact each other at the corrugation peaks. Additional corrugated packing sheets are added between the packing packets such that the at least one packing plate is pretensioned against the container in a radial direction thereof. Both the corrugated packing sheets of the packing packets as well as the additional corrugated packing sheet added between the packing packets are arranged solely on a common preferred plane or parallel thereto.

Abstract: The invention relates to a device (column) for bringing about a phase contact between a liquid phase and a gaseous phase, in particular a material exchange column, comprising: a shell, which extends along a longitudinal axis and bounds a shell space, at least a first circular tray, arranged in the shell space, for taking up the liquid phase, which extends crosswise to the longitudinal axis, whereby the at least one first tray has through openings for passage of a gaseous phase, so that the gaseous phase can come into phase contact with the liquid phase that is located on the at least one first tray. According to the invention, a large number of sealing weirs projecting from the first tray along the longitudinal axis are provided, which extend in each case along a radial direction of the at least one first tray, so that the first tray is divided into a corresponding plurality of sectors. In addition, the invention relates to an apparatus comprising such a device and a floatable carrier.

Abstract: The invention relates to a column (1), with a section (9), in which a filling (10) is arranged in the form of a large number of fillers or a packing, a liquid distributor (100) for distributing a liquid (F) on that filling (10), a distribution space (101) of the liquid distributor (100), via which the liquid (F) can be distributed to that filling (10) of the column (1). According to the invention, it is provided that in the distribution space (101) of the liquid distributor (100), an additional means (20) is arranged, which forms a large number of passages (21) for the liquid (F) that is to be distributed.

Abstract: A collector-distributor combination in a column, which is filled with a random packed bed or with a structured packing, is disclosed. The liquid phase is guided over a collector with inclined planes to a central opening, which is connected to an ascending pipe, from which the liquid phase is distributed to the plane underneath via the distributor pipes. By guaranteeing a constant filling level of the liquid phase in the ascending pipe, the distributor functions as a pressure distributor. The liquid phase is distributed independent of the inclination of the column over the entire length of the distributor pipes. The gaseous phase passes through the collector via the chimney.

Abstract: The compounds of structural formulae (I) and (II) and use of the compounds and salts and hydrates thereof, as therapeutic agents, is disclosed. A compound of formula (I) or (II) is an agonist for the &mgr; and &dgr; opioid receptors, an antagonist for the &kgr; opioid receptor, and has high affinity at all three receptors. A compound of formula (I) or (II) has utility in a variety of therapeutic and research areas where &kgr; opioid receptor antagonism is beneficial, including the treatment of opiate addiction or pain, or in a method of stimulating an immune system of a human.

Abstract: A stereotactic adapter on which a surgical therapeutic and/or diagnostic instrument is reproducibly mounted and attached to a surgical microscope that can be positioned in several spatial degrees of freedom. A position recognition system integrated in the surgical microscope permits safe positioning of the instrument used, given the geometric arrangement and the geometric dimensions of the surgical microscope, the adapter, and the instrument.

Abstract: In an arrangement of solenoid valves, a central plug and a printed circuit board on a control housing of a shift device of a toothed-wheel variable-speed gearbox, the printed circuit board which secures the central plug via a receptacle is clamped in directly on the control housing with the involvement of retainers for the solenoid valves.

Abstract: A device is provided for influencing starting of an internal combustion engine of a motor vehicle that has an electronically controlled gearbox, an electrically acting interlock that prevents the internal combustion engine from being put into operation when a gearbox status causing a driving force connection is selected, and a starter with an electromagnetic disengagement switch that is suppliable with battery current from an ignition switch during actuation of the starter. The device has an electronic engine control unit for at least one of ignition and metering of fuel, with a communicative connection communicatively connecting the engine control unit to the gearbox control. A direct connection is provided from the ignition switch to the electromagnetic disengagement switch for supplying battery current to the electromagnetic disengagement switch without an intermediate disabling switch.

Abstract: In a pressure-regulating arrangement for the control pressure of a shifting arrangement of a change-speed transmission, a slide valve member is actuatable by an adjusting sleeve connected with a control member of a driving engine by way of a pressure member. A hydraulic damping device with two mutually relatively movable damping parts of the piston-cylinder-type construction is provided in which one damping part is adapted to be supported with respect to the housing and the other is actuatable by way of the pressure member and damping medium is thereby displaced against the action of a throttle.

Abstract: A guide device for guiding a movable part of an apparatus relative to a fixed part of the apparatus, includes a first guide rail adapted to be provided on the movable part and a second guide rail adapted to be provided on the fixed part. Bearing means comprising a plurality of roller elements disposed in a roller support is disposed in a longitudinal groove between the first and second guides and movable relative thereto. Biasing means is provided which biases the bearing means toward a predetermined position.

Abstract: Contraceptive method comprises maintaining in the genital tract of a mammal an ester of 4-guanidinobenzoic acid and certain substituted phenols in a concentration effective to inhibit the fertilization of ova. In addition to effectively inhibiting the enzymes necessary for conception, the compounds used in the method of the invention are advantageous in possessing low toxicity. Further, the phenolic materials which may be liberated on hydrolysis of the 4-guanidinobenzoates in the genital tract of the animal are low in toxic, caustic or irritating properties, so that the contraceptive compositions are suitable for long-term use without adverse side-effects.

Abstract: A vent cap for a container of housing which accommodates a hydraulic operating medium. The vent cap includes a housing type cover which has labyrinth walls. The cover is adapted to be closed by a base insert which includes a vent passage. The vent cap is adapted to be mounted on a vent opening of the container or housing. The housing type cover is rotatably mounted on the base insert.

Abstract: A locking cap for an oil gauge pipe which includes a gauge rod mounted thereon, with the gauge rod being adapted to be inserted into the oil gauge pipe. An eccentric level arrangement is provided for locking the locking cap at the oil gauge pipe while a sealing ring is pressed between the locking cap and a flange of the oil gauge pipe. The eccentric lever is mounted on the locking cap and, in a locking position, reaches under the flange of the oil gauge pipe. In a locked position, the locking cap rests against the flange with the sealing ring being interposed between an inner surface of the locking cap and the flange.
