Abstract: The invention relates to a method for cooling rising vapor (3) in a desorption column (2) by means of a condenser, which is situated at the head of the desorption column, is configured as an indirect heat exchanger and is traversed by a coolant (1). According to said method, the coolant enters at the bottom of the condenser (1) and flows upwards through conduits (8) that are arranged vertically in the condenser. The coolant is enriched with hydrogen sulphide prior to its entry into the condenser (1) and after the absorption of heat, escapes as an overflow (6) from the top of the condenser (1) through upper openings (10) of the conduits (8). The invention also relates to a desorption column (2) for carrying out said method.

Abstract: With the help of a method of selective removal of hydrogen sulphides, organic sulphur components and CO2 from crude gases, by using a first and second absorption stage (41 or 49) for separating almost pure CO2, a solution has to be found, with which, among other things, hydrogen sulphides and organic sulphur compounds can be removed in as selective a manner as possible. This is achieved as follows: the absorption agent coming out of the first absorption stage (41) and enriched with hydrogen sulphide and CO2 a.o.
Abstract: The invention relates to an adsorption filter for fuel vapors, particularly from the fuel tank of a combustion engine of a motor vehicle, which can be regenerated by desorptive reverse flow back flushing and which interacts with heat accumulating substances via the adsorbable or desorbable filter material. The aim of the invention is to increase the heat accumulability inside the filter material. To this end, the heat accumulating substances consist of phase-change materials (PCM) that are distributed in small units within the reactive filter material.
Abstract: The invention relates to an elastic laminate. The laminate is made from a co-extruded elastic film, comprising an elastomeric support layer, at least one cover layer and at least one textile outer layer made from a non-woven. The cover layer has a low layer thickness by comparison with the support layer. The outer layer is laminated onto the cover layer. According to the invention, the cover layer is made from an elastomeric material, with essentially the same expansion properties as the material of the support layer and contains additives for modification of the surface properties.

Abstract: Disclosed is a piston (1) for a combustion engine, comprising an annular grooved reinforcement (4) that is screwed onto an externally threaded (13) collar (12) located in the piston head area via an internal thread (19) which is mounted on the inside of the grooved reinforcement (4). The grooved reinforcement (4) blocks a recess (14) so as to form an annular, closed cooling duct (21). In order to provide the screwed connection between the collar (12) and the grooved reinforcement (4) with sufficient stability, a radially outward area of the collar (12) is equipped with a bend that points towards the hub. Furthermore, the collar (12) is embodied in an elastically resilient manner so as to bend in the direction of the piston head when the grooved reinforcement is screwed in, thus prestressing the screwed connection.
Abstract: A membrane-type coupling includes an input flange and an output flange which are interconnected via membrane packs in order to transmit torque in such a way that an input membrane pack is braced to the input flange, two output membrane packs that are connected in parallel are braced to the output flange, and the membrane packs are braced to one another with the aid of a clamping set composed of clamping rings. In order to reduce the volume and weight of such a membrane-type coupling, the input membrane pack is disposed between the two output membrane packs.
Abstract: The present invention relates to a camshaft (1) having cams (3 and 4) rotatable with respect to one another about the camshaft axis (2) over limited circumferential angles, whereby an inside shaft (5) and an outside shaft (6) are arranged coaxially one inside the other. The cams (3 and 4) that are rotatable with respect to one another each consist of first cams (3) and second cams (4), whereby the first cams (3) are fixedly connected to the inside shaft (5) and the second cams (4) are fixedly connected to the outside shaft (6), each by means of a fixation device (8). It is essential to this invention that the first cams (3) each have a first through-bore (11) which is aligned with a respective second through-bore (12) in the inside shaft (5) when the first cam (3) is installed. In addition, the fixation device (8) is formed by two essentially identical fixation pins (10 and 10?) with respect to their axial longitudinal extent.

Abstract: This invention relates to the use of hypo-oncotic aqueous solutions of molecularly dispersed chemically modified high molecular weight crosslinked hemoglobins, namely so-called hemoglobin hyperpolymers, to prepare agents for the symptomatic, primarily life-saving treatment of acute pulmonary edema. Administration in particular is intravascular. Surprisingly, additive administration can be performed since according to the invention the colloidal-osmotic (=oncotic) pressure of the blood itself is essentially raised only slightly, and the blood volume is increased hardly at all. Administration pursuant to the invention is thus (almost) volume-neutral based on the blood into which the injection is made. A hyperpolymeric hemoglobin derivative is thus used therapeutically for the first time as a blood additive for the treatment of pulmonary edema.
Abstract: The invention relates to a bed comprising a mattress with a plurality of air chambers arranged in a grid, each chamber being equipped with at least one air connection. The bed is also equipped with a plurality of controllable valves, each valve being assigned to one of the air chambers and several sensors. A control unit is connected to the sensors and controls the valves individually in accordance with the output signals of the sensors. In addition, the inventive bed comprises an air source that is connected to the valves.
Abstract: A combination of first and second connectors fittable with and detachable from each other is disclosed. The first connector comprises a first body, a guided portion and a stopper-releaser. The guided portion is held by the first body and is movable between a detachment position and a fit position via a preliminary-fit position when the first connector is fitted with or detached from the second connector. The fit position and the preliminary-fit position are within the second connector. The stopper-releaser accompanies the guided portion. The second connector comprises a second body, a lever and a lever stopper. The lever is provided with a guiding portion and is supported by the second body so that the lever is rotatable between first and second positions. The lever allows the guided portion to move between the detachment position and the preliminary-fit position when the lever is positioned at the first position.
