Abstract: A lubricant varnish component and a lubricant varnish, in particular for coating elastomer profiles, are proposed. The lubricant varnish component contains a polyurethane, a siloxane as well as a polyamide powder, a polyethylene powder or a solution of a polyamide. The lubricant varnish may additionally contain a curing agent, in particular an isocyanate-based curing agent. In addition, a first method for coating elastomers is proposed, the proposed lubricant varnish first being applied in the form of a coating to an elastomer profile, and this coating then being dried and/or thermally crosslinked. Furthermore, an alternative, second method is proposed, the proposed lubricant varnish, having or not having polyamide or polyethylene, first being applied in the form of a first coat to the elastomer profile, and an alcoholic or aqueous solution of a polyamide in the form of a second coat or a polyamide powder or a polyethylene powder then being applied to the first coat.

Abstract: An optical sensor is provided for determining a physical and/or chemical parameter of a sample, having at least one optical transmitter and at least one optical receiver, and having a sensitive element which is arranged in a beam path between the transmitter and the receiver and is exposable to the sample, and which changes its absorption and/or its refractive index for electromagnetic radiation of a specific wavelength in response to a change in parameters of the sample, in particular, a gas-sensitive element, and possibly having an evaluation unit arranged downstream of the receiver. The transmitter and the receiver can be coupled to the sensitive element via at least one optical waveguide. Provision is made for the transmitter (12) and for the receiver (14) to be coupled to the sensitive element via at least one optical waveguide (26, 28).

Abstract: The invention relates a method and a device for regulating individual sub-flows of a conveying system while the main flow is conveyed in a constant manner. The aim of the invention is to provide a method and a device which enable the sub-flows of the conveying lines of a system for conveying fluid media to be regulated as required in said individual conveying lines with just one conveyor unit. To this end, the inventive device for regulating individual sub-flows of a system for conveying fluid media has several conveying lines which are guided in parallel. The invention is characterized in that the following are arranged in the conveying system: at least one total pressure measuring device (10), at least one sub-flow measuring unit (D) in each conveying line, at least one valve (7) with a throttle (B) and a data acquisition, processing and control value output module (C), these being functionally interconnected by hardware and/or software.

Abstract: The object, in a device and a method for separating a shaped substrate from a stamping tool, is to make demolding more functionally reliable and to substantially prevent damage to expensive components. A closeable chamber, the mutually moveable chamber parts of which are the support for the stamping tool and for the shapeable substrate, contains a substrate holder which, when the chamber is closed, fixes. the substrate to its support outside the stamping area, with the result that the substrate is detached from the stamping tool when the chamber is opened. The device and method can be used for the production of microengineered components.

Abstract: A sensor element or an actuator element, in particular for use in motor vehicles, has an anti-adhesive surface coating as a protective layer, to reduce an accumulation, for example, of dirty water, mineral oil, silicon oil, soot, salts, hydrocarbons, dust particles or a combination of at least two of these substances. The surface coating is particularly temperature-stable, firmly adhering, and has a low surface energy. It contains at least one compound, selected from the group of fluorinated polymers, fluorormocers, of the polymeric fluorocarbon resins, of the fluorine-containing silanes, or of partially fluorinated polymers.

Abstract: The invention relates to an electrolyzer for the electrolysis of water in hydrogen and oxygen with a number of electrolytic cells, each containing an anode and a cathode, connected in series in a cell block surrounded by a pressure vessel. At one end of the cell block is a first electrode, and at the opposite end of the cell block is a second electrode. Both are connected with leading-in cables, which run through the pressure vessel and conduct the electric current to the cell block, the interior of the pressure vessel being filled with pressurized water surrounding the cell block. In accordance with the invention, it is envisaged that the first electrode is placed inside the cell block so as to be electrically isolated, by encapsulation, with respect to the pressurized water, and that there is a channel, sealed against the pressurized water, that leads from the cell block through the pressurized vessel to the outside.

Abstract: The apparatus and process to compensate for variations in thickness of molding tools and of moldable materials used in an embossing process to be carried out under a vacuum, while ensuring high dimensional stability, and to ensure different molding depths. For achieving this object, a chamber is employed having a pair of oppositely lying chamber parts, of which one is fixed to the framework and the other is adjustable, having side walls which comprise an inner part and an outer part. The inner part is fastened to the fixed chamber part and the outer part, on the outwardly facing end face to of which the adjustable chamber part comes to bear against the force of a spring during the closing of the chamber, is displaceable along guide elements on the fixed chamber part between two stops.

Abstract: A device for manipulating a synchrotron beam bundle is intended to produce properties of the beam bundle, under vacuum conditions, which are adapted to the respective application of deep X-ray lithography, in particular, which are adapted to the scanning regimen. Pairs of diaphragms which are displaceable relative to one another are provided between the object table and an inlet window within a vacuum chamber containing an object table for receiving an object to be irradiated, which object table is adjustable by a scanning movement relative to the synchrotron beam bundle. The pair of diaphragms for which the direction of relative displacement of the diaphragms coincides with the scanning movement is coupled with the scanning movement. Further, a filter chamber is arranged upstream of the vacuum chamber and contains filters which can be inserted into the synchrotron beam bundle.
