Abstract: A method for the combined pump water pressure-compressed air energy storage at a constant turbine water pressure, the energy to be stored is used to pump a liquid medium into a pressure vessel such that a rising level of medium compresses the gas contained in the pressure vessel through a connecting conduit and presses said gas into a compressed gas tank, the conduit being shut using a check valve such that the energy is stored in the compressed gas.

Abstract: A device for surface-treating, coating or producing construction elements in a continuous process has production chambers arranged successively closely adjacent to one another in a direction of transport of the construction elements through the device. Each production chamber has opposed ends with through openings and is connectable to a vacuum source. Each production chamber has a stationary chamber part of reinforced concrete and a detachable chamber part of reinforced concrete connected to the stationary chamber part, wherein the stationary chamber parts have first edge areas and the detachable chamber parts have second edge areas, wherein the first and second edge areas have sealing surfaces sealing the stationary and detachable chamber parts relative to one another. Each production chamber has walls defining a hollow interior, wherein the walls consist of a metallic skin anchored in the stationary and detachable chamber parts, respectively.

Abstract: A method of manufacturing heat-insulating structural and/or light elements composed of at least two wall elements of glass, a glass alloy or metal, wherein the wall elements are separated from each other by support elements and are provided on at least one of surfaces thereof facing each other with a layer reflecting heat radiation, and wherein the structural and/or light elements further are composed of a deformable sealing element for connecting the wall elements to obtain a hollow space between the wall elements which can be evacuated or supplied with gas.

Abstract: For coating the glass edge of two wall elements (2, 3) forming interspace (5) for heat insulating structural and/or light element (1), metallic adhesive layer (4) is produced with the use of a physical (PVD) or chemical (CVD) deposition of the coating material from a gas or vapor phase on one side of each wall element (2, 3). On this adhesive layer (4) barrier layer (6) protecting the latter is deposited and the barrier layer is provided with subsequent solder layer (7). These solder layers (7) are bonded with sheet (8) that edges structural and/or light element (1) on the edge in a gastight manner.

Abstract: A building and/or light element includes at least two parallel wall elements (1) between which support elements (2) for the formation of an evacuated interspace (3) are placed and are connected by a flexible seal on the edge. The distance between the wall elements (1) is less than 0.5 mm and the support elements (2) are formed as disks lying flat between wall elements (1). The production and application of support elements (2) occurs with a punching device placed over the gridlike predetermined distribution surface of wall elements (2).

Abstract: A solar collector composed of at least one transparent, hollow evacuated cover tube having arranged therein at least one absorber, and a reflection layer at least partially covering the inner surface of the cover tube. The absorber extends over part of the inner diameter of the cover tube and has one or more fluid-conducting conduits or lines as well as a holder member supporting such lines or conduits which are provided with a selective layer. The individual cover tubes are arranged at a likewise evacuated collecting line or conduit.

Abstract: A vacuum tank or the like, especially for the storage of heat for a long period of time, comprising an outer pressure shell and an inner shell having an evacuated intermediate space. The pressure shell is formed of concrete and equipped with a metal covering bearing thereagainst. Support elements or anchoring means arranged at the metal covering are anchored in the pressure shell. The inner shell is formed of a compression resistant material.

Abstract: A main tow line carries deterrent scarecrow devices such as optical or acoustical devices. The tow line is supported by wire or rope-held pulleys secured to movably supported poles attached in the soil. The tow line is actuated by a drive assembly imparting a reciprocative movement to the main tow line by converting a rotary motion into a linear motion. The system can be operated by motive power which is controlled in accordance with prevailing light intensity conditions by a light sensitive control system. Auxiliary deterrent devices are attached to the poles, i.e. in the regions of the support of the main tow line to provide for protection particularly in corners, and coupled to the separate ropes for the pulleys to be moved thereby upon change of stress when the tow line reciprocates.

Abstract: A plurality of trays of substantially similar outline are stacked above each other. At least two elongated guide rods or posts are located at opposite sides of the carrier trays and extend perpendicularly through the trays, the guide posts being formed with folding joints, each, to permit folding them over when the trays are stacked tightly against each other, to serve as a carrying handle, while, upon erection, permit the trays to be slid vertically, with clearance, for access to the contents of the trays; the top tray is formed with a lock, engaging the upright posts to lock the top tray in position, when the posts are erected, the lock preferably including a spring-loaded, notched finger engaging a cross element or cross bar on the respective posts, which cross bar can hook into a locking eye on the topmost tray to lock the handles in position when folded, so that they can serve as a carrying handle for the entire tray assembly.
