Abstract: A vacuum valve or door having a closure plate for closing an opening in a wall. The opening has opposing first and second longitudinal edges and shorter opposing first and second transverse edges. A sealing unit seals the closure plate against the wall in the closed position. The sealing unit includes a supporting frame having opposing first and second longitudinal legs and shorter opposing first and second transverse legs, on which supporting frame there is mounted on one side a circumferential closure plate seal and on the other side a circumferential wall seal. The supporting frame is secured to fastening points on the wall, with central portions of the first and second longitudinal legs being free with respect to the wall, or the supporting frame is secured to fastening points on the closure plate, with the central being free with respect to the closure plate.

Abstract: The invention relates to a high-frequency grounding device (40) for use with a vacuum valve for closing and opening a valve opening of a vacuum chamber system, having a grounding band (42) made of a conductive material for discharging electrical charges occurring on the vacuum valve, wherein the grounding band has a first end (41) and a second end (43) and, for grounding the vacuum valve, is designed to be connected at the first end to a valve closure of the vacuum valve, and to be connected at the second end to a component of the vacuum chamber system, wherein the high-frequency grounding device has a correction impedance, wherein the grounding band is coupled to the correction impedance so that a resonant circuit results, which comprises the grounding band and the correction impedance, and the correction impedance has a first element for shifting a resonant frequency of the resonant circuit and/or a second element for reducing a quality of the resonant circuit.

Abstract: The invention relates to a solar power installation which is characterized in that the supports of the solar modules are stacked one above the other when in the “off” state and are extended by means of a transfer and lifting mechanism when in operating mode. The installation is also equipped with a controller which allows the installation to put the system into the safe off state in adverse conditions. The system is also advantageously suitable for stored energy sources and fueling electric vehicles.

Abstract: The invention relates to a solar power plant having a plurality of solar panels arranged in a row and at least one holding element on which the solar panels are held one after the other. The solar panels can be displaced along the at least one holding element with engagement means from an extracted operating position into a retracted resting position.

Abstract: The present invention relates to a device for the treatment of a workpiece, in particular of a substantially flat substrate, comprising a table (2) for supporting the workpiece (5), a flow generation apparatus (6, 11) producing a gas flow (22) on a top face (17.1, 17.2) of the table (2) in a region between the workpiece (5) and the top face (17.1, 17.2) of the table (2), on which gas flow the workpiece (5) is supported during the treatment.

Abstract: The invention relates to a solar installation (11) comprising a plurality of solar panels (19) that are suspended in a row between two supporting cables (15, 16). Anchor points (13, 14), at which both of the supporting cables (15, 16) are directly or indirectly anchored, is provided at least in front of and after the row of solar panels. A spacer (17) is provided at least between each row of solar panels (19) and the anchor points (13, 14), said spacers (17) maintaining the supporting cables (15, 16) at a pre-determined distance in relation to each other in the region of the rows of solar panels (19). At least one of the spacers (17) is mounted on a support (25) so as to be pivotable about a swivel axis (23), and a pivoting device (27) is provided to secure the spacer (17) and the support (25) at a specific pivoting angle in relation to each other. At least one intermediate fastening device is provided.

Abstract: A device for processing a usable surface extending on a usable side of a substrate (11) having a large surface area, particularly such having a length or width >0.5 m and a thickness <1 cm, through the substrate, has at least three bearing elements (21, 23, 25) disposed at a distance from each other for receiving the substrate (11), and a movable processing device for processing the substrate between the bearing elements from the rear of the substrate. The bearings support the substrate, and processing of the glass substrate can be carried out in the at least two intermediate regions between the bearing elements from the rear. At least one non-terminal bearing element is disposed displaceable or movable relative to the substrate in order to make the entire usable surface of the substrate accessible to the processing device by displacement or movement.

Abstract: A thin film silicon solar cell for use in photovoltaic cells having a carrier substrate, a front transparent conductive oxide contact, a thin film silicon solar cell layer having at least one layer of hydrogenated microcrystalline silicon or nanocrystalline silicon, and a back contact having a transparent conductive oxide contact layer and a back reflective layer comprising a white pigmented dielectric reflective media.

Abstract: An apparatus for manufacturing tiles by extrusion of clay or a similar material comprising a die adapted with a number of spaced apart pivotable rigid blades which are arranged such as to equalize the output speeds of several superposed layers of extruded material. Means are also provided substantially in the planes of the blades downstream of the outer ends thereof for projecting a pulverized powder product at right angles to the direction of extrusion into interstices between the layers. Impermeable coatings are added to the outer surfaces of the superposed layers and the assembly is then cut into piles of tiles which can then be delivered into an oven for baking, the heat ensuring removal of the impermeable coating and the separation powder product.
