The invention relates to a device for protecting a photovoltaic plant (1) against damages caused by rodent bites. The inventive photovoltaic plant (1) comprises several components, including solar cells (2), a control unit (5), a power inverter (7), an internal power supply (13) and at least one microcontroller (9), which are interconnected by means of corresponding lines (3, 6, 8, 11). The aim of said invention is to develop a device which optimally protects against damages caused by rodent bites and is as simple as possible in terms of maintenance and mounting. For this purpose, an ultrasonic emitter (12) for transmitting ultrasound signals is provided and connected to the microcontroller (9) of the photovoltaic plant (1) in such a way that the transmitted ultrasound signal can be controlled and adjusted thereby.

The invention relates to a laminated unit (1) comprising at least one image layer (3) between at least two laminates (2). In order to glue the image layer (3) flat to the adjacent laminates (2), each side of said layer is provided with an adhesive intermediate layer (4, 4'). The two adhesive intermediate layers, each adjoining the image layer (3) and/or the laminates exhibit different thermal expansion behaviour, in such a way that the image layer (3) is held taut as a result of the inhomogeneous nature of the composite during changes in temperature. The invention also relates to a method for producing a laminated unit (1), according to which both sides of the image layer (3) are glued flat to the laminates (2) using adhesive intermediate layers (4, 4') and said intermediate layers (4, 4') and/or the laminates (2) exhibit different thermal expansion behaviour.
摘要:
Die Erfindung betrifft eine gekapselte, elektrische Maschine (1), vorzugsweise senkrecht eingebaute Asynchron-Traktionsmaschine, und einem Gehäuse (10), einem im Gehäuse (10) angeordneten Stator (4) und einer rotierenden Welle (5) mit einem darauf befestigen Rotor (6), wobei die Maschine gegebenenfalls für einen Zusammenbau mit einem Getriebe (2) vorgesehen ist, wobei die Lagerung getriebeseitig erfolgt. Zur Schaffung einer optimal gekühlten elektrischen Maschine (1), welche konstruktiv den gegeben Platzverhältnissen im anzutreibenden Fahrzeug angepasst werden kann ist vorgesehen, dass die Abführung der Verlustwärme durch natürliche Konvektion bzw. Strahlung und gegebenenfalls durch eine vom Fahrtwind erzeugte Konvektion erfolgt, wobei das Gehäuse (10) aus Leichtmetall, vorzugsweise Aluminium hergestellt ist und das Gehäuse (10) außen diagonal gegenüberliegende Kühlrippen (3) aufweist. Die Kühlrippen (3) sind vorzugsweise überlang ausgebildet, d.h. weisen eine Länge auf welche ein Vielfaches der Dicke der Kühlrippen (3) und der Abstände der Kühlrippen (3) zueinander beträgt.

The invention relates to a carrying or guiding device (1) for aircraft components, especially for a landing flap which is arranged on an aircraft wing. The inventive device comprises a carrier (2) having an essentially U-shaped profile and essentially parallel lateral walls (3, 4). In order to produce one such device in such a way that it weighs as little as possible, has the required mechanical properties, and is as easy to produce and to assemble as possible, the carrier (2), and preferably one covering plate (20) arranged on the open side of the carrier (2), are produced from fibre reinforced plastic, especially carbon fibre reinforced plastic (CFRP). The connection between the carrier (2) and the covering plate (20) and possible connection elements (21) is preferably carried out by means of glued joints and, if necessary, additional riveted joints or screwed joints.

The invention relates to a system for purifying exhaust gases, comprising at least two filter stages (1, 2, 3), including at least one filter stage (1) for purifying the exhaust gases from particulate and aerosol-containing substances, and at least one filter stage (2) in the form of a biological filter for purifying the exhaust gases from organic compounds, aerosols and other odor-intensive substances by means of microorganisms. The second filter stage comprises a mass transfer zone (9) in which the exhaust gases are transformed from the gas phase to the liquid phase by the atomization of wash water. The aim of the invention is to provide a simple and inexpensive system with which high purification rates can be achieved. To this end, at least one filter stage (1, 3) is configured as a spray tower or wet electric filter using wash water, and the system is provided with means for maintaining a constant temperature in the thermophilic temperature range of from 45 °C to 75 °C in the filter stage (2) that is configured as a biological filter.
