20150332878 | POWER CIRCUIT BREAKER - The invention relates to a power circuit breaker that is suitable for switching electrical voltages. The power circuit breaker according to the invention comprises two main electrodes, to each of which a respective pole of the voltage to be switched can be connected. During the switching process, at least one of said main electrodes follows a switching path. The power circuit breaker is characterized in that secondary electrodes are additionally provided, which protrude into the vicinity of the switching path and are designed and arranged in such a way that arcs can be produced (a) between the main electrodes and the secondary electrodes and (b) between the individual secondary electrodes during the switching process. The power circuit breaker according to the invention can be advantageously used in vehicles and in ultra-high-voltage AC and HVDC (high-voltage direct current) transmission systems and causes arcs to be extinguished as early as possible during the switching process. | 11-19-2015 |
20150198674 | METHOD AND APPARATUS FOR DETERMINING THE STATE OF BATTERIES - The present invention relates to a method and a suitable apparatus for determining the state of a rechargeable battery and for checking contact resistances in a battery system. According to the invention, an impedance curve is determined using signals at different frequencies and a value for an area, which results from the impedance curve, is then calculated from a predetermined threshold value and an x axis. The value for the area is a measure of the ageing of the battery. A control signal is generated on the basis thereof. In one preferred embodiment, said control signal is used to drive a signaling apparatus and thus to present the state of the battery to a user. The present invention can be used, for example, in motor vehicles that are electrically driven. | 07-16-2015 |
20140015725 | METHOD AND ARRANGEMENT FOR MODELING ANTENNA EMISSION CHARACTERISTICS - A method and an arrangement for modeling antenna emission characteristics are disclosed. | 01-16-2014 |
20120010227 | FORMULATION FOR NAIL AND NAIL BED DISEASES - The invention relates to a pharmaceutical composition with a content in active ingredient that can be an antimycotic, so that the composition is suitable for the treatment of onychomycoses, in particular severe onychomycoses. The inventive formulation is an ointment-like thermogel at body temperature and an inviscid thermogel at lower temperatures and facilitates the permeation of sufficient active ingredient quantities through human fingernails and toenails, in order to also treat severe onychomycoses. | 01-12-2012 |
20100310630 | COATED SURFACE FOR CELL CULTURE - The invention makes available a keratin coating of a support substrate and a method for the production thereof. This keratin coating is suitable particularly for the in vitro or in vivo culturing of epithelial or endothelial cells and, because of its optical transparency, for microscopy. The keratin coating is prepared by applying or coating keratin in the form of nanoparticles from an aqueous keratin solution or keratin suspension. The solution or suspension does not contain any reducing compounds. The keratin solution is prepared preferably from hair, such as human hair. For the preparation of the coating, keratin is brought into solution or into a suspension of nanoparticles by mixing the keratin with an aqueous composition which contains thiourea, urea, and mercaptoethanol. | 12-09-2010 |
20100145050 | ORTHOGONALLY FIXED COMPOUNDS FOR ELECTROOPTICAL APPLICATIONS - The present invention relates to chemical compounds that can be used in electrooptical applications. The electrically conductive and optical properties of these compounds, e.g. hole transporting, electron transporting and/or light emitting properties can be predetermined by substituting the core structure of these compounds with respective residues. The core structure ( | 06-10-2010 |
