摘要： The invention relates to a volume-modified casting compound based on a curable epoxide resin or a mixture of such resins, comprising an epoxide resin, a curing agent, optionally an accelerator and further additives such as fillers, flexibilizers and dyes. Said casting compound contains (a) a three-dimensionally cross-linked polysiloxane in a dispersed form and with a particle size in the range of from 0.02 νm to 50 νm which optionally carries reactive groups capable of chemically reacting with the epoxide resin and/or the curing agent, (b) a selected linear or branched siloxane compound that carries reactive groups capable of chemically reacting with the epoxide resin and/or the curing agent, and optionally (c) a low-molecular oligomeric siloxane compound. The invention further relates to the use of the inventive casting compound as a construction material or as an insulating material, and to the shaped parts and insulations produced therefrom.

摘要： Mold-free resin-insulated coil windings are obtained by applying continuous fibers (4) embedded in a quasi-solid-state epoxy-resin matrix, e.g. in the form of a tape (2; 2a, 2b), to the coil windings (3). The tape (2; 2a, 2b) is locally heated up to the melting point of its polymer matrix, and is subsequently pressed against the winding body (1). The heated and fused resin of the tape (2; 2a, 2b), which is pressed onto the coil (1), flows under pressure into the voids and gaps between the coil windings (3) and fills them up, thereby hermetically insulating the coil windings (3). After leaving the heating and pressing apparatus (7, 5) the fused epoxy resin becomes solid again. The resulting curing process is thus considerably simplified and shortened, compared to the state of the art.

摘要： The invention relates to a circuit breaker, comprising a fuse unit (6) with a fusible element (7) made from a conducting material (8), such as Ag, Cu or Al, provided with a series of regularly spaced doping sites (9). The conducting material bears a layer of a first compound (10) in direct contact on the above sites, said compound containing a doping material such as In or Ge and forming mixed crystals, which contain the conducting material (8) and the doping material in a fixed stoichiometric ratio such as Ag2In, for example, and is separated from the first by a stable phase boundary. The doping sites (9) weaken the fusible conductor by lowering the melting point to beneath 250 DEG C, such that an arc is quickly formed on a short circuit occurring, even though the electrical resistance per unit length thereof is possibly only a few percent greater than in the other region. The fusible element (7) has a continuous coat of an inflammable material (12), with an ignition temperature preferably lower than the melting point of the first compound (10).

摘要： The invention relates to a mold release agent for producing duroplastic molded parts having a hydrophobic surface. Said mold release agent contains: (i) at least one compound that facilitates a removal of the molded part from the mold, and; (ii) at least one reactive and optionally hydrolyzable silane compound which can chemically react in situ with the duroplastic surface that is formed during the shaping method. The invention also relates to the use of a mold release agent of this type during a shaping method and/or during an aftercuring method in order to produce duroplastic molded parts having a hydrophobic surface, and relates to molded parts produced in this manner.
