    Abstract: A fuse has a fuse element (6) with a fusible conductor (7) of a conductor material (8) such as Ag, Cu or Al and is provided with doping points (9) following one another at regular intervals. There, the conductor material (8) has a directly adjoining layer of a first compound (10) of the same with a doping material such as In or Ge. It forms mixed crystals which contain the conductor material (8) and the doping material in a fixed stoichiometric ratio, such as for example Ag2In, and is separated from said conductor material by a stable phase boundary. The doping points (9) weaken the fusible conductor by lowering the melting point to below 250° C., so that arc formation rapidly occurs there when there are short-circuit currents, although its electrical resistance per unit of length is under some circumstances only a few percent greater than in the remaining region. The fusible conductor (7) bears a continuous layer of a burn-up material (12). It has an ignition temperature which is preferably lower than the melting point of the first compound (10).

    Abstract: Striking alarm system comprises: a housing (13); a spring (16) with a moving end arranged in the housing; actuator (17) leading from the housing and interacting with the moving end; a high ohmic resistance wire (12) connected in parallel to a melting wire of a fuse; and a holder receiving a pre-tension of the spring. The holder contains a section of the resistance wire formed as a coil (18). Striking alarm system comprises: a housing (13); a spring (16) with a moving end arranged in the housing; actuator (17) leading from the housing and interacting with the moving end; a high ohmic resistance wire (12) connected in parallel to a melting wire of a fuse; and a holder receiving a pre-tension of the spring. The holder contains a section of the resistance wire formed as a coil (18). The section of the wire is guided around the moving end of the spring forming a pre-tension and is in partial contact with the material of the activator. Independent claims are also included for the following: (1) high voltage fuse with a striking alarm system; and (2) switch-fuse system with a high voltage fuse.

    Abstract: A volume modified epoxy resin casting composition comprises a three-dimensional cross-linked polysiloxane in dispersed form having a particle size of 0.02-50 mu m that may react with the epoxy resin and/or the curing agent and a linear or branched siloxane compound having reactive groups that may react with the epoxy resin and/or hardener. A volume modified casting composition (I) based on a curable epoxy resin comprising an epoxy resin, curing agent, optionally an accelerator and other additives such as filler, flexibilizing agents and coloring agents is characterized in that the composition (I) comprises (A) a three-dimensional cross-linked polysiloxane in dispersed form having a particle size of 0.02-50 mu m that may react with the epoxy resin and/or the curing agent, (B) a linear or branched siloxane compound having reactive groups that may react with the epoxy resin and/or hardener and optionally (C) a low mol. wt. oligomeric siloxane compound. An Independent claim is included for a process for the production of the composition (I) such that at least a portion of the epoxy group containing components (A) and (B) are pre-mixed and pre-hardened or at least a portion of the hydroxyl, amine or carboxyl containing components (A) and (B) are pre-mixed with the epoxy resin and pre-hardened.

    Abstract: The invention relates to a volume-modified casting compound based on a curab le epoxide resin or a mixture of such resins, comprising an epoxide resin, a curing agent, optionally an accelerator and further additives such as filler s, 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 .mu.m to 50 .mu.m which optionally carries reactive groups capable of chemically reacting with the epoxide resi n 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, an d to the shaped parts and insulations produced therefrom.
