Abstract: A method of producing an electrode by applying onto a core material a solution of at least one metal salt and subjecting the resultant core material to a heat treatment in a heating zone, characterized in that said heat treatment comprises continuously elevating the temperature of the resultant core material to a temperature of about 400.degree. to 700.degree. C. over a period of about 5 minutes to 2 hours, while blowing air into the heating zone to obtain a coated electrode. The coated electrode produced according to the method of the present invention is excellent in adherence of the coating to the core material and has long life due to low losses of the coating during use.

Abstract: A temperature responsive current interrupter in which two conductors are connected by electrically conductive, low-melting-point fusible elements respectively mounted on the conductors and a connector element interconnecting the fusible elements and urged against an electrically non-conductive high-melting-point fusible element, the connector element being moved into a position separate from at least one of the conductors when the high-melting-point fusible element is melted by heat.
