    Abstract: The present invention has the scope of protecting the winding against both overtemperature and excessive currents, by using a single device. The invention consists of the idea of constructing a controlled-resistance element acting as a temperature operated fuse to be mounted in contact with the winding, namely a alloy element, designed to melt at a predetermined temperature when, for any reason, this temperature is reached by the stator winding, and designed and constructed in the form of a resistor which also melts when carrying a predetermined current.

    Abstract: The surge protector (24) includes a housing (66) having therein a wire wound resistor (90) and a fuse (100). In order to prevent arcing between the resistor (90) and the fuse (100) under the test positions, the resistor (90) and the fuse (100) are arranged in respective chambers (84, 86) separated by a partition wall (82). Leads (98, 104) to the resistor (90) and the fuse (102), respectively, are glued in position, and the resistor and fuse chambers (84, 86) are free of potting material.

    Abstract: In order to protect in particular electronic circuits from overheating, current or voltage surges, and transients, a fuse is proposed which includes a fuse wire (7) between two connecting wires (8a, 8c), conveniently in the form of resistance wires, on a fuse body (1). The fuse wire (7) is routed over several partitions (5a, 5b, 5c), advantageously three of different heights, and through two openings (6a, 6c) in the central zone (1b) of the fuse body, to connector points (3a, 3c) where it is connected to the resistance wires (8a, 8c). The fuse provides protection simultaneously against voltage and current overloads, transients and thermal overloads, and can readily be incorporated in any circuit since it is about the size of a resistor.

    Abstract: A balancing resistor and thermistor network for telephone circuits, for use in combination with an external relay (12), which reliably handles three levels of adverse conditions, automatically re-sets under certain conditions, is physically small in size, and is strong. It comprises a flat ceramic substrate (25) on both surfaces of which are screen printed thick film balancing resistor films (44). Also screen printed on both surfaces are termination traces (31, 32, 33, 34) having portions (32) so located that when the substrate substantially instantaneously fractures it reliably and substantially instantaneously breaks the circuits through the resistive films (44), the fracture occurring in response to a sudden high voltage overload. Accordingly, there is no damage to, or melting or burning of, small wires in the telephone circuits at points near to or remote from the balancing resistor network. A thermistor film (45) is screen printed directly onto the substrate (25) at a central region (G) where there is no resistive film (44). The thermistor (45) is connected to the relay (12) and its associated circuitry on the telephone line card (circuit board) (11), acting as a sensor to control the relay (12) so that the latter resettably interrupts current flow through the entire circuit board (11) and thus through the balancing resistor network.
