Electricity: electrothermally or thermally actuated switches inventions 05/06

20060109073 - Circuit breaker: The invention relates to a re-settable, single-phase, thermo/electric circuit breaker utilizing a U-shape bimetallic element of substantial resistance properties in the circuit, so that when a predetermined overload current occurs the bimetallic element self heats and moves to trip a mechanism that opens the breaker circuit. The invention replaces the...

20060109074 - Resetable over-current and/or over-temperature protection system: An electrical protection system, which can be connected between an electrical power supply and an electrical load, firstly includes a switch switchable between a normal state in which the switch is electrically connected in series between the power supply and the load such that an operating current passes through the...

20060109075 - Doubly-anchored thermal actuator having varying flexural rigidity: A doubly-anchored thermal actuator for a micro-electromechanical device such as a liquid drop emitter or a fluid control microvalve is disclosed. The thermal actuator is comprised of a base element formed with a depression having opposing anchor. A deformable element, attached to the base element at the opposing anchor edges,...

20060097839 - Alloy type thermal fuse and material for a thermal fuse element: An alloy type thermal fuse is provided in which a Bi—Sn alloy is used as a fuse element, which has an operating temperature of about 140° C., which, even when used at a high power, can safely operate, and in which dispersion of the operating temperature can be sufficiently reduced....
