Abstract: The magnetic elements of a reed switch are supported within their non-magnetic capsule so that, instead of coming into contact in initially overlapping relationship, under the influence of a magnetic field they become essentially aligned with one another. The reeds may be so constructed that by selection of the size or shape of their respective opposed ends, the magnetic flux pattern is modified to maintain desired relative alignment to achieve desired contact. The invention relates to a mercury wetted switch which employs mercury to complete electrical contact between the non-contacting ends of the reeds.

Abstract: This disclosure is related to electrical generators which utilize heating and cooling of separate points in a closed circuit ferrofluid system to generate electrical power directly from heat energy. The characteristic of ferrofluids to experience rapid change in their magnetic properties with temperature is utilized by placing a magnet around the circuit to create a self-pumping action of the ferrofluid through a solenoid to generate electric power.
