摘要:
The device 10 includes a liquid filled bellows activated battery composed of two non Miscible fluids 14, 15 flowing through a channel 13 containing two electrodes 16, 17 of different metals. One of the fluids 14 is an electrolyte while the second 15 one is electrically non conducting. At rest the two electrodes 16, 17 are in the non conductive fluid 15. When the electrical device is actuated, manually or by an external force, the fluids surrounding the electrodes 16, 17 are replaced by the electrolyte 14 thus generating an electrical voltage between the two electrodes. The electrical current can be used to temporarily generate light or supply energy to another device. When the actuation mechanism is released, the electrodes 16, 17 are surrounded by the non conductive fluids 15 again and the electrical current is stopped.
摘要:
A mercury switch having a nonconductive housing within which is mounted a pair of spaced apart electrodes and a quantity of mercury in an amount sufficient to bridge the space between the electrodes depending on the position or movement of the switch. Also included in the housing is a filler of liquid ether, preferably butyl Cellosolve (ethylene glycol monobutyl ether), having a freezing point lower than that of mercury and a boiling point at least as high as 100* C., the liquid filler having a viscosity which changes little, if any, between the freezing temperature of mercury and 100* C.

An apparatus for toggling circuits includes a plurality of parallel channels each having a first end and a second end, a plurality of ports transverse to the plurality of parallel channels, wherein each port has a plurality of valves corresponding to the plurality of parallel channels, wherein each valve selectively opens and closes in response to an input and wherein opening a valve fills a portion of a port with a conducting fluid. The apparatus also includes a controller communicatively coupled to the input of each valve and configured to complete an electric circuit between the first end of the parallel channel and the port corresponding to the valve when the controller opens the valve. A method executed by a computer and a corresponding computer program product are also disclosed herein.
摘要:
A fluid-sensing switch system that can monitor pre-established threshold fluid levels in the primary drain pan inside an air conditioning unit or other condensate-producing unit, and also in a secondary drain pan positioned under the unit. Once the threaded plug of a sensing probe is connected to the unit's weep hole, it positions a center sensor providing a first power potential through a false-trigger-reducing resilient piece in a position to wait for rising fluid capable of breaching a weep hole dam. A substantially circular sensor is also present provides the second power potential needed for signal generation. A signal-generating member connected to both sensors is electrically connected to the unit to shut it off, and/or activate a pump that removes fluid from the secondary drain pan. The signal-generating member provides the redundant safety alarm capability, when mounted on a secondary drain pan. Anti-microbial elements are optional, but preferred.
