  • Publication number: 20190244778
    Abstract: A circuit breaker or conductor severing assembly can include a housing with a conductor extending through the housing. A piston disposed within the interior of the housing can be actuable within the housing between a first position and a second position, driven by a volume expansion composition. The piston can include a cutter, such that actuation to the second position can sever the conductor extending through the housing.

  • Patent number: 8551263
    Abstract: A method of reducing whisker growths includes identifying a solder connection to be treated. The solder connection may contain one or more whisker growths. A heat source is applied at a defined temperature to the solder connection for a defined period of time sufficient to melt at least a portion of the one or more whisker growths. The heat source is removed from the solder connection prior to the melting of the solder connection.

  • Publication number: 20120111190
    Abstract: A closed loop air handling system for monitoring and cleaning air from corrosive contaminants. Commonly occurring corrosive elements found in air can react in combination together and with other environmental conditions to increase the propensity for corrosion to occur. The higher corrosive level of air can react with metals causing degradation, wear and often lead to premature failure. This is especially prevalent in environments using forced air convection for cooling, such as data centers. The electronic circuitry is especially vulnerable to such corrosion and requires an environmentally controlled atmosphere with mild corrosiveness for long term reliability. The invention involves circulating the air in a closed loop and monitors and adjusts parameters of active filtration and purification to minimize corrosive agents. The system maintains a milder corrosive environment and better accommodates the use of “free cooling” from outside air for improved energy efficiency and lower carbon emissions.
