    摘要： The invention provides polymeric PTC compositions and electrical PTC devices that have a high voltage capability and are capable of operating at alternating current (AC) voltages of 110 to 130 volts or greater, such as those present in household AC electrical lines. The polymeric compositions demonstrate a high PTC effect of at least 10 4 to 10 5 and a low initial resistivity at 25°C of 100 Ωcm or less, preferably 10 Ωcm or less, resulting in electrical PTC devices having a resistance at 25°C of 500 mΩ or less, preferably about 7.5 mΩ to about 200 mΩ, typically about 10 mΩ to 100 mΩ. The devices of the invention can withstand a voltage of 110 to 130 VAC or greater without failure for at least 4 hours, preferably up to 24 hours or more, after reaching the switching temperature.

    摘要： A power terminal feed-through includes a housing body, a plurality of conductive pins, and a seal structure that hermetically seals the conductive pins to the housing body and electrically insulates the conductive pins from the housing body. The seal structure includes a first material fused to one of the housing body and the conductive pin, and a second material fused to the other one of the housing body and the conductive pin. The first and second materials may be properly chosen to match thermal expansion of the housing body and the conductive pins, respectively.

    摘要： A humidity-modulated dual-setpoint temperature controller is disclosed in which the two setpoints of the temperature controller are adjusted as a function of measured humidity. Parameters other than humidity could also be used to adjust the dual setpoints of the temperature controller. The controller is particularly useful in controlling the heater element of a clothes dryer in order to improve the energy efficiency of the dryer.
