    • A refractory hanger brick for high temperature industrial furnace roof construction having an elongated upwardly extending refractory portion having a generally rectangular cross section and a lower refractory base portion having a generally rectangular lower face, each side of the base portion having a base length greater than a corresponding side of the elongated upwardly extending refractory portion so as to provide support for insulating material and/or adjacent filler bricks. The upper end of the elongated upwardly extending refractory portion distal from the lower refractory base portion forms a hanger recess along opposite sides of the upper end. At least one generally laterally extending lug is disposed above each of the hanger recesses to retain the hanger in a fixed position and to provide at least one hanger position along the upper end opposite sides.

    • An apparatus and method for temperature-dependent transient blocking employing a transient blocking unit (TBU) that uses at least one depletion mode n-channel device interconnected with at least one depletion mode p-channel device. The interconnection is performed such that a transient alters a bias voltage Vp of the p-channel device and a bias voltage Vn of the n-channel device in concert to effectuate their mutual switch off to block the transient. The apparatus has a temperature control unit that is in communication with the TBU and adjusts at least one of the bias voltages Vp, Vn in response to a sensed temperature Ts, thereby enabling the apparatus to also respond to over-temperature. In some embodiments the p-channel device is replaced with a positive temperature coefficient thermistor (PTC). The temperature control unit can use any suitable circuit element, including, among other a PTC, resistor, negative temperature coefficient element, positive temperature coefficient element, transistor, diode.
    • 一种采用使用与至少一个耗尽型p沟道器件互连的至少一个耗尽型n沟道器件的瞬态阻塞单元(TBU)的温度依赖性瞬态阻塞的装置和方法。 执行互连,使得瞬态改变p沟道器件的偏置电压V SUB p N和N沟道器件的偏置电压V N n N一致地实现 他们的相互关闭来阻止瞬态。 该装置具有与TBU通信的温度控制单元,并响应于感测到的温度T 1调整至少一个偏置电压V SUB,V SUB, 从而使得设备也能够响应过温。 在一些实施例中,用正温度系数热敏电阻(PTC)代替p沟道器件。 温度控制单元可以使用任何合适的电路元件,包括PTC,电阻器,负温度系数元件,正温度系数元件,晶体管,二极管等。
