Abstract: A light emitting diode (LED) lighting device that includes a housing and a heat sink assembly received within the housing. The heat sink assembly includes at least a first heat sink member and at least a second heat sink member. A printed circuit board having at least one LED provided thereon is mounted to both the first heat sink member and the second heat sink member. At least one biasing member biases an outer side of the first heat sink member and an outer side of the second heat sink member into contact with an inner side of the housing. Heat from the at least one LED is transferred through the heat sink assembly to the housing, where it is dissipated into the air.

Abstract: A circuit device and a method for providing an interface between a circuit device comprised of a porcelain enameled metal substrate and an external electrical conductor such as a wire or a lead. An aperture is formed in the substrate at the location where the connection is desired. An eyelet is then placed in the aperture. Crimping or other means are used to form a mechanical connection to the substrate and causes the eyelet to be retained in the aperture. The wire or lead of an electronic component is then inserted into the eyelet. The wire or lead is then soldered to the eyelet providing a joint of high mechanical strength.

Abstract: A band heater includes a shoe assembly comprising a plurality of arcuate shoe segments each having a pair of outwardly-projecting extensions and a channel segment formed between the extensions. A strap assembly generally encircles the shoe assembly for retaining same in a circular configuration on an object to be heated. The strap assembly includes opposite side edges which are captured in slots formed by the shoe segment extensions. The strap assembly is thus retained generally within a continuous, annular channel formed by the shoe assembly. The strap assembly side edges can slide longitudinally within the shoe segment extension slots whereby relative movement, for example, due to thermal expansion and contraction, is accommodated. A thermal control unit, such as a tubular electric resistance heater, is located generally within the shoe assembly for conductivity heating same and is generally covered by the strap assembly.

Abstract: An improved cartridge heater comprising a electrical resistance heating wire coil enclosed in a stainless steel cylindrical sheath and having bonded thereto a coating containing a solid lubricant and a binder. The solid lubricant providing for ease of removal of the cartridge heater from a bore hole into which it has been inserted for use and providing a barrier to corrosion between the cartridge heater and the metal of the apparatus in which the bore hole is located.

Abstract: A heater assembly includes a heater with an electrical resistance wire element bonded between first and second layers of silicone rubber insulation. First and second conductor plates each having inner and outer surfaces are clamped together with the heater between their inner surfaces. A resettable, thermostatic switch is mounted on the outer surface of one of the conductor plates and opens when the conductor plate reaches a predetermined temperature.
