Abstract: An assembly is disclosed featuring a utility service pole bottomed on a floor of a room, a pole hanger fixed to a ceiling suspension member and a connector therebetween which not only serves to cooperate with the hanger to maintain the service pole in an upright position but additionally supports the hanger for movement relative to the service pole to automatically compensate for relative movement of the ceiling suspension member and the floor toward and away from each other without lifting or otherwise distorting the service pole.

Abstract: A substrate of photoconductive semiconductor material is anodized by electrolysis in an electrolyte such as, for example, 0.1M KOH 90% ethylene glycol - 10% deionized water to form anodic oxide surfaces to stabilize the surface state density to prevent recombination hole-electron pairs during sweepout thereby producing a long term, high temperature stable infrared detector.

Abstract: The depressed dome portion of the cap is scored part way through the thickness of the material thereof and immediately adjacent the inner periphery of the overlying ring portion. The score forms a continuous line extending nearly completely around the dome portion but interrupted for a short distance to provide an unscored hinge portion. The depth of the score is sufficient to allow downward finger pressure on the dome portion to break the material thereof along the score line and permit the dome portion of the cap to be bent downwardly about the hinge portion and into the neck of the bottle to which the cap is attached.
