    摘要： Electrical plug connectors of the male type, which are adapted to be matingly inserted into a female portion, wherein the male includes spring-biased, captive ball shaped members, preferably made of an insulating material such as a borosilicate glass for urging the male member against the corresponding arcuate contact surface of the female socket to which it is inserted with a relatively even distributed pressure, so that a substantial area of current contacting interface results. The male portion includes two different radii of curvature, at least one forming an arcuate contact surface in cross-section which subtends an arc of less than 180*.

    摘要： An auxiliary or emergency lighting system for use with electric discharge lamps, and more particularly mercury vapor lamps. Means are provided for detecting the loss of energy or illumination in the primary discharge lamps and responding thereto to turn on an emergency lamp. In one embodiment, the emergency lamp may be selectively supplied with electricity from either the primary power source or from a battery, depending upon whether the electrical discharge lamps are momentarily or permanently deprived of energy. The battery for the emergency lamp is charged by a charging circuit connected to the primary power source and operative during normal operation of the electrical discharge lamp. A second embodiment uses a light-detecting device for triggering the emergency lamp into operation and includes means for providing both a fast charge and a trickle charge to the battery, depending upon the charge state of the battery.
