Abstract:

A lighting fixture in the form of a chandelier having chandelier arms. There is a central body having an upstanding fixture part, and to which the chandelier arms are secured. The arms are unique in that they consist of metal tubes of ornamental shape for carrying the wiring and carrying ornamental designs of plastic molded onto the tubes. Within the central body is a metal box to which the tubes of the arms connect and to which also connect vertical tubes for wiring to provide safety. The central body is of molded construction with the metal box within it.

Abstract:

A frame body has a base portion for supporting a specimen and an integrally extending arm portion above the base portion for guiding a penetrating probe. Force is applied to the probe to urge it against the specimen. A portion of the frame body is in the form of a leg extending horizontally in spaced relationship to the base portion of the frame to terminate adjacent to the specimen. Reaction of the frame to applied forces causes relative movement between the base portion and the horizontally extending leg indicative of "springing" of the frame. A first electrical circuit provides a first signal proportional to the load applied to the penetrating probe. A second electrical circuit provides a second signal responsive to relative movement of the penetrating probe and supporting arm and a third electrical circuit provides a third signal responsive to relative movement between the base portion of the frame and the extending leg. A further circuit receives the second and third signals and subtracts the third signal from the second signal to provide an output signal which accurately indicates the penetration of the penetrating probe into the specimen. Any "springing" movement of the frame as a consequence of loading which would introduce an error into the depth of penetration measurement is thus automatically compensated.
