摘要： A syringe shielding apparatus comprising an adapter having a tubular collar and a flexible snap ring joined by a living hinge, and a needle shield. Radially extending projections, provided on the tubular collar, slide within longitudinally extending slots in the needle shield, allowing the longitudinal extension and retraction of the needle shield relative to the housing of the syringe. The flexible snap ring expands into a groove in the needle shield at extension. Expansion of the snap ring into the groove in the needle shield locks the shield in the extended position over the syringe needle.

摘要： A liquid dielectric capacitor is provided housed in a sealed casing having a noncircular cross-section. The casing includes a sealed top cover to which terminals are affixed. An elongated flexible plate member is positioned within the casing spanning a major diameter of the casing. The ends of the plate member substantially abut the interior walls of the casing along the major diameter. Breakable, electrical conductors are affixed to the terminals and plate member. The plate member is preconditioned to bow downwardly, away from the casing top, when the ends of the plate member are subjected to inwardly directed forces, as when a pressure buildup occurs within the casing. The conductors are adapted to break when the relative distance between the terminal and plate exceeds a preselected value.
