International Classification:

G01G 2318

US Classification:

177 45, 177225, 177245, 600580

Abstract:

A fluid sensor apparatus for monitoring fluid in a container. The fluid sensor apparatus comprises a housing having an upper hook extending from a top thereof to allow the housing to be suspended. A lower hook is telescopically received in the housing and extends from a bottom thereof. The lower hook is adapted for suspending a fluid container therefrom. The lower hook is movable relative to the housing. A cam member is located inside the housing and is movable relative thereto. The cam member is coupled to an upper end of the lower hook. The cam member has a stepped gradation. A biasing member is coupled between a lower shoulder of the cam member and the housing. The biasing member is adapted to apply a force against the cam member to cause the cam member to be biased upward relative to the housing to an upper position. A switch is coupled to the housing and has an actuator located in relation to the stepped gradation of the cam member. The switch is in a first state when the cam member is in the upper position.

Abstract:

For use with dental position indicating devices for dental x-ray machines that are collimated and are of round transverse cross sectional configuration defining a bore for the length of same, with such bore having its internal surfacing lined for x-ray absorption and having an x-ray emitting end, a snap-fit collimator device therefor for use with rectangular dental instrumentation that is in the form of a body providing a collimator of rectangular form in the size of such instrumentation, with the body being arranged for snap-fit mounting of same on the x-ray emitting end of such round type position indicating devices, with the arrangement involved providing for rotational adjustment of said body relative to such position indicating device for permitting the collimator of same to be aligned with rectangular dental instrumentation, when the position indicator device in question is secured to an x-ray machine in the course of practicing dental radiography.
