Abstract:

A disposable protective sleeve for temporarily covering a hand-held dental light curing gun having an elongated handle portion and a barrel portion that tapers to a transmitting end having a light guide from which light emanates, the gun having a curved transitional portion between the handle portion and the barrel portion. The disposable protective sleeve is made from a flexible plastic elongated tubular body with an opening at one or both ends. The body defines a generally straight proximal section and a curved section. The larger end opening is larger than the transmitting end, the barrel portion, the transitional portion and the handle portion of the curing gun, so that the sleeve is adapted to be placed over at least most of the curing gun by passing the larger end opening over the transmitting end, barrel portion, transitional portion and handle portion of the curing gun, so that the sleeve covers at least the transitional portion and at least most of the handle portion of the gun.

Abstract:

A dressing unit for advancing and retracting a spindle, having a diamond roll rotatably mounted thereon, wherein advancement of the spindle brings the diamond roll into contact with a grinding wheel for dressing the grinding wheel. The dressing unit comprises an outer ram mounted within a housing, an inner ram telescopically disposed within the outer ram, means for advancing and retracting the outer ram to a positive stop, and means independent of the advancing and retracting means for incrementally moving the inner ram from an inner position to an extended position. The inner ram is connected to the spindle to advance the spindle to thereby bring the mounted diamond wheel into contact with the grinding wheel.
