Abstract: An ice retaining apparatus for use in a drinking vessel comprises a generally semi-circular surface which defines a plurality of orifices therethrough. The ice retaining apparatus includes retaining clips which are coupled to the semi-circular surface on either end of a diameter of that surface. Preferably, the retaining clips are coupled to the semi-circular surface in a fixed angular relationship defining an obtuse angle in relation thereto. The surface defines a slot therein which, due to the flexible nature of the surface, allows the slot to be widened and narrowed, thereby allowing the geometry of the surface to be varied. Additionally, to accommodate a users nose while drinking, the apparatus may include an aperture along the diameter of the semi-circular surface. The ice retaining apparatus is positioned within a drinking vessel by the retaining clips. The semi-circular surface then acts to block solid objects within a beverage while allowing the liquid to flow freely through.

Abstract: A bone fixation pin includes an elongated pointed shank having an enlarged head at one end thereof. A second shank projects axially from the other end of the head and is joined to a second head which, in turn, is integral with a third shank. An enlarged and relatively long head on the end of the third shank may be gripped by the rotary chuck of a tool for driving the pin. After the pin has been driven into the bone of a digit, the exposed end portion of the pin is detached from the pin by snapping the pin either at the relatively weak second shank or at the relatively weak third shank. A flexible tie for pulling two parallel pins toward one another and placing an osteotomy site in compression may be looped around each pin and captivated axially by the first and second heads.
