A ratchet for use with a cord includes a pair of opposed tear drop shaped members defining a one piece housing for rotatably supporting a one piece ratchet spool, for supporting a pivotally mounted thumb release and for supporting an angularly displacable hook. Opposed circular cavities are disposed within the members to rotatably support corresponding bosses extending from opposed sides of the spool. A plurality of opposed interleaved non-radial ribs extend from opposed surfaces of the spool to frictionally grip a cord partially extending about the spool. A pair of wheels forming the spool are interlocked with and secured to one another through a key and keyway.

A method and composition for preventing and treating all forms of osteonecrosis of the jaw are disclosed. The composition is comprised of 0.005%-2.0% weight/volume (w/v) chlorine dioxide source, such as sodium chlorite, chlorite ion, stabilized chlorine dioxide or similar and may take the form of a paste, gel, rinse, spray, powder, varnish or similar. The method for treatment and prevention includes the application of the composition in the oral cavity and other body areas affected by osteonecrosis of the jaw.

A prover mounted upon a supporting lower framework includes a piston supporting rod extending longitudinally through a cylinder. Motive means supported on a frame mounted on the prover draws the rod toward the fluid receiving end of the cylinder. An upper framework is attached to the lower framework through a plurality of stanchions. Various I-beams formed as part of the upper framework enhance rigidity to the combination of lower framework and upper framework. The combination of lower framework and upper framework provides support for the prover in a horizontal or a vertical orientation without affecting the operation, repair or maintenance of the prover.

Mandrel supported IV tubing is inserted within a mold of a mold assembly to heat the IV tubing and form a tapered end of the tubing. The tip of the tubing extending beyond the tapered end of the tubing is severed by the mandrel bearing against the mold to lodge the tip in an outlet of the mold. Cooling air is introduced to the mold assembly to cool the mold and to create a flow of turbulent air about the outlet of the mold to extract the severed tips. The turbulent air is exhausted through a channel, pipe and fitting into a collection chamber and causes translation of the severed tip to and into the collection chamber. Sensors may be incorporated to sense the translation of the severed tips.

A receiver extends from the top of a retractable wheel assembly to receive the lower end of a jackstand or the like. Upon exerting pressure on a foot operated plate, a wheel is extended from the bottom of a plate and locked in place with a catch to permit transport of a trailer or the like attached to the jackstand. Upon release of the catch, the wheel will retract to bring the plate into contact with the ground and immobilize the trailer.

A method for determining the available treatment dosage of stabilized chlorine dioxide in the prevention and the treatment of plaque accumulation, volatile sulfur compound production, gingivitis and periodontitis, and for differentiating the treatment dosage from other chlorine-containing compounds that may not have such beneficial effects is disclosed. When in solution as stabilized chlorine dioxide, the presence of other ions such as chlorate and chloride may not only obscure results as to the concentration of stabilized ClO2, but also reduce the predicted effectiveness. The present invention uses validated analytical methods to predict the effectiveness of stabilized ClO2 by more precisely measuring its concentration in solution. Such measurement renders precision at a level required of food-grade and pharmacy-grade chemotherapeutic agents in the oral cavity. Preferred concentrations are within the range of about 0.005 to about 2% (w/v) stabilized chlorine dioxide. The solution may be in the form of wash, rinse, soak, paste, gel, aerosol spray, or other suitable delivery system.

A mold for forming, molding or welding thermoplastic tubing extends through the aperture of an apertured spool supporting an RF energized coil to inductively heat a center section of the mold. A source of air is channeled through a manifold to flow about the center section of the mold and through the space between the mold and the aperture in the spool to rapidly cool the mold. Thermal chokes on each side of the center section of the mold impede heat transfer and a heat sink connected to each thermal choke serves to dissipate any heat build up. The spool may be translated along the center section of the mold to a predetermined location commensurate with a predetermined heat profile. The mold includes a passageway extending therethrough for receiving the tubing; by appropriate dimensioning, the passageway will accommodate the use of a mandrel to support the tubing to be formed, molded or welded. The mold may be split to permit separation within the confines of the aperture in the spool and subsequent withdrawal of the formed, molded or welded tubing.
