Abstract: An apparatus is disclosed which provides distraction of the talo-tibial joint so as to allow performance of arthroscopic surgery of the ankle. The apparatus is readily connectable to a standard operating table and allows for adjustment of the amount of tension induced to the patient's ankle. The apparatus includes a unique foot engaging device which includes only two straps; a first calcaneus strap and a second dorsum strap. The straps are connected to one another and to the foot and ankle of the patient by use of hook and loop-type material fasteners. The use of such fastening material allows ready adjustment of the straps about the patient's foot and ankle so as to provide proper plantar and dorsiflexion when the cable of the distraction apparatus is attached to the ends of the calcaneus strap.

Abstract: The disclosure embraces relatively movable or adjustable members or elements forming control components of a charge forming apparatus or carburetor wherein one or more members or elements are adjustable or movable relative to a mounting means, the disclosure embracing a method and arrangement wherein substantially spherical bodies or balls of deformable resinous or plastic material associated with the movable members or elements are disposed to establish a substantially constant amount or degree of friction between a mounting means and one or more of the movable or adjustable members or elements to assure retention of the movable members or elements in adjusted positions.
