The integrally connected non-metallic jaw assembly and the single flat support are centered within the tubular member through the threaded self-centering proximal end.

Abstract: A directed graph is logically zoomed, whereby the appearance of a node directly related to a target node can be exaggerated and the structure of an entire graph can be readily understood. A directed graph is used in which hierarchical nodes are connected by arcs. In the directed graph, a node that has a predetermined logical relationship with a selected node is displayed differently than are the other nodes. For example, a displayed node logically near the selected node is large, while a displayed node logically distant is small, or the node logically near the selected node is moved closer to the selected node.

Abstract: A panel, paneling system and method of installing the paneling system. The panel includes a tongue and groove for engaging adjacent panels, a profile having cross members for reinforcement and the ability to attach the panel or paneling system to a wall.

Abstract: A table game provides for realistic simulation of known athletes' performance in the context of a virtual game predicated upon the career statistics of those athletes, uses card carrying along one of their edges, space-proportioned zones representing the percentage of occurrence of each possible outcome of a player's move during that player's career. A random number generator drives a display of a series of individually selectable points or locations that are matched to one of the zones in order to determine the outcome of a virtual move. The game is particularly adapted to the simulation of baseball, cricket, basketball, or golf competitions.

Abstract: A device for preparing and injecting a polymeric bone cement under sterile, isobaric and isovolumic conditions includes a cylindrical vessel holding a volume of polymeric powder and a disk agitator mounted on a shaft passing through an aperture in a proximal end wall of the vessel and extending beyond the agitator though a delivery port in an opposite wall of the vessel. A piston can be selectively coupled to the disk in order to inject the contents of the vessel through the outlet port. The device can be packaged in a sterilized, evacuated envelope. The cement is ejected by breaking off a distal, tubular section of the shaft and mounting the broken off section over an external bushing surrounding the outlet port and moving the piston toward the outlet port to expel the contents of vessel.

Abstract: Improved compositions for treating psoriasis, including a body wash composition, spray composition and cream composition and the use of these novel compositions in a system or method of treating psoriasis.

Abstract: The invention comprises a belt installation tool for installing a flexible belt on a pulley. On one side, the radius of the tool is substantially equivalent to the radius of a pulley flange. The bearing surface on this side of the tool stretches the belt and guides the belt onto the pulley. To avoid damaging the belt, the radius of the tool and the pulley flange should be substantially equal over a substantial length of the pulley. Centric to this radius, a hole is provided to accommodate a single-end socket that projects through the tool. The socket engages a crankshaft bolt, hence, the belt installation tool is centered on the pulley along the socket centerline. The tool and pulley are then turned with a ratchet attached to the socket. The tool comprises a belt bearing surface having a variable radius that allows a belt to be stretched to a proper radius without abrupt radius changes, which could damage a belt.

Abstract: The system includes an access assembly for communicating with the gas filled insulating units, flexible electrodes for insertion through the access assembly to the gas and for sensing the concentration of the gas, and a meter for measuring and displaying the concentration of the gas that is sensed through the electrodes.
