Abstract: The present invention is a gun barrel light to illuminate an interior of a barrel of a gun that includes an acrylic solid rod with a distal end and a proximal end wherein the distal end is curved at an approximate 45 degree angle, the distal end of the solid rod is inserted into the interior of the barrel of a firearm to illuminate the interior of the barrel and an external light source that emits and directs light that illuminates the interior of the barrel of the firearm. The gun barrel light has two embodiments and widths and can accommodate a .22 caliber handgun or a .45 caliber rifle.

Abstract: An apparatus for sterilizing various articles includes a chamber defining an airtight space and an entrance and exit. A vacuum pump is coupled to the chamber for withdrawing air therefrom which reduces the chamber air pressure. An ozone generator is coupled to the chamber for introducing ozone at atmospheric pressure therein following air withdrawal. This causes efficient diffusing of the ozone into the article for sterilizing it against anthrax. The ozone is then withdrawn into an ozone filter having a non-consumable catalyst for converting the ozone back into oxygen. The apparatus may be implemented using single or multiple chambers. A conveyor extending through water chambers surrounding respective sterilizing chambers may be utilized for conveying textile articles while more traditional conveyors may be utilized for traditional mail articles.

Abstract: This invention provides a framework for simplified and rigorous methods and means for the determination of the squareness error between two orthogonally driven carriages of a machine. The method uses the principle of a geometric kite in which the lines formed between opposing vertices are inherently orthogonal. By utilizing a partial kite-shaped structure having three measurable datums associated with three of the vertices of a geometric kite and by rotating the structure about the line of rotation formed by two of the three datums, the positions of the third vertex will form a circle that has the property the plane in which it lies is orthogonal to the original line. Additionally, any two points located on the circle will form a line that is orthogonal to the line of rotation. The structure is measured in multiple orientations attached to the table of a machine.

Abstract: A lateral expandable interbody fusion cage expands laterally between two vertebrae to promote fusion between the two vertebrae. The cage includes an outer cage and at least one inner cage, with optional flanges and spikes.

Abstract: A tubing clamp for firmly retaining flexible tubing without occluding flow through it and for forcing the tube into straight and open configuration. The tubing clamp rests on a platform member and comprises a pair of jaws positioned in opposed relation to each other and pivotally mounted on the platform member to be pivotally movable between open and closed positions. Facing surfaces of the jaws defines recesses that together define a tube port in the closed position of substantially the outer diameter of the tubing intended for retention therein. The tube has a parting line, and the jaws also define overlapping members at the parting line to prevent pinching of tubing occupying the tube port in the parting line as the jaws are moved to closed position.
