Abstract: A lighted post includes a stanchion and a light assembly. The light assembly includes a body, with a light emitting surface, and a light source that is coupled to the body. The light assembly is adapted for coupling to a power source for powering the light source. When powered light from the light source is directed into the body and is directed from the body through the light emitting surface. The light assembly is mounted to the stanchion, with the body being located in a light transmitting opening provided in the stanchion, such that the light emitting surface faces outwardly from the stanchion to thereby direct light outwardly from the stanchion.

Abstract: The present invention is a method which relies on pressure pulse cleaning. By "pressure pulse cleaning" it is meant that the pressure and temperature of a fluid, such as carbon dioxide is raised to near or above supercritical conditions, which is then contacted with the item(s) to be cleaned. Periodically, the pressure of the supercritical fluid is pulsed or spiked to higher levels and returned to substantially the original level. Potential candidates for treatment by the present invention include but are not limited to precision parts such as gyroscopes used in missile guidance systems, accelerometers, thermal switches, nuclear valve seals, electromechanical assemblies, polymeric containers, special camera lenses, laser optics components, and porous ceramics.

Abstract: Disclosed is a process for recrystallizing materials that are ordinarily difficult-to-comminute. The process utilizes supercritical fluids and gasses at conditions near their respective vapor pressures which have the ability to dissolve in and expand liquid solutions. The process has been shown to be particularly effective at separating HMX and RDX thereby resulting in a precipitate of RDX which is essentially free of HMX.
