Abstract: A device and method for elimination of contamination during transfer of materials either into or from bioreactors, food containers, or other microbially vulnerable systems. Using microwave power, thermal sterilizations of mating fixtures are achieved simply, reliably, and quickly by the volatilization of small quantities of water to produce superheated steam which contacts all exposed surfaces.

Abstract: A "reagentless" chemiluminescent biosensor and method for the determination of hydrogen peroxide, ethanol and D-glucose in water. An aqueous stream is basified by passing it through a solid phase base bed. Luminol is then dissolved in the basified effluent at a controlled rate. Oxidation of the luminol is catalyzed by the target chemical to produce emitted light. The intensity of the emitted light is detected as a measure of the target chemical concentration in the aqueous stream. The emitted light can be transmitted by a fiber optic bundle to a remote location from the aqueous stream for a remote reading of the target chemical concentration.

Abstract: Low cost and portable safety side shields for safety eye glasses which substantially protect eyes from harm caused by projectiles impacting the eye through open areas between the wearer's head and the eye glass frames. The side shields have no conducting parts, are resistant to impact, shattering, and chemical corrosion, and are securely fastened to the ear pieces of the eye glasses by a stretchable tube. The side shields fit inside of the ear pieces without touching the eye glass wearers face, and overlap portions of the top, side and front of the lens frames to prevent latitudinal, longitudinal and rotational slippage that would expose the eyes. An alternative embodiment provides further eye protection by partially overlapping the front of the lens frames in the area of the eye glass hinges.
