Use of serospecific biocarrier compositions for enhanced biodegradation and bioremediation of groundwater

Description: A composition and method for using the composition for degrading pollutants in-situ is presented. The composition comprises a biocarrier coated with an antigen-specific antibody that attracts and binds pollution-degrading antigens. The biocarrier, which is preferably in the form of glass microspheres, is coated with one or more strains of antibody. The antibody may be placed into the ground in or near the source of pollutants where it may attract antigens present and bind them, or the antibodie… more

Starting apparatus for internal combustion engines

Description: This report is a patent description for a system to start an internal combustion engine. Remote starting and starting by hearing impaired persons are addressed. The system monitors the amount of current being drawn by the starter motor to determine when the engine is started. When the engine is started the system automatically deactivates the starter motor. Five figures are included.

Closed-field capacitive liquid level sensor

Description: A liquid level sensor based on a closed field circuit comprises a ring oscillator using a symmetrical array of plate units that creates a displacement current. The displacement current varies as a function of the proximity of a liquid to the plate units. The ring oscillator circuit produces an output signal with a frequency inversely proportional to the presence of a liquid. A continuous liquid level sensing device and a two point sensing device are both proposed sensing arrangements. A second … more

Optical temperature indicator using thermochromic semiconductors

Description: A reversible optical temperature indicator utilizes thermochromic semiconductors which vary in color in response to various temperature levels. The thermochromic material is enclosed in an enamel which provides protection and prevents breakdown at higher temperatures. Cadmium sulfide is the preferred semiconductor material. The indicator may be utilized as a sign or in a striped arrangement to clearly provide a warning to a user. The various color responses provide multiple levels of alarm.

Hydraulic pump with in-ground filtration and monitoring capability

Description: A hydraulically operated pump is described for in-ground filtering and monitoring of wells or other fluid sources, including a hollow cylindrical pump housing with an inlet and an outlet, filtering devices positioned in the inlet and the outlet, a piston that fits slidably within the pump housing, and an optical cell in fluid communication with the pump housing. A conduit within the piston allows fluid communication between the exterior and one end of the piston. A pair of O-rings form a seal b… more

Vitrification of organics-containing wastes

Description: A process for stabilizing organics-containing waste materials and recovery metals therefrom, and a waste glass product made according to the process are described. Vitrification of wastes such as organic ion exchange resins, electronic components and the like can be accomplished by mixing at least one transition metal oxide with the wastes, and, if needed, glass formers to compensate for a shortage of silicates or other glass formers in the wastes. The transition metal oxide increases the rate … more
