Abstract: The trap includes a container with a top opening covered by a lid. Inlet and outflow pipes extend through the lid into the container. A sheet of mesh filtration material (fiberglass, foam etc.) is situated within the container, below and preferably bonded to the interior surface of the lid. The inlet and outflow pipes extend through the filtration sheet into the container such that as the water level rises, sediment from the water flowing through the container settles to the bottom of the container and floating particles on the surface of the water which would otherwise be carried out of the trap with the water as the water exits the container remain in the filtration sheet.

Abstract: The air compressor has an air intake, a tank, means for pressurizing the air in the tank and an air outlet connected to the tank. High power UV LED light sources are mounted within the tank to disinfect the interior tank surface. The UV LED light sources preferably have an output wavelength within the range of 250 nm to 365 nm, most preferably within the range of 260 nm to 270 nm. Preferably, the light output of the light sources is pulsed. The light source has a cover for protecting the light source which may take the form of a quartz diverging lens. Air flow is directed through the area proximate the light source to remove particles from the light source cover. The effect of this air flow can be amplified by creating turbulence proximate the light sources utilizing a member with an arcuate profile.

Abstract: A borehole is drilled from the surface to an underground shale matrix. A pipe is inserted into the borehole. Openings are created in the pipe in fluid communication with fractures in the shale matrix. The interior surface of at least one section of pipe is coated with a contaminant-capturing substance. Fracturing fluid including water, proppants and chemicals is pumped through the pipe and into the fractures in the shale matrix. The fluid re-enters the pipe from the shale matrix and moves toward the surface through the coated pipe section where contaminants are sequestered by the coating. Natural gas or oil from the fractured shale then enters the pipe and moves to the surface to be collected. The coated pipe section remains in the ground permanently such that the necessity of disposing of the captured contaminants is eliminated.

Abstract: A sanitary catchall trap utilizing an aqueous dispersion medium for improved antibacterial and deodorant capabilities in the capture and disposal of waste. The trap includes an interior and a lid for enclosing the interior. The trap includes an odor controlling substance dissolvable in the aqueous dispersion medium, a cage having a receiving portion for housing the odor controlling substance, and a fastening portion for mounting the cage to the interior of the trap. A biodegradable, water-soluble barrier encloses at least a portion of the receiving portion of the cage for shielding the substance from leakage prior to use.

Abstract: The dental model trimmer includes a wheel having an abrasive surface, a motor for rotating the wheel, and ultraviolet light source powerful enough to inactivate bacteria. The components are located in an enclosure that has an opening to permit access to the abrasive surface of the wheel. The light source is mounted within the enclosure to illuminate a section of the abrasive surface of the wheel that is spaced from the access opening. The enclosure includes wall means interposed between the light source and the access opening for preventing direct light emitted from the UV light source from exiting the access opening. The enclosure is provided with an interlock switch that will automatically turn off the light source when the enclosure is opened. The same switch can be used to deactivate the motor and a source of water provided to the abrasive surface, if desired.

Abstract: A plastic material sheet for use in vacuum thermoforming is formed of polymer material. Electrically conductive resistance elements, at least a portion of which are situated within sheet, conduct electrical current to heat the sheet. The elements are generally parallel to each other. They may be straight, have a generally zigzag configuration, a generally serpentine configuration, an arcuate configuration, or a grid-like configuration. The elements may each have a section that extends substantially beyond the edge of the sheet. They may be frangible. They may be embedded deeply within the sheet or may be situated proximate a surface of the sheet.
