Abstract: A valve controls the flow of an inflation substance such as carbon dioxide from a pressurized container when the valve is actuated. The valve comprises a valve body having an inflow bore, inlet conduit, chamber, interior chamber and interior passage connected to each other and with the pressurized container. The valve is connected to an inflatable apparatus such as an emergency slide or raft by an outlet conduit connected to the valve body and with the interior passage. The valve is closed by a piston assembly which is balanced. The piston assembly includes a guidance collar and a first piston rod connected to the guidance collar. The first piston rod has an O-ring seal, and the piston rod is attached to the valve body by a fitting. The second end of the piston rod extends through the piston fitting and has a valve actuation receiving means.

Abstract: A tool for assisting in producing a straight edge on a piece of rough cut raw material, such as lumber or masonite. The tool is held in place on top of the piece by gripping means which grip the piece along two opposite side edges. The tool's straight edge, unobstructed by clamps or other protrusions, is then used as a guide to bank against the saw fence of a table saw, radial arm saw, or circular saw, producing a straight edge on the piece. Using the tool, one can take the flat bow out of a piece and also remove the rough mill edge. The tool can also be used with a hand circular saw, jig saw, or router by running the saw directly along the tool's unobstructed straight edge.

Abstract: A disposable dental floss pick comprising a length of floss filament bonded to a plastic handle.

Also, a method of rapidly and economically producing a dental floss pick utilizing continuous or progressive steelrule die cutting is described.

Abstract: A crushing machine for insertion into a pipeline comprising a generally "T" pipe section containing a crushing cartridge - a plurality of crushing blades rotating within openings of a stationary bar/grid placed perpendicular to the flow in the pipeline. The crushing cartridge is completely removable as an single integral unit for quick and easy repair and reinstallation. A spare cartridge, fully adjusted and ready to use, may be installed while the removed cartridge is being serviced. The "T" pipe section may also be capped when the crushing mechanism is removed so that the pipeline flow may continue.

Abstract: A vehicle location aid for use with a parking lot divided into areas comprising a disposable card containing unique designations for each parking lot area.
