Abstract: A kit for cleaning clogged conduits and thruhole fitting valves in water intake systems of pleasure boats, fishing boats and yacht marine craft includes a hollow, substantially cylindrical male hose coupler connected to a nipple or elbow joined with the valve, and an open-end cap having a flexible, resilient press-fitted inner gasket configured with a central orifice to receive a shaft of larger diameter able to be force-fitted through the cap, the coupler and the valve when opened, and of a strength sufficient to force-free any matter clogging the input hose to the valve from acceptable performance usage.

Abstract: A flapper cap container closure including a cover-lid having a first flap hinged to the cap and to second and third flaps overlying the apertures of its web, whereby depressing the first flap automatically positions the second and third flaps to depress and seal off the apertures of the closure.

Abstract: A dental mirror stem in which a shaft abuts against, and is contiguous with a side surface of a substantially circular disc provided with a reflective surface in forming the dental mirror stem with only the shaft supporting the disc as the reflective surface for the mirror, thereby eliminating the frame of prior dental mirror stems in which a glass surface was inserted, to eliminate a channel where tooth particle debris, blood, virus and other contaminants are captured and collected during dental drilling.

Abstract: Message identifying information in available microdot and microchip format is applied to a tooth, where it can be easily coated over, yet still readable by appropriate scanning devices. The microdot or microchip can be a passive device, for external reading, or can be active to transmit information to the scanner.
