Abstract: The present invention pertains to a temporary stopper for the outlets of toilet bowls. In particular, this stopper is adapted for installation into and removal from the open top of a toilet bowl and when installed is adapted to stop any and all back flow from a connected sewer. Back flow often occurs when a sewer in addition to its normal discharge is also subject to a flow of water such as may be present after a heavy rain. This may be an infrequent occurrence but does occur in toilet bowls in basements and/or first floor installations. Back flow can and does cause damage and odor proliferation in such installations. A temporary plug that is readily and easily installed to halt such back flow prevents damage and afterward cleanup. The need for such a plug is usually for only a short period of time such as 6 or 12 hours although the time period is not a factor in its use.

Abstract: An articulated tube structure to be arranged next to the head of a fiberoptic endoscope to permit same to be tilted in either of four different directions by manipulation of pull wires. The tube structure comprises a series of relatively short elementary tubes each having two pairs of lugs on its opposite ends which are angularly displaced 90.degree. from each other. These elementary tubes are jointed in spaced end-to-end relationship by wire support members passing through their overlapped lugs. The wire support members have holes in their ends located inside the tube structure, and the pull wires extend through the holes with clearance. A recessed inner tube can be nested in each elementary tube to eliminate unevenness of the internal surfaces of the tube structure.

Abstract: A regulatable flush valve for tank type flush toilets includes a piston-cylinder dash pot, a weighted (fluid filled) plug/valve, a cylindrical overflow tube and a fluid vortex generating element secured in a coaxial arrangement vertically above the outlet of the toilet tank. The piston and plug/valve secured to the overflow tube are lifted from a normally closed position by a conventional pivoting handle mechanism. The piston-cylinder dash pot determines the water volume of a particular flush by controlling the rate of descent of the weighted plug/valve. The vortex generating element works in combination with the walls of the raised plug/valve to generate an energetic fluid vortex as the water flows from the tank into the toilet bowl. The vortex generated by the generating element is complementary to vortex generating elements within the toilet basin to increase washing action in the toilet bowl. The above combination of elements significantly reduces the volume of water required for complete flushing action.
