Abstract: A device which will allow removal of water from the pipes and associate equipment servicing a swimming pool without partially draining the pool consisting of a first member equipped with means for water-tight engagement with an outlet in the sidewall of a pool structure and a second member equipped with a standpipe. When the first and second members are tightened into water-tight relationship, a vent is provided from the outlet in the sidewall of the pool to the outside air. The water in the pipe associated with the outlet can then be removed without the necessity of draining any water from the pool.
Abstract: A disposable urinating funnel for females comprises a thin, paper-like sheet which is folded in half to form two overlapping sections whose free edges are connected together and are tapered toward the fold line to form a funnel-like shape. The upper edges of the funnel-shape are curved to cover a female vaginal area, and the opposite, bottom edges form a spout-like portion. Score lines are formed midway between the fold line and connected side edges in each of the sections and extend upwardly from the bottom of the spout-forming portion toward the upper end of the funnel-like shape. Manually squeezing the fold line and connected side edges toward each other causes the otherwise flat funnel-like shape to open, by bowing the sections apart along the score lines. In addition, the tapered, connected-together edges are cut along a shallow curve which permits the funnel to be used with the fold line forwardly or rearwardly for selectively directing the flow of liquid through it.

Abstract: A new type of stool cover had an air tight and hollow inside part of its seat-ring, with bottom that is fitted with drafting openings with fittings to plug up the openings. A plug system involves a support, a spring, a plug support, and a filler associated with each draft opening in the bottom of the seat-ring. The plug support and the filler are made of one piece. While the user is sitting on the seat-ring, the plug support moves upward against the spring, in turn moving the filler away from the drafting opening. The drafting openings are then just opened, and draft from their location on top of the stool. The bad smell produced in the stool can thus continually be avoided.
Abstract: A longitudinally split cylindrical sleeve, consisting of two half shells, is applied to an internally pressurized pipe, to reinforce a section of the pipe wall weakened by an internal or external defect. One pair of adjacent shell ends are first welded together along their length with the shells in place on the pipe in a relaxed condition. The other pair of adjacent shell ends are equipped with longitudinally extending, outwardly projecting, attached shoulder lugs. A clamp assembly is applied to the shoulder lugs to draw them together and tension the sleeve about the pipe. The clamping force applied to the shoulder lugs is monitored and terminated when the applied stress in the sleeve is approximately equal to the stress exerted on the pipe wall by the internal fluid pressure. The free ends of the shells are then welded together longitudinally while in the tensioned condition. The sleeve/pipe combination forms, in effect, a thick-walled cylinder.
Abstract: A toilet seat cover is provided for preventing contact between the human buttocks and the toilet seat when the sheet is disposed and aligned with the toilet seat. A microbiocidal shield is created by the perspiration from the buttocks contacting a water-soluble oxidizing agent along with a water-soluble ene-diol compound dispersed as separate particles in the sheet. The water-soluble oxidizing agent and water-soluble ene-diol compound may be separately microencapsulated by a protective film. Capillary action of the fibers in the sheet provide for conducting free water released during reaction between the water-soluble oxidizing agent and the ene-diol compound throughout the toilet seat cover. Fibers of the sheet are adhesively bonded together within the adhesive that is soluble and dispersible in water to enable the toilet seat cover to be flushed down the toilet after use.
