A side-opening sleeve valve having an inner cylindrical barrel with a shaped opening through the wall, an outer cylindrical barrel having shaped opening through the wall, where the barrels are co-annular and rotatable, and a means for rotating the inner barrel relative to the outer barrel between a first open position where the shaped openings overlap to form a side opening into the sleeve valve, and a second closed position where the shaped openings do not overlap. A side-opening valve is used in pigging fluid flush system for a water-less toilet, where a toilet bowl empties into the side opening of the side-opening valve when opened. When the side-opening valve is closed, a pig cleaning system pushes the waste in the side-opening valve to a sewage system.

A flush toilet forms a bowl including a waste-receiving surface and a rim; a rim water passageway and rim spout port for spouting flush water into the bowl and forming a circulating flow are formed on the rim; this rim spout port downstream side flow path changes in curvature from small to large at curved portions formed at positions in the rim inner circumferential wall closest to the rim spout port in at least the right rear area inside the bowl and the front area inside the bowl, and these curved portions are formed by transition curves as seen in plan view.

A new disinfecting sanitary system utilizing an UV-C LED irradiation source is developed for disinfection of pathogens generated by toilet flushing. The disinfecting sanitary system includes a plurality of disinfection devices mounted on a hollow member of the sanitary device, and each of the disinfection devices is configured to emit a beam for disinfection; a control circuit coupled to the plurality of disinfection devices. Each of the plurality of disinfection devices including an ultraviolet light (UV) radiation apparatus configured to project UV radiation towards a target area for disinfection, and the control circuit controls the plurality of disinfection devices to project the UV radiation.

A toilet bowl protective skirt apparatus for protecting and concealing the toilet base includes a cover body having an outer side, an inner side, a top edge, a bottom edge, a left edge, and a right edge. The cover body is substantially flexible to conform to the shape of a toilet. A cover height of the left edge and the right edge is configured to extend from a rim of the toilet to proximal the floor. A plurality of bowl clips is coupled to the curtain. The plurality of bowl is coupled proximal the top edge of the curtain and selectively engages the rim of the toilet.

An apparatus for measuring the flow rate of urine, including an encasement, configured to encase components of the apparatus; a receptacle bowl attached to the encasement, configured to be placed over a toilet bowl or seat, and direct fluid through a single point of exit to a fluid flow guide; the fluid flow guide, configured to transfer fluid from the receptacle bowl to an impeller; the impeller, configured to rotate along a rotation axis, wherein the impeller includes a plurality of blades, configured to receive the urine from the flow guide, and thereby rotate the impeller at a speed correlating with the flow rate of the urine; and an angular velocity sensor, configured to produce electric signals that correlate with the angular velocity or angular position of the impeller.

Disclosed herein is an automated urinary output measuring system. The automated urinary output measuring system includes an automated urinary output measuring device configured to be suspended from a rim of a sanitary hardware device and receive a volume of voided urine. The automated urinary output measuring device can include a receiving trough having an opening, a door configured to cover the opening in a fluid tight seal, the door coupled to the receiving trough by a hinge, and a lip extending from the receiving trough configured to detachably couple the automated urinary output measuring device to the sanitary hardware device. The system can further include an ultrasonic measuring system having a console coupled to one or more ultrasonic sensors, and a flushing mechanism coupled to the sanitary hardware device.

A flush water tank apparatus enabling accurately setting an amount of flush water to be discharged while opening a discharge valve via a discharge valve hydraulic drive unit and a flush toilet apparatus including the flush water tank are provided. A flush water tank apparatus includes a first float device; a second float device that prevents from descent of the discharge valve according to the water level so as to discharge a second amount of flush water; and an adjustment mechanism configured so that when the second amount of flush water is selected by the flush water amount selection portion the clutch mechanism is disconnected at a pull-up height of the discharge valve such that the discharge valve descended by the disconnection of the clutch mechanism is held by the second float device in a holding state.
