Disclosed is a toilet bowl water level gauge and associated methods. In one embodiment, the toilet bowl water level gauge comprises a gauge assembly having a stem with a float, and a sleeve, wherein the stem is inserted in the sleeve and slides through the sleeve. Also, the toilet bowl water level gauge comprises a support attached to the gauge assembly, the support being adapted to engage a rim of a toilet bowl. In addition, bowl level sensors are employed for automated calibration of an automated bowl fill system.

A method and apparatus implementing a technique for entering a representation of a desired curve into a computer. In one aspect, the technique includes receiving an ordered sequence of points representing the desired curve as input. The points of the sequence of points are grouped into one or more contiguous segments of points. The points of each segment are smoothed to generate a segment of smoothed points for each segment. One or more mathematical curves are fitted to each segment of smoothed points. Together, the one or more mathematical curves from each segment of smoothed points form the representation of the desired curve.

A toilet tank with a sediment removal assembly comprises a flexible tube connected to the upper discharge spout of the intake standpipe in the toilet tank cavity, and a configured length of copper tubing connected to the flexible tube for water to flow therethrough when the float valve is open to flow water into the tank during a flushing operation. The copper tubing has a longitudinal section which extends downwardly and vertically from its connection to the flexible tube, an integrally joined first lateral or horizontal section curved or bent to lie on the bottom wall of the tank adjacent to the rear wall, and an integrally joined second lateral or horizontal section curved or bent to extend substantially normal to the first lateral section and lie on the bottom wall of the tank adjacent to the then facing end wall of the tank. The lateral sections of the copper tubing include small spaced apart apertures opening inwardly toward the center of the tank cavity, through which jets of water are emitted over the bottom wall of the tank as water flows through the flexible tube and copper tubing. The copper tubing terminates at an open free end adjacent the end wall of the tank along which it lies, such open free end facing the opposite side wall of the tank at its intersecting corner region where it meets the adjacent end wall. When water flows through the flexible tube and copper tubing it is spewed out in a stream directed toward the opposite side wall at the corner intersection. The impact of the water against the opposite side wall in that corner region forces the water to turn and begin to swirl in a circular whirlpool current or stream on the bottom wall of the tank. Such whirlpool current or stream, combined with the jets of water being emitted across the bottom wall of the tank from the small apertures of the lateral sections of the copper tubing, agitate the sediment accumulated at the bottom of the tank, raising the sediment into the whirling stream of water, and carrying the sediment with such whirling stream of water toward the centrally located drain in the bottom of the tank which is open during the flushing operation to carry water to the toilet bowl. Thus, during each flushing operation, sediment in the toilet tank is automatically flushed out of the tank into and through the toilet bowl, and on out the drain conduit leading ultimately to the sewer tile.

A medical tube retention device for securing a tube to a patient. The device is comprised of a band having interior and exterior surfaces and an elastic portion. At least a portion of the exterior surface has a first type of textile fastener covering. A first complementary textile fasting strip is affixed to one end of the band, and a second complementary textile fastening strip is releasably affixed to the opposite end. The textile fastening strips are attached to a tracheostomy or endotracheal tube flange through slots located on opposite sides of the flange. An optional third complementary textile fasting strip, affixed to the first end of the band, is secured to a tube connector and releasably affixed to the opposite end of the band to positively retain the connector to the tube.
摘要:
Heavy metals can be precipitated from waste water or aqueous reaction solutions containing inorganic and/or organic complexing agents with substituted thiorureas of the general formula R.sub.1 R.sub.2 N-CS-NH-COR.sub.3. N,N-dialkyl-N'-benzoyl thioureas are used with preference, whereby methyl, ethyl, n-propyl or isobutyl groups are used as alkyl substituents.
