Abstract: A ball valve member for use in a flush toilet is adjustable to conserve water by varying the amount of water consumed during each flush of the toilet. The ball valve member allows water consumption of a standard flush toilet to be accurately and steplessly varied between about 4 liters and the entire contents of the toilet's tank. The ball valve member has an internal chamber having an air bleed hole at its upper end and a water inlet at its lower end. The water inlet snaps into place at a lower end of the ball valve member and has a inner piece with a D-shaped opening. A cap, also having a D-shaped opening, is rotatably affixed to the inner piece. The size of the water inlet can be varied by rotating the cap to adjust the amount of overlap between the two D-shaped openings. The water inlet can be completely closed to provide a "full flush" and also provides a water inlet which can readily be marked with indicia, such as numeric labels, to indicate the amount of water which will be consumed in each flush of a toilet. The water inlet may be retro-fitted to existing ball valves.

Abstract: Methods of continuously producing sequential lengths of different additive-containing melt-spun filaments include continuously supplying a melt-spinnable polymeric host material to orifices of a spinneret and controllably dosing at least one dispersible additive concentrate systems containing a pigment in a liquid nonaqueous polymeric carrier to the melt flow of polymeric host material upstream of the spinneret orifices.  In such a manner, a first polymeric mixture of the dispersible additive concentrate system and the polymeric host material is obtaine which achieves an additive attribute.  During a first time  interval,  the  first mixture  is  extruded through  the spinneret orifices; and thereafter, during a second subsequent time interval,  the dosing of the at least one dispersible additive is changed so as to form a second mixture having a second additive attribute different from the first additive attribute  while  continuously  supplying  the  melt  flow  of polymeric host material to the spinneret orifices.  The melt-spun filaments will thus have a first length corresponding to the first additive attribute of the first mixture and a  second subsequent length  corresponding  to  the  second  additive attribute of the second mixture.   The methods and additives employed most preferably achieve Hunter Green Purge Values of between about 0.10 to about 1.40 sec/cm3.
