  • Publication number: 20110099703
    Abstract: A toilet flusher for use with a toilet tank that has a fill valve and a bottom drain hole allowing water to flow out controlled by a toilet flush valve, the flusher being installable as the toilet flush valve and including: a longitudinally extendable siphon tube extending longitudinally from a drain hole fitting to a tube inlet with-in a float, such that, when sealingly attached to the tank drain hole by a drain hole fitting, the siphon tube will longitudinally extend upward as it is pulled up by the float floating on water in the tank. The flusher further includes: a float chamber around the tube inlet, the chamber being closed above a top edge of the tube inlet and open below it; floatation means that positions the floating float with the top edge of the tube inlet above the water and the chamber opening below the water.

  • Patent number: 7849664
    Abstract: A system (10) for dispensing dunnage material includes a chute (30) connectable to a supply (20, 40) of flowable dunnage. A container (12) or a bottom of the chute (30) is moved into a dispensing position where the bottom of the chute (30) is proximate the fill plane of the container (12). A controller (16) selectively opens a shutter (50) at the bottom of the chute (30) to dispense dunnage and then closes the shutter (50) to separate the dispensed dunnage from the dunnage in the chute (30) while also removing the dunnage above the fill plane of the container (12). The chute (30) includes at least one substantially horizontal plate member (54) that is openable to selectively vary the size of an aperture (52) created thereby at the bottom of the chute (30) for dispensing dunnage material therethrough.
