  • Patent number: 4106433
    Abstract: The method and apparatus for applying a liquid to a movable web of moisture-absorbent material, such as toilet paper or other roll paper sheet material, includes providing a container for storing a quantity of the liquid to be applied to the web, causing the web and the container to be moved relative to one another to apply the liquid from the container to the web in a first pattern. Simultaneously therewith, the liquid is also applied to the web in a second pattern which is spaced transversely from the first pattern to enable the web to retain its structural strength as it becomes wet.

  • Patent number: 4000526
    Abstract: Toilet flushing apparatus for use in a toilet assembly having a drain valve seat, includes a flush valve assembly for enabling a partial flushing operation to occur for conserving the use of water. The flushing valve assembly includes a floating flapper valve device for sealing the drain valve seat, the floating flapper valve device including an air trapping float chamber and an inlet mounted in fluid communication with the chamber for trapping air in the chamber to delay the closing of the flapper device. A vent mounted in fluid communication with the chamber enables at least some of the trapped air to be released from the chamber for enabling the flapper device to close prematurely, thereby causing a partial flush operation to occur. In one form of the invention, a trip lever assembly directly controls the operation of the floating flapper valve device for full flush operations, and it is adapted to control the vent for a partial flushing operation.
