  • Patent number: 4783859
    Abstract: A flush valve is provided for opening and closing a drain connecting a toilet bowl to a waste holding tank maintained at a partial vacuum. The flush valve is located external to the drain and comprises a pinch or nip mechanism surrounding a flexible section of the drain and an electro-mechanically operated actuator for moving the pinch mechanism to close the drain by pinching it shut or to open the drain by pulling it apart. The actuator includes a motor for moving a piston in opposite directions, and a cylinder having one end connected to the pinch mechanism and another end containing an enclosure. The piston is retained and reciprocable a limited distance within the enclosure, and a spring is interposed within the enclosure to provide biasing means between the piston and the cylinder.

  • Patent number: 4750219
    Abstract: A urinal installation includes a urinal bowl, with a flexible conduit member connected to a drainage pipe normally present in bathrooms or the like, and a means to flush the urinal with water. The urinal bowl is mountable on a support such that part of the conduit forms a trap during storage. When lifted from the support for use, the conduit is straightened, removing the trap and permitting drainage. When returned to the support after use, the device is flushed and the trap restored. Alternatively, a portion of the conduit may be a rigid pipe forming a trap regardless of urninal bowl position.
