  • Patent number: 4275471
    Abstract: This invention comprises an improved hydraulically operated flush valve for toilet flush tanks and similar devices. Its main components are a cylinder and piston assembly positioned with its longitudinal axis directly above and vertically aligned with the vertical axis of the outlet or flush tube of the flush tank. The moveable piston within the fixed cylinder acts as the moving and sealing element of the flush valve. By means of an inner valve connected to the flush tank operating lever hydraulic force is caused to lift the piston thereby opening the flush valve. There is no direct mechanical connection between the operating arm and the flush valve, and there are no chains or hinges. There is a positive permanent flush valve alignment and a minimum of friction. In addition, the amount of water used per flushing action can be regulated to prevent water and energy wastage.

  • Patent number: 4275474
    Abstract: Provided is a vacuum head for a swimming pool cleaning system, the head being of the bristle-type for use particularly on vinyl liners, and the like, and comprising a wide, substantially shallow structure including an elongated top, walls and an outlet oriented upwardly from the top and communicating with the generally hollow interior of the head, the upright outlet forming a first connection for attachment of a vacuum hose to the head. A second hose of a diameter smaller than that of the first hose may be detachably positioned over an adapter member which is removably fitted within the first hose connection. Suction control in the form of at least one water by-pass valve is provided in the head top, enabling water sucked into the head interior to be selectively released therefrom, thereby preventing an excessively high suction force in the head intake area and such a force resulting from too great a build-up of vacuum within the cleaning system.

  • Patent number: 4275476
    Abstract: A molded ice scraper one piece body has independently flexible finger portions terminating in aligned scraping edges that are joined by webs a few thousandths of an inch thick. A continuous, but breakable, blade is thereby formed that will clean a streak-free swath on a windshield or similar surface. The slots separating the fingers are curved where they meet the scraper intermediate section, to eliminate stress concentration. The fingers have forward facing ice deflecting surfaces at an obtuse angle to the surface to be cleaned, extending from the scraper edge, and front facing ice chipping surfaces extending vertically upwardly from an intersection with the ice deflecting surfaces that is spaced back from the scraper edge.
