  • Patent number: 5867848
    Abstract: A thermochromic urinal display apparatus and method for displaying a message when activated by a warm urine stream and terminating the display when the apparatus is rinsed with cool rinse water. A urinal display screen is disclosed with advertisement, slogans, public service messages either painted, printed, screened or incorporated onto the urinal display screen using thermochromic paint, ink, film or decal. The urinal display screen is placed so that the thermochromic display is above the water line in the urinal reservoir. The warm urine stream activates the thermochromic paint to induce opaqueness or clarity to reveal advertising slogans, public service messages to the user. Once flushed the cool water from the urinal rinse deactivates the thermochromic paint so that it returns to its original state thereby becoming opaque to conceal an underlying message from the next user.

  • Patent number: 5829952
    Abstract: A reversible valve ball assembly for use in a down-hole pump oil field check valve. The reversible valve ball can be removed, inverted and reinserted into the check valve to provide a new valve ball sealing surface. The reversal of the valve ball is performed after the original valve ball sealing surface has worn and deteriorated so that it can no longer seat properly to form a seal between the valve ball surface and a valve seat. The valve seat is also reversible. A set of irregularly shaped valve ball guide arms are provided which rotate within valve guide apertures to provide a cleaning action between the valve guide apertures and valve ball arms to prevent accumulation of debris which tends to immobilize the reciprocating valve ball. An elongated gas-breaker fin is provided and can be used to prevent gas lock. The gas-breaker fin enables a reduced vertical length for the valve ball arms so that a reversible symmetric valve ball assembly can be utilized.
