  • Patent number: 7854028
    Abstract: A disposable toilet seat cover apparatus is for use on the existing seat of a toilet. The apparatus is provided in a textured biodegradable water soluble material and resists slippage on the seat. A pull tab provides for the gas chamber within the valve assembly of the initially compactly folded apparatus to release a compressed gas to fill the seat cover/cushion. After use, the apparatus' biodegradable makeup provides for either discarding in a trash bin or for deposit into the bowl water, where the apparatus quickly deflates and dissolves. Any of the apparatus not immediately dissolved in the bowl water is easily flushed.

  • Patent number: 6579358
    Abstract: A method of growing protein crystals in a protein crystal growth assembly including a crystal growth cell and further including a cell body having a top side and a bottom side and a first aperture defined therethroug, the cell body having opposing first and second sides and a second aperture defined therethrough. A cell barrel is disposed within the cell body, the cell barrel defining a cavity alignable with the first aperture of the cell body, the cell barrel being rotatable within the second aperture. A reservoir is coupled to the bottom side of the cell body and a cap having a top side is disposed on the top side of the cell body. The method includes steps of rotating the cell barrel to orient the insert in a fill/removal position; loading and securing a protein into the insert; rotating the barrel to a launch configuration position; rotating the barrel to activate and experiment by placing the cell in a growth position; and then rotating the barrel further to deactivate the experiment.
