  • 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.

The STW compositions are substantially free of detersive surfactants and silicone materials. The STW compositions can further comprise a particulate co-softening compound having an average particle size of less than about 800 microns in diameter. The STW compositions comprise an effective amount of the particulate fabric softening active and optional particulate co-softening compound to provide a concentration of the fabric softening active and optional co-softening compound of at least about 50 parts per million when the STW composition is dispensed in a wash solution of the laundering process.

  • 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.
