Abstract: A rubber gasket slightly larger than the footprint of a standard toilet base. The gasket has central hole for surrounding the soil pipe or connection flange from the toilet. A lip surrounds the gasket and the hole to retain any liquid leaked onto the gasket. Optional extensions to the gasket may be placed under other components of the toilet from which leaks are likely, such as the water supply valves. The gasket pads the toilet from the floor surface and protects the floor from any slow leaks from the toilet. The gasket is particularly useful for protection from deteriorated wax seals between the toilet and the drain flange. Any slow leaks through a wax seal will be captured on the gasket and will thus be evident to observers as wetness on the gasket. Without the flange the slow leak would seep into the floor and the ceiling below, most likely causing major damage before it was detected.

Abstract: An improved process for delignifying and bleaching nonwoody, lignocellulosic material into products digestible by ruminants and ingestible by humans. The process comprises treating the substrate in an alkaline solution for a period of time, separating the wetted substrate from the slurry and then treating the wetted substrate with an alkaline peroxide solution at an initial pH of 8.5 to 11.0 for a period of time, and separating, washing and drying the product.

Abstract: An improved process of purifying the product from an alkaline peroxide treatment process for delignifying and bleaching nonwoody lignocellulosic agricultural residues comprising, optionally washing with water, then lowering and maintaining the pH of the substrate at less than about pH 3.0, then washing sufficiently to remove residual chemicals, separating the product from the wash liquid and, optionally, drying the product.
