  • Stabilization of mercury in mercury-containing materials
    Patent number: 4354942
    Abstract: A process for stabilizing in situ soluble mercury in deposits of mercury-containing materials which comprises treating the deposits with a stabilizing amount of an inorganic sulfur compound. Suitable inorganic sulfur compounds include sulfides, alkali metal thiosulfates, alkaline earth metal thiosulfates, iron thiosulfates, alkali metal dithionites, and alkaline earth metal dithionites. These inorganic sulfur compounds react with soluble mercury to convert it to insoluble mercury compounds and substantially inhibit its removal by elution with water from the deposits of mercury-containing material.The process may be used to treat land areas, landfill deposits, or submarine sediment deposits to reduce soluble mercury concentrations to a few parts per billion.

  • Cap for a chimney
    Patent number: 4334460
    Abstract: A cap for a chimney is provided. The cap comprises a heat resistant cover, having a topside and an underside, extending across the chimney in superposed and spaced relation thereto. A support means is attached to the underside of the cover for supporting the cover in superposed and predetermined spaced relation above the chimney. A plurality of adjustable detachable mounting means are attached to the support means for detachably mounting the cover to the chimney. The mounting means are adjustable to accommodate the opening in the chimney. A particular advantage of this cap is that it can be easily installed in variously sized chimneys, and is of simple and inexpensive construction. Additionally the cap has a novel heat resistant cover.

  • Leak-testing method for diaphragm-type electrolytic cells
    Patent number: 4137752
    Abstract: A method for leak-testing synthetic separators for interleaved planar electrodes is described. The method includes installing the separator such as a diaphragm or membrane about the electrodes to create an enclosed chamber within the separator, supporting the electrodes from a supportive cell housing, pressurizing the created chamber to a predetermined pressure with a gas, slowly filling the housing with a liquid to a level above the separator and observing the separator during the filling operation to determine if leaks are present in the separator.
