Abstract: A colostomy bag provided with a stoma ring, a gas outlet and an external deodorizing filter in which a vertical baffle is provided intermediate the stoma ring and the gas outlet and extending from the upper marginal wall of the bag and a level slightly below the lowest point of the stoma ring. The baffle is designed to prevent feces from being squeezed sideways and upwardly into the gas outlet and clogging it.

Abstract: A stud system for supporting spray insulation to an exterior surface of a concrete structure is disclosed. The stud includes a wall abutting surface, and a laterally extending web for promoting adherence of foam insulation when applied to either side of the stud. The stud is attached to the structure by anchoring to one or more form ties protruding from the structure, or by driving fasteners into the structure. The stud also includes a second surface which can be used for attachment of exterior finishes such as vinyl siding or stucco.

Abstract: The present invention relates generally to the delulcanization of rubber. More specifically, the present invention relates to a process for the hydro-devulcanization of vulcanized rubber utilizing a rubber swelling solvent, a source of reactive hyrogen and elevated temperature and, optimally, also uses a dispersed molecular-scale hydrogenation catalyst that is introduced into the vulcanized rubber in a catalytically inert form that is soluable in the rubber swelling solvent.

Abstract: A System and a Method of initializing and using that system are described in various embodiments all suitable for use remotely monitoring gas escapes on oil or gas well-sites, particularly as early warning technologies for use in preventing injury to workers or populations adjacent those well-sites. The system efficiently uses the Internet to securely transmit pre-processed data off-site for a range of different uses either directly to well-site operators or via a server for value-added handling of and convenient access by operators and others to information based on the data. The system conserves both IP addresses and communications bandwidth without compromising access to detailed data respecting well-site status.
