Abstract: The present invention 10 discloses an apparatus and method for a storm shelter which can be used aboveground and belowground, and, may be skin supported. The present invention discloses that its top 11, front 13 and rear 15 surfaces can be made from a single, curved piece of material 12, and, that its sides 14 are made from two straight pieces of material all of which pieces are mounted onto parallel curved fine members 18 which are mounted onto a base frame 16 which is anchored to a foundation 34. The storm shelter of the present invention can be manufactured and pre-assembled in an embodiment having a single piece 12, top 11, front 13 and rear 15 construction or in an embodiment having a multiple piece 46 and 48, top 11, front 13 and rear 15 construction designed for on-site construction in the form of a kit or pieces which can be assembled on-site.

Abstract: A novel method and apparatus is provided for treating and/or disinfecting water and/or wastewater wherein the contact chamber is sealed and under greater than atmospheric pressure having a detention time of no more than 5 minutes and further providing for generating a mixture containing chlorine dioxide having a product storage chamber connected to a first mixing chamber which is connected to a first storage chamber for storing chlorite, a second storage chamber for storing organic acid, and a third storage chamber for storing water, metering means are provided between all chambers, and means for filling are provided to these chambers. Unreacted constituents are removed from the disinfecting solution. Outlet means is provided from the product storage chamber to the pressurized contact chamber where the disinfecting solution is contacted with the water and/or wastewater.

Abstract: The present invention describes a novel method and apparatus for treating and/or disinfecting medical wastes wherein the medical wastes may be shredded and the contact vessel may be sealed and may be under greater pressure than atmospheric pressure and may have a detention time of no more than 5 minutes. An organic hydroxy acid or carboxylic acid and an alkali metal or alkaline earth metal chlorite are mixed in the contact vessel. The reaction between the acid and chlorite produces chlorine dioxide which is the active substance used to treat and/or disinfect the medical wastes.

Abstract: Improved multi-wall containers and pipes for transporting fluids which have to be protected against leakage and mechanical forces, have an inner and outer wall separated by a continuous foam layer integrated into the containers. Improved strength and resistance to axial inertial pressure is provided by the method of manufacture using chopped glass fibers, continuous windings of glass fibers and suitable polyester resins and circumferential ribs spaced at stress points and integrally incorporated into the containment walls. Vessels produced according to the methods of the invention have a moment of inertia strength of about 4.67 in.sup.4 substantially eliminating torquing, buckling and rupture.
