Abstract: A protective brace for conduit is used to retain a section of conduit in a desired configuration while preventing the section of conduit from becoming kinked. To accomplish this, the protective brace has a pair of u-shaped braces and a collection of detachable fasteners. The two u-shaped braces can be clamped around the section of conduit and then held together by the collection of detachable fasteners. Specifically, the collection of detachable fasteners is connected along the lengthwise edges of the pair of u-shaped braces. Accordingly, the u-shaped braces form a rigid tubular brace that is placed around the section of conduit. Preferably, the two u-shaped braces are designed to retain the section of conduit in a curved configuration.

Abstract: An improved isomerization process for hydrocarbon feedstreams through the use of aqueous-treated ferrierite catalysts is disclosed.

Abstract: Solid membranes comprising an intimate, gas-impervious, multi-phase mixture of an electronically-conductive material and an oxygen ion-conductive material and/or a mixed metal oxide of a perovskite structure are described. Electrochemical reactor components, such as reactor cells, and electrochemical reactors are also described for transporting oxygen from any oxygen-containing gas to any gas or mixture of gases that consume oxygen. The reactor cells generally comprise first and second zones separated by an element having a first surface capable of reducing oxygen to oxygen ions, a second surface capable of reacting oxygen ions with an oxygen-consuming gas, an electron-conductive path between the first and second surfaces and an oxygen ion-conductive path between the first and second surfaces. The element may further comprise (1) a porous substrate, (2) an electron-conductive metal, metal oxide or mixture thereof and/or (3) a catalyst.
