Patent number: 6979308Abstract: A scaled-up multi-coaxial fiber bioreactor, and variations of this bioreactor. The device is characterized by a hollow housing and an array of from about 20 to about 400 modules of hollow fibers, where each module includes at least three coaxial semipermeable hollow fibers. The innermost fiber provides a boundary for an innermost compartment which is connected to inlet and outlet ports. Arranged coaxially around the central hollow fiber are several other hollow fibers with their respective compartments, each compartment defined by a respective annular space between adjacent fibers and each including inlet and outlet ports. An outermost compartment for permitting integral aeration is the space between the outer side of the outermost fibers and the inner side of the housing, and has inlet and outlet ports. The hollow housing has inlet and outlet manifolds and flow distributors for each of the compartments.

Patent number: 6825813Abstract: An antenna assembly is formed from at least one antenna and associated conductive connecting element (wires, conductive gel or liquid, etc.) mounted within a deformable membrane that allows the antenna assembly to be installed or fixed within a narrow gap or crevice, wherein the gap or crevice may be subject to harsh environmental conditions. The gap or crevice is preferably a gap or crevice in a closure. The antenna assembly typically has a low profile, and is installed either flush with or within a traffic surface or within ¼″ above the surface. The deformable membrane will yield under force, but return to its original shape once the force is removed. The deformable membrane and antenna assembly will deform to conform to the shape of a gap or crevice into which the antenna assembly is installed.Type: GrantFiled: February 7, 2003Date of Patent: November 30, 2004Assignee: ADS CorporationInventors: Ronald A.

Patent number: 6807494Abstract: A method and system for monitoring and analyzing flow in a sewer system includes the steps of using a monitoring assembly to collect data representative of actual flow volume of a fluid substance in a first location such as a sewer pipe, storing the actual flow volume data in a memory, maintaining previously stored data in the memory, determining a predicted flow volume and comparing the actual flow volume with the predicted flow volume to yield a difference value. The predicted flow volume is dependent on the data selected from the previously stored data and a day and time that corresponds to both the actual flow volume data and the data selected from the previously stored data. The predicted flow volume may also be dependent upon additional data corresponding to a rain event.Type: GrantFiled: March 8, 2002Date of Patent: October 19, 2004Assignee: ADS CorporationInventors: James S. Schutzbach, Patrick L. Stevens
