Publication number: 20110311761Abstract: A parallel passage fluid contactor structure for chemical reaction processes has one or more segments, where each segment has a plurality of substantially parallel fluid flow passages oriented in an axial direction; cell walls between each adjacent fluid flow passages and each cell wall has at least two opposite cell wall surfaces. The structure also includes at least one active compound in the cell walls and multiple axially continuous conductive filaments either embedded within the cell walls or situated between the cell wall surfaces. The conductive filaments are at least one of thermally and electrically conductive, are oriented in axially, and are in direct contact with the active compound, and are operable to transfer thermal energy between the active material and the conductive filaments. Heating of the conductive filaments may be used to transfer heat to the active material in the cell walls. Methods of manufacturing the structure are discussed.Type: ApplicationFiled: February 26, 2010Publication date: December 22, 2011Inventors: Andre Boulet, Soheil Khiavi

Patent number: 8075979Abstract: A non-fibrous ultra high molecular weight polyethylene tape having a width of 1-inch or greater and a modulus of 1,400 grams per denier or greater. The non-fibrous UHMWPE tape is obtained by compression molding ultrahigh molecular weight polyethylene powder at a temperature below its melting point and then drawing and stretching the entire resultant compression molded UHMWPE sheet, with no slitting or splitting of the sheet, at a draw ratio of at least 100:1. The UHMWPE tape can be produced in weights of 6,000 to 90,000 denier or greater. The UHMWPE tape of the present invention minimizes the effect of stress concentrators that are prevalent with fibers and thereby enables the tape to be drawn at much higher draw ratios than is possible with fibrous UHMWPE. When used in ballistics panels, the high modulus high molecular weight polyethylene tape of the present invention improves ballistic performance by providing enhanced dissipation of the impact energy of a projectile.Type: GrantFiled: July 8, 2011Date of Patent: December 13, 2011Assignee: BAE System Tensylon H.P.M., Inc.Inventors: Gene C.
