Publication number: 20110275259Abstract: A crease resistant scrim reinforced coated fabric and associated high density polyethylene (HDPE) tapes that can be used in areas where esthetics are important such as rental tents where the material is constantly folded and installed. The scrim has woven HDPE tapes made from a resin to soften the tape, and a coating comprising a UV masterbatch to resist UV radiation, a Flame resistant (FR) masterbatch to resist fire. The resin with a relatively low flexural modulus and a relatively high Vicat softening point would reduces the scrim's crystallinity and avoids tape shrinkage during coating without overly weakening the tape.Type: ApplicationFiled: January 13, 2011Publication date: November 10, 2011Inventors: Trevor Arthurs, Sherryl Patton

Publication number: 20110259815Abstract: The present invention relates to a method for producing man-made devices which have the properties and functions of biological membranes and membrane proteins, and to the structure of such devices. Briefly, in one aspect of the invention, natural or genetically engineered proteins are incorporated into a polymeric vesicle that is conjugated to a thread to form a vesicle-thread conjugate. The engineered protein is preferably a transmembrane protein embedded in the wall of the polymeric vesicle. The vesicle-thread conjugate is then formed into a membrane or thin fabric having a wide variety of inherent functionality, including the ability to selectively transport and/or filter compounds between fluids. By selecting proteins with specific properties, membranes can be fabricated with a defined functionality including molecular scale addressability via directed electrostatic, electromagnetic, and chemical forces.Type: ApplicationFiled: October 6, 2009Publication date: October 27, 2011Inventor: Carlo D. Montemagno
