Abstract:
The present invention provides a fibrous catalyst-immobilization system that can be employed for immobilizing catalysts that are subject to fluid flow within a chemical production process. The fibrous systems can be synthesized using electrospinning and the catalysts are secured in the fibers during the electrospinning process.
Abstract:
The present invention relates to thickened fabric conditioners, which fabric conditioners contain a particular polymeric thickener, which is obtained by polymerizing from 5 to 100 mole percent of a cationic vinyl addition monomer, from 0 to 95 mole percent of acrylamide, and from 70 to 300 ppm of a difunctional vinyl addition monomer cross-linking agent. As compared to such compositions comprising a similar product but obtained from a polymerization reaction using between 5 and 45 ppm cross-linking agent considerable advantages are obtained. Especially, the delivery of fragrance present in the softening composition is more efficiently carried over to the fabrics to be treated.
Abstract:
Provided is, for example, a method for the fabrication of electrical interconnects in semiconductor devices wherein a substrate including two or more transistors having gate regions wherein the gate regions are not exposed (e.g., the gate regions are completely covered by an insulating cap) is provided. An insulating layer overlying the transistors and the active areas is deposited, where upon a hard mask is created and patterned to form a contact plug/interconnect opening over a first active area and a portion of a first transistor immediately adjacent the first active area. A spacer is formed within the contact plug/interconnect opening. Insulating material overlying active areas between transistors is removed. A portion of the gate region of the first transistor is then exposed and interconnect material is deposited within the contact plug/interconnect opening onto the exposed portion of the gate region of the first transistor and the first active area.
Abstract:
A fuel injector unit comprises a follower assembly that includes a sleeve having an internal groove that receives a spring clip. The clip is made with a spring ring stock having a diameter less then the width of the groove so that the sleeve may be freely rotated around the retainer clip held in the groove. The retainer clip has linear portions aligned along the flat walls of a follower subassembly that receives a plunger carried by the follower assembly. The flat walls terminate at an expanded shoulder that limits displacement of the retainer clip to a fixed height of the follower assembly for shipping and handling, while permitting controlled axial movement of the follower assembly and the plunger along the aligned flat surfaces of the follower subassembly.
Abstract:
A magazine well plug used to render a weapon safe and/or to prevent sand, water, and other contaminants from entering a weapon is described. The magazine well plug includes a main body substantially shaped to conform to the interior of a magazine well, an optional flange substantially disposed about the main body, and an optional grip element disposed at one end of the main body facilitating insertion and removal of the plug with respect to the magazine well. The main body and flange are comprised of one or more compressible materials. The main body is dimensionally larger than one or more dimensions within a magazine well so as to require the main body to be compressed in part or whole when inserted into a magazine well. The invention avoids openings inherent with rigid plugs, thereby preventing solid and/or liquid contaminants from entering a magazine well.

Abstract:
A lightning-protected conductive composite fuel tank includes a conductive material arrayed on an outer surface to at least partially cover a fastener centerline. Through holes extend along the fastener centerline through the conductive material and the underlying fuel tank shell. These through holes are countersunk into the fuel tank shell to a depth such that a fastener in a through hole will avoid electrical continuity or communication with the conductive material on the fuel tank outer surface. The gap in the countersunk through holes, between the fastener heads and the coextensive outer surface of the fuel tank, is filled with a dielectric or nonconductive material.
Abstract:
The present invention relates to structures that contain one or more fiber and/or nanofiber structures where such structures can be formed on a wide variety of structures or surfaces (e.g., asperities, flat surfaces, angled surface, hierarchical structures, etc.). In one embodiment, the present invention relates to a process for forming one or more fibers, nanofibers or structures made therefrom on a wide variety of structures or surfaces (e.g., asperities, flat surfaces, angled surface, hierarchical structures, etc.). In another embodiment, the present invention relates to a process for forming one or more fibers, nanofibers or structures made therefrom on a wide variety of structures or surfaces (e.g., asperities, flat surfaces, angled surface, hierarchical structures, etc.) where such fibers and/or structures are designed to sequester, carry and/or encapsulate one or more substances. In still another embodiment, the present invention relates to structures that contain one or more fiber and/or nanofiber structures on asperities where the nanofiber and/or fiber structures are designed to sequester, carry and/or encapsulate one or more substances.

An indicator device for determining the efficacy of an antimicrobial treatment process. The indicator device includes an active agent encapsulated in an encapsulation component. The encapsulation components preferably takes the form of an electrospun nanofiber including a polymer.
Abstract:
The present invention is directed to the use and production of fibers from one or more polymers or polymer composites. In one embodiment, the fibers of the present invention are nanofibers. In another embodiment, the fibers of the present invention are polymer nanofibers that further include at least one active agent or additive contained on, in, or about the polymer nanofibers of the present invention. In still another embodiment, the fibers of the present invention can be used to yield carbon and/or ceramic fibers/nanofibers.
