Abstract: Systems and assemblies are provided for sealing an interface between a cylinder and a manifold corresponding to the cylinder. The cylinder comprises at least one port. A manifold interface is arranged adjacent to the at least one port. A seal is located inside of a circumferential pocket, wherein the circumferential pocket comprises at least a portion of the manifold interface. A spring is configured to preload the seal radially inward so that the seal stays in contact with the outer surface of the cylinder.

Abstract: Methods and apparatus for generating electricity in which exhaust from gas turbines or internal combustion engines are utilized to power wind machines and thus generate electricity.

Abstract: Interleukin-10 (IL-10) conjugated via a linker to one or more polyethylene glycol (PEG) molecules at a single amino acid residue of the IL-10, and a method for preparing the same, are provided. The method produces a stable mono-pegylated IL-10, which retains IL-10 activity, where pegylation is selective for the N-terminus on one subunit of IL-10 with little or no formation of monomeric IL-10. The method also provides a substantially homogenous population of mono-PEG-IL-10.

Abstract: An assembly of chromatograph components which operate at a uniform elevated or reduced temperature and perform the functions of sample injection, precolumn backflush, analytical column selection, detection in a reduced mass and volume, and with a reduced surface area for reduced power consumption in accordance with use in a portable gas chromatograph is disclosed. Parts of the assembly including a switching valve assembly, a column plate, a thermal cover and a detector block are thermally-linked and those parts of the assembly which contact the sample including the gas chromatograph columns are maintained at a controlled temperature using, for example, an efficient axial heater, a Peltier cooler or a heat pipe and temperature sensors, thereby increasing analytical confidence.

Abstract: A fluid control valve arrangement allowing very complex valve interconnection schemes to be implemented in a small volume is disclosed. The fluid control valve arrangement utilizes seat plates positioned above and below a block to allow creation of three layers of material between valve elements on opposite sides of the block. Since there are three layers of material between blister valve elements on opposite sides of the block, there are two interfaces on separate levels from those levels contacting valve membranes and blister recesses upon which to form interconnection channels. Because each side of the block has one layer allocated for blisters and another allocated for formation of interconnection channels, very complex valve interconnection schemes may be implemented in a small volume.

Abstract: A fishing lure comprising a lure blank enclosed in a cover of resilient cloth with the outer surface of said cover decorated to provide a desired color and appearance for the lure.

Abstract: A fluid flow control valve for use with chemical fluids where avoidance of contaminants is important, is provided. The valve has a flow control chamber divided into an analytical section and a driver section by a metallic foil membrane operating member, clamped between the peripheral rim of the chamber and the upper wall. The foil membrane is movable in response to driver fluid pressure between open and closed positions. The upper portion of the rim which engages the membrane is of relatively small surface area, and is made of a softer material than that from which the membrane and the upper wall are constructed, .about. thereby providing a very effective means of sealing the membrane periphery to the upper wall when tightly clamped. The membrane is of domed shape, and is formed in situ by deformation of a planar metal foil sealingly clamped in position within the chamber, by application of fluid pressure thereto through a port to the chamber.
