Abstract: The present invention is related to the modifying of substrates with multiple modifying agents in a single continuous system. At least two processing chambers are configured for modifying the substrate in a continuous feed system. The processing chambers can be substantially isolated from one another by interstitial seals. Additionally, the two processing chambers can be substantially isolated from the surrounding atmosphere by end seals. Optionally, expansion chambers can be used to separate the seals from the processing chambers.

Abstract: Compounds that include silicon-containing groups, and optionally urethane groups, urea groups, or combinations thereof (i.e., polyurethanes, polyureas, or polyurethane-ureas), as well as materials and methods for making such compounds.

Abstract: The present invention is related to systems and methods for modifying various non-equidimensional substrates with modifying agents. The system comprises a processing chamber configured for passing the non-equidimensional substrate therethrough, wherein the processing chamber is further configured to accept a treatment mixture into the chamber during movement of the non-equidimensional substrate through the processing chamber. The treatment mixture can comprise of the modifying agent in a carrier medium, wherein the carrier medium is selected from the group consisting of a supercritical fluid, a near-critical fluid, a superheated fluid, a superheated liquid, and a liquefied gas. Thus, the modifying agent can be applied to the non-equidimensional substrate upon contact between the treatment mixture and the non-equidimensional substrate.

Abstract: An autoclavable battery for use with electrical equipment in operative procedures includes a series of electrochemical cells surrounded by insulation and hermetically sealed in a battery case. The insulation has a thickness and thermal conductivity effective to prevent the cells from reaching their venting temperature when subjected to autoclave conditions.

Abstract: A programming environment including a source code programming language comprising a plurality of programming constructs. A first set of constructs within the programming language are for expressing procedural operations performed on specified data. A second set of constructs within the programming language are for expressing complex data relationships of the specified data. A compiler receives programmed source code comprising user-selected and arranged portions of the first and second set of constructs and generating machine readable code capable of implementing the procedural operations and complex data relationships expressed by the source code.

Abstract: The present invention is related to the modifying of substrates such as monofilaments, bundles of monofilaments, and fibrous structural material with a modifying agent. The modifying agent is suspended or dissolved in a supercritical fluid, near-critical fluid, superheated fluid, superheated liquid, or a liquified gas and is deposited by rapidly altering the pressure in a chamber to deposit the modifying material onto the substrate.

Abstract: A medical device comprising a biomaterial formed from a polymer comprising urethane groups, urea groups, or combinations thereof, and sacrificial moieties that preferentially oxidize relative to other moieties in the polymer.

Abstract: The present invention provides a method for modifying a pyrolytic carbon surface to improve adhesion between it and a subsequently added polymer and/or a bio-active compound. In particular, plasma depositing an oxygen-containing, silicon-containing film forming monomer on a pyrolytic carbon surface improves adhesion of a polymer thereto, wherein the modified pyrolytic carbon surface and silicone rubber has a wet adhesion peel force greater than the wet adhesion peel force between an unmodified pyrolytic carbon and silicone rubber as measured by ASTM D 903-49 after 28 days in an aqueous environment, typically, at least 10 times greater.

Abstract: A butterfly valve and associated controls for controlling the flow of water from a large diameter fire hose to the inlet of a fire pump is disclosed. The valve is installed between the suction tube and the suction tube extension of a midship mounted fire pump on a fire truck in a location such that the valve is positioned behind the pump operator panel. A pressure relief valve and an air bleed are mounted on the body of the valve.

Abstract: The present invention provides electronically conducting polymer films formed from photosensitive formulations of pyrrole and an electron acceptor that have been selectively exposed to UV light, laser light, or electron beams. The formulations may include photoinitiators, flexibilizers, solvents and the like. These solutions can be used in applications including printed circuit boards and through-hole plating and enable direct metallization processes on non-conducting substrates. After forming the conductive polymer patterns, a printed wiring board can be formed by sensitizing the polymer with palladium and electrolytically depositing copper.

Abstract: A new Vehicle-Mounted Snow Plowing System for improving the driveability of a vehicle in snow by clearing snow away from the intended path of the wheels of the vehicle. The inventive device includes a vehicle mount removably mounted to the front of a vehicle, and a pair of snow deflector assemblies removably mounted to the vehicle mount. The snow deflector assemblies are mounted ahead of and in line with the front wheels of the vehicle. Furthermore, the snow deflector assemblies are moveable between a lowered, operative position and a raised, stowed position.

Abstract: The mechanism includes a pair of gates which are horizontally spaced from one another and which are operable to stroke between inwardly extended and outwardly retracted positions for collecting and dropping the articles, respectively. The gates are mounted on a threaded member for selective horizontal adjustment of the distance between the gates to enable collection of articles of various widths. As an incident to adjusting the distance between the gates, the stroke of the gates is simultaneously adjusted.
