Abstract: A fan coil block of the present invention preferably includes a fan for drawing air and a cooling device for cooling air drawn by the fan. A flexible air handling system of the present invention preferably includes a fan coil block that is supportable overhead by an overhead support system. The present invention is also directed to an air handling method that includes the steps of providing an overhead support system for supporting overhead devices, defining a return air chase within the interior space of a building, and supporting a fan coil block above or within the return air chase using the overhead support system. The fan coil block draws and cools air from the return air chase and returns the cooled air to a plenum above the overhead support system.

Abstract: A system for converting a snowmobile into a wheeled vehicle is disclosed, and comprises a pair of wheel mounting assemblies for each being mounted on one of the front skid support assemblies of the snowmobile, and a swing arm for mounting on the snowmobile in a manner such that the swing arm is pivotable with respect to the frame. The swing arm has a forward end and a rearward end, and is mountable on the drive shaft such that the swing arm is pivotable with respect to the drive shaft. An axle is mounted on the swing arm toward the rearward end thereof, and a suspension mounting assembly is provided for mounting on the frame of the snowmobile and controlling pivot movement of the swing arm.

Abstract: A reflective Fresnel lens for shaping an incident wave for efficiently delivering the incident wave to an array of receivers, having a wavelength within a predetermined range. The Fresnel lens comprises a ground plate and a plurality of reflective elements formed at various levels of the ground plate. The predetermined range includes millimeter wavelength range, sub-millimeter wavelength range or microwave wavelength range.

Abstract: A ridge waveguide filter having a slow-wave structure. The ridge waveguide has an elongate hollow tube formed of a conductive sidewall. At least a first part of the conductive sidewall periodically is recessed along an elongate direction of the hollow tube, such that a plurality of ridges is formed to project in the hollow tube. The sidewall is fabricated from metallic materials. The hollow tube includes a rectangular hollow tube or a circular hollow tube, for example. The ridges are equally spaced from and parallel with each other. Each of the ridges has a bottom surface parallel with a second part of the conductive sidewall. The second part of the conductive sidewall is opposite to the first part of the conductive sidewall.

Abstract: A distributed interconnect and a method is provided for interconnecting electrical components which minimizes coupling inductance and increases bandwidth. The interconnect includes a transmission line with a first and second conductive transmission element. The first conductive transmission element is disposed between a first and second terminal, and has an impedance characteristic that increases from the first terminal to the second terminal. The second conductive transmission element is disposed between a third and fourth terminal, and has an impedance characteristic that increases from the third terminal to said fourth terminal. The conductive transmission elements are furthermore positioned in parallel alignment with respect to each other.

Abstract: The invention relates to a process for converting Taxol A, B and C to Taxol primary amine which can then be easily and efficiently converted to Taxol A or docetaxel, thereby significantly increasing the yield of these products from biomass. The method includes the removal of the amide from the side-chain with Schwartz's reagent to form an imine, followed by the hydrolysis of the imine to the primary amine. The primary amine can then be converted to Taxol A or docetaxel. New Taxol imine compounds and primary amine salts have been formed by this process.

Abstract: A thermal core (10) including aluminum layer (12) held between two molybdenum layers (14) for dissipating heat from a plurality of chip carriers (22). Core (10) has the ability to withstand excessive vibrational loads while being lightweight. Bonding molybdenum/aluminum/molybdenum layers (12, 14) creates a core (10) having an increased stiffness factor which surpasses military vibrational requirements. Additionally, due to the low density of porous aluminum layer (12), weight limitations set forth by the military can also be met.

Abstract: A process for the conversion of glycoside substituted taxanes to taxol and related compounds that can serve as precursors to taxol. The process includes the oxidation of glycoside substituted taxanes to convert the glycoside to the hydroxyl group. The oxidation can occur in the presence of an acid or followed by treatment with acid. Application of the process to 7-xylosyl taxol ("XT") yields taxol; application to other glycoside substituted taxanes forms compounds that can serve as precursors for taxol. The process includes the formation of certain new taxol related intermediate compounds having a hemialdal at the C-7 site on the taxane ring, which hemialdal can then be converted to taxol or taxol precursors. Since glycoside substituted taxanes are isolated with taxol from naturally occurring biomass, their conversion to taxol using the process of the present invention significantly improves the total yield of taxol from natural sources.
