Abstract: A solar array according to this invention includes a solar blanket which is folded into adjacent panels that are hinged together in an accordion-folded mode at parallel hinges. A pair of foldable spines is fixed to the panels and runs the length of the array. The hinges are included in the spine. The spines are mounted at one end to a base plate, and also at the other end to a tip plate. The base plate is intended to be attached to the spacecraft structure with a yoke which will provide required standoff for rotational clearance during sun-tracking. A pantograph deployment structure extends between the two plates. It can be retracted for storage and extended to deploy the blanket. A conductive harness is attached to the blanket to collect current from the panels.

Abstract: Methods, systems, and devices are provided for managing resources in a computing cluster. The managed resources include cluster nodes themselves, as well as sharable resources such as memory buffers and bandwidth credits that may be used by one or more nodes. Resource management includes detecting failures and possible failures by node software, node hardware, interconnects, and system area network switches and taking steps to compensate for failures and prevent problems such as uncoordinated access to a shared disk. Resource management also includes reallocating sharable resources in response to node failure, demands by application programs, or other events. Specific examples provided include failure detection by remote memory probes, emergency communication through a shared disk, and sharable resource allocation with minimal locking.

Abstract: Disclosed is a process for the production of t-butyl acetate and coproduction of methyl acetate or ethyl acetate, directly from MTBE or ETBE, by contacting a mixture of acetic acid, acetic anhydride, and MTBE, or alternatively, ETBE, with an acid catalyst. Unlike the art, disclosed is a route employing a tert-butyl ether as starting material for the desired production or coproduction of tert-butyl acetate. Also unlike the art, acetic anhydride is employed to react with the water of formation from the esterification reaction to control formation of t-butyl alcohol.

Abstract: Methods and systems are provided for combining previously incompatible network protocols without tunneling. In one system, an Internet Protocol (“IP”) stack is modified to include an IP-compatible datagram component IP′ which registers a transfer function with an Open Data Interface (“ODI”) component. A NetWare Core Protocol (“NCP”) stack is similarly modified to include an NCP-compatible component NCP′ which utilizes the registered transfer function. The modified protocol stacks provide IP-compatible connectivity for NCP services without continually converting packets between formats in the manner required by protocol tunneling systems.

Abstract: A process for the recovery of methyl ethyl ketone (MEK) from an aqueous mixture of MEK and ethanol comprising extracting the MEK from the mixture using an extractive solvent selected from the group consisting of isopentane, the o-, m-, m-isomers of xylene, and mixed xylenes. Preferably the extractive solvent is separated from the MFK in the extract by fractional distillation and recycled to the extraction step.

Abstract: An adjustable bed canopy and curtain system including a sheet of fabric, at least four vertical post and a frame member. The frame member has a first pair of "L" shaped tubular members and a second pair of "L" shaped tubular members. Each of the first and second pair of "L" shaped tubular members have a lower elongated portion and an upper elongated portion. Each of the first and second pair of "L" shaped tubular members have a horizontal bar projecting from one of the lower elongated portions and capable of coupling with a horizontal bar of another of the lower elongated portions. The upper elongated portion, of each of the first pair of tubular members, receives the upper elongated portions of the second pair of tubular members when the horizontal bars of each tubular member are coupled. Each of the lower elongated portions, of each of the first and second tubular members, are positioned over one of the four vertical post when the first and second pair of tubular members are coupled.

Abstract: The present invention provides a novel one-step process for preparing substituted aryls which can be used as end-capping monomers for preparing highly branched macromolecule polymers that have highly controlled molecular architectures. The process comprises the steps of (a) reacting an aromatic acid with an activating carbodiimide for a sufficient period of time and under suitable conditions of temperature and pressure to form an activated aromatic intermediate, and (b) reacting said intermediate with a suitable nucleophile for a sufficient period of time and under suitable conditions of temperature and pressure to form said substituted aryl compound.

Abstract: A method for electrolytically plating copper onto a base metal, such as steel (18), utilizing an insoluble anode (16) includes the steps of: providing a pyrophosphate plating solution (14); adding a copper source, copper hydroxide, to the plating solution (14); and passing an electric current through the plating solution between the insoluble anode (16) and the base metal (18) to be plated. The apparatus (10) includes a plating tray (12), a pyrophosphate plating solution (14) including a soluble source of copper, an insoluble anode (16) and a power source (20). A copper plated product (P) is also disclosed and claimed.

Abstract: An axial flow helical screw compressor with a slide valve and slide stop mounted end to end in communication with the intermeshing rotors has means for changing the volume ratio during operation by stepwise movement of the slide stop and for changing the capacity during operation in infinitely variable fashion, both in response to system operating conditions. In the event of interference between the movements of the slide stop and slide valve, the components are designed so that the movements of the slide stop overpowers that of the slide valve.

Abstract: A method of operating an electric drive motor for an axial flow helical screw type compressor having a slide valve member and slide stop member mounted beneath the intermeshing rotors such that the slide member controls communication between the work chamber defined by the rotors and the casing to the outlet port and the slide stop member and the valve member together control the working fluid inlet to the bores of the rotor by sensing the drive motor current and full load operation of the compressor in order to incrementally adjust the slide members in opposite directions depending upon whether or not the motor current is increasing or decreasing to thereby continuously seek the position of the slide members at which such current is at a minimum.
