Abstract: A connector system is configured for macro motion. Two mating terminals are configured so that during macro motion cycles, the resistance between two terminals does not substantially increase. One terminal can have multiple, somewhat spherical-shaped mating surfaces while a mating surface on the other terminal can be flat. The mating terminals can be configured to provide desirable resistance performance after more than 5000 cycles of macro motion.

Abstract: An article of manufacture includes an active solar area having a number of photovoltaic (PV) cell sets. Each of the PV cell sets includes one or more PV cells, and has a PV cell set area. Each of the PV cell sets includes a spacing distribution, where the spacing distribution is such that a geometric shape having a predetermined characteristic area value cannot be positioned to cover an area greater than a reverse biasing fraction of the PV cell set area corresponding to the PV cell set.

Abstract: An article of manufacture (400) includes a number of photovoltaic cells (102) forming a photovoltaic (PV) module circuit, with a first bus bar (106) electrically coupled to one extremity of the PV module circuit and a second bus (206) bar electrically coupled to a second extremity of the PV module. The bus bars (106, 206) are positioned on an opposing side of the PV cells (104, 204) from a light incident side of the PV cells.

Abstract: A composition includes specific amounts of a virgin poly(arylene ether) resin and a rubber-modified polystyrene that is preferably derived from post-consumer recycling. The composition includes about 0.2 to about 1.5 weight percent of polymerized acrylonitrile residue that can originate as a contaminant in the recycled rubber-modified polystyrene. The composition avoids the need for compatibilizing agents required by related compositions.

Abstract: A profile extruded article includes a composition that is formed by melt-kneading particular amounts of a poly(arylene ether), a polystyrene-poly(ethylene-butylene)-polystyrene triblock copolymer, a homopolystyrene, and a polysalicylate. The article is particularly useful in the fabrication of solar collectors for low cost solar energy systems.

Abstract: A method of preparing a purified dianhydride is provided where said method comprises the steps of preparing a first mixture comprising water, at least one inorganic acid, and at least one dianhydride, said dianhydride comprising at least one impurity which is soluble in aqueous acid heating said first mixture until substantially all of said dianhydride is converted to a tetraacid comprised in a second mixture; filtering at least a portion of said second mixture to provide a solid tetraacid and a filtrate, said filtrate comprising at least a portion of said impurity; and heating the tetraacid provided in a solvent with concurrent distillation of water to provide a third mixture comprising a purified dianhydride and a solvent.

Abstract: A method for making a polyarylene ether copolymer including mixing a polyarylene ether, a hydroxyaromatic terminated siloxane reagent and an oxidant, and melt compounding the mixture. A polyarylene ether copolymer including a polyarylene ether, a hydroxyaromatic terminated siloxane reagent, an oxidant and a filler is also presented.

Abstract: A method of preparing a capped poly(arylene ether) is described. By controlling the order of addition and rates of addition of reactants, solvent, and catalyst, problems associated with known methods are avoided. The method is particularly suitable for large-scale preparations of a capped poly(arylene ether).
