Abstract: A sheath-bonding link box is provided, the sheath-bonding link box including a housing defining a sealed interior space, and a set of electrically conductive connectors extending through the housing between an exterior of the enclosure and the interior space. The set of connectors each has an internal portion positioned inside of the interior space and an external portion positioned outside of the housing. The internal portion of the connectors is electrically connectable to a functional link in the interior space, and the external portion of the connectors is dimensioned to be electrically connectable to a sheath-bonding lead.

Abstract: A device, such as a link box, with health monitoring has a housing defining an interior space, at least one surge arrester positioned in the interior space, at least one contactless temperature sensor positioned to contactlessly measure a temperature of the at least one surge arrester and generate temperature data therefrom, and at least one controller connected to the at least one contactless temperature sensor and configured to receive the temperature data.

Abstract: There is provided an oligomeric polyol composition having (a) an oligomeric network containing residues of at least one polyhydroxylated aromatic compound and residues of at least one polyol having at least three hydroxyl groups; and (b) a plurality of peripheral groups having one or more pendant hydroxyl groups bound to the oligomeric network by a plurality of linking units. The residues of the polyol may optionally contain one or more oxygen ether groups, one or more amino ether groups, or both of one or more oxygen ether groups and one or more amino ether groups. Reaction of the oligomeric polyols with isocyanate monomers affords a new class of polyurethanes having superior heat and water resistance. The new polyurethanes exhibit lower peak exotherms, typically less than 250° F. during in-mold polymerization.

Abstract: A mixture of a 1,2,4-triazole-blocked 1,8-diazabicyclo-5.4.0-undecene-7 and a phthalic acid-blocked 1,8-diazabi-cyclo-5.4.0-undecene-7 in a weight ratio of from 5:95 to about 30:70 is a useful polyurethane polymerization catalyst. The catalyst mixture is especially useful in applications in which long open times are needed at temperatures up to about 40° C., to be followed by a fast high temperature cure.

Abstract: Generally speaking, an umbrella having a frame formed by a plurality of rod members joined together by a plurality of hinges, is disclosed. The frame forms a periphery of a shape, such as a circle, square, hexagon, etc., and the frame is capable of movement between a folded configuration and an unfolded configuration. A canopy is attached to the frame, and may be detachable there from, and is also capable of movement with the frame between the folded configuration and the unfolded configuration. A stem having a first end attached to the frame along the periphery and extending there from allows the user to position the umbrella to achieve ideal coverage during use. The stem may include a handle formed at a second end opposite the first end, for improved gripping and control of the umbrella.
