Abstract:
A method of manufacturing a polymer foam composite is described, the method comprising forming an article having a first surface and an opposite second surface from a precursor composition, the precursor composition comprising a polymer foam precursor composition, and a filler composition comprising a plurality of magnetic, electrically conductive particles; foaming the precursor composition to form a plurality of cells in precursor composition; applying a magnetic field to the foamed precursor composition, wherein the magnetic field is of a strength and applied for a time effective to align the electrically conductive, magnetic particles into mutually isolated chains between the first surface and the opposite second surface of the article; and solidifying the polymer foam precursor composition to provide a polymer foam composite having a density of about 1 to about 125 pounds per cubic foot and a volume resistivity of about 10−3 ohm-cm to about 103 ohm-cm at a pressure of 60 pounds per square inch. Polymer foam composites made by this method are also described, as well as articles formed therefrom.
Abstract:
Articles are disclosed, comprising a polymer foam layer having a first surface and an opposite second surface; a plurality of cells between the first surface and the opposite second surface of the polymer foam layer, wherein the thickness of the polymer foam layer between the first surface and the opposite second surface is 1.0 to 1.5 times the average height of the plurality of cells; and a plurality of magnetic, electrically conductive particles aligned into a plurality of mutually isolated chains that essentially continuously span the foam between the first surface and the opposite second surface of the polymer foam layer. The foams are useful as gaskets for electromagnetic shielding, grounding pads, battery contact conductive spring elements, and the like.

Abstract:
Hyperclusters are a cluster of clusters. Each cluster has associated with it one or more resource groups, and independent node failures within the clusters are handled by platform specific clustering software. The management of coordinated failovers across dependent or independent resources running on heterogeneous platforms is contemplated. A hypercluster manager running on all of the nodes in a cluster communicates with platform specific clustering software regarding any failure conditions, and utilizing a rule-based decision making system, determines actions to take on the node. A plug-in extends exit points definable in non-hypercluster clustering technologies. The failure notification is passed to other affected resource groups in the hypercluster.

Abstract:
A silicone grip comprising a cured silicone film layer with a Shore A Durometer of less than or equal to about 60 wherein the silicone film layer is formed from a curable silicone composition comprising a catalyst that promotes cure of the silicone composition, a higher molecular weight organopolysiloxane having at least two alkenyl groups per molecule, a lower molecular weight organopolysiloxane having at least two alkenyl groups per molecule, and an organopolysiloxane having at least two silicon-bonded hydrogen atoms per molecule. The cured silicone layer is used in combination with an adhesive to provide a flexible and malleable grip, and/or in combination with a backing layer that can be solid or foamed.
Abstract:
A bracket assembly for connecting an overhead roof structure to below roof structure elements of a building. The below roof structure elements include a wall having a top plate member or ceiling support structure. The bracket assembly includes overhead fixing members, a bracket member, bearing member, sleeve member, and below roof structure fastener, which are interconnected and fastened together. One end of the bracket member is connectable to the overhead fixing members to the overhead roof structure and the other end is connectable to the below roof structure fastener which is connectable to the below roof structure. The bearing and sleeve members are located and connected between the bracket member and the below roof structure such that the bracket member rests without loading on the bearing member which then rests on the sleeve member which when used rests without loading on the below roof structure, providing structural integrity.
