Abstract: A power transmission and modulation control system may perform one or more operations including, but not limited to: receiving provider net energy availability data indicative of energy available from a power provider over a time interval; receiving end-user energy demand data indicating: an amount of energy to be provided to at least one powered device, and an end-time by which the amount of energy is to be provided to the at least one powered device; determining one or more time intervals over which the amount of energy to be provided to the at least one powered device can be allocated; and controlling a power regulator to provide the amount of energy to the at least one powered device over the selected time interval.

Abstract: This invention, relates to a one-step process for rapidly repairing structures. The process uses a binder comprising a polyisocyanate-terminated pre-polymer containing a divalent metal catalyst, and preferably a tertiary amine catalyst, which cures in the presence of moisture.

Abstract: The invention relates to foundry binder systems which use modified polyisocyanates. The modified polyisocyanates are prepared by reacting a polyisocyanate with an aliphatic alcohol having one active hydrogen atom. These modified polyisocyanates, along with a phenolic resole resin, are added to a foundry aggregate to form a foundry mix which is shaped and cured with a gaseous amine curing catalyst.

Abstract: The invention relates to modified polymeric aromatic isocyanates having allophanate linkages prepared by (a) reacting a polymeric aromatic isocyanate with a monofunctional aliphatic alcohol to form an intermediate modified polymeric isocyanate; and (b) reacting the intermediate modified polymeric isocyanate at an elevated temperature in the presence of a divalent metal catalyst. The invention also relates to foundry binder systems which use these modified polyisocyanates. These modified polyisocyanates, along with a phenolic resole resin, are added to a foundry aggregate to form a foundry mix which is shaped and cured with a gaseous amine curing catalyst by the cold-box process.

Abstract: The invention relates to amine modified polyisocyanates having urea linkages and their use in foundry binder systems. The modified polyisocyanates are prepared by reacting a polyisocyanate with an aliphatic primary or secondary amine. These amine modified polyisocyanates, along with a phenolic resole resin, are added to a foundry aggregate to form a foundry mix which is shaped and cured with an amine curing catalyst.

Abstract: Described is a polycarbonate, polyester, or polyestercarbonate composition prepared from a reaction mixture comprising at least one diol and at least one carbonate precursor or ester precursor, wherein at least about 95 mole percent of the diol present in the reaction mixture consists of one or more aromatic diols, at least about 10 mole percent of which consists of one or more stilbene diols. The composition of the invention advantageously has a relatively high thermal resistance, melting temperature, tensile and flexural properties, and/or resistance to thermal embrittlement. Moreover, the polymers of the invention which are thermotropic liquid crystalline also advantageously possess a broad temperature range for liquid crystallinity, good melt processibility, a low coefficient of thermal expansion, a high ignition resistance, high solvent resistance, and/or good barrier properties.

Abstract: Amorphous polymers which are soluble in organic solvents and can thus be cast as films have high glass transition temperatures which make them suitable for numerous high temperature applications; the polymers comprise ortho aromatic polyketones, polyphthalazines and polyisoquinolines, the polyphthalazines and polyisoquinolines being readily formed from the polyketones.
