A high temperature/high pressure (HP/HT) apparatus for converting feedstock housed in a capsule into product crystals, comprising at least two electrical heating paths for independent control of both the mean temperature in the reaction cell and the temperature gradient across the reaction cell.
Abstract:
An article (20) of a base metal alloyed with an alloying element is prepared by mixing a chemically reducible nonmetallic base-metal precursor compound of a base metal and a chemically reducible nonmetallic alloying-element precursor compound of an alloying element to form a compound mixture. The alloying element is preferably thermophysically melt incompatible with the base metal. The method further includes chemically reducing the compound mixture to a metallic alloy, without melting the metallic alloy, and thereafter consolidating the metallic alloy to produce a consolidated metallic article (20), without melting the metallic alloy and without melting the consolidated metallic article (20).
Abstract:
Disclosed is a spiral wound membrane element (10) that provides two permeate streams through a permeate carrier sheet (20). The spiral wound membrane element (10) is sealed such that the only communication with the permeate carrier (20) is through a membrane sleeve (12). The first permeate stream flows spirally inward and the second permeate stream flows in the opposite direction, spirally outward. The permeate carrier sheet (20) is sealed at two edges so that the permeate streams can only discharge from opposite, unsealed edges of the permeate carrier sheet (20). The first permeate stream may be collected in a central collection tube (16) and the second permeate stream may be collected in a peripheral region of the membrane element (10).
Abstract:
Light source power circuits and EMI filters therefor are presented in which a depletion mode field effect transistor is connected in series with an EMI filter capacitor following an input rectifier to allow filtering of EMI and to limit capacitive currents during triac switching when powered through a phase-cutting dimmer circuit.

Abstract:
A parallel hybrid vehicle includes a heat engine, a transmission including an input and an output, and an electrical device. The transmission input is coupled to the engine and the transmission output is coupled to the electrical device such that substantially all of the torque generated by the heat engine is channeled through the transmission to the electrical device, and a differential, the electrical device coupled to the differential such that during a first mode of operation the electrical device functions as a motor to receive substantially all the torque generated by the engine through the transmission, and such that during a second mode of operation the electrical device functions as a generator to receive substantially all the torque , generated by the vehicle through the differential.
Abstract:
A method for preparing an aliphatic chloroformate comprising, introducing a mixture of at least one aliphatic hydroxyl compound, phosgene, at least one solvent, and optionally at least one organic base into a flow reactor to obtain a unidirectional flowing reaction mixture. The unidirectional flowing reaction mixture is maintained at a temperature between about 0°C and about 60°C to produce a single product stream comprising an aliphatic chloroformate, useful in the preparation of polycarbonates and co-polycarbonates.
Abstract:
A storage medium can comprise a substrate, a reflective layer disposed on a side of the substrate, and data. The substrate can comprise a thermoplastic and a light-mark formed from at least a portion of light-marking additive mixed with the thermoplastic, wherein an optical property of the light-marking additive at an optical drive read wavelength can change due to being contacted with a mark wavelength. A method for using a storage medium can comprise directing a reading device to detect an inspection area of the storage medium, and wherein the inspection area on an authentic medium has a light-mark in a substrate of the storage medium that forms an optically induced signature. The optically induced signature can be converted to a digital identification signature and the digital identification signature can be verified for authenticity.
Abstract:
