A method of forming a phase change material layer includes preparing a substrate having an insulator and a conductor, loading the substrate into a process housing, injecting a deposition gas into the process housing to selectively form a phase change material layer on an exposed surface of the conductor, and unloading the substrate from the process housing, wherein a lifetime of the deposition gas in the process housing is shorter than a time the deposition gas takes to react by thermal energy.

Substantially uniform hydration and dispersion of high amounts of protein and fiber are achieved while avoiding lump formation, hard textures, and off-tastes in the continuous, mass production of high protein and high fiber content sheetable doughs, and baked goods such as crackers, snacks, and cookies made from the sheeted doughs, by hydrating the protein and fiber with water at a temperature below the denaturization temperature of the proteins, and steaming the hydrated mixture without substantial gelatinization of starch during dough production. The steamed, hydrated mass may be admixed with ingredients comprising at least one flour comprising starch to obtain a dough while avoiding substantial gelatinization of starch of the at least one flour during mixing. The baked goods may have a protein content of at least about 4 g, a fiber content of at least about 4 g, and a whole grain flour content of at least about 4 g per 30 g serving.

The invention provides a continuous-flow process for producing a polymeric material. The process of the invention comprises the steps of: introducing at least two solutions, each comprising one or more reactants, into a microreactor to mix the two solutions to form a reacting solution, wherein the one or more reactants are selected from the group consisting of a monomer, an initiator, a coupling agent, a prepolymer, a macromer, and mixtures thereof; feeding continuously the reacting solution into a flow-through polymerization reactor in a coil form, wherein the flow-through polymerization reactor is capable of providing a residence time sufficient for (co)polymerizing the reactants to form a polymer with a desired polydispersity, wherein the flow-through polymerization reactor is immersed in an ultrasonic bath to minimize or substantially eliminate unwanted high-molecular-weight fractions of the polymer.

The invention provides a method and device for individual yarn spinning at spinning station of a rotor spinning machine.

An improved method of preparing molded seamless breast pads, cups, fronts and the like for use in brassieres and other garments is described. Polyurethane foam sheet, which still contains free isocyanates in its urethane matrix, is sliced from a freshly made foam bun, and placed between the mold parts. The mold parts are then closed by a hydraulic press. Steam is injected through holes in one mold part, and flows throughout the compressed polyurethane foam. Exhaust steam is emitted from holes in the other mold part. Moisture and heat from the steam then accelerate reactions with the free isocyanates and further cure the polyurethane foam material. The polyurethane foam material is therefore molded into the shape of mold parts cavity.

The invention discloses a technique for preparing dichloropropanol by the autocatalytic reaction of glycerol and hydrogen chloride. Glycerol and hydrogen chloride carry out autocatalytic reaction at the temperature of 105 to 160 DEG C and the pressure of 0.05 to 0.5Mpa, and the water generated in the reaction is distilled and removed. The invention also discloses a system for preparing dichloropropanol by the autocatalytic reaction of glycerol and hydrogen chloride gas.

The system can transform glycerol fully and greatly improves the selectivity of dichloropropanol; the purity of the dichloropropanol obtained finally is more than 99.5 percent.

An improved diaphragm-type pneumatic brake actuator includes a flange case, a cover cooperable with the flange case, a flexible diaphragm extending between the flange case and the cover forming a lower pneumatic chamber and an upper pneumatic chamber on opposed sides of the diaphragm. A piston assembly is disposed in the cover for moving a spring between compressed and decompressed positions. A spring guide is disposed between the cover and the piston assembly in the upper chamber. The spring guide prevents direct contact of the spring with the cover to prevent formation of a corrosion cell.

Disclosed is a method and apparatus for reducing the amount of metal catalyzed side-reaction byproducts formed in the feed vaporization and introduction system of a methanol to olefin reactor system by monitoring and/or maintaining the temperature of at least a portion of the feed vaporization and introduction system and/or of the feedstock contained therein below about 400° C., 350° C., 300° C., 250° C., 200° C. or below about 150° C. The temperature can be maintained in the desired range by jacketing at least a portion of the feed vaporization and introduction system, such as at least a portion of the feed introduction nozzle, with a thermally insulating material or by implementing a cooling system.
