Abstract: Dialyzer systems can consolidate multiple technologies and functionalities of blood treatment systems in a significantly integrated fashion. For example, this disclosure describes dialyzer systems that include a magnetically driven and magnetically levitating pump rotor integrated into the dialyzer. Such a dialyzer can be used with treatment modules that include a magnetic field-generating pump drive unit. In some embodiments, the dialyzers include pressure sensor chambers with flexible membranes with which corresponding pressure transducers of the treatment modules can interface to detect arterial and/or venous pressures.

Abstract: The invention relates to curing a binder on fibrous insulation wherein, heated gas flows as a ratio of, an upward flow into the fibrous insulation, and a downward flow into the fibrous insulation, to heat the binder to its curing temperature; and the binder is cooled, thereby curing at least a portion of the binder to a thermoset state. When a remainder of the binder remains uncured, another stage of heating the binder with a ratio of heated gas followed by cooling, will cure the remainder of the binder.

Abstract: An insulation product includes a fibrous web of first fibers, rotary glass fibers, and textile glass fibers. A binder is blended with the fibrous web. The binder bonds the fibers together to form the insulation product. The binder includes a thermoplastic binder component and a powdered binder component.

Abstract: Reinforced fiber insulation is formed by depositing a mixture of textile fiber segments and rotary and/or flame attenuated segments on a surface, mixing a binder with the fibers, and heating the binder to join the fibers together. The low cost process provides a mixed fiber insulation product with improved strength after compression.

Abstract: A method is provided to produce fine diameter glass fibers with fewer defects through a combination of lower attenuating gas velocities and the use of spinners having more and smaller holes. The method uses a device for internal centrifugation of mineral fibers including a centrifuge equipped with a peripheral band perforated with orifices distributed in a plurality of annular zones arranged on top of each other, assuming that the centrifuge is in centrifugation position. The device includes at least two annular zones whose number of orifices per unit of surface area differs by a value greater than or equal to 5%, 10%, or 20%.

Abstract: A method of forming a fibrous insulation product includes forming at least one fibrous veil including first fibers and blowing a non-aqueous, formaldehyde-free, thermoplastic binder in powder, liquid or fibrous form into said veil during said forming step to form a mixture of the binder and the first fibers. When in fibrous form, the binder fibers have average length of less than or equal to about 15 mm. The mixture is collected on the forming belt and formed into an insulation batt, board or molding media.

Abstract: An insulation product is provided comprising an insulation sheet containing randomly oriented fibers bonded together.

Abstract: An insulation product contains a layer of textile, rotary and/or flame attenuated fibers. A process for manufacturing the insulation product includes passing fibrous bundles of one or more of textile fibers and of rotary and/or flame attenuated fibers together through an apparatus that separates the fibers and the mixes the separated fibers. The bundles of rotary and/or flame attenuated fibers can be in the form of specially manufactured mats and/or can be production scraps. The resulting mixture of fibers is formed into a non-woven batt, mat, blanket, or board. The process provides homogeneous fiber product with an improved appearance. The textile fibers can enhance thickness recovery of compressed product. Blends of textile glass fiber with rotary and/or flame attenuated glass fiber exhibit an improved combination of thermal and acoustic insulating performance and adequate strength, at a low production cost.

Abstract: The invention relates to curing a binder on fibrous insulation (108), wherein, heated gas flows as a ratio of, an upward flow into the fibrous insulation (108), and a downward flow into the fibrous insulation (108), to heat the binder to its curing temperature; and the binder is cooled, thereby curing at least a portion of the binder to a thermoset state. When a remainder of the binder remains uncured, another stage of heating the binder with a ratio of heated gas followed by cooling, will cure the remainder of the binder.
