Abstract: A textile gasket and method of construction thereof for establishing a seal between mating members in a high temperature application is provided. The gasket has a knit, tubular body constructed at least in part of non-metallic, heat-resistant yarns. The body extends between opposite ends with at least one of the ends being rolled toward the other end to form a circumferentially extending rolled portion of a predetermined diameter for receipt between the mating members.

Abstract: A hybrid yarn filament used in construction of a sleeve for protecting elongate members against at least one of EMI, RFI or ESD, and methods of construction of the hybrid yarn filament. The hybrid yarn filament has a non-conductive filament and at least one conductive wire filament overlying an outer surface of the non-conductive filament. The hybrid yarn filament is arranged in electrical communication with itself or other hybrid yarn filaments to provide uniform shielding against EMI, RFI, and/or ESD.

Abstract: A low profile fold protective textile sleeve for bundling elongate members has longitudinally and laterally interlaced monofilament warp and fill yarns. Flat profile monofilaments are employed in the warp direction and round monofilaments in the fill direction. The flat monofilaments are considerably wider than they are thick, and provide the sleeve with flexibility and bending out of the plane of the sleeve. The round monofilaments may be sized so that their diameter is about the same as the thickness of the flat monofilaments, and they can be bundled together so that the effective width of each bundle approximates the width of the flat monofilament yarns with which they are intertwined. The round monofilaments are heat-set along at least a portion of their length to provide biased living hinge regions of the sleeve, while also lending strength and stiffness to the sleeve along the fill direction.

Abstract: A fabric sleeve and hybrid yarn filament used in construction of the sleeve for protecting elongate members against at least one of EMI, RFI or ESD, and methods of construction of the sleeve and hybrid yarn filament. The sleeve includes at least one interlaced hybrid yarn filament having a non-conductive filament and at least one conductive wire filament overlying an outer surface of the non-conductive filament. The hybrid yarn filament is arranged in electrical communication with itself or other hybrid yarn filaments to provide uniform shielding against EMI, RFI, and/or ESD.

Abstract: A continuous halogen-free flame-retardant filament and method of forming thereof includes providing MC, a phosphorus compound, and PET, and then, forming a mixture of the MC, phosphorus compound, and PET. And lastly, extruding the mixture to form the halogen-free flame-retardant filament. The filament can be braided, woven or knitted into a variety of fabric constructions, such as, for example, sleeves for protecting wires.

Abstract: A halogen-free flame-retardant compound and method of forming a continuous material therefrom includes compounding poly(ethylene terephthalate) (PET) with fire-retardant ingredients melamine cyanurate (MC) and melamine polyphosphate (MPP). The compound is then formed into pellets and/or extruded as a thin film or sheet, and also as a filament or yarn, including monofilaments and multifilaments.

Abstract: A hammer 28 is provided for a material size-reducing machine of the type including a rotor on which the hammer is individually pivotally mounted. The hammer 28 includes a mounting end 36 having a throughbore for receiving a pivot pin therethrough in connection with the pivot mounting of the hammer on the rotor, an extending portion 40 with the center of mass CGM located therein. The extending portion has a non-linear body portion 44 and a linear body portion 46 with the linear body portion 46 being inclined in a direction opposite to the rotation direction at an angle between 5 to 45 degrees as measured relative to a line RFL extending through the center of the pivot pin and the center of mass CGM of the hammer.

The hybrid yarn filament is arranged in electrical communication with itself or other hybrid yarn filaments to provide uniform shielding against EMI, RFI, and/or ESD.

Abstract: An fire-retardant insulating material and method of construction thereof has a textile fabric fabricated of continuous basalt filaments. The continuous basalt filaments are preferably texturized or twisted. The insulating material may be arranged in any configuration, such as a sheet, panel or sleeve, and may be knit, woven or braided.

Abstract: The thermal performance of the heat transfer element assemblies for rotary regenerative air preheaters is enhanced to provide a desired level of heat transfer and pressure drop with a reduced weight. The heat transfer plates in the assemblies have spaced apart dimples for maintaining plate spacing and oblique undulations with the undulations on adjacent plates preferably extending at opposite oblique angles. The dimples may be on every other plate and alternate between the two sides of the plates or they may be on every plate and all extend to the same side.

Abstract: Heat transfer elements for rotary regenerative heat exchangers are formed with spacing ridges or notches having flow-disrupting indentations in the peaks of the notches formed at selected intervals to project into the flow channels. These projections interrupt the boundary layer and cause turbulence and mixing to enhance the heat transfer. Various methods of forming the indentations are disclosed.
