    摘要： A laminated air brake tubing includes inner and outer nylon layers with an intermediate fiber reinforcing layer. The tubing further includes one and preferably two layers of high density polyethylene positioned adjacent either of said nylon layers with a protective layer separating the fiber reinforcing layer from the high density polyethylene layer. The protective layer is preferably a thin layer of nylon or nylon alloy. Further, the high density polyethylene layer may include compatibilizing agents preventing delamination. The air brake tubing of the present invention meets the current requirements for air brake tubing, however it is less expensive than currently available air brake tubing.

    摘要： A method of manufacturing angiographic catheters comprises providing a length of elastomeric tube of a predetermined outer diameter and braiding multiple strands of wire wrapping about its exterior. A plastic bonding agent is extruded onto the entire length of the wire wrapping to bond the strands to each other. Thereafter, the wire wrapping is ground away at predetermined spaced locations along the length of the elastomeric tube to provide a series of wire wrapped sections joined by non-wrapped sections. An elastomer layer is disposed over both the wire wrapped sections and the non-wrapped sections throughout the length thereof. Subsequently, the coated length is severed into pieces with the pieces each constituting unitary construction including a wire wrapped section that forms a catheter body and a non-wrapped section joined to at least one end thereof to constitute a flexible catheter tip.

    摘要： Methods for preparing abrasive articles and novel methods of making abrasive articles are presented. One method includes inserting a fibrous material adjacent an interior surface of a drum. A composition comprising an organic binder precursor material is then placed in the drum, and the drum is rotated such that centrifugal forces distribute the composition, including the organic binder precursor material, uniformly about the fibrous material. The composition is exposed to conditions sufficient to solidify the organic binder precursor material such that an endless, flexible, seamless substrate is formed having an outer surface formed adjacent the interior surface of the drum, an inner surface opposite the outer surface and the fibrous material embedded therein. Coated abrasives formed by this method, as well as other methods, are provided wherein an effective amount of a fibrous reinforcing material is engulfed within an organic polymeric binder material. Sufficient binder is present such that there is one or more regions of organic binder material free of fibrous reinforcing material, to which abrasive particles are attached.

    摘要： A double walled storage tank system has two closely associated discreet walls with a closed communication space therebetween. The system comprises (a) a tank having a main body side wall and attached end walls, (b) a continuous wall of a fibrous reinforced resinous material which substantially follows the contour of at least a portion of the tank and (c) an array of interlocking filament bundles disposed between the tank and the continuous wall. The array has a first face bonded to a tank wall and a second face bonded to the continuous wall. A mid-portion of the array is in a substantially unbonded state to create the closed communication space for leak detection purposes. The strength of the double walled storage tank system is substantially enhanced by the array securely bonded to both the tank wall and the continuous wall and by its own inherent tensile strength.
