  • Patent number: 5866216
    Abstract: Sound absorbent fabric sleeves are formed from interthreaded, preferably braided, resilient, staple spun polymer yarns. Bulk and softness needed for sound absorption is provided through the staple fibers and resiliency desired for expansion capability and shape maintenance is provided through a resilient monofilament core. The yarns are sometimes referred to as dref mono/poly yarns. The sleeves can be heat set to better resist unraveling and maintain tubular shape. The yarns inherently resist fraying. A pressure sensitive or other adhesive layer or an elastomeric material or other material layer can be provided around all or part of the outsides of the sleeves. Spring clips can be provided extending through the tubes between the yarns to assist in mounting the sleeves or to modify them for uses other than sound absorption.

  • Patent number: 5547770
    Abstract: A silicon-enriched aluminide coating for a superalloy article has a composite microstructure including a plurality of bands of silicon rich phases (S.sub.1, S.sub.2, S.sub.3) and a plurality of bands of aluminum rich phases (A.sub.1, A.sub.2, A.sub.3), these bands being spaced apart through the thickness of the coating. The composite microstructure is created by depositing a slurry containing both silicon and aluminum in elemental or pre-alloyed form on the article and heating the coated article above the melting temperature of aluminum to cure the coating, the depositing and curing steps being repeated at least once before diffusion heat treating the resulting layers. Thereupon, all the above process steps are repeated at least once.

  • Patent number: 5545449
    Abstract: Polyether-reinforced fiber-based materials, and methods for their manufacture, are disclosed. A representative material is a sheetlike ply having on one or both faces thereof a polyether-impregnated stratum extending depthwise into the ply thickness dimension no greater than about one-half the ply thickness dimension so as to leave a portion of the ply thickness dimension unimpregnated with polyether. The materials can comprise plural superposed plies wherein at least one ply has at least one polyether-impregnated stratum, such as polyether-reinforced corrugated paperboard. The polyether-reinforced materials have excellent compression strength and foldability. Each polyether-reinforced stratum is made by controllably applying a low-viscosity liquid mixture of an epoxy resin and a hardener, wherein the epoxy resin is substantially non-prepolymerized, to a fibrous web surface, then curing the resin mixture.

  • Patent number: 5543194
    Abstract: An internally pressurizable lightweight high tensile strength multi-layered structure with an outer barrier layer envelope of elastomeric semi-permeable material for use as a cushioning device is provided. The barrier layer is bonded, at a multiplicity of sites, to substantially the entire distal surfaces of a double-walled drop-thread linked fabric wherein the filaments are a highly distorted, long chain, axially orientated crystalline molecular structure which has a low gas permeability. The bond between the barrier layer and the facing fabric is substantially increased by the presence of fibrils and texturizing. The drop threads which are likewise texturized, function to maintain the composite structure in either a substantially flat or planar or contoured configuration without weldments within the select load-bearing areas. This product is capable of withstanding substantial internal inflation pressures, under long-term steady state and cyclical compression and flexural fatigue conditions.
