Said attachment of glove and wash cloth continues down the outer seam of the thumb of the glove, that is, from the wrist to the seam of the thumb.

Abstract: A B-channel for use in a damper frame or sleeve is disclosed which is formed from a blank of sheet metal. The blank has a rectangular barrier wall, a pair of side walls formed along two opposing edges and end walls formed along opposing edges of the barrier wall. The side walls and end walls are folded perpendicularly to the barrier wall and tabs are formed on the end walls to be folded into the planes of the side walls. The B-channel is particularly useful in conjunction with a fire damper sleeve.

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.

The bond layer is formed of a metallic oxidation-resistant material, and has an average surface roughness R.sub.a of at least about 7.5 micrometers, while the ceramic layer is characterized by being segmented by at least two sets of grooves. The grooves have substantially uniform widths of about 100 to about 500 micrometers, with adjacent grooves of each set being spaced about 10 to about 250 millimeters apart.

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.

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.

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.

Abstract: Solar energy absorptive coatings that comprise single cermet layers with a homogeneous metal volume fraction exhibit an absorptance of about 0.8, which is not high enough for practical solar applications. To achieve absorptance greater than 0.9, graded composite films have been developed, but they give rise to higher thermal emittance due to the absorption edge not being sharp enough. This leads to increased thermal emittance at high operating temperatures, in the range of 300.degree. C. to 500.degree. C. There is now disclosed a novel solar selective surface coating which is composed of two cermet layers, with different metal volume fractions in each layer. The two cermet layers have different thicknesses, and the layers have thicknesses and volume fractions such that solar radiation is absorbed by internal absorbing and phase cancellation interference, but the cermet layers are substantially transparent in the thermal infrared region.
