A method for improving the adhesiveness between a polyolefin resin and a sized glass fiber which comprises forming a mixture of the resin, a fiber and an organic acid and molding the mixture.
The adhesion of textile fibers to unsaturated polymers is made possible by use of an adhesive which comprises a blend of one or several elastomer latices and a phenoplast system based on a precondensate of formaldehyde, resorcinol and a para-substituted phenol having one or two active methylene groups and a precondensate of formaldehyde and resorcinol.

The addition of copper, either as a thin film or as an alloy constituent, to nickel-chromium alloys improves the adhesion of such alloys to polymeric substrates and coatings.
A process for applying copper to a substrate of aluminum or steel by electrodeposition and for preparing an aluminum or steel substrate for electrodeposition of copper. Practice of the invention provides good adhesion of the copper layer to the substrate.
The wellbore, fractures, and adjacent matrices are soaked with solutions of aliphatic amines for several hours, after which they are pushed by a slug of solvent into the formation matrix. Subsequently, normal production is resumed. This treatment prevents scale accumulation on the treated surfaces, whereas untreated surfaces will accumulate copious quantities of the precipitating solid. The chemical nature of the treating compound is such that the compound tends to migrate from the treatment sol...
The subject invention involves pharmaceutical compositions comprising a sulfated glyceroglucolipid having the structure: ##STR1## wherein n is an integer of from 1 to about 5, R is hydrogen or C.sub.1 -C.sub.24 acyl or alkyl, R' is hydrogen or C.sub.1 -C.sub.24 acyl or alkyl, and M.sup.+ is a cationic moiety, and methods of treating or preventing gastroduodenal diseases or disorders caused by or associated with H. pylori by administering such compounds.
In an isotope separation system in which hot, isotopically separated vapor is deposited on enriched product and depleted tails plates, deposit adherence is improved and plate cooling simplified. The tails plate is liquid-cooled to a lower temperature which permits the product plate to be radiatively cooled by it simplifying product plate cooling and lowering its temperature to reduce the tendency for the product plate deposit to separate during temperature cycling. In one embodiment plate surfac...
A method for selectively bonding layers of polymeric material, especially expanded polytetrafluoroethylene (ePTFE), to create endoluminal vascular devices. In a preferred method the selective bonding is achieved by applying pressure to selected areas using a textured mandrel. This permits a stent device to be encapsulated between two layers of ePTFE with unbonded slip pockets to accommodate movement of the structural members of the stent. This allows stent compression with minimal force and prom...
A process for measuring the bond of a coating on a substrate. Ultrasound echoes through the substrate of a test piece are collected and their amplitudes are measured, their decay being a function of the bond of a coating deposited on the opposite face of the substrate. Preliminary tests on calibration test pieces give a correlation function so that it is unnecessary to carry out expensive and uncertain mechanical tests on the test pieces.
