摘要： The preferred embodiment is to a battery separator for a nickel metal hydride (NiMH) battery. The separator includes a wettable, resilient nonwoven web having two spunbond layers sandwiching a melt blown layer. The web has a puncture strength of greater than 6 newtons, a tensile strength of greater than 200 newtons/meter, and an average pore size of less than 20 microns.

摘要： The present invention provides improved methods of treating subterranean formations using borate cross-linking compositions and borate cross-linked well treating fluids. The borate cross-linking compositions are basically comprised of a low viscosity hydrocarbon liquid, an organophillic clay, a slightly water soluble borate, a buffer and a dispersing agent.

摘要： The present invention provides borate cross-linked well treating fluids and methods of preparing and using the fluids in treating wells such as fracturing subterranean zones therein. The improved cross-linked treating fluids are basically comprised of water, a hydrated galactomannan gelling agent and a borate composition for buffering the treating fluid and cross-linking the hydrated galactomannan gelling agent comprised of water, a soluble boron source and an alkanolamine or alkylamine.
