Abstract:

A multilayer coating has a first coating layer deposited on a substrate; a second coating layer deposited on the first coating layer; and a third coating layer deposited on the second coating layer. The first coating layer is substantially a metal, the second coating layer is a mixture of the metal and a polymeric material, and the third coating layer is substantially the polymeric material. The substrate is at least one of iron, iron pipe, steel, copper, nickel, concrete, wood, wood products, fiberglass, ceramic, plastic, and any other metal or non-metal material that can be used as a substrate, and the metal is at least one of zinc, aluminum, magnesium, indium, gallium, tellurium, and alloys thereof, whereby the metal used is anodic to the substrate.

Abstract:

A concentrically multi-shafted apparatus compresses a compressible stopper to effect a seal in a through-hole of a main utility line to permit a substantially leak-free removal and replacement of a service saddle or a service seal. Counter rotation of concentric shafts, depending upon the direction of rotation, increases or decreases an axial load on the compressible stopper. The external concentric shaft is in sealing engagement with a housing which, when coupled to a utility customer's gate valve permits a main line through-hole to be sealed by the compressible stopper without leakage of water or gas. Once the through-hole is sealed, the service saddle can easily be removed and replaced.
