    摘要： A method and apparatus are shown for lining a tubular member with an elastomeric liner having an outside diameter which is initially greater than the inside diameter of the tubular member. A length of the liner is reduced to a downsized outside diameter by rolling and simultaneously crushing the liner a preselected amount, whereby the liner retains a standard dimensional ratio in the downsized condition. The liner is inserted into the tubular member to be lined and is allowed to expand to substantially its original outside diameter to thereby bond the liner within the tubular member.

    摘要： An improved coating roller, particularly for use in coating photographic compositions onto webs, including a tubular generally-cylindrical roller member and a tubular generallycylindrical insert shrink-fitted into the roller member, such that the interference interface between the members dampens vibrations imparted to the roller. Prior to insertion the OD of the insert is approximately equal to the ID of the roller member within a tolerance of + OR - 0.001 inches. The insert extends axially within the outer member so that at least fifty percent of the inner surface of the roller member is frictionally engaged by the outer surface of the insert.

    摘要： An improved pipe liner and associated methods, including a method of manufacturing the improved pipe liner and a method of lining a host pipe with such a pipe liner. The invention solves the problem of gas permeation through a polymer liner in hydrocarbon service which can result in corrosion of the host pipe and can also cause liner collapse. Corrosion occurs due to contact between corrosive species and the host pipe itself. Gases (307) can also accumulate in an annulus between or within the liner (305) and the host pipe (303) and expand during operational de-pressurisation of the pipeline, causing collapse of the liner. The improved pipe liner comprises a barrier layer (311), which prevents permeation through the liner, surrounding an inner polymer pipe (305A) and optionally covered by an outer polymer pipe (305B). The inner polymer pipe is porous which permits free movement of gas between the internal bore (302) of a lined pipe and the barrier layer, so as to prevent accumulation of gases anywhere in the lined pipe, while ensuring that gases do not permeate to, and damage, the host pipe. The liner can be inserted using Swagelining, roll-down, or any other suitable close-fit lining techniques, without compromising the effectiveness of the barrier layer.
