A power transmission belt having a belt body, a tensile cord embedded in the belt body, and a jacket defining a pulley contact surface, where the jacket has been treated on at least the pulley contact surface with an aqueous fabric treatment or dip which includes an aqueous PEEK dispersion as part of the dip. The aqueous dip may further include an epoxy and a rubber latex. The aqueous dip may further include graphene or graphene oxide. The fabric may include aramid or nylon fibers. The jacket may cover the teeth of a toothed belt.

A method and an article of manufacture are disclosed for reinforcing various structures with only partially accessible circumference, such as columns closely adjacent to or protruding out of a wall or beams holding a ceiling. Some of these structures may be partly or completely submerged in water, such as retaining walls on the sides of rivers and water-ways. In some embodiments a prefabricated shell will fully or partly cover the exposed and reachable part of the structure and will be secured in place by various means. The shell may hug the structure tightly or loosely and the space between the shell and the structure may be filled with such curable materials as glue, epoxy, grout, concrete and the like. In various embodiments additional reinforcement such as rebar may be placed in the space between the shell and the structure.

The invention relates to a novel binder system and its use for bonding textile fabrics as well as products containing such bonded textile fabrics. The materials according to the invention are suitable for manufacturing base interlinings which may be used for manufacturing base interlinings for sarking, roofing and sealing membranes, particularly for manufacturing coated sarking, roofing and sealing membranes.
