Abstract: In a positive drive power transmission system composed of a toothed belt and two or more pulleys, operating noise resulting from the impact of the belt and the pulleys is dramatically reduced by having surface discontinuities on either the belt or on the pulleys on those surfaces where the belt and the pulleys engage in impact contact when in operation. The surface discontinuities may be formed by recessed or raised portions of the belt or pulleys, may be straight or curved, and may be substantially parallel to the tensile member or at an angle thereto. Several methods of manufacturing belts with such surface discontinuities are disclosed.

Abstract: A belting fabric having enhanced longitudinal and transverse rigidity includes closely adjacent, substantially uncrimped, warp cords in upper and lower planar arrays, and substantially uncrimped weft cords in upper, lower and middle planar arrays alternating with the arrays of warp cords. The cord to cord spacing in the middle array of weft cords is half that in the upper and lower arrays of weft cords, each upper weft cord is located midway intermediate two adjacent lower weft cords and vice versa, and each middle weft cord is located midway intermediate an upper weft cord and an immediately adjacent lower weft cord.

Abstract: A pulley configuration which increases the contact area between the pulley tooth tips and the land area of the belt teeth. The increased contact area reduces land area wear between belt teeth. The pulley tooth tip has a longitudinal cross-sectional contour partially composed of two substantially circular arcs connected by a line segment which is substantially straight or slightly curved. The length of the line segment is from 5 percent to 100 percent of the width of the belt tooth on which the pulley is used, and preferably between 6 percent and 33 percent of the width of the belt tooth. The pulley in combination with a toothed belt forms a positive power transmission system.

Abstract: The ends of two sections of lined pipe (e.g. polyurethane lined steel pipe), in which the lining terminates a definite distance from each pipe end, are butted together, with an internal concentric sleeve spanning the unlined pipe ends and defining an annular hollow casting space at the area to be joined. The butted ends are then welded together at the joint. Thereafter a curable liquid polymer (e.g., liquid polyurethane composition) is introduced into the casting space through an opening in the unlined section of the pipe, and cured to a solid state in situ. The opening is then plugged.
