Abstract: A chain belt construction, a load block therefor and methods of making the same are provided, the chain belt construction comprising a plurality of interleaved sets of links, each set of links having a transversely disposed pivot pin arrangement joining its links to the links of the sets of links adjacent thereto, and a plurality of load blocks respectively interconnected to certain of the sets of links to be carried thereby, each load block having a tubular opening arrangement therein telescopically receiving the pivot pin arrangement of its respective set of links therein to interconnect that load block to its respective set of links.

Abstract: A polymeric product having a fabric layer and method of making the same are provided, the fabric layer being provided with opposed sides and at least one polymeric part secured to the fabric layer. The fabric layer comprises a first substantially planar layer of threads disposed in superimposed relation with a second substantially planar layer of threads whereby the threads of the first layer are not woven with the threads of the second layer, the polymeric part effectively being the sole securement that secures the threads of the first layer to the threads of the second layer and thereby imparting its flexible characteristic to the securement between the threads of the first and second layers.

Abstract: An apparatus and method for measuring the angle of at least one side surface of an endless power transmission belt construction of a V-belt type is provided, the apparatus having a first part against which the belt construction is adapted to be disposed in a belt construction measuring position thereof and having a second part pivotally mounted to pivot on an axis thereof and being adapted to be pivotally disposed against the one side surface to indicate the angle thereof by the relation of its pivoted position relative to a reference when the belt construction is against the first part in the measuring position thereof, the apparatus having a moving device operatively interconnected to the second part to tend to move the same toward the belt construction in a direction substantially transverse to the axis thereof when the belt construction is in the measuring position thereof. A method of making such an apparatus is also provided.

Abstract: An apparatus for measuring the angle of at least one side surface of an endless power transmission belt construction of the V-belt type and a method of making such apparatus are provided, the apparatus having a first part against which the belt construction is adapted to be disposed in a belt construction measuring position thereof and having a second part pivotally mounted to pivot on an axis thereof and being adapted to be pivotally disposed against the one side surface to indicate the angle thereof by the relation of its pivoted position relative to a reference when the belt construction is against the first part in the measuring position thereof. The apparatus has a moving unit operatively interconnected to the second part to tend to move the same toward the belt construction in a direction substantially transverse to the axis thereof when the belt construction is in the measuring position thereof.
