Abstract: A tack measuring device and method wherein two specimens are brought into abutting contact under a predetermined load, after which the contact is maintained momentarily. The specimens are then separated within a second time interval. A load cell measures the force as a function of time and the tack is measured in terms of velocity times the force integrated over the second time interval.

Abstract: A high angle conveying apparatus including a conveyor belt and a cover belt trained for movement in endless paths of travel. An improved roller assembly is provided for providing fully equalized pressure to the back face of the cover belt for improved performance.

Abstract: A disc brake assembly for use in a vehicle having an axle rotatably journaled in an axle housing wherein a rotatable brake disc is connected to a rim support for rotation along with a tire of the vehicle. A housing is attached to said axle housing and encompasses the brake disc. Such housing has a caliper member which straddles a portion of the outer periphery of the brake disc having piston means moveable into engagement with the brake disc. Coolant means are provided to said housing for directing a flow of coolant into said closed chamber for direction against the brake disc, which is then removed via an exhaust opening to atmosphere.

Abstract: A non-metallic bearing (10) is comprised of a fiberglass reinforced elastomer, preferably a rubber matrix (22), inner portion, or bearing blank (11), and a fiberglass reinforced plastic, preferably an epoxy matrix (33), outer portion, or shell (12). A piece (20) having predetermined dimensions is cut from a sheet (16) of fabric (14) loosely woven from reinforcing glass cords. The piece (20) is bent into a hoop (13) and inserted into a mold casing (21). An elastomer chosen to form the matrix (22) of the bearing blank (11) is injected into the mold casing (21) and cured. The bearing blank (11) is pressed from the mold casing (21) and mounted on a mandrel (25). As the mandrel (25) is rotated a woven reinforcing fabric (26) is wound onto the outer periphery of the bearing blank (11). The fabric (26) is impregnated with a plastic resin chosen to constitute the matrix (33) of the outer shell ( 12).

Abstract: A sole and heel construction such as used on overshoes, boots or shoes having a resilient planar body with a plurality of spaced thin fins that extend transversely across the body. The fins are evenly spaced and uniform in width throughout. All fins are identical and are inclined relative to a horizontal plane such that any weight applied to the sole compresses the fins to trap air between adjacent fins to minimize mud build-up.
