Abstract: A centerless external honing and/or grinding apparatus wherein abrasive material is flexibly mounted around a longitudinal workpiece-receiving recess for flexibly honing and/or grinding the exterior curved surface of a workpiece while it is fed longitudinally forwardly through the workpiece-receiving recess from an input end thereof to an output end thereof, and adapted to impart a desired type of surface finish, usually what is referred to hereinafter as a plateaued surface finish, to a curved exterior surface of the workpiece, which occurs by reason of the flexible mounting of the abrasive material (usually, abrasive particles) and the self-centering action produced by the centerless honing or grinding construction of three similarly longitudinally oriented, laterally and vertically adjacent roller members arranged cross-sectionally in a generally polygonal (usually triangular) array or configuration and with at least one and, in certain cases two, and in other cases, all three, of the longitudinal roller m

Abstract: A clamp hand protector for use on a pivoting type clamp having an operating handle member pivotally connected to a linkage element of the clamp and defining therebetween an arcuately-variable-angle junction region, wherein an edge-of-hand protective shield is provided with mounting means for positioning the shield between an inner end of the operating handle member and the arcuately-variable-angle junction region so as to prevent injury to an operator's hand when the clamp is moved between clamped and unclamped relationship or vice versa.

Abstract: A multi-directional aerosol valve for use on a pressurized aerosol container (usually a can) to provide for substantially completely emptying such an aerosol can in any selected one of multiple directions, usually ranging between the conventional lateral direction and a vertical direction and, in certain cases, including various different angular directions lying therebetween. This type of multi-directional valve makes it possible to emit the aerosol spray in a variety of different directions and greatly facilitates and broadens the scope of its applicatory usage.
