Abstract: In a fuser roll for electrostatic copying machines comprising a cylindrical metal core surrounded by a cylindrical body of elastomeric material having an outside cylindrical sleeve of protective material, the end surfaces of the elastomeric material are protected from the deleterious effects of silicone fluid by sealing rings of elastomeric material such as fluorosilicone which is resistant thereto. The rings, which are rectangular in cross section and are made of uncured, deformable material, are inserted in the ends of the sleeve with the ends of the sleeve protruding. The sleeve is assembled with the metal core and placed in a cylindrical mold. Silicone rubber is injected into the space between the core and the sleeve and the sleeve and rings are expanded into contact with the mold wall. The roll is then cured. In the finished cured rolls, the rings are bonded to the end surfaces of the silicone rubber body, and to the interior cylindrical surfaces of the sleeve over an area of substantial width.

Abstract: A canvasworking method is disclosed herein which comprises a procedure by which the entire surface of an open weave material is covered. The method entails the formation of several endways-adjacent stitches in a line along the top of the open weave material, and several endways-adjacent stitches in a line along the bottom of the open weave material and directly underlying the top stitches. The top and bottom stitches each extend between first and second holes in the open weave material. The first and second holes of at least two of the top stitches and of the bottom stitches include at least one hole in the open weave material lying therebetween, such that the stitches extend more than just between adjacent holes. The method is preferably performed by first weaving a strand of material through an open weave material in a first direction forming a line of alternately top and bottom stitches.

Abstract: An athletic shoe sole has a heel section and a toe section bearing flange-shaped, turf-gripping members. The first gripping member is a generally downwardly and outwardly extending flange that runs around the entire periphery of the sole. The second gripping member is an ovoid-shaped, generally downwardly and outwardly extending toe flange positioned in the toe section of the sole and spaced inwardly from the portion of the peripheral flange on the toe section. The third gripping member is a heel flange extending downwardly and outwardly from the heel section of the shoe and spaced inwardly from the portion of the peripheral flange on the heel section. The rearward portion of the heel flange is arcuate and merges into two generally forwardly extending flange portions that flare outwardly and join with the peripheral flange adjacent the forward end of the heel section. All of the flanges are downwardly convergent and have a bottom edge.

Abstract: Methods of making feminine hygienic pads from non-layered and layered material by use of folding to make predetermined multiple folds in said material, said folding may be with a device attached to a sewing machine for stitching said pads longitudinally adjacent a longitudinal leading edge creating an anterior narrow leading panel of narrow thickness and a posterior under panel of a wider thickness providing a long geometric form. Thereafter the said long geometric form is multiple cut providing pads of about two inches long. In some pads having fillers, the filler material is laid between the folds of the layered or non-layered material prior to stitching and after the long geometric form is produced, it is cut into desired lengths about two inches long providing the pads. These pads are for insertion into the interlabial space and have a geometric configuration which facilitates insertion of the pad into the interlabial space and has improved retention within such space.

Abstract: Decorative plastic welt has an elongated, decorative, arcuate, bead portion formed of a first plastic material. An integral elongated plastic flange extends from said bead along its length to an outer flange edge and defines a first flange portion adjacent the bead and a second integral flange portion extending from the first portion to the flange edge. The second portion is an elongated see-through plastic strip which permits the flange to be aligned with sheet materials on either side so that positioning notches in the sheet materials can be matched by visual observation through the strip.
