Patent number: 5230922Abstract: In the bonding of lightweight fleeces, there is the problem at relatively high feeding velocities of providing the fleece with the required amount of impregnating agent. Also, it has been found that the individual fibers of a fleece move with respect to one another during the impregnating step, and the fleece tends to disintegrate. In order to impart to the fleece, without great expenditure, a strength required for the bonding procedure, the provision is made to subject the fleece to a preliminary bonding step by wetting with cold water prior to application of the bonding agent, for example in a foam padder. It has been discovered under practical conditions that this minor bonding step is adequate for avoiding disintegration of the loose fiber layer within the nip padder during impregnation.Type: GrantFiled: December 16, 1991Date of Patent: July 27, 1993Assignee: Fleissner Maschinenfabrik AGInventor: Gerold Fleissner

Patent number: 5049413Abstract: A method for cleaning a leather ball adapted for sport and recreational use is provided. The method includes frictionally contacting the cover of the ball with an abrasive medium sufficient to completely dislodge some of the soil and debris thereon and partially dislodge other soil and debris but insufficient to substantially abrade the cover. The method additionally includes the step of applying a substantially moisture-free particulate material comprising poly tri-sodium phosphate to the cover to completely dislodge any remaining soil and debris following the frictional contacting step. According to one aspect of the method, a conical rotating abrasive surface is oriented relative to a predetermined direction along a seam of the ball and applied to the ball laterally to each side of the seam to frictionally dislodge the soil and debris.Type: GrantFiled: November 1, 1989Date of Patent: September 17, 1991Inventor: William B. Gibson

Patent number: 4979378Abstract: A method of making costume jewelry from cotton burrs, heretofore considered trash, is disclosed. The burrs are first cleaned by removing any residual fibers from between the locks of the burr. Next, the stem is cut close to the crown and the crown is ground to provide a substantially planer surface. Next, the burr is painted, and may also have a coat of lacquer applied. Decorative pellets, ribbon segments and other decorative devices are also secured to and between the locks of the burr. Finally, a wearer attachment device is secured to the planar surface created by the grinding step.Type: GrantFiled: January 12, 1990Date of Patent: December 25, 1990Inventors: Cathy M. Cardin, C. Dwayne Cardin

Patent number: 4800118Abstract: A light stabile composition for imparting stain resistance to polyamide fiber-containing textile articles (e.g. nylon, wool or silk carpets) comprises a halogenated (e.g. brominated or chlorinated) aryl group-containing product of the condensation polymerization of a hydroxyaryl sulfonic acid (e.g., para-hydroxyphenyl sulfonic acid), a dihydroxydiaryl sulfone (e.g., dihydroxydiphenyl sulfone) and an aldehyde (e.g., formaldehyde). The polyamide fiber-containing textile articles are converted to a stain resistant product by containing the fibers with an acidified aqueous solution of the aforesaid composition.Type: GrantFiled: November 4, 1987Date of Patent: January 24, 1989Assignee: West Point PepperellInventors: John W. Reed, Richard D. Smith

Patent number: 4766005Abstract: This invention relates to materials and methods for obtaining strong adhesive bonds of coatings, composites and adhesives to proteinaceous substrates consisting either entirely, or in part of keratin, are disclosed. The invented materials comprise a non-aqueous solvent capable of adjusting the pH of the surface of the substrate to a pH of 8.0 or greater. The invented method comprises treating the substrate with the invented material until the pH of the surface is in the range of pH 9.0 to 11.0, followed by bonding a coating, composite or adhesive thereto.Type: GrantFiled: October 30, 1986Date of Patent: August 23, 1988Assignee: OPI Products, Inc.Inventors: Robert E. Montgomery, George W. Schaeffer
