Patent number: 7124465Abstract: The present invention is directed to a cleaning sponge. The cleaning sponge contains a cavity that is cut radially inward through one of the sides of the sponge. The cavity is located closer to the side of the sponge rather than its center. Furthermore, the sponge has two holding arms that are formed when the cavity is cut and form a channel, allowing the sponge to be placed on a faucet or any other hanging member. The holding arms pull apart when the sponge is placed on a faucet and once the sponge is on the faucet, they pull together. Since the cavity is near the side of the sponge, the holding arms do not interfere with the cleaning function of the sponge. Furthermore, the sponge has several layers with different coefficients of coarseness for cleaning different surfaces and may be cut in any decorative shape desired.Type: GrantFiled: September 15, 2000Date of Patent: October 24, 2006Assignee: Kaminstein Imports, Inc.Inventor: Bruce Kaminstein

Publication number: 20020100132Abstract: A device for treating surfaces of substrates utilized in electronics manufacturing includes a resilient skin encasing a porous polymeric interior. The resilient skin overlies the exterior surface of the brush, and is typically characterized by a higher density, a smaller pore size, and a lower porosity than the interior material of the brush. The skin may serve to distribute physical stress over a larger area, protecting raised or recessed brush features from abrasion and wear. The porosity of the skin may also influence the movement of liquids through the brush, ensuring the homogenous dispensing of cleaning fluids. The resilient skin may be formed during or subsequent to a brush fabrication process such as molding, extrusion, or milling, and can be accomplished through the application of heat, chemicals, or radiation.Type: ApplicationFiled: January 30, 2001Publication date: August 1, 2002Inventors: Daniel T. McMullen, Kristan G. Bahten, James S. Innes, Vincent J. Catalano

Patent number: 6385817Abstract: A drying sleeve is provided for a handle, such as a sports equipment handle. The drying sleeve has an open end, a closed end and an inner surface that define a cavity. An absorbent material and a containment material cover the majority of the inner surface to permit insertion and drying of the handle. A substantially moisture-proof outer cover covers the sleeve.Type: GrantFiled: February 27, 2001Date of Patent: May 14, 2002Inventor: Ron D. Johnson

Patent number: 6379066Abstract: Disclosed is a cleaning apparatus that is adapted to be worn on the belt of a user. The apparatus permits its wearer to clean a golf ball at any point during a round of golf. The apparatus includes a water tight container with a hinged lid which houses a volume of cleaning fluid. A cleaning implement, such as a sponge, is removably positioned within the container such that it comes into contact with, and absorbs, the cleaning fluid. Thereafter, the implement can be removed from the container and used to clean the surface of a golf ball.Type: GrantFiled: December 21, 2000Date of Patent: April 30, 2002Inventor: David P. Gomez

Patent number: 6326070Abstract: Sawdust particles are freed from their terpene content and thereafter coated with a Teflon wax. The Teflon coated sawdust is hydrophobic and consequently does not absorb water, while the ability to absorb oil is improved. The Teflon coated sawdust is useful in control of oil spills.Type: GrantFiled: March 3, 1999Date of Patent: December 4, 2001Assignee: Virkensdamm ABInventor: Bo Södergren
