Publication number: 20040045407Abstract: An appliance for sharpening razor blades of the type held in a blade cartridge comprises a leather strop bonded onto a magnetic substrate that is in turn bonded onto a support. The width of the strop does not exceed the width of the blades in typical cartridges, so that the blades may rest on the strop when the cartridge is stroked over the strop to hone the blade edges. The surface of the strop is proud of the support surface adjacent the strop, to ensure that edges of the cartridge that are typically proud of the blades do not prevent contact of the blades with the strop. The ends of the strop are secured in undercut formations in the holder.Type: ApplicationFiled: September 11, 2002Publication date: March 11, 2004Inventor: Roy Martin Katz

Patent number: 5955109Abstract: Retinoic acid compositions intended for topical application are incorporated in novel formulations in which they are retained as impregnants inside the pores of porous solid particles or microspheres. The pores form a continuous network open to the exterior of the particles, permitting outward diffusion of the retinoic acid impregnant at a controlled rate depending on the pore size. The impregnated particles are prepared by impregnation of preformed particles with the retinoic acid.Type: GrantFiled: June 17, 1993Date of Patent: September 21, 1999Assignee: Advanced Polymer Systems, Inc.Inventors: Richard Won, Martin A.

Patent number: 5871722Abstract: Ionic compositions comprise an active ingredient absorbed within a network of internal pores defined by a plurality of polymeric particles. The particles are preferably crosslinked polymeric beads having a diameter in the range from about 5 to 100 microns and a surface charge density from about 0.1 to 10 meq/qm hydrogen ion capacity. The active ingredients are released from the ionic polymer beads over time when orally administered, applied to a keratinic material, typically human skin or hair or otherwise delivered to a target environment. The use of a cationic charge promotes adhesion of the beads to the keratinic material.Type: GrantFiled: April 11, 1995Date of Patent: February 16, 1999Assignee: Advanced Polymer Systems, Inc.Inventors: Sergio Nacht, Richard Won, Martin A.

Patent number: 5726068Abstract: A diffusive sampler for effectively determining chemical vapor levels, the ampler having a thin pouch-like container made up of an impermeable back sheet and a selectively permeable front membrane attached thereto along its peripheral edges. The front membrane is made of a material capable of passing preselected vapors therethrough and for preventing other preselected vapors from passing therethrough and preferably has substantially the same permeation rate as human skin. Located within the pouch-like container is an adsorbent substance for adsorbing the chemical vapor and for providing information with respect to the chemical vapor levels adsorbed thereby. In use a plurality of the samplers are adhered to the skin of an individual wearing a protective garment to establish the effectiveness of the garment when subjected to specific chemical vapors.Type: GrantFiled: January 24, 1996Date of Patent: March 10, 1998Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Donald Rivin, Cyrus E.

Patent number: 5458890Abstract: Flavored food and pharmaceutical compositions include one or more flavor additives incorporated within polymeric particles, usually within an internal pore network defined by individual polymeric particles. The polymeric particles are, in turn, dispersed within and/or over a surface of an orally-deliverable matrix material, which is usually a solid or semi-solid substrate. In the case of chewable compositions, the flavor additives will be released into the orally-deliverable matrix material as the composition is chewed and held in the mouth, thus prolonging the flavor of the composition. In the case of dried powders and mixes, the flavor will typically be made available as the product is consumed or be released into the matrix material as the composition is further processed. When two flavors are combined with the polymeric particles, the relative amounts of the additives can be selected to provide simultaneous release and exhaustion of the additives.Type: GrantFiled: June 4, 1991Date of Patent: October 17, 1995Assignee: Advanced Polymer Systems, Inc.Inventors: John H. Williford, Martin Katz, Sergio Nacht, Chung-Heng Cheng, Rajesh A. Patel, Brian J. Picard
