Patent number: 6858666Abstract: A method forms self-sustaining particles that comprise a hydrophobic (oleophilic) phase in particulate form, with no need for a rigid shell to encapsulate the phase, and usually with no shell present. The oleophilic phase contains a gelation agent, and preferably an organogelation agent. The particles may be stored alone or in a minor amount (e.g., less than 40% by volume) of water to assist their stability and act as a barrier against their coalescence. These water-separated compositions are not necessarily dispersions or suspensions, but may be merely particles in an aqueous storage environment. The particles have prolonged stability and can be readily, simply, and inexpensively formed. A simple method of manufacture comprises forming a solution of the ingredients (e.g., at least the oleophilic material and gelation agent) at a temperature above their gelation temperature, forming droplets or molten, or liquid or flowable particles of the solutions, and cooling the droplets to form the particulates.Type: GrantFiled: March 4, 2002Date of Patent: February 22, 2005Assignee: Aveka, Inc.Inventors: Monica A.

Patent number: 6139613Abstract: The present invention describes a novel method for the formation of optically variant pigments by the coating of layers onto a substrate and the fracturing of the coated material into pigment particles after the coating operation and novel pigments produced thereby. Coating techniques such as slot die coating (especially multiple slot die coating), spin coating, meniscus coating, curtain coating, and the like have proven successful. It is preferred that multiple die slots are used to coat multiple layers in a single pass so that manufacturing costs are minimized. The use of these coating techniques, and especially multiple die slot coating, allows for many layers to be coated, with from three to fifty layers being readily possible. This offers a relatively inexpensive way of coating out a wide variety of layers, and especially the pigment materials needed for optically variable pigments, quickly and with high quality.Type: GrantFiled: August 21, 1998Date of Patent: October 31, 2000Assignee: Aveka, Inc.Inventors: William A.

Patent number: 6071981Abstract: A polymer composition comprising an anticoagulant carried in a water soluble polymer hydrogen bonded to a cellulose polymer. The composition is useful as sutures, implantable material, temporary grafts, vasculature connections and the like. The composition can be prepared by a method comprising the steps of: forming a solution in an amine oxide of a water-soluble polymer capable of hydrogen bonding, a cellulose polymer, and an anticoagulant and reducing the amount of amine oxide in the solution to solidify a solid polymer composition comprising the anticoagulant in the water soluble polymer and the cellulose polymer. The polymer compositions are particularly useful in temporary implants, sutures, grafts or the like.Type: GrantFiled: September 30, 1998Date of Patent: June 6, 2000Assignees: Aveka, Inc., Techmatch, Inc.Inventors: Dee Lynn Johnson, William A.

Patent number: 6045650Abstract: A process is described for applying a solid coating onto a surface of an article. The surface of an article has a first physical property measurable as a degree of hydrophobicity and/or hydrophilicity. A liquid coating of an oxidizable material containing at least one element other than carbon, hydrogen, oxygen and nitrogen is applied onto the surface of the article. The oxidizable material is oxidized on the surface to attach an oxidized material having said at least one element other than carbon, oxygen, nitrogen and hydrogen onto said surface. This process thereby changes the first physical property with respect to its hydrophobicity and/or hydrophilicity. The process is relatively gentle to the underlying surface, at least in part because of the moderate temperatures which may be used for oxidation, and a wide range of properties may be provided onto the surface by appropriate selection and/or mixing of the liquid material and selection of the surface.Type: GrantFiled: September 16, 1997Date of Patent: April 4, 2000Assignee: Sunsmart, Inc.Inventors: Mark A. Mitchnick, Garry Gwozdz, William A. Hendrickson
