Publication number: 20130337183Abstract: A novel Aromatic Thermosetting Copolyester (ATSP) can be processed into highly effective wear resistant coatings by blending with polytetrafluorethylene (PTFE) and other additives. Surface treatments/coatings are key to improving wear performance and durability in a wide array of applications. The problems associated with use of liquid lubricants, hard/soft coatings are well known but only modest progress has been achieved due to lack of research on new material systems. These coatings were fabricated and tested as highly effective wear resistant coatings by blending ATSP with PTFE and other tribologically beneficial additives. The main advantages of these polymeric-based coatings are their relatively low cost and simple substrate surface conditioning (i.e., no need for expensive surface preparation before coating).Type: ApplicationFiled: June 6, 2013Publication date: December 19, 2013Inventors: James Economy, Andreas A.

Patent number: 8609198Abstract: A method for producing a pharmaceutical dose form includes depositing a measured quantity of a first coating material on an external surface of the dose form in a patterned configuration. A measured quantity of a second coating material is deposited on the surface of the dose form in a patterned configuration in relationship to the first coating material. The first and second coating materials form a coating layer in overlying relationship with at least a portion of the external surface of the dose form.Type: GrantFiled: July 21, 2004Date of Patent: December 17, 2013Assignee: Hewlett-Packard Development Company, L.P.Inventors: Iddys D. Figueroa, Enrique C. Abreu

Patent number: 8597729Abstract: In a method and system for forming microbeads, a polymer solution includes particles and a polymer dissolved in a solvent. A stream of the polymer solution flows into a chamber. A focusing fluid contacts and focuses the polymer stream in the chamber. The focusing fluid and the focused polymer stream flow, as a single flow stream, out from the chamber. Pendant droplets detach from a leading end of the single flow stream to form the microbeads. The focusing fluid reacts with the polymer solution to form functional groups at a surface of the microbeads for binding with biorecognition molecules. In the system, a flow focusing apparatus includes a flow focusing body shaped to define the chamber. Microbeads formed according to the methods and systems are also disclosed.Type: GrantFiled: June 23, 2008Date of Patent: December 3, 2013Assignee: FIO CorporationInventors: Sebastien Fournier-Bidoz, Warren Che Wor Chan

Method of coating a porous substrate with a thermoplastic material from the outside of the substrate
Patent number: 8586138Abstract: A method of coating a first porous substrate with a thermoplastic material comprises the steps of: rotating the substrate about an axis of the substrate; and applying the material in a liquefied state onto the substrate, wherein the step of applying is performed from the outside of the substrate. According to another embodiment, a method of coating a porous substrate with a thermoplastic material comprises the steps of: connecting a first porous substrate to a rotator; rotating the substrate about an axis of the substrate; pumping the material in a liquefied state from a receptacle to an application head; and applying the material in a liquefied state onto the substrate, wherein the step of applying is performed from the outside of the substrate. In certain embodiments, the material coated on the substrate is used to help remove at least a portion of a filtercake.Type: GrantFiled: January 19, 2011Date of Patent: November 19, 2013Assignee: Halliburton Energy Services, Inc.Inventors: Luke W.
