Patent number: 6953594Abstract: The present invention provides a novel process for producing a calcium phosphate cement or filler which hardens in a temperature dependent fashion in association with an endothermic reaction. In the reaction a limited amount of water is mixed with dry calcium phosphate precursors to produce a hydrated precursor paste. Hardening of the paste occurs rapidly at body temperature and is accompanied by the conversion of one or more of the reactants to poorly crystalline apatitic calcium phosphate. The hardened cements, fillers, growth matrices, orthopedic and delivery devices of the invention are rapidly resorbable and stimulate hard tissue growth and healing. A composite material is provided including a strongly bioresorbable, poorly crystalline apatitic calcium phosphate composite and a supplementary material. The supplementary material is in intimate contact with the hydroxyapatite material in an amount effective to impart a selected characteristic to the composite.Type: GrantFiled: November 23, 2001Date of Patent: October 11, 2005Assignee: Etex CorporationInventors: Dosuk D.

The hollow fibers may be inorganic or organic and of any desired length, wall thickness or cross-sectional configuration. The modifying agent is selected from materials capable of beneficially modifying the matrix fiber composite after curing. The modifying agents are selectively released into the surrounding matrix in use in response to a predetermined stimulus be it internal or externally applied. The hollow fibers may be closed off or even coated to provide a way to keep the modifying agent in the fibers until the appropriate time for selective release occurs.Type: GrantFiled: July 17, 2001Date of Patent: March 4, 2003Inventor: Carolyn M.

Patent number: 6525111Abstract: Paint compositions and coatings having improved overall visual appearance, richness or depth of color and aesthetic properties such as for spraying-painting automobiles, boats, aircraft and home appliances. The present paint compositions are high solids content, heat-curable, transparent or translucent compositions containing embedded light-refractive colorless and/or tinted transparent glass beads preferably between about 10 to 20 microns diameter, and one or more color-enhancing agents such as pigments, dyes, aluminum flakes, mica, opaque glass beads, holographic flakes, and similar conventional light-enhancing agents. The present bead-containing refractive paint compositions may be based upon volatile organic solvents, water or may be solvent-free powder compositions, but in all cases the resinous binder material is cross-linkable at the baking temperature of the paint, or upon exposure to ultraviolet radiation, to cure as a hard, translucent, chip-resistant paint.Type: GrantFiled: October 30, 2000Date of Patent: February 25, 2003Assignee: Prizmalite Industries Inc.Inventors: Andrew B. Spencer, John W. Andrews, Gary D. Tucker, II
