Patent number: 10787368Abstract: Provided are processes for the formation of electrochemically active materials such as lithiated transition metal oxides that solve prior issues with throughput and calcination. The processes include forming precursor materials into agglomerates prior to calcination. The use of the agglomerates improves gas flow into and out of the materials thereby improving calcination results, electrochemical properties of the resulting materials, and allows for use of high temperature kilns not previously suitable for such materials thereby lowering production costs.Type: GrantFiled: June 6, 2018Date of Patent: September 29, 2020Assignee: BASF CorporationInventors: William C. Mays, Diana F. Wong, Xue Liu, Benjamin Reichman, Martin Panchula, Gary Yacobian

Patent number: 9919948Abstract: A high silica glass composition comprising about 92 to about 99.9999 wt. % SiO2 and from about 0.0001 to about 8 wt. % of at least one dopant selected from Al2O3, CeO2, TiO2, La2O3, Y2O3, Nd2O3, other rare earth oxides, and mixtures of two or more thereof. The glass composition has a working point temperature ranging from 600 to 2,000° C. These compositions exhibit stability similar to pure fused quartz, but have a moderate working temperature to enable cost effective fabrication of pharmaceutical packages. The glass is particularly useful as a packaging material for pharmaceutical applications, such as, for example pre-filled syringes, ampoules and vials.Type: GrantFiled: June 8, 2016Date of Patent: March 20, 2018Assignee: MOMENTIVE PERFORMANCE MATERIALS, INC.Inventors: Kipyung Ahn, Guangjun Xu, Martin Panchula, Samuel Conzone, Tianjun Rong, Konstantin S.

Patent number: 9249028Abstract: The present invention is directed to a method of making metal oxide and mixed metal oxide particles. The method includes treating a mixture formed from a metal source, such as metal alkoxide, a surfactant, and a first alcohol in an aqueous media at a very high metal oxide yield. The mixture is reacted using a catalyst to form metal oxide particles having a desired particle size in said mixture. By washing the particles with an aprotic solvent, the residual carbon content of the particles can be significantly reduced. The method is particularly suitable for forming silica particles. The metal oxide particles can then be heat treated to form synthetic fused metal oxides such as, for example, synthetic fused silica.Type: GrantFiled: July 27, 2012Date of Patent: February 2, 2016Assignee: MOMENTIVE PERFORMANCE MATERIALS INC.Inventors: Antonio L. DeVera, Martin Panchula

Patent number: 8877662Abstract: The invention relates to a silica glass compound having improved physical and chemical properties. In one embodiment, the present invention relates to a silica glass having a desirable brittleness in combination with a desirable density while still yielding a glass composition having a desired hardness and desired strength relative to other glasses. In another embodiment, the present invention relates to a silica glass composition that contains at least about 85 mole percent silicon dioxide and up to about 15 mole percent of one or more dopants selected from F, B, N, Al, Ge, one or more alkali metals (e.g., Li, Na, K, etc.), one or more alkaline earth metals (e.g., Mg, Ca, Sr, Ba, etc.), one or more transition metals (e.g., Ti, Zn, Y, Zr, Hf, etc.), one or more lanthanides (e.g., Ce, etc.), or combinations of any two or more thereof.Type: GrantFiled: July 2, 2012Date of Patent: November 4, 2014Assignee: Momentive Performance Materials, Inc.Inventors: Nathan J. Cassingham, Ben Matthew Gauthier, Martin Panchula, Robert Stephen Pavlik, Yan Zhou, Konstantin S. Zuyev

Publication number: 20070255251Abstract: A transdermal drug delivery system with a high barrier retainer for holding a microprojection member for disrupting a body surface to an individual. The retainer is made of a high barrier material (such as metal) that is easily sterilizable, such as by heat, and can be used for keeping out contamination and maintaining the environment of the microprojection member.Type: ApplicationFiled: March 9, 2007Publication date: November 1, 2007Applicant: ALZA CORPORATIONInventors: Martin Panchula, Ling-Kang Tong

Publication number: 20050124941Abstract: Cartridges are provided for storing and facilitating the delivery of pharmaceutical formulations. In one preferred embodiment, the cartridge comprises a body including a bore extending through the body, and a plunger movably disposed in the bore. The bore has a transverse dimension at a distal end that is equivalent to that at a midpoint. The plunger has a planar contact surface that is transversely coextensive with the bore for applying a force to a pharmaceutical formulation contained in the bore. This configuration helps to eliminate dead volume, and therefore enables filing by volume rather than weight to ensure accurate dosing.Type: ApplicationFiled: November 12, 2004Publication date: June 9, 2005Inventors: Martin Panchula, Stan Lam, Pete McArthur, Scott Lautenbach

Patent number: 5100406Abstract: A liner for a breast pump which results in increased milk pumped from the female breast having a bell-shaped, flexible body which flares outwardly at one end to a size sufficient to fit over the female breast and narrows at the opposite end to an opening of a size sufficient to permit the flow of milk and which is provided with a circular extension to be connected to the pumping head. The body is provided on its outer surface with recesses providing a membranous wall portion thinner than the body.Type: GrantFiled: November 1, 1990Date of Patent: March 31, 1992Assignee: Graham-Field, Inc.Inventor: Martin Panchula
