Publication number: 20150373989Abstract: Compositions having antimicrobial activity contain surface functionalized particles comprising an inorganic copper salt which has low water solubility. These types of inorganic salts may also be introduced in porous particles to yield antimicrobial compositions. The compositions may optionally comprise additional antimicrobial agents, salts with high water solubility, organic acids, salts of organic acids and their esters. The compositions may be added to various fluids used in the petroleum extraction industry, or used as coatings on components used in this industry. These antimicrobial materials may be used for reducing both anaerobic and aerobic bacteria and are also useful for reducing corrosion of ferrous components caused by anaerobic bacteria. Although such compositions may be used for any antimicrobial application, and some of the other important uses of these compositions are in wound care, personal care and waste processing.Type: ApplicationFiled: September 2, 2015Publication date: December 31, 2015Applicant: AGIENIC, INC.Inventors: Nicholas R. Krasnow, Anoop Agrawal, Donald R. Uhlmann, John P. Cronin, Murat Akarsu, Ryan J. Reeser, Lori L. Adams

Patent number: 5384294Abstract: Method is provided for preparing PbO-based ceramics by mixing metal cations in alkanolamines and then adding the mixture to lead carboxylates in alcohol, to obtain ceramic solutions or gels therefrom. The metal cations are sourced from metal alkoxides, chelates and salts and include metals of Ti, Zr and La. The above solutions and gels can be employed to form PbO-based powders, fibers and films, e.g. films of PZT and PLZT, which find electrical and optical applications such as ferroelectric memory and dielectric waveguides. The invention resides in the above method and resulting PbO ceramics which have e.g. films of considerably higher dielectric constants than previously known in the art.Type: GrantFiled: November 30, 1993Date of Patent: January 24, 1995Assignee: The United States of America as represented by the Secretary of the Air ForceInventors: Gimtong Teowee, Jonathan M.

Patent number: 5103537Abstract: A strap fastener assembly which comprises a flat rigid plate-like member and a flexible strap. The plate-like member has an opening extending therethrough in the form of two elongated slots which intersect with each other to form an acute angle. One of the slots is wider than the other. The strap has a thickened portion which prevents it from being pulled through the slot of lesser width but on movement of the strap to the other slot, its thickened portion can be pulled through that other slot.Type: GrantFiled: February 7, 1991Date of Patent: April 14, 1992Assignee: Pet Affairs Inc.Inventors: William A. Snyder, Mark L. Angier, Anthony C. Mulligan, Donald R. Uhlmann
