Publication number: 20130164362Abstract: A wood preservative includes injectable particles comprising one or more sparingly soluble copper salts. The copper-based particles are sufficiently insoluble so as to not be easily removed by leaching but are sufficiently soluble to exhibit toxicity to primary organisms primarily responsible for the decay of the wood. Exemplary particles contain for example copper hydroxide, basic copper carbonate, copper carbonate, basic copper sulfates including particularly tribasic copper sulfate, basic copper nitrates, copper oxychlorides, copper borates, basic copper borates, and mixtures thereof. The particles typically have a size distribution in which at least 50% of particles have a diameter smaller than 0.25 ?m, 0.2 ?m, or 0.15 ?m. At least about 20% and even more than 75% of the weight of the particles may be composed of the substantially crystalline copper salt. Wood or a wood product may be impregnated with copper-based particles of the invention.Type: ApplicationFiled: April 13, 2012Publication date: June 27, 2013Applicant: Osmose, Inc.Inventors: H.

Patent number: 5908790Abstract: The invention relates to monoclonal antibodies (mAB) which bind to water-soluble complexones such as ethylenediamine tetraacetate (EDTA) or diethylenetriamine pentaacetate (DTPA) with high specificity and avidity and retain their high avidity and specificity for these complexones after complexing of EDTA or DTPA with metal ions. These mAB can therefore be used, e.g. coupled on filters or other supports, for removing toxic heavy metals which are complexed with EDTA or DTPA. Furthermore, these mAB are suitable as components of immunoassays (RIA, ELISA etc.) for the quantitative determination of EDTA or DTPA in aqueous solutions.Type: GrantFiled: June 5, 1995Date of Patent: June 1, 1999Assignee: Behring Diagnostics GmbHInventors: Klaus Bosslet, Peter Hermentin, Gerhard Seemann

Patent number: 5662913Abstract: Antimicrobial metal-based compositions, which are photostable, non-staining, and which are easily absorbed into lipophilic matrices, contain silver cations, complexed by acyclic polyether polymers through the formation of a "host-guest relationship" where the acyclic polyether is the "host" and the silver cation is the "guest," wherein stabilization of this "host-guest relationship" is accomplished through the use of excess anions. The compositions are useful for topical treatment of infections caused by bacteria, fungus and viruses in humans and animals and for treating medical devices, foams and adhesives to impart infection-resistance.Type: GrantFiled: July 1, 1994Date of Patent: September 2, 1997Inventor: Christopher C.

Patent number: 5213803Abstract: A method utilizing compositions for topical application which are adapted for the prevention and treatment of viral infections such as Herpes, AIDS and other envelope virus infections are disclosed. The compositions of the present invention produce a synergistic anti-viral effect when used in combination. The formulation contains a humectant such as sorbitol, glycerol, or other comparable compound in the range of 20-80% w/v final concentration, which facilitates structural and/or functional three dimensional disruption or disorientation of the viral envelope. The activation of the destruction of the envelope and subsequent death of the envelope virus is then achieved using combination of inorganic monovalent anions, nonionic detergents and anionic detergents. These monovalent anions can include sodium bicarbonate, sodium thiocyanate, sodium fluoride and sodium chloride at about 0.5 to 5% w/v final concentration; nonionic detergents such as Tween 20 at concentrations of about 0.Type: GrantFiled: February 24, 1992Date of Patent: May 25, 1993Assignee: Northeastern Ohio Universities College of MedicineInventors: Jerry J.
