Patent number: 5958398Abstract: The present invention relates to biodegradable biocompatible polyacetals, methods for their preparation, and methods for treating mammals by administration of biodegradable biocompatible polyacetals. A method for forming the biodegradable biocompatible polyacetals combines a glycol-specific oxidizing agent with a polysaccharide to form an aldehyde intermediate which is combined with a reducing agent to form the biodegradable biocompatible polyacetal. The resultant biodegradable biocompatible polyacetals can be chemically modified to incorporate additional hydrophilic moieties. A method for treating mammals includes the administration of the biodegradable biocompatible polyacetal in which biologically active compounds or diagnostic labels can be disposed.Type: GrantFiled: December 7, 1998Date of Patent: September 28, 1999Assignee: The General Hospital CorporationInventor: Mikhail I.

Patent number: 5496858Abstract: Aqueous disinfectant concentrate which includes succinic dialdehyde, glutaraldehyde and/or formaldehyde, one or more alcohols of limited water miscibility and optionally usual auxiliaries. By diluting with water, a working solution can be prepared from the concentrate. The advantages of the new disinfectant concentrate or disinfectant are the reduced development of odor, an improved material compatibility, an improved microbicidal effectiveness and a clearly increased storage-stability. Furthermore, the activation usual up until now with disinfectants based on aldehyde is superfluous. Preferred application fields are surface and instrument disinfection.Type: GrantFiled: January 11, 1994Date of Patent: March 5, 1996Assignee: Reckitt & Colman Inc.Inventors: Heinz Eggensperger, Bernd Lower, Michael Mohr, Peter Goroncy-Bermes, Rolf Kleinwort

Patent number: 5061732Abstract: Based upon the discovery thata porcupine attack of wood structures is due to the presence of sodium in the conventional resin used in the wood structures, the invention provides for replacing the base used in wood processing with potassium hydroxide or ammonium hydroxide or any other non-sodium base. Potassium hydroxide is found to be a specific deterrent to porcupines. A preferred resin formulation contains potassium hydroxide as the base, and an additive of potassium chloride in an amount of from 5% to 20%, and preferably 10%, by weight of the potassium hydroxide. The potassium-containing resin formulation may be used to make potassium-containing wood products, applied as an adhesive for gluing together wood objects accessible outdoors, mixed with a water-insoluble gum or paint or used to make potassium-containing panelling or shingles which are applied to existing wood structures to render them porcupine-proof.Type: GrantFiled: January 22, 1990Date of Patent: October 29, 1991Inventor: Uldis Roze

Patent number: 5004757Abstract: Very potent, stable, ordorless, and phenol-free virciudal solutions are active at high dilution when used for surface decontamination of animate and inanimate objects. The virucidal compositions described are efficacious in a matter of minutes against both the lipophilic and the more resistant hydrophilic viruses. The three active ingredients in these virucidal compositions are the glutaraldehyde monomer in equilibrium with its hydrates and polymers, hydrogen-bonded glycol molecules to eliminate aldehydes odor, and an anionic surfactant of the alkyl sulfate, alkyl sulfonate, alcohol sulfate or alkyl aryl sulfonate type. A preferred anionic surfactant would be the Sodium Dodecyl Sulfate (SDS), which exhibits strong cidal synergism against the Herpes Simplex Virus type 1 when mixed at a concentration as low as 0.0005% in diluted glutaraldehyde aqueous solutions (0.0025%). Improved virucidal killing at higher dilutions of the same formula were observed with the more resistant Coxsackie B viruses.Type: GrantFiled: December 20, 1988Date of Patent: April 2, 1991Assignee: Wave Energy Systems, Inc.Inventor: Raymond M.
