Patent number: 6830727Abstract: The invention relates to a method for stocking and preserving green round wood and sawn timber, which is stored in an airtight and lighttight sealing cover. The oxygen inside the cover is decomposed by the respiratory process of fungi, bacteria and wood cells that are still alive, thereby forming CO2 and H2O. Fermentation processes also lead to the decomposition of hemicelluloses and saccharides which are converted to organic acids and CO2. The oxygen content in the cover is less than 0.1 vol. % after an adjustment time of 3 to 10 days of total stocking, while said CO2 content rises to more than 21 and up to 40 vol. %. This method enables green round wood a swan timber to be stocked over long periods without wastage or environmental damage.Type: GrantFiled: August 23, 1999Date of Patent: December 14, 2004Assignee: Technische Universitaet DresdenInventors: Gerold Mahler, Christoph Richter, Martin Gross, Andreas Weber, Thomas Maier, Juergen Koenig

Patent number: 6814932Abstract: A fluid delivery system (26) for an automated processor (A) delivers washing, microbial decontaminant, and rinse fluids to spray nozzles (102, 104, 106, 108, 110) in a chamber (12) for sequentially spraying the fluids over a lumened device (B), such as an endoscope. Sets of nozzles are operated in sequence to avoid the spray jets canceling each other out. The endoscope is supported on a rack (21) which is agitated by an activation system (330). This ensures ever changing points of contact between the device and the rack so that all external surfaces are contacted by the spray. A computer control system (80) controls cleaning, decontamination, rinsing, and drying stages of a cycle, and agitation of the rack at appropriate times, which are all carried out within the chamber, obviating the need for human contact with the device during processing.Type: GrantFiled: February 7, 2001Date of Patent: November 9, 2004Assignee: Steris Inc.Inventors: James C. Hlebovy, Alan J. Greszler, Nancy A. Robinson
