Patent number: 6408536Abstract: The present invention relates to a process for drying protein crystals starting from an aqueous protein crystal suspension, which comprises drying the protein crystal suspension in a centrifugal dryer, where the protein crystals, after they have been filtered off from the protein crystal suspension, are brought into contact with a drying medium which consists of a mixture of water and a nonaqueous solvent which is miscible with water in any ratio and which has a lower vapor pressure than water. In the process, a drying gas which has been moistened with water is advantageously used. The protein crystal suspension is advantageously converted into a fluidized bed for the purpose of drying.Type: GrantFiled: January 13, 2000Date of Patent: June 25, 2002Assignee: Aventis Pharma Deutschland GmbHInventors: Rolf Deusser, Peter Kraemer, Horst Thurow

Patent number: 5667641Abstract: The invention overcomes the problem of paper edge overdrying during the paper drying process on paper machine drying cylinders. It comprises applying a thin ceramic coating onto the circumferential exterior surface of the cylinder near the cylinder edges, thereby forming a thermal barrier coating which decreases paper drying rate at said edges and reduces or eliminates paper edge overdrying.Type: GrantFiled: October 23, 1995Date of Patent: September 16, 1997Assignees: Pulp and Paper Research Institute of Canada, Pyrogenesis Inc.Inventors: Nicole A. Poirier, Peter G. Tsantrizos

Patent number: 5319862Abstract: A method of and an apparatus for drying/curing a dry material such as a mat of fibrous or powder material as may be used for building purpose as well as a non-dry material such as a thermosetting resin are disclosed. The disclosure relates to the sealing function during the drying/curing step. The apparatus comprises a heating and blowing mechanism for drying/curing a mat as it is being conveyed by a conveyor mechanism including pair of upper and lower conveyors, and shield mechanism for shielding between the conveyor mechanism and the heating and blowing mechanism. The shield mechanism includes wire brushes on blowing boxes of the heating and blowing mechanism for abutment against caterpillar plates of forward runs of respective conveyors to seal between the caterpillar plates of the forward runs and the blowing boxes.Type: GrantFiled: March 22, 1993Date of Patent: June 14, 1994Assignee: Sanei-Kisetsu Co., Ltd.Inventor: Katsuyuki Ohgihara
