The vapor is condensed on the condensing surface to create a condensate which is removed from the condensing surface. Removal is performed, using more than gravity, without allowing non-uniformities of the condensate film to occur. The magnetic particles are oriented on the coated substrate by subjecting the coated substrate to a magnetic field created at a location outside of the dryer space.Type: GrantFiled: July 7, 1997Date of Patent: September 29, 1998Assignee: Minnesota Mining and Manufacturing CompanyInventors: John D.

Patent number: 5694701Abstract: A method and apparatus of drying a substrate uses a condensing surface located adjacent the substrate on the side of the substrate being dried. The liquid from the substrate is evaporated and then condensed on the condensing surface without applied convection. The condensed liquid is removed from the condensing surface while the condensed liquid remains liquid. Evaporation can be performed by heating the substrate without applied convection.Type: GrantFiled: September 4, 1996Date of Patent: December 9, 1997Assignee: Minnesota Mining and Manufacturing CompanyInventors: Gary L. Huelsman, William B. Kolb

Patent number: 5581905Abstract: A method and apparatus of drying a substrate uses a condensing surface located within 15 cm of the substrate on the side of the substrate being dried. The liquid from the substrate is evaporated and then condensed on the condensing surface without applied convection. The condensed liquid is removed from the condensing surface while the condensed liquid remains liquid. Evaporation can be performed by heating the substrate without applied convection.Type: GrantFiled: September 18, 1995Date of Patent: December 10, 1996Assignee: Minnesota Mining and Manufacturing CompanyInventors: Gary L.

Patent number: 5522157Abstract: Stacks (16) of sheet material are moved on a conveyor (12, 14) between air manifolds (18, 20) and guide pins (19, 21); so that, drying gas is directed between the sheets of the stacks to cause the stacks to expand to form fluffed stacks 28 through which air moves readily to dry the sheets. A compression roller (26) is used to expel air from the fluffed stack and return the stack essentially to its original height. A reduction in tendency to curl is achieved in low relative humidity environments for sheets of photographic film.Type: GrantFiled: October 11, 1994Date of Patent: June 4, 1996Assignee: Eastman Kodak CompanyInventors: Michael A. Howey, Eric M. Leonard, Michael Long, James A. White

Patent number: RE38412Abstract: Drying a coated substrate which includes magnetic particles includes a condensing surface spaced from the substrate. This creates a longitudinal gap between the substrate and the condensing surface. Liquid is evaporated from the substrate to create a vapor and the vapor is transported to the condensing surface without requiring applied convection. The vapor is condensed on the condensing surface to create a condensate which is removed from the condensing surface. Removal is performed, using more than gravity, without allowing non-uniformities of the condensate film to occur. The magnetic particles are oriented on the coated substrate by subjecting the coated substrate to a magnetic field created at a location outside of the dryer space.Type: GrantFiled: September 29, 2000Date of Patent: February 3, 2004Assignee: Imation Corp.Inventors: John D.
