Patent number: 8506284Abstract: A method of cooling a load provided in a load compartment in a furnace chamber of a furnace of a hot isostatic pressing device includes releasing hot pressure medium from the load compartment. Cool pressure medium is provided for enabling it to fall through the released hot pressure medium outside the load compartment. The thus obtained mixed pressure medium is led into the load compartment. A hot isostatic pressing device includes a load compartment having an aperture near an upper portion thereof configured to vent warm pressure medium into a region surrounding the compartment and a conduit configured to introduce cool pressure medium into the region surrounding the compartment for mixing with the warm medium. The compartment also includes an aperture near a lower portion thereof configured to receive a mix of warm and cool pressure medium from the region surrounding the compartment.Type: GrantFiled: January 27, 2010Date of Patent: August 13, 2013Assignee: Flow Holdings GmbH (SAGL) Limited Liability CompanyInventor: Carl Bergman

Publication number: 20070292055Abstract: A storage bag for storing items such as food includes a flexible plastic sidewall configured to provide an interior volume, a sealable opening for accessing the interior volume, and a one-way valve element attached to the sidewall and communicating with the interior volume. The opening may be closed and latent air within the storage bag may be evacuated through the valve element. The valve element may also be flexible and its flexibility may be similar to that of the bag itself. In an aspect, the valve element can be a low profile valve element which has a height dimension that is relatively small with respect to the other dimensions of the storage bag and/or valve element. In other aspects, the valve element can have a compact size such that its width, surface area and other similar dimensions are relatively small compared to the other dimensions of the storage bag and/or valve element.Type: ApplicationFiled: August 14, 2007Publication date: December 20, 2007Inventors: Rebecca Reuhs, Robert Dorsey, Michael Borchardt, Carl Bergman

Publication number: 20070116385Abstract: The flexible storage bag includes overlaying first and second sidewalls defining an internal volume that can be accessed from an open top edge. To evacuate air from the internal volume after the open top edge has been closed, the bag includes a one-way valve element attached to the first sidewall and communicating with the internal volume. To prevent the one-way valve element from becoming clogged by the opposing second sidewall, the bag also includes a clearance member that maintains at least a partial clearance between the first and second sidewalls proximate the valve element. The clearance member can take many forms such as a textured portion on the second sidewall that includes evacuation passages which provide air in the internal volume access to the valve element, a permeable element covering the valve element, and a rigid or compressible structure that spaces the second sidewall from the valve element.Type: ApplicationFiled: February 6, 2007Publication date: May 24, 2007Applicant: The Glad Products CompanyInventors: Dean Zimmerman, Carl Bergman, Michael Borchardt

Publication number: 20060157140Abstract: The storage bag includes an interior volume for containing food items and a one-way valve element through which air from the interior volume can be evacuated. To prevent fluids and juices from the stored food items from contaminating the valve element, a separator defining a chamber is included that sealingly connects the valve element to the interior volume. In the separator, fluids and juices separate from the evacuating air by gravitational separation and are returned to the interior volume. In an embodiment, to facilitate packaging and distribution of multiple storage bags, the separator is adjustable between an expanded position for providing the chamber and a collapsed position substantially eliminating the chamber. In an embodiment, the separator may be comprised of elastically expandable material.Type: ApplicationFiled: June 24, 2005Publication date: July 20, 2006Inventors: Carl Bergman, Michael Borchardt, Andrew Neltner

Publication number: 20050215971Abstract: Absorbent articles having a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core disposed between said topsheet and said backsheet are disclosed. The backsheet has a physical variation along at least one axis, wherein said physical variation defines a first backsheet zone and a second backsheet zone, and at least one elastomeric element having at least one primary direction of stretch, said elastomeric element at least partially overlapping and joined to first and/or second backsheet zone, wherein a relaxed pathlength of said elastomeric element in the primary direction of stretch is less than a total pathlength of said backsheet in the region of overlap. The physical variation is a measurable difference as measured by a physical property selected from the group consisting of basis weight, thickness and density.Type: ApplicationFiled: March 29, 2004Publication date: September 29, 2005Inventors: Donald Roe, Pankaj Nigam, Mark Kline, Jeromy Raycheck, Carl Bergman
