Patent number: 7537935Abstract: A process and closure arrangement is provided for isolating purified biological material. The process includes placing biological materials in separate lysis vessels, adding lysis liquids to the biological materials in the lysis vessels, and transferring the liquids in the lysis vessels into a matrix unit. The liquids in the matrix vessels of the matrix unit are extracted through outlet openings during which the liquids flow through matrices and the matrix unit is placed on a collecting unit with collecting vessels which are arranged such that at least the outlet openings of the matrix vessels extend into the collecting vessels. The matrix vessels are with elution fluid and elution fluids from the matrix vessels are extracted through their outlet openings during which the elution fluids flow through the matrices and the elution fluids which are enriched with biological material are collected in the collecting vessels.Type: GrantFiled: October 27, 2003Date of Patent: May 26, 2009Assignee: Roche Molecular Systems, Inc.Inventors: Gerhard Bienhaus, Michael Fritz, Jurgen Schwab, Thomas Walter

Patent number: 6669910Abstract: System and process for isolating purified biological materials with a collecting unit which has collecting vessels that are accessible from above with a matrix unit in which matrix vessels are arranged in a holder as well as a closure unit which can be placed on the collecting unit to close the collecting vessel. In addition the invention also concerns a system having a collecting unit, a matrix unit, and a closure unit as well as a lysis unit and a waste unit. Moreover a new closure arrangement is disclosed which is suitable for closing vessels in which there is excess pressure.Type: GrantFiled: October 2, 2000Date of Patent: December 30, 2003Assignee: Roche Diagnostics GmbHInventors: Gerhard Bienhaus, Michael Fritz, Jurgen Schwab, Thomas Walter

Patent number: 6619248Abstract: A device (1) for hydraulic rotational angle adjustment of a camshaft relative to a crankshaft of an internal combustion engine including a drive unit (4) connected with the crankshaft and an output unit (5) non-rotatably connected with the camshaft. The drive unit (4) stands in power transmitting connection with the output unit (5) through at least two pressure chambers (6, 7) formed inside the device (1) which bring about, under action by pressure under continuous compensation for external pressure leakages, a relative rotation or a hydraulic clamping of the output unit (5) in relation to the drive unit (4). In addition, the device (1) has a coil spring (8) arranged outside the device which is provided for adaptation of its adjustment speeds in both adjustment directions.Type: GrantFiled: July 12, 2002Date of Patent: September 16, 2003Assignee: INA-Schaeffler KGInventors: Thomas Bertelshofer, Gerd Wiessner, Jurgen Schwab, Thomas Kleiber

Patent number: 6258531Abstract: A method of isolating a biological material by a) providing a biological material which is bound to a porous matrix (C11), and b) compressing the matrix under conditions where the biological material is released from the surface of the matrix into an elution liquid. brings about the advantage that the emission of aerosols into the environment is greatly reduced. It is also possible to obtain highly concentrated and minute amounts of solution. The method is also easy to automate.Type: GrantFiled: March 26, 1996Date of Patent: July 10, 2001Assignee: Roche Diagnostics GmbHInventors: Gerhard Bienhaus, Michael Fritz, Jürgen Schwab, Edda Geisler, Herbert Harttig, Heinz Macho

Patent number: 6024138Abstract: Dispensing device for dispensing small quantities of fluid comprising a compressible balloon with an end-to-end capillary inserted within the walls of the balloon in such a way that the one end of the capillary communicates with the interior of the balloon and the other end of the capillary communicates with the exterior space. The balloon has at least one opening through which the interior space of the balloon communicates with the exterior space. The at least one opening has a flow resistance that is designed so that a fluid contained in the capillary is expelled when the balloon is compressed. The present invention also comprises a system and method for the metered dispensing of fluids.Type: GrantFiled: April 17, 1998Date of Patent: February 15, 2000Assignee: Roche Diagnostics GmbHInventors: Michael Fritz, Heinz Macho, Helmut Rinkel, Jurgen Schwab, Georg Arras, Klaus Oswald, Alfred Schaffner

Patent number: 6024235Abstract: The invention relates to a container seal with a sealing body which can be punctured for supplying or removing liquids to or from a container (3) by means of a blunt hollow needle (10), this sealing body consisting at least partially of a highly elastic material in which a cut is made at the puncture point (23) through at least 75% of its thickness. The seal can in this case be designed independently in the form of a stopper or as a small insert plate for a seal.Type: GrantFiled: November 21, 1994Date of Patent: February 15, 2000Assignee: Dade Behring Marburg GmbHInventor: Jurgen Schwab

Patent number: 6017698Abstract: Subject matter of the invention is a method of binding a biological material to a solid phase by providing a sample liquid containing the biological material in a sample vessel (A) having an inner contour (A17); then a hollow body (C) which has a contour (C12) that matches the inner contour (A17) is introduced into the sample vessel (A) while being closed with respect to the sample vessel by means of a porous matrix (C11); the sample liquid can enter the structural form (C) through the porous matrix (C11). This method is easy to automate and reduces the generation of aerosols.Type: GrantFiled: April 1, 1996Date of Patent: January 25, 2000Assignee: Roche Diagnostics GmbHInventors: Gerhard Bienhaus, Michael Fritz, Jurgen Schwab, Edda Geisler, Herbert Harttig, Heinz Macho

Patent number: 5957822Abstract: A lid for closing an opening of a vessel includes a lid body configured to engage the opening, with the vessel having a defined shape. The lid body includes an engagement part which engages a corresponding surface of the vessel, thereby closing the opening. A handling element is disposed on an outer portion of the lid, with the handling element extending in parallel with an axis of the vessel. The handling element is for handling the lid for opening and closing the vessel.Type: GrantFiled: April 1, 1996Date of Patent: September 28, 1999Assignee: Boehringer Mannheim GmbHInventors: Gerhard Bienhaus, Michael Fritz, Jurgen Schwab, Edda Geisler, Herbert Harttig, Heinz Macho

Patent number: 5855852Abstract: A vessel for reducing contamination of liquids is formed of a vessel body with an inlet opening and an outlet opening therein. A closing device is attached to the vessel body adjacent the outlet opening. The closing device closes the outlet opening, and includes a normally closed one-way valve which is openable by a predetermined pressure from within the vessel body.Type: GrantFiled: March 29, 1996Date of Patent: January 5, 1999Assignee: Boehringer Mannheim GmbHInventors: Gerhard Bienhaus, Michael Fritz, Jurgen Schwab, Edda Geisler, Herbert Harttig, Heinz Macho
