Patent number: 8834153Abstract: In a flame arrester arrangement having a housing (1) for holding at least two flame arrester inserts (6, 6?) having a large number of axial passage gaps dimensioned for a combustible gas, and having an intermediate layer (7) arranged between two flame arrester inserts (6, 6?), which permits a radial distribution of the gas flow emerging from one flame arrester insert (6, 6?) and entering an adjacent downstream flame arrester insert (6, 6?), the ability of the flame arrester inserts (6, 6?) to be easily assembled and disassembled for servicing purposes without restricting the functional integrity can be achieved by at least one separate closed seal (11, 11?, 15, 17, 17?, 20) being arranged between a flame arrester insert (6, 6?) and the housing (1) or between two flame arrester inserts (6, 6?) in such a way that a flow around the flame arrester insert (6, 6?) in a space (12) located radially outside the passage gaps is prevented.Type: GrantFiled: June 4, 2010Date of Patent: September 16, 2014Assignee: Protego (U.S.A.), Inc.Inventors: Frank Helmsen, Christoph Leinemann

Patent number: 8092213Abstract: In a flame arrester insert comprising two metal strips (1, 2) wound together, of which a first metal strip (1) is a smooth strip and the second metal strip (2) is a grooved strip having defined grooving, so that they rest on each other at defined contact points (3) and, between the contact points (3), form defined gaps (4) for the passage of a fluid, the stability can be increased and corrosion prevention can be implemented even with inexpensive materials by the metal strips (1, 2) resting directly on each other at the contact points (3) and, outside the contact points (3), having a surface coating (5) which, close to the contact points, is a uniform joint coating of the surfaces of the metal strips (1, 2) that point toward each other.Type: GrantFiled: May 30, 2007Date of Patent: January 10, 2012Assignee: Leinemann GmbH & Co. KGInventor: Christoph Leinemann

Patent number: 7959434Abstract: In a flame arrester arrangement which is formed from two metal strips (8, 9) which are wound together to form a disk having an approximately circular outer circumference and of which a first metal strip (8) is a smooth strip and the second metal strip (9) is a corrugated strip having defined corrugation, the two strips (8, 9), by bearing against one another, forming defined gaps (11) for passage of a fluid and being held in position, relative to one another by fixing pins inserted into radial bores (6), the radial bores (6) can be incorporated without deforming the gaps (11) even in the region of the bores (6) by virtue of the fact that the bores (6) are incorporated by spark erosion without deforming the corrugation formed in the second metal strip, such that the gaps (11) are also present in the region of the bores (6) in the manner defined by the corrugation.Type: GrantFiled: December 10, 2009Date of Patent: June 14, 2011Assignee: Leinemann GmbH & Co.

Patent number: 7918664Abstract: A permanently fireproof flame guard includes a flow area (2) which terminates a conduit and within which an inserted flame shield is disposed. The flame shield is provided with a plurality of passage gaps that ensure permanent fire safety. Cooling of the permanently fireproof flame guard can be improved by forming at least one concentric, annular section (5) within the flow area (2) in a massive manner without passage gaps while forming annular sections (4) comprising passage gaps around the concentric, annular section (5).Type: GrantFiled: June 3, 2004Date of Patent: April 5, 2011Assignee: Leinemann GmbH & Co.

Patent number: 6409779Abstract: A method for rendering a detonation front harmless. The method includes a pipe extending into a housing and proximate to the flame arresting device. The detonation front is conveyed directly to a portion of the flame-arresting device. The detonation front is expanded in front of the arresting device so as to create a deflagration, which then impinges on the outer cross-section of the flame arresting device.Type: GrantFiled: January 10, 2001Date of Patent: June 25, 2002Assignee: Leinemann GmbH & Co.Inventor: Christoph Leinemann

Patent number: 6342082Abstract: A detonation safety device having a flame-arresting device positioned in a housing. A pipe extends into the housing and proximate to the flame arresting device. In order to render a detonation front traveling in a pipe harmless, the detonation front is conveyed near the flame-arresting device. The flame-arresting device includes a diameter larger than the pipe and the detonation front such that the detonation front impinges only on a partial surface of the flame-arresting device. The detonation front is expanded in front of the arresting device so as to create a deflagration, which then impinges on the outer cross-section of the flame arresting device.Type: GrantFiled: April 23, 1999Date of Patent: January 29, 2002Assignee: Leinemann GmbH & Co.Inventor: Christoph Leinemann
