Patent number: 7763339Abstract: A three-dimensionally structured fiber fabric has a high fluid absorption capacity of at least 5 g fluid per g of fiber fabric and elevations and depressions that occur alternately and regularly with reference to the fabric plane, which includes at least one nonwoven fabric layer and a shrunk fabric bonded to it. The bond between the nonwoven fabric layer and the shrunk fabric has been produced by hot bonding, and the hot bonding occurred at least perpendicular to the direction of the greatest shrinkage of the shrunk fabric, in the form of regularly arranged lines. Furthermore, spaces have formed between the nonwoven fabric layer and the shrunk fabric, at the alternately occurring elevations and depressions, which spaces promote the fluid absorption capacity of the fabric. These fabrics may be used as wiping cloths, wet wipes, as fluid dispensers for cleaning or for applying fluids, etc.Type: GrantFiled: July 8, 2002Date of Patent: July 27, 2010Assignee: Carl Freudenberg KGInventors: Dieter Groitzsch, Oliver Staudenmayer

Patent number: 7753377Abstract: A shaft seal includes an elastomeric annular body having a radially inwardly protruding annular lip. An annular outer case receives the elastomeric annular body. An annular inner case is embedded into the elastomeric annular body. An annular insert is positioned adjacent the inner case. A backup/support insert is received in a recessed pocket in the elastomeric body and outboard of an axially extending annular bead protruding from the body and compressed sealingly against the radially inward extending leg of the seals annular outer case. The backup/support insert and axially extending annular bead act to prevent sealed fluid pressure from acting against a rind portion of the elastomeric body thus leaving outwardly extending beads of the rind portion free to compress or decompress to accommodate eccentric deflection of the shaft. The outer case, the insert, the backup insert and the inner case support the lip and compensate for shaft offset.Type: GrantFiled: January 29, 2007Date of Patent: July 13, 2010Assignee: Freudenberg-NOK General PartnershipInventor: Robert P.
