  • Patent number: 7765921
    Abstract: A press cage bar for a device for expressing liquids, which is bounded by at least one pressing edge in the area of a wear surface of a hard layer and which, in the area of at least one lateral face of the body of the cage bar, has at least one spacer that is raised above the lateral face. The spacer is formed as a deposit weld on the lateral face of the cage bar and is provided with a certain bottom clearance from the underside of the cage bar, which is on the opposite side of the cage bar from the wear surface. The spacer extends along the lateral face no farther than to the hard layer. The extent of the spacer transversely to a longitudinal axis of the lateral face is greater than its extent in the direction of the longitudinal axis of the lateral face. The spacer has increasing thickness perpendicular to the lateral face in a direction extending from the hard layer towards the underside of the cage bar.

  • Patent number: 7763339
    Abstract: 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.

  • Patent number: 7753377
    Abstract: 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.

  • Patent number: 7726625
    Abstract: A transfer device for transferring an actuator displacement, has a housing with a first recess having a first and second plunger displaceably mounted. These plungers are actively connected via at least one transfer chamber by a fluid. The active connection causes the second plunger to be displaced when the first plunger is moved and vice versa. The transfer chamber is hydraulically coupled via a sealing gap to a compensating chamber compensating the pressure differences, in a delayed manner. The transfer device also has a chamber device with a compensating chamber, a chamber housing, and a first plunger. The chamber device has a device with a first body with a recess including a second body, and with an elastomer placed in the recess between the first and second body.
