Abstract: The invention relates to a flat seal such as those that are used in motor vehicle construction in particular. Such flat seals can be used for example as seals in the exhaust tract of internal combustion engines, as cylinder head gaskets, or also as hydraulic system control plates. Hydraulic system control plates, such as transmission control plates for example, always have a sealing function in addition to a fluid control function simultaneously.

Abstract: The invention relates to a lock for a door, comprising a catch and a pawl. The catch can be in an open or closed position. The catch may be brought into holding engagement with a lock striker. The pawl may be brought into an engagement position. The pawl may be deflected into a release position, to release the catch. A pawl actuation lever can deflect the pawl into the release position. A switchable coupling arrangement is provided between the pawl actuation lever and the pawl. The switchable coupling arrangement may be brought into a closing and an opening state. When the actuation movement of the pawl actuation lever surpasses a threshold, an inertial characteristic of the lock causes the switchable coupling arrangement to switch into the opening state such that the pawl actuation lever runs without deflecting the pawl into its release state.

The coating may include a thickness between 5 ?m and 150 ?m and a hardness between 1000HV and 3500HV.

Abstract: A seal structure has one metal gasket arranged between a pair of casings. The metal gasket is provided with a planate outer peripheral portion and a bead portion which is formed by rising up from an inner peripheral end portion of the outer peripheral portion, and is arranged so that the bead portion comes into contact with the one casing, and the outer peripheral portion comes into contact with the other casing. The bead portion elastically deforms so as to reduce its height and the outer peripheral portion elastically deforms on the basis of the elastic deformation of the bead portion, when the metal gasket is pinched by the pair of casings, and a leading end of the outer peripheral portion comes into contact with one casing at this time, whereby any gap in which salt water stays is not formed between one casing and the metal gasket.

Abstract: This is directed to a hook and receiving element combination for securing components forming the shell of an electronic device. The receiving element can include a beam connected to the outer shell component and operative to deflect as the hook element approaches the receiving element. To limit deflections of the outer shell component, the beam can be restrained at opposing ends in directions perpendicular to the beam length, but free to slide along the beam axis. In some embodiments, the receiving element can include a lip for guiding the deflection of the beam as the beam contacts the hook element. In particular, the lip can ensure that the beam deflects at an angle relative to the hook element motion such that a smaller hook element motion is required to engage the beam.

A radial seal portion of the body defines a radial seal between the first and second components. A lip seal portion of the body defines a lip seal between the first and second components. The first and second component can be a housing and a cover of a vehicle fob.

Abstract: A seal ring is disclosed. The seal ring can have one or more exterior surfaces extending between a first outer axial end of the seal ring to a seal flange. The seal flange can be positioned adjacent to a second outer axial end of the seal ring and can extend radially outward to an outer diameter of the seal ring. An outer surface of the seal flange can form an annular sealing band. A seal ramp can extend outwardly from a first end proximate to the first outer axial end of the seal ring to a second end positioned adjacent to the seal flange. The seal ramp can include a first surface configured to form a frictional, sealing contact interface between the first surface and an elastomeric seal compressed into contact with the first surface when the elastomeric seal is in a loaded state.

Abstract: A gasket for placement between a base of an aircraft structure and the underside of a workpiece, such as an aircraft antenna, is disclosed. The gasket has a cured polyurethane elastomeric gel body with a multiplicity of holes therethrough. The body typically has a flat lower surface and upstanding side walls, but the top surface is non-flat. The top surface may have sloped areas or raised tabular areas or a combination. The gel body may also have a skeleton member, such as a flexible metallic screen or other woven member. When the gasket is placed between the aircraft, base and the workpiece, threaded on fasteners, and the fasteners torqued down, the non-flat upper surface will flow such that, at proper torque setting, it fully coats and fully covers the underside of the workpiece and, typically, makes contact with the screen or skeleton member, which also makes contact with the upper surface of the base.

Abstract: A system and method is provided for setting a metal-to-metal seal (e.g., in an annular space between wellhead components) using a temporary elastomer seal. For example, the annular space may be sealed with one or more elastomer seals before hydraulically setting the metal-to-metal seal. A seal assembly may include the elastomer seals and the metal-to-metal seal. Positioning the seal assembly in the annular space between the wellhead components may isolate pressure in the annular space below the seal such that the metal-to-metal seal may be set. In an exemplary embodiment, a hydraulic mechanism axially compresses the metal-to-metal seal between two members of the seal assembly, thereby radially expanding and setting the metal-to-metal seal.

The pliable body includes a first portion having a first firmness and a second perimeter portion have a firmer consistency. When such a composite body is placed under compression, the perimeter will tend to limit the flow of the softer inner material past the firmer perimeter region or portion of the gasket. In this manner, creep or overrun of the less firm portion material will be reduced.
