Abstract: A filter assembly that includes a filter housing with a housing interlocking feature, a filter cover with a filter cover interlocking feature, and a filter element with a filter element interlocking feature is disclosed. The filter element is positionable within the filter housing, and the filter cover is attachable to a top portion of at least one of the filter element and the filter housing. The housing interlocking feature, the filter cover interlocking feature, and the filter element interlocking feature are interlockable with each other and extend in a nonplanar configuration along at least one side of the filter element when the filter housing, the filter cover, and the filter element are assembled together.

Abstract: A latch assembly for a compartment of a vehicle interior is provided. The latch assembly comprises a frame, a first pawl member, a second pawl member, a lever member, and a resilient member. The frame has a first portion, a second portion, and a third portion. The frame is fixed to a cover of the compartment. The first pawl member is slidingly disposed in the first portion of the frame. The second pawl member is slidingly disposed in the second portion of the frame. The lever member has a first and a second pivot pin and a center hub. The center hub is rotatably supported by the third portion of the frame. The first pivot pin is disposed in the first pivot slot of the first pawl member. The second pivot pin is disposed in the second pivot slot of the second pawl member.

Abstract: A controlled equilibrium device comprising a housing; at least one spring, each at least one spring having a spring stiffness; and a load leveling device movable through the housing between a first maximum displacement position and a second maximum displacement position, the load leveling device comprising a deadband displacement zone defined between a first deadband displacement threshold and a second deadband displacement threshold, the displacement required to reach the first and second deadband displacement thresholds being less than the displacement distances required to reach the first and second maximum displacement positions, the at least one spring stiffness being substantially constant when the displacement of the load leveling device is within the deadband zone, the stiffness of the at least one spring being modified to a second stiffness when the load leveling device is equal to or beyond either the first deadband displacement threshold or the second deadband displacement threshold.

Abstract: A door closer, for controlling the movement of a door as the door is opened and closed, the door closer comprising: an input member movable in response to movement of the door, the input member being movable in a first direction and in a second direction; return means for moving the input member in the second direction; and damping means for controlling the movement of the input member in the second direction, the damping means comprising: a rubbing member movable in the first and second directions, and a body for engagement by said rubbing member to produce a surface effect damping force in at least one of the first or second directions.

Abstract: Elastomer dampers (20) and (120) for damping movement between two relatively moveable members, such as shimmy motion between components in an aircraft landing gear assembly (10). Each damper includes a housing (24) having an internal cavity (36) with a cylindrical interior surface (34) and an opening (41), and a member assembly (28, 128) moveable relative to the housing (24) having an elongated shaft (30) received through the opening (41) with a piston head assembly (32) mounted thereon. The piston head assembly (32, 132) has a annular support element (46, 146) received over the shaft (30) with a sleeve-like elastomer member (48, 148) received over it. The elastomer member (48, 148) engages the interior surface (34) in an interference fit relationship thereby radially precompressing the elastomer element (48, 148) in the range of between about 5% and 15%.

Abstract: A mount assembly is provided for mounting a component, such as an engine, to a vehicle for active control of vibration. The assembly includes first and second mounting members and, an intermediate insert with first and second elastomeric systems connecting said first and second mounting members with the intermediate insert in between. An actuator in parallel with said first elastomeric system provides vertical force to said first elastomeric system to provide a relatively soft vertical rate. A controller operates the actuator in response to sensed vibration so that the vertical force tends to avoid or cancel it. A relatively high fore/aft and lateral dynamic rate of the first system protects the actuator. The second elastomeric system connects the second mounting member with the intermediate insert and exhibits a relatively high vertical rate and a relatively soft fore/aft and lateral rate. One or more sensors feeds data to a controller that analyzes the vibrations to determine the harmonics thereof.
