Abstract: The present disclosure is directed toward systems, methods, and non-transitory computer-readable media for generating and providing a hybrid search-and-browse interface for accurately and efficiently locating and presenting targeted genealogical content items. For example, the disclosed systems generate and provide a multi-layered navigational structure using browse trees that represent categories of genealogical content items, where each successive browse tree in the hybrid search-and-browse interface narrows the search results from the one before based on some (selected) criteria. In some cases, to support a hybrid search-and-browse interface, the hybrid search-and-browse system generates and maintains a facet index for genealogical content items stored in a database as a basis for generating and providing browse trees for navigating through search results of content items.

Abstract: An intake manifold for a multicylinder internal combustion engine includes a number of inlet runners operatively connected with a mounting flange. A sealing region circumscribes only an outer periphery of the mounting flange and does not extend between adjacent ones of the intake runners. The sealing region includes a continuous groove formed in the mounting flange and a sealing composition applied to the groove.

Abstract: A hydraulically operated charge air system for an internal combustion engine includes an intake manifold having a number of intake runners, and a number of rotatable airflow control devices mounted within at least a portion of the intake runners. A hydraulic motor rotatably positions the airflow control devices.

Abstract: Systems and methods for selectively activating and deactivating gas exchange valves in a variable displacement internal combustion engine include a rocker arm having a positioning device that opposes movement of a lash adjustment device while deactivated to position a coupling hole of the rocker arm within a desired coupling range to facilitate coupling of the rocker arm during subsequent activation of an associated engine cylinder.

Abstract: A poppet valve operating system for an internal combustion engine includes poppet valves which are driven by rocker arms rotationally mounted to a rocker shaft. Each of the rocker arms is maintained in axial alignment upon the rocker shaft by a separate, resiliently biased telescoping pin housed in the rocker arm body. The rocker arm pins extend into indexing reliefs formed in the outer cylindrical surface of the rocker shaft.
