Abstract: A valve cover includes a first cover portion, second cover portion, web, and a plurality of bolt holes formed therein. The first cover portion has a first shape. The second cover portion has a second shape that is different from the first shape. The web connects the first cover portion to the second cover portion. The valve cover has a long axis disposed along the first cover portion, web and second cover portion. A first bolt hole of the plurality of bolt holes is offset from a remainder of the plurality of the bolt holes.

Abstract: An energy recovery retrofit kit for a hydraulic control system is disclosed. The energy recover retrofit kit may have a first accumulator and a second accumulator. The energy recover retrofit kit may also have a recovery valve block fluidly connectable between an existing pump and an existing motor of the hydraulic system. The recovery valve block may be configured to selectively fluidly communicate the first and second accumulators with the existing motor.

Abstract: Systems and methods for data relationship visualization are disclosed. An exemplary system comprises a processor, database, display, query module, relationship module, and user interface module. The query module may be configured to receive a first query and a second query. The first and second queries may assist in retrieving a first and second query result sets, respectively, from the database. The relationship module may be configured to identify a first subset associated with the first query result set and the second query result set based on at least some of the first query result set and at least some of the second query result set. The user interface may be configured to generate a first node to represent the first query result set, a second node to represent the second query result set, and a first edge between the first node and the second node to represent the first subset.
