A lid controlling apparatus includes a casing having a target region, a lid, and a rod driving mechanism connected between the casing and the lid. The rod driving mechanism includes a first rod pivoted to the casing, a non-rotatable gear fixed to the casing, a driven gear pivoted to a side of the first rod and connected to the lid, and a planetary gear device pivoted to the side of the first rod and engaged with the non-rotatable gear and the driven gear for rotating between lifting and closed positions. When the planetary gear device rotates to the lifting position, the first rod pivots with rotation of the planetary gear device to have a first included angle relative to the casing, and the planetary gear device rotates the driven gear to make the lid have a second included angle relative to the first rod for exposing the target region.

A chair adjusting device includes a control pull-bar including an elongate plate assembly formed of multiple elongate plates and a short plate assembly formed of multiple short plates. The elongate plates have a movement hole and a pivot hole opposite to the movement hole, and connecting protrusions at one side the pivot hole and connecting dimples on a back side of the connecting protrusions. Separator plates are interposed between the elongate plates and have combination projections receivable into the connecting dimples and combination notches on a back side and receiving the connecting protrusions therein. The short plates have engaging projections at one side thereof, and engaging troughs on a back side. Partition plates are interposed between every two pieces of the short plates. The partition plates have fitting bulges receivable into the engaging troughs and on a back side and receiving the engaging projections therein.

Control system (1) comprising a control rod (5) extending between a first zone (2) situated in a hydraulic chamber delimited by a chamber wall (3) and a second zone (4) situated outside the hydraulic chamber. The control system (1) further comprising a seal (6) arranged around and against this control rod (5) to oppose the passage of fluid between the first and second zones (2, 4). The system further comprises a guide piece (7) assembled removably with respect to the chamber wall (3), the seal (6) is assembled inside the guide piece (7) so as to allow relative movement of the rod (5) with respect to the guide piece (7) while at the same time achieving sealing between the first and second zones (2, 4).

A parking lock pre-selection mechanism for a work machine is disclosed in which a pawl is engageable with teeth on a power train output shaft to lock it in place. An operator lever is used to preselect the parking lock position. The mechanism includes first and second pivotally interconnected links, urged by a spring to a maximum length set by a stop. The spring causes the pawl to be urged into place when the teeth and pawl are in proper alignment.

The present invention is an Electric servo system which controls and automates gate openings based on GPS speed and position data that results in precise and reliable modern variable and constant rate application. The Electric servo system also allows for Mechanical gate linkages to remain intact, resulting in few changes to the aircraft and redundancy of emergency components. A Mechanical input connect/disconnect is used to effortlessly transfer between the automated Electric servo system and the Mechanical gate system.
