Disclosed is a hopper car gate assembly including a frame configured for attachment to a hopper car body. The frame defines an opening and includes a beam, wherein the beam has a slot formed therein. A stop plate is removably attached to the beam to selectively obstruct the slot. The assembly has a door supported by the frame. A stop block is attached to the door, wherein the stop block is located on the door such that when the door is inserted into the frame the stop block is aligned with the slot. With the stop plate attached to the beam, the stop block engages with the stop plate to define an open position and prevent further movement of the door in the open direction. With the stop plate detached from the beam, the stop block passes through the slot to allow removal of the door from the frame.

Disclosed is a sliding window emergency opening system, comprising: an emergency opening device (2) and a general opening control device (3); wherein a first rotary shaft (202) in the emergency opening device is rotatably mounted on a first base (201); a first pulling cable (206) is wound around the first rotary shaft (202), and one end thereof is connected with a movable sash of the sliding window (1); a first ratchet (203) is fixedly connected with the first rotary shaft (202); a first elastic component is compressed to make a first pawl (204) abut against the first ratchet (203); a second rotary shaft (302) in the general opening control device (3) is rotatably mounted on a second base (301); one end of a general control pulling cable (303) is connected with the second rotary shaft (302), and the other end is connected with the first pawl (204); when the second rotary shaft (302) rotates, the general control pulling cable (303) is wound up to make the first pawl (204) detached from the first ratchet (203); under the action of the gravity of the movable sash in the sliding window, the first pulling cable (206) drives the first rotary shaft (202) to rotate so as to open the movable sash. In practical application, the general opening control device (3) may be provided at a location far from the emergency opening device (2), and the emergency opening device may be remotely controlled to open the movable sash.

A door control system for a farm implement with a storage bin having a discharge opening and a door movable by a drive mechanism between open and closed positions relative to the discharge opening includes a dual position door control system. The system includes at least two controllers at spaced positions relative to the door and coupled to a drive mechanism for opening and closing the door.

A vehicle door including: an upright pillar sash extending in elevating/lowering directions of the window glass along one of front and rear edges of window glass; and an elevating/lowering mechanism that operates elevating/lowering movement of the window glass by a driving force of a drive source. The upright pillar sash includes: a design part on a vehicle exterior side; and a main body on vehicle interior side relative to the design part, the elevating/lowering mechanism includes: a slider secured to the glass; a guide rail that guides the slider to move in the elevating/lowering directions; and a transmission member that transmits the driving force from the drive source to the slider, the main body of the upright pillar sash houses the slider, guide rail, and transmission member, and the guide rail regulates movement of the slider in both vehicle interior/exterior directions, on a vehicle interior surface side of the glass.

A driving mechanism for sliding a windowed frame guided by an outer frame. The sliding frame is attached to two vertical racks which engage with two pinions. The pinions are connected with a joint axle driven by a couple of engaged bevel gearwheels connected to a crank or to an electric motor. The joint axle with the pinions can be housed in a recess carved at the lower plank of a static window's frame. A compact motorized option in which each pinion is coupled with a gearbox and both gearboxes are driven by a central electric motor also can be housed entirely in the static window's recess. The motorized options also include: a control unit for controlling the direction and speed of the sliding, two limit switches for stopping the frame at highest and lowest positions, an electrical overload sensor which detects sudden sliding obstructions and a burglar alarm.

A mechanism for vertically sliding a windowed frame in one track alongside a static frame installed in a second track. The mechanism consists of two vertical racks installed on the sliding frame, which engage with two pinions coupled with a joint axle which are installed within the lower horizontal plank of the static frame. Turning the joint axle turns also the pinions which move the frame vertically. There are two options for turning the joint axle. The manual option involves turning a crank, the electrical option involves an electric motor coupled with a gearbox. The electrical option also includes a control unit for controlling the direction and speed of the sliding, two limit switches for stopping the frame at highest and lowest positions, an electrical overload sensor which detects sudden sliding obstructions and a burglar alarm. The sliding frame also includes four rollers which reduce the sliding friction.

A vehicle interior component is disclosed. The component may comprise a base and a door moveable along a track between open and closed positions. The door may move in a direction transverse to the track between offset and biased/centered positions. The door may comprise a spring to bias the door toward the biased position. The spring may move first and second arms of the door against the base to prevent door rotation. The door may move along a biased path and first and second offset paths parallel to the biased path. The component may comprise a mechanism configured to move the door from the open position to the closed position along the offset paths and the biased path. The component may comprise at least one of a console, a floor console, a center console, an instrument panel, a door, a cockpit, a storage compartment.
