摘要： A door operating mechanism for operating longitudinal doors of a railroad hopper car. The mechanism includes operating members that are coupled to ends of the doors. These operating members are each actuated by a separate actuating device that is coupled to a top surface of a sill of the hopper car. Door supports have one end coupled to a door and an opposite end coupled for rotation to an actuating device. When a power cylinder coupled to the operating member is activated, the actuating devices are rotated. This rotation causes the door supports to shift in opposite directions and to open the longitudinal doors.

摘要： The present invention provides a system for automatic operation of a top hatch cover for a container, comprising a hatch cover, a cylinder mount, a main operating lever, a connecting link, and a hatch locking lever. The cylinder mount is configured for pivotally connecting a piston to the container. A lower portion of the main operating lever is connected to a cylinder rod of an air cylinder. A first extension of the connecting link is rotatably connected to an upper portion of the main operating lever and a second extension of the connecting link is coupled to the hatch cover. The main operating lever and the hatch locking lever are rotatably coupled to a main shaft mount, where the hatch locking lever is configured to pivot around the main shaft mount to move between a locked position and an unlocked position.

摘要： A door arrangement, for use on an aircraft, includes a door and an actuation arrangement. The arrangement is configured to move the door between an open position and a closed position. The actuation arrangement includes: a first member coupled to the door such that movement of the first member moves the door; a second member pivotally coupled to the first member and arranged to drive movement of the first member, wherein the second member is movable between a first position which corresponds to the door being in an open position and a second position which corresponds to the door being in a closed position; and an actuator arranged to rotate the second member between the first position and second positions. The door arrangement further comprises a fixed stop.

摘要： A ramp door closure apparatus is provided for recreational vehicles, having a recessed linear actuator both draw a cable from a mounting bracket on the ramp door adjacent to the RV opening, to raise and lower the ramp door, and then cam a locking pin fixed to the ramp door into a seal tight position after the ramp door is raised. Upon release of the locking pin from the cam when opening the door, an initial push is provided to facilitate downward rotation of the ramp door. The linear actuator is selectively detachable from the cable so as to allow manual raising and lowering of the ramp door from within the RV, by means of releasable pins accessed in the mounting structure.

摘要： It is described herein a venting apparatus for an opening in a roof. The venting apparatus for an opening in a roof may comprise a structural frame, an adapter, a mount, a hinge, and a latch. The adapter may comprise a frame adapter section, a lip extending inwardly from a portion of the frame adapter section inner surface, and a protrusion extending upwardly from the lip. The frame adapter section may be configured to fit around an outer surface of the structural frame while the mount may be configured to fit around an outer surface of the protrusion. The latch may be configured to receive a signal from a device when the device detects the presence of smoke within the building to cause the latch to change from a latch closed position to a latch opened position.

摘要： A railcar system that includes a railcar with a discharge opening and a longitudinal gate positioned adjacent to the discharge opening. The system further includes a driving system connected to the longitudinal gate that is configured to move the longitudinal gate between a closed position and an open position. The system further includes a controller connected to the driving system that causes the driving system to position the longitudinal gate in the closed position, position the longitudinal gate in the open position, and position the longitudinal gate to remain an at least partially open position. The longitudinal gate is less than fully open when the longitudinal gate is in the at least partially open position.

摘要： A motor vehicle door includes a door handle unit fixed on the inside on the door edge opposite a door hinge. The door handle unit is motorically pivotable between a folded-in and a folded-out position. In the folded-in position when the vehicle door is closed the door handle unit is arranged behind the vehicle door. In the folded-out position, the door handle unit protrudes laterally outwards by surrounding the door edge and is grippable to open the door. A door mover unit is configured to move the vehicle door in a closed state out of a closed position into a stand-by position, in which the door handle unit can be moved from the folded-in position into the folded-out position. A control unit has a signal input which, upon obtaining the opening signal, controls the door mover unit to move into the stand-by position and controls the door handle unit to pivot into the folded-out position.

摘要： Described and illustrated is a regulating valve for a door drive, wherein the regulating valve has an axis of rotation, wherein the regulating valve includes at least two ends and at least two sealing sections, wherein the regulating valve includes a regulating section, and the regulating section is disposed between the sealing sections. A regulating valve for a door drive, which is particularly simply manufacturable, is realized in that at least one radial thickening forms at least one of the sealing sections, wherein at least one radial tapering of the regulating valve forms the regulating section.
