Abstract: A system including a plurality of servers mounted in server racks and a cold aisle containment (CAC), the CAC including a roof system, wherein the roof system includes a frame, a plurality of roof panels, wherein each roof panel is connected to the frame and is rotatable with respect to the frame, and a holding mechanism for holding a first roof panel among the plurality of roof panels in a closed position, wherein each roof panel among the plurality of roof panels overlaps at least one adjacent roof panel among the plurality of roof panels, and wherein release of the holding mechanism causes each of the roof panels to rotate to an open position in a cascading manner.

Abstract: This invention provides a canopy, including a skeleton and at least one electric roller blind mechanism. Two sides of the electric roller blind mechanism have one guide rail, respectively, the guide rails are disposed at the skeleton, the electric roller blind mechanism includes a cloth drooping member capable of moving up and down, and two ends of the cloth drooping member slidably cooperate with corresponding two guide rails, respectively. In this invention, by providing the guide rails cooperating with the electric roller blind mechanism at the skeleton, the cloth drooping member can move up and down along the guide rails, such that the roller blind of the canopy can be opened or closed as needed, which is convenient compared to manual operation.

Abstract: An automatic double angle motorized roof system that is applicable to restaurants, arbores, buildings, and so forth, which can be opened and can be installed to roofs. It can be used in all roof applications.

Abstract: There is provided a ceiling panel for a pod room. The ceiling panel comprises one or more cover components movable between an open configuration and a closed configuration; and an actuation mechanism configured to move the one or more cover components from the closed configuration to the open configuration in response to a trigger. The ceiling panel may provide a specified percentage open area in the open configuration. The ceiling panel may be adapted to acoustically insulate the pod room in the closed configuration.

Abstract: A positioning element permits the panel or engine bonnet of a motor vehicle to be brought from the closed position into a position in which a gap forms between the upper edge of the opening and the lower edge of the panel. The panel can thus easily be unlocked and fully opened. The positioning element with inner lever and outer lever is connected to a drive component, which via the drive element and the drive pawl with a detent ensures that the panel is brought in a simple manner via the levers into the first raised position, for which purpose the detent is pushed into the recess of the outer lever and thus brings the outer lever and the inner lever into the first raised position. Once the panel has been brought by spring loading into the second raised position with the aid of the spring-loaded inner lever, the upward travel is completed, so that by means of the spring force associated with the outer lever, said outer lever then quickly pivots both levers back into the initial position.

Abstract: The present disclosure relates to a sliding door arrangement with an attenuation and retraction device facilitating soft-closing of a sliding door. The arrangement includes an attenuation and retraction device, which may be placed in the extension of a rail guiding and retaining the door, and a pin that extends from the door and interacts with the attenuation and retraction device. The pin may optionally be locked in a retracted position during mounting of the door in order to protect the pin from damage resulting from excessive side forces.

Abstract: A first movable barrier operator is actuated in order to move a first movable barrier to a first predetermined position via a first movement and according to a first operating characteristic. A second operating characteristic is selected for moving a second movable barrier to a second predetermined position via a second movement. The second operating characteristic is chosen so that the second movement of the second movable barrier to the second predetermined position does not interfere with the first movement of the first movable barrier to the first predetermined position. A second movable barrier operator is actuated to move the second movable barrier to the second predetermined position via the second movement according to the second operating characteristic.

Abstract: A catcher member is provided to be movable between a standby position and a retracted position, and at the standby position, while being urged by an urging device, the catcher member is positioned in the standby position by a holding device. When a movable body is moved forward a predetermined movement position, a striker member is caught and engaged with the catcher member positioned in the standby position, and subsequently, holding by the holding device is released, and the catcher member is moved or relatively moved up to the retracted position by being urged by the urging device, so that the urging force is applied to the movable body up to position where the movement ends. An operation device is provided so as to be able to operate to move the catcher member which was moved to the retracted position without catching the striker member, toward the standby position.

Abstract: A movable wall has a plurality of movable wall elements mounted in horizontally oriented guide rails. The guide rail which defines the path of the movable wall elements from the parked position into the closed position is laid out in a 90 degree curve in the vicinity of a room opening to be closed so that it brings the closed movable wall elements into alignment. The final movable wall element in the direction of the closing motion is mounted on support and guidance elements. At least the rear support and guidance element of the final wall element in the direction of the closing motion, is mounted on the final movable wall element so that the rear support and guidance element can be moved along the final movable wall element. This rear support and guidance element also has its own drive unit, by which drive unit, during the closing process, the final movable wall element is automatically moved into the closed position in which it is flush with the other movable wall elements.

Abstract: An opening and closing type louver device comprising a louver in which a number of blades are arranged in a row in a required spaced relation on rotating shafts within a frame. Each blade is opened and closed by a driving mechanism while maintaining their parallel relation.
