摘要： This invention relates to an apparatus for transferring a cryogenic fluid from one dewar to another and is characterized in that it provides a means for equalizing the temperatures in the liquid and vapor spaces of the supply dewar whereby the pressure in the dewar may be utilized for accurate control, either manual or automatic, of the amount of heat that must be added to the cryogenic liquid supplied to the receiving dewar for obtaining the desired receiving dewar pressure with minimum addition of heat to the supply dewar and no loss of cryogenic fluid through overboard vents during the transferring process. The apparatus has particular application as a ground servicing unit for filling liquid nitrogen dewars in aircraft.

摘要： A high-place observation device for stably performing a fixed-point observation of a target object from a high place is provided. The high-place observation device provides [Solution] Provides a long pole which is formed to extend and contract freely and which stands on the installation surface, a rotorcraft for positioning the pole to a desirable height position by extending and contracting the pole by a floating force in a connected state, a winding mechanism which fixes and maintains the height position of the pole to the height position set by the rotorcraft, and a camera attached to the rotorcraft.

摘要： The technology provides a launch rig structure capable of filling a very large balloon envelope while the balloon is arranged vertically. The filled balloon is capable of staying aloft in the stratosphere with its payload for months or longer. The launch rig structure is configured to rotate up to 360° in response to current wind conditions. It includes an integrated lifting boom and gas handling system to fill the envelope. A payload release assembly is configured to couple with a rigid connection member of the balloon, enabling the envelope to be filled while in a vertical orientation. The payload release assembly is part of a launch cart that is positioned within the interior space of the launch rig. A gripper assembly engages with the rigid connection member. Once the envelope is filled, the gripper assembly disengages from the connection member so that the balloon floats away from the launch rig.

摘要： The present disclosure relates to an anchoring platform for captive aircraft that addresses one of the main problems when handling captive aerostats, which is the excessive workload required to switch between flying and anchored states. The technology disclosed herein requires only one person to install the structure and the operation can be performed remotely or by a person. Additionally, cords, together with the confluence point, are wound into the anchoring device, the winch. The structure for anchoring the captive aircraft is the cradle which bears the aerostat, while the winch exerts tension to hold same static in the structure.
