摘要:
An aerial camera system including a plurality of main reels, a camera interface/safety reel and a stabilized camera head. The camera head is supported from main cables from the main reels with a safety reel cable providing power, data and video communication between the camera head and a main computer system. Each of the main reels, the camera interface/safety reel and the camera head are in communication with the main computer system, which controls the feeding and reeling in of the main cables. Further, the computer system controls the feeding and reeling in of the safety reel cable, which typically only follows the camera head as it moves in three-dimensional space, but may in emergency mode support the weight of the camera head and be used to slowly pull the camera head up and out of the way so that it does not interfere with any activity below the flight area. The aerial camera system may also include a level wind assembly that keeps the cables wound on the drum of the main reels and/or the safety reel in a controlled and consistent manner. Furthermore, the camera head of the aerial camera system may use a rotating gimbal assembly with computer controlled leveling motors for keeping the camera head level as the gimbal assembly moves.

摘要:
A method of improving the mechanical properties of a .gamma./.gamma.'-.alpha. eutectic nickel-base superalloy body containing a .gamma.-phase, a .gamma.'-phase, and an aligned molybdenum fiber .alpha.-phase which comprises the steps (a) heating the body to a temperature at which at least a portion of the .gamma.'-phase will transform to a .gamma.-phase, (b) maintaining the heated body at said temperature to allow transformation of at least a portion of said .gamma.'-phase to a .gamma.-phase, and (c) cooling the transformed body to a temperature at which at least a portion of the .gamma.-phase precipitates as a modified .gamma.'-phase.
摘要:
A method of forging Ni-base superalloys is described which avoids the growth of abnormally large grains in the surface region of a forged article. The method involves forging and/or annealing a Ni-base superalloy in a carburizing environment. Forging and/or annealing in a carburizing environment is done to maintain the carbon concentration in the surface region at a level that is sufficient to prevent the depletion of carbides and carbonitrides. The carburizing environment may also be selected so that it is non-oxidizing with respect to aluminum, in order to prevent the depletion of aluminum and the reduction of the .gamma.' phase in the surface region.
