Abstract: A removable adaptor mount for receiving a camera-carrying gimbal beneath an aircraft wing has a base plate with a clamp for removably engaging the diagonal wing strut. An anchor on the base spaced from the strut clamp can be secured to the wing. Holes on the base permit a conventional gimbal to be bolted to the mount.
Abstract: An expander compressor unit for a vapor compression refrigeration system is disclosed. The unit has a rotor which is provided with radial passageways terminating in tangentially oriented nozzles for expanding the high-pressure fluid and utilizing the kinetic energy of the expanding fluid to propel the rotor. The rotor is in driving engagement with a compressor which serves to compress fluid in the cycle. By this means the expander compressor unit substantially improves the efficiency of the cycle through efficient expansion of the refrigerant prior to evaporization and through reduction of the net work input into the system.
