Abstract
The reeling system is contained within a buoy towed by a submerged submarine. The reeling system includes a pressure sealed housing, a cable reel disposed for rotation within the housing and a buoyant cable antenna disposed in an ejecting and retracting relationship with the reel. One end of the cable antenna extends from the housing to the exterior of the buoy. A cylinder-piston arrangement having a sea water inlet and a connection to the housing is responsive to the pressure of the sea water at the inlet to control air pressure in the housing to provide a pressure difference between the air pressure in the housing and the pressure of the sea water on the one end of the cable antenna exterior of the buoy for ejection and retraction of the cable antenna from and into the buoy.

A buoyant cable antenna reeling system for a buoy towed by a submerged submarine comprising:
- a pressure sealed housing contained within said buoy;
- a cable reel disposed for rotation within said housing;
- a buoyant cable antenna disposed in an ejecting and retracting relationship with said reel, said cable antenna having one end thereof extending from said housing to the exterior of said buoy;
- and
- a cylinder-piston arrangement having a sea water inlet and a connection to said housing, said arrangement being responsive to the pressure of said sea water at said inlet to control air pressure in said housing to provide a pressure difference between said air pressure in said housing and the pressure of said sea water on said one end of said cable antenna exterior of said buoy for ejection and retraction of said cable antenna from and into said buoy.
