<3ENERAL SYSTEM DESCRIPTION 



The aystertit shown diagrammatical ly in Figure 1^ consists 

 of a nvimber of lengths of three-quarter-inch-diaraeter cable 

 coupled by pipe-like housings. Provision is made for instru- 

 mentation in the central sections of the housings ^ with cable 

 terminals and appropriate electrical fittings in the end pieces 



The cable is covered with a free-swiveling^ hydrodynamic 

 fairing to reduce drag and vibration; the instrument modules 

 are also faired. A core-space, to accommodate any suitable 

 electrical cable, is available within the load-carrying cable 

 armor. 



The cable-fairing-module assembly is retained at proper 

 depth by a depressor, which develops the requisite depressing 

 force by a combination of weight and hydrodynamic reaction. 



Shipboard handling is accomplished by an endless-track- 

 type winch for systems with rigid instrument modules distri- 

 buted along the faired cable^ or by a twin-load-drum winch for 

 systems lacking modules. 



The faired cable is delivered to the stowage area under 

 a low tension^, permitting storage in multiple layers on a 

 drum or in a well. 



For convenience J the elements of the system have been 

 grouped as follows:
