Development of Line Ranging Equipment.

Equipment has been developed and demonstrated capable of extending and directing a moving loop of line and maintaining it standing essentially horizontally over variable ranges as though it were a rigid structure. Theoretical data were confirmed by tests indicating that line can be deployed and precisely directed with a power requirement of one horsepower per one hundred feet of range at any angle to the vertical. With further development the equipment is expected to be useful where line-throwing guns are now used and in salvage, life-saving and rescue operations. Author
