Abstract

887,149. Automatic tension-control systems. INSTITUT FUR SCHIFFBAU ROSTOCK. Oct. 7, 1958, No. 31958/58. Class 38 (4). The tension in a touring cable 2 is detected by a roller 1 biased by a spring 2. Movement of the roller, through a rack and pinion, rotates a transmitter 6, electrically connected to a tension indicator on a controller 8, and rotates a transmitter 3 controlling the energization of a Ward-Leonard generator 5. Variation in cable tension is corrected by the generator 5 varying the supply to a motor 4 which drives a winch-drum 9 so as to take in or pay out cable. The output voltage of the generator is zero when the cable tension is at a desired value. A transmitter 7 mechanically coupled to the winch drum is electrically connected to a cable length indicator 15 having a limit contact for interrupting the supply to the transmitter 3 to prevent further cable being paid out.
