description	1320051 Intermittent tape drive systems COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT ALCATEL 22 April 1971 [22 April 1970] 10855/71 Headings G4M and G5R In a high speed intermittent tape drive system, rapid fluctuations in tape movement are accommodated by lateral displacements of light pulleys. In the arrangement shown, supply and take up reels 10, 30 rotate continuously, but the punched tape B is alternately braked/ driven in the region of a head 22 by brakes 23 and a capstan/pinch-roller system 24, 25, appropriate control signals 70 being fed directly to the brakes 23 but being inverted at 71 before being fed to the capstan 24. Rapid give/take motion is provided by displaceable pulleys 41 61 on pivoted arms 42, 62 under the control of springs 43, 63 and solenoids 44, 64, the control signals 70 being delivered to the solenoids via differentiating/delay devices 40, 46/50, 51 and a gate 52 as indicated. Heavy pulleys 12, 14, 32, 34 on heavy arms 15, 35 accommodate low speed tape fluctuations.
