Abstract: 904,159. Feeding magnetic tapes. AMPEX CORPORATION. Aug. 3, 1960 [Aug. 13, 1959], No. 26968/60. Class 40 (2). [Also in Group XL (b)] A tape recorder has pneumatic sensing means to detect the ends of the tape and tape breakage and pneumatic servo means to regulate tape tension. Orifices in sensing posts 16, 23 connected to a common air supply 34 are aligned with the tape bights emergent from the reels 12, 13, such that back-pressures, corresponding to tape/post spacings arise in pipes 28, 29 differentially connected to a ballvalve 36, which cuts-off the air supply to the " take-up " post as the tape approaches closely to the " feed " post. Near the end of the tape, the " feed " post is fully sealed by the tape and the pressure at the point 38 rises sufficiently to operate a pneumatic switch (Fig. 3, not shown), which halts the tape drive. Tape guides 14, 22, rotatable to accommodate two tape widths (see Fig. 5) have appropriate orifices 88a, 88b, the outlets 91 being connected to the outer faces of diaphragms 103 of a transducer, Fig. 7, the inner faces being subjected to a pressure regulated by a ball 117 according to the desired tape tension. The emergent air cushions the tape at the guides and the back-pressure is a measure of the tape tension. A light 112, obturated by shutters 111a, 111b, connected to the diaphragms, operates photo cell/amplifier means (Fig. 4, not shown), which feed servomotors driving the tape reels. Should the tape break, the back-pressures disappear and one diaphragm moves to operate a stop switch 128.
