Abstract: Abstract of the Disclosure A switching motor control system that is particularly well suited for the reel motor of a tape transport system in-cludes an energization command system commanding motor energiza-tion in response to tape buffer loop length, a feedback system indicating buffer loop length and actual motor current and a feedfoward system energizing  the motor to reduce the differ-ence between commanded motor energization and actual energization as indicated by motor current.  An integrator which sums the com-mand and feedback signals with an AC reference signal outputs a triangle wave signal that i readily converted to a digital com-mand signal by 8 simple transistor detector.  An economical dig-ital control circuit delays and selectively inhibits the digital command signal to control a motor drive amplifier in a switching mode which avoids power dissipation in the motor drive amplifier.

Abstract: ABSTRACT     A film flaw detection system has capacitive sensing members for sensing capacitance changes in corre-spondence with irregular film variations.  The sensing members take two forms.  One form senses variation in film thickness by using the film as a dielectric between two plates of the capacitor.  Changes in film thickness result in changes in the dielectric and hence in the capacitance.          The other form consists of feelers which ride along the surface of the film and which move transversely to the film movement in response to flaws in the film.  Each feeler forms a plate of a capacitance, and movement of the feeler changes the distance between this plate and an associated fixed plate which results in a capacitance change.  The detecting circuit comprises a phase detection system for measuring phase changes in a high frequency signal.  These phase changes correspond to capacitance changes caused by flaws in the film and sensed by either of the two forms of sensing means.

The de-vice comprises a friction clutch including first and second cone clutch members, a positive clutch including first and second jaw clutch members, a plurality of springs reacting between the second members for biasing the second cone member toward engagement with the first cone member, a stop means for preventing engagement of the second cone with the first cone member until initial sliding movement of the first jaw member, and a blocker means for preventing engagement of the positive clutch until the friction clutch brings the gear to substantial synchronism with the shaft.          The second jaw member includes an outer circumferential surface which supports an inner circumferential surface of the second cone member.  The blocker means, which are defined on the outer and inner circumferential surfaces, allow limited relative rotation of the second cone clutch member on the second jaw member and prevent sliding move-ment of the second jaw member into engagement with the first jaw member until substantial synchronism is reached.          Initial movement of the second jaw member engages the friction clutch through the springs; thereafter, force for engaging the friction clutch is transmitted through the blocker.

Abstract: LOOM STORAGE FEEDER IMPROVEMENT                           ABSTRACT The disclosure relates to a system and method for matching yarn withdrawal speed from a yarn supply package and utility means such as a shuttleless loom thereby re-ducing the possibility of supply package sloughs and yarn breakage caused by conditions such as large changes in load-ing on an intermediate rotary drum type yarn feeding and tensioning storage device.  Thus, the drum of the storage device is driven by a d-c motor controlled to provide a con-stant drum drive speed thereby withdrawing yarn from the supply package at a constant rate.  said rate is slightly higher than the consumption rate of the utility means.  The drum speed is maintained constant by a feedback system which avoids changes in speed of the drum except when occurrences of an overfill of yarn on the drum occur.  Thus, a constant speed drum drive system in this invention replaces variable speed or constant torque drum drive systems of the prior art which drive in relation to loom consumption resulting in frequent storage feeder stops and starts which in turn re-sult in package sloughs and/or yarn breakage.
