Abstract: Abstract A web guide system wherein misalignment of take-up and supply rolls relative to a reference surface may be compensated without tape distortion by a crown pulley and an adjacent concave web guide.  The concave web guide is a fixed, flangeless post about which the web is parially wrapped.  The web tends to be self-centering in the concave curved portion of the guide.  Tape is fed from a roll to the concave guide and then to the crown pulley of minimum radius which is mounted for axial as well as rotational motion.  Pulley axial motion promotes equal edge tension and completes web self-alignment.  Final axial alignment without edge pressure is accomplished by fixed tape edge-guides in the region of the head.

Abstract: A B S T R A C T      A sinusoidal component of phase jitter in a communi-cations channel is reduced by apparatus including means providing an oscillator signal at the receiver and modifying the received signal phase in accord therewith.  Decision means determine the probable transmitted signal and the signals at the input and output of the decision means are compared to determine the residual phase jitter.  The residual phase jitter is compared with a suitably delayed oscillator signal and the results of the comparison are used to alter the modification (by the oscillator signal) of the received signal to further reduce the phase jitter.  Preferably the results of the comparison are also used to reduce the frequency difference between the oscillator signal and the phase jitter.

Abstract: Abstract of the Disclosure A misposition correction system for correcting misposition errors due to spindle runout and other slowly varying errors in a servo positioning system of a magnetic disk storage device.  The system includes means for dynamically measuring misposition error with respect to a data track centerline using an anti-aliasing analog filter, means for digitizing the measured analog signal and for removing selected harmonics of the fundamental-frequency of the resulting cyclic error signal, means for transforming the digitized error signal by a matched digital filter whose transfer function contains independently adjustable DC gain, fundamental-frequency gain, and phase lead components thereby to generate a misposition error correcton signal that matches the electrical and mechanical response characteristics of the servo system.  Further, the system include means to iteratively refine the correction signal by re-applying it to the servo controller when measuring misposition errors with respect to the data track centerline.  The system stores separate misposition correction signals for each transducer on the disk so that one of several correction signals can be selected depending on which transducer in the device is selected.  The system further includes means for generating a bias force correction signal to correct for non-linear position errors resulting from variations in bias forces acting on the transducer carriage over its range of radial displacement.

Abstract: Abstract An improved hitching guidance device to facilitate the coupling of towing and towed units is herein pre-sented.  Such a device is advantageous when the towed unit, with its hitch ball receiver cup, cannot be readily visualized by the operator of the backing unit. The apparatus mounts on the hitch ball and uses elec-trical contacts, acting as switches, to sense the spatial orientation of a fine braided steel wire.  This wire is wound under spring tension on an automatic reeling device and is stretched between the hitch ball and the hitch receiver cup where the wire is in turn fixed to the hitch cup in an exact and known location on the cup by a unique universal adapter clamp.  Information relative to the position of the wire, and therefore relative to the position of the ball and receiver cup and their relationship to each other, is transmitted to the drivers area by a 6 conductor wire.  This in-formation is displayed on a guiding light console, visible to the towing vehicle operator.  By appro-priate response to the information displayed visually and audibly from this guiding light console, an operator can, with utmost precision, position the hitch ball of virtually any towing vehicle under the receiver cup of the towed unit, even under the most vexing of circum-stances.
