Abstract: ABSTRACT OF THE DISCLOSURE         This invention discloses a low-speed disconnect for a constant speed drive transmission.  The constant speed drive transmission has a housing, an input shaft extending into the housing, coupling means in the housing axially aligned with and selectively driven by the input shaft and a driven member splined to the other end portion of said coupling means.  A worm means is splined to the coupling means for relative axial move-ment with respect to the coupling means and a ratchet means is provided on one end of the worm means.  Axially movable one-way detent teeth means extend toward the ratchet means and action between the driven member and the coupling means through the worm means is made for urging the coupling means into coupled relationship with the input shaft.  Gear means are provided to move into contact with the form means whereby rotation of the input shaft and coupling means will thread the worm and coupling means away from the input shaft to disconnect the coupling means from the input shaft and will engage the ratchet means with the one-way detent teeth means so that the coupling means is moved axially away from the input shaft and the one-way detent teeth means prevents the coupling means from reengaging with said input shaft.  This improved low-speed disconnect cannot accidently return to the reengaged position and thus, reduces the likelihood of damage during operation.

Abstract: HEAD TO TRACK ALIGNMENT IN A        ROTATING HEAD MAGNETIC TAPE UNIT           Abstract of the Disclosure The position of a length of magnetic recording tape, adjacent a rotating head device is servo controlled to accurately position a transverse tape data track in alignment with the head path.  The tape includes a longi-tudinal servo track.  A portion of the servo track is read by the rotating head as it sweeps transversely across the tape.  The servo track is formed as a constant fre-quency pattern having periodic sync marks which define the center of a data track.  The rotating head signal constitutes a clock which is used to drive an up/down counter as the head sweeps across the servo track.  The counter's counting state changes as the head sweeps the servo track, such that the residual count, which remains after the head leaves the servo track, is a measure of the magnitude and direction of head-to-track alignment.

Abstract: ABSTRACT OF THE DISCLOSURE    The interior space of a combustion chamber, boiler, or other such gas-filled chamber exhibits an acoustic response spectrum to acoustic energy excitation which includes plural maxima attributable to acoustic natural-vibration frequencies.          The frequencies of these natural vibrations are dependent upon both the interior temperature of the chamber and also upon the molecular weight or standard-conditions gas density of the gaseous contents of the chamber.  One of these two variables, i.e., temperature or else the molecular weight or gas density, is measured by conventional means.  The other variable is then measured using a pressure transducer generating an electrical signal indicative of the chamber interior's acoustic response spectrum, the transducer output signal being applied to a dis-criminator circuit which develops a measurement signal indicative of the value of the variable being measured.  In this way, interior temperature can be continuously monitored by acoustic means with high accuracy.
