Abstract: PHASE TRACKING LOOP CIRCUIT     ABSTRACT OF THE DISCLOSURE         A phase-tracking loop circuit which can be used, for example, as an FM detector or as a frequency-tracking control cir-cuit to control the index signal of a beam-index cathode ray tube (CRT), includes an adder receiving an input signal of fluctuating frequency, a tracking filter coupled to the output of the adder and whose passband center frequency is shiftable, in response to a control voltage, to follow changes in the frequency of the input signal, an attenuator feeding an attenuated version of the output from the tracking filter back to the adder for combining in the latter with the input, and a phase comparator comparing the phase of the output of the adder with the output of the tracking filter to provide a corresponding control voltage to the tracking filter.  If used as an FM detector, the control voltage can also constitute a demodulated signal.  If used to control color switch-ing in a beam index CRT, a controlled signal tracking the phase of the index signal can be derived from a phase-locked loop circuit which provides one of the inputs to the phase comparator in response to the output of the tracking filter.                             -i-

Abstract: TITLE OF THE INVENTION:     FORCE APPLICATION APPARATUS     ABSTRACT OF THE DISCLOSURE:     A force may be applied to any point along a line which may be straight or curved in a plane or in space.  For this purpose a force applicator is used which includes a pressure expandable hose section closed at its ends, a reaction mem-ber against which the hose rests, and a pressure transmitt-ing plate moving in response to an expansion of the hose.          These three elements are held in an operative position rela-tive to one another by a modular frame section which also holds a guide member and a reset element for restoring the hose section to a starting position when no pressure is applied inside the hose.  A piston rod extends through the guide member and is operatively connected to the pressure transmitting plate.  The modular frame section, the guide member and preferably also the reset element form a modular unit.  A plurality of such modular units may be arranged along an elongated hose section, whereby a respectively elongated reaction member and a correspondingly elongated pressure transmitting plate are provided in common for the plurality of modular units.  A modular frame section or sections may also be used to hold adjustable stroke limiting elements.

Abstract: D. J. Anspaugh-R. R. Siegrist 1-1 MOTOR MOUNT STRUCTURE FOR VEHICLE SEAT ADJUSTMENT APPARATUS            ABSTRACT OF THE DISCLOSURE: An apparatus for fixing the relative position of components within an automotive seat track mechanism. Such mechanisms are conventionally powered by electric motor drive, such as a motor with multiple armatures or by using separate motors mounted on a unitary platform or by using clutch activated members driven by a single motor. The output of the motor drive is transmitted through respective gearing to lead screws or rack and pinions within or adjacent to the tracking structures at both sides of the seat to translate the seat horizontally. The motor drive output is also transmitted to operate individual lead screws or rack and pinions within or adjacent one structure for the vertical seat movements. The motor mount is secured to the tracking structure at one side of the seat. A simple light weight holding rod secures the motor mount to the opposed side structure to produce a rigid, yet readily detachable motor mount. The motor mount can more readily withstand shock and vibration, especially during shipping and assembly of the seat track mechanism.

Abstract: ABSTRACT OF THE DISCLOSURE     A video tape recording/reproducing apparatus for reproducing video signals recorded in successive parallel tracks on a magnetic tape, includes a magnetic head movable in a direction generally along each of the tracks in a scan-ning path from a beginning end to a concluding end thereof for reproducing signals recorded therein, and a bi-morph leaf for mounting the head and being operative to deflect the head in a direction transverse to the direction along the tracks.  During the scanning operation, the bi-morph leaf is supplied with a dithering signal for wobbling the head tranversely with respect to the longitudinal direction of the record tracks, a tracking error signal to correct deviations of the head trace from the tracks to be scanned and a slant compensation  signal to correct any inclination tracking  error of the head.  During the non-scanning opera-tion, a jump signal is supplied to the bi-morph leaf for deflecting the head to accurately scan the beginning of the tracks.  The present invention also includes a sample and hold circuit and a comparator circuit for producing a pola-rity signal corresponding to the direction of any deviation between the scanning trace of the head and the track then being scanned thereby, at the beginning end of the scanned track, and an UP/DOWN counter for producing and storing a control signal and for supplying the control signal to the bi-morph leaf so as to control the latter to deflect the head to accurately scan the beginning ends of the tracks, the counter being controlled by the comparator circuit to change the value of the stored control signal by an incremental amount by counting either UP or DOWN during each scan in accord-dance with the direction of the deviation at the beginning ends of the tracks.     1a

Abstract: ABSTRACT Two  switching  elements  are  cross-coupled  in  the  standard bistable multivibrator arrangement.  Two additional switching elements are added: one  each in  parallel with  one of  the switching  elements forming the bistable multivibrator.  The  two wave forms under study  are applied to the  control gate  of each of  the additional  switching elements.  When both wave forms are in one  state, the two additional switching elements are switched  ON, effectively inhibiting  bistable multivibrator action. The first wave form to change  state results in its associated switching element switching OFF, which releases the bistable multivibrator circuit to assume the corresponding  stable state, which observed differentially across  the  switching element  forming  the bistable  multivibrator, is indicative  of the  wave form  to first  undergo transition.   After the first  wave form  has undergone  transition, the  bistable multivibrator becomes  insensitive  to the  subsequently  occurring transition  on the second wave  form, and the  circuit remains in the  defined stable state until  both  wave  forms  again assume  their previous  state  prior to transition,  in  which,  once  again, bistable  multivibrator  action is inhibited.
