Abstract: ABSTRACT OF THE DISCLOSURE A track aligning device for monitoring the curvature of a track and adjusting the track successively to correct the curvature incorporates three rods mounted on a car or cars running on the track and pivotably connected together, the rods defining three chords each extending between a pair of spaced points located on the track center line.  The angle between the first two rods is measured by a transducer which derives a voltage dependent on the magnitude and direction of the angle.  This voltage is sampled at equal intervals, say two meters, as the aligning device passes along the track. The voltages are summed and averaged electrically and a voltage equivalent to the mean angle between the first two rods is obtained.  The angle between the second two rods is measured by a second transducer and derives a voltage equivalent to the actual angle at a particular position of the track.  This voltage is compared electrically with the mean voltage and an error voltage is derived and used to operate a servo-assisted aligning mechanism to adjust the track to the left or right as necessary.  The deivce can also adjust the superelevation of the track to meet the necessary value as computed on the basis of curvature and speed.

Abstract: ABSTRACT OF THE DISCLOSURE    A design for a metalized electrosensitive label stock, and similar die-cut substrates for electrothermal printing.          Imprinting occurs when an image-bearing stylus at a given potential contacts one portion of the substrate's metalized surface, while a grounded member contacts a nearby surface area.  The flow of current between the stylus and ground causes a selective melting of the label's surface, reveal-ing a colored undercoat.  The labels are die-cut from a label stock in such a pattern as to allow proper current flow while permitting the proper removal of labels.

Motors for vertical and horizontal displacement and rotation are provided. The three motors are controlled by an arithmetic device so that when the examination table is swivelled, the location and position of the image section with respect to the examination table is not changed. In an examination apparatus of this kind, the construction of the examina-tion table may be substantially lighter, because the image section and the counterweights need not be supported by the examination table. The image section can be displaced in a larger area perpendicular to the top of the patient examination table and the patient can be introduced into the apparatus from the left as well as from the right.

Filed: 1979-08-07
Granted: 1982-08-03
Abstract: RCA 71,620 Abstract An automatic gain control keying signal circuit is provided for generating an automatic gain control (AGC) keying signal for a television AGC circuit.  A keying signal is produced upon the normal coincidence of a sync pulse from the sync separator and a horizontal retrace pulse from the horizontal deflection system in a tele-vision receiver.  The keying signal begins upon coincidence of the sync pulse and the horizontal retrace pulse and ends upon termination of the retrace pulse, thereby producing a keying signal pulse of substantially constant time duration, irrespective of the duration of the sync pulse.  According to a further aspect of the invention, an "out-of-lock" signal is produced upon the occurrence of a horizontal retrace pulse which is not in coincidence with a sync pulse.

Abstract: PRINTER ESCAPEMENT CONTROL SYSTEM          Abstract of the Disclosure Disclosed is a digital escapement control system in which the motor (DC) control is completely digital requiring no tachometer generation of feed back signal nor any analog to digital convertors.  Connected to the DC motor shaft is a code wheel and detector to determine the time between discreet positions of the motor shaft as it rotates.  The time between discreet positions is then compared with a desired time, and the difference is stored, as by a register.  The difference is then converted to a pulse-width-modulated (PWM) signal which directly controls the rotational velocity of the motor, increasing or decreasing it as necessary.  The system operates, in a ramp, open loop start up mode and digital velocity controlled braking mode while in the motional mode with the feed back as described above.  At start up, provision is made for inserting the feed back loop when the velocity reaches some predetermined level or percentage of the desired velocity.

Abstract: TRACKING CONTROL APPARATUS FOR A ROTARY HEAD, VARIABLE SPEED SIGNAL REPRODUCING SYSTEM                 ABSTRACT OF THE DISCLOSURE         The present invention is intended for use in a signal reproducing system of the type having at least one rotary trans-ducer for scanning traces across a movable record medium, such as a magnetic tape, to reproduce signals from previously recorded record tracks.  Each transducer is supported on a displaceable support member that is responsive to control signals to displace the transducer relative to the record tracks.  The record medium is movable at a speed which may be less than, equal to or greater than the speed at which the signals originally were recorded.          A frequency generator generates speed representing pulses whose frequency is a function of the speed at which the record medium is moved.  A cyclical, or resettable, counter cyclically counts the speed representing pulses.  A level generator generates a signal level corresponding to the count then present in the counter at the time that a transducer advances to the middle portion of a scanning trace.  The generated signal level is used as a control signal to correspondingly displace the transducer support member.          This displacement provides general compensation for the deviation between the scanning trace of the transducer and the record track which is scanned thereby.  In a preferred use of the present inven-tion, the signal reproducing system is a VTR, and tracking compensa-tion is provided for slow or fast modes of reproduction.  In accord-ance with another feature, a sawtooth signal having a period equal to a head scanning period, and an amplitude determined by the speed at which the record medium (or tape) is moved is added to the generated level in order to provide substantially continuous error correction of the head scanning trace.                             -i-
