Abstract: SELF TRACKING TUNER           ABSTRACT OF THE DISCLOSURE A tuner includes a channel or target frequency selection means, a tunable oscillator, a tunable circuit means having at least one tunable circuit, and tuning means, responding to the target frequency select means, for auto-matically and individually tuning the tunable circuit. Typically the tuner includes several tunable circuits, which are tuned successively.        The illustrated embodiments have three individually controlled varactor tuned circuits and a varactor tuned oscillator.  To move to a new target frequency, the tuner locks the oscillator to the target frequency via a phase locked loop.  This target frequency is inputted to the first varactor tuned circuit, and a microprocessor cooperating with a DC detector for sensing the output of the set of tuned circuits steps a voltage step generator which controls the first varactor tuned circuit while the tuning of the other varactor tuned circuits is held fixed.  The microprocessor adjusts the voltage step generator to maximize the DC output and signals corresponding to this voltage are stored in a memory.  Next, the second varactor tuned circuit having a corresponding voltage step generator is adjusted in the same way, and corresponding signals are stored in memory. This continues until all varactor tuned circuits are locked to the target frequency, after which the varactor tuned oscillator is returned to its standard frequency of 43.5 MHz greater than the target frequency.     In a second embodiment, one oscillator remains at 43.5 MHz higher than the target frequency and cooper-ates with a mixer and a 43.5 MHz oscillator to provide a target frequency signal for use in the self-alignment procedure.

Abstract: ABSTRACT Apparatus is disclosed which is suitable for deshirring and smoothing a shirred tubular casing as the casing is being stuffed.  The tubular casing has an interior surface of predetermined internal diameter when unshirred. The apparatus includes a hollow body of generally annular configuration having a circumferential wall of generally circular cross-section which defines a closed external surface having a diameter which increases from a first end to a maximum at a second end of the hollow body.  The hollow body has a central opening for receiving a stuffing tube and an external surface of the stuffing tube is releasably engaged to mount the hollow body on the stuffing tube.  The hollow body is constructed of a rigid material, and the maximum diameter of said external surface is smaller than the predetermined internal diameter of the unshirred tubular casing.  When the hollow body is arranged within a de-shirred section of the tubular casing, the tubular casing and the hollow body are mounted on the external surface of the stuffing tube, and the casing is stuffed with a mixture from the stuffing tube, the interior surface of the tubular casing slides over the generally circular external surface of the hollow body and is thereby deshirred and smoothed.

Abstract: RENDERING DRYER                      ABSTRACT   A dryer is provided with interacting heat transfer stator and rotor for improved processing capability.  The stator comprises a stationary row of planar heat exchange banks supported within the vessel of the dryer.  The rotor has a complemental number of annular heat exchange vanes interleaved between the heat exchange banks of the stator to create desired low-level agitation of the processed material as the rotor turns and to provide increased heat transfer efficiency.  The vanes on the rotor and the banks of the stator each comprise an open grillwork of tubular members whereby the processed material may flow freely through the vanes and banks for additionally increased heat transfer efficiency and reduced residence time for the material.

Abstract: FLUIDIC MOTOR ACTUATOR                       ABSTRACT OF THE DISCLOSURE A control system for a motor through which a specific rotary output is obtained from a given input signal by controlling an operational supply of fluidic energy.  The control system includes a direct mechanical servo which receives the input signal to control a rotary plate directional valve through which the operational supply of fluid is communicated to the motor.  The direct mechanical servo includes a compound epicyclic gear train and an intermittent motion gear mechanism which compares the input position with the output position of the motor to establish a feedback signal which repositions the rotary valve plate directional valve to a null position when the rotary output equals that requested by the input signal,  The control system further includes a regulator assembly which receives a variable reference signal to control the fluid pressure of the supply fluid.  The variable reference signal which represents the work performed by the motor also passes through a relief valve. When the output torque of the motor reaches a predetermined value, the relief valve opens and a portion of the fluid supplied to the motor is vented to an exhaust conduit to protect any mechanism operated by the motor from receiving excessive torque.

Abstract: METHOD AND APPARATUS FOR FOLDING AND CUTTING ARTICLES FROM A TUBULAR THERMOPLASTIC ENVELOPE     ABSTRACT There is provided an apparatus for producing a plurality of longitudinally folded articles from an elongate, continuous, tubular envelope of thermoplastic material.  Typically, these articles are bags such as garbage bags.  Transverse seals are firstly provided across the tubular envelope at spaced-apart locations, without severing the same, and then folding means are provided downstream of the heat-sealing region, for folding the tubular envelope in a continuous way about a longitudinal line which is usually substantially midway of its width . Severing means are located downstream of the folding means, for severing the tubular envelope transversely at or adjacent the transverse seals, to provide separate, longitudinally folded articles.  A further folding means may be downstream of the first-mentioned folding means, in order to provide a second fold about a longitudinal line which is typically substantially mid-way of the width of the tubular envelope in its once-folded condition. A subsequent station may also be provided for folding the severed articles about transverse fold lines, and this can be done once, twice or even more times. The preferred means for continuously folding the tubular envelope includes the provision of a substantially triangular plate having two edges meeting at an apex, with the apex typi-cally located about midway of the width of the tubular envelope, and pointing in the direction in which the envelope is travelling.  The envelope is pulled along one surface of the triangular plate, and then is led away from that surface obliquely and around a roller, in order to fold the same about a longitudinal line.
