Abstract: APPLICATION OF CHARLES W. NIES AND DONALD A. EVERT DUAL REEL HUB A dual reel hub assembly for securely mounting two confronting reels coaxially while allowing independent rotational operation thereof has an axially inward hub structure for mounting an inner reel and an axially outward hub structure for mounting an outer reel.  The inward and outward hub structures are mounted on a common central spindle, or shaft, with the inward hub structure being free to rotate on the shaft while the outward hub structure is fixedly attached to the shaft and spaced from the inward hub structure.  Each hub structure includes a reel support shell having an outer surface for supporting an inner circumferential surface of a circular axial opening in a reel.  A plurality of radially outwardly extending key pins are linearly aligned parallel to the shaft axis and are mounted on each reel support surface and are arranged to mate with one of a plurality of longitudinal grooves, or keyways; on the circumferential inner surface of the axial reel opening.  A rotatable locking ring on each hub structure is dimensioned to pass through the reel axial opening and has radially outwardly projecting locking fingers equal in number to the longitudinal grooves and dimensioned to pass therethrough.  A selective rotation of the locking ring is used to position the locking fingers against a reel face.  On the inner hub structure, the locking ring is spring biased toward a radially outwardly projecting circumferential flange located at the opposite end of the hub shell from the locking ring.  On the outer hub structure, the locking ring is spring biased toward a rotatable flange segment plate dimensioned to pass through the reel axial opening and having radially outwardly extending flange segments equal in number to the longitudinal grooves and dimensioned to pass therethrough.  A selective rotation of the segment plate is used to position the flange segments against a reel face.  An actuator assembly in the outer hub structure selectively connects the inner and outer hub structures to enable the locking rings and flange plate to be rotated to position the locking fingers and flange segments either aligned with the longitudinal reel grooves or against respective reel faces.

Abstract: ABSTRACT OF THE DISCLOSURE      An automatic tracking servo control system which is adapted to control the tracking of at least one rotary signal reproducing transducer which scans successive parallel record tracks on a movable record medium.  Position pulses are generated when the transducer rotates into predetermined position with respect to the record medium, and these positions pulses are used in conjunc-tion with control signals which are reproduced from the record medium and which had been recorded at spaced locations therealong in predeter-mined relation to the record tracks for controlling the position of the transducer with respect to the tracks scanned thereby.  A detector detects the relative strength of the signal reproduced by the trans-ducer during periodic intervals.  A phase shift circuit shifts the phase of the position pulses by a selected amount during successive scanning cycles of the transducer, this amount being periodically adjusted as a function of the difference between the relative signal strengths in successive periodic intervals.  The phase-shifted posi-tion pulses are used in a servo circuit, together with the control pulses, to control the tracking of the rotary head.

Abstract: ABSTRACT OF THE DISCLOSURE      An edge sharpener, in particular for sharpening the steel edges of skis, is composed of a main body in which there is a recess for holding a file blade and within which is inserted a clamping wedge so as to exert distributed forces on the surface area of the file blade when the clamping wedge is forced into the recess substantially radially. In a particular feature of the invention, the main holder has a flexible foil which comes to lie between the pressure surface of the clamping wedge and the surface of the file so that movement of the clamping wedge does not result in abrasive contact with the surface of the file.  The lower part of the clamping wedge has an inclined surface which cooperates with a similarly inclined surface in the holder.  The clamping wedge is further equipped with gripping surfaces so that, during manual use, the force of the hand on the sharpener to execute the sharpening strokes tends to move the clamping wedge more forcefully into the recess, thereby increasing the clamping action.

Abstract: Abstract of the Disclosure An apparatus for receiving and handling empty beverage containers.  The empty containers may be receive either individually or in cartons upon a moving conveyor.  an alignment mechanism separates the containers and moves them to one side of the conveyor. A switch arrangement senses cartons, so that the system can process cartons of empty containers in a different manner than individual empty containers.  The containers, whether individually or in cartons, pass through an illumination station wherein they interrupt illumination falling upon a row of photo-cells.  Output signals form the photocells are transmitted to identification circuitry together with clock signals generated in synchronism with the movement of the conveyor.  The identification circuitry generates registrations signals, which are sued to compute value of the containers being received.  A paddle mechanism shifts the cartons to a separating station, which forwards properly filled cartons to a storage area.  Improperly filled cartons are returned to a point near the receiving area.
