Abstract: LABEL APPLICATOR WITH OSCILLATING LABEL            RECEIVER AND METHOD     ABSTRACT OF THE DISCLOSURE          A label applicator comprising a supporting structure, a label receiver mounted on the supporting structure for oscillatory movement about a pivot axis between a retracted position and an extended position, and a label dispenser for supplying labels to the la-bel receiver when the label receiver is in the retract-ed position.  The label receiver releasably retains the labels supplied to the label receiver in the retracted position.  The label receiver is moved in one direc-tion about the pivot axis to the extended position and in that position, applies the label to an article.  The label receiver is then pivoted about the pivot axis in the other direction to return it to the retracted posi-tion.

Abstract: Abstract:    The present invention relates to a phase detection circuit.  The phase detection circuit includes a first phase detector for receiving an input signal and a first reference signal, a second phase detector for receiving the input signal and a second reference signal having a different phase from that of the first reference signal and a level discriminator for receiving the phase detection output of the first phase detector.  The detection operation of the second phase detector can be inhibited directly by means of the output of the level discriminator.  Accordingly, a phase detected output is obtained only when the phase difference between the input signal and the first reference signal falls within a predetermined range.  The phase detection circuit having such a limiting function is suitable for application to an automatic tint control circuit of a color television receiver.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus for manufacturing a square bottom bag is disclosed herein.  The method comprises the steps of driving a web in a first direction and bending the web upon itself across its width as it is driven in the first direction to assume a U-shaped configuration, supporting the main panels of the web in the open U-shaped configuration and folding the side clos-ure forming panels towards one another to an overlapping relation-ship and securing the side closure panels in the overlapping re-lationship to form side walls of a bag.  The bag forming machine consists of a frame, a former mounted in the frame and a guide means for guiding an  unwinding web around the former and drive means for driving the unwinding web around the former.  Folding means is provided at opposite sides of the former for engaging the side wall forming portions of a web and folding them inwardly around the former to form closed side walls of a bag.  Roll stock specifically designed for use in the method and apparatus is pro-vided wherein a first pair and a second pair of bands of adhesive material of a type which is inactive to form a bond until placed in contact with an adhesive of the same type are applied to the inner and outer faces of the  web adjacent said edges thereof.          The bands of the first pair are laterally spaced with respect to the bands of the second pair so as to be out of alignment with one another in successive turns of the roll stock such that the successive turns are not adhesively secured to one another.  An empty square bottom bag is provided which consists of a front wall, a back wall and a bottom wall formed from a unitary panel and in-cluding a band of adhesive on the outer face of said panel extend-ing along the marginal edge portion of each side panel, the panels being folded inwardly so that the band of adhesive on one side panel is disposed at an interface with another side panel and thereby secures the side wall panels with respect to one another in an overlapping relationship to close opposite sides of the bag and retain front, bottom and back walls in an open U-shaped configuration.

Abstract: TEMPERATURE COMPENSATION FOR TRANSDUCER COMPONENTS          ABSTRACT OF THE DISCLOSURE          A circuit for compensating the temperature dependence of the deformation properties of a pressure transducer sensor, having four basic parts:  a current source having an output proportional to the sensor temperature, a constant voltage source, a Norton divider, and an operational amplifier.  One branch of the Norton Divider is a vari-able conductance ladder having an output current which increases at a programmed rate as the current from the temperature dependent source increases.  The programmed rate is based on the temperature-dependent characteristic of the transducer sensor.  The two branches of the Nor-ton divider are connected as inputs to the operational amplifier.  The operational amplifier provides the output of the compensating circuit, which is the difference between the reference voltage of the voltage source and the voltage at the output of the variable conductance lad-der.  As the current source increases, the output voltage of the am-plifier is reduced such that the temperature dependence of the output voltage is a close approximation to the inverse of the temperature dependence of the sensor deformation characteristic.

Abstract: ABSTRACT OF THE DISCLOSURE         The disclosed method and system reduces the ampli-tude of an audio signal as a function of the spectral energy distribution of the audio signal.  The amount of reduction of the entire signal is determined by the ratio of a first signal derived as a function of the logarithm of the signal energy within a first frequency band to a second signal derived as a function of the logarithm of the signal energy within a second fre-quency band.  Undesirable signals (such as those repre-sentative of fricatives) which require greater reduction have a substantial portion of its signal energy within the first band.
