Abstract: DJM:rd PROCESS FOR MIXING AUDIO AND VIDEO SIGNALS            Abstract of the Disclosure:         A method of synchronizing audio and video information is disclosed wherein standard motion picture techniques may be used to form a master finished audio track accurately synchro-nized with a recorded video signal.  A standard master edited video tape is recorded with a conventional SMPTE time code or other code identifying each of the recorded frames.  The video signal and time code are transferred to a first sprocketed magnetic film which operates at standard motion picture speeds.          This film serves as a "work" print which is then used to build a plurality of audio tracks on sprocket driven films which are synchronized with the video information appearing on the work print.  Thereafter, the audio tracks are mixed in synchronism to form a master finished audio track on a second sprocketed magnetic film.  The SMPTE time code is transferred from the work print to the second sprocketed magnetic film in synchronism with the master finished audio track.  The master audio finished track is then transferred in synchronism to the master edited video tape with the stored SMPTE time codes being used to drive the audio film and video tape in synchronism.

Abstract: OPTICAL SENSOR SYSTEM                         ABSTRACT      An optical transducer with an optical waveguide having two paths for the propagation of light is deformed in response to acoustical pressure variations or other parameters to be sensed to modulate the amplitude of the light propagated along the two paths in opposite polarities.  The light outputs of the two paths are sensed by photodetectors and applied to an electrical differencing circuit. The mean values of the photodetector outputs are balanced as by mechanically providing a predetermined bias deformation of the fiber, or by electrically matching outputs of the detectors such that, on the average, the output of the differencing circuit is zero.  Dynamic deformation of the fiber in the transducer results in unbalanced outputs of the photodetectors which unbalance is sensed by the differencing circuit.  This differential detection method minimizes optical and mechanical sources of noise in the light source and waveguide and leads to increased signal-to-noise and enhanced dynamic range of the transducer.                 *    *    *

Abstract: TITLE:  A TOY HAVING A SPLIT MOVABLE MEMBER   ABSTRACT         A toy that includes a housing having at least one object which is movably located in the housing.  Also located in the housing is an object moving member which is a composit of two sections. The sections of this moving member are each indi-vidually movable with respect to one another and each independently movable with respect to the housing.  This individual movement of the sections allows them to move into a cooperative position with respect to one another.  When the sections are located in the cooperative position and main-tained in the cooperative position by coordinating the individual movements of the sections, it is possible to locate the object on the object moving member and move the object from a first point in the housing to a second point in the housing. Movement of the object can be maintained as long as the sections are maintained in a cooperative position, however, if the sections are allowed to deviate from the cooperative position by not coordinating the movement of the sections, the object will become dislodged from the object moving member.

Abstract: ABSTRACT OF THE DISCLOSURE   A normal force applicator for a bottom feeder. The normal force applicator forms a rolling nip between a roller and a drive belt designed to apply force to only a few of the bottom articles in the stack to be fed at a time. Therolling nip ensures a constant normal force between the articles and the feed belt that feeds articles to a separator even using a very low applied force, independent of stack size. Also, since the roller contacts only a few of the bottom articles, additional articles can be added to the stack readily even while the feeder is operating.

Abstract: APPARATUS AND METHOD FOR CONTROLLING THE TENSION ON      A YARN BUNDLE WITHDRAWN FROM A MASS OF COMPACTED YARN                      ABSTRACT OF THE DISCLOSURE         Apparatus and method are disclosed for varying the tension applied to a yarn bundle withdrawn from a yarn mass retained within a confined space.  Initially a compacted yarn mass is introduced into a confined space that is de-fined by a tubular element having a cylindrical wall portion and an elongated slot provided in the cylindrical wall portion.  A yarn bundle is then withdrawn from the end of the yarn mass in the confined space through the elongated slot.  Tension is applied to the yarn being so withdrawn by providing the slot with a width which retains the yarn mass within the confined space.  The tension applied to the yarn bundle is varied as the end of the yarn mass moves from one end to the other end of the confined space.  Such var-iation can be achieved by arranging the slot to extend parallel to the longitudinal axis of the cylindrical wall portion and by providing the slot with a width that increases from one end to the other.  Alternatively, it can be achieved by arranging the slot in the form of a helical passage within the cylindrical wall portion and by causing the yarn with-drawn through the helical passage to wrap around an outside portion of the cylindrical wall portion.  As a further alter-native, the variation can be achieved by arranging a front portion of the slot in the form of a helix and a rear portion of the slot to be linear and parallel to the longitudinal axis of the tubular element.  The yarn bundle is withdrawn initially through the linear portion and then through the helical portion, the yarn wrapping around the outside portion of the cylindrical wall portion after the yarn exits through the helical portion.

Abstract: ABSTRACT OF THE DISCLOSURE     A unique solvent blend and method of conducting vapor degreasing operations is disclosed, wherein synergism is obtained by the addition of a component to three known vapor degreasing solvents The vapor degreasing solvents of the invention comprise a blend selected from the group consisting of perchlorethylene and trichlorethylene or 1, 1, 1, trichloroethane and methylene chloride or methylene chloride and trichlorethylene. The trichlorethylene or methylene chloride component comprises about 0.1 to 90 volume percent of the total degreasing solvent, while the other component of the blend comprises the remainder of the solvent blend The resulting vapor degreasing solvent, has a number of advantages over perchlorethylene alone or 1, 1, 1 trichloro-ethane alone, or in combination with stabilizers, or tri-chlorethylene alone, or in combination with stabilizers Addition of either trichlorethylene or methylene chloride to the solvent blends of the invention extends the normal life of the degreasing solvents alone, or in combination with conventional stabilizers and the like. The degreasing sol-vent blend of the invention not only extends the operational life of perchlorethylene of 1, 1, 1 trichloroethane or trichlorethylene based vapor degreasing solvents, but also reduces the cost of conducting vapor degreasing operations using the conventional vapor degreasing solvents, because initial operational temperatures, for effective vapor de-greasing, are reduced The unique solvent blends used in the method of the invention evidence unique results when used in a vapor degreasing process wherein one of the components of each of the novel blends is found to stabilize the other components of the blend in the presence of contaminants en-countered in the conventional vapor degreasing process.     Governmental code regulations and temperature parameters, under which the degreasing operation are conducted will dictate solvent blends used for results desired.
