Abstract: SHIFT CONTROL DEVICE          Abstract of the Disclosure:          An automatic multiratio drive transmission having an automatic shift control system with a speed and throttle position pressure controlled shift valve controlling shifts between the highest drive ratio and the next lower drive ratio.  When the shift valve is in the lower drive ratio position, a normal speed pressure signal increasing with increasing speed acting on the shift valve overcomes an opposing bias force controlled by throt-tle pressure to upshift the shift valve to the higher drive ratio position at increasing upshift speeds for increased throttle positions and provides an upshift hysteresis force decreasing with increasing throttle positions to prevent shift cycling as the highest ratio is established in a short time period and after a longer time delay period reduces the normal speed related gov-ernor pressure in an amount equal to the upshift hysteresis force at full throttle so that the downshift speed is the same as the upshift speed at the full throttle position.

Abstract: POLYMERIC ACRYLONITRILE FILMS AND METHOD OF MAKING SAME     ABSTRACT OF THE DISCLOSURE         Method of preparing films of acrylonitrile polymer exhibiting very high tensile strength, stiffness, optical clarity, and outstanding gas barrier properties.  Method en-tails extruding a hot, concentrated solution of said polymer in a solvent therefor that is water-soluble, e.g., dimethyl sulfoxide, onto a film-supporting surface, e.g., a flat surface, or a drum, which, preferably, has a low energy sur-face such as provided by wetting the surface with aqueous dimethyl sulfoxide, or coated with polytetrafluoroethylene, or other suitable means to thereby form a film.  The resulting film is then contacted with an aqueous medium, e.g., water to remove the solvent (e.g., dimethyl sulfoxide) and partially replace it with water, this treatment being effected under conditions that will prevent the film from curling or puckering.      The resulting film is composed essentially of acrylonitrile polymer and water, and is ignition resistant   This film can be then biaxially stretched in a substantially non-drying environment at 100°C or less, preferably at 50-80°C followed by drying to remove the water, while maintaining the film under constrained conditions to prevent or limit the degree of lateral and longitudinal shrinkage.  The final film thus produced has a very high tensile strength and stiffness and very low gas permeability.

Abstract: COMPENSATED SIGNAL ISOLATOR     ABSTRACT OF THE DISCLOSURE A device for coupling a signal value out of a circuit which itself is floating at some relatively high voltage (termed common-mode voltage). A sensor for converting the parameter to be measured to a signal voltage, together with an amplifier and light-emitting diode are powered by a floating power supply of minimal power rating at the location of the common-mode voltage. An optical fiber link, which itself has great electrical insulation characteristics, joins the LED with a solid state light-to-electric transducer at a relatively remote location. Circuit means responsive to the light-to-electric transducer are included for outputting an analog value representative of the quantity to be measured at the point of the common-mode voltage. This LED, fiber optic link and light-to-electric transducer constitute a first OCI (optically coupled isolator). An additional OCI having the same characteristics as the first is located at the remote point and includes a second LED, optical fiber linked and a second light-to-electric transducer which generates a signal representative only of the extraneous variations produced through the first OCI. The resulting signal is differentially added as a feedback term to the signal produced by the first OCI to provide a compensated analog signal output.

Abstract: ABSTRACT OF THE DISCLOSURE      A one-step easy-open composite container for dough products and the like, together with a method and apparatus for forming the same, are disclosed, which composite container includes a fibrous body wall layer having an unbonded helical butt joint, an impervious inner liner layer that is folded to define an expansible folded portion that extends helically the length of the container opposite the helical butt joint, an outer label layer wound helically in adhesively-bonded relation upon the body wall, across the butt joint, and at least one end closure member closing one end of the body wall-label laminate, characterized in that the overlapping edge of the outer label layer is precut--prior to winding on the body wall layer--by a tab cut which is arranged at an acute angle relative to the separation line of end cut in laterally spaced relation to the helical butt joint.  Consequently, when the pull tab portion defined by the tab cut is pulled to partially tear the label from the container, the body wall butt joint is exposed and is automatically expanded by the product packaged in the container to open the inner liner layer folded portion along the butt joint.

Abstract: Abstract of the Disclosure An automatic background brightness control for document copiers of the type using automatic feeders for advancing original documents along a transport path to an imaging platen at which the documents are copied.  As the feeder advances n document to the imaging platen, one or more light sources disposed at spaced locations across the transport path direct scanning beams onto the indicia-bearing side of the document.  Photodetectors sense the light reflected from the scanned portions of the document to provide signals indicating the reflectance of the scanned portions,  A signal-processing circuit responsive to the reflectance signals generates a background brightness control signal representing the maximum reflectance sensed by any of the detectors.  The background brightness control signals regulates the intensity of the exposure lamp of the copier when the document reaches the imaging platen.  In one alternative embodiment, the background brightness control signal regulates the width of an optical slit disposed adjacent to the photosensitive surface.  In another alternative embodiment, the background brightness control signal regulates the effective aperture of the focusing lens.

Abstract: ABSTRACT          The following specification disclose a chesterfield that is convertible into a double bed without a requirement for changing any part of the chestrfield frame and which has the normal seat depth for sitting comfort.  The bed is stored beneath the seat cushions and is foldable inwardly lengthwise of the chesterfield with part of the folded bed storable beneath the back rail or deck of the seat.  The bed is folded lengthwise and consists of a pair of clam-shell appearing tube members pivotably attached to a pair of channel members with link fabric for holding a mattress stretched between the tubes and a mid- cross tube.  The channels and tubes form a 'U' shape when folded down into the bottom of the chesterfield with the opening of the 'U' facing the back of the chesterfield.  The bed frame is held to the lower side frames of the chesterfield by ? bearing bracket through a chain of links connected together in pivotable foldable relation.    A 'U' shaped torsion tubs is pivotably connected to each side bracket accross the bottom of the chesterfield with the arms of the 'U' connected to the chain of links to become the legs of the bed proximate the chesterfield when the bed is folded out.    Another pair of legs is connected to the chain of links to fold out with the unfolding of the upper half of the clam-shell to form the front legs of the bed.  The linkages from the front legs through the torsion tube to the bracket form an upwardly thrusting bridge to maintain the bed in load bearing rigidity in the out-folded position without the necessity for a mid-section support or leg.

Abstract: ABSTRACT OF THE DISCLOSURE A process for the stabilization of a fluidized bed against bubble formation in an apparatus which comprises a vessel, a plurality of permanently magnetized particles dispersed throughout the bed, and means for fluidizing said particles.  The particles are designated as permanently magnetized by virtue of their possessing a coercivity of at least 50 oersteds.  The perma-nently magnetized particles exert magnetic attractive forces upon one another, thereby imparting stability to the fluidized bed.  In these beds, fluid throughput rates which are up to 10 or more times the flow rate of said fluid at incipient fluidization of the unmagnetized particles can be achieved with little or no bubbling and at bed pressure drops equal to bed weight.
