Abstract: ABSTRACT OF THE DISCLOSURE             An optical scanning apparatus comprises a scanning device for linearly scanning an incident beam of light from a light source, a concave mirror for receiving and reflecting the scanned incident beam from the scanning device and a cylindrical lens in the path of the scanned incident beam reflected by the concave mirror for deflect-ing the beam onto a surface to be scanned, whereby light reflected from that surface in a scanned reflected beam passes back through the cylindrical lens and, separated from the incident beam, falls on the concave mirror and is reflected to the scanning device, from which it issues as a positionally fixed reflected beam.  A deflection mirror deflects the scanned reflected beam so that the scanned reflected beam falls on the scanning device so as to over-lap the location of the scanning device on which the incident beam from the light source falls, whereby the reflected beam and incident beam lie on divergent paths; and a light collector spaced from the light source lies on the path from which the reflected beam travels from the scanning device.

Abstract: FLEXIBLE CABLE CONTROL AND TAKE-UP MECHANISM          (Abstract of the Disclosure) A control and take-up mechanism for controlling and protecting at least one elongated cable and the like which may be employed to supply operating power, fluids, controls and so on to an operating member mounted within an apparatus and wherein the operating member is selectively movable within the apparatus through an operating plane between a first position and a second position spaced there-from.  The take-up mechanism is comprised of an arcuate cable trough fixedly mounted to the apparatus in a plane parallel to the operating plane with a portion of the elongated cable leading to the operating member longitudinally disposed therein.  A cable wheel assembly is received in the trough in rolling engagement therewith and includes a hub and opposed sides which define a cable channel therebetween. The cable wheel assembly is constructed so that the sides and hub are rotatable about the assembly axis independently of each other in order to eliminate undesired sliding of the cable in the trough and/or around the hub during pay out of the cable in response to movement of the operating member between the first and second positions.  The cable extends from its source through the trough, around a portion of the cable wheel assembly hub and then to the operating member itself.  When the operating member is in the first position, the cable wheel assembly is disposed adjacent one end of the cable trough and as the operating member is moved toward the second position, the cable wheel assembly is pulled by the cable tension along the trough toward the other end thereof. Biasing means communicate with the cable wheel assembly to continuously urge the assembly toward one end of the cable trough against the tension of the cable.  Means are also provided for maintaining the cable in substantially the same degree of contact with the wheel assembly hub as the cable moves therearound when the operating member is moved between the first and second positions.

Abstract: ABSTRACT OF THE DISCLOSURE   A highly viscous mass to be homogenized is fed from a screw plas-ticizer into a mixing  chamber, perpendicular to the plasticizer mouth, in which a mandrel rotates independently of the plasticizer screw to masticate the mass in a narrow annular clearance between itself and the chamber wall. The mass, force-fed through this clearance by the screw pressure, encounters several sets of free-floating balls or other rotary bodies loosely guided in annular grooves of the chamber wall, or of the mandrel, while revolving about the mandrel axis.  The mandrel may have a screw-threaded rearward extension for admixing additional ingredients from one or more further chamber inlets with the mass to be homogenized, with exertion of a back-up pressure upon that mass.  The chamber temperature may be controlled by the circulation of a cool-ing fluid through its wall and/or through the mandrel.

Abstract: ABSTRACT OF THE DISCLOSURE          Visual display apparatus having conductors arranged in a matrix forming a plurality of crosspoints includes an improved light-emitting diode connected across each crosspoint. The diodes are electrically energizable via the matrix to form an image and individual ones of the diodes are positioned relative to their respective crosspoints so that every light-emitting diode junction is provided an unobstructed path for its emitted light.  An embodiment for coloured image displays includes a shadow mask overlying the matrix with apertures in the mask aligned in registry with the diodes to direct the light outwardly of the matrix.  Three transparent lamina overlie the mask and each lamina carries a predetermined array of photon activated fluorescent material that emits light having one of the additive primary colours of red, green and blue.  The combined array of fluorescent material forms a plurality of colour triads corresponding to crosspoint triads which are energized by horizontal and vertical scan means to provide a resulting scan that consecutively energizes all the crosspoints in a predetermined order.

Abstract: "GROUND-ROLLING FORWARDLY-DIRECTED ROTARY BALER"     ABSTRACT OF THE DISCLOSURE   A rotary baler is provided, front mounted on a self-propelled power unit, to ground roll cylindrical bales of fibrous material. A pick-up assembly at the rear of the baler lifts the fibrous material from the ground to engage a generally vertical rear belt assembly which moves the material upwardly.  Rotating discs at the upper end of the rear belt assembly deflect the material forward to engage a forwardly extending upper belt assembly which biases the material for-wardly.  The upper belt assembly is. pivotally mounted at its rear end so that it can rotate with the expansion of the forming bale. Flexible lengths. of cable hang down forward of the upper belt assembly; these cables act to shape and contain the forward portion of the forming bale.  A spring-biased arcuate arm assembly, positioned intermediate the upper belt assembly and the cables, guides and compresses the forming bale once it has reached a pre-determined size.  A twine assembly at the front of the baler is actuated by contacting the surface of the rolling bale; the twine assembly automatically wraps the bale and cuts the twine as the formed bale is discharged from the baler.
