Abstract: PAINT CAN POUR SPOUT      ABSTRACT OF THE DISCLOSURE           A pour spout and paint brush wiper attachable on paint containers.  The pout spout has a circular planar member with a square aperture, two edges of which are integral with a pouring spout to facilitate the pouring of paint from the paint container. The circular edge of the planar member has an inverted channel-shaped flange capable of being conformingly snapped over the securing bead of a paint container, while the upper surface of the planar member has a raised rim circumscribing the square aperture and terminating in an integral connection with the spout to prevent the spilling of paint beyond the edge of the pour spout.

Abstract: S P E C I F I C A T I O N             IMPROVED ROTARY FOOD PROCESSING APPARATUS                Inventor:  CARL G. SONTMEIMER     ABSTRACT OF THE DISCLOSURE           In food processing apparatus having a working bowl with a motor-driven shaft extending vertically upwards through the bottom of the bowl and various selected rotary tools having disc-like cutting tool members positioned in the top of the bowl which can be engaged with this shaft for processing food introduced through a feed tube in a cover secured over the bowl during use,  improved rotary food processing apparatus is provided preventing the cutting surfaces of the disc-like member from inadvertently coming into contact with the under-¦ surface of the cover.  The disc member is provided with one or more rounded bearing elements elevated above the cutting elements by a small amount, for example in the range from 1/32  to 3/32  of an inch.  These bearing elements are posi-tioned closely adjacent to the periphery of the disc member, and in one illustrated embodiment the bearing element is formed directly at the periphery, thereby not impeding the feeding of food items to the cutting elements in the disc member.  In normal operation the cutting elements clear the cover by a slightly greater amount than the elevation of the bearing elements for example 1/8th of an inch, such that these elevated bearing elements also clear the undersurface of the cover.  In the event that the user inadvertently overloads the rotating disc cutting tool in either manner described, these bearing elements advantageously slide against the undersurface of the cover almost effortlessly for holding the cutting ele-ments spaced slightly away from the horizontal undersurface of the cover thereby protecting both the cover and the rotating tool.

Abstract: APPLICATION OF:  J. Gerald Smith FOR:  IMPROVED METHOD AND APPARATUS FOR       HARVESTING SHEARED TREES           A B S T R A C T                           OF THE DISCLOSURE         An improved apparatus for processing sheared trees is provided, as well as the harvesting apparatus for use therein.  The harvester is of the type having a gripping means disposed adjacent the forward end of the apparatus and a shear and delimber longitudinally movable relative to the boom.  The hear and delimber are initially positioned adjacent each other and during the first rearward delimbing stroke, the de-limber moves rearward relative to the shear.  At the end of the delimbing stroke, the shear is activated to sever a first bolt, then a greater pressure is applied to the delimber blades so that they are able to grip the remaining trunk for the return stroke, during which the delimber moves forward relative to the shear.  Thus, at the end of the return stroke the delimber and shear have returned to their initial posi-tions and the delimbed portion of the remaining trunk extends a sufficient distance forwardly of the shear to be clamped by the gripping means.  The pressure on the delimbing blades is reduced to the regular delimbing pressure, and the harvester - i -is then in a position to perform a second delimbing stroke, followed by a second return stroke, and if necessary, a third set of strokes.  Thus, it is possible with the method and harvester provided herein to quickly and efficiently delimb a tree trunk of any length with only one shear and delimber assembly.                    - ii -

Abstract: CODE SCANNING SYSTEM                ABSTRACT OF THE DISCLOSURE           The specification discloses a binary code reading system in which a code strip is formed of spaced retro-reflective segments in a reglet and which are selectively blocked by runners to define a binary code.  Detectors spaced at intervals corresponding to adjacent segments read the code strip as it passes the detectors which are coupled to an OR gate for developing clock pulses directly from the code strip for each segment being read.  One of the detectors is coupled to a storage device having a clock input terminal coupled to the output of the OR gate through a multivibrator for synchronizing the entry of the code into the storage device.  The sorted code, read from the code strip on a moving article can be utilized in a conveyor system, for example, for sorting of the article.

Abstract: ABSTRACT OF THE DISCLOSURE          An I-beam section traveling from the apparatus in which it is fabricated is cut on the fly by a die set or shear which is moved with the I-beam.  The cut is effected by a stepped blade having a leading cutting edge and a trailing cutting edge, the latter being in the same plane but laterally offset from the former.  The cut proceeds at a 45° angle to the plane of the web and flanges.  The leading edge enters the I-beam at the middle of the web and cuts the remainder of the web and the lower flange.  The trailing blade edge engages the margin of the upper flange and cuts through this flange and the remainder of the web.  The cutting blade is mounted on a reciprocable upper shoe and the I-beam is fed through structure mounted on the lower shoe which has an opening for the I-beam to pass with considerable clearance.  Inserts mounted on the lower shoe underlie the web and flanges of the I-beam to support the beam during the cut.  Known apparatus may be used to accelerate the die set into sychronism with the moving workpiece and to reciprocate the upper member for the cutting stroke.
