Abstract: "TWO-STAGE TRIP RELEASE SHANK ASSEMBLY"          ABSTRACT OF THE DISCLOSURE            An implement shank is pivotally attached to the frame of the implement and normally is maintained in the soil by a heavy-duty coil spring reacting between the shank and a support extending from the frame.  The spring mount and shank holder are connected together so that if the shank trips due to striking an obstruction, the connection moves towards an over center line and if the obstruction is maintained, the connection moves over the over center line.  When it passes over center, it engages a leaf spring extending from the frame which returns the connection back over center when the obstruc-tion is passed whereupon the coil spring returns the implement into the ground.  The coil spring is attached to a resilient member extending from the frame so that the shock load is absorbed as the implement returns to the ground engaging posi-tion, particularly when this return is somewhat rigid due to the heavy-duty nature of the coil spring.

Abstract: ABSTRACT OF DISCLOSURE          An apparatus and process for automatically wrap-ping packages with a full-web or spiral overwrap.  The apparatus includes a film handling assembly in which stret-ched film is wrapped around the load rotated by a turntable.          When the load is stopped in a home position a cutting and sealing assembly is transported into the film path, engaging the film and displacing it out of its original dispensed path.  Rotatable clamps mounted on the turntable are rotated upward to grab the lower portion of the stret-ched film web while the sealing mechanism of the assembly engages the trailing edge of the film web to hold it against the film wrap, after which a cutter blade of the assembly is extended into the film  web, severing the film web so that the load can be transported off the conveyor with the sealing mechanism pressing the trailing edge of the film onto the package wrap.  The sealing mechanism is retracted and the cutting and sealing assembly is transpor-ted away from the film web leaving a new leading film edge held by the turntable clamps to begin the next wrap cycle.

Abstract: ADJUSTABLE SHEAR BAR FOR A HARVESTER            CUTTERHEAD          Abstract of the Disclosure A forage harvester has a rotary cylinder type cutterhead mounted in a housing with opposite side walls, crop material being fed into the cutterhead in a generally radial direction over a shear bar adjacent the cutterhead periphery.  The shear bar is mounted for fore and aft adjustment toward and away from the cutterhead periphery to maintain the optimum clearance between the cutterhead and the shear bar by means of a mechanism that includes a pair of bell cranks respectively pivotally mounted to support members on the opposite side walls, with one end of each bell crank being connected to the shear bar through a fore and aft link while the other end of the bell crank threadably receives the threaded portions of a vertically elongated rod that is rotatably supported adjacent the housing side wall and has an easily accessible head adjacent the top of the housing, whereby rotation of the rod causes the bell crank to rock on its pivot to cause linear fore and aft adjustment of the shear bar.  The force exerted through the adjusting mechanism is sufficient to overcome a clamping force exerted by a bolt and nut that clamps the shear bar to the supporting structure at opposite ends of the shear bar without loosening the clamping bolt.

Abstract: HYDRAULIC SYSTEM WITH UNLOADING VALVE ASSEMBLY               Abstract of the Disclosure A hydraulic system having a reservoir fed charge pump supply-ing pressurized fluid through a charge passage and a filter to the inlet of a supply pump for direction controlled fluid devices includes a reservoir connected unloading valve assembly connected to the charge passage and parallel with the filter.  The fluid devices return fluid through a return passage connected to the unloading valve assembly which maintains back pressure on the devices at charge passage pressure.  The unloading valve assembly includes an unloading valve movable in response to a predeter-mined fluid pressure at the inlet of the supply pump to unload the charge and return passage by connecting them to the reservoir.          As the devices require more fluid from the supply pump causing the pressure at the inlet of the supply pump to drop, the unload-ing valve proportionately blocks the charge and return passages from the reservoir to circulate return fluid into the charge passage.  The unloading valve assembly further includes a signal valve which responds to a predetermined pressure differential across the filter to provide a signal indicative of a clogged filter and to cause the unloading valve to connect both the charge and return passages to the reservoir in such a situation.
