Abstract: AUTO SPOUT AIMER WITH DELAY Abstract of the Disclosure A crop-receiving wagon is pivotally attached to a forage harvesting machine with a pivotal crop discharging spout.  A dual sensitivity spout-aiming control system, maintains the spout-wagon angular relationship within first and second ranges during first and second ranges, respectively, of wagon-machine angles.  A switching circuit switches the control system between its sensitivity modes in response to changes in the wagon-machine angle and includes a timer which delays the mode switching for a certain time period after a predetermined change in the wagon-machine angle.  A gate circuit cooperates with the timer to reduce the delay period upon manual positioning of the spout.

Abstract: SELF-LOCKING DIFFERENTIAL     ABSTRACT OF DISCLOSURE     A locking means fitted within a conventional automotive vehicle type differential housing assembly normally couples the wheel axles to the power rotated housing so that the axles are driven by and rotate with the housing. When either axle rotates faster than the other axle and the housing, the locking means momentarily uncouples the faster rotating axle so that it freewheels, while the other axle continues to be driven. The locking means includes a pair of axially aligned, closely spaced apart coupling rings, each of which surrounds a bushing-like hub mounted upon and axle end portion located within the housing. A diametrically arranged, drive rod of hexagonal cross-section is positioned between the rings and extends through opposite pairs of aligned V-shaped notches formed in the facing ends of the rings. The outer ends of rod are fastened to the housing for rotating therewith. The walls of the notches are parallel to, but slightly spaced from, their adjacent rod faces. Thus, when the rod rotates with the housing, it engages the notch forming walls in its rotational path to rotate the coupling rings and simultaneously wedge them outwardly apart. The coupling rings are connected to the hubs by clutches that engage when the rod moves the rings apart and disengage when the rings move inwardly towards each other. When one axle rotates faster than the housing, its coupling ring advances angularly relative to the rod to disengage its notch forming walls from the rod, which results in its ring moving inwardly towards the other ring to disengage its clutch for freewheeling until its speed returns to housing speed. A limit means keeps the rod centered within the notches when the coupling ring is angularly advanced.

The screw pitch is adju-sted in such a manner that when the material reaches the discharge port it has attained the required particle size. The type of elements which form the grinding screw is also chosen in accordance with the material to be treated and the degree of grinding to be attained.

The output  (8) of the  oscillator  (30)  is  obtained  from  the first mode  (1).   Optional injection lock can be used for greater  stability  by means  of  coupling  a  stable  a.c. reference  (9)  into the cavity  (12)  in alignment with the second  mode  (2).   Optional  electronic  frequency  tuning comprises  a  phase  or  frequency  comparator  (11)  and  a reference  a.c.  source  (13),  producing  a  d.c.  feedback signal fed to varactor diodes (10).
