The generation of global fields of terrestrial biophysical parameters from the NDVI

A coke oven leveling door hatch construction, comprises a hatch pivot bearing adapted to be mounted on the coke oven door or directly adjacent the door. A hatch door for closing a leveling port includes a locking bar extending across the front face thereof which terminates in a forked end having a pair of bearings which engage over the respective ends of the hatch pivot bearing and which are secured to a pivot which extends through the pivot bearing so that the door may be pivoted thereabout. The pivot includes an offset portion or crank arm which is connectable to an opening mechanism which comprises a fluid pressure operated cylinder having a movable piston therein which is connected to a rotatable forked arm which engages the crank to rotate it through an arc to effect turning of the door to open the door. The locking bar includes an inwardly extending portion on the side of the door opposite from the pivot, which terminates in a hook which is engageable by a rotatable arm having a detent which engages with the hook. The arm is biased by a spring to rotate in a direction to cause engagement but the locking bar may be moved against the biasing force to rotate the latching arm having the detent so that the detent moves out of engagement with the hook.
