Abstract: A system and method for stacking two bulk bags one on top of the other on a pallet, the method comprising controlling a pallet feeder into providing a pallet; filling a first bag with a first amount of product on the pallet and sealing the first bag; filling a second bag with a second amount of product, and depositing the second bag filled with the second amount of product on top of the first bag on the pallet; and straightening the bags on the pallet; wherein these steps of controlling, filling the first and second bags, and straightening are controlled by a programmable controller, the programmable controller selecting the first amount to be fed to the first bag supported by the pallet and, selecting the second amount to be fed to the second bag.

Abstract: A simulator is used with an optical locking device such as a cinetheodolite to provide inexpensive, convenient operator training. The simulator has a video monitor mounted on the viewer of the theodolite to display simulation images to an operator. A television camera mounted on the main telescope of the theodolite feeds a background image to the monitor. A graphics generator superimposes a target image on the background image. The movement of the telescope is coordinated with the movement of the target image on the monitor to provide a realistic simulation.

Abstract: A staging fixture for holding a single vane nozzle assembly in a predetermined position enables characterization of the effective throat area of the nozzle assembly. The fixture has a holding element for supporting the assembly in a central position, mechanical structure for locating the assembly in the holding element, a first reference surface structure having a first reference surface in opposed juxtaposition to the central position, and a second reference surface structure having a second reference surface in opposed juxtaposition to the central position and on a side opposite to that of the first reference surface. Open area measurements made with a standard reference vane element provide alignment or calibration measurements whereby leading and trailing "half areas" of a single vane airfoil assembly can be determined.
