Abstract: A method for the plasma treatment of parts. The method includes sending loading signals from an electronic control to a transfer mechanism and loading the parts from a position outside of the treatment chamber to a plurality of treatment positions within the treatment chamber based on the loading signals. A plasma is generated within the treatment chamber to treat the parts. After treatment, unloading signals are sent from the electronic control to the transfer mechanism and the parts are unloaded from the treatment chamber based on the unloading signals. Each of the parts may be guided to a corresponding one of the treatment positions during loading.

Abstract: A system for the plasma treatment of parts. The system includes a chamber base sealingly engageable with a reaction chamber to form a treatment chamber and a lifting device operable to lift the reaction chamber from the chamber base. A transfer mechanism is operable to transfer parts along a guide to multiple treatment positions within the treatment chamber when the reaction chamber is disengaged from the chamber base. An electronic control system controls the transfer mechanism for transferring the plurality of parts to the treatment positions. The parts are treated with a plasma produced within the treatment chamber by a plasma-generating device.

Abstract: Methods and apparatus for plasma treatment of workpieces in which the apparatus includes a reaction chamber having a door through which a magazine loaded with workpieces and an empty magazine can be manually or robotically placed on a shelf in the reaction chamber, and associated apparatus for striking and maintaining a plasma in the reaction chamber, the shelf being provided with stops for maintaining both magazines in alignment so that the workpieces can be pushed out of the loaded magazine, across a gap between the magazines, and into the empty magazine while plasma exists in the gap, and pushing apparatus for pushing workpieces from the loaded magazine, across the gap, and into the empty magazine, and the method of plasma treatment carried out by this apparatus. In one version the pushing apparatus pushes all of the workpieces from magazine to magazine at once. In another version, a subplurality of the workpieces in the loaded magazine is pushed across the gap and into the empty magazine at one time.

Abstract: The application of certain sulfonylurea compounds to sugarcane and sorghum increases their sugar content. These compounds have the formula: ##STR1## wherein R is C.sub.1 -C.sub.4 alkyl, C.sub.3 -C.sub.4 alkenyl, CH.sub.2 CH.sub.2 OCH.sub.3 or CH.sub.2 CH.sub.2 Cl;R.sub.1 is H or CH.sub.3 ;X is CH.sub.3, OCH.sub.3, OC.sub.2 H.sub.5 or CH.sub.2 OCH.sub.3 ;Y is CH.sub.3 or OCH.sub.3 ; andZ is CH or N; oran agriculturally acceptable salt thereof.
