Abstract: A light-enhanced wafer processing system disclosed herein which includes a rotatable chuck configured to support and selectively rotate at least one wafer, at least one dispenser body configured to selectively flow at least one photolytic material onto a surface of the wafer, and at least one optical radiation source may be configured to provide optical radiation to at least a portion of the wafer having photolytic material applied thereto, wherein the optical radiation is configured to result in the formation of optically-induced radicals having enhanced reactivity with at least one material applied to the wafer.

Abstract: It is described a rotary drilling system (10) for drilling a borehole (12) in inhomogeneous and/or hard rock formations. The system (10) comprising: a rotary drill bit (20; 50), and at least two electrodes (21, 22, 23, 51, 52, 53) arranged for pulsing between said electrodes of at least one high voltage electro pulse (41), wherein said at least one high voltage electro pulse (41) is generated in response to a detected resistance on the drill bit (20) from a rock formation (40) in front of the drill bit (20) while rotating, in order to create small/micro-cracks (45) in the rock formation (40).

Abstract: The invention concerns a process and a device for unloading a mail piece container, open at the top, with sidewalls that slant toward the outside, that is loaded with mail pieces that stand upright next to one another. According to the invention, the mail piece stack, after having been compressed, is held by holding supports that are inserted into the container and that feature driven revolving conveyor bands. While the supports are being inserted, the conveyor bands are driven in such a way that the conveyor band segments in contact with the mail piece stack are motionless with respect to the mail pieces. Next, the container is tilted by >90° along with the mail pieces and the holding supports. After the container is tilted back somewhat, a base plate is inserted and the whole ensemble is tilted back to the point where the stack stands on the horizontally positioned base plate. Then the container is removed towards the bottom.

Abstract: The stack of flat mail pieces that are arranged adjacent to one another on a support can be portioned with the aid of at least one displaceable holding support containing a conveyor belt because the support is divided into a horizontally oriented, stationary section and an adjacent section that can be pivoted about a pivoting axis positioned at the end of the pivotable section in the stacking direction. During the portioning process, the pivotable section extending downward at an angle from the stationary section is pivoted downward into a horizontal position. A holding support with a conveyor belt that is driven downward during the pivoting process is arranged underneath the stationary section at its border with the pivotable section. An additional support is arranged on the frame of the pivotable section of the support above the mail pieces. This additional support holds the stack remaining on the stationary section of the support.
