Abstract: Aspects of a turn conveyor system are described. In one embodiment, the system includes a first conveyor and a second conveyor, where the first conveyor includes a lateral displacement mechanism configured to displace an article laterally between the first conveyor and the second conveyor. The system also includes a lateral conveyor extending between the first conveyor and the second conveyor, a sensor configured to sense a position of an article on the first conveyor, an arm positioner configured to position a turn arm to one of a plurality of locations, and control logic. The control arm can be configured to control an operation of the arm positioner to position the turn arm for rotation of the article, and control an operation of the lateral displacement mechanism based in part on the position of the article to displace the article onto the lateral conveyor and into the turn arm.

Abstract: Aspects of a turn conveyor system are described. In one embodiment, the turn conveyor system includes a first conveyor, a second conveyor adjacent to the first conveyor, a lateral conveyor extending between the first conveyor and the second conveyor, and a turn arm. The turn arm may extend across the second conveyor and be coupled to the second conveyor at a position corresponding to an end of the lateral conveyor. In one embodiment, the turn arm includes an extension bar, a rolling bumper having an angular degree of freedom, and an extension down shaft. According to various aspects, the turn conveyor system may displace an article in a first direction with the first conveyor, laterally displace the article in a second direction onto the lateral conveyor, laterally convey the article toward the turn arm, and rotate the article from a first orientation to a second orientation using the turn arm.

Abstract: A laser ablation nozzle including a main pressure chamber centered on an area of a substrate to be ablated and arranged to push a stream of gas through the main pressure chamber onto the substrate. A vacuum chamber surrounds the main pressure chamber and is arranged to vacuum away the process gas and ablation debris. To attempt to address uneven pressure and flow, flow restrictors can be provided at one or both of the process gas inlet and the vacuum chamber. The vacuum flow restrictor is intended to create constriction in a channel to generate a uniform vacuum induced flow around substantially the entire circumference of the nozzle opening. Similarly, the process gas flow restrictor is intended to generate substantially uniform gas flow into the main pressure chamber.
