A gas inflationevacuation system and sealing system for use with occlusive devices in vascular procedures. The pivoting mid-floor can move or adjust when a large volume of crop material is fed into the feeder house, while providing support for the conveyor chain along substantially the entire length of travel between the transverse drum and sprocket means, thus reducing the friction on the chain, and preventing the system slow downs that occurred in feeder house systems using a fixed mid-floor. A chip coordinate for chip-marking is having either 1-character or 2-characters is generated by coding a conventional coordinate of a chip in the wafer using the decimal or 62 decimal numeration system. The self-grown crystal layer is a new grown crystal structure where the seed crystal grows into a new phase through a normal diamond or cubic boron nitride synthesis process in the presence of a catalyst metal solvent. In this way, the injection molded polymeric hub structure is fused to the catheter shaft, with a unified polymeric bond, and without the use of adhesive. The arm of each actuator incorporates a protruding shield configured to restrict the flow of ink through the associated second aperture.
