Abstract: An automated transplanter has been designed for seedlings previously loaded and correctly spaced on a low tensile-strength, biodegradable tape wound on a spool. The transplanter design allowed for rapid planting of the tape with the attached seedlings while minimizing the tension placed on the tape. The design linked the unspooling of the tape directly to the ground speed of the tractor and provides for an anti-backlash mechanism to prevent the spool from free-wheeling when the tractor speed slowed quickly. Using this design, synthetic seedlings attached to a low tensile-strength tape were successfully planted at speeds up to 7.5 mph.

Abstract: A particle examination system is provided, including a surface which provs a background such that particles on or suspended above the surface are distinguishable from the background; a video camera, for producing an image of the particles against the surface; and an image processor, connected to the video camera, for digitizing the image. A computer is utilized to analyze the digitized data from the image processor, allowing various types of comparisons to be made between the particles examined and a known standard. Additionally, the invention may include a vacuum device which, through holes on the surface, holds the particles in position for examination. A transparent/translucent or transparent surface may be provided, enabling illumination from beneath such plate, allowing analysis of particles for cracks and fissures.
