Abstract: A system and composition for imprinting and removing high resolution images onto natural or artificial lawns and fields, covered areas such as sports fields, and landscapes, using a foaming carrier composition which enhances the functional performance of liquids containing special active agents to accomplish specific tasks such as marking and painting. The foaming carrier composition can be a solution of one or more active agents for painting, cleaning, lubricating, fertilizing, and effervescing various surfaces including athletic fields.

Abstract: High resolution images are imprinted onto precise and consistent lawns and fields by use in combination of a global positioning system; a processor for generating a desired pattern which is translated into patterning instructions; and a patterning implement which is used for generating detailed patterns and for imprinting said patterns on any of natural or artificial lawns and fields, covered areas, and landscapes.

Abstract: A method and apparatus for imprinting high resolution images onto fields, such as sports fields and landscapes is disclosed. In one embodiment, precise and consistent lawn and field patterning is accomplished by use in combination of a global positioning system; a processor for generating a desired pattern which is translated into patterning instructions; and a patterning implement which is used for generating detailed patterns and for imprinting said patterns on any of natural or artificial lawns and fields, covered areas, and landscapes. The patterning implement comprises a plurality of independent printing mechanisms incorporated within said patterning implement, each of the independent printing mechanisms coupled to receive patterning instructions from the processor and operate selectively in response thereto.

Abstract: A saw having a self-pumped hydrodynamic blade guide or bearing for retaining the saw blade in a centered position in the saw kerf (width of cut made by the saw). The hydrodynamic blade guide or bearing utilizes pockets or grooves incorporated into the sides of the blade. The saw kerf in the workpiece provides the guide or bearing stator surface. Both sides of the blade entrain cutting fluid as the blade enters the kerf in the workpiece, and the trapped fluid provides pressure between the blade and the workpiece as an inverse function of the gap between the blade surface and the workpiece surface. If the blade wanders from the center of the kerf, then one gap will increase and one gap will decrease and the consequent pressure difference between the two sides of the blade will cause the blade to re-center itself in the kerf.

Abstract: A reusable grinding tool consisting of a replaceable single layer of abrasive particles intimately bonded to a precisely configured tool substrate, and a process for manufacturing the grinding tool. The tool substrate may be ceramic or metal and the abrasive particles are preferably diamond, but may be cubic boron nitride. The manufacturing process involves: coating a configured tool substrate with layers of metals, such as titanium, copper and titanium, by physical vapor deposition (PVD); applying the abrasive particles to the coated surface by a slurry technique; and brazing the abrasive particles to the tool substrate by alloying the metal layers. The precision control of the composition and thickness of the metal layers enables the bonding of a single layer or several layers of micron size abrasive particles to the tool surface.
