Abstract: Bioplastic compositions and methods of making are described herein. The various mechanical and physical properties of the bioplastic may be varied by altering the thermoforming or incorporating an additive depending on the desired mechanical and physical properties of the end product. The bioplastic may be made entirely of biomatter and be backyard compostable.

Abstract: The present invention involves reduction of exhaust emissions through the use of a catalytic converter which has at least one sensor disposed between two or more beds of solid catalysts, or mid-bed, and which does not include an external heat shield.

Abstract: A method of determining the coincidence of a subject area and a clip area in a graphic display system, comprising creating three parts list, one for parts of the subject area that are outside the clip area, a second for parts of the clip area that are inside the subject area and a third for overlapping lines. The parts of the subject area which lie outside the clip area are defined by examining the parts lists. The output can then be used to control a pen plotter, in which different colors are used so that underlying areas do not have to be linked over with overlay colors.
