Abstract: Inside-out cutter apparatus for cutting fiber tow into predetermined lengths including rotatable cylindrical member defining an axially extending passageway for receiving fiber tow therethrough and an outlet opening on periphery of cylindrical member through which fiber tow emerges onto work surface formed around periphery, work surface including at least one guide shoulder and a base surface bordering along length of guide shoulder with guide shoulder and base surface angled to position fiber tow on work surface at acute angle to axis of rotation and away from alignment with direct circumferential path leading from outlet opening, and an array of knives extending around work surface with cutting edges facing toward and spaced from work surface; and method of cutting fiber tow inside-out into predetermined lengths including steps of rotating circumferential work surface around an axis, feeding fiber tow within work surface through opening in periphery of work surface onto work surface, positioning fiber tow a

Abstract: A system for displaying data to produce a three-dimensional image, and interactively modifying and transforming the data and the resultant image in response to user commands comprises control circuitry, a high-speed processor linked to the control circuitry, a memory linked to the control circuitry and to the high-speed processor, and a raster-based display linked to the control circuitry and to the memory. The control circuitry is programmed to transfer data from the memory to the high-speed processor, to control the high-speed processor in modifying and transforming the data in response to, and in accordance with, the user command to obtain transformed data representative of a plurality of two-dimensional rasters of pixels, to transfer the transformed data from the high-speed processor to the memory, and to control the raster-based display in displaying the transformed data.
