Abstract: A vector processing computer is configured to operate in a pipelined fashion wherein each of the functional units is essentially independent and is designed to carry out its operational function in the fastest possible manner. Vector elements are transmitted from memory, either main memory, a physical cache unit or a logical cache through a source bus where the elements are alternately loaded into the vector processing units. The vector control unit decodes the vector instructions and generates the required control commands for operating the registers and logical units within the vector processing units. Thus, the vector processing units essentially work in parallel to double the processing rate. The resulting vectors are transmitted through a destination bus to either the physical cache unit, the main memory, the logical cache or to an input/output processor.

Abstract: In an apparatus for separating particulate material of a selected size from particulate material of a smaller size, there is provided a screen assembly having a screen element for separating the particulate material. A tray assembly loosely supports impact elements in close relationship to the screen to dislodge particulate material from the apertures of the screen upon impact during operation of the apparatus which agitates the screen and tray assembly. The screen element and the tray assembly form an enclosure for the impact elements. The screen assembly and tray assembly are intermeshed and independently supported from one another and are adapted to separate upon removal from the apparatus.
