ABSTRACT:
A universal logic body block includes a number of identical cavities having accompanying passageways of identical number and pattern. Each single cavity forms the basic housing for installation of various valve components which may perform a desired logic function AND, MEM, DIF, OR, NOT or TIM. A primary universal insert fitted within an above-described cavity of the universal logic body block in combinaton with various other valve elements will provide an AND, MEMORY, DIFFERENTIATOR or NOT logic function. A universal valve member may be fitted within a cavity in a first manner in combination with other components, to provide the logic functions, NOT and DIFF. The universal valve member may be fitted within a cavity in a second manner in combination with other components to provide the logic functions AND and MEMORY. Additional specialized inserts are provided for insertion into a cavity of the universal logic body block in combination with various valve elements to provide the TIM logic function or the OR function. Various logic circuits can be formed in one block by means of connections between separate logic devices.
