THE virtual elimination of relay contacts from the highly repetitive functions required for automatic warehousing was made possible by the selection of static control elements, Westing-house Cypak,1,2,3 in place of conventional relays for an extensive mechanized carton-handling installation in the Chelsea Milling Company premix food plant at Chelsea, Mich. While the basic concept of the control philosophy was determined to be the same for either relays or static control elements, the high reliability and negligible maintenance inherent in static control elements, which have no moving parts subject to wear or corrosion, dictated the choice. Interestingly, the first cost was found essentially comparable.
