Abstract: ROUTING ARCHITECTURE FOR A MULTI-RING LOCAL AREA NETWORK                    ABSTRACT      The architecture provides a frame format and procedure for routing messages through a single ring or multi-ring communication system.  Stations associated with the exchange of messages are located on the single ring or on different rings of the multi-ring communication system.  The rings are connected by bridges to form a physical local area network.          The frame format includes a plurality of control bits positioned within a Routing Information (RI) field, a frame control field and a frame status field.  Messages are generated and structured in accordance with the frame format.          A group of the control bits, in each message, is set with initial values according to the message type.  Thus, different messages are characterized by a different sequence of control bit settings.  A routing algorithm analyzes the message and depending on the status of the control bits, the message is processed and ultimately switched to its proper destination.

Abstract: Abstract of the Disclosure:           According to the specified process chromium oxy-fluoride catalysts which have largely lost their activity are regenerated.  The catalysts are mixed with magnesium oxide or magnesium hydroxide in the presence of water and converted into a paste.  If necessary the mixture must be concentrated by evaporation until it exhibits the consis-tency of a paste.  Finally the paste is dried.  The paste is best converted into molded bodies such as, for example, granules before drying.
