Abstract: INDUSTRIAL CONTROL SYSTEM            ABSTRACT OF THE DISCLOSURE           A control system for controlling an industrial process includes a plurality of remotely located process control units (remotes) each coupled to an associated input/output device(s) and adapted to communicate with one another through a dual channel communications link.  Each remote has a unique success-ion number within a predetermined succession order with super-visory communication-control of the communication link sequential-ly transferred to each remote according to its succession number to provide a revolving or master for the moment control of the system.  Digital information in the form of data and control information blocks is transmitted between the remotes with the blocks transmitted twice on each channel of the communications link.  The destination remote tests the block validity on one of the two dual channels and, if validated, responds with an acknowledgement signal (ACK) and, if invalid, tests the blocks on the other, alternate channel and then responds with an acknowledgement or non acknowledgement signal (NAK) depending upon whether the data blocks tests on the alternate channel are found valid or invalid.  A non-acknowledgement from the destination remote re-triggers the transmission of the blocks from the source remote.  The system provides high overall operating efficiency since the remotes will maintain a system-like integrity on each side of a severed communication link and the redundant block transmission with alternate line checking provides very high information transfer reliability.

Abstract: Abstract of the Disclosure A token-passing, ring-based data com-munications network provides a distributive method and apparatus for detecting and regenerating a lost token. The method includes, after detection of the loss of the token, transmitting at a detecting node a data packet not including a token, the data packet uniquely iden-tifying the transmitting node as the data source. Simultaneously, the transmitting node, after transmitting the tokenless data packet, strips all incoming data from the network.  If the transmitted packet is successfully received by the transmitting node, a new token is generated by the node.  If the packet is not received, the node defers to an arbitra-tion method which includes delaying a next data packet transmission for a probabilistically determined period of time.  The mean time upon which the probabilistic approach is based increases with each unsuccessful data packet transmission attempt.

Abstract: ABSTRACT OF THE DISCLOSURE    Ready-to-eat  shredded  potato  products  having  a pleasant texture, and a substantially uniform off-white to golden tan color, are obtained by the process of the present invention.  A potato dough is formed under low temperature and low shear mixing conditions so as to avoid  overgelatinization  of  the  potato  starch  and tackiness  which  would  impede  flowability  and  the continuous production of long continuous shred layers.          Individual  discrete  dough  pieces  having  a  moisture content of from about 29% to about 50% by weight are tempered to distribute the water substantially uniformly throughout the dough pieces, the tempered dough pieces are  shredded  and  the  shredded  dough  is  cooked.          Producing  substantially  homogeneous  discrete  dough pieces without first producing a dough mass is achieved by spraying a premix of the dry ingredients with water as  the ingredients are tumbled to form agglomerates.          Tempering is necessary to obtain continuous flowability of the dough pieces into and through feed hoppers and the shredding rolls over extended periods of time.  The shredded potato products can be cooked by frying or by baking.  The dough is formed from at least one potato starch source which is pregelatinized or precooked and in comminuted or particulate form.   Cooking of the pregelatinized or precooked at least one potato starch source  in  the  presence  of  water  is  not  performed until after the shredded product is formed. This avoids overgelatinization  and  tackiness  which  would  impair flowability   to  and  through  the  shredding  mills.          Shredded potato products made from at least one potato starch source and cereal grains can be made by admixing a pregelatinized or ungelatinized cereal grain with at least one potato starch source.
