Abstract: The present invention discloses an improved insert machine for inserting flat material into an open pocket and, more particularly, to a straight line insert machine employed for printed matter such as newspapers. The machine includes an all-electronic control system for controlling machine functions. The control system includes at least one central control computer running under software control and a plurality of network controllers, all coupled together via a controller area network (CAN) bus. Electronic control messages for controlling machine elements are sent among the computers and controllers using a novel message protocol to enable both broadcast messages and individual messages to be employed.

Abstract: In a multi-processor system which utilizes store-in-cache techniques, a queueing mechanism for insuring that all units that wish to interrogate a memory line will be permitted to interrogate the line. Backing store access requests for data that is contained in the cache of another processor are queued until they can be serviced. The access requests that pertain to particular data are issued from the queue on a first-in-first-out basis. No group of interrogating units will be able to lock out another unit that wishes to interrogate.
