    摘要： Described is a circuit modifier, network, and method for use with an event-driven digital logic simulator for enforcing consistent evaluation of input pin changes at state elements. The invention automatically interposes a fictitious 0-delay defer agent or processor, at the input pin to state elements such as D Flip-Flops. The interposition of the defer agent is handled by the simulator as follows. Defer agents schedule events related to input state changes on a special time or task queue which is not processed until after all other events have been executed for the current time, including any extra iterations caused by 0-delay scheduling activity. Defer agents or processors are placed in a simulation network just prior to one or more of the input pins of state elements, the effect of which is to delay events that normally would propagate to the input pin of a state element until all other normal simulation events are processed. Once the normal simulation events have been executed, the defer events are executed which permits the inputs of the state elements to change after other simulation events have been executed, thereby ensuring consistent evaluation of pin changes at state elements.

    摘要： A transfer network interface module provides a communication link between a data communications network bus connecting a plurality of processor based devices and a redundant processing system. The redundant processor system has first and second processor based devices communicatively coupled to at least one other remote based device by means of the data communication network. The first processor based device operates on an active status and the second processor based device operates on a backup status until a switch occurs. The switch causes the second processor based device to begin operation on active status. The transfer network interface device is communicatively disposed between the first and second processor based devices and the data communications network and permits continuous communication between either of the first and second processor based devices and the remote processor based device regardless of which of the first and second processor based devices is on active status. Each transfer network interface module has a thumbmwheel switch for setting a unique address and a mutually common address on the data communications network.

    摘要： An apparatus for removing vanadium from phosphoric acid includes a precipitator that receives vanadium-containing process-feed phosphoric acid and adds an oxidant to the process-feed phosphoric acid, whereupon precipitates containing phosphorus and vanadium are formed in a phosphoric acid filter feed slurry. The solid precipitate is removed by a filter. The filtrate, after optional further oxidation, is contacted to an ion exchange resin to remove additional vanadium from the filtrate to produce a phosphoric acid product of reduced vanadium content. A first portion of the phosphoric acid product is removed from the apparatus for further use. A reducing agent is added to a second portion of the phosphoric acid product, and the reduced acid is used to strip vanadium from the loaded ion exchange resin. The vanadium-loaded second portion of the phosphoric acid is mixed with fresh phosphoric acid and fed to the precipitator. The phosphoric acid in the precipitator has a phosphate content of from about 40-45 percent, and at least a portion of the phosphoric acid in the precipitator is produced by diluting more concentrated phosphoric acid to the 40-45 percent phosphate range.
