    Abstract: Systems and methods of accessing a database associated with a process control system send a request for information from a client application to an intermediate data server process and determine if the information is stored within a data source associated with the intermediate data server process. The systems and methods also send a request for the information from the intermediate data server process to another process if the information is not stored within the data source and access the database to retrieve the information subsequent to the other process receiving the request for the information.

    Abstract: Smart graphic elements are provided for use as portions or components of one or more graphic displays, which may be executed in a process plant to display information to users about the process plant environment, such as the current state of devices within the process plant. Each of the graphic elements is an executable object that includes a property or a variable that may be bound to an associated process entity, like a field device, and that includes multiple visualizations, each of which may be used to graphically depict the associated process entity on a user interface when the graphic element is executed as part of the graphic display. Any of the graphic element visualizations may be used in any particular graphic display and the same graphic display may use different ones of the visualizations at different times. The different visualizations associated with a graphic element make the graphic element more versatile, at they allow the same graphic element to be used in different displays using different graphical styles or norms. These visualizations also enable the same graphic element to be used in displays designed for different types of display devices, such as display devices having large display screens, standard computer screens and very small display screens, such as PDA and telephone display screens.

    Abstract: The high speed depositor allows the manufacturing plant, e.g., a modern large bakery, to double the production of the batter, filling and icing lines. The depositor is comprised of a food quality positive displacement pump, a high torque stepping motor, a microprocessor based controller and a depositing manifold with individual valves. Other supporting apparatus, which are inputs and outputs of the controller, include a rotary encoder to measure the degrees of revolution of the pump, an air solenoid valve to apply air (motive force) to the stepping motor and an on/off switch to start and stop the depositing operation. Each nozzle on the depositing manifold has a flow control device to equalize the flow and therefore each cup weight of product deposited into the baking pan. A feed tank or hopper supplies a constant flow of product to the suction of the depositor pump. The manifold is typically mounted a few inches above a conveyor which carries baking pans underneath the manifold nozzles. The columns of baking pan cups pass directly underneath the nozzles and the product configuration downloaded to the depositor controller causes it to make accurate deposits into each cup in each row. The stepping motor causes the pump to turn the exact degrees of revolution necessary to deliver the desired cup weight into each of the baking pan cups.

    Abstract: A means and method of controlling the muzzle velocity of a gun launched projectile to ensure that the muzzle velocities of several rounds of the same type tend towards the same value or that of an individual round approaches some nominal value. A sensor means measures a parameter related to the muzzle velocity of a projectile and a control means instructs an electrothermal energy unit to discharge a fixed amount of energy into the gun barrel after a certain time delay, the time delay being derived from the measured parameter and being such to ensure that discharge causes the projectile to achieve a controlled muzzle velocity.
