20100181703 | BYPASS COOLING REDUCTION ON HIGH PRESSURE DIE CAST MACHINES - Within an improved method of maintaining a die during interruptions in production and of subsequently returning the die to an optimal operating temperature, instead of having a manual control valve in the bypass loop of cooling medium, a PLC controlled valve is provided which can automatically allow or stop the flowrate through the bypass loop. Instead of circulating cooling medium through the die continuously, and at a reduced rate, during the interruption, the cooling medium is not circulated at all initially during the interruption. When the restart of production is desired, the first two preheat shots produced are made without the circulation of any cooling medium through the die. The valve within the bypass loop is then opened to let some cooling medium circulate through the die, however the circulation rate is less than the rate associated with normal production. The bypass loop is then left open while the valve in the primary loop is reopened. | 07-22-2010 |
20130025559 | HIGH PRESSURE DIE CASTING FLASH CONTAINMENT SYSTEM - Devices for sealing the gap between a bore pin and an insert (e.g., sleeve) during the casting of, for example, internal combustion engine cylinder blocks. Such devices incorporate a sealing ring set that may be set into a recessed channel about a circumference of the bore pin. Radial force on the ring provides a seal between the bore pin and the sleeve that prevents flash from entering gaps therebetween. The ring may take on any of a number of different configurations and the outward force may be generated in various ways—including from the tension of the ring itself. | 01-31-2013 |
20150343520 | CYLINDER HEAD CASTING APPARATUS AND METHODS - A casting apparatus for forming a cylinder head. The apparatus is configured to inhibit gate stick by promoting top-down directional solidification of molten metal in the mold cavity by any one or more of specific placement of gate pins in relation to apertures used to deliver molten metal to the mold cavity, circulating a cooling medium through the gate pins in a parallel fashion, configuring the gates so that a volume on the lower side of the gate is larger than a volume on the upper side of the gate, and insulating the inside surfaces of feeder lids and feeder bowls. | 12-03-2015 |

20080288089 | METHODS AND SYSTEMS FOR BATCH PROCESSING AND EXECUTION IN A PROCESS SYSTEM - A system and method for implementing a control process within a process control system and resolving inconsistencies during execution of the control process includes loading the logical structure of the control process, loading a plurality of instantiation objects or processes when the control process is instantiated, using the instantiation objects to instantiate a procedural element of the control process as the control process calls for the procedural element during execution, executing the procedural element as part of the control process, and deconstructing the procedural element as execution of the procedural element is completed during execution of the control process. Resolution of inconsistencies includes executing a first model of an entity in a controller, executing a second model of the entity in an execution engine, detecting a difference between the models, generating a prompt and receiving an operation instruction to continue the process or abort the process. | 11-20-2008 |
20090082894 | Online Recipe Synchronization in a Real-Time Batch Executive Environment - A method of executing a batch process in a manufacturing environment according to a product recipe, such that the product recipe specifies a plurality of actions and a plurality of parameters, includes performing at least one action of the batch process corresponding to a first version of the product recipe, receiving a second version of the product recipe, such that the second version of the product recipe is distinct from the first version of the product recipe, suspending the execution of the batch process prior to completion of the batch process, and resuming the execution of the batch process according to the second version of the product recipe. | 03-26-2009 |
20090112335 | METHOD AND APPARATUS FOR INTELLIGENT CONTROL AND MONITORING IN A PROCESS CONTROL SYSTEM - A controller includes a control module to control operation of a process in response to control data, a plug-in module coupled to the control module as a non-layered, integrated extension thereof, and a model identification engine. The plug-in detects a change in the control data, and a collects the control data and data in connection with a condition of the process in response to the detected change. The model identification engine executes a plurality of model parameter identification cycles. Each cycle includes simulations of the process each having different simulation parameter values and each using the control data as an input, an estimation error calculation for each simulation based on an output of the simulation and based on the operating condition data, and a calculation of a model parameter value based on the estimation errors and simulation parameter values used in the simulation corresponding to each of the estimation errors. | 04-30-2009 |
20100087935 | COMPLETE INTEGRATION OF STAND-ALONE BATCH OPERATOR INTERFACE CAPABILITIES INTO GENERIC HUMAN MACHINE INTERFACE USING COMPONENTIZED OBJECTS - Systems and methods for providing an integrated HMI application for monitoring and interacting with both batch and non-batch processes in a process plant are disclosed. A plurality of independent stand-alone software objects defining various batch process interface views are embedded within a non-batch process control interface application. A blackboard service is provided for storing batch control data used by the various stand alone software objects. The blackboard service may be adapted to communicate with a batch control server to receive batch control data for populating the various batch interface views with data relating to various batch processes being carried out in the process plant and to send instructions for controlling the various batches input by users via the various batch interface views. When executed by a processor, the stand alone software objects defining the various batch interface views read data from and write data to the blackboard service to communicate data between batch process interface views and preserve contextual information between interface views to allow efficient and intuitive navigation between batch process interface views. | 04-08-2010 |
