Abstract: The present invention is a system and method for improved processing of flow data signals to provide output flow data signals which better approximate the true flows being measured. The general approach on which the invention is based is commonly known as flow data reconciliation. A dynamic simulation is run in parallel with a flow data reconciliation, and model predicted flows are used to complete balances wherever sensor measurements are unavailable. Model predicted compositions are also used to allow the computation of stream enthalpies so that enthalpy balances can be used in the reconciliation. The use of model predicted values of changes in inventory allow dynamic material balances to be used, making the reconciliation much more effective for processes with slow dynamic behavior. Weighting factors on sensors, computed based on the current value of the error of the sensor, reduce the impact of sensors with high errors.

Abstract: The present invention relates to an improved catalyst for the selective synthesis of monomethylamine (MMA) and dimethylamine (DMA) at the expense of trimethylamine (TMA) for a starting feed of methanol and/or dimethyl ether and ammonia. The current industrial catalyst for this process is a standard SiO.sub.2 /Al.sub.2 O.sub.3 material. The present invention combines this standard catalyst with microporous carbon molecular sieves (CMS) to form a composite material (i.e., a CMS/SiO.sub.2 /Al.sub.2 O.sub.3 material) with higher selectivity for the desired products MMA and DMA. The invention also relates to methods of making the improved catalyst and a process of using the improved catalyst material in the production of MMA and DMA.

Abstract: An on-line training neural network for process control system and method trains by retrieving training sets from the stream of process data. The neural network detects the availability of new training data, and constructs a training set by retrieving the corresponding input data. The neural network is trained using the training set. Over time, many training sets are presented to the neural network.When multiple presentations are needed to effectively train, a buffer of training sets is filled and updated as new training data becomes available. The size of the buffer is selected in accordance with the training needs of the neural network. Once the buffer is full, a new training set bumps the oldest training set off the top of the buffer stack. The training sets in the buffer stack can be presented one or more times each time a new training set is constructed.

Abstract: The present invention is a system and method for improving stream composition and/or product property estimates from process models, which better reflect the true conditions of the process. One or more process simulation models are run on a computer in parallel with the actual process to provide estimates of stream composition and/or product properties to be used to control the process. Adjustments are made to the models to maintain them in alignment with continuously measured key process variables that are closely related to stream composition and/or product properties where such a relationship exists. This greatly improves the ability of the model to track the actual process. Additional adjustments are made to both the models and to the model estimates based on differences between measured and calculated stream composition/product properties.

Abstract: A power port terminal formed by stamping from a blank of conductive material comprises a contact receiving socket portion and an integral mounting portion. The socket includes a web with a plurality of beams thereon. Each of the beams has a curved surface with a bend therein. The inner surface of the beams on the bends thereof define a substantially continuous cylindrical contact surface at a predetermined point along the reference axis of the terminal. The contact surface has a predetermined constricted dimension measured in a plane perpendicular to the reference axis, this dimension being the most constricted dimension along the reference axis of the terminal. The terminal is thereby able to accommodate a pin of any desired axial length. The trailing mounting portion has a set of mounting legs thereon that, the preferred instance, extend generally perpendicular to the reference axis of the terminal. Latch tabs may be provided one or more of the beams.

Abstract: Apparatus and method for operating the apparatus is disclosed for transferring reclaimed refrigerant from multiple recovery cylinders to a larger shipping cylinder using a vapor compressor and four-way valve to first transfer liquid refrigerant and then vapor to the shipping cylinder. This system includes flexible hoses for liquid and vapor transfer and employs valves near the couplings for connections of the hoses to the cylinders. Operating methods then permit transfer from successive cylinders to the shipping cylinders and change-outs in the shipping cylinders without loss of significant refrigerant to the atmosphere, and without inclusion of air into the refrigerant in the shipping cylinder.

Abstract: A retention system for retaining a connector housing to a substrate includes a pair of slotted arms extending from the housing and a wedge-shaped abutment member having a camming surface and a latching surface thereon. One leg of an L-shaped clip is insertable into a channel defined by the slotted arms. The top edge of this leg of the clip is notched to form a tab. The clip is deflectable by the camming surface as the leg advances into the channel until the latch bar on the clip snaps into latching engagement with the latching surface on the abutment member, thereby to secure the clip to the housing.The second leg of the clip is bent to underlie the connector housing when the clip is attached thereto.

Abstract: A computer neural network process measurement and control system and method uses real-time output data from a neural network to replace a sensor or laboratory input to a controller. The neural network can use readily available, inexpensive and reliable measurements from sensors as inputs, and produce predicted values of product properties as output data for input to the controller. The system and method overcome process deadtime, measurement deadtime, infrequent measurements, and measurement variability in laboratory data, thus providing improved control. An historical database can be used to provide a history of sensor and laboratory measurements to the neural network. The neural network can detect the appearance of new laboratory measurements in the history and automatically initiate retraining, on-line and in real-time. The system and method can use either a regulatory controller or a supervisory control architecture.

Abstract: A system and method stores fonts and generates characters. Instead of the fonts containing bit maps, the storage area (116) for each character contains the addresses (GPCR Addresses) of instructions to be used to form the character, and the required parameters for those instructions. In a preferred embodiment, a lookup table (114) for the font contains, for each character, the address of the code to start executing and details of how much more information is stored for this character and where to find it. For each character, the stored information includes addresses of microcode instructions (126) followed by the required number of parameters to define the actions necessary for character generation.
