Title: Neural network/expert system process control system and method
Inventor: SKEIRIK RICHARD D
IPC: G05B13/02
Filed: 1991-07-25
Granted: 2002-02-26
Abstract: A neural network/expert system process control system and method combines the decision-making capabilities of expert systems with the predictive capabilities of neural networks for improved pro-cess control. Neural networks provide predictions of measurements which are difficult to make, or supervisory or regulatory control changes which are difficult to implement using classical control tech-niques. Expert systems make decisions automatically based on knowledge which is well-known and can be expressed in rules or other knowledge representation forms. Sensor and laboratory data is effectively used. In one approach, the output data from the neural network can be used by the controller in controlling the process, and the expert system can make a decision using sensor or lab data to control the controller(s). In another approach, the output data of the neural network can be used by the expert system in making its deci-sion, and control of the process carried out using lab or sensor data.      In another approach, the output data can be used both to control the process and to make decisions.

Title: Structures and processes for fabricating field emission cathodes
IPC: H01J1/304
Filed: 1990-10-17
Granted: 1999-03-09
Abstract: The present invention relates generally to new structures for a field emission cathode and processes for fabricating the same. The field emission is made of any material that is capable of emitting electrons under the influence of an electrical potential. A process for making one embodiment of the invention includes the steps of forming a hole (15) in a substrate (5), depositing a first material (20) in said hole to form a cusp (21), depositing an electron emitting material (30) to fill at least partly said cusp and removing the first material to expose a portion (31) of the electron emitting material. The field emission cathode has several unique three dimensional structures. The basic structure comprises a layer of material with cathode tips. For a more complex structure the cathode tip is preferably accurately aligned inside an extraction/control electrode structure, in preferably a vacuum environment. The structures of this invention can be fabricated to be connected to other similar field emission cathodes or to other electronic devices.

Title: Apparatus for cooling calender rolls and the like
Inventor: CONRAD HANS-ROLF
IPC: D21G1/00
Filed: 1993-01-26
Granted: 1996-02-27
Abstract: Apparatus  for cooling the  end portions of  a calender roll which has an elastic layer adjacent its peripheral surface and wherein the central portion of the peripheral surface is overlapped by a running web of paper or other material when the calender is in use.  The width of the non-overlapped portions of the peripheral surface of the roll varies when a web having a first width is followed by a web having a different second width.  This could lead to damage to the roll at the non-overlapped portions of the peripheral  surface  as  a  result  of  overheating  by  an adjacent  rotary  component  of  the  calender.    The  end portions of the roll are cooled by discrete adjustable cooling devices which are movable along the respective non-overlapped  portions  of  the  peripheral  surface  in parallelism with the axis of the roll and each of which shares movements with a monitoring device which is to be maintained in a selected position relative to the adjacent marginal portion of a running web.   To this end,  the monitoring devices transmit signals to discrete reversible motors  which  move  the  monitoring  devices  along  the respective  non-overlapped  portions  of  the  peripheral surface and are brought to a halt when the monitoring devices assume their selected positions.

Filed: 1993-04-27
Granted: 1996-08-06
Abstract: A die for use with a conventional punch to mechanically join, or clinch, two or more sheets of metal or other suitably formable material. The die is specially formed with a cavity having one or more lateral passages extending from the periphery of the cavity.  When the sheets are positioned against the die and impacted by a suitable punch, the lateral passages permit the lateral extrusion of a quantity of sheet material which serves to mechanically interlock the sheets.  The die has no moving parts itself, providing an economical design which is adaptable to various types of presses and applications.   Moreover, the lateral passages can accommodate sheet material of various thicknesses and yet create a sufficient clinching effect without the need to closely calibrate the punch or press used with the die.

Patent CA-2100832-C (CA)
Inventor: CHANDLEY GEORGE DIXON
IPC: B22D27/04
Filed: 1993-07-19
Granted: 1999-11-02
Abstract: The present invention involves a method and apparatus for making an intermetallic casting (e.g. a titanium, nickel, iron, etc. aluminide casting) wherein a charge of a solid first metal protected from air as required is disposed in a vessel, and a charge of a second metal that reacts exothermically with the first metal is melted in another vessel. The molten second metal is introduced to the vessel containing the charge of the first metal so as to contact the first metal.      The first and second metals are heated in the vessel to exothermically react them and form a melt for gravity or countergravity casting into a mold. The exothermic reaction between the first and second metals releases substantial heat that reduces the time needed to obtain a melt ready for casting into a mold. In particular, the exothermic reaction between the first and second metals, in effect, reduces the residence time of the intermetallic melt in the vessel. This reduced residence time, in turn, reduces potential contamination of the melt by reaction with the vessel material. Moreover, the energy requirements needed to heat and melt the metals in the vessel are considerably reduced. Low cost forms of the first and second metals can be used in practicing the invention. As a result, overall casting costs are reduced. The method and apparatus of the invention can be used to produce large numbers of low cost, low contamination intermetallic castings as needed by the automobile, aerospace, and other industries.

IPC: G01R27/28
Filed: 1995-03-02
Granted: 1999-05-18
Abstract: A method for measuring transmission parameters of a balanced pair utilizes a unbalanced type equipment which is widely used, rather than balanced type equipment which is not in practical use.   In the measurement, the balanced pair is connected  to  the  unbalanced  type  equipment,  or  via  an unbalanced / balanced type transformer thereto at the measuring end.  Predetermined terminated states are set at the measuring and far-ends to measure input admittances dependent on the terminated  states.     A  characteristic  impedance  and  a propagation  constant  for  the  transmission  parameters  are calculated from predetermined equations into which the measured input admittances are substituted.
