Abstract: A system is provided for monitoring the operation of a press machine over a series of press running cycles. A plurality of press operating events associated with the operation of the press machine are defined. Each press operating event has a modifiable control function associated therewith. An arrangement of accelerometers measures the press machine vibrational activity associated with each press operating event that occurs during the series of press running cycles. A processor processes the vibration measurements associated with the press operating events to identify the presence of a vibration trend therein meeting a defined trending criteria. A controller is responsive to trend identification signals generated by the processor for modifying the respective control function of each press operating event which is associated with identification of the vibration trend.

Abstract: An exfoliation corrosion detection method which enables rapid detection and evaluation of hidden exfoliation corrosion on aircraft with related cost savings. Pressure exerted on the surface by the laser created plasma generates a pressure pulse or shock wave that propagates into the part. When the stress in the shock wave is above the dynamic elastic limit of the material, the surface material yields plastically. This plastic strain creates compressive residual stresses in the surface, thereby enabling detection of exfoliation corrosion, if present.

Abstract: An apparatus and method for monitoring the carry through state of a mechanical press is disclosed. Actual slide displacement curves under load conditions are continually generated for the press being monitored. Values of rebound height, rebound count, and rebound number for the press slide may then be determined and utilized as indicators of the carry through state of the press. Measured values of rebound height, rebound count, and rebound number can then be displayed and used as indicators that the energy of the slide should be increased to bring the press closer to a carry through state.

Abstract: A fuel delivery system performs a refueling operation in accordance with voice command signals audibly provided by a customer situated within a vehicle positioned for refueling. The customer generates audio signals representative of refueling transaction information, such as a request to initiate fuel dispensing activity, data indicative of the fuel type, fuel volume, purchase amount, and form of payment, and a request to terminate the refueling transaction. A microphone detects the customer voice signals and provides audio detection signals representative thereof. A speech recognition device converts the audio detection signals into corresponding fuel dispensing command signals. A controller generates fuel dispensing control signals in accordance with the fuel dispensing command signals and couples these control signals to the fuel dispenser assembly to effect operative control thereof.

Abstract: The present seal system is in two parts. First is that of an elastomer energizer, which may be in the shape of a square ring, o-ring, or an other custom design for energizing the seal system. Second is that of a seal element having a particular geometry and composition. The geometric layout of the seal element ensures firm contact between the seal and groove bottom, independently of the seal pressure and radial position of the moving part, and concentrates contact forces against the moving part by means of a seal apex. In the installed state, the seal is forced into contact with the groove bottom by having an outer diameter matching or exceeding that of the groove bottom, and a radial height exceeding that of the housing groove. Further, the influence of the compression ring or energizer is balanced out by positioning the seal apex near the axial position of the center of the energizer.
