  • Patent number: 6360212
    Abstract: In a process for designing a fuzzy regulator with at least one input parameter and at least one output parameter (x1, x2, y), where an incomplete rule base with rules that are defined explicitly is supplemented by an implicit rule whose conditional part yields a truth value that has its greatest value when the explicit rules yield a truth value of 0 and is the smallest when the explicit rules have a truth value of 1, the truth value of the implicit rule may be determined by forming the maximum from the truth values of the explicit rules and calculating the complement to 1. This leads to a great simplification of the design of the regulator and prevents instabilities that can occur with an incomplete rule base.

  • Patent number: 6319435
    Abstract: A method for the production monitoring with the manufacture of tablets in a rotary tabletting machine, with a row of upper and lower punches arranged in pairs, which cooperate with matrix bores, in which for each punch pair the maximum of the pressing force is measured, via a preselected number of readings (measuring row) an actual mean value is computed and compared to a nominal mean value and the supply of material to the individual matrix bores (filling degree) is changed when the deviation exceeds a predetermined measure, wherein before forming the mean value those pressing force readings of each measuring row, which significantly deviate with respect to other readings, are eliminated (freak value test).

  • Patent number: 6074584
    Abstract: A method for manufacturing pressed parts from hard metal, ceramic, sintered metal or likewise, in which a part of a charge of a powder-like or granular original material is filled into a pressing mould and is pressed with at least one pressing stamp against a counter surface, wherein the force and the distance of the pressing stamp are measured, and wherein there are the following method steps:depending on the geometry of the pressed part and on the original material during the compression for a pressing stamp a desired force-distance diagram (nominal curve) is determined and stored;in a computer during the compression the measured values for the distance and the force of the pressing stamp are compared to the nominal curve;by way of at least one separately actuated section of the pressing stamp or of a separate stamp the pressure on the pressing material during the compression phase is increased or reduced as soon as a deviation from the nominal curve is determined, in order at the end of the compression pha

  • Patent number: 5640015
    Abstract: A pyrometer for measuring the electromagnetic radiation emitted by an object comprises a first detector to which the radiation is delivered through an optical system as well as a second detector to which the radiation emanating from a reference element is delivered through the same optical system. The temperature of the reference element is monitored and a rotary optical modulator periodically enables and disables the delivery of radiation to the detectors. The output signals from the two detectors are processed to determine the difference therebetween. The sensed temperature of the reference element is taken into account as a part of determining the difference between the two detector output signals. In this way it is possible for the characteristic radiation of the optical system largely to be suppressed. The optical modulator comprises a semi-circular disk having a polyethylene terephthalate substrate coated on each side with metal. The disk is rotated through 180.degree.

  • Patent number: 5223192
    Abstract: A method of monitoring maximum pressing forces of a pelletizing machine provided with a rotatable matrix disc and plungers, involves the steps of supplying values corresponding to pressing forces applied by plungers for evaluation in a computer so as to control a deviating device, detecting a position of the matrix disc continuously by an angle pulse transmitter and releasing pulses by the latter to supply the pulses to the computer, and coordinating the pulses with predetermined maximum pressing force values and supplying to evaluation. The pelletizing machine has a rotatable matrix disc, plungers whose maximum pressing forces are supplied for evaluation, a computer to which the maximum pressing forces of the plungers are supplied for evaluation, and an angle pulse transmitter supplying pulses released by the matrix disc during its rotation into the computer for an association to measured maximum pressing forces.
