Inventor: STALTER ROBERT J SR
IPC: B60B7/00
Filed: 1989-12-15
Abstract: An improved composite metal-elastomer styled automotive-type wheel with a three-dimensionally contoured ornamental outboard face formed by a plastic overlay body permanently adhered or affixed to the outboard face, and an improved molding apparatus and method for constructing such a wheel. A plastic overlay body has an annular row of  outboard  pockets  disposed  in  radially  offset,  axially overlapping relation with a annular row of inboard pockets which in turn register with vent openings in the disc to thereby provide air passages through the wheel for brake ventilation.   The outboard pockets preferably are disposed radially remote from the center of the wheel close to the wheel rim, and a relatively thin cross-section of plastic material is molded so as to overlie the outboard rim flange to provide a full-face appearance to the wheel.  In the method and apparatus of the invention the mold cavity is provided with perimeter air vents to enable thin cross-section molding adjacent the outer perimeter of the mold cavity.

Abstract: A carbon black process control system measures input variables such as feedstock flow rate, feedstock quality, air flow rate, air humidity, air temperature, fuel flow rate, fuel quality, and/or potassium additive solution flow rate at spaced intervals while the carbon black reactor is operating. Then, at spaced intervals in time one or more output variables of the carbon black, such as iodine number and/or DBP, are predicted in accordance with a prediction algorithm based on the values of the measured input variables. Then, at spaced intervals in time the predicted values of the output variables, such as iodine number and/or DBP, are averaged. Based on the average values of the predicted output variables, one or more input variables are then adjusted to achieve goal values of the predicted output variables, and thus obtain carbon black of substantially consistent quality. The predicted output variables are also laboratory measured from samples of the carbon black produced at spaced intervals in time while the carbon black reactor is operating. Then, based on both the predicted values and measured values of the output variables, the prediction algorithm is adjusted to improve the accuracy of the prediction of the output variables, and thus produce carbon black of substantially consistent quality.

Title: A method and a device for sensorless control of a reluctance motor
Inventor: HEDLUND BENGT G
IPC: H02P6/18
Filed: 1990-07-20
Abstract: In a method for sensorless control of a reluctance motor the actual magnetic flux is compared with tabulated values of the non-linear function between the magnetic flux and the current for the angular position at which a commutation signal (via P15-P18) is to be emitted to the power stages (1-4) for the stator pole windings (H10-H13) of the motor.   The actual value of the magnetic flux is calculated for each sample interval, based on the sampled values of  voltage  (u via P7)  and  current  (i via P8) according to the relation .DELTA.? = (u-R.i).DELTA.t, where R is the resistance of the actual pole winding and the actual power stage.  The instantaneous flux value .DELTA.? received is added to the value of the magnetic flux previously received.          The added value constitutes the actual value, referred to above, which is to be compared with tabulated values.
