US Patent:

46442685, Feb 17, 1987

Filed:

Apr 8, 1985

Appl. No.:

6/721101

Inventors:

Jacob H. Malka - Fair Lawn NJ
Joseph P. Hartmann - Ridgewood NJ

Assignee:

Allied-Signal Corporation - Morris Township, Morris County NJ

International Classification:

G01R 2500

US Classification:

324 83R

Abstract:

Apparatus and method for extracting the fundamental component of a complex waveshape (E. sub. T) and for determining the magnitude (V) and phase. theta. of the fundamental component are disclosed. The complex waveshape is converted into digital data relative to a reference signal (E. sub. R) and the in-phase (x. sub. 1) and quadrature (y. sub. 1) components of the fundamental component are determined by a graphical Fourier analysis of the digital data so that the magnitude and phase of the fundmental component relative to the reference signal (E. sub. R) can be determined.

International Classification:

B67D 508
G01G 1952
G01G 2310
G06F 1520

US Classification:

222 56

Abstract:

Disclosed herein is an automatically controlled weigh feeding apparatus including a container for prefilling with a substance, a device for discharging the substance from the container at a controllable rate, apparatus for weighing the substance being discharged and for producing an electrical signal proportional to that weight, a voltage to frequency converter connected to receive the electrical signals, a digital computer, apparatus coupled to an output of the voltage to frequency converter for inputting data signals to the digital computer, the computer being adapted to compute a corrective signal based on the input data signals received, and coupling apparatus coupled between the computer and the device for discharging the substance from the container for controlling the rate of discharge responsive to the corrective signal.

Appl. No.:

5/678391

Inventors:

Ronald J. Ricciardi - Garfield NJ
Angelo Ferrara - Fairfield NJ
Joseph L. Hartmann - West Caldwell NJ

International Classification:

G01G 1104

US Classification:

364479

Abstract:

Disclosed herein is an automatically controlled weigh feeding apparatus including a container prefilled with a substance, a device for discharging the substance from the container at a controllable rate, apparatus for weighing the container and its contents and for producing an electrical signal proportional to that weight, a first amplifier for amplifying the electrical signal, a first analog-digital converter coupled to said first amplifier and a digital computer coupled to said first analog-digital converter for computing the weight of substance remaining in the container. A second amplifier is coupled to said first amplifier and a ramp off-set circuit which is controlled by the digital computer inputs a second signal to the second amplifier means having a controlled stepping output applied as a second input signal to the second amplifier to maintain the output of the second amplifier within a given selected range of amplitude during one time cycle of operation. A second analog-digital converter interposed between the second amplifier and the digital computer. The digital computer is adapted to compute a corrective signal based on the signal received for controlling the discharge of the substance from the container.
