Patent number: 4433785Abstract: In the inspection of generally round glass containers where the containers are indexed into the gauging stations or positions by the movement of a starwheel mechanism, the containers are held in a generally upright attitude with their bottoms engaging a pair of spaced rollers extending through a slide plate at the gauging station. Each roller is biased in an upward direction against the container bottom. The containers are rotated, in station, by engagement of the sidewall thereof by a rotating wheel mounted on an axis that is somewhat out-of-vertical to aid in holding the container down against the rollers and slide plate. The gauging rollers each have their vertical movements drive the core of a separate differential transformer. The output of the transformers are amplified, alegebraically summed and fed to a discriminator.Type: GrantFiled: June 24, 1981Date of Patent: February 28, 1984Assignee: Owens-Illinois, Inc.Inventors: Darius O.

Patent number: 4432013Abstract: The present invention relates to an apparatus and method for generating a comparison signal representing the deviation between two analog video signals representing light received from particular inspection points on an object being inspected. The comparison signal is generated with a magnitude representing the ratio between the values of the two video signals. The ratio is calculated with the one of the two video signals having the larger magnitude as the denominator. In order to calculate the ratio, the present invention first converts the two analog video signals to digital form and then determines the log of each of digitized video signal. Next, the negative difference between the two log signals is determined. The negative difference is then exponentiated to determine the ratio.Type: GrantFiled: November 23, 1981Date of Patent: February 14, 1984Assignee: Owens-Illinois, Inc.Inventors: John W. V.

Patent number: 4426898Abstract: A registration control method for a printed label cutoff machine controls both the location of the cut by performing a phase adjustment and the length of the individual labels by performing a base speed adjustment. A strip of labels have eyemarks printed thereon for defining the location at which the individual labels are to be cut. An optical scanner is positioned adjacent the labels and generates a scanner pulse upon detection of an eyemark. A control circuit includes a setup control for automatically running the machine into registration from an initial setup position. The setup control functions to generate a reference pulse a predetermined distance before the scanner is expected to see an eyemark. When the eyemark is detected within a designated window area the control utilizes the scanner pulse and the reference pulse to calculate the phase error for each label and generate a phase correction signal proportional to the actual phase error.Type: GrantFiled: January 10, 1983Date of Patent: January 24, 1984Assignee: Owens-Illinois, Inc.Inventor: Nelson Friberg
