  • Patent number: 11298934
    Abstract: A print registration system for a beverage can decorator includes an axial registration system and a circumferential registration system. Each registration system is independent and includes a slider that is translated by a motorized lead screw. Axial movement of the axial registration slider is transmitted to axial adjustment of the plate cylinder by a mechanical connection between the axial registration slider and the plate cylinder shaft. Translation of the circumferential registration slider is transmitted to a helical gear mounted to the plate cylinder shaft such that the plate cylinder shaft is rotated by the movement of the circumferential registration slider upon engagement of the helical driven gear with a stationary drive gear.

  • Patent number: 11230093
    Abstract: A device and a method is disclosed to maintain plate and anilox mandrel position stability in print decks of a flexographic printing press. In one aspect, the mandrel bearings associated with at least one of the plate roll and the anilox roll are preloaded for the purpose of eliminating backlash and increasing the positional stiffness of the bearings, and thus the mandrel. In another aspect, the roll drive motor control system is enabled to provide a torque additive command the torque profile to maintain rotational consistency and otherwise overcome torque transients experienced by the motor during print bounce. Accordingly, the problem commonly referred to as print bounce and or print banding is alleviated.

  • Patent number: 11142963
    Abstract: System and methods for optimizing coiled tubing string configurations for drilling a wellbore are provided. A length of a rotatable segment of a coiled tubing string having rotatable and non-rotatable segments is estimated based on the physical properties of the rotatable segment. A friction factor for the rotatable segment is calculated based on the estimated length. An effective axial force for one or more points of interest along the non-rotatable and rotatable string segments is calculated, based in part on the friction factor. Upon determining that the effective axial force for at least one point of interest exceeds a predetermined maximum force threshold, an effective distributive friction factor is estimated for at least a portion of the non-rotatable segment of the string. The rotatable and non-rotatable string segments are redefined for one or more sections of the wellbore along a planned trajectory, based on the effective distributive friction factor.

  • Patent number: 11092573
    Abstract: An inspection apparatus detects one or more characteristics of a material sample and includes a transmitter to transmit an initial signal to the material sample, and a receiver to receive a detected signal from the material sample associated with the initial signal. The detected signal has at least a first harmonic signal component and a second harmonic signal component. Data processing circuitry determines a resonant frequency of the first harmonic signal component and an amplitude of the first harmonic signal component at the resonant frequency, and filters the detected signal using a first filter signal having a frequency corresponding to the first harmonic signal component and a second filter signal having a frequency corresponding to the second harmonic signal component. A frequency analysis is performed in the frequency domain on the filtered first and second signals to determine corresponding first and second amplitudes. The first and second amplitudes may be compensated for nonlinearity.
