  • Patent number: 6752013
    Abstract: A web tension measurement device includes a roller for a web of material, the movable roller having an axis of rotation moveable in a first direction by the web; a counteracting device connected to the movable roller, the counteracting device for forcing the axis of the roller in a second direction opposite the first direction; and a controller connected to the counteracting device for measuring the web tension. Also included is a method for measuring tension in a web which comprises the steps of running a web over a roller, an axis of the roller being movable in a first direction, counteracting the movement of the roller in a second direction opposite the first direction, and measuring a counteracting force or a variable so as to be able to determine a web tension.

  • Patent number: 6684776
    Abstract: A method for determining the presence of slipping of a driven nip roller relative to the web in a web printing press includes systematically changing the speed of the nip driver while monitoring the corresponding change in web tension difference across the nip. The linearity and a slope of the relationship between the tension difference and the speed of the nip driver are determined. When the tension difference is non-linear relative to the speed of the driver or the slope of the relationship is substantially less than an expected slope, then slipping is determined to be present. An operator slip indication may be provided which includes the direction of the slip, positive or negative. The operator may then take corrective action to re-establish a non-slip condition, or automatic corrective actions may ensue.

  • Patent number: 6499639
    Abstract: A method for dynamically controlling a driver of a nip roller in a web printing press includes controlling the speed of the driver in a tension-control mode during a phase of printing press operation and in a velocity-control mode during another phase of printing press operation. The controlling of the speed of the driver in the tension-control mode is based on the tension in the web upstream of the nip roller so as to maintain the tension at a desired tension value. The controlling of the speed of the driver in the velocity-control mode is based on a predetermined driver velocity ratio for maintaining the web tension. The tension-control mode may be employed during press start-up as the web accelerates to operating speed. The velocity-control mode may be used during printing operations of the press.

  • Patent number: 6433499
    Abstract: An apparatus for calibrating a tension transducer for a web includes a pair of nip rollers and a motor for driving at least one of the pair of nip rollers, the motor having at least one roller output being a function of at least one of a motor torque and a motor velocity. A web tension transducer roll is located upstream of the nip rollers, the web tension transducer having a tension output being a function of the actual web tension of the web. A processor receives the at least one roller output and the tension output, the processor calculating a tension correction value as a function of the at least one roller output and the tension output.

A separable metal retainer is provided for fixing the plastic ring within the housing bore and around the shaft with the separable metal retainer having a surface of revolution with a rear portion having a radius suitable for press fitting into the housing bore and a front portion of lesser diameter ending therein. An internal groove is provided into the plastic ring body for engaging the ring therein in order to latch the plastic ring and the metal retainer together with residual stress in both the axial and radial directions within the plastic ring due to groove and ring dimensions and shape.

  • Patent number: 5999881
    Abstract: This present invention makes use of a method for automatically finds collision-free part removal paths. The system sparsely samples the high-dimensional state space and maps the rest of the space using proximity assumptions (assumptions about states near the samples). The present invention is less complex and faster than previously known methods.

  • Patent number: 5908394
    Abstract: To determine a cataract or the degree of cataractogenesis in an eye of a patient, the patient views two lights juxtaposed, wherein each light comprises a mixture of two different wavelength lights. One of the lights is a fixed reference mixture, while the mixture of the other non-fixed light is varied until the patient observes less distinction between the two light mixtures in terms of brightness, hue or saturation. The luminance levels of the light components of both light mixtures for providing comparison and the ratio levels of the components are predetermined. Once a transition range is established from the comparison, the predetermined ratios are then related to respective ratios of a standardized group. Deviations between the ratios of the patient and the standardized group indicate the existence of a cataract and/or the degree of a cataract precursor formation.

  • Patent number: 5766639
    Abstract: The invention provides a composition and method for reducing molecular defects in metastable tissue systems. Molecular defects represent spaces or vacancies in the structural order of the metastable system. The effect of molecular defects can be minimized such that the pre-defect order is preserved through the use of structure makers. These structure makers will then occupy the space or vacancy of the molecular defect, preserving the pre-defect order of the system. Lithium ions are a preferred structure maker.

  • Patent number: 5609159
    Abstract: To determine a cataract or the degree of cataractogenesis in an eye of a patient, the patient views two lights juxtaposed, wherein each light comprises a mixture of two different wavelength lights. One of the lights is a fixed reference mixture, while the mixture of the other non-fixed light is varied until the patient observes a match between the two light mixtures in terms of hue, brightness and saturation. The luminance levels of the light components of the non-fixed mixture for providing the match and the proportionate levels of the two components are then determined. The shorter wavelength light of the non-fixed mixture is then substituted with a new wavelength light and the new mixture varied again until the patient observes a match as before. Alternatively, a polarization state of the shorter wavelength light is altered before determining a new mixture for obtaining a match.

  • Patent number: 5516534
    Abstract: The invention provides a composition and method for reducing structural defects in metastable systems. Structural defects represent spaces or vacancies in the structural order of the metastable system, which can be restored to the predefect order through the use of structure makers. These structure makers will then occupy the space or vacancy of the defect, restoring the order of the system. Lithium ions are used as a preferred structure maker to reduce the structural defects that lead to cataract in a human lens.
