Abstract: A method and apparatus for validating the flow calibration factor of a Coriolis flowmeter. In accordance with a first embodiment, an improved material density is obtained by measuring material density when the temperature of the material is equal to a predetermined reference temperature. In accordance with a second embodiment, a preprogrammed data base stores density/temperature relationships. Improved density information is obtained by measuring the density and temperature of the material, applying the measured density/temperature information from the data base, and obtaining density information compensated for a predetermined reference temperature. The improved density information obtained for both embodiments is unaffected by temperature changes and is used to validate the flow calibration factor. The flow calibration factor compensation for pressure changes and changes in material composition is obtained in a similar manner.

Abstract: A continuous inkjet device emits a stream of fluid from nozzles. Droplet break-off is stimulated by the application of external perturbing stimulus to the stream in a manner that controls the formation of satellite drops. Satellite behavior is controlled by the use of a composite perturbing signal, composed of at least two frequencies that are not harmonically related, but are related by the ratio of small integers. In one embodiment, the use of two perturbing signals with frequencies fL and fH having a ratio of M/N, where M and N are integers, and M is not a multiple of N, and N is not a multiple of M, produces a repeating drop pattern of either M or N drops at the beat frequency of the combined signal, the constituent drops in said repeating pattern have different satellite formation characteristics.

Abstract: Methods and apparatus for determining the optimal adjustment of imaging systems used to prepare lithographic printing surfaces for a printing press are described. A series of test patterns are imaged while varying a particular imaging parameter. This is followed, if necessary, by processing the plate in processing line. The plate is then returned to the digital imaging system where the reflectivity of the imaged test patterns is measured using a radiation source and detector, to determine the optimal setting for the parameter.
