    摘要: A device for measuring the water content in small samples of an ink-water mixture. The sample is used as the dielectric for a capacitor cell which includes inner and outer concentric electrodes. The ink sample fills a gap between the electrodes, thereby controlling the total capacitance of the cell. The cell is connected as part of an oscillator circuit, the output frequency of which varies in a known manner with the dielectric constant of the ink mixture, which in turn is determined by the mixture's water content. A display is provided which varies with the frequency of the output signal, thereby indicating the sample's water content. A mechanism is provided for conveniently removing the inner electrode so that a sample can be introduced, and then returning the inner electrode so that the sample floods the gap between the two electrodes. The ends of the electrodes are enclosed by conductive members to contain stray electric field, while thin, removable insulative liners are provided for the opposed electrode surfaces to impede electrolysis and double layer effects, and to facilitate cleaning.

    摘要: A meter is provided which can continuously measure the amount of water in a flowing mixture of water and lithographic ink. The mixture flows between the plates of a capacitor cell. This cell provides capacitance for an audio frequency oscillator. The output frequency of the oscillator is converted to a voltage which is proportional to the output frequency of the oscillator. This voltage is converted to a second voltage which is proportional to the logarithm of the first mentioned voltage and is also proportional to the concentration of water in the mixture. This second voltage is read out in a display device which can be set to read the water content of the mixture of water and ink.

    摘要: A direct-to-press imaging system for use in lithographic printing wherein a master-image printing cylinder is used with separate application of ink and water onto its surface to enable repetitive conveyance of image-formatted ink films onto substrates for printing purposes. The imaging system includes a master-image printing cylinder adapted for receiving a hydrophilic coating layer on its surface and a device for laying down a uniform layer of hydrophilic material on the surface of this cylinder. An apparatus is also provided for applying oleophilic material in image-formatted patterns on top of the layer of hydrophilic material on the master-image printing cylinder to form a printing structure having separate hydrophilic and oleophilic areas of the format to be printed. Further, a mechanism is provided for removing the printing structure including both the hydrophilic and oleophilic materials from the surface of the master-image printing cylinder so that a new printing structure corresponding to a new image to be printed can be formed on the master-image printing cylinder.
