Title: Lithographic fountain solution containing mixed colloids
Inventor: GVENTER HENRY W
IPC: B41N3/08
Filed: 1987-06-15
Granted: 1992-02-18
Abstract: ABSTRACT OF THE INVENTION        A lithographic fountain solution concentrate is disclosed, the essential components of which comprises an aqueous mixture of:   a) from about 0.1 to about 1.5 percent by weight of a water soluble film forming hydrophilic gum; b) from about 0.75 to about 8.5 percent by weight of Polyvinyl Pyrrolidone; c) from about 5.0 to about 30.0 percent by weight of a water soluble acid etchant; d) from about 20.0 to about 50.0 percent by weight of a water soluble or water miscible glycol; and e) from about 0.01 to about 1.25 percent by weight of a phosphate/phosphoric acid buffer system.     The concentrate is adapted for further dilution by water to yield a fountain solution which when used in the printing process offers decreased scumming and blinding of printing plates while at the same time permitting a reduction in the amount of water applied to the plate.  Improved print quality, reduced tendency to wet the paper, faster ink drying and improved ink/water balance is thereby achieved.

Abstract: ABSTRACT OF THE DISCLOSURE                An improved transparent touch panel membrane switch for use and shielding in front of a usual display terminal is disclosed. The switch is made up of a plurality of plastic sheets arrayed substantially parallel to one another in a sandwich configuration. The outermost of the sheets has an antireflective hardcoat. Two adjacent but spaced apart inner sheets provide the electrical contacts through transparent low reflectance conductive metal coatings. The switch additionally contains a further inner antireflective transparent electrically conductive coating which provides shielding against the passage of electromagnetic and radio frequency interference through the membrane switch. The layers in this switch all contribute to a relatively low transmittance of back lighting from the visual display terminal but also significantly reduce reflectance such that the overall signal to noise ratio is substantially enhanced.

Abstract: ABSTRACT OF THE DISCLOSURE           An oil reservoir assembly for delivering oil through an oil port in a vertical housing wall of a heavy, clumsy, housed mechanism which must be moved into operating position through a restricted access opening. The oil reservoir assembly is attached to the vertical housing wall in oil delivering disposition relative to the oil port.  During the positioning of the mechanism the reservoir assembly becomes operably associated with the distal end of an oil supply line.  The oil reservoir assembly comprises a casing having a wall with a hole therethrough.  The casing defines an oil reservoir chamber and is adapted for connection to the vertical wall of the mechanism with the oil reservoir chamber in fluid communication with the oil port.  An elongated, frusto-conically shaped guidance member is mounted within the chamber in alignment with the hole.  The guidance member has an internal, longitudinally extending, conically shaped surface and an inlet at one end of the conically shaped surface which is larger than the oil supply line and a relatively smaller outlet at the opposite end of the surface.  The guidance member is mounted with its inlet and outlet disposed in alignment with the hole in the casing.  The hole in the casing and the inlet and outlet of the guidance member are disposed in general alignment with the oil supply line during positioning of the mechanism whereby the conically shaped internal surface of the guidance member is in position to contact the distal end of the oil line during positioning of the mechanism and guide the distal end of the oil line through the outlet and into its correct operating disposition inside the chamber.
