  • Patent number: 4226886
    Abstract: The present invention relates to a pad capable of high liquid retention and capable of self-metering of liquid from the pad upon application of pressure. Such pads are highly desirable in lubricating applications and serve well as printers and ink reservoir for computers, markers and printing machines. The process comprises mixing a void former, typically a non-reactive salt of a size range chosen between 2 and 450 microns with a polymeric material in a weight ratio of 2.5:1 to 10:1 salt to polymer. The polymer is heated and the salt dispersed therein to form a salt-polymer composite. The composite is fed to an extruder and extruded to a desired shape, a dense skin being formed on the surface of the extruded polymer. Subsequently, the extruded polymer is cut, the salt is leached from the polymeric matric with a suitable solvent, and the leached extruded polymeric matrix is dried. The skin layer has narrower channels and a lower void volume than the adjacent reservoir column.

  • Patent number: 4052938
    Abstract: There is disclosed printing apparatus having a pivotally mounted print head which cooperates with a platen, a cam shaft to which a cam is secured for actuating the print head and to which another cam is secured for driving an operating lever. The cam means is part of a lost-motion connection which couples the slide to the inker. As the operating lever is cammed in one direction to move the feed finger forward, the inker is moved into and out of inking cooperation with the print head assembly. Both an ink cartridge and an ink pad assembly are mounted on yieldable supports to promote uniform pressure contact and hence uniform inking. The print head is provided with toothed drive wheels and one or more intervening blank elements or spacers each having tooth surfaces defining a gap or space which enables an indexing gear to be shifted smoothly relative to the toothed drive wheels.

  • Patent number: 4011813
    Abstract: A hand-held label dispensing and applying apparatus includes a label applying roller adjacent dispensing edge member which serves to detach individual labels from a strip of labels having spaced notches along its length. Labels are advanced from a store to the dispensing edge member by a movable member carrying barbs which engage the strip notches to carry the strips back to a second series of barbs and to print the label on the movable member by a print-head assembly. The movable member effectively forms a printing platen. When the movable member returns to its rest position, the second series of barbs draw a fresh label over the dispense member since they have become engaged with a fresh length of the strip.
