  • Patent number: 6447875
    Abstract: A die apparatus, a method of using the die apparatus to produce co-extruded polymeric articles, and co-extruded polymeric articles produced using the die apparatus and method are disclosed. The die apparatus includes a hollow vane configured to extrude a material into a chamber within the die, thereby producing a co-extruded web. The co-extruded web has a plurality of distinct, discontinuous phases in the cross-web direction, the phases having a uniform width as shown by a coefficient of variation of less than 8 percent for, any three consecutive phases. The phases are substantially continuous down-web and are surrounded by a matrix having two or more layers.

  • Patent number: 5458938
    Abstract: A mounting laminate can be used as a mounting sheet on which undersize items can be mounted for processing in devices equipped with stacked sheet feed mechanisms. The mounting laminate has three primary layers: (a) a masking layer, preferably paper, formed with discrete openings, preferably circles, (b) a back layer, preferably a thin plastic film, and (c) a pressure-sensitive adhesive layer adhering the masking layer to the back layer and extending across each of the openings.

  • Patent number: 5385230
    Abstract: An adjustable tray assembly adaptable for use in desk drawers having side walls spaced at various distances. The tray assembly includes a first portion having a plurality of open top receptacles and a support lip projecting away from one side, and a second portion also with a projecting support lip and mounted on the first portion to affording relative movement between the portions to change the spacing between the first and second support lips so that they can be supported on the upper edge surfaces of the side walls of the drawers of different widths with the first and second portions bridging therebetween. The tray assembly can also include dispensers for office supplies including note paper, tape flags and tape; the tape dispenser being of a novel low profile design.

  • Patent number: 4907825
    Abstract: A sheet including a layer of flexible polymeric material having a coating of repositionable pressure sensitive adhesive on a second end portion that is generally transparent when adhered to a substrate, while being free of adhesive along a visually distinctive first end portion. A pad of the sheets in a stack with adjacent ends of the sheets aligned and with the first and second ends of successive sheets adjacent can be disposed in a chamber partially defined by a top wall having a slot through which the first end portion of the uppermost sheet projects. Relative movement is afforded between the top wall and the uppermost sheet to afford, as the uppermost sheet is pulled through the slot, alignment of the slot with successive portions of the uppermost sheet toward its second end as those successive portions are peeled from the stack.

  • Patent number: 4393804
    Abstract: Apparatus to apply offset preventing liquid to a fixing roller. A web member is moved from a supply core to a take-up core via a pressure roller positioned to establish a contact nip for the web member with the fixing roller. The web member is supplied with the liquid from an offset preventing liquid applicator positioned to contact the web member between the supply core and the contact nip on the surface of the web member that is brought into contact with the fixing roller.
