  • Patent number: 6205831
    Abstract: Cathode cans for use in air depolarized cells, and cells made with such cans. The side wall is stronger than the bottom wall, and has a smoother outwardly-disposed surface than the respective bottom wall surface. Strength, and thus hardness, of the side wall relates to strength, and thus hardness, of the bottom wall, as hardness of 130-185 relates to hardness of 93-117, on the Vickers scale. Preferred hardness of the side wall is about 130 to 185; and of the bottom wall is about 93 to 117. The side wall is drawn, and an outwardly-disposed surface of the side wall is ironed. As ironed, the surface finish is related to surface finish of the bottom wall, at the same stage, as surface finish RA of less than 2, preferably about 0.5 to about 1.5, microinches, is related to surface finish RA of about 2 to about 5, preferably about 2.5 to about 4.5, microinches. Thickness of the side wall is generally up to about 85 percent as great as thickness of the bottom wall.

  • Patent number: 6197138
    Abstract: A machine and process are disclosed for bonding an elastic member to a moving substrate web while the elastic member is in an un-stretched condition. The machine provides for upwardly folding a moving substrate web along a longitudinal centerline while maintaining the side edge regions of the web in a flat un-folded or un-gather condition. An elastic member is applied to the moving web while the elastic member is un-stretched, applying the first and second end regions of the elastic member to the respective first and second side edge regions of the moving web. The end regions of the elastic member are next bonded to the side edges of the web, leaving the remainder of the elastic member un-bonded to the web. The web is then un-folded or un-gathered to its first normal width, stretching the bonded elastic member. At least a portion of the remainder of the elastic member previously un-bonded to the web is then bonded to the web, and the stretched elastic member is allowed to relax.

  • Patent number: 6193701
    Abstract: A personal care article includes a resiliently stretchable outer cover. In a first embodiment, a first zone of the outer cover is embossed forming a pattern of embossments providing a first set of desired properties pertaining to stretch of a portion of the outer cover. A second zone of the outer cover is not modified to provide the first set of properties and thus has different stretch properties than the first zone. In a second embodiment, a first panel is secured to a resiliently extensible second panel. A first zone of the second panel can have a pattern of embossments securing the second panel to the first panel. The embossments cause the first zone to have different stretch properties than a second zone of the second panel that is not embossed thereby to impart the set of stretch properties. In a third embodiment the second panel is pre-stretched to a predetermined degree of elongation before securement to the first panel.

  • Patent number: 6149638
    Abstract: An absorbent article includes an absorbent pad and an extensible outer cover. The absorbent pad comprises an absorbent core surrounded by a first folded layer and optionally a second folded barrier layer. Folds of the first and second folded layers unfold and thereby open when an extensible bodyside liner and/or outer cover of the absorbent article are extended. The folds, when opened, extend the respective folded layers in a respective cross-direction or longitudinal direction. Extension of the folds of the first and second folded layers prevents tearing of the absorbent pad and damage to, or release of superabsorbent material from the absorbent pad during extension of the absorbent article. The folds can comprise T-folds, C-folds, pleated arrangements, corrugations, or the like.

  • Patent number: 6140260
    Abstract: A felt for use in a papermaking machine includes a woven base fabric and a batt layer for supporting the paper web. A flow control layer is interposed between the base fabric and the fibrous batt layer, to impede rewetting of the paper web as the paper web exits a press nip of the papermaking machine. The flow control layer is formed of a porous hydrophobic material. Pressure exerted by the press nip forces water from the paper web through the batt layer and the flow control layer into the base fabric. When the pressure is relieved, the hydrophobic properties of the flow control layer impede back-flow of water to the batt layer and thence to the paper web, thereby impeding rewetting of the web. The flow control layer is preferably formed of a spunbonded filamentary nylon material which is non-circular in cross-section, such as tri-lobed/triangular, and which may be treated with an hydrophobic chemical composition to enhance hydrophobic properties.

  • Patent number: 6129720
    Abstract: An absorbent article includes an absorbent pad and an outer cover. An extensible layer replaces at least one of the tissue layers of the absorbent pad. The extensible layer can be secured to an extensible bodyside liner or an extensible outer cover. The extensible layer is adhesively secured to the inner surface of the outer cover or the bodyside liner. In embodiments where the outer cover is extensible in a cross-direction and/or a longitudinal direction, the extensible layer is extensible in the same directions and moves with the outer cover. Absorbent core is not physically secured to the extensible layer. Thus the extensible layer has free mobility with respect to the absorbent core when the outer cover is extended, without deleterious effect on the absorbent core, or the absorbent pad as a whole. Therefore, tearing of the absorbent pad and damage to, or release, of superabsorbent material from the absorbent pad is prevented.
