  • Patent number: 4560527
    Abstract: A method of making agglomerated cellulosic particles, particularly useful as a cat litter, comprises agglomerating a moist blend of fibers, aggregates of fibers, and/or fiber-sized pieces of a fibrous cellulosic material in a substantially horizontal rotating drum to form agglomerated particles; compacting surfaces of the particles; and drying the particles.
    Type: Grant
    Filed: April 24, 1984
    Date of Patent: December 24, 1985
    Assignee: Kimberly-Clark Corporation
    Inventors: Elwood W. Harke, Robert C. Sokolowski, Russell L. Johnson
  • Patent number: 4345477
    Abstract: An integrated circuit stress transducer system including signal processing circuitry responsive to signals from semiconductor stress sensors where the processing circuitry output signals are compensated for sensor stress sensitivity variations.

  • Patent number: 4212301
    Abstract: A digital tampon of unitary construction made of absorbent material capable of being compressed to self-sustaining form. A portion of the material is compressed to a rod-like shape to provide a rigid central support for the remaining relatively uncompressed portion which originates at the top of the rigid central support and is draped downwardly to surround and extend past the lower terminus of the support to form a finger receiving pocket at the tampon base. During insertion the rigid central rod provides positive support to the softer outer portion, while the portion of the tampon surrounding the finger protects the finger from contact with menstrual fluid. After insertion the finger can easily spread the draped over portion to better deploy and position the tampon within the body.

  • Patent number: 4182334
    Abstract: A perineal shield and discharge containment device comprised of a sheet of flexible material adapted for folding along a plurality of pre-established fold lines to provide a folded configuration which will closely conform to the perineal contours of the human body. The pre-established fold lines radiate outward from a common base point interiorly disposed on the longitudinal center-line of the sheet material. When folded as prescribed, the sheet material has an upwardly concave configuration in both transverse and longitudinal directions with the deepest point of the concavity originating at the base point. When the folded sheet material is positioned in contact with the perineum an upstanding anterior portion, comprising the full width of the sheet, covers the pubic area. From the full width anterior portion the folded sheet tapers back to form a narrow isthmus which fits comfortably between the thighs, then diverges outward to form a full width posterior portion which covers the after-parts of the perineum.

  • Patent number: 4067336
    Abstract: A protective and discharge containment device for the perineum made from flexible sheet material shaped to provide close conformity with changing perineal contours by being folded on a set of pre-established lines radiating outward from a base point interiorly disposed on a line defining the main longitudinal axis of the sheet material. When folded as prescribed, the sheet material takes on an upwardly concave configuration in both the transverse and longitudinal directions with the deepest part of the concavity originating at the base point.
