  • Patent number: 6034010
    Abstract: Disclosed is a fabric which includes a microbial adsorbent and which is capable of providing a microbial barrier while still being able to allow passage of water vapor. The fabric is formed from a plurality of fibers which define at least one microporous passageway which allows communication, through the fabric, between its respective first and second surfaces. In particular, a portion of the microporous passageway is defined by the microbial adsorbent so that microbes attempting to pass through the fabric via such a passageway must pass in close proximity to the microbial adsorbent. This arrangement allows the microbial adsorbent to interdict the microbe by adsorbing it. Passage of the microbe through the fabric is thereby prohibited. Laminates of the fabric with other materials are also disclosed.

  • Patent number: 5878381
    Abstract: A system and method for collecting data on individual and aggregate use of toilet tissue or other types of rolled absorbent paper in a public washroom includes a sensing system for sensing one or more characteristics of paper use at a particular dispensing location, and a recording system for receiving and recording data from said sensing system, whereby paper use at the dispensing location can be monitored and studied. The system further analyzes the data to determine such things as the total amount of paper used, the duration of time over which paper is used, the number of discrete pulls on the paper taken by a user and the amount of paper taken by a user per discrete pull.

  • Patent number: 5868153
    Abstract: An ultrasonic apparatus and method for regulating the flow of a pressurized liquid through an orifice by applying ultrasonic energy to a portion of the pressurized liquid. The apparatus includes a die housing which defines a chamber adapted to receive a pressurized liquid and a means for applying ultrasonic energy to a portion of the pressurized liquid. The die housing further includes an inlet adapted to supply the chamber with the pressurized liquid, and an exit orifice defined by the walls of a die tip. The exit orifice is adapted to receive the pressurized liquid from the chamber and pass the liquid out of the die housing. When the means for applying ultrasonic energy is excited, it applies ultrasonic energy to the pressurized liquid without applying ultrasonic energy to the die tip and modifies the flow rate of the pressurized liquid the exit orifice.

  • Patent number: 5855788
    Abstract: A chemically charged-modified filter for removing charged, micron to sub-micron sized particles from an aqueous liquid, the filter being composed of a filter sheet having a plurality of individual exposed surfaces, at least a portion of which having a surface energy of less than about 45 dynes per centimeter; amphiphilic macromolecules adsorbed onto at least some individual exposed surfaces having a surface energy of less than about 45 dynes per centimeter; and chemical charge modifiers incorporated onto at least a portion of the amphiphilic macromolecules; so that when said charge-modified substrate is in contact with the aqueous liquid containing the charged, micron to sub-micron sized particles, said particles are adsorbed onto the chemically charge-modified filter.

  • Patent number: 5822955
    Abstract: A grip for grasping bags includes a member constructed from a suitably pliable material, such as silicon rubber or neoprene. The member has a durometer of hardness from 30 to 50. The grip further includes first and second supports positioned adjacent to the member. The first and second supports have teeth to assist in grasping.

  • Patent number: 5755926
    Abstract: This invention provides an integrated system for recovering fibers from mixed grades of waste paper and simultaneously cleaning (deinking) waste fibers. The system comprises a mild alkaline pulping process with oxygen and hydrogen peroxide followed by rapid decompression of fibers and then by hot washing.

  • Patent number: 5550767
    Abstract: An underflow/overflow detector includes first circuitry that decodes an exponent into an exponent shift value and compares the exponent shift value with a normalize shift value to determine whether an underflow or overflow error will occur. The underflow overflow detector further includes second circuitry that compares the exponent to a maximum and minimum exponent value to determine whether an underflow or overflow error will occur.

  • Patent number: 5548544
    Abstract: An apparatus for rounding an answer produced during the execution of an operation by a multiple stage execution pipeline includes first circuitry for detecting when the operation is iterative and accuracy bits associated with the answer to determine if a rounding calculation is required. When the first circuitry detects a rounding calculation is required, it sets a correction factor for the answer in accordance with a rounding mode and the detected accuracy. In a method practiced by the apparatus, the rounding an answer produced during the execution of an operation occurs through the steps of detecting, when the operation is iterative, accuracy bits associated with the answer to determine if a rounding calculation is required, and, when the rounding calculation is required, setting a correction factor for the answer in accordance with a rounding mode and the detected accuracy bits.

  • Patent number: 5380546
    Abstract: A maskless process for forming a protected metal feature in a planar insulating layer of a substrate is disclosed. A first barrier material is disposed in a recess in an insulating layer, a conductive metal is disposed on the first barrier material such that the entire metal feature is positioned within the recess below the top of the recess, a second barrier material is disposed on the metal feature such that the second barrier material occupies the entire portion of the recess above the metal feature and extends above the top surface of the insulating layer, and the second barrier material is then polished until the top of the second barrier material is in and aligned with the top of the insulating layer. As a result, the metal feature is surrounded and protected by the first and second barrier materials, and the substrate is planarized.
