  • Patent number: 6442267
    Abstract: A local routing system is provided for selectively routing traffic in a telecommunications network according to a local service provider's preferences. The local service provider provides service for telephone lines acquired from a local exchange carrier. The telecommunications network supports an originator subscribing to the local service provider. The originator initiates a trigger when originating a call to a destination by dialing a number. The local routing system includes a classifier, a determiner, and a router. The classifier analyzes the dialed number and categorizes the call into one of several predetermined classes of traffic. The determiner determines whether the local service provider has a routing preference for the class of traffic into which the classifier has placed the call.

  • Patent number: 6299781
    Abstract: Water containing difficult-to-remove volatile hydrocarbon contaminants which may include MTBE, TBA and/or BTEX is treated under pressure by electrolysis and oxidative reduction in a contact area, then is depressurized and subjected to high shear in a multi-stage turbine column to precipitate and/or outgas nearly all of the contaminants. In the turbine column, redirect diverters are included below each turbine in order to redirect the water/gas stream to center and to further atomize the stream at each stage. Liquid discharge is received in a bottom reservoir of the casing or tank. Vacuum is applied to the casing, at about 30 inches of water, to constantly remove air and gases from the casing, and causing air to be drawn at high flow rate down through the turbine column, helping volatilize the hydrocarbon components. A submersed pump in the liquid reservoir removes the treated water.

  • Patent number: 6139158
    Abstract: Retroreflective sheeting and articles are formed in which the size of the retroreflective and non-retroreflective surfaces may be varied across an array of microprisms. This is accomplished by varying the location of the reflective coating applied to the microprism side facets, such that, some prism side facets are completely coated with reflective material while others are coated only at the apex area; and still others are coated with a non-reflective coatings, such as, a colored adhesive.

  • Patent number: 5767060
    Abstract: A bonded multi-component filter medium preferably contains at least two active components, namely, activated carbon adsorbent and a blend of at least two organic polymer absorbents. The medium is prepared by adding a selected quantity of carbon of a preselected size to a mixer, then wetting the activated carbon with a water-based aliphatic resin binder adhesive, preferably also with a surfactant, thus eliminating the static charge on the carbon, then adding hydrophobic absorption bonding polymers to the mixer, then thoroughly mixing the hydrophobic absorption bonding polymer with the carbon in preselected proportions, until both the carbon particles and the polymer particles are effectively coated with the binder adhesive. After thoroughly mixing, the medium mixture is preferably poured into filter cartridge forms, and then air-dried at room temperature and low humidity, to cure the aliphatic resin adhesive binder.

  • Patent number: 5657162
    Abstract: Retroreflective sheeting and articles are formed in which the size of the retroreflective and non-retroflective surfaces may be varied across an array of microprisms. This is accomplished by varying the location of the reflective coating applied to the microprism side facets, such that, some prism side facets are completely coated with reflective material while others are coated only at the apex area; and still others are coated with a non-reflective coatings, such as, a colored adhesive.
