  • Patent number: 11838962
    Abstract: Receiving, over a network, a connect request from a first computing device operated by a first user. The connect request comprises a description and/or image of the first user, information indicating the first user made a physical gesture to a second user to signal that a first user requests to connect with the second user, and first user location and time information relating to when the physical gesture was made.

  • Patent number: 8580115
    Abstract: A method of cleaning filtration modules for the treatment of raw water, or wastewater, or activated sludge, is provided by circulating particles in untreated water. The deposits located on the filter membrane outer surfaces are removed by the mechanical action of the particles, without significantly damaging the membrane. Initially, untreated water, wastewater, or activated sludge is chemically-mechanically pretreated. Then the untreated water or wastewater polluted with biologically active material is discharged into a membrane bioreactor system having a filtration unit including at least one filtration tank. At least one submerged filtration membrane module is present in the filtration tank. The untreated water or wastewater in this filtration tank is filled with particles and circulates inside the filtration tank. The particles are non-porous, biologically resistant polymer particles.

  • Patent number: 8013987
    Abstract: A method and apparatus is disclosed for use in fiber optic signature recognition to analyze buried optical fiber to identify a non-threat area along a fiber route and to discontinue monitoring for disturbances along that area of the cable route. The technique includes determining the location of the zone of non-threatening disturbances from comparing an optical signal to the representation of a prearranged optical signal identified as friendly. Once a zone of non-threatening disturbances is identified, all subsequent disturbances in that zone are considered friendly. Cable monitoring is discontinued in the identified zone of non-threatening disturbances so as to avoid monitoring fiber cable when permitted workers are in the area.

  • Patent number: 5256384
    Abstract: To a gas which contains H.sub.2 S and water vapor and which is to be desulfurized oxygen is added at such a rate that the gas contains 1 to 20 moles O.sub.2 per mole of H.sub.2 S. At a temperature in the range of 50.degree. to 180.degree. C. the gas is contacted with activated carbon, which is thus laden with elemental sulfur and with at least 3% by weight sulfuric acid. In a suitable processing, the gas which is to be desulfurized and contains at least 1000 ppm H.sub.2 S+SO.sub.2 is initially passed at a temperature from 100.degree. to 180.degree. C. through a catalytic prepurifier, in which elemental sulfur is adsorbed on a high-metal-oxide catalyst, oxygen is admixed to the gas coming from the prepurifier and the gas at a temperature of 50.degree. to 180.degree. is contacted with the activated carbon for a final desulfurization.
