  • Publication number: 20170037485
    Abstract: A method for digesting cellulosic biomass solids in a hydrothermal digestion unit comprises providing a reactor, a gas feed line, a system for feeding biomass into the reactor, a fluid circulation system including a fluid inlet, pump, and injector; providing a digestion medium containing a slurry catalyst in the digestion unit; circulating the digestion medium through the circulation system; supplying an upward flow of hydrogen through the biomass solids; and maintaining the biomass solids and catalyst at a temperature sufficient to cause digestion of cellulosic biomass solids into an alcoholic component; wherein the fluid inlet includes a stinger unit having an upper surface, an inner volume in communication with the catalyst circulation system, and an opening in the upper surface for allowing fluid to enter the inner volume; and allowing digestion medium to flow into the catalyst circulation system via the catalyst stinger.

  • Patent number: 7433716
    Abstract: A communication apparatus is described that automatically allocates the position of participants in a group call at various positions in sound-space. The position of each user is such that the user can distinguish between each participant of the call by the position of their voice. This allows the user to visualise the location of each user, without having to manually determine the position of each user.

  • Patent number: 6984116
    Abstract: Disclosed is a process for reducing the self-adhesiveness of polytrimethylene terephthalate pellets, which can be carried out in a continuous or batch manner comprising the steps of: a) introducing polytrimethylene terephthalate pellets having an intrinsic viscosity of at least about 0.4 dl/g into a conduit containing a liquid which is moving through the conduit, thereby causing the pellets to move through the conduit with the liquid; b) adjusting the temperature of the pellets and the liquid to a temperature of about 50 to about 95° C. for a time sufficient to induce a degree of crystallinity of at least about 35% in the pellets; and c) separating the pellets from the liquid.

  • Patent number: 5656173
    Abstract: A method of removing dispersed oil from an oil in water emulsion is accomplished by the steps of dissolving gas in water to form an aerated solution, introducing the emulsion and aerated solution into a treatment vessel in which is positioned a coalescing media formed by an assembly of closely spaced corrugated plates of oleophilic material, the emulsion and aerated solution passing in contact with the plates to cause oil droplets to coalescence on the plates and small gas bubbles carried with the aerated solution to adhere to the oil droplets to increase the buoyancy of the oil droplets so that the oil droplets more readily rise to the surface of the emulsion, accumulated oil being removed from the surface.

  • Patent number: 4006087
    Abstract: Conduit segments are mounted above a horizontal plate which supports an upper bed of media. The segments have perforations formed on their underside. A screen is draped over each segment and extends down the sides of a cradle mounted on the plate to support the segment. The screen laterally supports the media and functions to isolate the media from a fluid volume beneath the perforations in the underside of the conduit.
