  • Publication number: 20230129807
    Abstract: The present invention is an inflatable balloon which is enclosed by an expandable cover which becomes increasingly porous/permeable during expansion. The balloon is coated or enclosed with a matrix which contains a pharmaceutically active agent. During expansion of the balloon, the pharmaceutically active agent is released or extruded through the expandable cover into a body cavity such as an artery or vein. The present invention also provides for a method of treating a disease or condition by delivering the inflatable balloon to a particular body cavity.

  • Patent number: 11179909
    Abstract: A method for removing liquid from a slurry includes: (i) feeding the slurry into the inlet of a press; (ii) removing liquid from the slurry as the slurry advances through a deliquifying section of the press, thereby producing a pressate stream; (iii) forming a plug of material as the slurry is advanced through a plug formation section of the press; (iv) advancing the plug of material to a discharge section of the press; and (v) removing additional liquid from the plug of material by operating the press so that the pressure in the discharge section of the press is greater than the pressure of the pressate stream by at least 2 psi. The present invention also relates to a method for controlling discharge consistency from a press, without provision of discharge restrictors, by varying the pressure differential between a discharge section of the press and a pressate stream.

  • Patent number: 10889795
    Abstract: Discharging pretreated biomass from a pretreatment reactor and mixing the discharged pretreated biomass with a cooling liquid in a vessel provides a cooled slurry having a consistency that is less than about 12 wt %. Since the consistency is relatively low, the cooled slurry may be pumped to a higher elevation using standard pumping equipment. At the higher elevation, the cooled slurry may be separated into a first stream comprising a liquid component of the slurry and a second other stream comprising a solid component of the slurry (e.g., having a consistency between about 15 wt % and 40 about wt %). The solid component may be fed to an inlet of a hydrolysis reactor, while the liquid component may be fed to a cooling system that provides a cooled stream. The cooled stream may then be cycled back to the vessel.

  • Patent number: 10459868
    Abstract: An expansion bridge chip for a modular chip system includes at least one upstream interface for communicating with an application processor module, a plurality of downstream interfaces for communicating with peripheral modules, and an upstream address decoder on each interface for directing data on the upstream interface to a downstream interface. In such an expansion bridge chip, each upstream interface may have a first bandwidth, each downstream interface may have a respective bandwidth, and the expansion bridge chip may be balanced, such that a sum of all respective bandwidths of the plurality of downstream interfaces is equal to the first bandwidth. Alternatively, each upstream interface may have a first bandwidth, each of the downstream interfaces may have a respective bandwidth, and the expansion bridge chip is unbalanced, such that a sum of all respective bandwidths of the plurality of downstream interfaces exceeds the first bandwidth, and interfaces contend for bandwidth.

  • Patent number: 8980599
    Abstract: A process for the production of glucose from a pretreated lignocellulosic feedstock is provided. The method comprises enzymatically hydrolyzing the pretreated lignocellulosic feedstock with cellulase enzymes to produce a hydrolyzate slurry comprising glucose and unhydrolyzed cellulose and fermenting the hydrolyzate slurry in a fermentation reaction to produce a fermentation broth comprising alcohol. A process stream is obtained comprising unhydrolyzed cellulose, which is then subjected to a denaturing step, preferably comprising exposing the unhydrolyzed cellulose to elevated temperatures, thereby producing a heat-treated stream comprising the unhydrolyzed cellulose. The heat-treated stream comprising unhydrolyzed cellulose is then further hydrolyzed with cellulase enzymes to hydrolyze the cellulose to glucose.

  • Patent number: 8328947
    Abstract: A method is provided for hydrolyzing polysaccharides in a lignocellulosic feedstock to produce monosaccharides or pretreating a lignocellulosic feedstock, in which an aqueous slurry of the lignocellulosic feedstock is fed into a pressurized dewatering zone wherein the feedstock is partially dewatered and then is compressed into a plug. The plug is introduced into a reaction zone that operates at a pressure (Pr) equal to greater than about 90 psia and under suitable temperature and pH conditions to hydrolyze the polysaccharides or pretreat the feedstock. The plug provides a pressure seal between the outlet of the dewatering zone and the reaction zone. The pressure (Pdwi) of the aqueous slurry of the lignocellulosic feedstock at the inlet of the dewatering device is related to Pr as follows: 0??P<the lesser of [(Pr?20 psia) and 220 psia], and where ?P is the absolute difference in pressure between Pr and Pdwi in psia.
