  "abstract": "Exemplary apparatus or method implementations for a universal feeder system configured with a transfer screw feeder within a multi-section clamshell pipe permitting access to the feed screw and pipe interior for inspection, maintenance and/or cleaning during production, without disassembly or screw removal. The clamshell screw feeder pipe provides access to the screw by opening or removing the multi-section top portion of the clamshell pipe. The top pipe section is bolted and or hinges to the bottom portion of the clamshell pipe. The number of segmented multiple clamshell top sections depends on the length of the screw. One or more clamshell top sections may be configured with an inspection port. The universal feeder system configured with a transfer screw feeder within a multi-section clamshell pipe transfers feedstock feed from one or more feed vessels to one or more reactor vessel.",

    "1. Is amended to recite: A universal feeder system for transferring a feedstock feed comprising: a first open-bottom vessel configured to retain and dispense feedstock; a motor operated variable speed live bottom dual screw feeder positioned below and parallel to the open-bottom vessel; said dual screw feeder having a proximal and distal end, wherein said dual screw feeder is operably connected to the open-bottom vessel; a first chute having an open top and bottom; said top juxtaposed to the distal end of the dual screw feeder to receive conveyed material from the feedstock feed; and a first motor operated variable speed transfer screw feeder juxtaposed to and operably coupled with the bottom of the first chute that conveys material; said first transfer screw feeder having a proximal end and a distal end, wherein the first transfer screw feeder is positioned adjacent and perpendicular to the distal end of the live bottom dual screw feeder, wherein the first transfer screw feeder distal end is configured with a flange designed to operably connect the first transfer screw feeder to a second vessel, wherein the first transfer screw feeder is configured within a first feeder pipe comprising a proximal end, a distal end, and a pipe top section configured to detachably attach with a pipe bottom section, wherein the pipe top section comprises a plurality of pipe top section segments configured to open and close providing access to a first transfer screw, wherein the pipe top section segments are hinged to the pipe bottom section, wherein there is a handle on at least one pipe top section segment.",
    "2. The universal feeder system of claim 1, further comprising: a second transfer screw feeder juxtaposed to and operably coupled with the bottom of the first chute that conveys material; said second transfer screw feeder having a proximal end and a distal end, wherein the second transfer screw feeder is positioned adjacent and perpendicular to the proximal end of the live bottom dual screw feeder, wherein the second transfer screw feeder distal end is configured with a flange designed to operably connect the second transfer screw feeder to the second vessel, wherein the second transfer screw feeder is configured within a second feeder pipe comprising a proximal end, a distal end, and a pipe top section configured to detachably attach with a pipe bottom section, wherein the pipe top section comprises a plurality of pipe top section segments configured to open and close providing access to a second transfer screw.",
    "3. The universal feeder system of claim 2, further comprising: a third transfer screw feeder having a proximal end and a distal end, wherein the third transfer screw feeder proximal end is operably connected to the second transfer screw feeder distal end, wherein the third transfer screw feeder is positioned perpendicular to the second transfer screw feeder, and wherein the third transfer screw feeder distal end is configured with a flange designed to operably connect the third transfer screw to the second vessel, wherein the third transfer screw feeder is configured within a third feeder pipe comprising a proximal end, a distal end, and a pipe top section configured to detachably attach with a pipe bottom section, wherein the pipe top section comprises a plurality of pipe top section segments configured to open and close providing access to a third transfer screw.",
    "4. The universal feeder system of claim 1, wherein the feedstock feed comprises material selected from the group comprising sewage sludge, municipal solid waste, wood waste, refuse derived fuels, automotive shredder residue and non-recyclable plastics.",
    "5. The universal feeder system of claim 4, wherein the feedstock feed comprises material selected from the group comprising two or more feedstocks.",
    "6. The universal feeder system of claim 1, wherein the second vessel is a gasifier reactor vessel.",
    "7. The universal feeder system of claim 1, wherein the second vessel is a transfer screw feeder.",
    "8. The universal feeder system of claim 1, wherein the pipe top section further comprises an inlet flange operably connected to the first chute.",
    "9. The universal feeder system of claim 1, wherein the flange designed to operably connect the first transfer screw feeder to the second vessel further comprises a first split flange.",
    "10. The universal feeder system of claim 1, further comprising a second split flange located on the proximal end of the first feeder pipe.",
    "11. The universal feeder system of claim 9, wherein the pipe top section further comprises an outlet operably connected to the first split flange.",
    "12. The universal feeder system of claim 11, wherein the outlet is connected to a gasifier inlet flange using a gasket.",
    "13. The universal feeder system of claim 1, wherein the plurality of pipe top section segments further comprises at least two pipe top section segments.",
    "14. The universal feeder system of claim 1, wherein the plurality of pipe top section segments further comprises more than two pipe top section segments.",
    "15. The universal feeder system of claim 14, wherein the more than two pipe top section segments further comprise a center pipe top section segment configured to be disposed between at least two other pipe top section segments.",

  "description_excerpt": "The present invention relates in general to the field of feedstock disposal including sewage sludge treatment (SST), municipal solid waste (MSW) management, wood waste (WW) processing, refuse derived fuels (RDF) treatment, Automotive Shredder Residue (ASR) and non-recyclable plastics disposal (NRP). Target markets for the present invention include municipalities, landfill operators that clean up and rehabilitate land, waste generators, wastewater treatment facilities, agricultural waste generators, private waste service companies and entrepreneurs invested in renewable energy.\n\nCurrently the combination of a fluidized bed or bubbling bed gasifier include a feeder system for biosolids that are designed for a single specific feedstock. It is a common practice in the industry that these gasification systems have similar feeder devices but require specialized design features to accommodate specific feedstock related to their respective handling requirements. These are often cumbersome, complex and expensive. What's needed is a standardized device and method of feeding diverse feedstock into the reactor chambers of any gasifier.\n\nDefined herein are exemplary apparatus embodiments and methods for a universal feeder system configured with a transfer screw feeder within a multi-section clamshell pipe permitting access to the feed screw and pipe interior for inspection, maintenance and/or cleaning during production, without disassembly or screw removal. The clamshell screw feeder pipe provides access to the screw by opening or removing the multi-section top portion of the clamshell pipe.",
