20160032072 | BENZIMIDAZOLE BASED AEROGEL MATERIALS - The present invention provides aerogel materials based on imidazoles and polyimidazoles. The polyimidazole based aerogel materials can be thermally stable up to 500° C. or more, and can be carbonized to produce a carbon aerogel having a char yield of 60% or more, specifically 70% or more. The present invention also provides methods of producing polyimidazole based aerogel materials by reacting at least one monomer in a suitable solvent to form a polybenzimidazole gel precursor solution, casting the polybenzimidazole gel precursor solution into a fiber reinforcement phase, allowing the at least one gel precursor in the precursor solution to transition into a gel material, and drying the gel materials to remove at least a portion of the solvent, to obtain an polybenzimidazole-based aerogel material. | 02-04-2016 |

20120241305 | Fast pyrolysis Catalytic Cracking pipe for Producing Bio-Oils - A pyrolyzer apparatus (i.e. a “cracking pipe”) comprises a first screen, a second screen, and a catalyst material positioned between the first and second screens. The pyrolyzer is structured so that feedstock is pyrolyzed and pyrolyzer-generated gas is drawn through the first screen, through the catalyst material, and then through the second screen in series. The gas may then be directed to other processing equipment so that bio-oil is extracted from the gas. | 09-27-2012 |

20120030958 | PEDIATRICIAN'S EXAMINATION TABLE COVER - A roll of paper dimensioned to cover the surface of an associated medical examination table. Successive axial sections of the free end of the roll are elongated axially. Each axial section includes a plurality of indicia representative of units of length disposed on the paper at axially spaced locations on the axial section. The indicia are elongated laterally with respect to the axial section. In some embodiments the respective indicia are differentiated by length or color. The respective indicia may be disposed at axial intervals along substantially the entire axial extent of the entire roll. In some embodiments the respective indicia extend laterally across a substantial part of the lateral extent of the axial section. | 02-09-2012 |
