| 20090162911 | STRAIN FOR BUTANOL PRODUCTION - Using screening of transposon random insertion mutants, genes involved in a complex that is a three-component proton motive force-dependent multidrug efflux system were found to be involved in | 06-25-2009 |
| 20090203139 | PRODUCTION OF FOUR CARBON ALCOHOLS USING IMPROVED STRAIN - Using screening of transposon random insertion mutants, genes involved in accumulation of (p)ppGpp were found to be involved in bacterial cell response to butanol. Reduced production of proteins with enzymatic activity for (p)ppGpp biosynthesis confers increased butanol tolerance. Bacterial strains with reduced (p)ppGpp accumulation and having a butanol or 2-butanone biosynthetic pathway are useful for production of butanol or 2-butanone. | 08-13-2009 |
| 20100167364 | YEAST WITH INCREASED BUTANOL TOLERANCE INVOLVING CELL WALL INTEGRITY PATHWAY - Increasing tolerance to butanol in yeast has been accomplished by increasing activity of the cell wall integrity pathway. Yeast with increased expression of SLT2p, a mitogen activated protein kinase of the MAPK module of the cell wall integrity pathway had increased tolerance to isobutanol. These yeast may be used for improved butanol production. | 07-01-2010 |
| 20100167365 | YEAST WITH INCREASED BUTANOL TOLERANCE INVOLVING HIGH OSMOLARITY/GLYCEROL RESPONSE PATHWAY - Increasing tolerance to butanol in yeast has been accomplished by increasing activity of the high osmolarity/glycerol response pathway. Yeast with increased expression of PBS2p, a mitogen activated protein kinase kinase of the MAPK module of the high osmolarity/glycerol response pathway may be used for improved butanol production. | 07-01-2010 |

| 20100225086 | Structure, Components and Method for Constructing and Operating an Automatically self locking manually propelled vehicle such as a wheel chair - Several new and useful concepts for a manually propelled vehicle such as a wheel chair are provided. In one concept, the vehicle is configured to be selectively placed in an automatic lock condition in which (i) the wheel chair can move in a conventional manner while an occupant is seated in the wheel chair, and (ii) the wheel chair is automatically locked against movement when an occupant begins to rise from a seated position on the wheel chair. In another concept, a particularly secure structure is provided for locking the wheel of the wheel chair against movement. In yet another concept, important components of the wheel chair are formed in a manner that facilitates assembly of those components into the wheel chair, by an internal fastening system and in a modular fashion. | 09-09-2010 |

| 20090007835 | Systems and methods for tethering underwater vehicles - Systems for tethering an underwater vehicles using a low strength optical fiber tether. The tether system includes, a mechanical fuse that prevents a high load from acting on and severing the tether that is attached to the underwater vehicle, thus allowing use of far smaller cables than typically used. Upon separation of the fuse, a cable payout system pays out an optical fiber that keeps the underwater vehicle, typically a robotic craft, in communication with the surface vessel. The relatively light weight glass fiber may be reinforced and extended to lengths greater than 40 km allowing deep-sea exploration at depths up to 11,000 m. | 01-08-2009 |
