| 20090277846 | Water supply thermocline detection and mixing process - A means for mixing drinking water stored in large storage tanks, preventing stratification of the water, detects incipient stratification of water along thermoclines, and, responsive to thermocline detection, generates large mixing bubbles toward the bottom of the tank, causing mixing of layers of water in the tank through turbulence created as the bubbles rise through the tank. | 11-12-2009 |
| 20090279381 | Water tank deicing mixer - A means for mitigating or precluding formation of ice in water stored in large storage tanks generates large mixing bubbles toward the bottom of the tank, causing mixing of thermally stratified layers of water in the tank through turbulence created as the bubbles rise through the tank. Incipient stratification of water along thermoclines is detected and the mixer is engaged only when temperatures of portions of stratified water in the tank approach freezing. | 11-12-2009 |
| 20100176054 | METHOD FOR REMEDIATING SOLIDS IN WASTE LIFTING STATIONS - A process removes or eliminates altogether accumulations of solid and semi-solid, water immiscible materials adhering to walls, and equipment, particularly near the high liquid mark, in tanks of waste liquid lift stations. Compressed gas is used to generate large bubble masses of six inches to several feet in diameter within the waste liquid. As these large bubble masses rise through the liquid in the tank, convection currents generated by the rising bubbles agitate and loosen pieces of accumulations adhering to the tank and lift station equipment, resulting in a slurry of waste liquid and immiscible materials which can then be pumped from the tank by lift station equipment for further processing. In some embodiments, continuous or frequent periodic generation of the large bubble masses prevents the accumulation of such materials altogether. In some embodiments, wastewater aeration is also provided, which, in combination with biological augmentation, further enhances the effectiveness of accumulated material removal. | 07-15-2010 |
| 20100278005 | Magnetic bubble mixer forming plate assembly - An improved bubble forming plate for a mixer employing large bubbles to mix liquids in a tank, comprising a gas injector, a bubble-forming undersurface and at least one permanent magnet affixed to the plate, the magnet providing sufficient magnetic force to retain the plate against the inner surface of the tank. | 11-04-2010 |
| 20110036762 | Digester gas mixer for waste liquid treatment - A mixer for anaerobic decomposition of sludge in a digester, captures and compressed biogas emitted by the decomposing sludge. The compressed biogas proceeds through supply lines to bubble forming plates mounted in the lower portion of the digester, close to or on the digester floor. Biogas accumulates under the forming plates to emerge as large mixing bubbles from 6 inches to 10 feet in diameter along their largest dimension. The mixing bubbles are large enough to move sludge as they rise to the surface and generate a mixing current in the sludge. The mixing current mixes the sludge, and bacteria and other microorganisms to promote the conversion of the pollutants contained in the sludge. | 02-17-2011 |

| 20090313355 | System Method and Apparatus for Portable Digital Identity - Two-way digital media devices typically store digital identifying data that identify the user to providers of content and interactive data. In the case of a Web browser of a personal computer, the digital identity is stored in the form of a plurality of cookies that are used by respective web sites to personalize the web site experience for each particular user. When a user is at a different computer, the digital identifying data is not available. In addition, other types of interactive devices, such as CATV settop boxes, cell phones, PDAs and the like, may not have enough non-volatile memory (persistent storage) to store the digital identifying data. In order to provide users with a portable digital identity, a digital identity server is provided as a server node on the Internet, which retrieves digital identifying data and downloads such digital identifying data to any device upon request. In such manner, the user's digital identity is portable and available at any computer or other digital device that is being used. The system digital identity server permits devices without sufficient non-volatile memory storage to download a digital identity for temporary storage in volatile memory, thereby providing a digital identity in devices without non-volatile memory. | 12-17-2009 |

| 20090138049 | Vertebral Rod Assemblies and Methods - A vertebral rod assembly with first and second members that may rotate about a first axis. Each of the first and second members includes a base and a vertebral support rod extending from the base. An extension extends from the base on the first member into an opening formed in the base of the second member. A ring is sized to extend around the extension. A fastener engages with the ring to lock the first and second members, and to prevent relative rotation between the first member and second member. | 05-28-2009 |
