20120138319 | FIRE EXTINGUISHING BOMB - A fire-extinguishing bomb that can be pre-programmed to explode 2-200 feet above the ground or tree line. The bomb employs a laser or barometric altitude sensor in combination with a GPS-altitude sensor for failsafe detonation with extreme accuracy at the proper altitude. The redundant failsafe altitude-dependent detonation system ruptures a container carrying a payload of wet or dry fire retardant/suppressant, preferably dry environmentally-friendly fire-retardant powder having no toxicity and having fertilizer properties. Upon detonation the device coats the ground below with a uniform fire extinguishing coating. The core components of the bomb can be biodegradable, or alternatively can be readily retrieved and reused after each activation, thereby increasing both economy and reducing environmental concerns. | 06-07-2012 |

20110021749 | Chemical Plugs used with Automated Organic Polymer Synthesizers - A method and system for organic polymer synthesis utilizing flow through reaction vessels. A chemical plug is introduced selectively into reaction vessels that are inactive. Reactions continue in other reaction vessels. The chemical plug may be removed after reactions in the other reaction vessels have been completed. All reaction vessels are under a pressure differential which, with the use of the chemical plug, remains uniform. | 01-27-2011 |
20130323138 | SYSTEM FOR PERFORMING AUTOMATED SOLID PHASE EXTRACTIONS - The invention provides an improved instrument for automation of solid phase extraction chemistries typically used in biotechnology labs. The instrument includes a mechanism for transferring samples dissolved in a liquid from initial containers to reaction columns that are used to perform solid phase extractions. Samples, reaction columns and collection containers are in microtiter plate format or tubes that are on 18 millimeter centers. The transfer system is automatically cleaned after use in preparation for the next use. A dispense manifold is used to dispense various reagents into the reaction columns. Pressure differential is used to move reagents through reaction columns. A sliding cover is used to divert the reagent exiting reaction columns to waste or allowing collection of sample as it exits outlets of reaction columns. Samples are automatically collected in microtiter plates or in individual tubes or vials. | 12-05-2013 |
20140377134 | SYSTEM FOR CONTROLLING AND OPTIMIZING REACTIONS IN SOLID PHASE SYNTHESIS OF SMALL MOLECULES - A instrument for performing synthesis of small molecules such as Oligos and Peptides when using solid phase synthesis techniques to synthesize small molecules. The system and methods include a mechanism for controlling the pressure differential across the reaction vessels that contain the solid support used in solid phase synthesis. Reaction vessels are held in a holder that provides a sealable chamber at the outlet ends of the reaction vessels. The rotor containing the reaction vessels is placed within a sealable chamber. The sealable chamber is fitted with a means for engaging the rotor and draining the reaction vessels to waste. The sealable chamber is also fitted with a means for engaging the rotor to drain the reaction vessels at a slower, variable rate. | 12-25-2014 |
