20100230584 | Method for setting an operating parameter of a particle beam device and a sample holder for performing the method - A method for adjusting an operating parameter of a particle beam device and a sample holder, which is suitable in particular for performing the method are provided. An adjustment of an operating parameter of a particle beam device is possible without transfer of the sample holder out of the particle beam device. A reference sample is placed in a first sample receptacle, so that in ongoing operation of the particle beam device, the sample holder need only be positioned in such a way that the reference sample is bombarded and measured with the aid of a particle beam generated in the particle beam device. | 09-16-2010 |

20150214004 | METHOD FOR PREPARING AND ANALYZING AN OBJECT AS WELL AS PARTICLE BEAM DEVICE FOR PERFORMING THE METHOD - A system and method are provided for preparing and analyzing an object having a region of interest. Material is removed from a first surface of the object using a second particle beam. The first surface is monitored using a first particle beam and a second detector. A second surface of the object is generated when the material is removed from the first surface. Material is removed from the second surface using the second particle beam, and the removal of the material is monitored using the first particle beam and the second detector. Removing the material generates a first side and a second side, and the region of interest is arranged between the first side and the second side. The first particle beam is guided to the first side, and first charged particles of the first particle beam being transmitted through the region of interest are detected using a first detector. | 07-30-2015 |

20110003331 | Method for enhanced production of biofuels and other chemicals using biological organisms - The invention of this disclosure, also known as the method of this disclosure, provides the means of improved Chemical Product production from chemical production systems that use biological organisms to produce the desired chemicals. This improved production is by means of subjecting chemical producing organisms to vibration waves or to an electrical voltage potential. The waves or voltage accomplish one of two things or both: they will improve the extraction of the chemicals from the bodies and cells of organisms, or they will increase the rate at which the organisms synthesize chemicals. To illustrate how one of many possible chemical production systems can incorporate this method, a specific configuration for a continuous chemical production system called the Oil Production System | 01-06-2011 |
20110005193 | Method and apparatus for simplified thrust chamber configurations - The invention of this disclosure is methods and apparatuses improving the ease of fabrication and delivered specific impulse performance of simplified rocket engine thrust chambers. Included are a method and apparatus for a pool-boiling cooling system rocket thrust chamber. This cooling system utilizes a convective coolant flowing in a continuous or semi-continuous coolant loop. In addition the convective coolant itself is cooled in a pool-boiling heat exchanger by the evaporation of a propellant that functions as a boiling coolant. The invention also includes a method and apparatus for a shortened, simplified, conical expansion nozzle for a rocket thrust chamber that can operate with reduced specific impulse losses due to nozzle configuration and the use of film coolant in the thrust chamber. | 01-13-2011 |
20120060464 | SYSTEMS, METHODS AND APPARATUS FOR PROPULSION - In some implementations a propulsion system includes a thrust chamber comprised of a combustion chamber and an expansion nozzle. The thrust chamber has an interior and exterior surfaces and a main propellant injector mounted to the thrust chamber to inject an oxidizer and a fuel into the interior of the thrust chamber. The total fluid flowing to the rocket engine is compromised of oxidizer, fuel, internal film coolant, and external convective coolant. The internal film coolant ranges from about 1% to about 10% of the total fluid. Reduced coolant tubing circumscribes the exterior of the thrust chamber to circulate an external convective coolant, and a nozzle film coolant manifold mounted to the expansion nozzle injects the external convective coolant onto the interior wall of the expansion nozzle, the external convective coolant being about 1% to about 10% of the total fluid flow to the thrust chamber. | 03-15-2012 |
