20090000777 | Plate heat exchanger port insert and method for alleviating vibrations in a heat exchanger - An insert is provided in a flow path adjacent to the input and/or output port of a plate heat exchanger to shield heat transfer elements adjacent to the port from high velocity flow. By deflecting and redirecting the high velocity flow from the port, vibration induced stress to the heat transfer elements can be minimized. The insert is provided with a converging nozzle that directs the flow into a narrowed body. The outlet of the insert can be formed as an open end of the body or as a contoured opening in the side wall of the body. Flow can also be more uniformly distributed to the flow channels defined between the heat transfer elements. | 01-01-2009 |

20100266789 | METAL CORD REINFORCED FLEXIBLE PIPE - A flexible pipe for conveying pressurized fluids that has an inner tubular layer, two reinforcing layers, an outer layer and a barrier layer. The reinforcing layers are comprised of metal cords wrapped around the inner tubular layer. The metal cords may be comprised of multiple individual wires twisted about themselves or a central guide line. The barrier layer may be positioned between the two reinforcing layers and penetrate therebetween. Additionally, a method for making a flexible pipe is provided, which includes the use of heat to facilitate the penetration of the barrier layer into each of the reinforcing layers. | 10-21-2010 |

20110321132 | SYSTEM, METHOD, AND POLICY ENGINE FOR GRANTING TEMPORARY ACCESS TO ELECTRONIC CONTENT - A system, method, and Policy Engine for granting a first user temporary access to a second user's electronic content. The Policy Engine receives a request originating from the first user to access the second user's content, and retrieves from a relationship database, relationship information regarding a relationship between the two users. If an access rule matching the relationship information is stored in the Policy Engine, the Policy Engine applies the access rule to control access by the first user for a period of time specified in the rule. If an access rule is not stored, the Policy Engine obtains the access rule from the second user. The Policy Engine allows access when the matching rule grants access and the matching rule has not expired, and denies access when there is no matching rule, when the matching rule does not allow access, or when the matching rule has expired. | 12-29-2011 |

20090220130 | METHOD FOR LOCALIZING LABELS IN A SAMPLE - The invention relates to a method in which labels are introduced in a sample, a flat surface is prepared on the sample and a series of images is made of the sample surface with e.g. a scanning electron microscope. The labels may be gold labels or e.g. fluorescent labels. | 09-03-2009 |
20090302217 | Hybrid Phase Plate - The invention relates to a hybrid phase plate for use in a TEM. The phase plate according to the invention resembles a Boersch phase plate in which a Zernike phase plate is mounted. As a result the phase plate according to the invention resembles a Boersch phase plate for electrons scattered to such an extent that they pass outside the central structure ( | 12-10-2009 |
20100072366 | METHOD FOR CORRECTING DISTORTIONS IN A PARTICLE-OPTICAL APPARATUS - The invention relates to a method for correcting distortions introduced by the projection system ( | 03-25-2010 |
20120128028 | Method of Measuring the Temperature of a Sample Carrier in a Charged Particle-Optical Apparatus - A method of determining the temperature of a sample carrier in a charged particle-optical apparatus, characterized in that the method comprises the observation of the sample carrier with a beam of charged particles, the observation giving information about the temperature of the sample carrier. The invention is based on the insight that a charged particle optical apparatus, such as a TEM, STEM, SEM or FIB, can be used to observe temperature related changes of a sample carrier. The changes may be mechanical changes (e.g. of a bimetal), crystallographic changes (e.g. of a perovskite), and luminescent changes (in intensity or decay time). In a preferred embodiment the sample carrier shows two bimetals, showing metals with different thermal expansion coefficients, bending in opposite directions. The distance between the two bimetals is used as a thermometer. | 05-24-2012 |
20120261586 | Beam Blanker for Interrupting a Beam of Charged Particles - The invention relates to an electrostatic beam blanker for a particle-optical apparatus, in which the blanker is used to generate a train of pulses with a fixed repetition rate. Such pulse trains with a sub-picosecond pulse length are for example used in the study of chemistry in the femtosecond scale. | 10-18-2012 |

20100199266 | Code Execution Visualization Using Software Fingerprinting - A system, method, and computer program for analyzing code execution and software performance characteristics are disclosed. Samples of executing code may be taken based on any of a number of various triggers. For example, samples may be triggered based on function calls, such as malloc calls. Alternatively, samples may be triggered based on occurrence of a specified event. Code execution is graphically displayed such that certain patterns may be easily identified. Multiple redundant function calls and areas of code having excessively deep function calls can be readily spotted. Such areas represent opportunities for performance optimization. | 08-05-2010 |
