20100187560 | METHOD FOR BONDING METAL SURFACES, METHOD FOR PRODUCING AN OBJECT HAVING CAVITIES, OBJECT HAVING CAVITIES, STRUCTURE OF A LIGHT EMITTING DIODE - A method for bonding two partially form-fitting surfaces of two metal bodies which contain the same metal is carried out by generating a first layer on the surface of a first one of the two bodies, the first layer containing a mixture of the metal and the oxide of the metal; generating a second layer on the first layer, the second layer containing the metal but less oxide of the metal than does the first layer; placing the partially form-fitting surfaces of the two metal bodies adjacent to each other; heating the bodies placed adjacent to each other to a temperature which lies in a target range below the melting point of the metal and above the eutectic temperature of the eutectic of the metal and the metal oxide; and holding the temperature within the target range over a predetermined or a controllable duration of time. | 07-29-2010 |
20130221396 | OBJECT HAVING INTERNAL CAVITIES, LIGHT EMITTING DIODE ASSEMBLY - An object with an internal cavity may serve as a cooling structure for a semiconductor package. The object includes a stack of form fitting bodies. The stack has a first form fitting body shaped according to the cavity with a first layer forming a partially form fitting surface, the first layer including a mixture of a first metal and an oxide of the first metal, and a second layer adjacent to the first layer. The second layer includes the first metal but less oxide of the first metal than the first layer. The stack has a second form fitting body shaped according to the cavity with a first layer forming a partially form fitting surface configured to conform to the partially form fitting surface of the first form fitting body. | 08-29-2013 |

20130180325 | NOVEL LOW SPEED WIND TUNNEL DESIGN FOR AGRICULTURAL SPRAY PARTICLE ANALYSIS - A wind tunnel device defines a cyclical tunnel to receive continuous airflow. Airflow is delivered through the tunnel to a testing region that includes a first portion carrying an arm including a spray tip configured to spray particulates in the testing region at an angle, and a second portion including an enlarged cutout region configured to receive the angled sprayed particulates. As airflow carries the angled spray particulates into the second portion, the enlarged cutout region enables the spray particulates to pass through and exit the second portion of the testing region. Analysis in the second region may be conducted through transparent walls free of openings to minimize exposure of the spray particulates to the exterior of the device. A scrubber is adapted to extract spray mist from the airflow as the airflow exits the testing region and is re-circulated through the cyclical tunnel. | 07-18-2013 |

20140263730 | DROP NOZZLE - The application is generally directed towards a drop nozzle for an agricultural sprayer. The drop nozzle can be used to reduce spray drift as liquids are deposited by the sprayer. The drop nozzle includes a valve assembly including a shutoff valve, a tube operably connected to the valve assembly, and an airfoil connected to the tube. The shutoff valve selectively prevents fluid flow from the valve assembly to the tube and the airfoil directs airflow around one or more portions of the drop nozzle. | 09-18-2014 |

20080204652 | Hinge for Spectacles - The present invention relates to a hinge for spectacles, the hinge having two spectacle frame parts joined in an articulated manner by an axis element, the end of the first spectacle frame part having a first bend which encloses at least in part the axis element in a pivoting manner, and the second spectacle frame part being secured against rotation to the axis element. Also disclosed is a spectacle frame having this type of hinge. The claimed hinge for spectacles is characterised in that an elastic tongue is formed in the second spectacle frame part, on the side of the hinge, having a second bend which encloses at least in part the first bend of the first spectacle frame part. | 08-28-2008 |

20090309780 | METHOD FOR DISTANCE MEASUREMENT AND DATA TRANSMISSION IN A CONTINUOUS WAVE RADAR SYSTEM - A method for distance measurement and data transmission in a continuous wave radar system is described. A continuous wave radar system has a transmit and receive module and at least one transponder device, a mobile control and monitoring device and an HMI system. Transponder devices are searched for with the aid of an unmodulated continuous wave signal as an interrogation signal, such that the transponder device can send a radio response signal to the transmit and receive module in response to the interrogation signal, as a result of which a data transmission takes place from the transponder device to the transmit and receive module. Upon completion of the data transmission a frequency-modulated continuous wave signal is generated in order to measure, on the basis thereof, a distance between the transponder device and the transmit and receive module. | 12-17-2009 |
