20090044883 | METHOD OF MAKING A SEAMLESS HOT-FINISHED STEEL PIPE, AND DEVICE FOR CARRYING OUT THE METHOD - In a method of making a seamless hot-finished steel pipe a billet heated to a shaping temperature is pierced by a first shaping to a thick-walled hollow ingot which subsequently undergoes a radial forging process using an internal tool inserted in the hollow ingot and at least two forging jaws of a forging machine. The forging jaws act on the outer surface area of the hollow ingot, wherein the hollow ingot is turned and axially advanced in a clocked manner in the idle stroke phase of the forging jaws. | 02-19-2009 |
20130333433 | METHOD FOR PRODUCING SEAMLESS HOT-ROLLED PIPES IN CONTINUOUS PIPE ROLLING MILLS - In a method for producing seamless pipes, a hot hollow block created previously in a piercing mill is stretched by means of a continuous rolling mill on a mandrel bar to form a parent pipe and the parent pipe is fed directly to a stretch reducing mill or sizing mill as a finishing mill, while forgoing an extracting mill and a reheating furnace, and is rolled there to the required final pipe diameter. The hollow block is pre-dimensioned in its length in such a manner that only a single length is produced as the required parent pipe length during the stretching in the continuous rolling mill and the parent pipe is pulled off of the mandrel rod by the finishing rolling during the subsequent finishing rolling, wherein the rolling is performed using rolling mill components that are designed in the dimensions thereof for handling single lengths. | 12-19-2013 |

20150247937 | ENERGY-SENSITIVE FAST NEUTRON IMAGING DETECTOR AND METHOD FOR ENERGY-SENSITIVE FAST NEUTRON DETECTION - An energy-sensitive imaging detector for fast-neutrons includes energy-selective radiator foil stacks converting neutrons into recoil protons. The foils are separated by gas-filled gaps and formed of two interconnected layers: a hydrogen-rich layer such as a polyethylene layer for neutron-to-proton conversion, and a metal foil layer, such as an aluminum layer, defining a proton energy cut-off and limiting a proton emission angle. Energetic recoil protons emerging from the radiator foil release electrons in surrounding gas in the gaps. An electric field efficiently drifts the electrons through the gaps. An electron detector with position sensitive readout, based on Micro-Pattern Gaseous Detector technologies (such as THick Gaseous Electron Multipliers—THGEM) or other measures provides electron amplification in gas. The charge detector has a dedicated imaging data-acquisition system detecting the drifted electrons thereby sensing the position of the original impinging neutrons. | 09-03-2015 |

20080278184 | Grid Sensor - The invention relates to a grid sensor, including grids of electrode wires, for measuring the electroconductivity of a flow medium in the cross-section of a pipeline. The invention can be especially applied where the flow medium flows at a high pressure and at high temperatures. According to the invention, each electrode wire is mechanically connected to a spring on one side by means of an insulating bead, the spring being arranged in a hole in the sensor body having an axis which is oriented in the tensioning direction of the wire, and fixed to the sensor body in this position. Each electrode wire on the side opposing the spring is covered with an insulating tube arranged in an outwardly guided channel in the sensor body. The insulating tube ends inside the channel, in a cavity filled with a sealing material. Neither the insulating bead nor the insulating tube are located in the cross-section wherein the measurement is to be carried out. | 11-13-2008 |

20120060452 | FILTER AND METHOD FOR GREASE FILTRATION - A filter unit and method for removing grease, oil and other particulates from air, for example, in a kitchen environment. The filter unit includes a housing having an upstream side, an downstream side, and a cavity therebetween, a heat exchanger disposed within the cavity and comprising at least two parallel tubes, at least one entrance aperture disposed on the upstream side of the housing and defined by at least one fin, at least one baffle disposed on the downstream side of the housing so as to be oppositely disposed from the at least one entrance aperture, and at least one exit aperture disposed on the downstream side of the housing adjacent the at least one baffle. The baffle and fin define at least one S-shaped flow path through the housing, and the flow path routes air around a downstream side of a first of the at least two tubes and then around an upstream side of a second of the at least two tubes. | 03-15-2012 |

20100160857 | Hand-Held Electronically Controlled Injection Device For Injecting Liquid Medications - A medication delivery device includes a housing, a door coupled to the housing and moveable between a closed position and an open position. The door permits insertion of a medication container, containing liquid medication, into the housing in the open position. A door opening mechanism is coupled to the door. A push member is axially moveable between a retracted position and a non-retracted position and located external to the medication container. The push member enters the medication container and pushes the liquid medication out of the medication container. A lock mechanism is coupled to the door opening mechanism and prevents opening of the door when the push member is in the non-retracted position inside the medication container, wherein the lock mechanism automatically unlocks the door opening mechanism when the push member is in the retracted position. | 06-24-2010 |

20120060818 | Systems and methods for heat recovery - An embodiment of filter unit heat exchanger according to the present invention provides improved operability and manufacturability. Such device may include a housing substantially surrounding a heat exchange assembly. Provided through the housing are one or more tortuous fluid flow paths used to direct airflow therethrough around portions of the heat exchange assembly for efficient operation. The tortuous path(s) may be provided by one or more nozzle apertures on an input side of the housing and one or more diffuser apertures on an output side of the housing, where the nozzle apertures and diffuser apertures are offset to cause desired airflow deflection. The filter unit may include desired symmetries so as to improve manufacturability and/or installation. | 03-15-2012 |
