20110238369 | METHOD FOR CHECKING THE DRIFTABILITY OF METALLIC TUBES - The invention relates to a method for testing the driftability of metal tubes, wherein a cylindrical drift body having a defined diameter and a defined length is guided through the tube with defined force for ensuring a predetermined internal diameter and a minimum straightness. Virtual drifting is hereby performed instead of the physical drift operation. | 09-29-2011 |
20110268343 | METHOD FOR THE NONDESTRUCTIVE TESTING OF PIPES - The invention relates to a method for the nondestructive testing of pipes made of ferromagnetic steel for flaws by means of stray flux, wherein the pipe is magnetized by a constant field and the discontinuities present in the near-surface region of the outer or inner surface of the pipe cause magnetic stray fluxes, which exit the pipe surface and are detected by probes of a test unit each for longitudinal and/or transversal flaw testing, wherein the association of the detected amplitude signals is performed on the basis of the amplitude height and/or the frequency spectrum with respect to an external or internal flaw via defined flaw thresholds respectively. To this end, prior to associating the detected amplitude signals to an external or internal flaw, the angular position of the flaw relative to the respective magnetic field direction is determined, and a correction of the signals is carried out via a previously determined correction factor for amplitudes and/or frequencies of a perpendicular angular position. | 11-03-2011 |
20120125111 | METHOD FOR NONDESTRUCTIVE TESTING OF PIPES - The invention relates to a process for the destruction-free testing of metallic pipes, in particular seamlessly produced steel pipes, in which method the entire length of the pipe is scanned following the circumference precisely and in this case, in addition to the wall thickness (WD) and the external diameter (D | 05-24-2012 |
20130131856 | PRODUCTION CONTROL METHOD AND DEVICE FOR CHECKING THE TRAVERSABILITY OF PIPES - A device for checking steel pipes during production and to a method using the device. The device includes a station for acquiring measurement data representative of physical measurements of the geometry of a pipe taken on an outside thereof, and a computer system configured to store template data applicable in a coordinate system and representative of overall geometry of a sizing body. In a chosen coordinate system, the system then provides a three-dimensional representation of parts of the pipe. For each part of the pipe, the system is referenced to determine a critical parameter, representative of the margin of passage of the sizing body inside a chosen part of the pipe. The method and device may thus establish a diagnostic of traversability of the pipe by a sizing body. | 05-23-2013 |

20120047278 | Method, Apparatus and Computer Program Product for Service Decomposition in IP-Broadcast Networks - In a method, an apparatus and a computer program product for service decomposition in IP-broadcast networks, a full service bundle is detected within a first transport stream protocol having a plurality of broadcast packets corresponding to respective broadcast services. The respective service identifiers of the plurality of broadcast packets are evaluated, and the full service bundle is decomposed to create a plurality of decomposed broadcast packets on the basis of the service identifiers. For at least one same service identifier the corresponding plurality of decomposed broadcast packets is sent with the first transport stream protocol as a main service bundle, and for at least one remaining same service identifier the corresponding plurality of decomposed broadcast packets is sent with a second transport stream protocol as a sub service bundle. The second transport stream protocol contains synchronization information of the first transport stream protocol. | 02-23-2012 |

20090178928 | Process for Desalting Glycerol Solutions and Recovery of Chemicals - Processes for desalting glycerol-rich solutions or process streams using electrodialysis are provided. The glycerol-rich process streams are typically byproducts from the production of biodiesel. Following electrodialysis, the resulting aqueous salt solution is placed in a water splitting cell to recover the acid and base components of the salt. These acid and base components, in turn, can be reused in other processes, such as biodiesel production. | 07-16-2009 |

20150360900 | FOLDING MACHINE FOR LARGE-FORMAT DOCUMENTS - A sheet-folding machine has a housing having an off-line intake slot and, offset therefrom, an on-line intake slot, a manual sheet-input table on the housing juxtaposed with the off-line intake slot for feeding of a sheet manually into the off-line intake slot, and an automatic sheet feeder juxtaposed with the on-line intake slot and capable of cooperating with a sheet-processing device to receive a sheet therefrom and feed it into the on-line intake slot. Respective off-line and on-line guide chutes in the housing each have an upstream end at the respective slot and a downstream end. The downstream ends meet at an intersection. A roller-type folding unit in the housing receives a sheet to be folded at the intersection and folds it. | 12-17-2015 |
