Publication number: 20210270550Abstract: Lances for a heat exchanger tube lancing machine may be continuously supported in radial direction by being guided in a channel. Each channel has one solid bottom and two solid sides. The top of each channel is covered by a rubberlike lip or lip stripes, for instance a semi-flexible polyurethane sheet. Due to the narrow guiding surfaces within the channel it is possible to use more flexible high-pressure hoses as lances, which will not buckle though there might be severe advancing forces.Type: ApplicationFiled: February 25, 2021Publication date: September 2, 2021Applicant: Acconda LLCInventors: Christian Geppert, Stefan Schroth

Patent number: 10495708Abstract: For the creation of a magnetic resonance (MR) image of a predetermined volume section of an object of investigation, MR data of the volume section are collected along radial trajectories, and each trajectory is assigned a readout direction in which the MR data are collected along the respective trajectory. The MR image is reconstructed on the basis of the collected MR data. In the reconstruction, only MR data are taken into consideration that were collected along trajectories with a readout direction restricted to the field of a solid angle that is defined by a partial surface of a sphere. The partial surface (A) at most corresponds to 75% of the total surface of the sphere.Type: GrantFiled: January 30, 2017Date of Patent: December 3, 2019Assignee: Siemens Healthcare GmbHInventors: Christian Geppert, Robert Grimm

Patent number: 9335395Abstract: In a method for frequency calibration in a magnetic resonance system in a volume section containing an unknown number of determined substances, the predetermined volume section is excited with RF pulses and subsequent echo signals are recorded at different times and spectral information is determined for each of the echo signals, from which a peak value in the spectral information and an associated relaxation time are determined. Dependent on the relaxation time, a substance is determined for each peak value. A frequency adjustment substance dependent of the magnetic resonance system is then implemented. Multiple peak values in the spectral information of the echo signals can be determined.Type: GrantFiled: July 3, 2012Date of Patent: May 10, 2016Assignee: Siemens AktiengesellschaftInventors: Andre De Oliveira, Christian Geppert

Publication number: 20150013725Abstract: A pair of parallel metal lances is driven by a transversal drive into and out of heat exchanger tubes. The lances are supported by a plurality of spaced apart, retractable door supports so that the transversal drive mechanism can approach the tube sheet of the heat exchanger tubes as closely as possible. A pair of rotational drive motors rotates the lances at a user controllable speed. As the lances are moved into the tubes, the interlocked support doors retract one at a time, sequentially. Similarly, as the lances are withdrawn from the tubes, the support doors close one at a time in an interlocked fashion.Type: ApplicationFiled: September 30, 2014Publication date: January 15, 2015Applicant: AQUAJET LTD.Inventors: Christian Geppert, Stefan Scroth

Patent number: 8843192Abstract: A breast coil arrangement for magnetic resonance applications has a placement web that allows an examination subject to lie with her sternum on the placement web with each breast in a receptacle respectively on opposite sides of the placement web. The breast receptacles have limiting elements whose spacing from one another can be adjusted. Multiple array coils are respectively arranged in the limiting elements and are stationary relative to the limiting elements. Each breast receptacle is surrounded by a volume coil that is stationary relative to the placement web. The volume coils are arranged centrally and orthogonally relative to the array coils and surround the array coils. The volume coils are decoupled from the array coils. A spectroscopy phantom can be arranged in proximity to the placement web.Type: GrantFiled: September 14, 2009Date of Patent: September 23, 2014Assignee: Siemens AktiengesellschaftInventors: Christian Geppert, Rainer Kurth, Titus Lanz, Florian Odoj, Silke Quick, Christian Schuster, Alexander Weisser, Tobias Wichmann

Patent number: 8122898Abstract: A rotating and telescoping cleaning system improves high pressure water cleaning of the inner surfaces of vessels or tanks. Vessels can be vertically divided with dividing plates with centered through-holes. Synchronized and controlled transverse and rotary movements of water jets result in a controlled spiral or helical cleaning track along the vessel walls. The water jets are directed at a pre-adjusted distance from the vessel wall and the travel speed of the water nozzle jets is exactly controlled allowing the removal of very hard deposits. One pass with the tool carrier with operating water jets along the length axis of the vessel results in a thoroughly cleaned vessel wall. The tool unfolds and folds inside of the vessel powered by the flow of the high pressure cleaning water.Type: GrantFiled: June 4, 2009Date of Patent: February 28, 2012Assignee: Aquajet Ltd.Inventors: Christian Geppert, Stefan Schroth
