RADIATION SOURCE AND A METHOD FOR GENERATING ELECTROMAGNETIC RADIATION AT A PLURALITY OF FREQUENCIES
Publication number: 20240128708Abstract: A radiation source includes an initial source, a non-linear optical frequency converter, a conversion detector and a controller. The controller is arranged such that in a first mode of operation, the controller generates the conversion control signal in dependence on the conversion measurement signal such that the resonance frequency is controlled to follow the initial centre frequency. The controller is selectably switchable between the first mode of operation and a second mode of operation. In the second operating mode the power of the converted radiation is controlled such that either the power of the converted radiation has a smaller relative variation over time than the power of the initial radiation in the beam direction in front of the coupling mirror or the power of the initial radiation in the beam direction behind the coupling mirror has a smaller relative variation over time than the power of the initial radiation in the beam direction in front of the coupling mirror.Type: ApplicationFiled: October 12, 2023Publication date: April 18, 2024Applicants: HÜBNER GmbH & Co. KG, Fraunhofer-Gesellschaft zur Förderung der angewandten Forschung e.V.Inventors: Jens KIESSLING, Maik-Hendrik SCHUBERT, Marius Horst Jürgen WENDEROTH, Korbinian HENS -
Patent number: 11745237Abstract: A cooling group for a laminar cooling device, including at least one cooling unit arranged above and below a strip to be cooled in order to supply the strip with a cooling liquid, including a central inlet via which cooling liquid is supplied, a distributing tube supplied with cooling liquid by the central inlet, and a number of supplying units supplied with cooling liquid from the distributing tube. Each supplying unit has a number of cooling nozzles via which cooling liquid is discharged onto the strip. In order to minimize the influence of the number of supplying units which are switched on or switched off, and thus have as little expenditure as possible, a volumetric flow rate regulating valve is arranged in or in front of the central inlet. The regulating valve is used to conduct a defined volume of cooling liquid through the central inlet per unit of time.Type: GrantFiled: February 7, 2019Date of Patent: September 5, 2023Assignee: SMS GROUP GMBHInventors: Johannes Alken, Henning Berg, Jens Kiessling-Romanus, August Sprock

Publication number: 20150328670Abstract: The present invention relates to a method of dynamically supplying coolant to a cooling device, in particular at least one spray bar, for cooling metal strip or other rolled stock. According to the method, a pre-accelerated stream of coolant is provided, which passes by the cooling device (1) and is fed into a return (3). Furthermore, the presence and/or the temperature of a metal strip or other rolled stock to be cooled is monitored and, dependent on the presence and/or the temperature of the metal strip or the other rolled stock, the stream of coolant is diverted to the cooling device (1), wherein, instead of passing by the cooling device (1) and being fed into a return (3), the stream of coolant is fed to the cooling device (1) for cooling the metal strip or the other rolled stock. The present invention also comprises a corresponding device for carrying out the method.Type: ApplicationFiled: July 5, 2013Publication date: November 19, 2015Inventors: Johannes Alken, Uwe Baumgaertel, Ulrich Cramer, Wolfgang Fuchs, Rudolf-Franz Jaeger, Jens Kiessling-Romanus, Matthias Krueger, Frank Theobald

Patent number: 8755692Abstract: A method for wireless data transmission between a transmitter and a receiver includes modulating signals onto an electromagnetic carrier wave in a frequency range between 0.1 and 10 terahertz, and transmitting the carrier wave by the transmitter and focusing the transmitted carrier wave in the direction of the receiver. The transmitter is aimed towards the receiver by an adjusting system using a wireless communication link between the transmitter and the receiver so as to provide automatic aiming.Type: GrantFiled: April 8, 2009Date of Patent: June 17, 2014Assignee: Deutsche Telekom AGInventors: Ralph Michaels, Hans Joachim Einsiedler, Thomas Moersdorf, Gerhard Kadel, Josef Kraus, Klaus Milczewsky, Michael Kern, Karsten Buse, Ingo Breunig, Rosita Sowade, Jens Kiessling, Bastian Knabe
