Patent number: 11839928Abstract: An ultrasonic metal welding device for welding electrical conductors using a compression chamber that is adjustable at least n height and that is delimited on opposite sides by a section of a sonotrode as a first delimiting surface and by at least one section of a counter electrode (156) as a second delimiting surface, wherein for welding, the counter electrode and the sonotrode are displaced relative to one another. The counter electrode used is one that comprises sections (152, 154) of geometrically different working surfaces or is composed of at least two sections that are displaceable relative to one another.Type: GrantFiled: August 31, 2022Date of Patent: December 12, 2023Assignee: SCHUNK SONOSYSTEMS GMBHInventors: Sebastian Rühl, Peter Wagner, Udo Wagenbach, Heiko Strobel

Publication number: 20230332091Abstract: A bioreactor system for receiving a disposable bioreactor bag comprises a receiving container having a container wall which defines a receiving space in which the disposable bioreactor bag is received in an operating state of the bioreactor system. A stirring system projects at least partially into the receiving space and is designed and configured to stir a biomedium present in the disposable bioreactor bag in the operating state of the bioreactor system. At least one baffle, which makes the receiving space smaller and differs from the container wall, serves to reduce a laminar flow of the biomedium. A temperature control medium flows through at least part of the at least one baffle, said temperature control medium controlling the temperature of the baffle.Type: ApplicationFiled: June 17, 2021Publication date: October 19, 2023Applicant: Sartorius Stedim Biotech GmbHInventors: Marco Leupold, Simon Topp-Manske, Ute Husemann, Sebastian Ruhl, Sascha Gärtner, Yannick Stapel, Regina Wollschmidt, Gerhard Greller, Thomas Dreher

Patent number: 8870052Abstract: A method and apparatus for welding lines having metallic braids or strands to form an end node or transit node by introducing a first portion of each line into a compression space of an ultrasonic welding apparatus, wherein the first portions run along a straight line, wherein at least one line has a component at a distance from the end node or transit node to be welded, and at least the line which has the component is attenuated between the compression space and the contact element in a second portion by a change in profile of the line which is imposed using a deflection device. To this end, the line which has the component is oriented in extension of the straight line.Type: GrantFiled: August 17, 2011Date of Patent: October 28, 2014Assignee: Schunk Sonosystems GmbHInventors: Sebastian Ruhl, Heiko Strobel, Sinan Koc, Peter Wagner, Dieter Stroh
