Publication number: 20100307632Abstract: A nozzle for delivering texturized fibrous material into a chamber of a muffler has a body including a texturized fibrous material passageway and a separate directional jet passageway. A method of filling a chamber of a muffler with texturized fibrous material includes the steps of extending a wand into the muffler so that a nozzle on the wand is received in the chamber, discharging a stream of texturized fibrous material into the chamber from a first passageway of the nozzle and discharging a directional jet into the stream of texturized fibrous material from a second passageway of a nozzle whereby the stream of texturized fibrous material is redirected into a desired filling direction to more efficiently fill the chamber.Type: ApplicationFiled: June 3, 2009Publication date: December 9, 2010Inventors: Gunnar B. Nilsson, Lennart Svensson, Stefan Sjunnesson, Bengt-Erik Ingemansson, Luc Brandt

Patent number: 7650771Abstract: A high-pressure press includes a pressure vessel surrounded by a force-absorbing press frame. The high-pressure press also includes a detection structure for detecting changes in length of at least one column comprised in the press frame, the changes in length depending on the pressure inside the pressure vessel. The detection structure includes a limit switch, which is adapted to detect if the change in length of the column has reached a threshold value and, in that case, interrupt a pressing operation in progress and reduce the pressure inside the pressure vessel.Type: GrantFiled: December 21, 2007Date of Patent: January 26, 2010Assignee: Avure Technologies ABInventor: Lennart Svensson
