Patent number: 8907554Abstract: An assembly of a support plate and an exit window foil for use in an electron beam generating device. The support plate is designed to reduce wrinkles in the foil. The foil is bonded to the support plate along a closed bonding line bounding an area in which the support plate is provided with a pattern of apertures and foil support portions alternately. When vacuum is created in the housing the pattern is adapted to form a topographical profile of the foil substantially absorbing any surplus foil. Another aspect involves a method in a filling machine for sterilizing a packaging material web.Type: GrantFiled: February 1, 2011Date of Patent: December 9, 2014Assignee: Tetra Laval Holdings & Finance S.A.Inventors: Ulrika Linné, Werner Haag, Toni Waber, Mattias Henriksson, Kurt Holm, Krister Kristiansson

Publication number: 20140126702Abstract: An X-ray emitter is suitable for evenly sterilizing large volumes of material in a short time, the emitter having an elongated X-ray target window and correspondingly elongated electron source mounted in a vacuum chamber. The electrons from the electron source are accelerated towards the X-ray target window, which generates X-rays directed outward from the vacuum chamber when irradiated by electrons from within the vacuum chamber. The elongated form of the electron source ensures that an evenly distributed beam of electrons, with a substantially constant linear distribution over the length of the electron source, arrives at the elongated X-ray target window such that a correspondingly even distribution of X-rays is generated from the X-ray target window. The X-ray target window includes a support substrate, and carries an X-ray target layer made of a target material such as tantalum or tungsten on its inner surface. A process for manufacturing the X-ray emitter is also described.Type: ApplicationFiled: June 8, 2011Publication date: May 8, 2014Applicant: COMET HOLDING AGInventors: Werner Haag, Toni Waber, Hans-Rudolf Elsener, Benno Zigerlig, Dominique Cloetta, Urs Hostettler
