Patent number: 9437389Abstract: An assembly of a support plate and an exit window foil for use in an electron beam device. The support plate is designed to reduce wrinkles in said foil, which wrinkles may arise due to surplus foil arising in the assembly process. The foil is being bonded to the support plate along a closed bonding line bounding a substantially circular area in which the support plate is provided with apertures and foil support portions and in which area the foil is adapted to serve as a portion of a wall of a vacuum tight housing of the electron beam device. Another aspect involves a method for using the assembly in a filling machine, as well as a method of reducing wrinkles.Type: GrantFiled: February 1, 2011Date of Patent: September 6, 2016Assignee: TETRA LAVAL HOLDINGS & FINANCE S.A.Inventors: Andreas Åberg, Ulrika Linné, Urs Hostettler

Patent number: 9202661Abstract: An electron beam device having a tubular body of elongate shape with an electron exit window extending in the longitudinal direction of the tubular body. The tubular body is at least partly forming a vacuum chamber, the vacuum chamber comprising therein a cathode comprising a cathode housing having an elongate shape, and at least one electron generating filament and a control grid both extending along the elongate shape of the cathode housing. The control grid and the cathode housing are attached to each other by attachment mechanisms. Free longitudinal end portions of either the control grid or the cathode housing are bent in a direction towards each other to form bulge-like shapes for the formation of electron beam shaping electrodes. The invention is further comprising a method of manufacturing the electron beam device.Type: GrantFiled: June 27, 2012Date of Patent: December 1, 2015Assignee: TETRA LAVAL HOLDINGS & FINANCE S.A.Inventors: Kurt Holm, Toni Waber, Urs Hostettler, Hans Vonäsch

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

Patent number: 6929262Abstract: A sheet diverting assembly comprising at least three sheet access openings (5, 10, 15) through which sheets can be fed; and a rotatable diverting member (2) cooperating with each sheet access opening (5, 10, 15) so as to guide a sheet fed towards the diverting member (2) through one access opening (5, 10, 15) towards one or other of the remaining access openings (5, 10, 15) while rotating in the feed direction. The diverting member (2) includes a plurality of radially extending members (23), the members (23) being sufficiently stiff so as to extend radially outwardly in their rest position but to flex on contact with a sheet as the member (23) rotates.Type: GrantFiled: June 12, 2002Date of Patent: August 16, 2005Assignee: De la Rue International LimitedInventor: Urs Hostettler
