Patent number: 10322499Abstract: A screwing device, which serves for screwing boards (2) onto underlying crossbeams (3) in such a way that the screws are screwed tilted in from the edges (5) of the boards (2). The screwing device includes a base (7) with an oblong foot (8) which in use stands on the upper side of the boards (2), two arms (9) extending tilted out from each their end of the foot (8), and two opposite screw drivers (10), which are mounted on each their arm (9) and each is arranged with means for conveying a disposable belt (34) of releasable screws (6) and for stepwise screwing in screws (6) from the belt (34). With the present invention, the components of a terrace can be screwed faster together than hitherto known, and at the same time the terrace obtains optimal strength.Type: GrantFiled: June 28, 2016Date of Patent: June 18, 2019Inventor: Lars Mikkelsen

Patent number: 9979030Abstract: A strip product consists of a metallic substrate, such as stainless steel, and a coating, which in turn comprises at least one metallic layer and one reactive layer. The coated strip product is produced by providing the different layers, preferably by coating, and thereafter oxidizing the coating to accomplish a conductive surface layer comprising perovskite and/or spinel structure.Type: GrantFiled: July 10, 2014Date of Patent: May 22, 2018Assignee: Sandvik Intellectual Property ABInventors: Mikael Schuisky, Finn Petersen, Niels Christiansen, Joergen Gutzon Larsen, Soeren Linderoth, Lars Mikkelsen

Patent number: 9369507Abstract: The present disclosure describes systems and methods for reliable backup of data, by initially providing transcoded, down-sampled, or low resolution versions of media data files for backup when a network has low bandwidth or intermittent connectivity, and subsequently providing the original or high resolution copy to replace the transcoded version, either on a second, faster or more reliable network, or over time on the first network. Accordingly, even with poor network conditions, data may be backed up quickly in a reduced size in case of damage to or loss of the device, providing a “better low resolution than no resolution” safety margin.Type: GrantFiled: March 12, 2013Date of Patent: June 14, 2016Assignee: Carbonite, Inc.Inventors: David Friend, Lars Mikkelsen, Cory Mintz, James Speth

Patent number: 9269963Abstract: A method for producing and reactivating a solid oxide cell stack structure by providing a catalyst precursor in at least one of the electrode layers by impregnation and subsequent drying after the stack has been assembled and initiated. The method includes impregnating a catalyst precursor into a cathode of a solid oxide cell stack which already contains an active material (an anode reduction) for example, in the form of Ni/YSZ anodes. Due to a significantly improved performance and an unexpected voltage improvement this solid oxide cell stack structure is particularly suitable for use in solid oxide fuel cell (SOFC) and solid oxide electrolysing cell (SOEC) applications.Type: GrantFiled: November 11, 2010Date of Patent: February 23, 2016Assignees: Technical University of Denmark, Haldor Topsoe A/SInventors: Peter Vang Hendriksen, Lars Mikkelsen, Martin Søgaard, Jens Valdemar Thorvald Høgh, Wolff-Ragnar Kiebach, Kresten J.
