Patent number: 11958009Abstract: A filter device for ambient air filtration has a blower housing with air inlet and air outlet. A device for generating an air flow is arranged in the blower housing and generates an air flow in operation from air inlet to air outlet. A flexible air conducting hose is provided with a first open end connected to the air outlet of the blower housing and with a second closed end. The flexible air conducting hose has openings arranged between first open end and second closed end. Filter elements are arranged in the openings, respectively. The filter elements separate a raw side inside the air conducting hose from a clean side downstream of the filter element. The air conducting hose is inflated in operation of the device by the air flow. The flexible air conducting hose has a reduced air permeability compared to the air permeability of the filter elements.Type: GrantFiled: March 1, 2021Date of Patent: April 16, 2024Assignee: MANN+HUMMEL GmbHInventors: Christoph Schulz, Tobias Warth, Marc Hittinger, Jens Gusek, Maximilian Bauch, Thilo Mueller, Anja Koronai-Bauer, Sylvain Michel Tchale, Roman Eder

Patent number: 11752739Abstract: An extruded multilayer film includes a top layer comprising a blend of a polyolefin and adsorbent silica. The adsorbent silica is 5% or more of the blend and the polyolefin is 95% or less of the blend. The multilayer film is oriented in at least one direction to cause fracturing of the top layer to provide a microporous surface exposing the adsorbent silica gel. The fractured top layer is receptive to receiving a printing ink on an exposed surface thereof with enhanced pigment entrapment and rapid ink drying. A single layer film in the form of the top layer, and also oriented in at least one direction also constitutes a part of this invention.Type: GrantFiled: December 16, 2019Date of Patent: September 12, 2023Assignee: Taghleef Industries Inc.Inventors: Eric Propst, Christoph Michel

Patent number: 6676739Abstract: The invention relates to a method for producing a cellulose solution in an aqueous amine oxide, preferably N-methyl-morpholine-N-oxide, for processing to form cellulosed moulded bodies according to the Lyocell method, whereby said solution has an increased thermal stability. Cellulose is suspended in an aqueous amine oxide and the suspension is converted into the cellulose solution. The inventive method is characterised in that the base use of the cellulose used for producing the solution and of the optionally used additives is detected in a dispersion in aqueous amine oxide solution and in that the cellulose solution is formed by adding a base quantity which matches the detected own consumption of the cellulose and optionally the additives. Cellulose solutions having a stability which is essentially independent from the provenance of the used cellulose can he formed.Type: GrantFiled: October 29, 2002Date of Patent: January 13, 2004Assignee: Thuringishces Institut fur Textil und Kunststoff-Forschung E.V.Inventors: Birgit Kosan, Christoph Michels, Ralf-Uwe Bauer, Michael Mooz, Frank-Gunter Niemz
