Patent number: 11428568Abstract: Disclosed is a method for determining a remaining empty volume in a container, comprising: measuring a first pressure initially prevailing in the container; feeding in a gaseous pressure-boosting medium through an inlet, into the container; measuring the increased second pressure; determining the pressure increase caused by the infeeding of the pressure-boosting medium; determining a volume of the pressure-boosting medium that has been fed into said container; measuring a temperature prevailing in the container; and determining the remaining empty volume on the basis of the pressure increase, the volume of the pressure-boosting medium, and the temperature. Disclosed also is a method for on-site calibration of a fill-level measuring device in which the volume of the medium in the container is determined on the basis of the method for determining a remaining empty volume, and an on-site calibration module.Type: GrantFiled: August 16, 2019Date of Patent: August 30, 2022Assignee: Endress+Hauser Group Services AGInventors: Jürgen Abraham, Stefan Brändlin, Torsten Thiel

Patent number: 11332854Abstract: A clothing, in particular a drying wire, for a machine for producing a fibrous web, such as a paper or cardboard web, is a planar textile structure from yarns which intersect in a machine direction and in a cross-machine direction. The planar structure has two edges oriented in the machine direction and two edges oriented in the cross-machine direction. The clothing is joinable along the edges oriented in the cross-machine direction in the machine so as to form an endless belt. The clothing is only calendered by introducing energy in peripheral regions which extend along the edges oriented in the machine direction and/or along the edges oriented in the machine cross direction, on account of which in the peripheral regions the MD yarns are welded to the CMD yarns, and the thickness and/or permeability of the clothing are/is reduced.Type: GrantFiled: July 17, 2014Date of Patent: May 17, 2022Assignee: Voith Patent GmbHInventors: Uwe Koeckritz, Juergen Abraham, Wan Zeti Zafina Wan Ahmad Nathri

Patent number: 10501889Abstract: A clothing for a machine producing and/or processing a fibrous web extending in longitudinal and widthwise directions, includes a basic structure providing dimensional stability in longitudinal and/or widthwise directions. The structure includes a band-shaped, one-piece grid having widthwise-adjacent first material strands and polymer material having lengths in a longitudinal direction, and adjacent second interconnected material strands and/or droplets and polymer material, contacting the first strands at contact points forming the grid. The strands and/or droplets are deposited by extrusion of the polymer materials in liquid or pasty state onto a depositing surface forming a portion or all of the grid in liquid or pasty state, the polymer materials are solidified, converting the portion or the grid from liquid or pasty to solidified, stable, self-supporting state producing bonding at the contact points, and removing the portion or the grid from the surface.Type: GrantFiled: May 11, 2015Date of Patent: December 10, 2019Assignee: Voith Patent GmbHInventors: Juergen Abraham, Antony Morton

Patent number: 10435828Abstract: A woven-fabric belt for producing web material, in particular for producing spunbonded fabric, with a plurality of longitudinal threads, running substantially in a longitudinal belt direction, and a plurality of transverse threads, running substantially in a transverse belt direction. The longitudinal threads bind with the transverse threads at binder points, and crown regions of the longitudinal threads are formed on a web-material contacting side. On the web-material contacting side a multiplicity of deposits are provided at least on the longitudinal threads. The deposits do not extend into crown regions and/or deposits which do extend into crown regions in the longitudinal belt direction are asymmetrical in relation to a respective crown region.Type: GrantFiled: July 29, 2015Date of Patent: October 8, 2019Assignee: Voith Patent GmbHInventors: Uwe Koeckritz, Juergen Abraham, Antony Morton

Patent number: 10179976Abstract: An industrial textile for use in a fibrous web forming and/or processing machine has a transversal edge section which can be joined together to render the textile endless. MD-yarns are interwoven with CD-yarns. At least two adjacent MD-yarns form a group, the MD-yarns of each MD-yarn group weaving side-by-side the same weave path with the CD-yarns. Each of the MD-yarn groups has adjacent first and second MD-yarns. The first MD-yarn of a MD-yarn group is non-adjacent the first MD-yarn of an adjacent MD-yarn group and the second MD-yarn of said MD-yarn group is non-adjacent the second MD-yarn of the adjacent MD-yarn group. At each transversal edge section the first MD-yarn of a first MD-yarn group forms a first loop and weaves back into the weave path of the first MD-yarn of a second MD-yarn group. The second MD-yarn group is adjacent the first MD-yarn group.Type: GrantFiled: April 7, 2015Date of Patent: January 15, 2019Assignee: Voith Patent GmbHInventors: Anas Alias, Juergen Abraham

Patent number: 9976254Abstract: A seam for joining together the ends of woven fabric to form an endless belt is particularly suitable for joining the ends of woven synthetic dryer fabrics as used in the dryer section of paper making machines and is particularly applicable to joining the ends of those dryer fabrics in at least the machine direction of the fabric. A papermaking fabric comprising a woven fabric body having opposing ends, said fabric body having a system of MD-yarns interwoven with a system of CD yarns. The MD-yarns include first pairs of MD-yarns, second pairs of MD-yarns and third pairs of MD-yarns and the first and the second pairs of MD-yarns form two seam loops, while the third MD-yarns forms the binder. The loops are at identical length to each other over the whole fabric width. Such seam construction reduces marking and increases the seam strength and seam abrasion resistance.Type: GrantFiled: November 25, 2015Date of Patent: May 22, 2018Assignee: Voith Patent GmbHInventors: Anas Alias, Juergen Abraham

Patent number: 9890501Abstract: A papermaking dryer fabric has a system of MD yarns interwoven with a system of CMD yarns in a single layer weave. The MD yarns have groups each formed of a plurality of adjacent MD yarns weaving in the group side-by-side the same weave path with the CMD yarns. The dryer fabric is flat woven with seaming loops at the widthwise edges of the fabric to make it endless. At least some of the seaming loops are formed by at least some MD yarns of the groups of MD yarns. The MD yarns forming the groups of MD yarns have a circular cross section and the CMD yarns are ungrouped CMD yarns and at least some of said CMD yarns have a non-circular cross section with a width to height ratio of more than 1. The dryer fabric has an air permeability between 25 cfm and 200 cfm.Type: GrantFiled: July 25, 2013Date of Patent: February 13, 2018Assignee: Voith Patent GmbHInventors: Anas Alias, Juergen Abraham
