Patent number: 9808131Abstract: A of web material for hygiene products includes at least one folded continuous web material, and a first connector and a second connector, adapted for interconnection of the first end surface of the stack to a second end surface of another, similar stack. The first connector includes a first connection surface consisting of a first material, and the second connector includes a second connection surface consisting of a second material; said first and second materials having properties that, upon bringing said first and second surfaces into contact with each other, the surfaces attach to each other by surface adhesion so that the surfaces are repeatedly removable from and reattachable to each other while leaving the surfaces substantially unaltered, whereby a connection between a first/second connector of the stack and a second/first connector of a similar stack is accomplished.Type: GrantFiled: June 10, 2013Date of Patent: November 7, 2017Assignee: SCA Hygiene Products ABInventors: Björn Larsson, Inger Andersson, Gunnel Elglund

Patent number: 8481298Abstract: The present invention relates to a method of preparing a separation matrix comprising at least one insoluble carrier to which sulphate ligands have been attached via extenders, which method comprises coupling, in a first step, of the sulphate ligands to the extenders and, in a subsequent step, attaching the extenders to an insoluble carrier. The invention also relates to a separation matrix comprised of at least one insoluble carrier to which sulphate ligands have been attached via extenders. Advantageously, no sulphate ligands are directly attached to the insoluble carrier. The extenders may be natural polymers, such as dextran, and the insoluble carrier may be made from natural polymers, such as agarose, or synthetic polymers. The invention also relates to a method of purifying virus, such as influenza virus, using a separation matrix according to the invention.Type: GrantFiled: September 26, 2007Date of Patent: July 9, 2013Assignee: GE Healthcare Bio-Sciences ABInventors: Inger Andersson, Andreas Axen, Peder Bergvall, John Clachan, Camilla Estmer-Nilsson, Lena M.

Patent number: 6835379Abstract: A method for producing IgG from plasma for medical applications, comprising at least: (i′) removal of albumin resulting in an IgG fraction, (ii′) purifying IgG from an IgG fraction, which is derived from the IgG fraction obtained in step (i′), by adsorbing IgG to a cation exchanger and collecting the adsorbed IgG fraction, and (iii′) virus inactivation in an IgG fraction derived from the IgG fraction collected in step (ii′). The method is characterized in; (I) concentrating the IgG fraction obtained in step (i′), (II) adjusting pH to 4±0.1 in the IgG fraction released from the cation exchanger in step (ii′), and preferably maintaining the pH below 6.0 during the remaining steps of the method; and (III) carrying out the virus inactivation (step iii′) by using chemicals at a temperature of 30° C.±2° C. for at least 4 hours. Anticomplementary activity is typically below 1 CH50/mg immunoglobulin.Type: GrantFiled: December 9, 2002Date of Patent: December 28, 2004Assignee: Amersham Biosciences ABInventors: Inger Andersson, Lars-Olof Lindquist

Publication number: 20040079500Abstract: An absorbent tissue layer comprises at least one ply where the density of the layer is equal to or less than 130 kg/m3 and the elastic recovery value of the layer is greater than 90%, more preferably 95%, and most preferably 98%. The invention also relates to a product such as a roll or bundle of tissue layer where the elastic recovery value of the layer is greater than 90%, more preferably 95%, and most preferably 98%, and the density of the roll or the bundle is 200 to 300 kg/m3. The ratio between the density of the layer, when it has been separated from the roll or the bundle, and the density of the roll or the bundle is less than 0.65, and the density of the layer when separated from the roll or the bundle is 30 to 130 kg/m3.Type: ApplicationFiled: October 20, 2003Publication date: April 29, 2004Applicant: SCA HYGIENE PRODUCTS ABInventors: Anna Mansson, Magnus Falk, Anders Andersson, Inger Andersson

Patent number: 6026291Abstract: A subscription record within a telecommunication system is sub-divided into three separate registers, namely, a user, a subscription and a terminal register. The use of three separate registers within the system allows several terminals to be associated with one user, several users to be associated with one terminal, several subscriptions to be associated with one user, and several users to be selectively associated with one subscription. The subscription records include a list of allowed users for each subscription account. Additionally, the subscription records include a schedule that defines allowable usage time for each user. The user records include a schedule which defines what subscription accounts will be charged at specified times during the week.Type: GrantFiled: April 9, 1997Date of Patent: February 15, 2000Assignee: Telefonaktiebolaget L M EricssonInventors: Ove Carlsson, Inger Andersson, John Axelsson

Patent number: 4483049Abstract: The invention relates to a theft deterrent device which can be lockably fastened to an article (4) made of cloth, leather, skin or like material, in a manner such that it can only be removed from the article with the aid of special means intended therefor. The device is, to advantage, in the form of a clamp which can be closed around an edge part of the article and therewith automatically locked in position. Arranged in the two halves of the clamp-like device are steel pins which penetrate the material from which the article is made, so that the device sits firmly thereon. The device includes one or more enclosed spaces, preferably in the form of glass ampoules (19) arranged in cavities (15) in the device. The ampoules contain a heavily staining and/or ill-smelling substance, for example a gas or liquid under pressure, and are arranged to break readily if an attempt is made to remove the device by force.Type: GrantFiled: March 30, 1981Date of Patent: November 20, 1984Inventors: Bo O. Gustavsson, Kerstin E. Gustavsson, Inger A. Andersson
