  • Patent number: 9808131
    Abstract: 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.

  • Patent number: 9668621
    Abstract: A stack of folded web material for hygiene products, such as paper or nonwoven products, said stack including: at least two webs, the webs including: a first web divided into individual sheets by means of lines of weakness; and a second web divided into individual sheets by means of lines of weakness; said first and second webs being interfolded with one another so as to form said stack; and wherein the first web and the second web are arranged in said stack such that the lines of weakness of the first web and the lines of weakness of the second web are offset with respect to one another along the webs; each line of weakness having a separation strength, being the force required to separate an individual sheet from the web along said line of weakness.

  • Patent number: 9572461
    Abstract: A dispenser for a roll of web material, such as a center feed roll includes: a body having a first end wall provided with a dispensing opening for dispensing a leading end of the web material at the center of the roll, a second end wall opposite to the first end wall, and a sidewall connecting to the first and second end wall. The dispenser also includes a stabilizing device that is insertable into the roll to prevent the roll from collapsing towards its center. The stabilizing device includes a plurality of protrusions protruding from at least one of the first or second end wall towards the other of the first or second end wall, and the protrusions are disposed closer to the sidewall than to a center axis of the body.

  • Patent number: 8481298
    Abstract: 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.

  • Patent number: 7487873
    Abstract: A packing for a stack of tissue paper or nonwoven, where the top and/or bottom layer is provided on its outside with at least one glue layer, which packing comprises a packing wrapper. The packing wrapper has, at least within the area of each glue layer, a small capacity to adhere to the glue layer(s) of the stack on at least the side which faces the stack.

  • Patent number: 6835379
    Abstract: 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.

  • Publication number: 20040079500
    Abstract: 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.

  • Patent number: 6026291
    Abstract: 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.

  • Patent number: 4483049
    Abstract: 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.
