  • Publication number: 20020039654
    Abstract: An insulated DC-cable and method for production of an insulated DC-cable with an insulating system comprising an extruded cross-linked polyethylene based insulation disposed around the conductor. The extruded polyethylene based compound comprises additives such as cross-linking agent, scorch retarding agent and antioxidant. The scorch retarding agent comprises a compound (D), 2,4-diphenyl-4-methyl-pentene-1 and the antioxidant comprises a compound (C), a diester of 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionicacid and thiodiglycol. The compounded polyethylene based resin composition is extruded and cross-linked at a temperature and for a period of time sufficient enough to cross link the insulation. The temperature and the period of time upon extrusion and cross-linking are limited so as to substantially suppress or essentially avoid undesired polar by-products being formed in the cross-linked composition.

  • Patent number: 6222481
    Abstract: The present invention relates to a method of detecting and classifying objects using radar. The method means that a broadband radar signal comprising wavelengths that coincide with characteristic lengths of targets to be detected and classified is transmitted. Further, a returned echo signal is received and analysed, at which a signal analysis in a combined time-frequency domain is used, which comprises determining characteristic frequencies in the signal return and their mutual time relations. Finally, a comparison with the corresponding stored values of an analysis of possible targets is performed.

  • Patent number: 6210388
    Abstract: A method of manufacturing an absorbent article in the form of a pants diaper or a sanitary panty starts from a flat blank which includes an elongated absorbent body (5) enclosed between two casing sheets (2, 9) which at opposing front and rear end parts of the absorbent body have side parts which extend laterally beyond the body on opposite sides thereof. The method includes the step of folding the blank about a transverse axis so that the end edges of the side parts lie edge-to-edge. The front and rear side parts of the blank which oppose one another in the folded state of the blank are joined together by a releasable and refastenable fastener (20). A pants diaper can be manufactured in accordance with this method.

  • Patent number: 6152908
    Abstract: An absorbent article having a front part (12), a rear part (14) and an intermediate crotch part (13), such as a diaper, an incontinence guard or like article. The article includes an absorbent body (1), a liquid-impermeable bottom sheet (7) joined to the absorbent body, and a top sheet (9) which is free from connection with the absorbent body over a large part of its surface and which lies proximal to the wearer's body when the article is worn, and which top sheet includes an opening (15) which extends from the rear article part into the crotch part, and elastic devices (24, 25) which are fastened to the top sheet in a stretched state and which when contracting from the stretched state cause the part of the top sheet that is not joined to the absorbent body to be distanced from the body. The top sheet (9) includes a further opening (16) which extends from the front part (12) into the crotch part (13).

  • Patent number: 6149639
    Abstract: The present invention relates to an absorbent article fastener device and to a method for its manufacture. The invention relates to locking elements which are formed with the aid of subpressure, and which are applied fully or partially in-line with the manufacture of an absorbent article. The inventive absorbent article fastener device is designed so that the fastener can only be fastened in one specific orientation, with the fit of the article on the wearer being achieved with the aid of elastic devices.

  • Patent number: 6123692
    Abstract: An absorbent article such as a diaper, an incontinence guard or the like in which the top sheet (1) of the article includes a transverse barrier (11) which divides the article into a rear and a front part (4, 6) and which is intended to prevent faeces discharged to the rear part of the top sheet from moving to the front part thereof. Arranged in the absorbent body (3) essentially opposite the top sheet barrier (11) is a liquid barrier (21) which prevents, either completely or partially, the transportation of liquid in the absorbent body from the front part of the article to the rear part thereof, at least in the layer (18) of the absorbent body that lies proximal to the wearer in use.

  • Patent number: 6120485
    Abstract: A disposable absorbent pants diaper includes an elastic pant provided with holes corresponding to the locations of the anus and the urethral opening when worn. Liquid impermeable layers cover the holes and are sealed to the elastic pant around the holes to thereby form pockets for receiving feces and urine respectively. The pockets also contain absorbent and/or superabsorbent material.

  • Patent number: 5941863
    Abstract: An absorbent article which includes a liquid-permeable outer sheet (1) disposed on a first surface of the article, a liquid-impermeable outer sheet (2) disposed on a second surface of the article, and an absorbent body (3) which is enclosed between the two casing sheets and which includes a receiving space (24) for taking-up body liquid, wherein the space is comprised of at least one cavity or region of lower density than the density of a part of the absorbent body (3) adjacent the receiving space (24) and located generally in the same plane. The article is mainly characterized in that the receiving space (24) is disposed in a storage layer (19) in the absorbent body (3), and in that parts (20,125) of the storage layer (19) adjacent the receiving space (24) include a material which when wetted increases in volume in a direction generally perpendicular to the first surface of the article, whereby the size of the receiving space (24) is also increased in this direction as a result of wetting the article.

  • Patent number: 5928211
    Abstract: A method of elastifying a non-woven or plastic jacket of a pants-type article in its unassembled hour-glass form, arranged end-to-end in a longitudinal web, includes the steps of stretching a web length of elastic net, film or elastomeric non-woven material, which is rectilinear in its unstretched state, transversely but not longitudinally at the two end portions (113) which will form the waist, stretching the length of elastic net, film or elastomeric non-woven material longitudinally but not transversely at the intermediate crotch portion (14) therebetween, whereby the net or film will naturally assume the desired hour-glass shape of the jacket to be elastified, then bonding the stretched net or film in its hour-glass shape to the jacket (5).
