Abstract: A method and apparatus for manufacturing a package from a package blank which includes a series of lateral surfaces and end wall sections connected by fold lines are disclosed. The method disclosed includes folding the package blank along fold lines between the lateral surfaces, moving such partially formed package blank along a predetermined path, and rotating the package blank while it is moving along that path while at the same time sequentially folding the end wall sections along a second set of fold lines at one end of the package so as to form an end wall surface at that end.

Abstract: A device for releasably coupling together various objects includes a first profiled tube mounted on a first object, a second profiled tube mounted on a second object to be coupled together with the first object, and a locking rod. The tubes are essentially identical at least in their cross section and have a longitudinal open slot with smaller width than the cross section of the tubes. For coupling, a first circumferential portion of the first tube is inserted through the slot in the second tube, while a circumferential portion of the second tube is inserted through the slot in the first tube. Inside each tube the circumferential portion of the coacting tube is brought into contact with a portion of the interior boundary surface of the respective tube, so that the two tubes will form a sleeve-like unit. The locking rod is inserted into a cavity in this unit to lock the two tubes to each other.

Abstract: A disposable diaper including a first outer layer of a liquid-permeable material intended to abut the body of the user, a second outer layer of a liquid-impermeable material and an intermediate layer of absorbent material arranged between said two outer layers. At least that portion of the diaper, which is situated in the user's crotch, is provided with elastic bands or threads extending between the two side edges of the diaper, these bands or threads being at least partially connected with pretension to the liquid-permeable outer layer.

Abstract: The invention refers to an electronic detector arranged in such a way that the electric conductivity between e.g. a surgeon and a patient can be measured. The detector is preferably placed in the shoes of the surgeon and is through contact members on one hand connected to the surgeon's body and on the other hand to the bedding on which the surgeon stands, preferably a floor having a certain electric conductivity, or a round for this purpose. By the fact that an electrically conductive operating table is electrically connected to the same bedding also the patient will be galvanically connected with said bedding.A detector arranged in this way can detect the conductivity between the surgeon and the patient and makes it possible to control possible biologic leakage, e.g. germ-containing liquid, through perforations in the operation gloves of the surgeon, at which infections in incisions can be avoided to a great extent.

Abstract: The invention relates to a disposable diaper, comprising a layer of a liquid-permeable, preferably non-woven material, intended to be placed in contact with the body of the user, and of a second layer of a liquid-impermeable material, between which layers an absorbent body is arranged, these two layers extending laterally outside the edges of the absorbent body.

Abstract: A method and a device for cutting out pieces of material webs, the cutting taking place between a spherical surface and a sharp edge. The spherical surface consists of a freely movable, non-driven ball. The ball can be made of hard material such as steel and the cutting edge of softer material, or vice versa. The device consists of a roller over which the web is led and a member acting against it. The roller has a groove corresponding to the desired contours of the formed piece. A ball, guided by the groove made in the roller, presses against the edge of the groove for cutting through the web.

Abstract: The invention relates to a tracheal suction catheter comprising a flexible tube whose outermost portion has a side bend forming a knee on the tube, an aperture being provided in the tube wall adjacent the knee.The object of the invention is to provide a construction reducing as much as possible the risk of the catheter being clamped to the mucosa, and according to the invention this is achieved by the tube wall immediately around said aperture being sunk with respect to the cylindrical surface of the tube. Suction from the mucosa is thus spread over a greater area, and the aperture itself is spaced from the mucosa ensuring that the mucosa is not damaged, neither during insertion nor during suction.

Abstract: In a menstrual tampon comprising one or more webs 1, rolled up in several layers around each other, of moisture-absorbing material, a pull string 2 is anchored and extends out of the tampon. This string is laid around the web 1 in at least two consecutive loops which, with portions 6 running back and forth approximately longitudinally to the tampon, surround and are in contact with at least two opposite side edges 7,8 of the web 1 of absorbent material, and extend out of one end of the tampon. (FIG. 2).

Abstract: Improved fluffed pulp consisting of 95 to 25 percent by weight groundwood and 5 to 75 percent by weight chemical pulp, with a liquid retention capacity of at least 6.5 gram liquid per gram pulp, a liquid dispersing capacity of at least 2.5 gram liquid per gram pulp per minute, a bulk of at least 18 cm.sup.3 /gram and a web strength of at least 0.2 Newton, and a method of producing said pulp by mixing 95 to 25 percent by weight groundwood and 5 to 75 percent by weight chemical pulp beaten in a wet state with each other, dewatering mechanically to a dry solids content of 40 to 50 percent by weight, coarse-defibrating, drying in a flash drying step to 60 to 85 percent by weight, finish-defibrating and finish-drying to 80 to 95 percent by weight dry solids content.

Abstract: The present invention relates to fluffed pulp comprising unwashed mechanical pulp with a liquid-diffusing capacity of at least 3.5 grams liquid per gram pulp per minute, a bulk of at least 18 cm.sup.3 /gram and a volume weight in blocks or bales of at most 0.8 grams/cm.sup.3. The invention also comprises a method of producing such a fluffed pulp by means of defibrating the wood and thereafter drying the same with warm air to a dry content of 80-95% by weight without subjecting the pulp to any mechanical compression.

Abstract: A surgical suction device is provided for removing fluid from a wound which device is adapted to be connected to a suction pump by a hose pipe. The device includes a tubular handle and an inner tube extending from one end of said handle. The inner tube is provided with a suction opening at one end and an open tip at its other end. An outer tube surrounds the inner tube to form an annular space therebetween with the inner and outer tubes being movable relative to each other. The outer tube is telescoped over a portion of the handle and includes an aperture normally aligned with an aperture formed in the handle for controlling the suction functions. A plurality of openings is also formed in the space for quickly removing large quantities of fluid from a wound. At one end of the outer tube there is provided a tapered section having a suction opening for contacting the wound and a seat member at its other end.

Abstract: Absorption products such as compresses, sanitary napkins, diapers or the like which comprise an absorption body furnished with a covering and an at least substantially moisture-impermeable layer which is provided between said body and said covering on the side of the body facing away from the user. The at least substantially moisture-impervious layer comprises short hydrophobic fibers loosely applied and essentially unbound to one another.
