Abstract: A disposable absorbent hygiene product is provided, including a main part having a body facing surface intended to face the body of a user and a garment facing surface intended to face away from the body of a user. The main part includes a liquid permeable topsheet at the body facing surface, a liquid impermeable backsheet at the garment facing surface, and an absorbent assembly arranged between the topsheet and the backsheet. The liquid permeable topsheet material includes a hydrophilically treated polypropylene spunbond nonwoven or spunbond/meltblown composite nonwoven, having a basis weight of from 8 to 20 g/m2. An acquisition layer material is provided sandwiched between said topsheet and said absorbent assembly, being an through air bonded nonwoven.

Abstract: A support arm arrangement for a local gas extractor arrangement and a local gas extractor arrangement including such a support arm arrangement. The support arm arrangement includes a first support arm and at least one second support arm being pivotally coupled to each other by friction joint arrangements. The support arm arrangement receives a tube device coupled to an extractor hood, an exterior pump device and the support arms. The extractor hood is arranged at an outermost second support arm by a linkage arm arrangement including a first link arm pivotally coupled to the outermost second support arm by a first friction joint pivotable about a first pivoting axis, and a second link arm fixedly attached to the extractor hood and pivotally coupled to the first link arm by a second friction joint pivotable about a second pivoting axis extending in a direction perpendicular to the first pivoting axis.

Abstract: A torque transmitting assembly for a power tool comprising an angle head having a first output shaft which is rotational about a rotational axis and arranged to be connected to a power tool motor for transmitting a rotational movement from the motor to the first output shaft; a power tool attachment part having an input shaft connectable to the first output shaft, a second output shaft and a gear arrangement for transmitting rotational movement from the input shaft to the second output shaft; and fixation means for fixation of the attachment part to the angle head. The fixation means comprises first fixation means arranged to prevent axial displacement of the attachment part relative to the angle head; and second fixation means arranged to prevent rotation about the rotational axis of the attachment part relative to the angle head, which second fixation means is separate from the first fixation means.

Abstract: A fuel assembly for a boiling water reactor having fuel rods, two or three water rods, a tie plate, spacers, a handle, and a joint arrangement. The joint arrangement is configured to transfer a vertical lifting force from the handle to the water rods. The joint arrangement includes a balancing element arranged between the water rods and the handle. The joint arrangement includes a first joint arranged between the balancing element and the handle and a set of second joints arranged between a respective one of said water rods and said balancing element. The first joint and the set of second joints are configured to allow a rotational movement of said balancing element in relation to said handle as well as in relation to said water rods in order to balance lifting forces in the water rods.
