Abstract: An absorbing product comprising a substantially cylindrical cartridge of a web material (13) with a first inner layer (25) and an intermediate layer (24) which merge into each other at a twisted portion (19) at one end of the cartridge, and a third outer layer (27) which connects to the first layer at another twisted portion (26) at the other end of the cartridge. The inner layer defines a closed cavity between the two twisted portions. The invention also relates to method and apparatus for manufacturing the product. The apparatus has a cylindrical mandrel having two co-axially spaced elements (12A, 12B) which are individually rotatable. In one element there is provided a co-axially displaceable member (20) forming a cavity (21) open towards the other element which is tubular to receive the axially displaceable member with a surrounding gap. A pressure member (23) is axially displaceable through said other mandrel element into the cavity.

Abstract: A device for transmitting linear measuring motion comprises a U-shaped element and a T-shaped element, the stem of which is received between the limbs of the U-shaped element. The elements are connected for relative axial displacement and rotational motion by means of a ball bearing. Rotational motion is prevented by an anti-friction bearing between the elements. The elements are biased against each other over the anti-friction bearing accurately guiding the elements for relative axial displacement thereof.

Abstract: PCT No. PCT/SE78/00075 Sec. 371 Date July 10, 1979 Sec. 102(e) Date July 10, 1979 PCT Filed Nov. 13, 1978 PCT Pub. No. WO79/00291 PCT Pub. Date May 31, 1979An apparatus for indicating inside dimensions comprises a base plate and a supporting plate spaced above the base plate for the object to be measured. Aligned rails displaceable in relation to each other are provided on the base plate and extend along slots in the supporting plate, said slots extending radially in relation to a center. Measuring arms project upwards from the rails through the slots which also form guides for securing supports for the object to be measured on the supporting plate. The rails are operatively connected to indicating members for transmitting measuring motion from the measuring arms to the indicating members.

Abstract: A gauging frame for transmitting measuring movements comprises two bar elements allowing components to be mounted thereto individually and each independently of other components by engagement with the bar element transversely thereof.
