Abstract: An assembly (100) for adjusting the size of a spacesuit and/or for relieving tension applied to the spacesuit is provided in which first and second members (102,104) slide relative to one another along a longitudinal axis (106) to vary the assembly's length. The members (102,104) define a first region (116) which is internal to both members and which changes in volume as the length of the assembly is varied and a second region (118) which is external to the first member (102) and internal to the second member (104) and which also changes in volume as the length of the assembly is varied. The first and second regions (116,118) are connected to one another by a gas conducting path (120). These regions (116,118) have sealed cross-sectional areas which are substantially equal to one another. In this way, pressurization of the spacesuit produces no net sliding motion of the first and second members (102,104) along the longitudinal axis (106).

Abstract: A method of operating a draw frame including a plurality of serially arranged roll pairs each defining a nip through which a fiber sliver passes from roll pair to roll pair. Each roll pair is formed of an upper roll and a lower roll. A pressing arm carries the upper rolls, and pressing devices are accommodated in the pressing arm for pressing each upper roll against a respective lower roll. The method comprises the following steps: during the working state of the draw frame, passing the sliver consecutively through the roll pair nips while the pressing devices press the upper rolls against respective lower rolls, and during an interruption of the working state the upper output roll is relieved of pressing forces to an extent that at the most only an insubstantial pressure is exerted by the upper output roll on the sliver situated in the nip between the upper output roll and the lower output roll.
