摘要:
A warp formed of a multiplicity of parallel filaments is wound on a warp beam by an apparatus having a supply of the warp, a transport roller, and an adjustment roller adjacent the transport roller and movable between a holding position engaging the transport roller and a winding position spaced therefrom. The warp extends from the supply along a path around the transport roller, hen around the adjustment roller, and then around the warp beam. The beam and transport roller are rotated to displace the warp along the path and wind it up on the beam while maintaining the adjustment roller in the winding position. Tension is detected in the warp at least during winding of the warp on the beam and the adjustment roller is displaced during winding of the warp on the beam in a predetermined first direction transverse to the path to increase and decrease the tension to maintain the tension within a predetermined range when the adjustment roller is not in the holding position. The beam and transport roller are arrested to stop winding of the warp and the adjustment roller is pressed in a second direction transverse to the first direction against the transport roller into the holding position to stabilize the stopped warp.

The invention relates to an isokinetic gantry arrangement for the isocentric guidance of a particle beam (12), that can be rotated about a horizontal longitudinal axis (16) and has a beam optical system, symbolized by magnets (36, 38, 40), that deflects the particle beam (12) axially infected by a particle beam accelerator, radially and vertically relative to the horizontal longitudinal axis (16), with a largely rotationally-symmetrical primary structure (18) and a secondary structure (30) that holds the magnets (36, 38, 40) and is supported by the primary structure (18), with the secondary structure (30) having a rigidity that is designed so that the vertical displacements of the magnets (36, 38, 40) due to their weight are essentially of equal magnitude (isokinetic) in all the angle of rotation positions of the gantry arrangement (10), and a method for its design.
摘要:
A process for applying indigo dyestuff on a textile substrate is described, wherein the substrate is saturated with liquid steeping liquor containing indigo dyestuff and the saturated substrate is directly passed through a first low-oxygen wet dwelling section and only thereafter is dewatered. To maximize the dyestuff yield or diffusion into the individual fibers of the substrate, a second enclosed low-oxygen wet dwelling section is defined by an essentially sealed housing which is connected to the first wet dwelling section. The substrate is initially heated in the second wet dwelling section and the substrate travels through the remainder of the second wet dwelling section for a sufficient time to permit diffusion of the dyestuff into the fibers of the still moist substrate.
