Abstract: During the relative displacement between a warping stand with a warping drum and a beaming stand with a warp beam for rewinding a thread group, mutual support takes place at a supporting bearing. In this way, very high warp tensions can be adopted, without the risk that the warping stand will tilt and without the latter having to be loaded with additional weights.

Abstract: The yarn sheet (1) of a finished yarn winding (2) for example on a warping machine is with the help of a transfer means (8) transferred onto a winding beam (3) for example of a beaming machine. The transfer means with this has a suspension rod (9) which preferably can be displaced on a transport chain pair (10) along an advance path from the region of the yarn winding (2) to the region of the winding beam (3).

Abstract: After yarn breakage, yarn loops are formed in an accumulator device (3) by rollers (13, 13') that are able to be displaced in relation to each other. The beam is rotated in reverse at a specific reverse speed (c) which is less than the accumulation speed of the accumulator rollers (13, 13'). The length difference arising from the difference between both the speeds is compensated by further withdrawal of yarns (a) from the creel (1) while the yarns are subjected to a defined braking tension of the individual yarn tensioners (7). Complex controls and speed synchronization are thus avoided.

Abstract: The invention relates to a composition for carrying out a uric acid load t for the differential diagnosis of diseases of the purine metabolism. The composition comprises a mixture of adenine and guanine, preferably in equal quantities, incorporated in a carrier, preferably comprising amorphous silicic acid.
