摘要： In order to produce a cellulose moulded body, a solution of cellulose in a tertiary amine oxide is moulded in the warm state and the solution thus moulded is fed into a precipitation bath after coding to precipitate the cellulose contained therein. Coding takes place immediately after moulding and is done preferably by blowing air horizontally onto the cellulose moulded body. The process according to this invention facilitates spinning of the cellulose solution with a high yarn density while preventing jamming of the spun yarns when leaving the spinning nozzle. It also allows, despite the high yarn density, a large air gap to be left between the spinning nozzle and the precipitating bath, which leaves adequate time to modify the textile characteristics of the yarns by drawing them as they leave the spinning nozzle.
摘要翻译：为了制造纤维素成形体，在温热状态下将纤维素在叔胺氧化物中的溶液成型，将这样成型的溶液进行编码后的沉淀浴中，使其中含有的纤维素析出。编码在模制之后立即进行，并且优选通过将空气水平地吹送到纤维素模制体上来进行。根据本发明的方法有助于以高纱线密度纺丝纤维素溶液，同时防止纺丝纱线离开纺丝喷嘴时的干扰。即使纱线密度高，纺丝喷嘴和沉淀槽之间仍然留有大的气隙，这样留下足够的时间来通过在离开纺丝喷嘴时将丝线的纺丝特性拉出来。

摘要： The invention relates to a device for filtering a fluid, and is characterised by: a housing consisting of two components (1a, 1b) which are firmly connected but spaced apart from each other. The first component (1a) has an inflow canal (6) for the fluid that is to be filtered, and the second component (1b) has an outflow canal (18) for filtered fluid; a piston (4) which is movably accommodated in the housing and has a front valve (7), a filter (9), a valve (10) and a rear valve (11). The filter is placed after the front valve and before the rear valve, and the valve body has a collecting channel (13) for filtered fluid that is in connection with the filter and with a filtrate zone (14), which is included in the second component (1b) of the housing and connects to the outflow canal (18).
