Abstract
1354375 Melt distribution apparatus BARMAG BARMER MASCHINENFABRIK AG 3 May 1971 [6 May 1970] 12808/71 Heading B5B [Also in Division F2] Apparatus for distributing highly viscous liquids, particularly polymer melts prior to melt spinning, comprises at least one individually disconnectible positive source and a plurality of negative sources or at least one negative source and a plurality of positive sources arranged in at least one ring conduit in such a way that the fall or rise in pressure from each of two adjacent sources of similar type that are in operation to any other source of the other type is different, shut-off members for the/or each negative and positive source being situated in the/or each ring conduit and being adapted so as to allow flow of the viscous liquid in the conduit in both their open and closed positions. In the simplest embodiment of the apparatus (Fig. 1) two positive sources 1 and 2 and one negative source 3 are arranged in ring conduit 4 so that the fall in pressure between positive source 1 and negative source 3 is not equal to the fall between positive source 2 and negative source 3 thus ensuring a flow between sources 1 and 2 as well as from each positive source to the negative source both when one of the positive sources is disconnected (Fig. 2, not shown) and when both are operating. In other embodiments (a) a plurality of positive sources are arranged in one ring conduit and are connected to a plurality of negative sources arranged in a second ring conduit by connecting pipes (Figs. 5 and 6, not shown) and (b) a single positive ( or negative) source is connected to a ring conduit containing a plurality of negative (or positive) sources by as many connecting pipes as there are sources in the ring conduit (Figs. 3 and 4, not shown). The shut-off members are preferably disc valves (see Division F2) which both in their completely open and completely closed position allow flow in the ring conduit. The apparatus avoids the creation of undesirable "dead spaces" inherent in prior art distribution apparatus.
