Abstract
1484588 Dripper tube for irrigation J SAHAGUN - BARRAGAN 15 Nov 1974 49598/74 Heading F2P [Also in Division A1] A dripper tube for irrigation comprises a pipe co-operating with a plurality of members to form a plurality of passages each supplied with liquid by a hole in the pipe 1 and discharging liquid from an outlet hole, each passage being provided with internal baffles projecting transversely from either side of the passage to obstruct the liquid flow and thereby reduce the pressure at the outlet hole. In Figs. 1 or 2, the pipe 1 has attached to it a continuous channel member 12 partitioned to form a number of separate passages 14 which are provided with baffles 13, each passage 14 being supplied via hole 16 and discharging via hole 17. In Fig. 3 (not shown), the baffles 13 are in the form of tapering teeth; in Fig. 4 (not shown), baffles 13 are also formed on a central member extending along the passage 14, and the holes 16, 17 are at the centre of the passage 14. The pipe 1 may comprise two strips joined at their edges, or a single strip bent over so that its edges can be joined. The channel member 12 may be inside or outside the pipe 1. The pipe 1 adopts a cylindrical shape when liquid flows in it. In Fig. 12, the passage is formed by a projection 29 and a strip 30. The projection 29 may be within the pipe 28 and the outer wall of the passage be formed by the strip 30. In Figs. 15-17 (not shown), the channel member may be bonded by peripheral flanges to the pipe 1 to form a single passage, the baffles extending initially across and then along the passage, alternately forwards and backwards.
