Abstract

1,243,065. Suction dredgers. INGENIEURSBUREAU VOOR SYSTEMEN EN OCTROOIEN SPANSTAAL N.V. 9 Oct., 1968 [16 Oct., 1967], No. 47920/68. Heading E1F. In a suction dredger where the suction pipe comprises an upper portion 5 of smaller flow section than a lower portion 7 there is provided at the lower end of the upper portion 5 a flange 6 that extends at right angles from said portion to or adjacent to the interior wall of the lower portion 7 to form a throat 2 in the suction pipe. The throat 2 so formed causes, when flow occurs up the pipe creation of a vortex 4 that facilitates flow from the lower portion 7 to the upper portion. The creation of a satisfactory vortex 2 may be aided by the admission of water through an annular gap between the flange and the interior wall of the lower section when the flange only extends to adjacent said interior wall.
