Abstract: GUIDE A FENTES RAYONNANTES NON INCLINEES EXCITEES PAR DES VOLETS METALLIQUES L'invention concerne un guide à fentes rayonnantes non inclinées excitées par des volets métalliques. Dans un guide d'ondes (1) comportant des fentes (2, 3) perpendiculaires à l'axe du guide découpées dans un petit côté du guide, on dispose de part et d'autre de chaque fente des paires de volets métalliques (21, 22; 31, 32) symétriques par rapport à l'axe central (XX') de la fente. Ces volets modifient le champ électrique au niveau de la fente associée et permettent de l'exciter, la valeur du couplage étant réglée en ajustant la taille des volets et leur position par rapport à la fente rayonnante correspondante. L'invention s'applique aux guides à fentes, notamment pour antennes réseaux. Figure 1

Title: Submerged breakwater for use as a perch for sand retention
Inventor: CRETER RICHARD E
IPC: E02B3/06
Filed: 1993-04-02
Abstract: SUBMERGED BREAKWATER FOR USE AS A PERCH FOR SAND RETENTION                       Abstract A breakwater that is formed from a plurality of modules, with each module including a base suitable for supporting the module on the seabed, a gently sloping seaward face extending above the base from one end, and a sloping beachward face extending above the base from the opposite end.  The tops of the seaward and backward face meet to form a top section and at the top portion of the beachward face at the top section there is a transversely disposed concave cutout that extends across the beachward face.  The cutout causes backwash water to swirl in it which removes a significant amount of the nourishment sand that is in backwash water.  The cutout has two spaced apart vertically extending concave channels that connect to respective openings in the top of the module. The concave channels direct backwash water through the openings in the top of the module and these high pressure streams allow backwash water to pass seaward over the breakwater but significantly reduces the amount of nourishment sand in the backwash that passes over the breakwater to seaward.
