Abstract: The body, used as a fin or center board for a sailing boat, has a horizontal cross section asymmetrical with respect to the vertical longitudinal center plane (18) of the boat, so as to provide a lateral thrust component, and is comprised of at least two portions (14, 16) arranged one behind the other in the headway direction. The front portion (14) has a neutral cross section having the shape of a drop symmetrical to said plane whereas a rear portion (16) arranged on the leeward side of the center plane, has a substantially triangular cross section and gets closer with its anterior side to the front portion of the body so as to complete the drop shape of the latter to obtain an asymmetrical thrust section. The rear portion of the body may be comprised of one of the two retractable center board halves, of which only the one which is on the leeward side is lowered, and there may be a traversing slot (20). The front portion of the body may be shaped as a retractable ballast keel and may be retracted, with the half of the rear portion which is lowered, by means of a cable which is also used to retract only the rear half.

Abstract: In apparatus for the reverse osmosis purification of water or other fluid in a module (10) containing a membrane (11), the water is forced into the module (10) underpressure using two or more piston-cylinder assemblies (25, 26) mechanically interconnected with the pressurised fluid from the module applied to the rear face of the piston (27 or 28) which, from its front face, is driving water into the module, a low pressure continuously operating pump (20) providing a low pressure on the other piston to supply the necessary extra pressure. Valve means (30, 31, 33, 34) automatically reverse the functions of the two cylinders at each end of each stroke. This arrangement obviates any need for a mechanical drive to the pistons of the piston-cylinder assemblies (25, 26).

Abstract: Systeme de simulation de tir pour l'entrainement et l'evaluation de la precision du tir sur un avion, dans lequel une unite d'affichage (24) utilise un tube a rayons cathodiques (26) pour projeter des balles simulees sur un tableau de visee d'un pilote (22). Une paire d'indices de repere de trajectoire des balles est associee a chaque balle simulee pour simuler le tir de l'avion sur une cible donnee, telle qu'un avion cible. Les indices de chaque paire sont espaces de maniere equidistante de la trajectoire simulee d'une quantite en rapport avec une dimension selectionnee de la cible. Chaque paire d'indices de trajectoire des balles est affichee initialement pour refleter les conditions physiques de l'avion de tir au moment du tir, comprenant les donnees du triedre de reference de l'avion, la portance et l'acceleration de l'avion, la vitesse reelle de l'avion dans l'air, l'angle d'attaque du canon, et la densite relative de l'air. Au fur et a mesure que les indices de la trajectoire des balles traversent le chemin de trajectoire simule, la separation entre les indices d'une paire diminue, pour simuler une distance croissante a partir de l'avion de tir. Une cible est touchee lorsqu'une paire d'indices de trajectoire de balles recouvre la cible, et les indices dans la paire sont separes d'une distance egale a la dimension de la cible choisie.
