Patent WO-9954073-A1 (WO)
Title: Plaque bimetallique
Inventor: HEIJKOOP TEUNIS
IPC: B22C9/22
Filed: 1999-04-16
Abstract: Afin de produire une plaque bimétallique, on préchauffe un substrat (S) constitué d'un premier métal ; on le positionne dans une cavité (34) de moule de façon à diriger sa surface principale vers le haut et à remplir une partie de la profondeur de ladite cavité (34) ; puis on coule un second métal sur ladite surface de façon à constituer un composant placage et, avec le substrat (S), à former une plaque bimétallique. Avant de couler le placage, on élimine sensiblement tous les oxydes de la surface principale et on la protège contre l'oxydation. On coule le placage avec un bain d'une composition nécessaire audit placage, que l'on verse à une température de surchauffe de façon à obtenir, avec le préchauffage du substrat (S), un équilibre énergétique thermique global entre le substrat et le placage. L'équilibre thermique entraîne la réalisation de la liaison par diffusion entre la surface principale du substrat et le placage. L'obtention dudit équilibre est facilitée par le fait que le bain pénètre dans la cavité (34) du moule par une série d'attaques (44) qui permettent la communication entre au moins un canal de coulée (40) et ladite cavité. Les attaques (44) sont disposées latéralement par rapport à l'écoulement du bain, qui forme un front de bain s'étendant latéralement. L'obtention de l'équilibre thermique est également facilitée par le fait que le front du bain avance en s'éloignant des attaques (44), à la surface du substrat (S), à une vitesse sensiblement uniforme sur toute son étendue latérale.

Title: Procede et appareil permettant d'afficher des hierarchies de contenances et de naviguer dans celles-ci
Inventor: ROCHFORD SUZANNE L
IPC: G06F3/033
Filed: 2000-05-19
Abstract: La présente invention concerne un procédé destiné à un système informatique permettant d'afficher un groupe de contenances tel qu'une hiérarchie de dossiers de fichiers. Ce procédé affiche une hiérarchie directe de contenances destinée au groupe de contenance ou aux dossiers de fichiers sélectionnés, de même qu'il affiche une liste des contenus de ce groupe ou de ce dossier. Une hiérarchie directe de contenances ne classe que des dossiers ou des groupes de contenances qui contiennent directement ou indirectement le groupe ou le dossier sélectionné. C'est ainsi qu'un grand nombre de dossiers ou de groupes de contenances qui au bout du compte ne contiennent pas le dossier ou le groupe de contenances sélectionné ne sont pas affichés, simplifiant ainsi l'affichage, et permettant de montrer la hiérarchie directe de contenances dans son entier, sur un seul écran, sans qu'il soit nécessaire de faire défiler l'écran pour obtenir ou vérifier le contexte du dossier de fichiers ou du groupe de contenances donné.

Inventor: NOE JAMES B
IPC: C04B35/52
Filed: 1989-11-22
Abstract: A method of sealing the surfaces of porous carbon and graphite articles by impregnation at ambient pressure using a treating solution comprising a high temperature polymerizable liquid resin.  The liquid treating solution, when upon the surface of the article, is of sufficiently low viscosity to allow infiltration of the treating solution into the pores of the surface of the article.  The treated article then undergoes a controlled heating cycle, which cures the infiltrated resin in situ.  Subsequent treatments and surface conditioning techniques are utilized to produce a thin, level, liquid and gas impervious coating on the surfaces of the article.

Title: Adjustable merchandise display bracket locking system
Inventor: COHEN MAURICE
IPC: A47B96/06
Filed: 1989-12-14
Abstract: ABSTRACT           A shelf or hanger mounting bracket which comprises an inner bracket body having one end provided with projections configured for locking engagement with vertically extending slits in a wall-mounted upright mounting rail and an ornamental outer sleeve comprising a locking system enabling the sleeve to be continuously adjustable over a range of positions so that it can be adjusted to lie flush with the mounting wall.  The locking system employs a latching member pivotally mounted on the forward end of the inner bracket body having a locking end slantingly engaging the confronting interior wall surface of the sleeve so that forward retracting movement of the sleeve cannot occur as long as the locking end is held in contact with this sleeve surface.  Slipping rearward movement towards the wall readily occurs.  In the preferred form of the invention the latching member has a release end extending forwardly of the pivot and having sufficient weight that the locking end is continually forced into engagement with the sleeve inner surface.  An aperture in the bottom of the sleeve permits insertion of a pencil or similar object to bear against the release end so as to raise it, thereby rotating the locking end out of engagement, permitting limited withdrawal of the sleeve so that the bracket assembly can be removed from the mounting rail.

Title: Aquatic exerciser
Inventor: SILVESTRI CLAUDIO
IPC: A63B21/068
Filed: 1990-02-12
Abstract: ABSTRACT OF THE DISCLOSURE          The present invention relates to an aquatic exerciser or rehabilitation equipment and, particularly, to an exerciser mounted for positioning a user engaging component in a cantilevered configuration over the edge of a swimming pool or other water body.  The exerciser suspends user engaging members over the water and allows the user to carry out various exercises within the pool. Typically, the exercises include body lifting exercises and in Contrast to conventional body lifting exercises carried out outside the water, the force required by the user increases in proportion to the amount of his body that is above the water level.  In other circumstances the difficulty may be increased by carrying out certain movements within the water at higher speeds with the water providing a drag force as an increasing function of the speed.  Thus, the user can either increase or decrease the difficulty of the exercise easily.
