Abstract: Selon l'invention, un premier élément d'arrêt (74) est relié à un élément de cadre (72) longitudinal et s'étend vers le haut de manière perpendiculaire par rapport à celui-ci (72). Un second élément d'arrêt (80) est relié à un élément de base (82) et se projette vers le haut de manière perpendiculaire par rapport à celui-ci (82). L'élément de base (82) est supporté par l'élément de cadre (72) et est guidé le long de celui-ci par une nervure longitudinale (84) située sur l'élément de cadre (72) et par un évidement longitudinal (86) formé dans le fond de l'élément de base (82). Les éléments d'arrêts (74, 80) comprennent une tige recevant des ouvertures (78, 120). Une partie avant d'une tige rotative (12) se projette vers l'avant à travers l'ouverture (78) dans l'élément d'arrêt avant (74) et puis se projette en avant à travers un passage guide dans un élément guide (52) présentant une surface terminale avant (53). Une partie arrière de la tige (12) se projette à travers l'ouverture (120) dans l'élément d'arrêt arrière (80). La tige (12) comprend une butée (46) placée entre les deux éléments d'arrêt (74, 80). L'élément de pointe tranchant (14) est relié pivotant à l'extrémité avant de la tige (12). Lorsque l'élément de pointe tranchant (14) est utilisé, il est orienté de manière à être coaxial par rapport à la tige (12) et est déplacé dans une ouverture à accès percutané formée dans une partie du corps (   ). La tige (12) et l'élément de pointe tranchante (14) sont tournés par rapport aux éléments d'arrêt (74, 80), entraînant le déplacement de l'élément de pointe tranchante (14) vers l'extérieur et la découpe d'une cavité dans la matière corporelle dont le rayon est supérieur à celui de la tige (12). Un mouvement avant de la tige, destiné à déplacer la butée (46) contre l'élément d'arrêt avant (74), déplace l'élément de pointe tranchante (14) vers l'emplacement d'une délimitation souhaitée de la cavité. Un mouvement de la tige (12) vers l'arrière, destiné à déplacer la butée (46) de manière qu'elle soit en contact avec l'élément d'arrêt arrière (80), déplace l'élément de pointe tranchante (14) vers l'emplacement d'une seconde délimitation terminale de la cavité.

Abstract: An ophthalmic lens, such as multifocal contact lens, that is worn on the surface of the eye and has a blended design for a segmented optical zone. The lens has an anterior surface and an opposite posterior surface, wherein the anterior surface includes a vertical meridian, a horizontal meridian, a central optical zone having at least a first optical zone for primary gaze, a second optical zone for down-gaze and an optical blending zone between the first and second optical zones. The optical blending zone has a surface that ensures a smooth surface transition from the first optical zone to the second optical zone and that allows the first and second optical zone to be designed independently and optimally so that ghost images or blur from the transition between the first and second optical zones can be minimized or eliminated. Image blur from the blend zone that subtends the pupil is minimized by the magnitude of the curvature of the blend zone. The optical zones will have the optimal aberration parameters to control vision.

Inventor: BURR JOHN D
IPC: A61M15/08
Filed: 2002-11-14
Granted: 2011-01-04
Abstract: An aerosolization apparatus (100) comprises a body (105) having an inlet (130), an endpiece (110) having an outlet (125), the endpiece being connectable to the body to define a chamber, wherein the chamber (115) is sized to receive a capsule containing a pharmaceutical formulation in a manner which allows the capsule to move within the chamber. The apparatus further includes a connection mechanism (150) to provide selective connection of the endpiece to the body, wherein a rotational force between the endpiece and the body is needed to connect or disconnect the endpiece from the body, the rotational force being applied about an axis passing through the chamber. When a user inhales, air enters into the chamber through the inlet so that the pharmaceutical formulation is aerosolized within the chamber and the aerosolized pharmaceutical formulation is delivered to the user through the outlet. The connection mechanism prevents inadvertent disconnection of the endpiece from the body.

Abstract: Cet extrait concerne un processus pour lixivier un métal précieux de minerai contenant des sulfures de métaux de base, comprenant l'étape de lixiviation du minerai avec un lixiviant contenant un chlorure, un oxydant et de l'acide chlorhydrique. La lixiviation est contrôlée par l'utilisation d'acide chlorhydrique de faible concentration et d'un potentiel d'oxydo-réduction, pour former du sulfure d'hydrogène à partir du minerai contenant des métaux de base. Le sulfure d'hydrogène est lessivé par la solution de lixiviation, ce qui réduit la quantité de sulfates générée lors du processus à des niveaux très bas. La lixiviation peut aussi être effectuée pour limiter la dissolution des métaux du groupe du platine et de l'or avec les métaux de base. La lixiviation forme un lixiviat riche en métaux précieux et un résidu solide. Le résidu solide peut par la suite être lixivié pour récupérer les métaux du groupe du platine et de l'or. Le lixiviat riche en métaux précieux peut être oxydé et neutralisé pour récupérer des métaux précieux de base. Dans une réalisation, le chlorure est un chlorure de magnésium et la solution lixiviante est régénérée.
