Inventor: VO THUAN QUANG
IPC: B60R1/10
Filed: 1995-09-15
Abstract: The front view vehicle mirror system (FVVMS) is a mirror assembly mounted on a vehicle to provide vehicle operators with an alternative view of objects ahead that are obstructed by some darken vehicles, such as a tinted car, van, truck, or trailer. The FVVMS includes a plastic or plastic-like case enclosing two periscopic mirrors, one is standard and the other is convex, a solid mounting base attached near a front corner of the vehicle to support and fasten the FVVMS to the vehicle. The FVVMS mounted at thefront end on the driver side is particularly useful for the operator to make a safe left turn ( in right-hand-driving-rule countries)at intersections, and the FVVMS on the passenger side is helpful for the driver to view front objects or road condition ahead when he is trapped in traffic jams or on busy highways. That is, FVVMS provides drivers with an alternative way of observing front objects,while their direct line of sight is blocked by a view obstructing vehicle.

Title: Five-piece container with hingeable sides
Inventor: JACQUES MICHEL
IPC: B65D6/18
Filed: 1996-07-09
Abstract: A five-piece container for items, such as bottles, comprises a bottom piece, a pair of side pieces of identical height and a pair of end pieces also of identical height; each side edge and each end edge of the bottom piece display a series of planar surfaces interspaced with a series of recessed areas in which is defined a hinge that engagedly receives a C-shaped extension formed at the lower edge of each side piece and of each end piece so that the side and end pieces may be mounted to the bottom piece through a snap . The end pieces and the side pieces can be moved between an outward foldback position and an erected position; however, an inward folded position cannot be effected due to the configuration of the lower edge of the side pieces and of the end pieces and that of the edges of the bottom piece. The folding configuration is useful for containers that have walls higher than the width of the bottom thus preventing the walls from being folded inside.

Abstract: L'invention concerne des préparation de conjugués d'un facteur de croissance des fibroplastes et d'un agent ciblé, ainsi que des composition contenant lesdites préparations. Lesdits conjugués contiennent un polypeptide réagissant avec un récepteur du facteur de croissance des fibroplastes FGF tel que le bFGF ou tout autre facteur FGF couplé à un agent ciblé au moyen d'un segment de liaison. Le segment de liaison est sélectionné pour augmenter la spécificité, la toxicité, la solubilité, la stabilité sérique, et/ou la disponibilité intracellulaire de la fraction ciblée. On peut utiliser plusieurs segments de liaison de manière à tirer profit des propriétés voulues de chacun d'eux. L'invention porte également sur des compositions pharmaceutiques contenant ces conjugués de FGF et un agent ciblé, ainsi que sur des méthodes de prévention de la récurrence de ptérigions, de la fermeture d'une trabéculectomie et de l'opacification de la cornée comme suite à une chirurgie au laser excimère. Lesdites méthodes consistent à mettre la zone de l'oeil ayant été traitée chirurgiquement en contact avec la composition pendant ou immédiatement après l'intervention chirurgicale. L'invention se rapporte aussi à des compositions de conjugués du facteur de croissance des fibroplastes et du domaine de liaison de l'acide nucléique. Lesdits conjugués fixent les molécules d'acide nucléique par l'intermédiaire du domaine de liaison de l'acide nucléique. Ces conjugués peuvent être utilisés pour libérer un acide nucléique codant une protéine cytotoxique ou un acide nucléique antisens et similaire dans des cellules exprimant les récepteurs du facteur de croissance des fibroplastes.

Title: Catheter convertible from rapid exchange mode to over the wire
Inventor: ANDERSEN ERIK C
IPC: A61F2/958
Filed: 1995-03-23
Abstract: A stylet (26) and hub (36) assembled for stiffening a catheter (10) in rapid exchange mode. The catheter guidewire lumen (20) has a side port (22) associated with a bi-stable guide element (24) that lies across the lumen. A disengageable feature assembly (38) limits insertion of the stylet into the lumen in rapid exchange mode. To convert from rapid exchange mode, disengagement of the disengageable feature enables the stylet to displace the guide element, clearing the guidewire lumen and enabling guidewire or other device to extend throughout the lumen. The stylet has a long proximal portion (34), a relatively short portion (32) tapering distally to a smaller diameter, and enlarged end (34). The guide element is formed by plastic deformation of the catheter wall. The disengageable feature is in a removable housing (28) having an end cap (54) that can be replaced with a syringe for flushing liquid along the stylet. A balloon (12), preferably a PTCA balloon, is mounted on the catheter.

Abstract: An edible oil composition includes at least a major proportion of an edible bulk oil, and a second oil constituent combined therewith for increased stability. The second oil constituent is a sesame oil, preferably extracted and refined in a manner preserving substantial concentrations of antioxidant factorspresent therein. The bulk oil is preferably high in monounsaturated content, and is conveniently one of any available oils such as, for example, High Oleic Sunflower Oil, having a monounsaturated fatty acid content in a range of about 70% or greater, and having a maximum of about 10% saturated fatty acids. Advantageously, the linolenic acids content should also not exceed 3%. Optionally, the composition may contain a third oil constituent in a minor proportion, the oil being selected from a group of oils high in .DELTA.-5 avenasterol, such as, for example rice bran oil or oat oil. The third oil constituent functions to inhibit polymer formation and is believed to neutralize odors and flavors caused by undeodorized sesame oil, permitting the use of higher concentrations thereof.

Title: Fastener for use on a protective helmet
Inventor: CHARTRAND DANIEL
IPC: A42B3/20
Filed: 1996-12-13
Abstract: A protective helmet, comprising an outer helmet shell of rigid material and having a fastener mounted into the outer helmet shell. The fastener comprises a rivet and a washer.  More particularly,  the rivet includes a flanged head portion at a first end of the rivet, a post part at a second end of the rivet, and  a  section  having  an  obround  cross-sectional  shape intermediate the flanged head portion and the post part.
