Patent CA-2321441-A1 (CA)
Title: Retracting needle syringe
Inventor: CAIZZA RICHARD
IPC: A61M5/32
Filed: 1999-12-02
Abstract: The syringe has a re-use prevention feature where the plunger rod (26) and needle hut (38) are destroyed and the needle (64) is retracted into the rod. This feature requires only an increase of force along the same line of action as the injection stroke. This allows for safe, one-handed injection, which is critical in some situations. The syringe also minimizes the amount of wasted medication because the plunger rod tip (28) occupies the entire volume inside de the barrel (20). The retracting needle syringe uses standard luer-lok fittings and can be used with a variety of standard needles that do have rectracting cannula. A large gauge needle can be used to fill the syringe from a vial or other container before attaching the savety needle for injection.  Lastly, the plunger can be completely encapsulated by the barrel prevents re-use of the syringe and allows for safe and easy disposal.

Title: Systeme de pile a combustible liquide
Inventor: LAMM ARNOLD
IPC: H01M8/04223
Filed: 1999-02-23
Abstract: L'invention concerne un système de pile à combustible comprenant au moins une pile à combustible (10) présentant un espace anodique (12) et un espace cathodique (14), séparés l'un de l'autre par une membrane conductrice de protons (16). Ce système comprend une conduite d'alimentation cathodique (20) pour acheminer du gaz contenant de l'oxygène jusqu'à l'espace cathodique, une conduite d'alimentation anodique (18) pour acheminer un mélange liquide agent de refroidissement/combustible jusqu'à l'espace anodique, ce dernier se trouvant dans un circuit anodique comprenant un séparateur de gaz (52) et une pompe (34). Le mélange agent de refroidissement/pile à combustible qui circule dans le circuit anodique est refroidi par la pile à combustible, qui est conçue pour fonctionner avec un passage d'eau allant de l'espace anodique dans l'espace cathodique. Le refroidissement par évaporation voulu dans la pile à combustible induit ainsi un refroidissement du mélange agent de refroidissement/combustible, à une température de fonctionnement stationnaire qui intervient dans la pile à combustible en fonction des propriétés de la membrane et du régime de la pompe, de manière qu'il ne soit plus nécessaire de placer un refroidisseur supplémentaire dans le circuit anodique même.

Title: Convertible skate
Inventor: PARDO BEATRIZ E
IPC: A63C17/18
Filed: 1999-06-08
Abstract: The convertible skate (1) of the invention includes wheels (258, 268, 358, 368) that are interchangeable between an in-line configuration and a conventional roller skate configuration. The skate (1) can be readily changed between the different configurations by depressing a first button to release a latch and unlock the front pair of wheels (358, 368) from a first configuration. The front wheels (358, 368) can then be rotated into and locked by the latch at their second configuration. The same type of conversion method and apparatus can be used to convert the rear pair of wheels (258, 268) between different configurations. The skate (1) may also include a reverse spinning brake that prevents the skate from rolling backwards. The reverse spinning brake works in either the in-line configuration or the conventional roller skate configuration without requiring any changeover process between configurations.
