Patent CA-2445058-A1 (CA)
Inventor: CARTER STEPHEN
IPC: F16L41/00
Filed: 2003-10-09
Abstract: A fractional turn fluid joint for a fluid body. The fluid body includes a port which accommodates a tube having a tube shoulder. The port has 2 concentric port bores and a lock bore transverse to the port bores. A lock, placed in the lock bore, includes 2 lock profiles and is rotateably operable between an open and a locked position. One lock profile has a cam profile and the other profile defines a flat catch section adjacent two sections of greater diameter than the catch section. A resilient element is mounted next to the shoulder. In the open position the lock is removable from the bore. In the closed position, the cam of the first lock profile acts on the tubing for preventing removal of the lock and the catch section urges the shoulder against the annulus for a sealed passageway between the fluid body and the tube.

Title: Systeme de culture permettant d'obtenir une expansion rapide de cellules souches embryonnaires humaines
Inventor: GOLD JOSEPH D
IPC: A61K35/12
Filed: 2002-09-05
Abstract: L'invention concerne un système amélioré de culture de cellules souches multipotentes humaines. On cultive généralement les cellules souches multipotentes sur une couche de cellules nourricières (p. ex. fibroblastes embryonnaires de souris) pour éviter qu'elles se différencient. Dans le système décrit, le rôle des cellules nourricières est remplacé par des constituants ajoutés au milieu de culture et qui permettent une prolifération rapide sans différenciation. Le système est caractérisé par une structure support appropriée pour les cellules ainsi qu'un milieu efficace pouvant être ajouté frais à la culture sans nécessiter de traitement préalable par un autre type cellulaire. La culture de cellules souches embryonnaires humaines en milieu frais, mise en oeuvre selon l'invention, permet d'obtenir une expansion étonnamment rapide des cellules et de maintenir la capacité de celles-ci à se différencier en cellules représentant les trois feuillets embryonnaires. Ce nouveau système de culture permet d'obtenir une prolifération globale de cellules pPS à des fins de production commerciale de produits importants pour le criblage de médicaments et la thérapie humaine.

Patent CA-2469103-A1 (CA)
Inventor: MAHVASH MOHAMMADI MOSHEN
IPC: G06F19/00
Filed: 2004-05-28
Abstract: To synthesize the response for a virtual contact resulting from rigid object acting on a deformable body, a method is used whereby the surface of the virtual deformable body carries a finite set of responses corresponding to actual responses between the object and the body which are calculated or measured in a preprocessing step and stored into memory. The virtual deformable body is also meshed into polygons. When an object force interacts with the deformable body, an initial point of contact is made.  The polygon that includes the point of contact is identified and is termed the active polygon. The relative position of the point of contact within the currently active polygon is determined. Response data associated with the currently active polygon is obtained from the memory and the response is synthesized for any point on the surface of the rigid object. The synthesis includes the reproduction of friction. Frictionless contacts are synthesized as a special case when a presliding distance is set to zero. This applies equally to impedance synthesis, whereby a force is found from a displacement, or to admittance synthesis whereby a position is found from a force. By accessing pre-processed response data, the computational complexity is reduced, while the determination of the relative position of the point of contact within the currently active polygon makes it possible use a double interpolation process that ensures continuity of rendered forces and the passivity of the synthesized interaction although the original data is known only at a discrete locations.
