Patent CA-2212276-A1 (CA)
Title: Composite constructions with oriented microstructure
Inventor: SUE J ALBERT
IPC: C22C49/00
Filed: 1997-08-01
Abstract: In one embodiment, composite constructions of the invention are in the form of a plurality of coated fibers bundled together to produce a fibrous composite construction in the form of a rod.  Each fiber has a core formed from a hard phase material, that is surrounded by a shell formed from a binder phase material.  In another embodiment of the invention, monolithic sheets of the hard phase material and the binder phase material are stacked and arranged to produce a swirled composite in the form of a rod.  In still another embodiment of the invention, sheets formed from coated fibers are arranged to produce a swirled composite.  Inserts for use in such drilling applications as roller cone rock bits and percussion hammer bits, and shear cutters for use in such drilling applications as drag bits, that are manufactured using conventional methods from these composite constructions exhibit increased fracture toughness due to the continuous binder phase around the hard phase of the composites.  These binder phases increase the overall fracture toughness of the composite by blunting or deflecting the tip of a propagating crack.
Patent CA-2213063-A1 (CA)
Inventor: ZACOUTO FRED
IPC: A61F2/48
Filed: 1997-07-22
Abstract: Ce dispositif comprend un implant squelettique pourvu d'une géométrie et d'une viscosité réglable de façon non invasive. Cet implant comprend au moins deux parties (503, 504) ces deux parties possédant entre elles un coefficient de viscosité qui est réglable post-opératoirement au moyen d'un élément (509) agissant de façon transcutané. Une résistance élastique peut être ajoutée, résistance qui est également variable dans des conditions similaires non-invasives. Ces commandes post-opératoires permettent également un réglage d'une des dimension de l'implant osseux tel que la longueur de son axe longitudinal (315). Les aspects mécaniques du dispositif sont basés sur l'hydraulique d'une huile de silicone qui peut se référer aux pressions de position du corps spontané ou provoqué lorsque la télécommande est activée (fig. 17a-17d). Dans le cas où une fuite interne se produirait au cours de la durée de vie de la prothèse, une compensation automatique est prévue pour corriger ceci en prélevant de l'énergie des mouvements naturels du patient. Ce dispositif trouve des applications dans la chirurgie corrective de la colonne vertébrale et de sa mobilité aussi bien qu'en ce qui concerne d'autres os ou articulations telle que l'articulation coxo-fémorale (fig. 32).

Inventor: WAKARCHUK DAVID A
IPC: A01N25/18
Filed: 1997-11-07
Abstract: Composite  polymer dispensers  capable  of  controlled release of semiochemicals have been developed.  The dispensers make use of a solid elastomer matrix reservoir which is at  least partially surrounded by a permeable release rate controlling polymer membrane.   The matrix materials are polyurethanes compatible with many types of semiochemicals and additives.  The release rates of semiochemicals from the dispensers can be varied over a wide range by manipulation of the reservoir conditions and by selection of the type of permeable polymer membrane surrounding the device.  The dispensers can have a variety of forms and can be produced by a simple process.  The semiochemical devices produced by this method are useful for managing insect  and other pests  through attraction to traps, for population monitoring or for mass trapping.  The devices may also be used to dispense  anti-aggregation pheromones or repellents in addition to use for mating confusion or disruption.

Abstract: A vehicle safety arrangement comprising a seat back support (4a) adapted to be attached to the back of a vehicle seat (50) and a side impact protective air bag module comprising an inflator (1) and a folded inflatable air bag (8). The seat back support (4a) is formed with integrally moulded or extruded flanges forming a housing for the inflator (1) and the air bag (8), and with a gas channel (16) linking the inflator (1) with the air bag (8). The arrangement can be placed outside the seat structure and will not conflict with occupant comfort. Furthermore since it is independent of the seat structure it can be manufactured separately. The arrangement also comprises fewer component parts with attendant cost and weight savings and making it easier to manufacture.  The seat back support (4a) is a plastic module which can be snapped or bolted onto the back of a front seat (50) and is generally used to prevent injury to rear passengers such as from submarining.
