Patent CA-2206785-A1 (CA)
Title: Composition for providing in-situ stabilized compositions
Inventor: HESP SIMON
IPC: C08L95/00
Filed: 1992-09-30
Abstract: A composition is provided for forming a stable dispersion of insoluble particulate materials in a continuous non-aqueous phase by employing a pro-steric stabilizer to render the dispersion stable and resistant to phase separation.  The pro-steric stabilizer permits in-situ stabilization involving the formation of chemical bonds between the stabilizer components and to dispersed phases to form a network surrounding the particles which is compatible with the continuous phase. The invention has particular application for the formation of stabilized polyolefin-modified bitumen compositions for paving and other applications.
Patent CA-2207256-A1 (CA)
Title: Seal for a universal joint trunnion
Inventor: REYNOLDS JAMES T
IPC: F16D3/41
Filed: 1997-06-06
Abstract: An elastomeric seal assembly for use with a bearing cup mounted on a trunnion of a universal joint cross member includes an elastomeric seal attached to a metallic support ring. The metallic rings are pressed into the open ends of the bearing cups and are retained therein by friction. The elastomeric seals each include first, second and third radially inwardly extending sealing lips. When the bearing cups and sealing assemblies are mounted about the trunnions the annular lubricant sealing lip engages the frustoconical sealing surface of the trunnion. The annular lubricant sealing lip is slanted towards the closed end of the cup to prevent lubricant from flowing past the seal and out of the roller bearing region. The second sealing lip engages the cylindrical sealing surface of the trunnion and is slanted towards the open end of the cup to resist the entry of abrasive contaminants into the roller bearing region. A third sealing lip engages the cylindrical sealing surface of the trunnion and is slanted in the same direction as the first contaminant sealing lip. The second contaminant sealing lip resists the movement of contaminants towards the first contaminant sealing lip thereby prolonging the life of the seal and universal joint.

IPC: G01N33/74
Filed: 1997-09-23
Abstract: A diagnostic protocol and kit for evaluating pituitary growth hormone (GH) secretory capability as a means to identify the etiology of GH deficiency in children and adults is disclosed.  The inventive protocol includes measuring GH secretion, provoked by independent, sequential administration of the xenobiotic GH releasing hexapeptide (GHRP-6) or any of its peptidyl or non-peptidyl synthetic analogues (GHRX) that release GH by the same cellular mechanism as GHRP-6 followed by the naturally occurring GH releasing hormone or its analogues (GHRH) to children and adults afflicted with disorders related to GH deficiency.   After evaluating the effects of independent, sequential administration of the GH secretagogues upon changes in blood GH concentrations, the effect of the co-administered GH secretagogues on blood GH concentrations in the child or adult subject is then measured.

Title: Clearance measurement system
Inventor: ROBERGE JAMES K
IPC: G01B7/14
Filed: 1996-04-25
Abstract: Disclosed are a system and method for the accurately calibrated non-contact capacitive measurement of small distances between relatively movable elements.  The system and method are particularly well-suited for use in environments of high temperature, pressure, and vibration, including in jet engines to measure the gap between fan blades and the engine wall. A sensor disposed in a housing wall receives constant bias voltage and forms a sensing capacitor with the moving targets, which move past the sensor. A blocking capacitor allows a signal generated at the sensor to pass to a constant gain amplifier, which amplifies the signal and passes the amplified signal to a computer for calculating the small distances between the relatively movable elements using the bias, voltage, the gain, and the maxima and/or minima of the amplified output signal.

Title: Pigments durables pour plastiques
Inventor: GREEN KELLY A
IPC: C09C1/36
Filed: 1997-03-20
Abstract: La présente invention concerne un perfectionnement de pigments non organiques enduits d'alumines. De tels pigments, qui comportent une première couche en alumine à boehmite, une deuxième couche en alumine amorphe, et une troisième couche en alumine à boehmite, font preuve d'une bonne durabilité, d'une bonne dispersibilité et de propriétés optiques dans des compositions de plastiques. L'invention concerne également un procédé consistant d'abord à broyer une boue aqueuse d'un pigment non organique contenant de l'alumine de façon à obtenir une distribution spécifique des tailles particulaires, puis à précipiter dans les limites d'une première plage de pH sur la matière pigmentaire une première couche en alumine à boehmite. Le procédé consiste ensuite à ajouter à la boue aqueuse une deuxième charge destinée à former, dans les limites d'une deuxième plage de pH, la couche en alumine venant constituer, sur la première couche d'alumine à boehmite, une deuxième couche en alumine amorphe, à la suite de quoi on corrige le pH de la boue pour qu'il se situe dans les limites d'une troisième plage de pH. On obtient ainsi une troisième couche en alumine à boehmite recouvrant la deuxième couche en alumine amorphe.

Abstract: A hinge and closure mechanism with an integral door stop which, together with the closure unit of the mechanism, stops a refrigerator door from opening beyond a preselected position is described. In one embodiment, the mechanism includes a hinge unit, a closure unit, and door stop. The hinge unit includes a cabinet hinge plate and a door hinge plate. The cabinet hinge plate is mounted to the base of the cabinet, and the door hinge plate is mounted to a refrigerator door. A connector pin and a pivot pin extend through respective openings in the door hinge plate, and door hinge plate is coupled to the cabinethinge plate by the pivot pin. The closure unit includes a pivot plate coupled tothe door hinge plate by the connector pin. The closure unit also includes a compression spring and a link. The link couples the spring to the pivot plate. A pin stop slot is located in the pivot plate, and the dimensions of the slot are selected to correspond to the position at which it is desired to stop the refrigerator door. A pin stop extends through the pin stop slot and is engaged to the cabinet hinge plate. More particularly, the pin stop includes a flange which prevents the pin stop from extending completely through the pin stop slot.The pin stop also includes a bushing having a first portion and a second portion. The bushing first portion extends through slot for minimizing friction between the slot and the pin stop, and the bushing second portion has an end in contact with the cabinet hinge plate. The pin stop further includes a threaded end sizedto be inserted into the pin stop opening in the cabinet hinge plate for being threadedly engaged to cabinet hinge plate. As the refrigerator door is opened, the pivot plate rotates with the door. When the pivot plate rotates to a point at which the pin stop is located at the far end of the slot, the pin stop abuts against the pivot plate and prevents further rotation of the door.
