Patent CA-2172284-A1 (CA)
Inventor: MAMMONE RICHARD J
IPC: A61B3/10
Filed: 1995-06-07
Abstract: Quantitative measurement of corneal surface topography is obtained by processing a two-dimensional image of the surface (6) which reflects a quasi-periodic illuminated pattern, such as a series of concentric rings (13), from a Placido disk source. The local spatial phases exhibited by the image of the illuminated pattern when reflected from the corneal surface and when reflected from standard specular surfaces are obtained by processing the images (42). The distances at which predetermined local spatial phases are observed in the image from the cornea are compared (42) with the distances at which these same phases are observed in the images of the standard surfaces. The distances are also compared (42) with certain corresponding distances on the source and converted to reveal the dioptric powers of refraction of the corneal surface without the need for parametric interpolation.  During processing, any mislocation of the apex of the corneal surface along the optical axis is compensated for.

IPC: C12N9/88
Filed: 1994-11-17
Abstract: L'invention concerne des compositions pharmaceutiques destinées à apporter une dose efficace d'une héparinase sur un site désiré, et qui sont basées sur la découverte que l'héparinase seule peut inhiber l'angiogenèse. Le dosage efficace dépend non seulement de l'héparinase mais également de la méthode et des moyens d'apport, qui peuvent être par voie localisée ou générale. Par exemple, dans certaines applications, comme dans le traitement du psoriasis ou de la rétinopathie diabétique, on administre l'inhibiteur au moyen d'un exipient ophtalmique topique. Dans d'autres applications, comme dans le traitement de tumeurs solides, on administre l'inhibiteur au moyen d'un implant polymère biodégradable.

Title: Apparatus and method for deployment of radially expandable stents by a mechanical linkage
Inventor: MARIN MICHAEL L
IPC: A61F2/06
Filed: 1995-02-08
Abstract: The invention provides a method and apparatus for intraluminal delivery and deployment of an expandable prosthesis at a site within a body lumen. The apparatus for intraluminal delivery and deployment includes a support for supporting the expandable prosthesis while being delivered to the site within the body lumen, and a radially displaceable mechanical linkage connected to the support for radially displacing the support. The linkage is adapted to deploy the expandable prosthesis when it is displace radially outward. The linkage permits continuous fluid flow within the body lumen while the expandable prosthesis is being deployed. The present invention can also be used without stents for expanding a body lumen. The present method comprises steps of transmitting a radially, outwardly directed displacement force to the support from a control mechanism, the support being displaced radially outwardly to an expanded stance such that the prosthesis contacts the body passageway, and transmitting a radially inwardly directed displacement force to the support from a control mechanism, the support being displaced radially inwardly to a recoiled stance less than the diameter of the body passageway while leaving the prosthesis in contact with the body passageway. Fluid flow is permitted throughout the delivery and deployment process.
Patent CA-2185169-A1 (CA)
Title: Retrievable well packer
Inventor: HENDRICKSON JAMES D
IPC: E21B33/12
Filed: 1993-05-12
Abstract: A retrievable packer for service at high temperatures and pressures has sealing provided by a seal element prop surface (56) of larger diameter than the seal element support surface (48) of a body mandrel (34).  At least one element (30A) of a seal assembly (30) is supported on the prop surface and is subjected to a radial squeeze in the set configuration, even though a lowermost seal element (30C) may be subject to longitudinal separation.  The split level support arrangement provides an annular pocket (62) into which the elements can be retracted upon release of the packer, thereby providing clearance for retrieval.  In releasing the packer, a retainer collar (68) is shifted away from a metal backup shoe (64), thereby providing an annular pocket into which the shoe is deflected, so that it does not obstruct the drift clearance during retrieval.  The seal element assembly is preloaded by a cover sleeve (50) which releases when a predetermined compression has been achieved.  The controlled preloading of the seal elements assists movement of the elements to the larger diameter prop surface, and the seal elements are forced to expand into the annulus uniformly to prevent the formation of uneven extrusion gaps.

Title: Partially sprung drive, in particular for electric traction vehicles
Inventor: SKUMAWITZ ERWIN
IPC: B61C9/50
Filed: 1996-01-24
Abstract: A partially spring-loaded drive, particularly for electrically-powered rail vehicles, having a gear which, including an encapsulating gear housing, is seated on the wheel axle, and a pinion that is seated in the gear housing. The coupled motor is fixedly secured to the truck, and the resilient, elastic fastening of the gear housing to the truck is effected by way of at least two elastic spring elements that are mounted nearly vertically and diametrically opposite the pinion shaft, and whose lines of influence extend through the center of the pinion shaft. To avoid the disadvantages associated with truck-side pendulum suspensions of the drive housing outside of the pinion shaft, and provide a solution to the fastening of the gear housing to the truck, with which a stabilizing effect can be achieved for protecting the bearings in addition to an economical minimization of deformation losses of the coupling, a defined radial prestressing of the gear housing with respect to the wheel set is established using the transverse elasticity of the spring elements. The radial prestressing can usefully be established above and below the gear housing by way of an arrangement of rubber thrust springs having support surfaces.
