Title: Compositions et procedes pour ameliorer la sante dentaire globale et l'apparence des dents
Inventor: BAIG ARIF ALI
IPC: A61K8/55
Filed: 2008-06-25
Abstract: L'invention concerne des compositions de soin oral comprenant des composés organophosphatés tensioactifs sélectionnés et des procédés d'utilisation pour assurer une protection des dents contre l'érosion provoquée par l'action de substances chimiques, comme les abrasifs et les acides durs. Les composés organophosphatés tensioactifs s'intègrent aux dents, les groupes phosphate liant le calcium dans les dents et empêchant ainsi la perte de calcium par dissolution lorsqu'elles entrent en contact avec des acides. Le composé organophosphaté peut également déposer un revêtement de surface protecteur qui empêche le contact entre les dents et des substances susceptibles de les éroder. Les composés organophosphatés sélectionnés contiennent un ou plusieurs groupes phosphate et sont combinés dans la composition de soin oral avec un ou plusieurs agents à ion fluorure, un agent antimicrobien choisi de préférence parmi les composés ammonium quaternaire et les sels de métaux polyvalents, un agent antitartre et un tensioactif supplémentaire, pour apporter des avantages notamment des avantages anti-érosion, anticaries, antiplaque et anticoloration supérieurs, comme le démontrent l'absorption améliorée du fluor, la reminéralisation, la résistance à la déminéralisation par les acides et des activités antimicrobiennes, qui se traduisent par une amélioration de la santé dentaire globale, de l'intégrité structurelle et de l'apparence.

Patent CA-2730004-A1 (CA)
Inventor: HALL DAVID B
IPC: G01H9/00
Filed: 2009-07-09
Abstract: Two optical wavelengths are used to interrogate a fiber optic Fabry-Perot sensor (1-4) having a moveable diaphragm (34) that changes the width of a gap (36) between two reflective surfaces (38, 40). By picking the right operating point for the gap (36), the power output for one wavelength increases as the gap width changes and the power for the other wavelength decreases. A ratio of the difference of the two powers over the sum of the two powers is formed to generate a detected signal independent of power and phase fluctuations in a fiber (22) between signal sources (46, 48) and sensor (1-4) and between sensor ( 1-4) and detector (73). This ratio, which is called the visibility, has a response proportional to the pressure of acoustic disturbances that move the diaphragm (34). The push-pull sensor (1-4) can be used with both TDM  and CW fan-out array architectures (45, 47).

Abstract: A process for fracturing a lined well uses a packer assembly in a liner string that provides a cement-free segment and interface with the formation. The device has multiple packers with inflatable elements that are run as an integral assembly. After the liner assembly is positioned, cement is circulated into the assembly and wiped from the interior of the liner string into the annulus. Pressure within the liner string is elevated to initiate time delays for the radial inflation of the packer elements. The inflation radially and axially displaces the cement surrounding the elements before the cement sets. Each packer is subsequently opened to expose the frac ports in the packer directly to the formation for frac operations.
