Filed: 2000-06-20
Abstract: L'invention concerne un procédé d'extraction de protéines membranaires entières Gram négatif, à partir de bactéries ou cellules hôtes bactériennes contenant un vecteur de recombinaison, ce procédé consistant en une diafiltration différenciée à écoulement tangentiel, au moyen d'un détergent. Ce procédé comporte plusieurs avantages sur des autres procédés. D'abord, il combine les processus de clarification et d'extraction en une seule opération, le produit étant extrait des cellules et séparé des débris de celles-ci au moyen d'un seul processus de diafiltration en continu. Ensuite, les protéines membranaires sont extraites à l'état semi-purifié, ce qui simplifie les étapes de traitement en aval. Troisièmement, ce procédé est très facilement modifiable, étant donné que la seule règle à respecter est l'augmentation de la surface des membranes proportionnellement à la quantité de cellules.

Abstract: A helicopter wear line cover for protecting and separating a load bearing cable used for lifting a load suspended from a helicopter from a non-load bearing cable used for controlling the release of the load which includes a pair of elongated flat side members connected together longitudinally along two lines of attachment to form a first tube between the side members, a first attachment member attached to one of the side members adjacent a first edge and a second attachment member attached to the other of the side members remote from the first edge. When the first and second attachment members are attached together, the side members form a second tube parallel with the first tube and separated from the tube by one of the side members and the diameters of the first and second tubes are large enough to enable free longitudinal movement of the cables within the first and second tubes when the first and second attachment members are attached together.

Title: Semiconductor laser with disordered and non-disordered quantum well regions
Inventor: SARGENT EDWARD H
IPC: H01S5/34
Filed: 2002-02-21
Abstract: In a semiconductor laser, non-disordered quantum well active region functions as a lasing region. Surrounding the non-disordered quantum well active region is a disordered quantum well active region which prevents diffusion of injected carriers from the non-disordered quantum well active region or provides a lateral heterobarrier. The disordered quantum well active region is formed by rapid thermal annealing in which defects from one or two InP defect layers diffuse into the parts of the quantum well active region to be disordered.
Patent CA-2372906-A1 (CA)
Title: Low dispersion interleaver
Inventor: PICARD MARIE JOSEE
IPC: G02B6/34
Filed: 2002-02-22
Abstract: The present invention relates to an interferometer useful in the interleaving and de-interleaving of optical wavelength channels. Typically the invention comprises a beamsplitter and two resonators, e.g. GT etalons or ring resonators. The beamsplitter splits an input beam of light into a first sub-beam directed to follow a first path and a second sub-beam directed to follow a second path. The first resonator has a first effective cavity length and receives the first sub-beam. The second resonator has a second effective cavity length and receives the second sub-beam. The first path and the second path have an effective optical path difference approximately equal to one-half the first effective cavity length. In one embodiment, the front plates of the GT etalons each have a different reflectivity, and are selected to provide a desired spectral response. In another embodiment, the two resonators are slightly de-phased from one another such that the positive dispersion slope of the first resonator is aligned with the negative dispersion slope of the second resonator. Polarization-based versions of the invention are disclosed, in which a single resonator receives both sub-beams, which are orthogonally polarized. Single etalon versions of the invention are also possible, in which a beam is separated into sub-beams (i.e. reflected and transmitted beams) within a non-linear interferometer, and then re-combined outside the interferometer with the appropriate effective optical path length delay therebetween.

Title: Colloidal photonic crystals
Inventor: RARITY JOHN GILROY
IPC: C30B5/00
Filed: 2000-09-05
Abstract: A method of growing robust large area colloidal photonic crystals and devices produced thereby. A suspension of monosized colloidal spheres (1) is subjected to a composite shear (6) by applying a sequential set of shearing forces. The crystalline layers within the colloid experience shearing forces with components in both x and y directions, forcing the colloid into a single face-centred-cubic structure in preference to a twinned face-centred-cubic structure. The method may also comprise the use of a dispersion medium which is capable of undergoing a controllable phase change from a liquid phase to a solid phase. The crystal may be fixed into a single face-centred cubic structure.

Title: High power semiconductor laser diode
Inventor: SCHMIDT BERTHOLD
IPC: H01S5/343
Filed: 2002-05-09
Abstract: Semiconductor laser diodes, particularly high power AIGaAs-based ridge-waveguide laser diodes, are often used in opto-electronics as so-called pump laser diodes for fiber amplifiers in optical communication lines. To provide the desired high power output and stability of such a laser diode and avoid degra-dation during use, the present invention concerns an improved design of such a device, the improvement in particular significantly minimizing or avoiding (front) end section degradation of such a laser diode and significantly in-creasing long-term stability compared to prior art designs. This is achieved by establishing one or two "unpumped end sections" of the laser diode. One preferred way of providing such an unpumped end section at one of the laser facets (10, 12) is to insert an isolation layer (11, 13) of predetermined posi-tion, size, and shape between the laser diode's semiconductor material and the usually existing metallization (6).

Title: Method for the direct esterification of sorbitol with fatty acids
Inventor: JOHNSON JOE W
IPC: C07C69/33
Filed: 2000-10-13
Abstract: Mixtures of sorbitol fatty acid esters useful as low calorie fat substitutes are prepared through a direct esterification process. The process entails the direct esterification of sorbitol with free fatty acids, optionally in the presence of an esterification catalyst. The resulting sorbitol esters have an average degree of hydroxyl substitution ranging from about 3 to about 5.5.  This partial esterification leads to a mixture of esters capable of serving as low calorie fat substitutes without undesirable physiological side effects or the need for additives. Furthermore, the direct esterification process proceeds without the need for large amounts of organic solvents of bleaching agents.

Title: Synchronization of plural databases in a database replication system
Inventor: STRICKLER GARY E
IPC: G06F17/30
Filed: 2002-08-09
Abstract: In a database synchronization process, a block of data is read from a source database at the first node. A marker is assigned to the block of data, and the marker is then written to an audit trail at the first node. The marker is sent from the audit trail to a second node having a target database. The block of data is sent from the first node to the second node without passing the block of data through the audit trail. At the second node, the block of data is stored in the target database upon receipt at the second node of the block of data and the marker assigned to the block of data. This process is repeated for additional blocks of data in the source database, wherein a marker is assigned to each subsequent block of data. In this manner, some or all of the source database may be replicated to the target database without having to store or pass any data in the source database in or through the audit trail at the first node.
