Patent CA-2302986-A1 (CA)
Inventor: DU WEICHONG
IPC: G02F1/19
Filed: 2000-03-16
Abstract: It is known that the deleterious effects of chromatic dispersion in an optical communications system can be overcome by reflecting the optical signal from a chirped Bragg grating. In this invention, the dispersive characteristics of the Bragg grating may be altered by inducing a temperature gradient along the axis of the grating, where this gradient arises due to the absorption of photons from a pump source, and the subsequent emission of phonons. The central wavelength of the Bragg grating may be altered by stretching or compressing the grating, or by varying the ambient temperature surrounding the grating. The device has additional applications in compensation of polarization-mode dispersion, pulse shaping, and pre-chirping of directly modulated lasers.

Patent CA-2320027-A1 (CA)
Inventor: KAISER GARRY R
IPC: E21B33/06
Filed: 2000-09-21
Abstract: A pair of ram blocks are provided such that when they are actuated hydraulically to move together, they present an opening which has a series of gripping members downwardly biased. Removal of tubulars or tools from the well bore works against the bias to retract the grippers so that removal can be accomplished. However, if there is an accidental release, the bias pushes the grippers toward the tubular or tool to grip it to prevent loss into the well bore. The ram blocks can be retracted for run-in to the well bore.

Title: Paramyxovirus vectors used for transfer of foreign genes
Inventor: NAGAI YOSHIYUKI
IPC: C12N15/86
Filed: 2000-10-27
Abstract: A paramyxovirus vector capable of Extransfectingforeign genes and having a replication capacity, is provided. A Sendai virus vector comprising a foreign gene can be constructed by inserting a foreign gene between the viral genes of the Sendai virus genome. These Sendai viruses have a replication capacity and express the foreign gene in transfected cells. The expression level of the foreign gene is higher towards the 3' end of negative strand RNA, and especially, a high level of expression is obtained when the foreign gene is inserted before the NP gene, and between P gene and M gene. Conversely, the expression decreases towards 5' end of negative strand RNA, and especially, a relatively low level of expression is obtained when the when the foreign gene is inserted between HN gene and L gene, and between F gene and HN gene. Thus, the vector of the invention enables the regulation of the expression level of a foreign gene.      The vector is useful for gene therapy due to its safety, high gene transfer efficiency, and capacity to express a foreign gene at a high level.
