Patent CA-2268274-A1 (CA)
Title: Monoclonal antibodies specific for the psa-act complex
Inventor: LINTON HARRY JAY
IPC: C07K16/40
Filed: 1997-11-17
Abstract: Monoclonal antibodies have been developed which specifically bind the PSA-ACT complex without significant cross-reactivity with PSA, ACT or CG-ACT. The antibodies were generated using a unique immunogen comprising a PSA-ACT complex having bound to monoclonal antibodies against PSA and monoclonal antibodies against ACT. It is theorized that the antibodies against PSA and ACT block immunodominant sites on the PSA-ACT complex. The antibodies generated against the unique immunogen specifically bind the PSA-ACT complex, but have no significant cross-reactivity with either PSA or ACT. The monoclonal antibodies of the present invention can be used in immunoassays to specifically detect PSA-ACT in a sample.

Title: Intra-cavity and inter-cavity harmonics generation in high power lasers
Inventor: FU QIANG
IPC: H01S3/109
Filed: 1998-05-14
Abstract: Intra-cavity and/or inter-cavity sub-resonators (10, 20, 22, 50, 52, 32, 54) with dielectric coated mirrors (10, 50, 52, 54) have anti-reflection and high-reflection coatings to attain high efficiency third (32) and higher order harmonics generation of laser radiation. Main-resonators and sub-resonators enhance the fundamental and harmonic oscillation, respectively, which result is high conversion efficiency of third harmonics (32) and higher, such improved lasing efficiency may be implemented in higher power lasers for improved power performance to attain over 8 W of UV output power with a high repetition rate. The use of intra-cavity THG techniques provide high efficiency by using existing high intensities of the input fundamental frequencies available in the intra-cavity region of the laser to avoid damage to components of the laser, such as the laser crystal. The THG  utilizes a double-pass and/or multi-pass arrangement, which results in about a 60 % increase in output power compared to a single pass configuration. Also, blocking of UV energy generated in a return pass is performed to eliminate damage by the UV to components in the main cavity.

Title: Flexible bag with selectively-activatible support-engagement feature
Inventor: HAMILTON PETER WORTHINGTON
IPC: B65F1/14
Filed: 1998-05-06
Abstract: The present invention provides a flexible bag (10) comprising at least one sheet of flexible sheet material assembled to form a semi-enclosed container having an interior surface, an exterior surface, an opening having a peripheral edge (28), and a support-engagement feature (30) located on the exterior surface at least partially surrounding the peripheral edge. The support-engagement feature comprises a strip of material having a first side facing outwardly from the exterior surface and a second side facing inwardly toward the interior surface. The first side exhibits an adhesion peel force after activation by a user which is greater than an adhesion peel force exhibited prior to activation by a user. The support-engagement feature preferably at least partially, and more preferably fully, circumferentially surrounds the peripheral edge. The selectively-activatible support-engagement feature also preferably functions as a closure means (40) to secure the opening of the flexible bag in a substantially closed condition when the bag material is gathered about the opening, thus providing for ease of sealability without the need for additional closure features or separate elements. Additional closure means may be provided utilizing the selectively-activatible materials suitable for use as a support-engagement feature located on the inner surface of the peripheral edge of the bag. The support-engagement features of the present invention provide a flexible bag which is capable of reliably engaging a supporting device so it may be supported in an open condition for filling purposes. Such a feature also reduces the likelihood of trapped air and/or free space occurring when the bag is utilized with a rigid or semi-rigid durable container.
Patent CA-2291807-A1 (CA)
Inventor: ALEXANDER STEPHEN B
IPC: H04B10/08
Filed: 1998-05-29
Abstract: The present invention provides an optical monitoring system for a WDM optical communication system. In an exemplary embodiment, the monitoring system includes a wavelength selecting device which receives a WDM optical communication signal comprising plural optical channels and optical noise (e.g., ASE). The wavelength selecting device separately outputs optical signals corresponding to each of the optical channels and at least one optical noise sample taken at a wavelength which is not occupied by one of the optical channels. At least one optical power motor optically communicates with the wavelength selecting device for measuring the optical power of each of the optical channels and the optical noise sample. The optical power meter outputs an electrical signal indicating the strength of a measured optical channel or of the optical noise sample. A data analyzer, such as an microprocessor, receives the electrical signals output by the power meter and calculates the optical noise at the wavelengths of each of the N optical channels based upon the measured noise sample. Using the calculated optical noise values, the data analyzer determines the signal to noise ratio of each optical channel. Advantageously, the technique of the present invention uses a minimum of power measurements to accurately determine the signal-to-noise ratios of the optical channels.
