Patent CA-2547136-A1 (CA)
Title: Novel strain of pseudomonas aeruginosa and related therapeutic components
Inventor: BURROWS LORI L
IPC: C12N9/10
Filed: 2006-05-09
Abstract: Pseudomonas aeruginosa is a Gram negative bacterium that uses polar type IV pili to adhere to and rapidly colonize surfaces. Within the P. aeruginosa species, there are five distinct alleles of the structural subunit, PilA, varying in amino acid sequence, association with specific accessory genes and presence of post-translational modifications. Group IV pilins from strain Pa5196 continued to be modified in a lipopolysaccharide mutant of Pa5196, demonstrating that, unlike group I strains, the pilins of group IV are not modified with O-antigen units. Using a combination of mass spectrometry and NMR spectroscopy, the pilin glycan was determined to be a linear oligosaccharide of five to eight alpha-1, 5-linked D-arabinofuranose (D-Araf) residues, covalently O-linked to the pilin via Thr.  This sugar is rare in prokaryotes, occurring mainly in the unusual cell walls of mycobacteria, including the important human pathogens Mycobacterium tuberculosis, M. leprae and M. avium-intracellulare complex, where alpha-1,5-linked D-Araf chains link mycolic acids to peptidoglycan. Due in part to the technical challenges of working with slow-growing, pathogenic mycobacteria and extracting complex cell wall components for analysis, biosynthesis of D-Araf containing--polymers is poorly defined. We propose that P. aeruginosa Pa5196, a rapid-growing and genetically tractable strain of low virulence that expresses copious glycosylated pili on its surface, represents an excellent model system for elucidation of the pathways for biosynthesis of D-Araf and its polymerization into mycobacterial-like .alpha.1,5 linked oligomers. Identification of the enzymes catalyzing these steps could provide novel targets for development of new anti-mycobacterial drugs.

Title: Heat pump system having a defrost mechanism for low ambient air temperature operation
Inventor: LI GANG
IPC: F25B47/02
Filed: 2006-09-27
Abstract: A heat pump system includes a hot gas bypass defrost mechanism which enables normal heat pump operation at low ambient air temperatures, and may be used for heating swimming pools. The bypass defrost mechanism is activated by sensing a drop in compressor suction line pressure, which occurs at low ambient temperatures when frost forms on an evaporator in the heat pump, which disrupts normal heat pump operation. The defrost mechanism includes a circuit that redirects a portion of hot refrigerant discharged by a compressor directly to the evaporator, thereby bypassing other heat pump components and defrosting the evaporator.

Patent CA-2580232-A1 (CA)
Inventor: YANG JIANMING
IPC: F22B37/76
Filed: 2007-02-26
Abstract: The Sail Style Fluid Flow Switch uses sail assembly to sense fluid flow. There is no mechanical linkage between sail assembly and contact assembly. They are separated by an enclosure. There is no moving part through the wall of the enclosure, no wear happens against the enclosure, so less leaking will happen. The flow sensing part is a sail, the sail rotates around the center of sail arm with the sail arm, the rotation won't be restricted by the ratio of length of the sail arm to the diameter of conduit. Magnet and armature are used to transfer the status of sail assembly to the status of contact assembly. When there is fluid flow through the conduit, the sail driven by the fluid flow rotates with the sail arm and drives the magnet to activated position, where it can attract the armature of contact assembly toward the magnet, so NO (normally opened) contact closes and NC ( normally closed ) contact open. After the fluid flow stops, a spring drives the sail assembly to the normally non-activated position, and the contact assembly returns to its non-activated status.
