Patent CA-2578708-A1 (CA)
Inventor: HAIRSTON RONALD JAMES
IPC: G01F25/00
Filed: 2007-02-14
Abstract: Apparatus and associated systems, methods and computer program products relate to monitoring the performance of an operating gas meter by automatic and substantially continuous differential pressure (dP) measurement. Measured dP may be compared against a baseline dP characteristic to determine if the measured dP exceeds a threshold value above a baseline dP characteristic. If the threshold is exceeded, then the system may generate a signal to request repair or replacement of the meter. After installation, some embodiments collect dP data over time and/or over a range of flow rates to automatically learn a baseline dP characteristic under installation conditions. A system may switch from a default baseline dP characteristic to a learned baseline dP  characteristic. Some embodiments may further correct volume or flow rate signals for line pressure and/or temperature. Further embodiments provide a passive apparatus to protect a dP sensor against transients in line pressure and/or differential pressure.

Title: All-purpose natural plant fertilizer and soil enhancer, approved for growing organic plants and containing no animal by-products
Inventor: DIXON KAREN
IPC: C05G3/80
Filed: 2007-02-16
Abstract: Patent requested for a natural all-purpose fertilizer and soil enhancer called "Grow Organic" (In French: "Pousse Bio"). This fertilizer contains only plant and mineral sourced ingredients (no animal by-products) that are approved for growing certified organic plants. This fertilizer contains minerals, vitamins, proteins, enzymes, and sugars.

Title: Quad parabolic snowmobile ski
Inventor: PRYPUTNIEWICZ NICHOLAS
IPC: B62D55/07
Filed: 2007-10-04
Abstract: The quad parabolic snowmobile ski is an elongated body with a pair of symmetrically opposed ski parabolic cutting edges disposed longitudinally along the bottom and keel of the ski. The keel is attached to the bottom of the ski and has a central median ridge, i.e. a keel rail. A substantial portion of the keel rail protrudes below the bottom of the ski to form a central and longitudinal point of contact with the snow. The keel defines symmetrically opposed snow-funneling channels along the opposite sides of the central median ridge. Varying radii of curvature of the channels form parabolically-shaped channel outer sidewalls. Symmetrically opposed keel parabolic cutting edges are formed by contouring a keel body width to follow the contour of the parabolic shaped outer sidewalls at a constant cutting edge width.
