The first DC port is connectable to a DC source and the second DC port is connected to the third DC port. The AC port is connectable to an AC load. The load balancing energy storage element is connected to the second DC port for decoupling the DC to DC converter from the DC to AC converter by supplying energy to the third DC port when a voltage at the second DC port is tending to decrease and for storing energy received from the second DC port when a voltage at the third port is tending to increase.
Patent CA-2220826-A1 (CA)
Inventor: BLAIS FRANCOIS
IPC: G01C11/00
Filed: 1997-11-12
Abstract: A system and method for imaging reflective surfaces is disclosed wherein a diffused light source having a predetermined frequency range and in a predetermined pattern is directed toward the reflective surface. The light reflecting off the surface passes through a filter for filtering out ambient light and reaches a detector. The detector detects the light. Using triangulation with two points within the pattern, a microprocessor determines a distance to an image formed behind the reflective surface. The microprocessor also calculates a distance to the reflective surface in dependence upon the distance to the image and the locations of the diffused light source and of the detector. Alternatively, two detectors are used, requiring a point source of diffused light.

Inventor: DELZER GARY ALBERT
IPC: C07C41/06
Filed: 1997-05-20
Abstract: This invention provides an improved etherification process (20, 30) that reduces the amount of acidic ion-exchange resin catalyst that is deactivated by nitriles. This process uses a water phase to remove nitriles from a hydrocarbon phase followed by an alcohol phase to remove the nitriles from the water phase. A hydrogenation catalyst is used to convert the nitriles to amines so that they can be more easily removed from the alcohol phase. This invention also provides a process to remove nitriles (10, 60). This invention further provides an improved etherification process that reduces the amount of acidic ion-exchange resin catalyst that is deactivated by nitriles. These processes use a water phase to remove nitriles from a hydrocarbon phase followed by a stream, or fuel gas, phase to remove the nitriles from the water phase.

Title: A novel hypertension related calcium regulated gene (hcarg)
Inventor: HAMET PAVEL
IPC: G01N33/574
Filed: 1998-12-31
Abstract: This invention relates to a novel gene that shows tissue specific expression and increased expression in a low calcium concentration medium. Low renin hypertension is characterized by decreased levels of serum ionized calcium in the presence of increased levels of parathyroid hormone. It is hypothesized that hypertensive factor(s) are co-secreted with PTH in SHR, a model of low renin hypertension, the parathyroid hypertensive factor being one of them. This invention identifies the genes differentially expressed in humans and in rat models of low renin hypertension (SHR) and in normotensive rat models (WKY) that are induced by a low calcium levels in the parathyroid gland. A cDNA of a human gene and a cDNA of a rat gene expressed in parathyroid cells have been cloned and sequenced with no high score homology found in the gene banks. Their expression is higher in hypertensive models and their expression is enhanced by cell incubation in a low calcium concentration medium. In situ hybridization showed specific expression of the genes in adrenal medula and cortex, proximal tubules and parathyroid gland with very low levels in heart ventricles, kidney medulla and glomeruli and liver. These novel calcium regulated genes show tissue specific expression and increased expression in hypertension.
