Patent CA-2362097-A1 (CA)
Title: Chain saw adjuster
Inventor: TYNES RODNEY
IPC: B27B17/00
Filed: 2001-11-14
Abstract: An arrangement that provides a semi-automatic tension adjustment of an endless cutting chain on a guide bar of a chain saw as the links of the chain wear with use. A specially designed cam biases a tensioner pin to continuously force the guide bar away from the drive sprocket on the engine chassis to tension the chain. A knob on a clutch cover assembly attached to the engine chassis can be tightened to force two high friction surfaces together to lock the guide bar in a tensioned position, or loosed to release the guide bar to seek a proper tensioned position. An override lever on the face of the clutch cover assembly moves in a channel with peripheral nomenclature that indicates when the cutting chain should be replaced. The entire arrangement is self-contained and does not require any tools to function.

Patent CA-2381205-A1 (CA)
Title: Method for determining physiological effects of hemoglobin
Inventor: GOW ANDREW J
IPC: A61K35/18
Filed: 2000-08-02
Abstract: NO preferentially binds to the minor population of the hemoglobin's vacant hemes in a cooperative manner, nitrosylates hemoglobin thiols, or reacts with liberated superoxide in solution. The distribution of minor forms of hemoglobin can be tested and the results can be used to predict whether a composition of hemoglobin will scavenge, load, eliminate, or donate NO. Hemoglobin thus serves to regulate the chemistry of NO. SNO-hemoglobin transfers NO  equivalents to the red blood cell anion transport protein AE1, which serves to export NO from red blood cells. Regulation of AE1 function is the basis for methods of therapy to affect levels of NO or its biological equivalent.
