Open the CIPO recordAbstract From the Canadian patent
A method and four devices for measuring the change in mass of a sample subjected to selected temperatures and fluid variables is disclosed The test sample is subjected to centrifugal force to amplify the "apparent mass" of the sample by rotating the sample about a first axis of rotation. Any change in the mass of the test sample is then amplified by the centrifugal force and measured by the displacement of the sample about a second axis of rotation. The above method and four separate devices are disclosed. The first device balances the mass of the test sample against a known reference sample. The second device generates a counterrotational force about the second axis to bring the sample to …
