Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
144 words
IN COMBINATION, A SONIC WAVE CONDUCTOR FOR DETERMINING THE VOLUME OF A FLUID IN A CONTAINER HAVING VARIABLE HORIZONTAL SECTIONAL AREAS DEFINED BY ITS WALLS, SAID CONDUCTOR HAVING FIN-LIKE MEANS FOR COUPLING ELASTIC WAVE ENERGY BETWEEN SAID CONDUCTOR AND A SURROUNDING FLUID MEDIUM, SAID FIN-LIKE MEANS EXTENDING RADIALLY FROM AN ELONGATED CENTRAL AXIS, SUPPORT MEANS DISPOSING SAID CONDUCTOR IN SAID CONTAINER WITH SAID AXIS NORMAL TO AND NORMALLY BREAKING THE SURFACE OF SAID FLUID, SAID FIN-LIKE MEANS VARYING IN DIMENSION IN ACCORDANCE WITH THE VARIATIONS IN THE SECTIONAL AREAS DEFINED BY SAID WALLS WHEREBY THE LONGITUDINAL VELOCITY OF WAVES IN SAID CONDUCTOR ALONG SAID AXIS IS VARIED IN ACCORDANCE WITH SUCH VARIATIONS IN THE SECTIONAL AREAS, AND MEANS TO VIBRATE AN END OF SAID CONDUCTOR PERIODICALLY IN A DIRECTION TO CAUSE PERIODIC DISPLACEMENT OF SAID FIN-LIKE MEANS HAVING SUBSTANTIAL COMPONENTS NORMAL TO ITS SURFACE.
