Abstract

Abstract A weather vane is connected to a rotatable part by a one way in azimuth drive, such as a pawl and ratchet mechanism, and when the part has been moved angularly a specific number of degrees a signal is given and the time interval can be measured by a stop watch.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 75 words
The method of determining wind turbulence which comprises measuring the azimuth change by a one way in azimuth drive exemplified by a wind vane driving a pawl and ratchet mechanism including the rotational timing of one of said pawl and ratchet, noting a signal when the mechanism is at a selected point in azimuth change, noting another signal when the mechanism is at another point in azimuth change and timing the interval between the signals.
Claim 2
Independent Claim 75 words
The method of determining wind turbulence which comprises measuring the azimuth change by a one way in azimuth drive exemplified by a wind vane driving a pawl and ratchet mechanism including the rotational timing of one of said pawl and ratchet, noting a signal when the mechanism is at a selected point in azimuth change, noting another signal when the mechanism is at another point in azimuth change and timing the interval between the signals.
Claim 3
Dependent Claim 26 words
Method according to claim 1 in which more than one signal is given and noted in each 32 points (360*) in one direction of azimuth change.
