isochrony

This makes the clock's rate sensitive to changes in the drive force, a problem called lack of isochronism.

For long this was recognized as a disturbing influence on the isochronism of the balance.

This problem, called lack of isochronism, plagued mechanical watches throughout their history.

The function layer only suffers minor changes to increase efficiency and support isochronism.

The superior performance of the deadbeat over the anchor is caused by its improved isochronism.

This problem is called lack of isochronism.

This property, called isochronism, is the reason pendulums are so useful for timekeeping.

Achieving isochronism was recognised as a serious problem throughout the 500 year history of spring-driven clocks.

Many keywind watch movements make use of a fusee, to improve isochronism.

Many parts were gradually improved to increase isochronism, and eventually the fusee became unnecessary in most timepieces.

Isochronism (the ability of the watch to keep time, regardless of the mainspring's level of tension).

Such springs were essential in modern watches with a detached lever escapement because they can be adjusted for isochronism.

It sounds an isochronism.

In addition to the improved accuracy due to isochronism, this allowed clocks to use longer pendulums, which had a slower 'beat'.

The most common method of achieving isochronism is through the use of the Breguet overcoil.

This property, called isochronism, is shared with ordinary pendulums and makes both types of pendulums useful for timekeeping.

This provides a more uniform amount of torque on the watch train, and thus results in more consistent balance amplitude and better isochronism.

Isochronism was occasionally improved through the use of a stopworks, a system designed to only allow the mainspring to operate within its center (most consistent) range.

In pendulum clocks, the wide pendulum swing angles of 80 -100 required by the verge cause an additional lack of isochronism due to circular error.

Note that under the small-angle approximation, the period is independent of the amplitude θ; this is the property of isochronism that Galileo discovered.

When the deadbeat was invented, clockmakers initially believed it had inferior isochronism to the anchor, because of the greater effect of changes in force on the pendulum's amplitude.

At the same time, he discovered a simple modification to his helical balance spring that let develop concentrically and, also, confer the property of isochronism on the oscillating balance.

Galileo discovered the key property that makes pendulums useful timekeepers: isochronism, which means that the period of swing of a pendulum is approximately the same for different sized swings.

In the deadbeat escapement, increased drive force does not change the period of the pendulum much, resulting in better isochronism and better timekeeping, but it does increase the pendulum's swing.

Techniques for adjusting the balance spring for isochronism and positional errors discovered by Abraham-Louis Breguet, M. Phillips, and L. Lossier were adopted.

Isochrony is the postulated rhythmic division of time into equal portions by a language.

Isochrony is one of the three aspects of prosody, the others being intonation and stress.

Vowels in unstressed syllables keep their full quality, giving rise to a syllable-timed rhythm (see Isochrony).
