I don't know about how they do it, but Frank King has written about how he keeps the University clock in Cambridge reasonably in sync: http://www.scy.org.uk/chimes.htm The Big Ben chimes were copied from Cambridge. There's another clock in Trinity College which has a similar mechanism to the Big Ben clock, and a much more sophisticated monitoring system than the University clock - http://trin-hosts.trin.cam.ac.uk/clock/main.php The second page of this has pictures of the ajustment weights and how they are placed on the pendulum. http://trin-hosts.trin.cam.ac.uk/clock/img/TCSS_Newton_2010.pdf The setups for adding coins to the pendulums of Big Ben and the University clock are not quite as beautifully engineered as this!

Moderate or rough, becoming very rough later in west. Wintry showers then rain. Good, occasionally poor. _______________________________________________ LEAPSECS mailing list [email protected] https://pairlist6.pair.net/mailman/listinfo/leapsecs
