Mobility Practices and Mobile Phone Data,those that have survived. The large number of Smith clocks, an alarm clock and a time switch (31 %) and Temco clocks (29 %) is noticeable. A number of clocks etc. (31 %) have Art Deco cases, but there are few clocks with other identifiable artistic styles. Relatively few clocks etc. (13 %) are self下船 发表于 2025-3-27 17:37:59
Implications for Urban and Mobility Policy, styles. About half the clocks, and the time switch, (47 %) are self starting. None of them has an outage indicator. About half the clocks, and the time switch, (47 %) do not have any form of tell tale to make it easy for a user to determine whether or not a clock, or the time switch, is running.

,From Empires to Nations, 1800–2015, satisfactory in service. The rotation speed of motors was a compromise. The most popular was 200 rpm, but this was not universal. Synchronous motors are not inherently self starting. Many clocks had manual start motors. Some had self starting motors, but reliability of self starting methods was som轻浮女 发表于 2025-3-28 00:47:42

Mapping Time, Space and the Bodyin the UK for use on a UK mains supply (200–250 V, 50 Hz). Domestic means a portable clock with an analogue display suitable for use in a domestic setting. This introductory chapter has a wide scope, including the historical background to synchronous clocks, the AC mains supply, and user experience.
