Abstract (en)
[origin: WO9942909A1] Method for modernizing a pendulum clock, by which the original character of the clock is maintained. For that purpose a control unit is added, together with a reference clock, a pneumatically driven cylinder and arresting means for arresting the pendulum. The pendulum clock is adjusted such that it runs slightly fast. Periodically, for example every hour, the pendulum is arrested up to the moment that the pendulum clock is in time with the reference clock. While the pendulum is arrested, the pendulum clock is wound up by the cylinder.
