Don't you love auto translators? The following is what my translation gave me haha:
"[...]parts of the electrically operated device include an electromagnetic trigger attached to its handle, a battery, and a 'hell machine', i.e. a clock device that acts as a circuit breaker. The main part of the latter is an ordinary alarm clock: the brass pointer of the clock moves on the surface of the gramophone record (insulator), making the device work whenever it hits a copper wire contact passing through the record. A 'ghost machine gun' with several thousand cartridges in its metal belt thus fires short bursts at set intervals."
