The fuse can be protected during the operation by a boss above it, and which is removed on completion. A high capacity per unit of vol. is achieved.
Patent DE-2934039-A1 (DE)
Title: Protected remote control of radio station channel - requires instructions to be validated by exchange and acknowledged by remote station
Inventor: DRIESNER JOERN MICHAEL DIPL IN
IPC: H04B17/00
Filed: 1979-08-23
Abstract: The frequency channel of an unattended radio station is remotely selected from a part-time attended exchange by transmitting a 5-tone code signal over a line. When the channel selector is changed at the central, an alarm is sounded and the signal is not sent until validated by operating a key. The remote station checks the signal for validity, executes the channel change, and acknowledges the signal by returning it to the exchange over a different line. The exchange checks the acknowledgement against the original and lights an indicator lamp is correct. If the mains supply is restored at the remote station after a failure, it transmits a 1-tone request. The exchange responds by retransmitting the last channel change signal. The system protects against interference by unauthorised persons or errors in transmission.
