Abstract

Objects are detonated by placing charges adjacent respective ones of the objects and connecting the charges to a time fuse by means of respective explosive cords for detonating all of the charges simultaneously when the time fuse fires. The time fuse can be set by fitting a clock to the time fuse. The clock has separate timer mechanisms which can be wound-up simultaneously and which prevent the clock from being fitted to the time fuse if the timer mechanisms have run down asynchronously. An adapter can be attached to the time fuse for releasing a safety of the time fuse upon receiving a remote signal such as an encoded radio signal.
