Abstract
Modular components including donor units (20), relay units (30), and detonator units (50) create a variety of blasting systems. A donor unit (20) is formed from a signal transmission tube (22) having donor mini-caps (24) attached to each end thereof. A relay unit (30) is a device having a receptacle (32) at one end to receive a donor mini-cap in operative association and engaging means (34) to operatively engage a point along another donor unit such that the detonator contained within the relay unit (30) will initiate the transmission lines passing through the donor unit. A detonator unit (50) is provided for the initiation of explosives such as boosters and primers and comprises a shell for receiving explosives and a receptacle at one end suitable for receiving a donor mini-cap (24) at the other end. Relay units (30) allow for the simultaneous initiation of several donor units. Each donor unit can be attached to either additional relay units or to detonator units (50). Detonators can instantaneously explode or be fitted with delay elements. Thus, complex detonation patterns can be constructed with relatively few, easily assembled modular components.
