Title: The Innovative Contributions of Donald C True
Introduction
Donald C True is a notable inventor based in Brownsburg, California, recognized for his significant contributions to the field of explosives technology. With a total of six patents to his name, True has developed innovative solutions that enhance safety and efficiency in blasting operations.
Latest Patents
Among his latest patents is the "Delay Initiator for Blasting," which presents a novel initiator (blasting cap) for explosives. This initiator, which can be either electric or non-electric, features a principal tubular metal shell that contains a base charge, a delay charge, a priming charge, and an ignition means. The design includes a reduced diameter tubular metal shell that is housed within the principal shell, separated by a void space, resulting in improved resistance against shock initiation. Another significant patent is the "Electric Exploding Bridge Wire Initiators," which provides an assembly particularly suited for initiating a length of low energy shock wave conductor. This assembly comprises a hollow tube with an exploding bridge wire at one end, which directly initiates the shock wave conductor inserted into the opposite end. The entire assembly can be housed within a protective enclosure, allowing for snap-fit connection with a source of electrical energy. This initiator can be activated by relatively low voltage power supplies, making it significantly safer than conventional EBW initiators.
