Abstract: An explosive composition is provided that is comprised of a Heavy ANFO and grain hulls. In one embodiment, the grain hulls are comprised of rice hulls. The grain hulls serve both as an inert bulking additive that reduces the density of the composition and as a sensitizer that reduces the energy needed to reliably detonate the composition. Also provided is a method for manufacturing an explosive composition comprised of Heavy ANFO and grain hulls, such as rice hulls. Additionally, a method of using an explosive comprised of ANFO and grain hulls in a mining operation is disclosed.

Abstract: The present invention is direct to a portable audio player that substantially limits a target user to listening to the audio content that was initially established in the player during manufacture or subsequently established in the player under controlled conditions exclusive of the target user. Such an audio player provides missionaries and the like with the ability to provide an audio Bible to potential converts and especially to those potential converts that are incapable of reading a Bible that is in book or text form, such as potential converts that are visually impaired or illiterate. In one embodiment, the audio player occupies less than about twenty cubic inches and weighs less than six ounces. As a consequence, the player is highly portable. The audio player also utilizes a non-sequential-access memory, such as a disk drive and/or flash memory, to store the desired audio content.
