    摘要: A line storage device prevents a line from becoming entangled. A channel formed in a piece of material defines a non-overlapping zigzag pattern. The line is laid in the channel and extends from opposing ends of the piece of material. The material supports the line in the channel until the line attains a threshold tension at which point the piece ruptures sequentially along the zigzag pattern from each opposing end. The channel can be formed in or on one or more surfaces of the piece of material.

    摘要: A magneto-inductive submarine communication system and buoy provide two-way signal communications between a submerged craft, such as a submarine and remote command station that may be airborne, on the surface, or on land. A buoy released from the submarine and floating on the surface of the ocean and a satellite is included to complete the bidirectional communications. Messages and commands between the submerged craft and the buoy are communicated by magneto-inductive message signals and magneto-inductive command signals in the extremely low frequency (ELF) to very low frequency (VLF) range of less than 3000 Hz. Message and command communications between the buoy and the satellite (or aircraft, or helicopter, or surface ship), and the satellite to the station are transferred via radio frequency (RF) signals or laser emissions.

    摘要: A reusable gas-powered hand grenade is provided. A hand-held housing defi one or more launch tubes. A projectile is loaded in each launch tube with an obturator being positioned therein between the projectile and the launch tube's muzzle end. A sealed reservoir is maintained in the housing for storing a gas under pressure. A rupturing device is mounted in the housing for breaking the reservoir's seal upon impact therewith. A triggering mechanism coupled to the rupturing device maintains separation between the rupturing device and the seal until the triggering mechanism is activated. Once activated, the triggering mechanism moves the rupturing device to impact the seal so that gas pressure propels the projectile and obturator from the launch tube.
