| A method is described for detonation of a blasting charge in a fluid environment and which is placed inside a hollow body, such as in an ignition pellet. The method is characterised in that an ignition pellet is used, which is arranged to be deformed under the influence of a number of alterations or pulsations between high and low pressure in the surrounding fluid environment, with the detonation triggering unit inside the body being activated at the subsequent contact with the fluid environment as a consequence of the pellet being deformed. In rupturing, external fluid at overpressure is released into the cylinder and drives a firing pin against a detonating cartridge. A device for an ignition pellet is also described. | ||||||

| An explosive device contains a water-reactive material that ignites upon exposure to water. The water-reactive material ignites a water-activated fuse that has a predetermined burn rate and length. The predetermined burn rate and length allows the device to sink to a desired depth before exploding. Hence, the device explodes after a desired period of time and/or at a desired depth. Defense against underwater swimmers is an advantageous feature of embodiments of the disclosure. The device can use a forty millimeter (40 mm) form factor, which permits launch of the device from convention grenade launchers. | ||||||

| A method for detonation of a plug device in a fluid environment is described, which is in contact with a body, such as an ignition pellet, and it is characterized in that a number of pressure increases are exerted against the plug device, whereby each pressure increase causes a movement of a piston (10) which is radially arranged in a casing (12), which causes the casing (12) to move a fixed distance inward in the plug device with each pressure increase, up until the displacement of the casing (12) causes the piston to be displaced into a cavity (38), and the fluid environment enters the plug device via an inlet. Also described is a plug device which is in contact with a body, such as an ignition pellet, where the plug device is arranged to detonate after a number of pressure increases that are exerted against the plug device. The plug device/ignition pellet can be applied to initiate a detonation process which leads to perforation of a pipe wall or to perforate or remove/explode plugs in oil wells or gas wells, thereby starting production from a reservoir through a pipe. | ||||||

| An explosive actuated acoustic device emits sound to be used in torpedo countermeasures. Numbered devices are delivered over an extended area and sink through the water. The devices are actuated at different times as they sink, to provide sound masking over an extended period of time. The devices also include safety devices which prevent premature actuation from jarring or jolting and from impact with the water. | ||||||

| A pressure-actuated secondary arming interlock for use in a bomblet fuzing device. The interlock consists essentially of a diaphragm-type snap spring and a locking pin which interlocks with the primary arming apparatus and prevents it from arming until the pressure actuated interlock is first exposed to a highpressure environment. Upon experiencing the proper environment, the diaphragm-type spring snaps into a position which disengages the pin from the primary arming apparatus placing the fuzing device in a condition for arming.
