    Abstract: Apparatus and method for cooling a component inside a tool includes a container and a plurality of heat sinks positioned in the container. The components are positioned in the container with the heat sinks for maintaining a reduced temperature inside the container. Further, an insulating layer and a reflective layer surround the heat sinks and components to reduce heat transfer. Alternatively, the container can have a hollow wall that encloses the space in which a heat sink material (such as an eutectic material) is disposed. The components to be protected are located in the container. The eutectic material includes a composition having tin and zinc. The insulating layer includes a container that stores a vacuum layer, such as a dewar flask.

    Abstract: A structure for attenuating explosive shock waves to prevent propogation of accidental explosions by sympathetic detonation of adjacent explosives comprising bidirectionally symmetric layers of material of consecutively increasing or decreasing acoustic impedance laminated about a center layer. The structure may be made by combining several materials, as in consecutive layers of aluminum, plastic, and a rigid foam surrounding on both sides a layer of steel; or, two materials, as in a center layer of Kevlar.TM. surrounded on both faces with layers of plastic. The plies comprising the layer of Kevlar.TM. are canted with respect to the plastic layers.

    Abstract: A safe and arm device, which has an explosive train interrupted by a void establish a safe condition, has the void filled with a liquid explosive to establish an armed condition. The void may be in a device in which the liquid explosive is motivated by fluid pressure corresponding to free-fall or other velocities. The void may be a chamber portion filled with the liquid explosive by expansion of a bladder. Premature arming may be prevented by forming the explosive liquid from nonexplosive liquids mixed by rupture of a bladder or by melting a solid explosive.

    Abstract: A method of combining explosive compositions prepared from commercially available nitric acid and a common industrial solvent is disclosed herein which exhibits exceedingly high blasting strengths. The compositions are relatively more stable than conventional shaped charge explosives such as HMX or RDX and far less expensive. The compositions are transported separately to the blasting site where the compositions are combined in ambient temperature for immediate use.

    Abstract: An intrinsically non-explosive liquid constituent of an explosive composition is contained within a can. The can is located inside of a plastic bottle. In the field an intrinsically non-explosive solid constituent of the explosive composition is poured from a separate container into a space in the bottle above the cam. The user presses down on the capped top of the bottle to move a downwardly projecting cutter carried by an upper portion of the bottle downwardly and through the top of the can. Following cutting the bottle is turned upside down and/or shaken to cause a mixing of the two constituents of the explosive composition. The resulting explosive is a liquid which can be poured from the bottle and then detonated by a conventional detonator, or detonated while still in the bottle.
