Abstract: Presented is a system and method for disconnecting a plurality of wireline tools from a string of wireline tools while maintaining operation of the wireline tools remaining with the string of wireline tools. The disconnection is non-destructive and allows a reconnection of the disconnected tools after retrieval from the well. The system also enables testing of the disconnection mechanism before deploying the wireline tool string into the well.

Abstract: A survival weapon is described in which a projectile firing weapon mounts a stock member. A connector mounts the stock member to the projectile firing weapon for selective motion between an inoperative position in which the stock member is positioned in juxtaposition to the projectile firing weapon, and an operative position in which the stock member projects outwardly of the projectile firing weapon. The stock member includes compartments releasably receiving survival items such as a fire starting component, a cutting tool, a direction finding device, and ammunition for the projectile firing weapon. An access opening is formed in the stock member that is aligned with the trigger of the weapon and that provides access to the trigger when the stock member is in either the operative or inoperative position. A saw blade and a chopping head may also be provided for attachment to the stock member to enable use of the stock member as a saw or chopping tool.
