Abstract : The patent relates to a device whereby two lengths of metal-sheathed explosive-detonating cord are placed on an aluminum plate in side by side position to form a double length portion of cord intermediate their ends. One end of each length of cord is secured to a body of explosive for initiation in response to detonation of the body. A detonator, attached to the body near one of the secured cord ends, detonates the body which initiates the cord lengths. Initiation fronts, travelling along the cord length, form offset or lateral marks in the aluminum plate where the fronts meet. The mark location relative to the cord lengths, detonation velocity of the cords and the distance between the secured ends enables a very accurate determination of the detonation velocity of the explosive body.
