Abstract: A detonating energy transmittal device is provided which, when combined with even relatively low-power blasting caps, is capable of promoting and initiating the explosive detonation of liquid nitromethane, which device comprises a plurality of layers of foam material, an effective amount of frangible articles carried on at least one surface of the foam material layers and forming thereon a substantially continuous layer intermediate the adjacent foam material layer, and a cavity capable of accommodating a blasting cap and of placing said blasting cap in intimate contact with said plurality of foam material layers. Methods for detonating fluid explosives also are provided.

Abstract: Hydrocarbon-based fuel compositions which provide improved cetane ratings and a method of making them which comprises admixing a major amount of a petroleum fraction of the diesel boiling range and a small, effective amount of at least one compound having the general formula: ##STR1## where R is H, CH.sub.3 or A;R' is H, CH.sub.3 or C.sub.2 H.sub.5 ;A is ##STR2## or is ##STR3## R" is H or C.sub.1-3 alkyl; and x is 1 or 2.
