20090107036 | COMBUSTIBLE LOG - Combustible log (U) comprising a matrix (M), a first component (A) and a second component (B), the first and the second component (A, B) forming two inserts placed in the gangue forming matrix, the combustion of the first component (A) producing a first effect and the combustion of the second component (B) producing a second effect, the distances between the outer surfaces of the inserts and the outer surface of the matrix (M) being determined so as to introduce a time lag during the combustion of the log (U) between the apparition of the first effect and the apparition of the second effect. | 04-30-2009 |
