Abstract

187,455. Wanklyn, F. L. Oct. 25, 1921. Pyrotechnic apparatus. - A detonating signal for railways has a container of pyralin formed in two parts, a flat base b and a moulded cover d. This holds the detonator e and the flash-light powder f, and the flange g of the cover is merged with the base b by the use of acetone as a solvent. The entire container is coated with asbestos cement or other fire-resisting substance.
