Abstract: The invention relates to a smoke composition comprising between 0.05 and 5% of one or more active ingredients, for an effective dose of active ingredient(s) of between 0.5 mg/m3 and 40 mg/m3, and a smoke base. According to the invention, the aforementioned smoke base comprises at least one oxidising agent, one reducing agent and one mineral filler. The mineral filler represents at least 25% of the weight of the base while the reducing agent represents at most 16% of the weight thereof, and the weight ratio of oxidising agent to reducing agent is at least 3/1.

Abstract: A device for relieving mechanical loads on electrical conductors and line poles. The device includes arms pivoted to one another and a rod connected to the arms so that upon pivoting movement of the arms towards a full open position the rod is elongated. An indicator link is provided for indicating deformation of the rod.
