Abstract
205,068. Soc. Fournier et Cie Oct. 3, 1922, [Convention date]. Pencil and like holders.-A glass tube F containing helium under low pressure has a single electrode E, consisting of a cast aluminium ball or disc on the end of a platinum wire, connected by a spring D to the black-lead holder C of a pencil holder. The vacuum tube F is introduced into the ebonite casing A of the pencil holder at the upper end, which is then closed by a screwed cap G. When the black-lead point of the pencil is applied to a high-tension circuit in which sparking is taking place, the tube F becomes luminous.
