In the above-mentioned embodiment, the bundle of light curtains is diaphragmatic between the two “weeds of a loop” 1, the plane of which lies in the direction of the Eraftlinifen connecting the poles 2.3 dbs of anchors. The wire forming the loop has a circular cross-section in the drawing The loop is stretched between the isolated fixed points 4,, 5 and 6, and the parts of the wire between the poles 2j3, w @ ra. en by isolated ScJan-eläea? # § parallel to «inmate ^ eiii.t« n.

When the "loop JT" is ^{modulated by a 1} ', current flows through it, its branches deform in the direction of the "arrows J ¹ I, I'2, and since the bundle of rays between the turns of the Loop at an '"angle ^; '· perpendicular to the "plane of the loop' against a stationary vertical plane is thrown, it .is understood that .'die [ _'(Schieife, a' G-tar forming it, more or less light äurchl; -5sst · -Aua. For this reason, the flattened cross-sectional f osmi of the wire is recommended.
