Show PICTURES SENT BY WIRE. Apparatus i by Which Fhotogrnphs or Sketches Aro Transmitted. Trans-mitted. Picture tol8Krani3 havo been wired from Nurcmbm-g to Munich, 100 mllcu nway, ami apparently could havo boon sent ten times that dlatancd with equal eat,. In Prof. Kuril's apparatus the. sketch or photograph must bo translucent, anil Is attached to a cylinder of Klaba mounted on an nxl3 by which It Is slowly rotated, moving at tho snmo tlmo from rlplit to left In filet, moving much as tho wa cylinder cylin-der In tho phonograph does. A beam of light Io directed on the cylinder 'and -uulus through It, modified by the l.u-,--e on that particular coll within with-in tho c.i'.iuer. This cell forms part of an electric circuit. Thu reslatnnco of a selenium coll varies according to tho light falling upon It, and hi this way tho current flowing In the circuit of which tho lino forms a part Is inodliled. 1 h.o receiving apparatus consists of similar cylinder revolving revolv-ing synchronously with tho first with photographic paper fas'tened outsldo It, and with a Nemst electric lamp occupying tho plnco of tlio selenium cell. Tho light of tho lamp fluctuates In unison with the light falling on tho selenium, and ro nffocts tho paper and reproduces on It thu Imago on tho first cylinder. |
