Definitions

  • invention relates to recording apparatus for the transmission of pictures by radio or on wire circuits in which the recording of the incoming picture is effected electro-chemically by virtue of the separation of suitable coloring ingredients by the aid of a current caused to pass through the 7 recording surface which is, rendered conductive.
  • the object of the present invention is to provide ways and means to record the incoming picture upon a continuously travelling picture strip or film so that the use of a complicated picture drum or cylinder may be dispensed with.
  • Fig. 1 represents one form of roller adapted to our invention, and;
  • Fig. 2 is a modification of the showing of Fig. 1 wherein, the roller is provided with a thick layer of rubber in which the contacting strip is placed.
  • a revolving cylinder 1 is employed. Upon the circumference of this cylinder a conducting edge 2 in, spiral shape is secured.
  • the conducting edge preferably The prese forms one pole of the recordingor repro ducin device.
  • the recording surface consists, for instance, of a stri or film of paper 3 soaked or impregnated with a suitable electrolyte.
  • the film 3 is directed over a currentconducting straight edge 6 having the length of the metal cylinder.
  • the straight edge is arranged parallel to the metal cylinder 1 at the same height as the axis of the latter, and is so disposed that it bears with a slight amount of pressure against the spiral edge 2.
  • the straight edge parallel to the cylinder axis forms the second pole for the feed of the suitably amplified incoming current, which is so directed as to flow from the straight edge through the impregnated paper to the spiral edge. If, then, the said metallic 4 cylinder is turned about its axis 4, the spiral edge 2 during each rotation rolls once at uniform rate of speed along the straight edge, or, in other words, the point of passage 1927,.Seria1 No. 228,155, and in ,Germany October 29, 1926.
  • the spiral edge which has suitably the form of a platinum wire 2, or of a wire of other strong and resistant material laid around the writing cylinder, is not brought upon a rigid cylindrical surface, but p the said surface is made yielding and elastic. This is done most simply by subjecting the cylinder to a vulcanizing treatment, for example.
  • the cylinder 1' is coated with a suflicient thick layer of rubber 5.
  • the wire 2 is there embedded in a shallow groove cut in said rubber layer, although the said groove may be dispensed with, provided the material possesses sufficient inherent softness. At such places where due to greater thickness of the writing or inking material or mechanical imperfect-ions, undue pressure should arise, the elastic rubberlayer is caused to yield, and the assembly is thus adjustable in such a way that good and tact is insured throughout the entire line.
  • a pictureinking apparatus adapted for electro-chemical recording or reproduction comprising, a rotary cylinder, a resilient yet yielding con- 1 lam layer placed around said cylinder, a currentsaid second current-conducting edge, said conducting edge spirally wrapped around paper being adapted upon rotation of said said cylinder, said current-conducting edge cylinder to be moved forward, whereby vari- 10 resting upon said resilient surface, a second ations in currentv are progressively recorded.
  • 5 current-conducting edge extending adjacent and parallel said cylinder, and a paper strip PETER SCHNITZELER. between said spirally conducting edge and AUGUST KAROLUS.
