Definitions

  • the present invention has for its object means reducing substantially the length of the writing head and chiefly cutting out any deformation of the character to be drawn, which deformation is ascribable to the duration of progression of the jet of ink as it passes between the first pair of electrodes and then between the second pair, in the case where said two pairs of electrodes are located in sequence along the path of the jet of ink.
  • the voltage applied to the tube 9 is transmitted either by the conductive ink or else by a metal lead which may, as a matter of fact, b inserted inside the yielding pipe 10.
  • the electricfields inside said head remain valways uniform and their values are well-defined. Said fields can be deformed neither by. outerparasitic fields, nor under the action of the, static loads which may collect on the insulating parts.
