Definitions

  • the above difficulty is overcome by connecting a variable self-induction in parallel with a series connection consisting of a loading resistance and the patient with the movable part of the regulating device connected between the patient and the loading resistance.
  • the element 6 toward the right results in greater amperage in the'electrode circuit and 'a'movement thereof toward the left causes a short-circuiting of said electrodes.
  • the electrodes maybe taken from the patient while the apparatus is in full operation without encountering the previously mentioned drawback.
  • many pieces of apparatus as desired, including the elements 6, c, d and 6 may be connected to the source a in parallel.
  • the system may also be arranged for use with two or more patients by the employment of a common loading lamp or resistance.
  • the high frequency current flows from the secondary of the transformer f successively through the electrode 9, the common resist- In parallel with the resistance 71 and with each one of the electrodes g'and a there are located the va-' to the full potential or is short-circuited.
  • the system renders possible, as is apparent, a corresponding extension for more than two patients if distributor resistances are connected to the terminals 9, i, or several pieces of the apparatus, including the elements 9, h,
  • i is, m, n, 0 are connected in parallel.
