Magneto Patents (Class 324/389)
  • Patent number: 8299936
    Abstract: A method for generating electromagnetic waves in the ELF/ULF comprising the steps of using a ground-based Horizontal Electric Dipole (HED) antenna to send electromagnetic pulses upwardly in the E-region of the ionosphere to form an oscillatory or pulsed electric field; allowing said pulsed electric field to interact with magnetized plasma of the lower ionosphere to generate a pulsed horizontal and vertical current which have associated Horizontal and Vertical Electric Dipole moment; and allowing them to radiate.

  • Patent number: 6693428
    Abstract: For the purpose of providing an RF coil that prevents a troublesome force from arising when a hanging portion is lifted up, a pair of handhold members 308 is provided along a side that corresponds to an inner side of a cylinder 110, each member extending from one end to the other end of one of a pair of flexible substrates 304 so that an operator can lift the hanging portion up using such handhold member.

  • Patent number: 4871970
    Abstract: A test circuit for setting the synchronizatiom of a dual ignition system, particularly of an aircraft engine dual magneto system, having an oscillator circuit 3, two transformers 23, 24 connected to the oscillator circuit, said transformers receiving the oscillator signal at a cener-tap of their primary windings, in which the primary windings are connected at one end to a common potential and having at least two connections for connecting the test circuit to the ignition system to be tested, said two connections each being connected to the other end of the primary winding 23, 24. Secondary windings 27, 28 of the transformers 23, 24 are connected to indicator elements 29, 30.
