Abstract:
An electrodeless lamp comprises an envelope (12) containing a plasma forming fill which includes at least one of sulfur and selenium when excited which emits principally visible light, which is in the form of molecular radiation. The envelope (12) has a diameter of less than one half inch. Means (1) are provided for generating electromagnetic energy. Further means (2, 3, 4, 5, 6) are provided for coupling said electromagnetic energy to said envelope to excite said fill, which in the absence of envelope rotation or with rotation at an insufficient speed, forms a discharge (14) which does not substantially fill the interior volume of said envelope (12). By additional means (13) the envelope (12) is rotated at a fast enough rate so as to cause the discharge (15) formed by the fill to substantially fill the interior volume of the envelope (12).

Abstract:
A diverging magnetic field (52) is established between the cathode (20) and the control electrode (30) of a hollow cathode plasma switch to expand the plasma at a passageway (32) through the control electrode, thus significantly increasing the switch's current handling capability. Preferred ranges of magnetic field strength, gas pressure, spacing between the hollow cathode (20) and the control electrode (30), and the mesh aperture size for a control grid in the passageway (32) are described.
Abstract:
An electrodeless lamp bulb (12) is rotated at sufficient rate to obviate isolated discharges. A coaxially excited electrodeless lamp bulb (12) is rotated in such manner that different regions of the bulb are near the high field region caused by the inner coaxial conductor, thus preventing are attachment from occurring. An electrodeless lamp bulb (12) is rotated at a high speed sufficient to improve lamp efficiency and reduce cooling requirement. An electrodeless lamp bulb (12) is provided with wall of reduced thickness at the area of the bulb (12) where it is desired to condense the fill upon turning off the power, thus providing for quicker starting.
Abstract:
A starting aid for an electrodeless high intensity discharge (HID) lamp (10) comprises at lease one starting electrode (12) which, at least during lamp starting, is situated adjacent to, and preferably in contact with, the portion of the arc tube (14) nearest the arc discharge (20) and oriented so as to provide a capacitive starting current that flows in substantially the same location as the arc discharge, thereby easing the transition from a relatively low current glow discharge to a relatively high current, high intensity discharge. The starting aid comprises one or more conductors that substantially conform to the shape of the arc tube at least during initiation of the arc discharge. After the lamp is started, the starting aid may be moved to a predetermined location away from the arc tube. Alternatively, the starting aid may comprise one or more fixed starting electrodes. The starting aid may be coupled to the lamp ballast circuit (18) used to drive the excitation coil (16) either directly, or via an impedance network, or via the excitation coil. In an alternative embodiment, the starting aid is excited by a starting circuit that is separate and independent from, and operates at a substantially higher frequency than, the lamp ballast.
Abstract:
Electrical oscillations in a metallic "sending coil" radiate inductive photons toward one or more "energy-magnifying coils" comprised of a photoconductor or doped semiconductor coating a metallic conductor, or comprised of a superconductor. Electrons of low inertial mass in the energy-magnifying coil(s) receive from the sending coil a transverse force having no in-line backforce, which exempts this force from the energy-conservation rule. The low-mass electrons in the energy-magnifying coil(s) receive increased acceleration proportional to normal electron mass divided by the lesser mass. Secondarily radiated inductive-photon energy is magnified proportionally to the electrons' greater acceleration, squared. E.g., the inductive-energy-magnification factor of CdSe photoelectrons with 0.13× normal electron mass is 59×. Magnified inductive-photon energy from the energy-magnifying coil(s) induces oscillating electric energy in one or more metallic "output coil(s)." The electric energy output exceeds energy input if more of the magnified photon-induction energy is directed toward the output coil(s) than is directed as a counter force to the sending coil. After an external energy source initiates the oscillations, feedback from the generated surplus energy makes the device a self-sustaining generator of electric power for useful purposes.
Abstract:
A system and method for growing and controlling an electric arc from an electro-magnetic field generator is described. The arc may be formed substantially straight by growing from successively generated electric fields from electro-magnetic generator, such as a waveform-controlled solid state Tesla coil. The growth and direction of the arc may be controlled by forming a low impedance channel created by an area of focused laser light in the path of the growing arc.
