摘要： The present invention generally provides a method for prevention of corrosion in a metal object by inducing a surface current over the entire surface of the metal object. The surface current can be induced by direct or indirect application of electrical waveforms having AC components generated from a circuit. The metal body and the negative terminal of a source of DC voltage (battery) are grounded. The positive terminal of the source of DC voltage is connected to the electronic circuit that imparts electrical waveforms of low voltage DC to the conductive terminal connected to the metal body. Alternate methods of inducing surface currents include direct capacitor discharge through the metal body, or movement of an electromagnetic field over the metal body, or by generating an RF signal attached to a transmitting antenna such that the transmitted signal is received by the metal body.

摘要： Methods and apparatus are provided for igniting, modulating, and sustaining a plasma for various plasma processes and treatments. In one embodiment, a plasma is ignited by subjecting a gas in a multi-mode processing cavity to electromagnetic radiation having a frequency between about 1 MHz and about 333 GHz in the presence of a plasma catalyst, which may be passive or active. A passive plasma catalyst may include, for example, any object capable of inducing a plasma by deforming a local electric field. An active plasma catalyst can include any particle or high energy wave packet capable of transferring a sufficient amount of energy to a gaseous atom or molecule to remove at least one electron from the gaseous atom or molecule, in the presence of electromagnetic radiation.

摘要： A method for controlling the non-uniformities of plasma-processed semiconductor wafers by supplying the plasma with two electrical signals: a primary electrical signal that is used to excite the plasma, and a supplemental electrical signal. The supplemental signal may be composed of a plurality of electrical signals, each with a frequency harmonic to that of the primary signal. The phase of the supplemental signal is controlled with respect to the phase of the primary signal. By adjusting the parameters of the supplemental signal with respect to the primary signal, the user can control the parameters of the resultant plasma and, therefore, control the non-uniformities induced in the semiconductor wafer.

摘要： An oil separator usable with a welder and air compressor combination unit. The oil separator includes a cylindrical housing having an inlet that receives the stream of compressed air containing oil from the air compressor. Within the oil separator, there is a deflector baffle that redirects the flow of the oil to a swirling, downwardly directed path along the inner surface of the cylindrical housing where the air is separated out therefrom and passes upwardly to exit through a fluid outlet formed in the cover of the separator. The swirling oil flows downwardly through an annular slot formed between a circular plate and the inner surface of the cylindrical housing into a lower chamber where the oil is channeled by radially directed baffles into radial channels to redirect that oil toward an oil outlet at the center of the circular bottom where that oil exits to be re-circulated in the combination unit or for disposal.

摘要： A device to place an incision into matter with a harmonious plasma cloud. A radiofrequency generator system produces pulsed or continuous electromagnetic waveform which is transmitted by an active transmitter incising electrode tip. This generated electromagnetic wave is utilized to initiate a plasma cloud with processes such as thermal ionization and a photoelectric effect which then trigger an Avalanche Effect for charged atomic particles at the surface of the active transmitter incising electrode tip. This electromagnetic wave is impedance matched, frequency matched, power matched and tuned to the plasma cloud in order to sustain and control a harmonious plasma cloud with reduced atomic particle turbulence and chaos. This harmonious plasma cloud forms a coating over the surface of the active transmitter electrode tip as well as acts to reduce the energy needed from the power amplifier of our plasma cutting device. The electromagnetic wave is also used to produce a Pinch Effect to compress, contour, shape and control the harmonious plasma cloud. The electromagnetic wave is furthermore used to trap and contain the plasma cloud without the need of a solid matter containment vessel according to the Magnetic Bottle Effect of physics and a generated centripetal electric field force that acts to pull plasma particles inward toward the activated incising electrode tip. The Tunnelling Effect of physical chemistry is utilized to focus and amplify the energy delivered to the harmonious plasma cloud while shielding matter surrounding the intended path of incision from potential electromagnetic radiation exposure. The invention is an efficient, effective, safe, clean and inexpensive device which can be used to place an incision in matter.

摘要： A boss for attaching to a manufactured hole in a pipe has a generally cylindrical hollow body, with an external surface and an internal surface, a first end and a second end. The second end has a smaller external diameter than a diameter of the external surface. The second end aligns with the hole, and has pointed protrusions, for concentrating a weld spark during welding. The external surface is stepped forming a larger diameter portion adjacent the first end and a smaller diameter portion adjacent the second end. The smaller diameter portion has a diameter larger than the diameter of the second end. Alternatively, the second end has a bevelled portion cooperating with a pointed end of the hole, or a skirt generally conforming to the profile of the pipe, the skirt having pointed protrusions, for concentrating a weld spark during welding.

摘要： In a process for producing a welded joint between the ends of two metal strips in which the butted ends are connected by means of a TIG welder that can be moved perpendicularly to the longitudinal direction of the metal strips, one sheet metal piece each is placed in the area of the butt joint along the longitudinal sides of the metal strips. The two sheet metal pieces are tack-welded to the longitudinal edges of the metal strips in the joint area by means of a spot weld of the TIG welding unit. The strip ends are welded together by moving the welder along the joint edges. The welder is activated on one of the sheet metal pieces and moved up to the opposite sheet metal piece, and the two sheet metal pieces are removed from the longitudinal sides.
