There is provided a plasma torch in which a plasma arc emanating from an electrode in a torch body (1) is pinched in a torch nozzle (3) and is then flushed therefrom, characterized in that an axis of said torch nozzle (3) is deviated in position from with a center line of said torch body (1).

A plasma torch can produce a uniform and intense swirl in the operating gas, and as a result further stabilize the output of the plasma jet, which results in good cutting quality, so as to extend the life of consumables or the like. This is achieved when jet ports (3) from which operating gas G is ejected are positioned such that in a transverse cross-section (2A) of a swirler (50) including the jet ports (3), a relationship between a diameter D of a swirler chamber and a minimum distance (d) fr...

A novel polypeptide, designated plasma carboxypeptidase B (PCPB), has been purified from human plasma. It has been cloned from a human liver cDNA library using PCR amplification. Provided herein is nucleic acid encoding PCPB useful in diagnostics and in the recombinant preparation of PCPB. PCPB is used in the preparation and purification of antibodies thereto, in the purification of plasminogen, in the inhibition of plasminogen activation by t-PA in the presence of fibrinogen, and in diagnostic ...

A plasma generation system includes one or more pairs of electrode units. Each electrode unit emits a plasma carrying gas along a respective axis. Each pair of electrode units is connected to an electric power supply that creates an electric discharge through the gas jets emitted by the two units. The axes of the two units define a "basic" plane. Each unit is associated with a magnetic circuit having two poles on the opposite sides of the basic plane. Each of these circuits is used to move the p...

A plasma thermoelement which is built into the immediate volume of a nuclear fuel mass of a nuclear fuel element is described which comprises a snorkel (12) which is surrounded by a nuclear fuel mass (14) which in turn is surrounded by a cladding (16). Both the exit end of the snorkel and the cladding are connected electrically only via an external load. The nuclear fuel mass is formed from a multitude of the ceramic nuclear fuel microspheres (24). The use of plasma as high-temperature conductor...

The invention relates to a device for emission spectrum analysis with an analysis plasma containing the analysis sample and a spectrometer suitable for emission measurements, in which there is a plasma manipulator (4) with a cooled diaphragm (8) concentric with the axis (7) and perpendicular to the direction of expansion of the plasma with a free diameter smaller than that of the plasma which allows only the central part (6) or only the optical part of the analysis plasma to pass and masks off t...

A plasma apparatus generates plasma by introducing electron beams into a processing chamber filled with a reactive gas for irradiation of the reactive gas with the introduced electron beams, to process a substance by the generated plasma. The plasma apparatus has a sample base for mounting the substance to be processed so that a processing surface of the substance is not directed in a direction perpendicular to a travel direction of the electron beams introduced into the processing chamber; a su...

A plasma reactor includes, a) an electrically insulative shell forming a reactor cavity, the reactor cavity having internal walls; b) inductive coils positioned externally of the cavity; and c) a capacitive coupling plate positioned externally of the cavity intermediate the cavity and inductive coils, a power source being operably connected with the capacitive coupling plate. A method of cleaning away material adhering to internal walls of a plasma reactor includes, a) injecting a cleaning gas i...

Components such as an earth plate, a gas introduction ring, and the like placed in a reaction chamber in a plasma apparatus are made of aluminum containing magnesium in a concentration of 2.2 to 2.8% by weight and are not coated with alumite. In addition, a heater incorporated in a section of the reaction chamber heats the section during a plasma cleaning process. Further, an electrical discharge chamber is also incorporated in the plasma apparatus for providing a plasma to the reaction chamber ...
