Abstract: An isotope separator includes a cylindrical chamber having first and second ends, and a length “L.” Inside the chamber, an E×B field is applied to produce plasma rotation. The energy in the plasma rotation is chosen to be much higher than the electron temperature which is clamped by radiation. As the plasma then transits the chamber through the length “L”, the electrons cool the thermal temperature of the isotope ions while maintaining the rotation. Under these conditions, the minority and majority isotopes become substantially separated from each other before they exit the chamber. To achieve this result, E×B is determined using mathematically derived expressions and, in compliance with these parameters, the length “L” of the chamber is determined so that the plasma residence time in the chamber, &tgr;1, will be greater than the cooling time, &tgr;2 (&tgr;1>&tgr;2) necessary to affect isotope separation.

Abstract: An element management system (EMS) for monitoring elements of a communication network utilizes a plurality of clients, a plurality of network elements, and an element management system (EMS). The clients and the network elements are interfaced with the EMS. The EMS is configured to track which of the network elements are of interest to the clients and to automatically monitor the network elements based on which of the network elements are determined, by the EMS, to be of interest to the clients. The EMS is further configured to provide the clients with information indicative of the monitored elements. Furthermore, the EMS may be configured to store graphical user interface (GUI) code that can be utilized to provide a GUI for monitoring and/or changing a network element. The EMS may provide the GUI code to the clients on demand and may enable a user to update the GUI code stored at the EMS.

Abstract: A filter and a method for separating ions in a partially ionized plasma according to their mass includes a chamber with crossed electric and magnetic fields established therein. A feed, including metal atoms having ionization potentials in a low range, and gas atoms having an ionization potential in a high range, is introduced into the chamber. An electron temperature below the low range is generated to partially ionize the feed by dissociating the metal atoms from the gas atoms, and by ionizing the metal atoms into light and heavy ions according to their mass to charge ratio. The light and heavy ions are then influenced by the crossed electric and magnetic fields to separate the light ions from the heavy ions.

Abstract: A multi-mass filter for separating particles of a multi-species plasma includes a chamber, which defines an axis. A radial electric field is crossed with a magnetic field (E×B) to move the particles of different mass (M1, M2 and M3) on respective trajectories into respective first, second and third regions. Specifically, particles M1 are confined in the first region, while both particles M3 and M2 are ejected from the first region into the second region and only the particles M3 are ejected from the second region into the third region.

Abstract: A device for generating a plasma includes an enclosed chamber and an antenna positioned adjacent the wall of the chamber. A ceramic shield is mounted on the wall, with the antenna located between the wall and the ceramic shield. There is also a barrier that is mounted on the wall with the ceramic shield being between the barrier and the antenna element. An alternating voltage source is provided to energize the antenna element to generate a plasma in the chamber. In operation, the ceramic shield isolates the antenna from the plasma in the chamber, and the barrier prevents the deposition of material components from the plasma on the ceramic shield.

Abstract: A system and method for initiating and maintaining a plasma in a chamber, in accordance with the helicon dispersion relation, requires an antenna for radiating RF energy into the chamber. An interferometer, or some similar device, is used in the system to monitor the plasma density level in the chamber, as the plasma is being produced. The plasma density level is then used to control the variable characteristics of the RF energy in accordance with the helicon dispersion relation.

Abstract: A multi-mass filter for separating particles according to their mass-charge ratio includes a chamber for receiving a multi-species plasma that includes particles therein having different mass-charge ratios (with M1<M2<M3). Inside the chamber, which defines an axis, a radial electric field is crossed with a magnetic field (E≦B) to move the particles (M1, M2 and M3) on respective trajectories into respective first, second and third regions. For one embodiment, the filter is configured so that az2Bz is held constant in the expression for cut-off mass, Mcz=eaz2Bz2/(8Vctr). For this embodiment, only the heavier particles M3 are ejected into the third region (M3>Mc3) and only the intermediate particles M2 are ejected into the second region (M2>Mc2). In another embodiment, the radial electrical field is increased outwardly from the axis to a radial distance a2 (r2) at a first rate.

Abstract: An AC glow plug system is provided that includes a static converter for DC to AC conversion.

Abstract: A glow plug shield centrally receives a glow plug which, typically, has a silicon nitride surface. The shield and plug are spaced radially from a fuel injector disposed centrally of a cylinder head. The shield and glow plug extend into a combustion chamber where the shield has an oblique end exposing the circumferential portion of the plug which faces the injector. This shield configuration protects the glow plug from cooling by inlet air, increases the residence time of air/fuel mixture around the plug, and improves flame propagation so that plug temperature and electrical power can be reduced to extend glow plug life. The shield has a coating exteriorly and interiorly covering the portion of the shield extended into the combustion chamber. The coating is of thermally insulating, high temperature resistant ceramic material and acts as a thermal barrier to further reduce glow plug cooling.

Abstract: A process is disclosed for inhibiting enzymatic browning in raw, peeled potatoes comprising dipping the potatoes in a solution of heated organic acids (45-65.degree. C.), followed by treatment in a weakly basic solution to neutralize the potato surface and treatment with reducing agents, followed by storage in modified atmosphere packaging. The process may comprise two stages, in which sodium erythorbate in solution (approximate pH 7.8) is used both as the neutralizing agent and the reducing agent. Alternatively, the process may comprise three stages, in which a solution of the salt of an organic acid (such as sodium citrate) is used to neutralize the potato surface following the heated acid dip, and a third stage containing the reducing agents sodium erythorbate and erythorbic acid are combined at a final pH of greater than 4.3. Chelating agents or sequestrants may be added to the solutions.
