Title: Arc diverter
Inventor: ANDERSON GLEN L
IPC: C23C14/34
Filed: 1991-03-21
Granted: 2000-05-02
Abstract: An arc diverter (10) detects an arc between the cathode (11) and the anode (12) of a glow discharge apparatus and in response, triggers a pair of switches (11, 23) to allow a capacitor (16) to discharge toward the cathode (11) along a resonant diverting path (26) and recharge the capacitor (16) for subsequent discharge in an opposite direction. This discharge current effectively short circuits the power supply and extinguishes the arc. The diverter (10) includes two resonant diverting paths (27, 28) and four switches (20, 21, 22, 23) configured in an "H" to hold the capacitor (16) in a charged condition. Alternate triggering of diagonally situated switch pairs (21, 23) and (20, 22) enables the charged capacitor (16) to discharge in one direction along one of the resonant diverting paths (26 or 27) and recharge for subsequent discharge in the opposite direction, along the other of the resonant paths (27 or 26).

Abstract: A process for controlling the conversion of reactor feed to iron carbide is disclosed. The reactor feed is subjected to a pro-cess gas in a fluidized bed reactor (10), and measurements (56) are taken of individual gases in the off-gas from this reaction and the temperature (64) and pressure (66). A stability phase diagram is generated based on the temperature. Different regions of the stability phase diagram are representative of different products being formed by the conversion of the reactor feed. Based on con-centrations of the individual gases in the off-gas and the total pressure, a point is plotted on the stability phase diagram indicative of the favored reaction product. The process parameters can then be adjusted to insure that iron carbide can be produced from the reactor feed based on the stability phase diagram.

Title: Fluid treatment system and process
Inventor: MAARSCHALKERWEERD JAN M
IPC: B08B3/02
Filed: 1994-03-04
Granted: 1999-02-23
Abstract: ABSTRACT OF THE DISCLOSURE       A fluid treatment system includes one or more radiation sources arranged in an irradiation zone within a treatment zone through which fluid to be treated passes and is irradiated. The irradiation zone has a closed cross-section to maintain the fluid within a predefined maximum distance from the radiation source. Preferably, the irradiation zone comprises a reduced cross-sectional area perpendicular to the direction of fluid flow and thus the fluid flow velocity is increased through the irradiation zone. This allows the fluid to enter the treatment zone at relatively low speed, traverse the irradiation zone at high speed and exit the treatment zone again at relatively low speed to minimize the loss of hydraulic head throughout the system. Fluid entering the treatment zone passes through an inlet transition region wherein the cross-sectional area is reduced prior to entering the irradiation zone and fluid exiting the irradiation zone passes through an outlet transition region wherein the cross-sectional area is increased. Each transition region is designed to reduce hydraulic head losses as the fluid flow velocity is increased and decreased. In the irradiation zone, radiation sources are mounted on radiation modules which are arranged to provide improved accessibility for maintenance. The radiation modules may also be provided with cleaning assemblies which are operable to remove materials fouling the radiation sources in situ while the radiation sources are in the irradiation zone.
