Abstract: A telecommunication base station transceiver subsystem that can be easily configured to provide single or multi-carrier frequency service. The base station is divided into a main unit and a radio unit such that the radio unit is positioned proximate to the antennas and the main unit is remotely located from the radio unit. A single base station transceiver can provide service via multiple wireless protocols, such as CDMA, TDMA, GSM or Analog. The base station transceiver .can also operate on various transmit/receive frequencies as well as variable transmit power settings. Furthermore, the base station transceiver can be reprogrammed, reconfigured and/or statused by a network operations center.

Abstract: The present invention includes a conceptually new process to produce primary aluminum through the modification/adaptation for the HHC of a non-consumable anode of the type used for solid oxide fuel cells (SOFC) with the provision to electrochemically utilize/burn a fuel. The present invention is believed to work most effectively when the dissolution and fragility problems of the zirconia-base solid electrolyte can be sufficiently alleviated, e.g., through the use of a lower electrolysis temperature, through the use of melt additives to restrict dissolution, and/or through modem methods for the fabrication/deposition of the electrolyte onto an appropriate internal metal anode. The present invention thus achieves, through the use of the solid-electrolyte-coated anode, the long-sought non-consumable anode. The electrochemical oxidation, inside the NCA in accordance with the present invention, of an inexpensive fuel, e.g.

Abstract: Offgas recycling processes, including an argon degassing embodiment which cyclically regenerates one treatment flow path while the other treatment flow path is treating the offgas. The system is changed into a second mode to regenerate the previously treating portion of the system while the offgas is being treated by the previously regenerated treatment device. A second embodiment oxidizes a copper chloride bed to release chlorine, which is injected into the melt. The offgas contains chlorine and HCl, which react with a second bed, containing oxides of copper, forming copper chloride. Water vapor and nitrogen are exhausted to the environment. Before the beds are fully reacted, the flow of gas through the beds is reversed, oxidizing the CuCl bed and reducing the copper oxides.

Abstract: A method for the simultaneous deposition of chromium and silicon to form a diffusion coating on a workpiece uses a halide-activated cementation pack with a dual halide activator. Elemental metal powders may be employed with the dual activator. A two-step heating schedule prevents blocking a chromium carbide from forming at the surface of the workpiece. Small contents of either Ce or V can be added to the Cr+Si contents of the coating by introducing oxides of Ce or V into the filler of the pack.

Abstract: Diffusion coatings incorporating approximately 18 to 35 wt % Cr and 1 to 3% Si in 2.25Cr-1.0Mo steel and 1018 steel have been produced using a pack cementation method. The codeposition of these concentrations of Cr and Si into the 2.25Cr-1.0Mo and 1018 steel requires the use of a "mixed activator" (fused salt solution of NaF and NaCl). Cyclic oxidation tests in air at 700.degree. C. of a coated 2.25Cr-1.0Mo steel coupon with a surface concentration of 34Cr-3Si have shown excellent cyclic oxidation resistance. Furthermore, a 1018 coupon coated to a surface concentration of Fe-30 wt % Cr-3Si shows negligible aqueous corrosion in an aerated 3.5% NaCl solution at room temperature. These coatings have provided similar protection in more complex oxidizing and reducing atmospheres.
