Title: Operating method for a discharge lamp having at least one dielectrically impeded electrode
Inventor: THIEL GERWIN
IPC: H05B41/24
Filed: 2001-02-01
Abstract: The invention relates to a method for operating a discharge lamp, which has at least one dielectrically impeded electrode (2, 3), on a flyback converter, which applies periodically recurring voltage pulses to the discharge lamp (La1). If the discharge lamp (La1) has a starting aid (10), the voltage amplitude (U S) of the voltage pulses is successively raised until a dielectrically impeded discharge is formed in the discharge lamp, and until the voltage amplitude (U S) has reached the nominal operating voltage. If the discharge lamp (La1) has no starting aid, a first discharge which causes a partial ionization of the discharge medium is firstly ignited in the discharge lamp (La1).      Immediately after the first discharge has been brought back to extinction, a dielectrically impeded discharge is ignited anew, and the voltage amplitude (U S) of the voltage pulses is increased until the nominal operating voltage of the discharge lamp (La1) is reached.

Title: Transmitter circuit with frequency self-optimization
Inventor: GARCIA JOSE MARCELINO
IPC: H04B1/38
Filed: 2001-02-05
Abstract: In a transmitter circuit designed to operate over a specified transmit frequency range, information as to the specific frequency within the specified transmit frequency range at which the transmit up-converter of the transmitter circuit is to be operated, is used to generate a control signal for a high-power amplifier within the transmitter circuit, where the high-power amplifier automatically optimizes its operations based on the frequency indicated by the control signal. For example, for the transmitter circuit of a PCS base station transmitter, control signals received by the transmit up-converter from an alarm control board identify the particular 5-MHZ or 15-MHZ PCS frequency block for the base station transmitter. The up-converter uses that frequency information to generate a two-bit control signal identifying one of three 20-MHZ frequency sub-ranges within the 60-MHZ  PCS forward-link transmit frequency range. The high-power amplifier uses that two-bit control signal to retrieve values from memory for tunable parameters and uses those tunable parameters to optimize its operations, thereby achieving acceptable low levels of intermodulation distortion at any PCS frequency block within the full 60-MHZ  PCS frequency range.

Inventor: WILHELM FRIEDRICH
IPC: F42D5/04
Filed: 2001-03-07
Abstract: The invention relates to a method for disposing of hazardous and high-energy materials. According to the inventive method, these hazardous and high-energy materials are introduced into the interior of a pressure-proof housing (2) which is additionally charged with bulk material, for example in the form of steel or ceramic balls. The mixture of bulk material and material to be disposed of forms a fluidized bed (16) within the pressure-proof housing (2). Said fluidized bed fills the pressure-proof housing (2) always in substantially the same manner in a dynamic balance between supply and discharge. The reaction by which the hazardous and high-energy materials are converted to harmless substances is optionally initiated by a specific device, for example a fuse (18), at a defined distance to the surface in the interior of the fluidized bed (16). In the course of said reaction, the fluidized bed (16) absorbs thermal and mechanical energy that is released during the reaction. After having passed the fluidized bed (16), the reaction is entirely completed so that a mixture of bulk material and residuals stemming from the reaction can be removed from the bottom of the fluidized bed (16). The invention provides a continuous and risk-free method of disposing of such materials. For reactions that are initiated by the addition of heat it even can be carried out in an energy-saving manner due to the storage effect of the bulk material.

IPC: G11C8/18

Abstract: A memory controller providing a synchronous SRAM interface to an embedded DRAM is disclosed. To achieve maximum performance DRAM timing, control logic is emulated in the controller to produce DRAM control signals. Control signal timing can be flexibly adjusted using control registers. The memory controller's interface and the DRAM's interface operate in separate clock domains. In other words, since the timing of DRAM control signals is asynchronous from the interface clock and based on the embedded DRAM timing emulation, all margins can be minimized. The SRAM interface can operate in a wide range of clock frequencies, which are not restricted to ratios of multiples of the embedded DRAM clock frequency. The controller produces the DRAM clock signal asynchronously with respect to the interface clock. Therefore improved DRAM performance is achieved without modifying the embedded DRAM logic, to improve performance of the system in which the DRAM is embedded within.

IPC: C25B15/08
Filed: 1999-09-01
Abstract: An efficient method of producing hydrogen by high temperature steam electrolysis that will lower the electricity consumption to an estimated 65 percent lower than has been achievable with previous steam electrolyzer systems. This is accomplished with a natural gas-assisted steam electrolyzer, which significantly reduces the electricity consumption. Since this natural gas-assisted steam electrolyzer replaces one unit of electrical energy by one unit of energy content in natural gas at one-quarter the cost, the hydrogen production cost will be significantly reduced. Also, it is possible to vary the ratio between the electricity and the natural gas supplied to the system in response to fluctuations in relative prices for these two energy sources.  In one approach an appropriate catalyst on the anode side of the electrolyzer will promote the partial oxidation of natural gas to CO and hydrogen, called Syn-Gas, and the CO can also be shifted to CO2 to give additional hydrogen. In another approach the natural gas is used in the anode side of the electrolyzer to burn out the oxygen resulting from electrolysis, thus reducing or eliminating the potential difference across the electrolyzer membrane.

Title: Mercaptoalcohol corrosion inhibitors
Inventor: JOVANCICEVIC VLADIMIR
IPC: C09K8/54
Filed: 2000-08-11
Abstract: Compositions and methods have been discovered for inhibiting corrosion of metals, particularly iron alloys, in con-tact with fluids, either hydrocarbons, alcohols, or aqueous fluids, employing mercaptoalcohols. The mercaptoalcohols should have at least one water solubilizing hydroxyl group. In particular, suitable mercaptoalcohols have the formula: (HS)n-R-(OH)m where R is a straight, branched, cyclic or heterocyclic alkylene, arylene, alkylarylene, arylalkylene, or hydrocarbon moiety having from 1 to 30 carbon atoms; n and m each independently averages from t to 3; and the heteroatom in the heterocyclic moiety substituent, if present, may be N, O, S and/or P. Preferred mercaptoalcohols include 2-mercaptoethanol, 2-mercaptopropanol, I-mercapto-2-propanol, and 2-mercaptobutanol, in part because they are soluble in many fluids. These corrosion inhibitors show improved inhibition of both generalized and localized corrosion, specifically in high shear and high flow environments.
