Abstract: A spinning rotor for an open-end spinning frame has a coating of a non-ferrous metal with hard material granules embedded therein, which is applied to the surface of the base material (12), in particular a nickel layer with diamond granules, wherein the coating is comprised of at least two layers (7, 10) containing hard material granules, and an intermediate layer (9) free of hard material granules between the layers (7, 10) containing hard material granules. In case of a separation in places of the wear protection layer, such as can be caused by a scraper in the course of cleaning the spinning rotor, wear protection and spinning properties at the damaged places of the spinning rotor are preserved. As a result, it is possible to prevent a considerable shortening of the service life of the spinning rotor.

Abstract: The present invention is addressed to a control logic for determining the occurrence of shaft decoupling in a gas turbine engine. The control logic in the preferred embodiment receives inputs for shaft rotational speed and/or compressor pressure and uses these parameters for making a determination of shaft decoupling in fractions of a second, before serious damage to the gas turbine engine can occur. The control logic also utilizes multiple interval sampling, and sampling over multiple channels to verify any determination of shaft decoupling. Once a shaft decouple has been verified, fuel flow to the engine is cut off, thus shutting down the engine.

Abstract: Power generation equipment (10) comprises a compressor (11,12) into which finely dispersed water is directed. Air compressed by the compressor (11,12) is directed into combustion equipment (13) where it is mixed with steam and fuel before combustion takes place. The resultant combustion products pass through two turbines (14,15), the second of which (15) is a power turbine. The exhaust efflux from the power turbine (15) is then cooled to such an extent that its pressure falls to below atmospheric pressure. The carbon dioxide is removed from the efflux by means of a sequestration membrane (33) before the pressure of the efflux is raised to above atmospheric pressure by a further compressor (16) driven by the power turbine (15). The equipment (10) is very efficient and produces low levels of pollution.

Abstract: A radio frequency (RF) plasma thruster for use in electric propulsion for spacecraft. The thruster operates by heating plasma in a magnetic field, which then flows out along magnetic field lines, producing axial thrust. The present invention greatly increases the efficiency of the RF plasma thruster compared to previous thrusters of this type, while retaining the advantages of RF plasma thrusters over other types of electric and chemical propulsion systems. The present invention utilizes a lower hybrid wave for heating of the electrons, rather than electron cyclotron resonance (ECR) heating. The lower hybrid wave is used because it creates high-density plasmas and the antennas used to couple RF energy to the plasma are relatively simple to construct. This allows much better efficiency because no hot electron population is created to siphon off much of the RF power applied to the plasma.

Abstract: A method for controlling regeneration fuel supplied to an internal combustion engine operating with a lean fuel-air mixture during sequential rich mixture regeneration events of a NOx adsorber in which NOx emissions collected by the adsorber are purged to provide optimum emissions control and minimum fuel consumption. The method monitors the exhaust gases flowing out of the adsorber during the regeneration event to detect when fuel-air mixture to the engine is within an excessively lean or rich range. When the sensed exhaust gases contain an excessively lean fuel-air mixture, fuel is increased to the engine. Fuel is decreased when the sensed exhaust gases contain an excessively rich fuel-air mixture. The fuel can be increased or decreased by adjusting the duration or fuel rate of the regeneration event.

Abstract: A self-contained air conditioner cools a building's air using a water-cooled economizer coil and two refrigerant evaporators. The two evaporators are provided by two separate refrigeration circuits, each having its own water-cooled condenser. A water circuit interconnecting the economizer and the two condensers is reconfigureable to selectively operate the air conditioner in a normal mode or, if conditions permit, in an energy-saving economizer mode. In the normal mode, the water circuit conveys cooling water in series through both condensers while bypassing the economizer coil. In the economizer mode, the water flows in series through the economizer and one of the condensers while bypassing the other. The refrigerant circuit whose condenser is bypassed can thus be deactivated to save energy. The economizer coil and the condenser it bypasses have generally the same flow resistance to water flow.
