Title: Multi-stage steam-power/working process for the generation of electric energy in a cycle and arrangement for carrying it out
Inventor: HARAZIM WOLFGANG
IPC: F02C1/10
Filed: 1998-12-09
Abstract: The aim of the invention is to further improve the closed cycle for generating electric power in such a way that efficiency is enhanced and general pressure and temperature requirements regarding the working fluid used are substantially reduced. The invention also seeks to provide an improved technical solution that meets the requirements of continuos operation at rated output despite fluctuations in load requirements. This is achieved through a multistep steam power operating method for generating electric power in a cycle by using an additional gaseous energy carrier to increase the pressure, the temperature and the volume of the working fluid in the cycle and by recirculating the working fluid in the cycle in such a way that continuously overheated steam is used as a working fluid. The invention can be used in the generation of electric power in a cycle.

Title: Membrane electrostatic precipitator
Inventor: BAYLESS DAVID J
IPC: B03C3/60
Filed: 1999-06-09
Abstract: A membrane (8) is used as a collection substrate in an electrostatic precipitator. Possible material choices include fibers in the form of woven mats, screens made from stainless steel wires or fiber reinforced polymer composite membranes. The membranes have a tensile bias (14) applied during operation, and have impulse tensile forces applied during a dust removal step. By combining a dry electrostatic precipitator membrane field with wet-film cleaning field, it may be possible to improve collection efficiencies both by reducing turbulence and eliminating re-entrainment losses due to rapping. Through implementation of new materials that resist hostile electrostatic precipitator environments, the invention enhances the possibility of using novel technologies, such as pulsed corona and others, suitable for removal of molecules such as nitrogen oxides and sulphur oxides, which is very important for meeting the proposed PM2.5 EPA emissions regulations.

Abstract: A circuit having a full bridge configuration with a single actively biased switching element. In one embodiment, the circuit is a ballast circuit havin g a full bridge inverter with one switching element. The bridge includes a dio de coupled to the switching element such that the diode and the switching eleme nt are coupled between positive and negative rails of the inverter. The bridge further includes first and second capacitors coupled end to end across the positive and negative rails. The ballast circuit can be coupled to a rectifier/boost circuit having a boost inductor coupled to the inverter circuit. In an exemplary embodiment, a ballast circuit includes an inverter circuit having a switching element with a conduction state controlled by a control circuit which limits a voltage applied to the lamp. The control circuit provides a conduction control signal to a duty cycle control circuit . The conduction control signal alternately biases the switching element to conductive and non-conductive states at a first duty cycle when the lamp voltage is below a predetermined level. When the lamp voltage becomes greate r than the predetermined level, the duty cycle control circuit decreases the switching element to a second duty cycle, which is less than the first duty cycle, to reduce the voltage at the lamp.
