Disclosed herein are combustion systems, power plants, and flue gas treatment systems that incorporate sweep-based membrane separation units to remove carbon dioxide from combustion gases. In its most basic embodiment, the invention is a combustion system that includes three discrete units: a combustion unit, a carbon dioxide capture unit, and a sweep-based membrane separation unit. In a preferred embodiment, the invention is a power plant including a combustion unit, a power generation system, a carbon dioxide capture unit, and a sweep-based membrane separation unit. In yet another embodiment, the invention is a flue gas treatment system that incorporates three membrane separation units with a carbon dioxide liquefaction unit.

Tensioning device (1) for a traction element drive, such as a belt or chain drive, with a tensioning arm (4), which can pivot relative to a body (2) about a pivot axle (3) and on whose distal end a roller (5) supported rotatably is arranged for tensioning the traction element, for the purpose of which there is a torsion spring (6) acting between the pivot axle (3) of the tensioning arm (4) and the body (2), and the pivot axle (3) is supported so that it can slide by at least one radial-bearing arrangement (7) and at least one axial-bearing arrangement (8), wherein the axial-bearing arrangement (8) comprises a friction disk (9) arranged concentric to the pivot axle (3), wherein the friction disk (9) has an axial stop surface (11), which comprises at least one radial circumferential key groove (12) and that at least one radial circumferential friction spring, which extends into the key groove (12), is constructed in the surface adjacent to the stop surface (11) of the friction disk (9).
摘要:
A tensioning device for a traction mechanism drive for a belt drive that is incorporated in an internal combustion engine, in order to drive components of the engine or installed accessories. The tensioning device has a construction that is advantageous under production and construction viewpoints, by a high degree of robustness, and also by an advantageous mechanical operating behavior. The tensioning device includes a base part, a swivel arm, a torsion spring with a first winding end section that is allocated to the swivel arm and a second winding section that is allocated to the base part for applying a pivoting moment acting between the base part and the swivel arm and forcing the swivel arm in a tensioning direction, and a damping device for generating a damping force that counteracts a pivoting of the swivel arm directed against the tensioning direction. This damping device includes a first friction surface element that is arranged in a region of the winding end section of the torsion spring allocated to the swivel arm, and forms a friction surface that is used for applying friction force and that sits on a counter friction surface. In the region of the second winding end of the torsion spring for the base part, there is a second friction surface element that forms a friction surface that sits on a counter friction surface, and the counter friction surface is formed by a friction surface structure that can pivot together with the swivel arm.

摘要:
A method for intrusion detection in an optical fiber communication network. The method includes at a first location on an optical fiber segment, receiving a set of multiple optical signals having wavelengths differing from each other, measuring received signal power for each of the received multiple optical signals, and repeating the receiving and the measuring steps. Each optical signal in the repeated steps has same wavelength as corresponding received optical signal in the initial steps. The method further includes computing a signal power loss between each received optical signal in the repeated set and the corresponding optical signal in the initial set, fitting a curve of signal power loss vs. wavelength to the computed signal power losses using a statistical analysis, and if the signal power loss of the curve over a preselected wavelength band is at least as great as a preselected minimum loss level, providing intrusion notification.

Known techniques to improve metal-oxide-semiconductor field effect transistor (MOSFET) performance is to add a high stress dielectric layer to the MOSFET. The high stress dielectric layer introduces stress in the MOSFET that causes electron mobility drive current to increase. This technique increases process complexity, however, and can degrade PMOS performance. Embodiments of the present invention create dislocation loops in the MOSFET substrate to introduce stress and implants nitrogen in the substrate to control the growth of the dislocation loops so that the stress remains beneath the channel of the MOSFET.

The present invention includes aspects of a designer program or tool for customizing a clinical trial program to a particular protocol of a particular clinical trial. The designer program includes visual cues or mechanisms for organizing trial components within the designer program in a straightforward manner such that technically low skilled designers can implement often complex trial protocols. In an embodiment, the designer program includes validation scripts that test functions, derivations, queries and the like. Moreover, use of the designer program can include development of trial libraries that can make customizations reusable, scalable, and highly efficient.

A retractable shade finding particular use in covering non-linearly aligned architectural openings or curved openings, includes one continuous curtain following a predetermined path along the openings. A segmented drive system forms linear segments of a drive system which in combination are adjustable to accommodate various curvatures of openings or angles between adjacent architectural openings. Movement of the shade between retracted and extended positions is automatically stopped and a fail-safe system is provided to prevent inadvertent extension of the shade such as when the shade is used to cover the windshield of a recreational vehicle or the like.
