Abstract: Un joint de rail sert à combler l'espace entre un rail et un matériau de surface avoisinant dans un croisement de rail ou une construction de voie, où le joint de rail peut être retiré de l'espace et être réinstallé dans l'espace sans endommager le matériau de surface avoisinant. Plus particulièrement, le joint de rail est formé au moyen dun élément à charnière intégral qui comporte une position fermée et une position ouverte où une portion supérieure du joint de rail est dégagée et se prolonge vers le haut en s'éloignant dune portion inférieure du corps de joint et donne une souplesse supplémentaire au corps de joint. Pour retirer le joint de rail de l'espace adjacent au rail, le joint de rail peut être manipulé de sorte à être retiré de l'espace. Pour réinstaller le joint de rail, la souplesse supplémentaire fournie par l'élément à charnière permet au joint de rail dêtre manipulé et déformé au besoin de sorte à être réinstallé dans l'espace ouvert. Le joint de rail peut aussi être formé, au moyen de creux d'ancrage, à des extrémités opposées du corps de joint de rail afin de recevoir des clés dancrage qui aident à fixer le joint de rail à lintérieur de l'espace et empêcher le mouvement longitudinal et le déplacement du joint de rail avec le temps.

In a first stage (2) a pure or almost pure stream of acidic contaminants is separated from the feedstream, the acidic contaminants (4) stream suitably containing less than 5 vol% of hydrocarbons. The remaining stream (3) comprises the hydrocarbons and still a certain amount of gaseous acidic contaminants. In a second stage (5) a pure or almost pure stream of hydrocarbons (8) is separated from the remaining stream, where after the then remaining stream (6) is combined with the feed for the first stage (1), the hydrocarbon stream suitably containing less than 5 vol%  of acidic contaminants.

Abstract: Organic matter, i.e., biomass, fibrous plant matter, organic chemicals or organic waste, or other carbon-based matter is converted to synthesis fuel gas by reactive contact with superheated steam at a temperature of about 200 to 2000 degrees C, typically 500 to 1700 degrees. A reactor (10) has a generally tubular envelope (12), a rotor (14) within the envelope, and hot reaction spaces (30, 42) disposed annularly within the wall of the tubular envelope. The steam and biomass particles can be heated to the required temperatures using RF induction coil (34) and susceptors (32, 44). The product gases include H2, CO, and CO2 in ratios controlled by a programmable controller (55). Control of temperature, biomass feed rate and water flow preselects the output synthesis gas mix. The synthesis gas may be processed into portable liquid fuels, or can be used directly in a fuel cell.

Title: A system comprising the gasification of fossil fuels to process unconventional oil sources
Inventor: TSANGARIS ANDREAS
IPC: C10C3/00
Filed: 2008-05-12
Abstract: A facility comprising integrated systems for the extraction, and optionally upgrading and/or refinement, of unconventional oil sources, using fossil fuels as a primary source of energy. In particular, this facility provides a means to gasify one or more fossil fuels in an efficient manner, converting it into intermediate products such as heat, steam and electricity, which are then used by the system to obtain useful fuel products from unconventional oil sources such as tar sands and oil shale. The design of the components of this facility is optimized such that the overall costs are competitive with an equivalent unconventional oil source processing facility that uses natural gas as a source of processing energy.  The facility can be used on its own, may use supplemental natural gas energy sources, or may be used in conjunction with an existing facility that uses natural gas as an energy source in order to improve the overall cost effectiveness of the processing and/or reduce the requirement for other energy sources, such as natural gas.

Abstract: A high-resolution digital seismic and gravity sensor includes an inertial mass connected to one or more force-sensitive resonators. The weight of the inertial mass is substantially unloaded with a spring arrangement when exposed to the force of the static gravity field. Seismic accelerations applied to the base of the seismic and gravity sensor, or changes in the gravitational field, generate loads that are transmitted to force-sensitive resonators so that changes in resonant frequency are related to the applied load. The changes in resonant frequency are thus a measure of the seismic accelerations and gravitational field variations.
