Abstract: The Modular Multifunctional Solar Structure is an innovative design in the field of Renewable Energy. This system, the schematic diagram of which is shown in figure 2, will collect the energy from the sunlight by using lightweight rotary thermal or bivalent photovoltaic solar receivers (A), sandwiched between Support Columns (B) which house the technical services.  Because of its modular concept, this structure allows: an easy and progressive assembly in places exposed to the sun, with negative angles of down to 90~;  and a microprocessor controlled solar tracking device, with alternative fixed or manually adjustable settings. These features solve the traditional problems associated with solar energy collectors, which include: a fixed position which is confined to specific angles, or a vertical layout, both of which are inefficient in terms of energy recovery; large dimensions and heavyweight collectors, which may need ungainly support structures; and wasted space.

Title: Chromatographic methods for measuring impurities in a gas sample
Inventor: FORTIER ANDRE
IPC: G01N30/46
Filed: 2006-02-22
Abstract: The present invention provides an improved chromatographic system and an improved chromatographic method for measuring impurities in a gas sample that advantageously allow to extract a peak of impurity masked by the sample background. The method extracts an impurities peak from the sample background and put it in a second sample loop. Then, this second sample loop volume is injected into a second separation column. In fact, the system takes a "slice" from the sample background and fills the second sample loop with it. Then, the "slice", whose width is advantageously substantially equal to the impurities peak width, is injected in the second separation column. In a further preferred embodiment, the method also advantageously allows to concentrate a predetermined impurity, thereby providing an improved precision on the results. The chromatographic method advantageously provides an improved measure of argon in oxygen, oxygen in argon and oxygen in hydrogen.
