Abstract: Divulgation d'une méthode et d'un appareil pour convertir des déchets gazeux provenant de procédés industriels, comme le raffinage du pétrole ou la production de noir de carbone, de coke, d'ammoniac ou de méthanol, en produits utiles. Cette méthode consiste à introduire les déchets gazeux dans un bioréacteur où ils subissent une fermentation pour donner divers produits, tels que des acides organiques, des alcools, H2, des SCP, et des sels d'acides organiques, sous l'action de bactéries anaérobies dans le bioréacteur. Ces produits précieux sont ensuite récupérés, séparés et purifiés.

Title: Optical systems with one or more stabilised laser signal sources
Inventor: BOOT ADRIAAN JOHAN
IPC: H04B10/572
Filed: 1997-11-21
Granted: 2002-01-29
Abstract: Optical stabilisation system having a signal source (1) connected to a transmission line (2) and a noise source (3). The signal source (1) comprises a laser having a number of laser modes within a first wavelength band for generating an optical transmission signal (S). The noise source generates a narrow-band noise signal which is inserted into the transmission line via coupling means (5) and is injected into the laser of the signal source (1). The noise signal forces the laser to operate in a laser mode within the noise band. Via a power distributor (11), a portion of the noise signal can also be injected into a laser of a further signal source (9) for stabilisation in a laser mode within the same noise band. Any signals outside the noise band are removed from the transmission signal by a narrow-band filter (8). The stabilisation system is applied in passive optical networks for groupwise wavelength assignment to network terminals.

Title: Endovascular graft for repairing abdominal aortic aneurysms
Inventor: KONSTANTINOS PAPAZOGLOU O
IPC: A61F2/848
Filed: 1998-04-09
Granted: 2009-10-13
Abstract: This is regarding a type of device aimed at a simpler, in relation to already existing techniques, endovascular positioning of a stent-graft in the abdominal aorta for the therapy of aneurysms up to the point of its bifurcation.  This device is comprised of a system of three cylinders: a "main" centrally placed and two "limbs" peripherally placed. Each of these cylinders has a central and a peripheral orifice. The cylinders are comprised of a cylindrical metallic skeleton which is self-expanding and made out of stainless steel or nitinol and which is externally covered with a cylinder made out of thin-layered PTFE, Dacron or some other elastic biocompatible material, refolded around the peripheral orifice of the skeleton of the main cylinder. These cylinders can be compressed into small diameter tubules and enter the vascular lumen.  After their insertion into the desired position, they expand, regaining their original diameter. The main cylinder is placed inside the aorta becoming more circular when it comes in contact with the healthy part of the aorta central to the aneurysm at the center of the orifice. The peripheral orifice of the main cylinder sits upon the expanded aortic bifurcation. The two limbs have a central orifice with a diameter equal to or approximately about 2 mm smaller than the diameter of the peripheral orifice of the main cylinder. The branching of the main cylinder is accomplished by the entrance of the main ends of the two limbs inside the peripheral end of the main cylinder. Both limbs are at the same height in such a manner that they compress each other at the center of the cylinder. Each limb exerts equal pressure, whereas equal pressure is also exerted on the internal surface of the main cylinder from their external surface and together they both occupy at the height of their orifices the entire perimeter of the main cylinder. Alternatively, as limbs (peripheral cylinders), tubes of different diameters and types of skeletons can be used.

Abstract: L'invention concerne une structure de bogie comprenant au moins deux essieux rigides (1a-1c) qui sont reliés par un levier basculant (10a, 10b). Le levier basculant pivote en son centre de telle façon qu'il puisse se déplacer dans sa direction longitudinale suite à des mouvements de direction. Le levier basculant est, de préférence, relié à l'essieu de bogie qui tourne au moins à l'aide d'un joint d'une corne (13), et ainsi cet essieu détermine le déplacement longitudinal du levier basculant. Le levier basculant est relié aux autres essieux qui tournent plus à l'aide de barres de suspension (8a, 8b). Selon un mode de réalisation préféré de l'invention, on utilise une barre de suspension pivotant sous l'essieu et ainsi la barre de suspension s'incline moins en relation avec un mouvement longitudinal du levier basculant.

Patent CA-2340123-C (CA)
Inventor: WOBBEN ALOYS
IPC: H02M7/48
Filed: 1999-09-07
Granted: 2004-05-11
Abstract: The invention concerns an inverter for feeding sinusoidal currents into an ac network. The object of the present invention is to improve the ability to withstand short-circuits and to reduce the danger of a short-circuit. The invention is based on the realisation of using only a single switching unit for producing a half-oscillation of a sinusoidal oscillation. Thus, for producing a positive half-oscillation of a sinusoidal oscillation, a different switching unit is used than for producing the negative part of the sinusoidal current. The consequence of this is that only one switch of a switching unit is cycled or actuated during the production of a positive half-oscillation and another switch during the production of the negative half-oscillation of a sinusoidal current. The risk of a short-circuit between the two switches is thus reduced to the time during the change from the positive to the negative or from the negative to the positive half-oscillation respectively.
