Patent CA-2511607-C (CA)
Title: Lighting system used for heating
Inventor: DUBOIS SERGE
IPC: F24F13/078
Filed: 2005-07-15
Granted: 2011-12-20
Abstract: The invention relates to a heating system fed by light itself, wherein a housing containing at least one light is provided with two (2) functions: the internal part thereof is used for capturing heat and the external part is used for dispersing heat though its various surfaces, thereby heating the ambient air The heat energy dispersed by the lamp(s) is used for heating. Said system is advantageously characterized in that it is cost saving since the only expense relates to lighting and a fan, if any to disperse the heat. The invention makes it possible to avoid the use of highly heat-consuming heating elements and to reduce the costs. This box can be installed on an existing lighting system, such as the ceiling with air intakes at floor level and with a fan that draws cool air blowing on the ground and the air is warmed by the housing before emerging as heated air. The air intake can also be provided with a filter to collect dust. This box can be wall mounted or integrated into a structure, for example within a floor. This system can be fixed or mobile and be designed according to needs, tastes, physical setting, desired effect and design desired. It is also possible to connect several housings using a conduit. The lamp housing is designed using metal or heat-conductive materials thereby making it possible to recover the heat from the lighting system. The aim of said invention is to reduce costs of heating by using light for more than just lighting.

Abstract: A planar optical platform for generating a Raman signal from a foreign object comprises an input region and an output region, for receiving and extracting optical radiation, optically coupled to a plasmonic band structure region. The plasmonic band structure region comprises a layer of a first material, having a first refractive index, patterned with an array of sub-regions of a second material, having a second refractive index, wherein a side-wall of each sub-region is coated with a metallodielectric layer. The array of sub-regions gives rise to a plasmonic band structure and, in use, each sub-region confines a plasmon resonance excited by optical radiation coupled into the plasmonic band structure region, which gives rise to a Raman signal from a foreign object placed proximate the plasmonic band structure region. The platform may be incorporated into a spectroscopic measurement system and is particularly useful for surface-enhanced Raman spectroscopy of analyte molecules.

Granted: 2010-06-01
Abstract: This invention relates to oil and gas industry, more specifically, to the improvement of the hydraulic permeability of sand pumped into the fracture during formation hydraulic fracturing in the process of oil production. The positive result planned to be achieved by using the new proppant material is almost complete prevention of sand backflow, a significant increase in sand packing permeability and prevention of the production of fine grained proppant. This result is achieved due to the proppant material in the form of rigid elastic particles in the form of plates having a maximum to minimum dimension ratio of more than 5 made from a corrosion resistant material. The plates should not be deformable. The thickness of the particles can be 100 to 300 µm. The method of hydraulic fracturing wherein at least part of the fracture is filled with the proppant material in the form of rigid elastic plates or gratings having a maximum to minimum dimension ratio of more than 5 preferably made from stainless steel or low-carbon steel provides for the claimed positive result. The rest of the fracture can be filled with standard nonmetallic proppant/sand. The permeability of the fracture is thereby improved.

Title: Exerciseur de poignet avec force de demarrage auxiliaire
Inventor: CHUANG YUN YU
IPC: A63B21/22
Filed: 2007-06-20
Granted: 2013-12-03
Abstract: Exerciseur de poignet comprenant un élément de coffrage supérieur et un élément de coffrage inférieur fixés l'un à l'autre pour entourer un rotor. L'élément de coffrage supérieur comporte une ouverture supérieure qui expose une partie du rotor. Le rotor est doté de parois opposées sur lesquelles deux essieux opposés sont fixés respectivement. Les essieux sont raccordés de façon rotative à une bague externe. La bague externe comprend un appareil de résilience. La paroi du rotor qui fait face à l'appareil de résilience est dotée d'un mécanisme d'accroche mobile qui est raccordé à l'appareil de résilience de façon amovible, sélective et fonctionnelle. Ainsi, lorsque le rotor est mis en rotation initialement ou est tracté pour effectuer un mouvement linéaire en étant mis en contact avec une surface d'appareil, le dispositif de résilience augmente la force du ressort de compression qui, une fois le rotor libéré, fait en sorte que le rotor tourne en direction inverse et gagne une force de démarrage auxiliaire ainsi qu'une vitesse de rotation initiale. De plus, le mécanisme d'accroche mobile peut être désenclenché de l'appareil de résilience par une force centrifuge agissant sur lui et induit par une rotation haute vitesse du rotor, de façon à permettre le fonctionnement régulier de l'exerciseur de poignet.
