Patent CA-2414709-A1 (CA)
Inventor: KIURU ERKKI SAKARI
IPC: G01T1/29
Filed: 2002-12-18
Abstract: The invention relates to a radiation detector, an arrangement and a method for an energy-dispersive detection of X-ray photons. X-ray photons are allowed to collide (701) in the radiation detector (201, 601), whereby there are produced (702, 703, 704, 705, 706, 707, 708) observations of the X-rays photons that collided in the detector. According to the invention, there are separately produced observations of X-ray photons (702, 703, 704) that collided in the first detector space (205, 501) of the radiation detector and X-ray photons (705, 706, 707, 708) that collided in the second detector space (206, 502) of the radiation detector. The (712) observations of X-ray photons that collided in the first detector space (205, 501) are ignored, when there is received a simultaneous observation of an X-ray photons that collided in the second detector space.

Abstract: A compact fused silica, electroded HID lamp for automotive forward lighting, which contains no mercury. The lamps voltage, approximately 40 volts, is developed in this lamp by vaporizing zinc iodide instead of mercury. A compromise between voltage and luminous flux is achieved through the choice of the sodium scandium (Na:Sc) molar ratio, between 4.5:1 and 6:1 and a zinc iodide (ZnI2) dose of 2 to 6 micrograms per cubic millimeter that permits the lamp to operate within the North America, European and Japanese automotive color specifications for white light. The voltage in the lamp can be controlled according to the zinc iodide doping level without seriously impacting the visible spectrum otherwise provided by the other known dopants in the lamp.

Abstract: Séparateur de batterie destiné à être placé entre les plaques conductrices à l'intérieur d'une batterie; il comprend une natte de fibres, non tissée et faite d'une ou plusieurs fibres non tissées qui ont une forme spécifique en coupe transversale et manifestent une action microcapillaire. De préférence, les fibres sont faites d'un thermoplastique sélectionné dans le groupe constitué de polyoléfines, fluoropolymères, polyimides, polysulfones, polyesters, polyamides et leurs mélanges. Chacune des fibres comprend une surface externe, une cavité interne creuse et une fente allongée. La cavité interne creuse communique avec la surface externe au moyen de la fente allongée. Les forces capillaires à l'intérieur de la fibre sont supérieures à celles agissant à la surface de la fibre, ce qui permet à un électrolyte liquide de se déplacer facilement à l'intérieur de la fibre par effet de mèche. De ce fait, le séparateur de batterie tend à diriger le liquide vers les plaques de batterie adjacentes même si un niveau d'électrolyte, à l'intérieur de la batterie, baisse en dessous des sommets des plaques.

Title: Spinning disc aerator
Inventor: ARMSTRONG RICHARD JAMES
IPC: B01F27/93
Filed: 2003-10-02
Abstract: The spinning disc aerator is a motor driven device for effectively dispersing air into a pool of water with high energy efficiency. A vertical cylindrical duct is suspended by a float with its lower end in the water and supports a drive motor on its upper end above the water surface. A drive shaft is directly coupled to the motor and extends axially through the duct to terminate in a flat circular disc close to the immersed end of the duct forming a thin annular nozzle therebetween. Upon being spun by the motor the disc draws air down the duct and out through the nozzle in the form of a thin air sheet having maximized surface area exposed to the pool water. Driven into the water by the spinning disc, the air sheet eventually breaks up into fine bubbles which are carried far into the pool by the swirling flow of water from the disc.
