Title: Apparatus for rapid, high volume production of solid co2 pellets
Inventor: ELIAS MARC C
IPC: C01B32/55
Filed: 2002-10-01
Abstract: A lightweight, highly mobile and efficient apparatus (34) for instantaneously producing a high volume of solid carbon dioxide (CO2) pellets. The apparatus utilizes liquid CO2 that is discharged and expanded through a nozzle or nozzles and expanded to reach a triple point condition where liquid, gaseous and solid phases can coexist and flash to a mixture of CO2 in a gaseous phase and particles of snow by a process well known in the art. The gaseous CO2 (80) is discharged into the atmosphere or recovered for converting back to liquid. The snow particles are aggregated into larger flakes and compressed into pellets in a compression structure by a rotor (82) with radially movable blades (90) forming variable volume pockets (92) associated with the interior of a housing to compress the flakes into pellets. The pellets may be discharged from the housing into an airlock which includes a rotor (118) to convey the pellets to an air discharge (142) that is isolated from the compression structure to facilitate conveyance of the pellets to a point of use, such as the site of a fire in order to extinguish the fire.

Abstract: L'invention concerne des dalles de moquette pouvant être disposées les unes à côté des autres sur la surface d'un sol pour créer une impression de la lumière provenant du sol ou une illusion de profondeur. Le revêtement de sol possédant les propriétés de cette invention est obtenu à l'aide d'un procédé consistant à produire des modules de revêtement rectilignes sur lesquels sont réparties des couleurs allant du très foncé au très clair, d'un bord à l'autre de la dalle. Des touffes de fibres fournissent un <= arrière-plan >= de couleur et d'intensité constantes le long de la plus grande dimension de la dalle, allant du très foncé au très clair, d'un côté à l'autre de la dalle. Entre le bord foncé et le bord clair de la dalle, il existe une zone intermédiaire comprenant un dégradé de couleurs allant du plus foncé au plus clair. L'intensité des couleurs dans la zone intermédiaire passe de préférence du clair à une intensité relativement moyenne entre le bord foncé et le bord clair de la dalle, de façon que l'intensité du bord de couleur claire de la dalle soit supérieure et que la couleur claire soit ainsi plus dominante que sa couleur adjacente sur la dalle de moquette. Ces caractéristiques permettent d'obtenir des couleurs claires dans les bords qui <= ressortent >= sur les dalles demoquette, ce qui accentue l'illusion créée par l'invention, en particulier lorsque les bords de couleur claire sont disposés à côté de bords de couleur foncée.
