Title
(EN) METHOD FOR COMPRESSING GASEOUS MATERIALS IN A CONTAINED VOLUME
(FR) PROCEDE DE COMPRESSION DE MATERIAUX GAZEUX DANS UN VOLUME FERME
Abstract
(EN)
A method for compressing gases in a contained volume consisting of hollow glass microspheres (17). The gases are compressed under high pressure and can be easily handled and stored. The gases to be compressed and contained in the microspheres (17) are used as blowing gases (10) to blow the microspheres. The hollow glass microspheres (17) are made by forming a liquid film (12) of molten glass across a coaxial blowing nozzle, applying the blowing gas (10) at pressure on the inner surface of the glass film to blow the film and form an elongated cylinder shaped liquid film (12) of molten glass. A transverse jet (13) is used to direct an entraining fluid (14) over and around the blowing nozzle (5) at an angle to the axis of the blowing nozzle. The entraining fluid (14) as it passes over and around the blowing nozzle (5) fluid dynamically induces a pulsating or fluctuating pressure field at the opposite or lee side of the blowing nozzle in the wake or shadow of the coaxial blowing nozzle to form into a spherical shape (17).

Un procede de compression de gaz dans un volume ferme se composant de microspheres en verre creuses (17) est decrit. Les gaz sont comprimes sous haute pression et peuvent etre facilement manipules et stockes. Les gaz a comprimer et contenus dans les microspheres (17) sont utilises comme gaz de soufflage (10) pour le soufflage des microspheres. Les microspheres creuses en verre (17) sont preparees en formant un film liquide (12) de verre fondu au travers d"un ajutage coaxial de soufflage, en appliquant le gaz de soufflage (10) sous une pression positive sur la surface interne du film de verre afin de souffler le film et former le film liquide en une forme de cylindre allonge (12) en verre fondu. Un jet transversal (13) est utilise pour diriger un fluide d"entrainement par dessus et autour de l"ajutage de soufflage (5) angulairement par rapport a l"axe de l"ajutage. Le fluide d"entrainement (14), pendant qu"il passe par dessus et autour du fluide de l"ajutage de soufflage (5), induit de maniere dynamique un champ de pression a impulsions ou fluctuant a l"oppose, ou cote sous le vent, de l"ajutage de soufflage dans le sillage ou l"ombre de cet ajutage coaxial de soufflage afin d"obtenir une forme spherique (17).
