摘要:
The invention relates to an object made of hollow glass and having, for a thickness of 5 mm, a global light transmission higher than or equal to 70%, said global light transmission being calculated by taking into account the illuminant C as defined by standard ISO/CIE 10526 and the colorimetric reference observer C. I. E. 1931 as defined by standard ISO/CIE 10527, and a filtration power higher than or equal to 65% and preferably 70%, said filtration power being defined as equal to a value of 100% minus the arithmetic average of transmission of 330 to 450 nm, wherein said object has a silico-sodo-calcic chemical composition that comprises the following optical absorbing agents in a concentration that varies within the following weight limits: Fe 2 O 3 (total iron) 0.01 to 0.15% TiO 2 0.5 to 3% Sulphides (S 2- ) 0.0010 to 0.0050%.

The invention relates to a combustion process, especially for melting glass, in which a flame is created both by an impulse of liquid fuel and a single impulse of gaseous fuel, characterized in that the fraction of the total power due to the liquid fuel varies between 20 and 80%, and in that the specific impulse of the gaseous fuel is limited to a sufficiently low value such that the NOx content of the fumes produced does not exceed 800 mg/Nm3 for a cross-fired furnace and 600 mg/Nm3 for an end-fired furnace; an injector for implementing this process; a burner comprising one or more such injectors; a furnace comprising at least one such burner.

The invention relates to a method for making red copper glass that comprises the following steps : providing a mass of sulphide-free, colourless molten glass having a mass iron-oxide content of between 0.01 an 0.15 %; feeding said mass of molten glass into a dispensing channel in which copper oxide and tin oxide are added to said mass of molten glass, the partial pressure of oxygen in said mass of molten glass ranging from 10-7 to 10-4; forming glass objects such as bottles or vials from said mass of molten glass, and heat-treating said glass objects to develop a red colour.

The invention relates to a method for producing bulk hollow glass articles that, positioned next to the others with the same orientation on the same plane, are capable of coming in mutual contact along a surface of revolution, characterized in that after they exit the tunnel lehr, they are set in rotation on one turn at least along the axis of the surface of revolution, the latter being covered by an additional layer that reduces the coefficient of friction by a method with solid contact. The invention also relates to a hollow glass article obtained by said method, and to an assembly for packaging these articles.

The invention concerns an installation for making at least two products of different dimension and/or configuration in moldable thermoplastic materials, in particular glass, comprising: a machine (IS) including a number between 2 and 20 of individual sections (SA, SB), each section including an equal number of blank mold(s) (12) and blow mold(s) (13); a system feeding (1) said machine (IS), at each cycle, with at least two parisons (3a, 3b), wherein the number of parisons delivered by the feeding system is higher than the number of blank or blow mold(s) included in an individual section of the machine (IS). The invention also concerns the related product.
摘要:
La présente invention concerne un procédé de formage d'un objet en verre creux muni d'une bague et d'une épaule, utilisant une technique « soufflé-soufflé » comprenant une phase d'ébauchage, une phase de transfert et une phase de finition. Selon l'invention, lors de la phase de finition, on réalise un enfoncement de la bague dans l'épaule tout en maintenant au moins une partie de la hauteur de la bague.
un produit verrier comportant un corps et une bague, au moins une partie de ce corps et cette bague définissant deux axes non parallèles ; un procédé et une machine I.S. pour fabriquer ce produit.
Ce procédé comprend les étapes consistant à :
introduire une paraison (3) de matière fondue dans la cavité (2) d'un moule ébaucheur (1), dont au moins une section (4) d'entrée de la paraison est sensiblement verticale ; laisser la matière fondue pénétrer dans le fond du moule ébaucheur ; percer la bague (13) par translation d'un poinçon (7) selon un axe (8) non vertical ; retourner l'ébauche par rotation de 180° par rapport à un axe horizontal et le transférer dans un moule finisseur (14) ; et effectuer un soufflage par la bague (13) afin de conférer au produit sa forme finale.

L'invention a pour objet un procédé de filtration des poussières dans les effluents gazeux provenant d'un four verrier, procédé qui comprend les étapes suivantes :
→ on filtre les effluents à une vitesse de traversée d'au moins 0,1 m/s à l'aide d'au moins un média filtrant en aval du four, → on régénère le média filtrant par lavage à l'aide d'un solvant, notamment à base d'eau, apte à dissoudre et/ou drainer la majorité des poussières filtrées.
