English

Subject field(s)
  • Plastics Manufacturing
OBS

E. I. du Pont de Nemours & Co. has developed a novel approach to gain some of the advantages of a coextruded blow-molded bottle without the cost and complexity of multiple extruders and expensive scrap reclaim systems. Only minor modification of the basic equipment is required. A barrier resin is tailored for physical blending with a base resin in much the same way that colorant is blended with a resin. However, instead of producing a homogenized mix, the barrier resin is permitted to laminate in the base resin. Several random multiple layers of barrier resin of various lengths and sizes are created. Although no single layer completely covers the entire shape and surface of the bottle, barrier is created by the "tortuous path" the permeating gas must follow. A modified nylon material is the first to be used for this approach. Applications include fuel tanks and bottles for agricultural chemicals, thinners, and solvents.

French

Domaine(s)
  • Plasturgie
OBS

C'est pourquoi la résine barrière est placée en sandwich entre deux couches de polymère hydrophobe, c'est-à-dire qui repousse l'humidité.

OBS

[...] les couches fonctionnelles forment elles-mêmes une structure multicouche comprenant une couche de résine barrière emprisonnée entre deux couches de résine adhésive.

Record 3 - external organization data 2004-10-26

English

Subject field(s)
  • Types of Constructed Works
  • Waste Management
  • Nuclear Waste Materials
  • Compartment - Canadian Nuclear Safety Commission
CONT

These activities include the management of low and intermediate level waste at the facility, the construction of additional low and intermediate level waste storage containers/structures of the type in use at the facility, the construction of the used fuel dry storage facility, and modification of the waste volume reduction building, including the replacement of the incinerator.

French

Domaine(s)
  • Types de constructions
  • Gestion des déchets
  • Déchets nucléaires
  • Tiroir - Commission canadienne de sûreté nucléaire
CONT

On compte au nombre de ces activités la gestion des déchets faiblement et moyennement radioactifs à l'installation, la construction d'autres structures ou conteneurs du type déjà utilisé à l'installation pour le stockage des déchets faiblement et moyennement radioactifs, la construction de l'installation de stockage à sec du combustible irradié ainsi que la modification du bâtiment de réduction du volume des déchets, y compris le remplacement de l'incinérateur.

Record 4 2000-05-30

English

Subject field(s)
  • Oil Production
DEF

A variation of the forward in situ combustion process where water in moderate amounts is injected simultaneously with the air.

CONT

Wet combustion : this method... is a modification of the forward combustion process with the variation that water is injected with the air. The injection of water significantly increases the heat-transport capacity of the fluids passing through the burned-out region... The injection of water also quenches the trailing edge of the combustion zone before all the fuel is consumed, thereby enabling a more rapid movement of the combustion zone through the reservoir.

French

Domaine(s)
  • Production pétrolière
DEF

Combustion à co-courant combinée à une injection d'eau qui, par sa vaporisation, permet un transfert de chaleur et de pression d'amont en aval du front de combustion.

CONT

Combustion à co-courant combinée à l'injection d'eau (combustion «humide») [...] Aussi, peut-on injecter de l'eau en même temps que l'air après le démarrage du processus de combustion [...]

OBS

L'intérêt de ce procédé est l'utilisation du pouvoir caloporteur élevé de l'eau pour prélever l'enthalpie accumulée derrière le front de combustion et la transporter en aval de celui-ci.

Record 5 1990-03-13

English

Subject field(s)
  • Aeroindustry
CONT

Further avionics options now being considered for an aircraft modernisation program include a new autopilot, improvements to the radar and electro-optical viewing system(EVS) largely to do with maintainability, a new fuel gauging system and modification of the ALQ-117 ECM system including phased-array aerials, greater power and polarisation diversity designed to defeat Soviet monopulse radar.

French

Domaine(s)
  • Constructions aéronautiques
CONT

Parmi d'autres équipements électroniques de bord, envisagés dans le cadre d'un programme de modernisation de l'avion, figurent un nouveau pilote automatique, des versions améliorées du système de vision électro-optique [...] et du radar, un nouvel ensemble de jauges de carburant et une version modifiée du système de CME ALQ-117 avec aérien à réseau en phase, plus puissant, à diversité de polarisation, conçue pour faire échec aux radars monopulsés soviétiques.
