Record 1 2015-04-09

English

Subject field(s)
  • Plastics Manufacturing
DEF

A pressureless moulding process in which dry, fusible powders are caused to fuse into a uniform layer against a mould wall.

CONT

Powder molding.... The metal part is usually coated in a two component tank in which the powdered resin held in place by a porous plate is mixed with a highly-compressed gas which is forced through the porous metal plate. The gas-powder mixture, which resembles a fluid, adheres to any metal part, which, after being preheated above the melting point of the resin, is placed in the fluidized bed atmosphere.... The final fusing of the polymer takes place in an oven or in a bath of molten salt.

OBS

powder moulding: term and definition standardized by ISO.

DEF

Procédé de moulage sans pression, selon lesquel des poudres sèches fusibles sont amenées au point de fusion pour former une couche d'épaisseur régulière contre la paroi d'un moule.

moulage à partir de poudres : terme et définition normalisés par l'ISO.

Spanish

Campo(s) temático(s)
  • Fabricación de plásticos
DEF

Proceso de moldeo sin presión en el cual se funden polvos secos fusibles para formar una capa uniforme contra la pared de un molde.

Subject field(s)
  • Weather Stations and Meteorological Instruments and Equipment
CONT

The Bellani plate [used to measure evaporation] consists of a thin, porous, black ceramic disk, 7. 5 cm in diameter, fused to the large end of a glazed, ceramic funnel. Water is conducted through the lower open end of the funnel from a burette which acts as a reservoir and a measuring device.

CONT

Use of Bellani plate evaporimeters for estimation of PET [potential evapotranspiration].

OBS

Evaporimeter(atmometer) An evaporimeter consists of a flat, porous ceramic disk(Bellani plate) in which water is drawn up by capillary action as water is evaporated from the disk. It is used to directly estimate crop evapotranspiration rate. Several commercial models can be easily installed near the edge of a field or on a roadway in a field.(The unit must be located far enough into the field to avoid field boundary effects.) One commercial model provides a green canvas-like material covering the ceramic disc to simulate crop leaf color. Reasonably good correlation has been found between field measurements and that calculated from Penman-type equations. Small difference in evaporation rates may be found between individual meters. Maintaining water levels and removal for freeze protection are necessary.

DEF

Appareil de mesure de l'eau évaporée, dont le capteur est un disque de porcelaine noircie, d'environ 7,5 centimètres de diamètre et quelques millimètres d'épaisseur, placé horizontalement au sommet d'une cheminée en verre alimentée en eau, sous pression, par un réservoir gradué qui permet la mesure de l'évaporation.

CONT

Il est très difficile de mesurer l'évaporation dans la nature, ou plus exactement l'évapotranspiration, puisqu'il faut tenir compte de la transpiration des plantes. [...] Suivant les pays et les besoins, la mesure est faite avec des dispositifs différents. Citons le bac à évaporation du bureau météorologique des États-Unis [...] le lysimètre, [...] l'évaporomètre Piche, employé en France surtout, [...]; enfin l'atmomètre de Bellani, utilisé dans les stations agricoles du Canada, petite assiette poreuse noire, maintenue humide et placée à quatre pieds au-dessus du sol.

CONT

La plaque de Bellani [utilisée pour mesurer l'évaporation] consiste en un disque de céramique [...] qui est joint à la grande ouverture d'un entonnoir de céramique vitrifié. L'eau est amenée à l'ouverture inférieur de l'entonnoir au moyen d'une burette qui sert en même temps de réservoir et d'appareil de mesure.

CONT

In the flat membrane module a plane membrane sheet is supported by a porous rigid plate through which the permeate can drain.

Domaine(s)
  • Techniques industrielles
  • Industrie de l'alimentation
DEF

Module constitué d'une succession de plaques porte-membranes, avec une membrane de chaque côté, et de plaques séparatrices serrées entre les plateaux d'une presse.

OBS

Les modules plan sont pour avantages leur facilité d'entretien du fait de l'accessibilité de leurs membranes et leur volume mort réduit. Ils ont pour inconvénient une surface spécifique modeste.

OBS

Utilisé en osmose inverse et en ultrafiltration, le module plan est le système le plus répandu en pervaporation et la seule configuration concevable en électrodialyse.

Subject field(s)
  • Aircraft Propulsion Systems
  • Launchers (Astronautics)
CONT

The accumulator is intended for heating fuel components in the rocket and space engines and can be used in space engineering, aircraft and other branches of industry. The task of increasing gas heating efficiency, reducing mass of the construction, diminution of dimensions and lowering thermal and hydraulic losses of heated gas is solved by making a heat accumulating element as a mono-unit in the form of cylinder. The covers with branch pipes are recessed in the ends of the mono-unit. The covers are butt joined to mono-unit on conical surfaces through pressurizing end seals at forming the collectors for gas feed and discharge. Plate electric heater and channels or annular slot for flowing gas are located along the longitudinal axis. The axis of channels or annular slot location divides the mass of heat accumulating element into two equal parts. In so doing, porous insert or a set of badly stream-lined bodies is in the channels or annular slot. All units of heat accumulator are coated with gas-dense material.
