Abstract: Un dispositif portable de lecture sans contact d'une étiquette saisit une image composée d'indices informatifs bidimensionnels (20) sur une étiquette (25). Les données de l'image saisie sont décodées par un décodeur. Le lecteur d'étiquette constitue une partie d'un terminal informatique (10) comportant un clavier (35), ainsi qu'une plage d'affichage (45) et de saisie de signature (40). A réception d'un signal de départ provenant du circuit du terminal informatique, le lecteur exécute automatiquement les étapes nécessaires à la saisie des indices informatifs de l'étiquette. Le lecteur comporte des indices de repérage permettant à l'utilisateur de diriger correctement la caméra. Un dispositif de détection de position détermine le moment où l'étiquette cible se trouve à l'intérieur de la profondeur de champ de la caméra. A ce moment, le lecteur détermine la vitesse d'obturateur nécessaire à une exposition correcte par mesure de la lumière réfléchie par l'étiquette. Le lecteur saisit ensuite l'image de l'étiquette, qui est décodée par le décodeur. Les données de sortie correspondantes sont ensuite transmises au terminal informatique (10).

Granted: 2004-07-27
Abstract: There is disclosed a method for removing volatile materials, which comprises adding a blowing aid to a polymer composition containing volatile materials, mixing them in a static mixing apparatus, and extruding the resultant mixture by an extruding apparatus into a devolatilizing tank, thereby the mixture is made to be blown, to cause removal of volatile materials. First, the blowing aid (6) is discharged with an addition nozzle apparatus (2), in a direction opposite to the direction of the flow of the polymer composition (1), to be added, and the polymer composition is introduced into the static mixing apparatus (3), at a pressure at which the blowing does not take place, thereby mixing them. Then, using the extruding apparatus (11), the resultant mixture is extruded into the devolatilizing tank (4), so that the polymer is made into a blown product at such a temperature and a pressure that the blowing coefficient B given by the expression (1) becomes 1.4 or more, thereby causing removal of volatile materials:      Expression (1) B = A'/A wherein A represents the cross-sectional area of an extruding apparatus, and A' represents the average cross-sectional area of the polymer composition in a direction perpendicular to the vertical direction of the blown polymer composition, at a point where the polymer composition is dropped from the lower part of an opening section of the extruding apparatus vertically 50 cm to 1 m. The method can give a polymer composition having residual volatile materials in very small amounts, by removing volatile materials continuously with high efficiency.
