Abstract: An improved packaging machine that has improved features for feeding a web in the form of a continuous chain of bags through the machine while helping maintain the web in proper alignment and proper tension, and having additional features for improved loading of the bags. The improved web feed includes a dancer assembly equipped with a pair of nips that are driven at speeds responsive to the rate of web travel through the machine so that tension between a web supply and the dancer nips is isolated from the downstream portions of the web. A web feed mechanism which automatically threads the web through baggers is also provided. The web feed mechanism includes elastic belts which fractionally grip the web to isolate the tension in the section between the dancer nips and the belts from the tension of the web feed mechanism.      Nips adjacent the load station and at the downstream end of the web feed mechanism have surface speeds exceeding the surface speed of the belts to maintain tension on the web through the web feed mechanism and effect a slight pre-opening of the bags before they are delivered to the load station.  Other features include a cantilevered support of the web supply and bagger, a bagger support which functions as a plenum, an improved dancer assembly, and improved application of compressed air for bag opening.

Abstract: When, during the replay of the VTR, time codes are sent to the control unit and the special part detection device supplies detection data to the control unit, the control section displays an indication of the special parts being detected and the time codes found and transferred at detection time on the display device and the video monitor, and writes the detection data and the corresponding time codes into the memory. Hence, the contents of the special parts detected in the reproduced video (tape scratch, flicker, special pattern or change in average luminance, and the levels of these) and the time codes found and transferred at detection time are stored, thus enhancing the efficiency of the editing of cutting off the special parts.

Title: Procede de reconnaissance de caracteres sur une matrice de pixels
Inventor: VAN SAUN RICHARD A
IPC: G06V10/44
Filed: 1997-09-05
Granted: 2003-04-08
Abstract: Pour procéder à la reconnaissance de caractères, on catégorise un chiffre grâce à une seule description contenant trois ensembles de caractéristiques. Selon le procédé de la présente invention, les lignes sont localisées par extension ou contraction de l'image d'origine du chiffre, de façon à ce que celle-ci puisse s'insérer dans une matrice de pixels à espaces clairsemés. L'image est ensuite rétrécie de façon à définir des lignes (32) et à ne pas néantiser les lignes faisant du chiffre un chiffre unique. Une fois que le chiffre est rétréci, on utilise une logique floue pour définir pour chaque ligne un ensemble de coordonnées faisant partie d'un système de coordonnées cartésiennes. Une fois que toutes les lignes ont été situées, on situe les points d'extrémité de chacune d'elles ainsi que leurs points d'intersection (44). Ces trois ensembles de caractéristiques sont codés, ce qui donne trois valeurs, telles des entiers à 64 bits (50). Ces trois entiers sont ensuite utilisés en tant que clés de recherche en vue de l'interrogation d'une base de données relationnelles contenant les ensembles d'entiers des caractères connus (53).

Granted: 2007-01-09
Abstract: La présente invention concerne un procédé de dynamitage contrôlé. Ce procédé consiste à disperser un explosif (9) dans un trou de mine (1) pour former un explositf dispersé dont la densité apparente moyenne est inférieure à celle de cet explositf (9) avant sa dispersion et à faire détoner ledit explosif dispersé. Traditionnellement, l'explosif (9) est dispersé dans l'air. Toutefois, il peut être dispersé dans d'autres matrices comme d'autres gaz ou liquides ou dans des gaz comprenant des matières particulaires. L'explosif (9) peut être dispersé selon un certain nombre de techniques différentes, par exemple, par la décharge d'un fluide sous pression ou par la détonation d'une faible charge propulsive ou par une chute par gravité dans le trou de mine. La présente invention est particulièrement utile lorsqu'une concentration réduite d'énergie explosive est nécessaire, par exemple, dans des conditions de contrôle périmétrique, de prédécoupage ou avec des roches tendres. Le procédé selon l'invention permet de contrôler le processus par la dispersion de la composition explosive (9) dans un trou de mine avant le dynamitage. La dispersion de cette composition explosive (9) dans un trou de mine (1) permer d'obtenir in situ une composition explosive à faible densité.
