Patent CA-2198035-C (CA)
Inventor: DAVIS JOHN
IPC: G01N30/20

Granted: 2000-08-01
Abstract: An access valve suitable for controlling fluid flow into and out of a chromatography column has a central axially movable probe with a head (71) acting as a spool valve in a barrel (6). Axial movement of the probe adjusts the valve between a fully open condition, in which both a first conduit (73) extending through the probe and a second conduit (51) defined around the probe are open to the column interior, a partly open condition in which a second sealing land (76) on the probe closes the second conduit (51), and a fully closed position in which both conduits are closed. The three positions are useful for packing and unpacking chromatography media into and from the column. In the closed condition of the valve, the first and second conduits (73, 51) communicate with one another so that the valve interior can be cleaned while the column is operating.

Abstract: The disclosure relates to a method and an apparatus for heat-treating a food which is packed in a container (1, 14) of flexible or foldably formable packaging material for the purposes of extending the shelf life of the food. In order to accelerate the heat treatment, the container (1, 14) is disposed such that it is, during the heat treatment proper, caused to adopt a first position in which the distance between opposing side wall panels (7) and, thereby, the layer thickness of the packed food, is reduced to a minimum, taking into account the volume of the food and the surface of the packaging material, as well as the shape of the container proper. After completed heat treatment, the container is brought to a second position in which the shape of the container corresponds to that shape in which the container (14), with its packed, heat treated food, is to be distributed, sold or used.

Abstract: La géométrie d'un canal d'écoulement (1) peut subir de fortes variations si l'on conçoit au moins une de ses parois sous la forme d'un paquet de tôles (2), qui est plus ou moins poussé dans le canal par l'arrière au moyen d'éléments d'ajustement (7). L'ajustement peut être effectué uniformément sur toute la largeur du canal d'écoulement (1) ou seulement localement en certains points du canal d'écoulement (1). Pendant qu'un milieu circule dans le canal d'écoulement (1), il est ainsi possible de modifier depuis l'extérieur la résistance à l'écoulement dans la totalité du canal ou bien la résistance à l'écoulement en certains points, ce qui permet de modifier de la façon souhaitée la totalité du flux de matière ou la répartition du flux de matière. Grâce à la meilleure flexibilité du paquet de tôles (2) par rapport aux parois massives des canaux, on obtient de nouvelles possibilités technologiques.

Abstract: Elément en caoutchouc pour trayons, comportant une partie de tête essentiellement à symétrie de rotation par rapport à un axe longitudinal, présentant un orifice d'introduction pour le téton, ainsi qu'un bord de maintien venant en contact sur une douille de gobelet trayeur, ainsi qu'une tubulure d'aspiration raccordée à la partie de tête. La partie de tête, à son extrémité opposée à l'orifice d'introduction pour le téton, se prolonge par le bord de maintien. La paroi de la partie de tête (3) est conçue de façon rigide dans une zone (18) située entre l'orifice d'introduction (49) pour le téton et le passage au bord de maintien (8), et l'extrémité supérieure de la tubulure d'aspiration débouche dans cette partie rigide de la partie de tête. La partie de la tête de l'élément en caoutchouc pour trayons, située entre la partie rigide et le bord de maintien est conçue au moins en partie de façon élastique. Pendant la phase d'aspiration, une force de pression agit sur la zone de la partie de tête, située entre la partie rigide (18) de la partie de tête (3) et le bord de maintien. Cette force tente de déplacer cette partie contre le bord extérieur de la tubulure d'aspiration. Il en résulte un déplacement de la douille du gobelet trayeur vers le haut, tandis qu'il se produit un léger mouvement de la douille du gobelet trayeur vers le bas par rapport au trayon, lors de la phase de détente.
