Abstract: A method and apparatus for collecting a cell sample of desired concentration on a filter collection site from a biological liquid specimen in a container.  Specimen liquid is moved through a filter while the volume rate of liquid flow through the filter is monitored. The monitored liquid flow rate is compared to a reference value, and liquid flow through the filter is terminated when the ratio value. The predetermined ratio value preferably is a function of the protocol for processing the specimen. An alternative method and apparatus relies on the rate of change of the measured weight of the container.

Granted: 2010-12-07
Abstract: A seam plate implement assembly comprises a substrate having a longitudinal extent and upon which a plurality of seam plates are fixedly disposed at predetermined uniformly spaced longitudinal positions which correspond to the transverse spacing defined between the crest portions of an underlying corrugated roof decking substructure. In this manner, when a particular one of the membrane plates is fixedly secured to one of the crest portions of the underlying corrugated roof decking substructure by suitable threaded fasteners, the remaining membrane plates will be automatically properly aligned with the other crest portions of the underlying corrugated roof decking substructure so as to automatically ensure proper and secure fixation of the seam plates upon the roof decking assembly. When the seam plate or membrane plate implement assembly is used with a non--corrugated roof decking substructure, the seam plates are disposed at predeterminedly spaced locations upon the substrate so as to provide the environmental membranes with sufficient uplifting force resistance. The substrate may have a C-shaped or V-shaped cross-sectional configuration for enveloping each one of the seam plates, or may comprise a mesh member through which prong members of the seam plates are extended and folded so as to secure the seam plates upon the substrate.

Abstract: Une pile à combustible céramique est supportée dans une plaque d'interconnexion conductrice de chaleur, et une pluralité de plaques forment un chauffage conducteur appelé un empilement. La connexion d'une pluralité d'empilements forme un bâton de piles à combustible. En connectant une pluralité de bâtons d'un bout à l'autre, on obtient une chaîne de piles à combustible. La chaîne peut avoir une longueur de 1 000 pieds ou plus et être dimensionnée pour pénétrer dans une couche de ressources souterraines, par exemple de l'huile. Un préchauffeur amène la chaîne à une température de fonctionnement de plus de 700.degrés.C.
