Title: Electrocoalescent system for decontaminating water streams
Inventor: JOHNSON DENNIS E J
IPC: C02F11/121
Filed: 1996-01-25
Abstract: An improved electro-coalescent/magnetic separation (ECMS) system for removing contaminants from water, including desalinization, comprises a device (12) for exposing a stream of water to be treated to an electric field, followed by introduction of ionized coagulating substances from generator (26), including ionized gases and/or metal ions, into venturi (24), followed by plural filter stages (18, 20). The first filter stage (18) may comprise a polarizable glass, alumina, or ceramic media provided as a bed in a tank with an underdrain, so as to provide substantial residence time. A polishing filter (20) may comprise a very fine fiber or organic gel filter element confined between relatively flexible electrically-conductive screen members and provided with a DC power supply to polarize the filter. This assembly is confined between relatively rigid, perforated members such that the filter assembly can move slightly upon backwash to dislodge caked-on contaminants or the like, while preserving the structural integrity of the filter assembly.

Abstract: L'objet de la présente invention est un système d'adsorption modulée en pression. Le système d'adsorption modulée en pression comporte une pluralité de lits d'adsorbant primaire et au moins un lit d'adsorbant secondaire. Le flux de gaz d'alimentation circule vers un lit d'adsorbant chargé d'adsorbant qui adsorbera de préférence certains composants du gaz d'alimentation. Pendant ce temps, les composants qui ne sont pas adsorbés de manière préférentielle circulent à partir du lit d'adsorbant. Une fois que l'adsorbant est saturé des composants adsorbés, le flux de gaz d'alimentation est interrompu. L'adsorbant est complètement chargé du composant préalablement adsorbé, et un gaz d'alimentation occupe l'espace libre entre les particules d'adsorbant. Ce lit d'adsorbant primaire subit une régénération par dépressurisation partielle à travers le lit d'adsorbant secondaire, suivie d'une dépressurisation complète pour atteindre une basse pression finale. Il peut y avoir deux ou plus de deux lits d'absorbent primaire et il y aura au moins un lit d'adsorbant secondaire.

Title: Red blood cell spillover detection technique
Inventor: GIBBS BRUCE W
IPC: G01N15/06
Filed: 1997-11-04
Abstract: An apparatus and a method are provided to monitor a generally transparent blood tube at a location that is downstream from a blood separator in order to detect the presence of red blood cells in a tube that is intended to carry a different blood component, for example platelets. A red light source and a green light source are located id relation to the tube so that red light emission and green light emission are directed toward the tube and toward the flowing blood component(s) that is carried within the tube. The red light source produces a red reflection intensity from red blood cells whose magnitude increases as a function of an increase in the concentration of red blood cells. The green light source produces a green reflection intensity from the red blood cells whose magnitude decreases as a function of an increase in the concentration of the red blood cells. These two light reflections are sensed by means of one broadband photodetector, or by two band-specific photodetectors, that are located on the same side of the tube, so as to be responsive only to reflected light. An output is provided by detecting the ratio of the magnitude of the red reflection intensity to the magnitude of the green reflection intensity.
