Patent CA-2145943-A1 (CA)
Inventor: OBOSU CHARLES B
IPC: F28F1/32
Filed: 1995-03-30
Abstract: The present invention involves a flat fin heat exchanger configuration with a plurality of louvers and a rib raised above the plane of the fin connecting adjacent tube collars.  The raised rib configuration enhances the heat transfer characteristics of the fin, and allows for the use of thinner materials to lower cost without diminishing performance.  The exterior fin surface "scoops" and redirects air flow from the leading edge to the trailing edge of the fin.  This "scooping" effect directs the air flow over and in between the interrupted surfaces, thus breaking up air boundary layer around the fin.  The louvers of the fin are oriented relative to the air flow in such a manner that each louver in effect creates another leading edge contributing to a higher heat transfer coefficient.  Also, the location of the raised rib also enhances the heat transfer between the fin and the circulated air.  The fin collars are also surrounded by a raised portion so that one raised rib and its two adjacent raised portions bordering the collar form a "dog bone" type shape.  The leading and trailing edges are serrated to improve the structural rigidity and create turbulence in the air flow.  Also, the leading and trailing edges are oriented at a slight angle, e.g., 12°, relative to the plane of the fin.  The louvers are oriented at a slightly greater angle than the leading and trailing edges, e.g., 20°-35°.

Title: Starch-natural gum composite compositions as thickening and suspending agents
Inventor: CHRISTIANSON DONALD D
IPC: A23L29/238
Filed: 1993-12-08
Abstract: Starch and a minor amount of natural gum additive are processed together so that the polysaccharide components of each substance are completely dissolved in water, and the resulting blend is recovered. Upon drying, the blend produces a product which hydrates rapidly and which yields dispersions that are not only smooth and viscous, but also possess considerable lubricity. These products are useful in foods as thickening agents, suspending agents, and fat substitutes.

Title: Method for assaying specific antibody
Inventor: TANAKA SATOSHI
IPC: G01N33/543
Filed: 1993-02-04
Abstract: A method for assaying a specific antibody, comprising the following steps (A), (B) and (C): (A) : forming a complex of a labeled antigen-a specific antibody-a carrier-bound antigen in a first reaction system comprising a mixture of the antigen (labeled antigen) against the specific antibody to be assayed, the antigen being bound to the label in advance, the antigen (carrier-bound antigen) against the above-mentioned specific antibody, the antigen being bound to the carrier in advance, and a liquid sample comprising the above-mentioned specific antibody, (B) : mixing the above-mentioned separated carrier and a labeled antigen same as above after separating the above-mentioned carrier after reaction from the above-mentioned first reaction system to give a second reaction system, and (C) : assaying, after separating the above-mentioned carrier after reaction from the above-mentioned second reaction system, the amount of the label bound to the above-mentioned separated carrier.  According to the present invention, a complete complex of carrier-bound antigen-specific antibody-labeled antigen is formed in the first reaction system wherein the two antigens and the specific antibody are reacted by mixing the carrier-bound antigen, the labeled antigen and the liquid sample comprising the specific antibody to be assayed.  When an incomplete complex of carrier-bound antigen-specific antibody is present in the second reaction system, a complete complex can be formed by mixing the separated carrier and the labeled antigen after separating the carrier after reaction from the first reaction system.  Accordingly, the prozoning phenomenon can be eliminated and the target specific antibody can be assayed with high sensitivity by assaying the amount of the label bound to the carrier, after separating the carrier after reaction from the second reaction system.

Title: Process for loosening powdery material
Inventor: PINGEL JOACHIM
IPC: B65D88/66
Filed: 1994-04-29
Abstract: To create a process and device for loosening up pulverous material in particular dye powder for coating objects, ensuring an even feed of material from a container holding the material the container is vibrated to produce an essentially vertical oscillation such that the largest oscillation amplitude of the container runs vertically. The almost exclusively vertical oscillatory movement of the container enables the material contained therein to be evenly loosened up and, for example, drawn out, since without agglomeration  it is extremely well loosened or fluidized, i.e. made to "flow" without additional air supply.

Patent CA-2163425-A1 (CA)
Title: Method and apparatus for measuring flow using frequency-dispersive techniques
Inventor: DIXON ROBERT C
IPC: A61B5/028
Filed: 1994-05-31
Abstract: A system for measuring fluid flow within a conduit, such as blood flow from the heart, includes a heating element that is driven so as to apply heat to the fluid at an upstream position as a series of periodic heat signals. A temperature sensor located downstream measures a local temperature of the fluid and generates an electrical fluid temperature signal corresponding to the local temperature. This signal is then applied to a dispersive filter, which outputs a pulse-like signal in the presence of each periodic heat signal. Fluid flow is then calculated by a processor as a function of the area under an estimated impulse response curve for the channel in which the fluid flows. Each periodic heat signal is preferably sinusoidal and has an instantaneous frequency that varies substantially continuously between a first frequency and a second frequency over a pre-determined active input signal period. In a preferred embodiment, the frequency varies linearly between a first and a second frequency over a predetermined time period. The output signal from the filter, which is itself an estimate of the channel impulse response, is preferably integrated in order to provide a parameter estimate that is inversely proportional to flow. The corresponding method of measuring fluid flow using a frequency-swept input heat signal and matched dispersive filtering is included.

Title: Procede biologique anarobie film fix combin ou non une filtration
Inventor: CARRIERE JULIE
IPC: C12N11/14
Filed: 1996-03-21
Abstract: Ce procédé biologique anaérobie à film fixé a premièrement été inventé pour répondre à un besoin spécifique relativement à la décoloration des eaux rouges de l'industrie minière. Le traitement actuel de décoloration des eaux rouges consiste en un traitement physico-chimique impliquant l'ajoût de nombreux produits chimiques afin de permettre la coagulation la floculation et la sédimentation des particules colloidales en suspension présentes dans l'eau responsables la couleur rouge de l'eau. De plus, un colorant doit être injecté à différents points du bassin de traitement afin de compléter la décoloration de l'effluent. Plusieurs industries minières déversent directement l'effluent coloré par le fer en fines particules en suspension, dans les cours d'eau. Cepedant, la future réglementation gouvernementale ne permettra plus le déversement d'eau colorée et la norme de fer sera plus sévère. Les dirigeants des grandes industries sont donc soucieux face aux technologies physico-chimiques actuelles; ils préfèrent de loin favoriser l'implantation d'un procédé biotechnologique. Cette invention porte sur un procédé biologique anaérobie à film fixé pour le traitement des effluents miniers pouvant être combiné ou non à une filtration, selon le type d'effluent à traiter. Cette technologie consiste en l'application des boues anaérobies incorporant un film fixé pour l'enlèvement de la couleur et du fer. La digestion anaérobie est un procédé par lequel les microorganismes liquéfient, gazéifient et minéralisent les solides organiques pour obtenir l'énergie et les nécessaires à la synthèse cellulaire. L'invention de ce procédé permet l'application du bioréacteur anaérobie au traitement d'effluents liquides contaminés par des produits (fer, silice) jusqu'alors considérés toxiques pour les bactéries. Le procédé a donc été conçu de façon à optimiser l'activité biologique plutôt qu'uniquement en fonction de l'hydraulique. Le support pour la formation du film fixé dans cette invention a été sélectionné en tenant compte de la construction à grande échelle de systèmes à grands débits (par exemple: 35 000 usgpm). Ce type de débit est fréquemment rencontré dans l'industrie minière. La surface du support offre aux bactéries un milieu idéal pour une formation du biofilm rapide et résistante aux variations opérationnelles du procédé.
