Title: Vapor-liquid contact apparatus
Inventor: NUTTER DALE EDWARD
IPC: B01D3/20
Filed: 1995-03-17
Abstract: Vapor-liquid contact apparatus includes a plurality of substantially horizontal trays (4) vertically spaced in a vessel (2). Liquid and vapor-liquid mixtures flow horizontally across the trays (4), over weirs (8), and vertically through downcomers (16) to subsequent trays. Each tray has a bubble area (10) with vapor apertures. Each downcomer (16) has an apertured bottom wall (18) which is horizontally coextensive with an unapertured downcomer seal area (6) on the tray therebelow. The downcomer seal area (6) and a portion of the apertured bubble area (10) are elevated with respect to a major portion of the tray's upper surface area. The tray has two outboard panels with integral flanges (50) at their edges, and the upstream ends of these integral flanges are supported on a stationary truss (56) in the vessel. To promote deentrainment of vapor from the mixture in the downcomer, a perforated sheet (80, 82) with inclined corrugations is positioned substantially vertically in the downcomer (16).

IPC: C12Q1/04
Filed: 1995-07-12
Abstract: A method is provided for determining the presence and/or amount of a microorganism and/or its intracellular material present in a sample characterised in that:(a) exposing the sample to a specific binding agent that has been immobilised upon a solid substrate, the specific binding agent being capable of binding to the microorganism or its intracellular material such that it becomes associated with the solid substrate, (b) exposing the solid substrate to an agent capable of making adenylate kinase associated with the microorganism and/or its intracellular material accessible to solutions applied to the substrate, (c) applying a solution containing adenosine diphosphate (ADP) to the substrate under conditions whereby adenosine triphosphate (ATP) may be produced by any adenylate kinase present, and (d) measuring the amount of adenosine triphosphate (ATP) and relating to the presence and/or amount of microorganism or intracellular contents. Step (d) may be carried out using an assay that includes a colour forming reaction, but is preferably carried out by use of luciferase/luciferin reagent to produce light proportional to the amount of ATP produced, and that is detected using a luminometer. Preferably step (c) includes presence of magnesium ions at a molar concentration sufficient to allow maximal conversion of ADP or ATP. Most preferably step (b) and (c) are carried out by adding extractant, ADP and magnesium ions to the sample and incubating the mixture for a predetermined period to effect conversion of ADP to ATP.

Title: Air conditioning apparatus
Inventor: TAKECHI TETSUYA
IPC: B60H1/00
Filed: 1997-06-17
Abstract: An air conditioning apparatus includes a seal wall (9) having a seal surface (9a) to which one end surface of an air mixing door (8) is contacted in the maximum heating state. A defroster warm air leading passage (11) is constructed by the seal wall (9), a warm air guide portion (12) and an inner surface of an air conditioning case (2a, 2b).

Title: Volumetric data organisation method for volume rendering
Inventor: LICHTENBELT BARTHOLD
IPC: G06T15/08
Filed: 1998-05-12
Abstract: A volumetric data organization method for volume rendering that is both cache efficient and efficient for hardware graphics design and utilization. A volume data set (302) is divided (208, 210) up into a number of smaller sub-volumes (304) or blocks through a process called blocking. The size of each sub-volume (304) is a function of the computer system (100) being used and/or the application program (122) being run. Each voxel tuple in a volume data set (302) is converted (212) to a linear address for linear storage in memory. Two techniques are used for blocking: overlapping and non-overlapping. After employing either technique, each sub-volume (304) can be selected as containing desired or non-desired data. The volume rendering system (120) ignores any sub-volumes (304) that do not contain desired data, greatly speeding up rendering time.
