Patent CA-2297496-A1 (CA)
Inventor: DYCK ALLAN ROBERT
IPC: G06F13/16
Filed: 2000-01-24
Abstract: A primary objective of prior art memory management schemes is to provide rapid access to a table of used/free memory page addresses to facilitate location and allocation of the next available free page as quickly as possible (e.g. within a few hardware clock cycles).      But it is not always essential to allocate new pages within the smallest possible number of hardware clock cycles. Furthermore, some tasks need not "see" (or access) more than a few pages (possibly as few as 1 or 2 pages) at a time. By exploiting these factors, the present invention facilitates management of a collection of pages using an address table containing the smallest possible number of bits (i.e. N bits for a memory divided into N pages). The invention also provides a method of accessing a small number of pages via simple multiplexed address selection. The invention is well suited to use in embedded chip applications which pass data through a set of data storage buffers, as is common in a packet switched network environment.

Title: Huff and puff process utilizing nitrogen gas
Inventor: MILLER BERNARD J
IPC: E21B43/16
Filed: 2000-06-07
Abstract: A cyclic or "huff and puff' enhanced oil recovery process utilizes purified nitrogen gas as the injection gas. The purified nitrogen gas is preferably generated near the well site by the use of a membrane separator.     The resulting purified nitrogen gas comprises at least about 90% by volume nitrogen with the remaining gas mixture fraction being primarily oxygen.    The producing well is shut in. The gas mixture is injected down through the well into the formation. The well is then shut in allowing the gas mixture to soak into the formation for a predetermined period of time of at least 7 days and in some cases as much as 180 days or more. Then the well is placed on production and additional hydrocarbons are produced back from the same well into which the nitrogen gas was injected.

IPC: A61F2/958
Filed: 1999-02-18
Abstract: A balloon catheter having a first balloon member and a second distal expandable member. The increased distal profile of the catheter with inflation of the second distal expandable member can deflect the distal-most end away from stent walls and edges. Another catheter has a distal region including longitudinal slits and a pre-stressed body configured to expand upon exposure to warm body fluids. Another catheter has a distal region including a first, inner tube disposed about a second, innermost tube. The inner and innermost tubes are secured at the distal-most end. The distal region includes longitudinal slits through the inner tube, thereby defining flaps between the slits. The innermost tube can be retracted relative to the inner tube disposed about the innermost tube, thereby causing the longitudinal flaps to expand outward, thereby increasing the maximum radial extent of the distal region. In yet another embodiment, a balloon catheter having a first guide wire tube is provided. A second guide wire tube is also provided, adapted to be received within the larger, first guide wire tube.

Title: Thin-layer chromatography apparatus
Inventor: SPANGENBERG BERND
IPC: G01N30/95

Abstract: The invention relates to a thin-layer chromatography apparatus (1) comprising a plurality of optical light guides to inject light from a light source (2) onto a thin-layer plate (4) and to feed light from the thin-layer plate to an optical examining device (6). To obtain a robust, compact thin-layer chromatography apparatus having a high spectral and spatial resolution, with which there are only minimal disturbances, if any, caused by ambient light and which is nonetheless economical to produce, the invention provides for the emitted-light guides (3) and or received-light guides (5) to be positioned in a regular geometrical pattern in relation to each other either towards or away from the plate, as represented by the rows (11 and 14). The light spots emitted by the emitted-light guides and the field of vision of the received-light guide overlap in an adjustable manner (linear movements 12b, pivoting movements 12a), as regards spatial resolution and light yield. A thin-layer plate (4) which is oriented in a planar manner by reference measurement and has a chromatography path (10) is displaced by a control unit (7) in relation to the light guides (8) which are at a distance of a few 100 µm and is examined (6) and evaluated (7) by spectroscopy for fluorescence, reflectance and/or absorption. Key words include, analytics, analysis, thin-layer, chemistry, HPTLC, HP-TLC, chromatogram, automatically, CCD, spectrum, spectrometer.
