Patent CA-2421863-A1 (CA)
Title: Evaluation of multilayer reservoirs
Inventor: POE BOBBY
IPC: E21B43/14
Filed: 2001-09-12
Abstract: A method of and process for fractured well diagnostics for production data analysis for providing production optimization of reservoir completions via available production analysis and production logging data provides a quantitative analysis procedure for reservoir and fracture properties using commingled reservoir production data, production logs and radial flow and fractured interval analyses. Production logging data is used to correctly allocate production to each completed interval and defined reservoir zone. The method supports computing the individual zone production histories of a commingled multi-layered reservoir. The data used in the analysis are used to construct the equivalent individual production histories. These individual completed interval production histories can then be evaluated as simply drawdown transients to obtain reliable estimates of the in situ reservoir effective permeability, drainage area, apparent radial flow steady-state skin effect and the effective hydraulic fracture properties, namely, half-length and conductivity.

Title: Method for reducing the sox emission from a plant for manufacturing cement clinker and such plant
Inventor: SKAARUP JENSEN LARS
IPC: C04B7/52
Filed: 2001-09-19
Abstract: A description is given of a method as well as a plant for reducing the SOx emission from a plant for manufacturing cement clinker by which cement raw meal is preheated and burned in a plant comprising a cyclone preheater (1) and a kiln (7). The method is peculiar in that a catalyst in the form of a chloride compound and/or a mixture of several chloride compounds is introduced into the preheater (1) at its uppermost or next-to-uppermost cyclone stage (2, 3), that the catalyst is directed down through the preheater (1) to the kiln (7), that a partial amount of the kiln exhaust gas stream containing the catalyst in vaporized form is extracted from the kiln (7), that the extracted exhaust gas stream is cooled off so that the catalyst is present in solid form, that solid matter is separated from the cooled exhaust gas stream and that at least some of the separated solid matter containing the catalyst is recirculated for renewed introduction into the preheater (1).Hereby is obtained an effective reduction of the SO2 emission. The reason for this is that chloride compounds and/or a mixture of several chloride compounds will promote the reaction catalytically of SO2 with CaO for formation of CaSO3 and it will further promote the reaction of SO2 with CaCO3 for formation of CaSO3 and CO2. Since CaCO3 is present in great abundance, the SO2 reduction may be effected without any use of extraneous chemicals.

Title: Apparatus for controlling laser penetration depth
Inventor: ANDERSON R ROX
IPC: G02B6/42
Filed: 2001-11-21
Abstract: The invention features systems and tools for controlling the optical penetration depth (OPD) of laser energy, e.g., when delivering laser energy to target tissue in a patient. The systems and tools control the OPD by controlling the incident angle at which the laser energy (364) is delivered to the target area of the patient. Embodiments of the invention include an optical coupler (368) that permits a user to vary the incident angle and thereby selectably control the OPD of incident laser energy (364). Fabricating the optical coupler (368) to have a refractive index greater than that of the target tissue can enhance the range of selectable OPDs. The laser energy (364), which is delivered to the desired depth, can cause alteration of the target tissue by, e.g., heating, ablation, and/or photochemical reaction.
Patent CA-2430184-A1 (CA)
Inventor: LARISCH BELINDA C
IPC: B01J20/32
Filed: 2002-01-07
Abstract: Using zeolites as the active adsorbent, adsorbent laminates have been fabricated with various sheet supports. These adsorbent laminates have been successfully operated for oxygen enrichment at high PSA cycle frequencies, such as upwards of at least 150 cycles per minute. Methods for making suitable adsorbent laminates are described. The methods generally involve forming a slurry comprising a liquid suspending agent, an adsorbent and a binder. Laminates are made by applying the slurry to support material or admixing support material with the slurry. The slurry can be applied to support material using a variety of techniques, including roll coaters, split roll coaters, electrophoretic deposition, etc. One method for making laminates by mixing support material with the adsorbent slurry comprises deposition the slurry onto a foraminous wire, draining the slurry material, and pressing the material to form a ceramic adsorbent paper. Spacers can be formed on adsorbent laminates to space one laminate from another. The spacer dimensions can be uniform, or can vary along a laminate, such as increasing in height from a first end to a second end of the laminate. Gas flow-through apertures also can be formed on laminates. The laminates are adjacent one another to define flow channel between adjacent bodies, whereby a portion of a gas flowing through the flow channels flows through the apertures to facilitate pressure equalization in the adsorbent structure.

Title: Method and apparatus for predicting human characteristics
Inventor: MOTT JACK E
IPC: G06F17/10
Filed: 2003-06-17
Abstract: A method for predicting human characteristics obtains a subject's responses for a stimulus field (SF). The SF is a compact psychometric instrument having a relatively small number of items. Each item comprises a pair of descriptors separated by a scale. The responses are compared to responses in a reference library which contains responses for a number of reference subjects for whom the human characteristics have been measured. A subset of the reference subject responses that are most similar to the subject's responses are identified. h weighted combination of the measured characteristics of the reference subjects in the subset is used to predict one or more corresponding characteristics of the subject.

Abstract: L'invention concerne des cathéters de stabilisation pour l'administration de protéine(s)-médicament(s) à un patient. Selon les variantes décrites dans l'invention, il s'agit de cathéters maintenant ou préservant une forme biologiquement/pharmacologiquement active de protéine-médicament, aux fins d'administration sur un site corporel. Selon des variantes spécifiques, les cathéters comportent un tubage à couche de polymère hydrophile et mobile qui contribue au maintien ou à la préservation d'un conformère actif de la protéine-médicament. Dans une telle configuration, les cathéters empêchent la perte de protéine-médicament (par exemple, insuline) sur le site d'administration. Selon d'autres variantes, le tubage comporte une couche de matériau empêchant sensiblement la diffusion de petites molécules de stabilisation de formulation d'insuline hors du cathéter, et empêchant sensiblement la pénétration de petites molécules de déstabilisation de formulation d'insuline dans le cathéter, durant une période de perfusion d'insuline. Dans tous les cas, ces cathéters maintiennent l'effet stabilisateur d'une formulation d'insuline spécifique, et empêchent donc sensiblement la formation des occlusions/dépôts durant une période d'administration d'insuline. D'autres variantes encore présentent une combinaison des caractéristiques décrites.

Abstract: A flyer bow machine for twinning or twisting wire or cable is provided in which a moving carrier strip is provided on the flyer bow. The carrier strip moves along the bow in the same direction as the wire or cable is traveling, and preferably, moves at the same speed as the wire or cable. As a result, tension on the wire or cable as it passes though the flyer bow machine is reduced. Thus, higher throughput rates of wire or cable, or improved quality of wire or cable, can be achieved.
