Title: Method and burner for introducing fuel to a kiln
Inventor: OHLSEN IB
IPC: F23C1/04
Filed: 1998-01-13
Abstract: A method as well as a burner are provided for introducing solid, liquid or gaseous fuel into the burning zone of a kiln, such as a rotary kiln for manufacturing cement clinker or similar products, where fuel is conducted through substantially concentric ducts (1, 6) and where primary air is conducted through two likewise concentric and annular ducts (8, 9) arranged around the fuel ducts, where the air in one of these air ducts (9) is made up of axially flowing air, whereas the air in the second air duct (8) comprises air which is caused to rotate about the centre axis of the burner, and where the portions of primary air can be -independently controlled. The peculiar feature of the burner is that the primary airstreams are mixed at a relatively low velocity in a collecting duct (15) into a primary airstream which is subsequently accelerated up to a desired, relatively high velocity prior to being injected into the kiln via an annular nozzle (14). There is thus obtained effective mixing of fuel and air in an operationally reliable manner with a minimum loss of pressure, and the flame shape can be adapted to the optimum desired.

Abstract: La présente invention concerne un procédé permettant d'effectuer le diagnostic et le traitement des lymphomes hodgkiniens (lymphogranulomatose), qui est fondé sur l'expression de l'exon variant v10 du gène CD44 comme marqueur ou cible moléculaire. Il y a une corrélation importante entre l'expression de v10 et le stade de la maladie et également le pronostic relatif à celle-ci. Selon une forme de réalisation avantageuse, on utilise des molécules d'anticorps spécifiques du v10 pour mesurer l'expression de l'exon dans des échantillons. Selon un autre mode de réalisation avantageux, on utilise des anticorps spécifiques du v10 radiomarqués pour traiter les lymphomes hodgkiniens.

Title: Thiazole benzenesulfonamides as .beta.3 agonists for the treatment of diabetes and obesity
Inventor: MATHVINK ROBERT J
IPC: A61K31/4439
Filed: 1998-01-23
Abstract: Thiazole substituted benzenesulfonamides are .beta.3 adrenergic receptor agonists with very litte .beta.1 and .beta.2 adrenergic receptor activity and as such the compounds are capable of increasing lipolysis and energy expenditure in cells. The compounds thus have potent activity in the treatment of Type II diabetes and obesity. The compounds can also be used to lower triglyceride levels and cholesterol levels or raise high density lipoprotein levels or to decrease gut motility. In addition, the compounds can be used to reduce neurogenic inflammation or as antidepressant agents. The compounds are prepared by coupling an aminoalkylphenyl-sulfonamide with an appropriately substituted epoxide. Compositions and methods for the use of the compounds in the treatment of diabetes and obesity and for lowering triglyceride levels and cholesterol levels or raising high density lipoprotein levels or for decreasing gut motility are also disclosed.

Patent CA-2289293-A1 (CA)
Inventor: HUNDEBY DAVID R
IPC: A01B73/02
Filed: 1999-11-10
Abstract: A control system is provided for automatically deploying the field markers on an agricultural planter in an alternating manner without requiring operator input. The control system utilizes a proximity sensor to determine whether the tool bar is coming from the lowered working position to the raised headland position or vice versa. Solenoid valves in the hydraulic circuit to the field marker actuators are activated to retract both actuators to retract the deployed one of the field markers when the tool bar is moved into the headland position. When the tool bar is returned to the working position after making a turn at the field headlands, the control system remembers which field marker had just previously been deployed and then extends the other field marker to score the field. The control system permits the operator to remain attentive to the turning of the tractor and implement at the headlands and the setting of the planting implement into the ground at the proper location for planting the crop.
Patent CA-2292123-A1 (CA)
Title: Method and system for modifying executable code to add additional functionality
Inventor: TINKER JEFFREY L
IPC: G06F9/445
Filed: 1999-12-08
Abstract: A system for modifying a compiled executable code file by adding patches that add functionality when the modified executable code file is executed. The modifying is performed without recompiling, relinking or rewriting the code file. Adding a patch involves creating a patch handler which when executed causes the patch statements to be executed, and may involve replacing one or more existing compiled instructions in the file with patching instructions to transfer flow of execution to the appropriate patch handler. The instructions replaced by the patching instructions can also be added to the patch handler. Patches can also include code statements which form a complete module, such as an invokable routine, which can be referenced by other patch statements to cause the module to be executed.  Specialized trace requests can also be added as patch statements. The trace requests will make specified information about the current execution of the executable code file available to a software developer. Patch statements can include variables and expressions that will be evaluated in the context of the appropriate current variable scope, regardless of whether the scope is defined within the patch or by existing compiled instructions. After patches have been added, they can be disabled so as to prevent their execution without removing the patching instructions from the compiled executable file.  Patches can also be qualified with conditions such that the patch will be executed only when the conditions are true at the time of execution.

Title: Air desiccant canister
Inventor: STROPE CLAUDE F
IPC: B60T17/00
Filed: 2000-04-18
Abstract: A spin-on air desiccant canister or dryer far the air brake pneumatic/compressor system of a vehicle. The spin-on air desiccant canister includes an outer cylindrical steel canister, an aluminum cast baseplate, and an internal desiccant bed that may be held in place by an internal desiccant container. The baseplate is adapted to connect the canister to the pneumatic circuit and includes a central outlet port for return of dried air and peripheral inlet ports for receiving compressed wet air. The desiccant container holds molecular desiccant beads for removal of the humidity from the compressed air. Baffle plates are located in the desiccant container and divide the desiccant bed into multiple different layers. A spring compresses the baffle plates and the desiccant bed to maintain a compact desiccant bed. Some of the baffle plates includes air ports at their center while the other baffle plates include air ports at their outer radial periphery. With this arrangement, the air flow passage through the desiccant bed travels radially inward and outward through consecutive layers in the desiccant bed. This increases the travel distance for air without increasing the axial length of the filter. A pressure relief valve may also be connected to the baseplate for exhausting excessive pressure build up in the canister.
