Patent CA-2307462-A1 (CA)
Inventor: RAYNER DALANA
IPC: B60R5/04
Filed: 2000-05-01
Abstract: A modular storage container and sleeping platform for removable installation in vehicles. The invention is particularly adapted for use in mini-vans having removable rear passenger seats. The invention comprises a plurality of portable storage units each having a cover adjustable between open and closed positions. Each of the storage units is removably securable to a seat emplacement of the vehicle. When the storage units are assembled together they define a plurality of storage compartments of different sizes and orientations which are accessible from the rear and side doors of the vehicle. In the assembled configuration, the covers together define a flat sleeping platform when they are adjusted to the closed position.

Abstract: An infant carrier assembly and a method controlling an infant carrier position use a base and a movable trolley mounted to a vehicle in a rearwardly facing direction. An infant carrier is detachably mounted to the trolley. The trolley is movable so that the carrier is movable between two reclined positions, 58° and 49° from the vertical to the infant carrier seatback. A  sacrificial link and springs connect the trolley to the base to limit the movement between the two positions. During a front collision, e.g., when 1 or more G-force is created, the sacrificial link breaks away to release the trolley/carrier from the reclined positions to an upright position, where the carrier seatback can be upright up to about 15% (14°) from the vertical.

Title: Optimal equipment allocation
Inventor: KENYON CHRISTOPHER M
IPC: G06Q10/00
Filed: 1998-12-04
Abstract: A method for optimally allocating equipment to jobs at multiple geographic locations to maximize utilization of scarce and expensive resources needed for oil-well fracturing operations (90). The computer implemented method obtains fracturing problem data (91), determines variable parameters (92) and problem constraints (93) and using an algebraic modeling language, builds a fracturing problem model (94) for optimally allocating fracturing equipment to fracturing jobs at multiple geographic locations. The model is expressed as an objective function (95) and a set of problem constraints (95). An optical solution (96) is generated for the model using a solver software problem to satisfy the problem constraints (93) and optimize the objective function (94). The model can be rerun for different oil-well fracturing operations (90) scenarios and optimal solutions (96) generated for each scenario to determine optimal equipment.

Title: Electro-formed bulb shield and method of making same
Inventor: DENLEY RONALD S
IPC: F21V17/00
Filed: 2000-07-05
Abstract: A bulb shield for use in an automotive headlamp assembly, and a method for making same. The bulb shield includes a cup portion and a portion which extends from the cup portion and is configured for mounting to a reflector of the automotive headlamp assembly or to another, proximate structure. When the bulb shield is mounted, the cup portion is preferably generally horizontally aligned with a headlamp bulb in the automotive headlamp assembly, thereby eliminating a "hot spot" which would otherwise be viewable when looking into the headlamp beam. Preferably, at least a portion of the cup portion of the bulb shield is electro-formed.      Such a bulb shield is relatively inexpensive and easy to make, yet can withstand the high temperatures which are typically experienced in an automotive headlamp assembly. Additionally, such a bulb shield can be inexpensively provided, yet meet precision requirements. Still further, such a bulb shield provides enhanced design flexibility and styling consistent with plastic molding.
Patent CA-2313610-A1 (CA)
Inventor: PLOURDE JAMES KEVIN
IPC: H01S5/024
Filed: 2000-07-05
Abstract: A unique method and apparatus for locking on an absolute wavelength of laser light output by a laser package by actively compensating for a change in the temperature of an etalon optical fitter is disclosed. Changes in etalon response characteristics due to temperature changes are compensated for by the addition (or subtraction) of an output voltage offset to the voltage control signal sent to the Thermo-Electric Cooler (TEC) from a controller within the laser package. The voltage offset is calculated by monitoring the etalon temperature. The voltage offset value provides for active compensation of changes in the etalon temperature and effectively "readjusts"  the output of the laser as if the etalon temperature itself had been readjusted.

The object server (206) provides a unified object model for all of the data received. The virtual application service communicates with personal agent frameworks (208) which contain presentation cells (302) and service agents (304). The service agents provide the personal agent framework with access to the object server.

Title: Navigating network resources using metadata
Inventor: POPP NICOLAS
IPC: G06F17/30
Filed: 1999-02-02
Abstract: Mechanisms for associating metadata with network resources, and for locating the network resources in a language-independent manner are disclosed. The metadata may include a natural language name of the network resource, its location, its language, its region or intended audience, and other descriptive information. The owners register the metadata in a registry (10). A copy of the metadata is stored on a server (60) associated with a group of the network resources and in a registry that is indexed at a central location (32). A  crawler service (24) periodically updates the registry by polling the information on each server associated with registered metadata. To locate a selected network resource, a client (70) provides the name of the network resource to a resolver process. The resolver process provides to the client the network resource location corresponding to the network resource name.  Multiple metadata mappings can be established for the same network resource.

IPC: C09D17/00
Filed: 1999-01-22
Abstract: A process for preparing a carboxylated cellulose ester from oxidized cellulose is described. The carboxylated cellulose esters have improved solvent solubility and coating resin compatibility when compared to cellulose esters made from regular grade cellulose. The process comprises activating the oxidized cellulose with water. The activated oxidized cellulose is then dehydrated by displacing the water with acetic acid and optionally displacing at least some of the acetic acid with butyric acid or propionic acid. After dehydration the activated cellulose is reacted with an esterifying reagent in the presence of a catalyst at about 0 ~C. The temperature is gradually increased to a level sufficient to complete reaction and to obtain an intrinsic viscosity ranging from about 0.2 to about 1.6 dl/g. The reacted solution is then hydrolyzed to obtain a hydroxyl content ranging from about 0.05 to about 1.0. The catalyst is neutralized with a neutralizing agent and the solution is optionally filtered and the carboxylated cellulose ester is then precipitated with a precipitating agent. The invention also relates to carboxylated cellulose esters prepared by the process described above as well as high solids coating compositions containing carboxylated cellulose esters made by the above process.

Patent CA-2340485-A1 (CA)
Title: Portable self-energizing pressure sprayer
Inventor: WALKER SCOTT A
IPC: B05B9/08
Filed: 2001-03-13
Abstract: A pressure sprayer is pressurized automatically with movement of the sprayer and maintains adequate pressure during non-movement to allow the ejection of an amount of liquid before needing re-pressurization. The pressure sprayer includes wheels that allow the pressure sprayer to be mobile. A cam is attached to the axle of the wheels which rotates with the rotation of the axle/wheels. A pressure pump is associated with the cam such that movement of the cam causes the pressure pump to pump liquid from a holding tank to an accumulator or directly to a spray wand in communication with the pump. The liquid may be sprayed (ejected) from the accumulator during both movement (pumping) and non-movement (no pumping) of the sprayer, while the liquid may be directly sprayed from the holding tank only during movement (pumping) thereof. Thus, as the wheels rotate due to moving the pressure sprayer, the cam causes movement of the pressure pump to fill the accumulator with the liquid under pressure. The pressure pump is adapted to obtain liquid from the holding tank and provide that liquid to the pressure accumulator. A relief valve is provided to relieve the buildup of pressure during movement of the wheels when no spraying is taking place.
