Patent CA-2326343-A1 (CA)
Inventor: OH JAE-SEUNG
IPC: C08F6/24
Filed: 2000-01-28
Abstract: The present invention relates to a catalyst preparation process and an olefin polymerization process with the recycling of co-catalyst, particularly to a method of recycling co-catalyst for the activation of single-site pre-catalyst in the olefin polymerization. This invention, therefore, provides an olefin polymerization process that can reuse expensive co-catalyst for subsequent olefin polymerization so that the total amount of co-catalyst required can be significantly reduced. This invention provides an olefin polymerization process which comprises the steps of: a) preparing activated single-site catalysts by contacting i) supported single-site pre-catalyst with ii) an organic solvent containing co-catalysts; b) separating activated single-site catalysts of step a) from co-catalysts dissolved in an organic solvent; c) olefin polymerization using the separated single-site catalysts of step b) with one or more olefinic monomers; and d) reusing the separated co-catalysts of step b) by recycling an organic solvent containing the separated co-catalysts and contacting them with the supported single-site pre-catalysts of step a).

Title: Image composition system and processing using layers
Inventor: FRANKLIN DAVID W
IPC: G06T11/00
Filed: 1999-03-29
Abstract: A layer based paint system permits painting of an image raster of a composite image while viewing subsequent processing on the images raster. The composite image is mapped to an image processing tree. Each of the elements in the image processing tree is defined by an associated data structure that identifies their parent and children elements in the tree. Each of the elements may be, for example, an image element or a process element. Associated with each image element is an image raster and a transform. Viewing and painting of an image element may be done at any level in the image processing tree.  Painting of the element directly modifies the pixels in the image raster. The pixel coordinates of brush strokes in the viewed image are transformed into pixel coordinates of the image raster material by applying the inverse transform of the viewed layer, the image element layer and all of the intermediate layers to the pixel coordinates of the brush strokes. The profile of the brush stamp is also transformed by applying the inverse transforms of the image layer and all intermediate layers to the pixel coordinates of the brush stamp. Because the process elements are separated from the image elements in the image processing tree, painting may be performed on any layer while viewing the effects of subsequent processing.

Abstract: A method is provided for selecting an optional quality of service (QOS) in a communications network. The method permits the user to make a specific QOS decision every time the network is accessed. The system provides the user with an interface address for every level of QOS. The user automatically makes a QOS  decision by selecting an interface address. A relationship is also created between the requested QOS and the network resources available to support the QOS. Likewise, a relationship is established between the cost of using each QOS level and a fee schedule. The user is billed on an on-demand basis for a specific QOS session, in response to selecting an address. A session server is used to check subscriber credentials and subscription status of the user when requesting a service. The session server also allocates the resources of the network elements to support a user's requested QOS level. A system for automatically selecting a QOS level in response to the choice of an interface address is also provided.

Abstract: A paint color matching and coordinating system comprises an interface for receiving an input reference color; a processor capable of reading a memory, a memory including (1) instructions  readable by the processor and (2) a database of architectural paint colors spanning all or most of the known col or space, and a display generator. In use, the interface of the system receives an input reference color from a user. T he processor selects a "reference paint color" from the database, the reference paint color being visually closer, with respect to color space, to the input reference color than any other paint color in the database. According to the  invention, color space is divided into a plurality of fixed, generally equally sized, non-overlapping, contiguous portions, each color space portion being defined as the space of all colors within a band of hues within color space. The processor selects five sets of paint colors ~~ one set from each of the color space portions that include the five hues tha t comprise the "five-way harmony" of the reference paint color. The processor may also select a sixth set of paint colors from the color space portion that includes the hue of the reference paint color. Finally, the processor direct s the display generator to create a display of color samples of the reference paint color and of the first through sixth se ts of paint colors.

Inventor: MADOUR LILA
IPC: H04W36/10
Filed: 2001-08-16
Abstract: The invention relates to an improved handoff method for mobile IP in a cdma2000 network. During handoff, the A10 connection between the Target PCF and the PDSN is pre-set-up, while the MS is still connected to a MSC, when the Target PCF receives the message from the Target BSC to set up the A8 connection. Furthermore, in the case of inter-PDSN handoff, a tunnel is established between the PDSNs, over which the PPP context eventually is transferred to the Target PDSN. The Target PDSN then sends a message to the MS triggering a re-registration with the HA. The Target PDSN takes over full responsibility for the MS when it receives the Mobile IP Result from the HA, and sends a message to the Serving PDSN to let the latter know that it can release all resources related to the MS.

Title: Device to treat grey water using hydrogen peroxide
Inventor: LEBRETON GREGORY T O
IPC: C02F1/00
Filed: 2001-11-28
Abstract: This invention is a device used to kill bacteria in grey water with hydrogen peroxide. This device is designed for use onboard water vessels that do not have access to sewage systems and are discharging grey water directly into the aquatic environment.  This grey water treatment device uses a water treatment tank to collect and hold grey water for treatment. A switching mechanism senses when grey water is entering the treatment tank and signals a hydrogen peroxide pump to be activated thereby dosing the water within the tank with a solution of hydrogen peroxide. A baffle mechanism within the water treatment tank is used to ensure proper mixing of the grey water-hydrogen peroxide mixture. Following treatment of grey water the solution can then be discharged with substantially fewer bacteria than prior to treatment.

Title: Self-closing fluid dispensing closure
Inventor: ROBINSON PHILIP J
IPC: B65D47/20
Filed: 2002-01-29
Abstract: A fluid dispensing closure includes a housing having a base with an internal thread or bead for securement to a container, and a peripheral wall extending from the base and converging toward an opening spaced from the base. A flexible resilient liner is captured within the peripheral wall of the housing. The liner has a flange extending axially through the opening at the upper end of the housing and radially overlying the peripheral wall of the housing. A flow tip, which has a body with at least one flow passage, is captured within the liner, and extends through the liner flange and the housing opening. Pressure applied to the flange by fluid in the passage resiliently expands the flange away from the flow tip to permit egress of fluid from the passage, and removal of such fluid pressure allows resilient collapse of the liner over the passage.
