Patent CA-2304199-A1 (CA)
Title: Dissolved solids analyzer
Inventor: GARVER THEODORE M
IPC: G01N21/33
Filed: 1998-09-18
Abstract: On-line measurements of an amount of dissolved solids in liquid sample are determined by using both conductivity and UV measurements. More particularly, an amount of dissolved solids in a pulp and paper mill process water or effluent is determined by irradiating at least a portion of a liquid sample with ultraviolet light and subsequently measuring an absorption of the light by the liquid sample. Furthermore the conductivity of the liquid sample is measured and subsequently a computation of the amount of dissolved matter in the liquid sample is made from a first relationship between the measured absorption of the first wavelength by the liquid sample and the mesured conductivity of the liquid sample using a suitably programmed processor.

Patent CA-2313678-A1 (CA)
Title: Method for transferring data upon request using permanent identifier
Inventor: ROLLENDER DOUGLAS HAROLD
IPC: H04B7/26
Filed: 2000-07-10
Abstract: The method for transferring data according to the present invention sends data as part of a first type of permanent identifier associated with an end user in a communication system. The first type of permanent identifier is sent along with a second type of permanent identifier, also, associated with the end user, during a communication procedure prior to establishing a traffic channel in the communication system. Besides the data, the permanent identifier of the first type includes routing information to a home system forming part of the communication system. The end user also stores the sent permanent identifier of the first type, and in response to receiving the stored permanent identifier of the first type in a communication, will generate a new permanent identifier of the first type. In this manner, a destination entity receiving the permanent identifiers of the first type from the home system, can request more data from the end user by having a received permanent identifier of the first type re-sent to the end user.

Title: Supporting multiple services in label switched networks
Inventor: BRUECKHEIMER SIMON DANIEL
IPC: H04Q3/00
Filed: 2000-07-14
Abstract: A telecommunications network architecture provides transport and switching of user services, particularly PSTN/ISDN services. In the network, connections are set up between end points which typically comprise narrow band exchanges serving subscribers. Calls are set up between the end points via call server s using e.g. ISUP signalling between the end points or exchanges and the call server s. The call servers set up connections via a concatenated series of paths or tunnels across an intermediate MPLS network via media gateways serving respective nodes in the MPLS network. User information packets are carried across the MPLS network by the attachment of an appropriate label, this label being removed on egress from the MPLS network to recover the original packet.

IPC: A23L2/62
Filed: 2000-08-29
Abstract: A clouding agent for dry beverage mixes is prepared by first forming a mixture of titanium dioxide and water and then subjecting the mixture to high speed shear. A spacing agent and suspending agent are then added to the mixture and the mixture is again subjected to a high speed shear, followed by spray drying. The resultant clouding agent may contain higher quantities of titanium dioxide than conventional clouding agents to thereby provide increased opacity without increased sedimentation. Further, the method of the invention provides higher throughput through the spray dryer and better yields than conventional methods of preparation.
