Title: Method, switching means and telecommunication system for performing data communications between subscriber stations
Inventor: SIEPPI JUKKA
IPC: H04M7/00
Filed: 1998-12-16
Abstract: A switching means (BSC/MSG/VLR) of a mobile radio communication network (PLMN) contains a subscriber type determining means (SSTDM) which determines on the basis of call set-up messages whether in particular the second subscriber station (WS) of an IP-network (INTRANET) is capable of performing an audio data encoding/decoding, in particular a GSM speech encoding/decoding. The subscriber station type determining means (SSTDM) switches off an audio data encoding/decoding means (CODEC) in a base station controller (BSC) if the second subscriber station (WS) is capable of performing the speech encoding/decoding. Thus, a deterioration of the speech quality due to performing unnecessary audio data encoding/decoding is avoided and the bandwidth in the PLMN/data network can be utilized more efficiently.

Inventor: STONE THOMAS EDWARD
IPC: C11D17/04
Filed: 1999-04-21
Abstract: A process for producing a water-dispersible non-particulate detergent product from low density particulate detergents includes the step of providing a low density particulate detergent composition having an intra-particle porosity in a range of from about 10 % to about 90 % by volume. The process further includes the step of adding a liquid to the low density particulate detergent composition in an amount sufficient to reduce the intra-particle porosity by at least about 10 %. The process then includes the step of compacting the low density particulate detergent composition having reduced intra-particle porosity by applying a pressure in an amount sufficient to form the water-dispersible non-particulate detergent product having a density of at least about 1000 g/l. This process enables the manufacture of a rapidly dispersing non-particulate detergent product that sinks in water.

Patent CA-2330946-A1 (CA)
Inventor: DONG ZUOMIN
IPC: H01M8/04
Filed: 1999-04-30
Abstract: A fuel cell stack (10) assembly comprises an aligned series of multi-function strata (panels) (30) alternating with and interposed between a mating series of electrochemically active strata (12). In a proton exchange membrane (PEM)-type fuel cell stack, the electrochemically active fuel cell strata include membrane electrode assembly (MEA) strata. The multi-function panels provide structural integrity and electric circuit continuity within the stack. Each multi-function stratum comprises an open spring conductive layer (34), such as an undulate or corrugated layer, sandwiched between a pair of relatively rigid conductive layers (32, 36) that isolate the open spring layer from the reactant gases. The layers of the multi-function stratum together constitute a distributed spring array exerting a compressive force acting in the stack dimension, each open spring layer bearing compressively against the rigid conductive sheets between which it is sandwiched. This distributed spring array facilitates the maintenance of dimensional integrity within the stack, permitting an external manifold to be provided for the supply and exhaust of reactant gases to and from the stack. The spaces provided between the open spring elements serve as conduits for cooling air, so that cooling air may flow over the corrugations to cool the stack. A simple economical frame structure and associated cover plates and separator bars for the fuel cell stack form and enclose separate plena for the supply and exhaust of reactant gases for the fuel cells in the stack.

Patent CA-2341095-A1 (CA)
Inventor: CHEN XIANZHEN
IPC: H02K29/00
Filed: 2001-03-16
Abstract: A stator winding is divided into segments enabling the stator current to be controlled to flow within a selected portion of the stator winding. The number of "active" turns of the stator winding, that is, the number of turns in which stator current is flowing, determines the motor performance, and thus the speed range over which the motor will operate efficiently. The overall speed range of the motor can be extended by selectively connecting a power supply across one or more segments to thereby dynamically adjust the number of "active" turns of the stator winding.      A permanent magnet brushless DC motor incorporating the stator winding of the present invention can be designed having an overall performance characteristic that is similar to that of a series polar direct current motor. It has a higher torque at low speeds, providing good starting and climbing performance of a vehicle incorporating such a motor. The motor can operate efficiently at moderate and high speeds, and can be controlled using a simple control system, thereby enabling simplified operation of an electric vehicle incorporating the motor.
