Patent CA-2194075-C (CA)
Title: Laminated foam sheet and the molded body thereof for vehicle interior
Inventor: NAMURA KIYOYUKI
IPC: B32B7/027
Filed: 1996-12-27
Granted: 2006-11-14
Abstract: A laminated foam sheet for a car interior comprising a foamed core layer of modified polyphenylene ether resin (I) and film layer(s) of thermoplastic resin laminated thereon is disclosed. A glass transition temperature of the thermoplastic resin of the film layer is lower than that of the modified polyphenylene ether resin (I) of the foamed core layer. This makes it possible to produce molded bodies in a simple procedure using the laminated foam sheet. Since the molded bodies produced in accordance with the invention have superior characteristics with respect to heat resistance, rigidity, light weight and heat insulation, they can be advantageously used in car interiors, such as the material for the headliners and door trims. The advantage is an inexpensively produced molded material that is light in weight and very stable, even after prolonged exposure to elevated temperatures such as those that develop in a closed car parked in full sun.

Title: Control of telecommunications networks
Inventor: ANDERSON THOMAS WAYNE
IPC: H04Q3/545
Filed: 1997-01-20
Granted: 2001-04-10
Abstract: Apparatus and method for controlling establishment of telecommunications call connections in a telecommunications network.  The network comprises a plurality of switches each with its own switching processor means, and a plurality of switching processing platforms each comprising at least one call processor. The switches and switching processing platforms are interconnected by a data network.  SS7 signaling messages are received in one of the platforms and a call is assigned to a call processor.  The call processor communicates with one or more switching processor means for controlling establishment of the call.  Call features are processed under the control of the call processor. Advantageously, any call processor can be used for serving any call in the network and can control all legs of a multi-leg connection.  Advantageously, in a large network, the number of platforms may be significantly less than the number of switches which reduces the cost and complexity of administration of the network.

Title: Apparatus with electrode arrays for carrying out chemical, physical or physico-chemical reactions
Inventor: PETHIG RONALD
IPC: C12M1/34
Filed: 1997-03-18
Granted: 2005-09-20
Abstract: Apparatus is described for carrying out chemical, physical or physico-chemical reactions between particles suspended in a liquid medium. The liquid medium is present in channels (1-8, 10, 40, 41, 42, 52, 72) on a generally planar substrate. The liquid medium does not have to flow through the channels, (1-8, 10, 40, 41, 42, 52, 72), but may remain stationary while the particles being reacted move through them. Associated with the channels (1-8, 10, 40, 41, 42, 52, 72) are electrode arrays which enable the particles to be moved, e.g., using dielectrophoresis or travelling wave dielectrophoresis. Complex processing schemes may be achieved using arrays of channels (1-8, 10, 40, 41, 42, 52, 72) and electrodes (20, 21, 22, 36, 56, 71). The apparatus may be manufactured, e.g., using photo lithographic and/or laser machining techniques.

Abstract: The invention relates to treatment of aqueous streams and aqueous systems wi th ozone. The aqueous stream comprises a closed loop system providing transport  from a production locus to a processing locus for a variety of products. The  aqueous stream can contain a challenge soil load and a microbial load. A treatment zone is defined through which the aqueous stream passes. The treatment zone is contacted with a sufficient concentration of ozone to substantially reduce the microbial population and to substantially reduce th e number of microorganisms that can generate slime on the interior of the system. An amount of ozone is added to the aqueous stream in the treatment zone such that once the microbial populations are reduced to a safe level, t he ozone concentration is also reduced to a level substantially safe for contac t with operating personnel and product. Typically, such concentration is less than one part by weight of ozone per million parts by weight of aqueous system, preferably less than 0.5 parts by weight of ozone per million parts of aqueous system. The use of a treatment zone in an aqueous system segregates the ozone from release into areas frequented by operating personnel, sensiti ve materials or product.

Title: Wireless telecommunications system and method for designing same
Inventor: KHANNA SANJEEV
IPC: H04W16/18
Filed: 1999-03-02
Granted: 2002-10-22
Abstract: A method for designing a wireless telecommunications system having a plurality of cells is provided. In one embodiment of such a method, a call demand per cell is estimated, and a channel demand based thereon is determined on a cell-by-cell basis. The cell-by-cell channel demand is used to provide a reasonably tight upper bound on the number of communication channels required to satisfy the system-wide call demand. It is implicit in the procedure for estimating the upper bound that no mutually "interfering" base stations use the same channel (i.e., frequency). "Cliques"  of mutually-interfering base stations or cells are defined. A channel demand is determined for each clique by adding up the channel demand for each cell in the clique.  The greatest channel demand of all cliques determines a "maximum clique demand"  .omega. d. The upper bound on the number of channels required to satisfy the system-wide call demand is given by the expression: X d ~ 17/12 ~ w d when mutually-interfering cells are adjacent cells, and is given by the expression: X d ~ 2 ~ .omega. d min when mutually interfering cells are adjacent cells and next-to-adjacent cells, wherein d min is a minimum channel demand of all cells in the system. Having a reasonably-good estimate of the upper bound on the system-wide channel requirement, a wireless service provider may then seek to obtain or allot a commensurate amount of frequency spectrum to support its system.
