Patent CA-2285156-C (CA)
Title: A constant current termination for cable locating tones
Inventor: VOKEY DAVID E
IPC: G01R31/08
Filed: 1999-10-06
Granted: 2005-04-12
Abstract: A constant current termination is provided for cable locating tones on communication and control cables that may be buried or placed in underground duct structures. The constant current termination limits the current on each branch of the cable to that required for cable location, thus ensuring that branches furthest from the tone source have adequate current for location purposes. The termination is the same for each branch, regardless of its position along the cable system. This eliminates the need to calibrate and recalibrate termination distances for a cable on installation and when branches are added. It also allows the location of damaged cables where the tone signal strength on a damaged brat is less than that for which the termination was designed.
Patent CA-2292111-C (CA)
Title: Isocyanate-based polymer foam and process for production thereof
Inventor: DOLGOPOLSKY INNA
IPC: C08L75/04
Filed: 1999-12-13
Granted: 2010-07-20
Abstract: An isocyanate-based polymer foam comprising an isocyanate-based polymer foam matrix having disposed therein a particulate material having an enthalpy of endothermic phase transition of at least about 50 J/g. A process for producing the foam is also described. During the process, the particulate material acts as a heat sink and will undergo an endothermic phase change by absorbing a significant portion of the heat of reaction liberated during the process. This improves the safety of the process by lowering the maximum exotherm experienced by the foam and/or improves product properties.

Patent CA-2294615-C (CA)
Inventor: DAVISON RICHARD R
IPC: C12P7/40
Filed: 1998-06-12
Granted: 2009-07-14
Abstract: On peut concentrer des solutions diluées de sels de fermentation par extraction d'eau au moyen d'amines secondaires et tertiaires peu miscibles présentant un poids moléculaire bas, par exemple triéthylamine (TEA), diisopropylamine (DIA), N,N-diéthylméthylamine (DEMA) et leurs mélanges. A 30  DEG C-55  DEG C, ce qui correspond à des températures de fermentation typiques, ces amines ou leurs mélanges peuvent extraire des quantités importantes d'eau depuis des solutions aqueuses diluées contenant des sels de fermentation. On peut, de ce fait, concentrer des solutions diluées de sels de fermentation par suppression sélective d'eau. A ces températures basses, la phase amine contient 20-35 % d'eau et une quantité très diminuée de sel de fermentation. Quand on élève la température, la phase aqueuse sort de l'amine, ce qui permet de recycler l'amine et de l'utiliser de nouveau afin d'extraire une quantité supplémentaire d'eau. Grâce à ce procédé, on peut supprimer 82,5 % d'eau depuis une solution diluée à 3 % au moyen d'une extraction classique à contre-courant à étapes multiples et, par conséquent, obtenir une solution de sel de fermentation concentrée à 15 %.
Patent CA-2300455-C (CA)

IPC: G01R31/36
Filed: 2000-03-10
Granted: 2004-01-06
Abstract: By finding a voltage difference .DELTA.V between the maximum value and the minimum value of voltage of each cell constituting a battery set and then combining the voltage difference .DELTA.V with current I passing through the battery set into a value pair and store a plurality of the value pairs, the relationship between the voltage difference .DELTA.V and the current I is a relation represented by a straight line with the slope .DELTA.R thereof corresponding to an internal-resistance difference. Therefore, fault in the battery set can be determined from the magnitude of the slope .DELTA.R computed by a least- squares method. Fault determination for a battery set is made more accurate because variations in electromotive force caused by charge-and-discharge patterns and by changes in temperature are canceled when the voltage difference .DELTA.V is determined.

Title: Schematic generator for use in a process control network having distributed control functions
Inventor: BROWN LARRY K
IPC: G05B17/02
Filed: 1998-10-21
Granted: 2007-03-20
Abstract: A schematic generator for use in a process control network, in which control functions are implemented by field devices interconnected at various and distributed locations on a bus, polls each of the field devices to retrieve information pertaining to the identify of the device, the identity of the control functions associated with the device, the manner in which the device communicates with other devices with respect to each of the control functions associated with that device, the timing associated with the execution of each of the control functions of that device and the timing of the communication activities associated with each of the control functions of that device. The schematic generator then analyses the retrieved data to identify the manner in which the devices are physically connected on the bus and the manner in which the different control functions are interconnected over the bus to perform process control loops within the process control network. Thereafter, the schematic generator creates one or more schematics, such a maintenance schematic illustrating the physical layout of the field devices in the process control network, a control loop schematic illustrating the interconnections between functions within one or more of the devices that form a control loop, and a timing schematic illustrating the timing of or the amount of communications occurring on the bus.
