Patent CA-2193620-A1 (CA)
Inventor: MOTTIER BRADLEY D
IPC: F02P1/08
Filed: 1995-06-16
Abstract: An ignition system is provided for an internal combustion engine (67) that operates in two modes. In a first mode, the timing of the spark event is under electronic control. In a second mode, the timing of the spark event is fixed and synchronized to the mechanical rotation of the crankshaft (65) of the engine. Under normal operating conditions, the timing of the spark event is electronically controlled. If the electrical system of the engine malfunctions, the ignition system defaults to the second mode in which ignition timing is mechanically controlled.

Title: Method for billing multiple services on a single account
Inventor: FRIEDES ALBERT
IPC: H04M15/00
Filed: 1997-09-24
Abstract: Aggregated billing for calls originating from separate telephone stations (12-20) may be obtained by accessing a segmentation directory (54) upon the receipt of the call at an originating switch (40 1) within a telecommunications network. The segmentation directory contains a table that associates each of a plurality of common account numbers with telephone stations having telephone numbers assigned to the same subscriber. The common account associated by the segmentation directory for an incoming call is used in creation of the billing record for charges associated with the call. The charges contained in the billing records for calls associated with the common account number can be combined to yield an aggregate bill.
Patent CA-2216848-A1 (CA)
Inventor: RAVOT JEAN-FRANCOIS
IPC: H01F27/28
Filed: 1997-09-26
Abstract: In the  case  of  a transformer,  comprising an iron core  (1), a low-voltage winding  (2)  and a high-voltage winding  (15),  the two of which are arranged coaxially on the iron core  (1),  the end edge regions (3)  of the windings  (2,15)  each have three disks or disk windings (8,13,14), which disks or disk windings (8, 13, 14)  each have,  toward the  iron yoke  18,  a radial winding width  (12)  which is  smaller in steps than  the  windings  (2,15)  themselves.  This  measure homogenizes  the  electrostatic  fields  which occur  in operation,  so that a reduction in the internal radius (4)  of the low-voltage winding  (2)  which is oriented toward  the  iron  core  (1)  and  a  reduction in  the insulation  separation  (17)  between  the  low-voltage winding (2)  and the high-voltage winding (15)  is made possible.  As  a consequence of  these reductions,  the geometrical dimensions can be considerably reduced, and considerable savings can be made,  with regard to all the materials used. There is no longer any need to use protective rings,  a shielding ring or a guide insert for electrostatic field control.
Patent CA-2216968-A1 (CA)
Title: Self-adjusting sensor
Inventor: LASKOWSKI EDWARD L
IPC: G01B5/00
Filed: 1996-04-02
Abstract: A sensing device comprised of a sensing circuit (92) which changes its operating characteristics when an object comes near it. The sensing circuit (92) produces a change in output voltage proportional to the change in relative distance between the sensing circuit and an object. The actual output voltage is a functional of both target distance and control circuit input voltage. The control circuit (96) includes a comparator (102) for comparing the steady state output voltage to a reference voltage and adjustment system (104) for adjusting the input voltage to change the steady state output voltage such that the steady state output voltage approximately equals the reference voltage. The control circuit (96) reacts only to reductions in the steady state output voltage, indicative of mechanical wear, and not to increases in output voltage, indicative of currency thickness measurement.

Patent CA-2220790-A1 (CA)
Title: Automatic learning of network routing using random routes
Inventor: GALLAGHER DONALD D
IPC: H04M7/00
Filed: 1997-11-12
Abstract: Routing selected telecommunication calls to individual destination switch nodes by each switch node of a distributed telecommunication switching system over randomly selected telecommunication links not marked in an internal routing table of each switch node as being routes to those individual destination switch nodes. When each telecommunication call is established, a return message from the destination switch node provides routing information back to the originating switch node. Each originating switch node updates its routing table based on the results of the routing information returned when the random route is established. A random route is selected every predefined number of calls to eachdestination switch node.

Title: Retrovirus vectors derived from avian sarcoma leukosis viruses permitting transfer of genes into mammalian cells and therapeutic uses thereof
Inventor: BARSOV EUGENE
IPC: C07K14/15
Filed: 1996-05-22
Abstract: Recombinant avian sarcoma leukosis virus (ASLV)-derived retrovirus vectors having an expanded host range are described. The host range is expanded by the replacement of the ASLV  envelope gene by an envelope gene from a virus capable of infecting both mammalian and avian cells.      The resulting recombinant ASLV-derived retroviral vectors can replicate efficiently in avian cells, infect both avian and mammalian cells in high titer, and are replication-defective in mammalian cells. Thus, they are quite safe and advantageous for use in gene therapy and vaccines.
Patent CA-2221952-A1 (CA)
Title: An improved messaging platform process
Inventor: HUBER KENNETH MERVIN
IPC: H04M3/53
Filed: 1997-11-24
Abstract: Numerous benefits are realized by allowing messaging platforms to receive and act on information packages that include one or more Execution Instruction Sets (EISs), where the EIS is executed as specified. Execution of the included EISs provides vastly enhanced capabilities to the messaging platform, such as controlling when an EIS is executed, from where necessary data is obtained for the execution of the EIS, what kinds of executions are permitted, who will be the recipients of the content portion of platform, what that contentwill be, etc. Increasing the interaction complexity a step further, the EIS permits creation of an interactive session with the recipient that makes the message more effective. A still additional capability is the establishment of a communicationpath from the messaging platform. This may be in the form of a message that is sent by the messaging platform, or a connection that is established between the recipient and some other party.

Title: Use of muteins of wild-type cytokines as immunogens
Inventor: CILIBERTO GENNARO
IPC: A61P37/04
Filed: 1996-08-22
Abstract: These are pharmaceutical compounds used to treat or prevent diseases caused by the over-production of a specific wild-type cytokine, characterised by the fact that they contain as an active principle at least one mutant of that wild-type cytokine. In its widest scope the invention consists in the use of muteins of a specific wild-type cytokine, that are also receptor antagonists of the latter, as immunogens to elicit antibodies directed against this wild-type cytokine and capable of neutralising it in those diesases caused by its excessive production. Figure 4 shows that antibodies developed in NSF/hIL-6 transgenic mice immunised with a human interleukin 6 mutein are capable of recognising wild-type interleukin 6 and of neutralising its biological activity.
