Title: Comb filter
Inventor: DRAXELMAYR DIETER
IPC: H03H17/02
Filed: 1998-08-21
Abstract: The invention relates to a comb filter consisting of integrators (I1, I2, I3) connected in series, to which a digital data flow with high scanning rate is fed in order to supply a digital data flow with a lower scanning rate. The most significant bits of the digital data flow are reset in the first and second integrators (I1, I2), whereby the resetting of the bits in the first integrator (I1) is stored in a counter (Z). The count of the counter (Z) is fed to the most significant bits of the last integrator (I3) during reset time.

Title: Improved wheel hub for longer wheel life
Inventor: TIMM F GUY
IPC: B24D7/16
Filed: 1997-11-25
Abstract: A wheel hub is provided for use in combination with conventional depressed center grinding wheels. The hub includes a generally cylindrical aperture bushing. A disc shaped flange extends radially from a medial portion of the bushing and terminates at a peripheral lip. The bushing is adapted to extend through a central bore of the wheel so that the lip engages the backing face of the wheel proximate an outermost circumference of the depressed center. A grinding face end of the bushing is flangeable radially outward to engage the front grinding face of the wheel and mechanically capture the wheel between the grinding face end and the flange. The flange, lip and backing face form a cavity into which epoxy resin is placed to chemically bond the hub to the wheel. The combination of mechanical fastening and chemical bonding adequately secures the hub to the wheel, nominally without requiring the flange to extend over the stub. The present invention thus advantageously enables the wheel to be ground nominally to the stub, to provide improved wheel utilization.

Title: Bead inductor and method of manufacturing same
Inventor: SUGITANI MASAMI
IPC: H01F27/29
Filed: 1999-06-22
Abstract: A method for manufacturing a bead inductor includes steps of forming a molded body of a resin or a rubber including a powdered magnetic substance, with a conductor coil formed by winding a metallic wire coated for insulation embedded therein; cutting both end portions of the molded body so as to expose end portions of the conductor coil; and attaching external terminals to exposed end portions of the conductor coil so as to be electrically connected. In order to increase reliability of connection between the conductor coil and external terminals, both end portions of the conductor coil prior to the forming step are immersed into a solder bath so as to include the cutting regions of both end portions of the molded body therein such that soldered portions are formed by removing insulation coating on both end portions of the conductor coil. A bead inductor is produced by using this conductor coil.

Patent CA-2276983-A1 (CA)
Inventor: COX NEIL B
IPC: H04L12/24
Filed: 1999-07-05
Abstract: The present invention allows end user enterprises to achieve specific objectives in the management and enforcement of policies related to the use of telecommunications services in a telecommunications network. It was conceived for use in connection with traditional telephone networks that carry voice, facsimile or voice-band-data (VBD) traffic, though it is not necessarily limited to such networks. It involves active measurement of the properties of traffic on a communications channel, and the use of such knowledge in the conditional performance of prescribed actions based on the traffic properties. The prescribed actions have the effect of blocking usage of telecommunications service by traffic with specified properties under specified conditions. The prescribed actions can be disabled to make it operative for collection of data on the degree of compliance with service usage policies. The prescribed actions can also involve selecting or configuring a downstream telecommunications service for carriage of traffic with the observed traffic properties. Signal processing is used to measure the properties of traffic present on a channel at a given point in time, and prescribed actions are conditionally performed based on said traffic properties when service usage policies are determined to have been violated. Embodiments of the invention can be used to provide a phone service control platform (Phonewall) for establishing separate telecommunications service access policies for voice, facsimile and VBD, and for actively performing the necessary monitoring, policing and record generation to ensure compliance with these policies. This provides a superior means of minimizing the threat of unauthorized modems to computer security by blocking modem use on lines that do not have specific devices and protocols for fraud control. The threat of long distance fraud through generation of a "flash-hook" from a modem can be mitigated by declaring all lines that are attached to authorized modems to be "modem-only" lines: illegal voice calls are terminated as soon as the conversation starts. Declaring all lines connected to fax machines to be "fax-only" lines serves to block the threat of unauthorized long distance calls through facsimile machines. Finally, the categorization of traffic as voice, facsimile and VBD allows for strategic selection of telecommunications services to best match the intended usage.

Title: Method and apparatus for removing and suppressing coke formation during pyrolysis
Inventor: GANDMAN ZALMAN
IPC: C10G9/16
Filed: 1998-06-05
Abstract: A method and apparatus for decoking and suppressing coke formation during pyrolysis has been discovered that does not require complete shut down of the pyrolyses furnace. For the decoking step, the hydrocarbon feed is cut off to one or more coils for usually less than about three hours during which a decoking additive is added to the steam flow in that coil. This additive is comprised of an aqueous solution of a group IA metal salt and a group IIA  metal salt and catalyzes the coke removal. The hydrocarbon feed continues in the other coils during this procedure. After decoking, a suppression additive also comprising group IA and IIA metals is added to the steam and hydrocarbon feed. This suppression additive will melt onto the inner surfaces of the pyrolysis furnace coils, coating the coils with a glass layer which inhibits coke formation. The apparatus of the invention is particularly suited for introducing the additives of the invention into the steam flow at a desired drop size without touching the sides of the coil.
Patent CA-2293921-A1 (CA)
Title: Colorimeter apparatus and related process
Inventor: SANDLIN JOHNNY MICHAEL
IPC: G01J3/46
Filed: 1999-12-31
Abstract: The disclosure of this invention relates to colorimeters and a process for operating a colorimeter. The colorimeter of the disclosure is controlled by a microprocessor which evaluates a predetermined radiation absorption curve for each sample. This is to be contrasted with the prior art wherein the test on a given sample evaluates only radiation absorption concentration points which are evaluated by the microprocessor. The colorimeter gives more accurate readings as a result of the fact that an absorption curve and its parameters are evaluated for each sample. The colorimeter uses multiple LEDs as a radiation source. The microprocessor further controls other functions of the colorimeter. A separate microprocessor may be used to control these other functions. The colorimeter and process of this invention are also useful in the analysis of samples for turbidity.
