Patent CA-2083308-C (CA)
Title: Power factor matching in an ac power meter
Inventor: VOISINE JOHN T
IPC: G01R21/133
Filed: 1992-11-19
Granted: 1998-08-18
Abstract: A solid-state AC energy consumption meter includes an array of AC signal transducers which provide voltage and current signals to a watt transducer chip. The watt transducer chip operates on the multi-phase voltage and current signals to produce AC energy consumption data which is fed to a register for visual display.  In one aspect of the invention, a calibrating resistive component is placed in series with the input to the primary coil of the potential transformer for each phase.  The value of the resistive component is calibrated to produce an appropriate change in the phase angle difference between the potential transformer secondary voltage and current transformer secondary current. More particularly, the addition of the resistance of the primary of the potential transformer provides the necessary amount of phase lead to the potential transformer to account for this phase error difference.

Abstract: A sheet restraint for a sheet shipping rack includes a first elongated tube rotatably mounted on a second elongated tube.  The second tube has U-shaped member secured to each end to capture the first tube on the second tube while allowing the first member to rotate relative to the second member.  A resilient elongated sheet engaging member is secured to the first member.  A pair of spaced pins are mounted on the first member and engageable with the U-shaped member to limit rotation of the first member about the second member so that the rotational path of the sheet engaging member and first tube is limited.  The engaging members on the second tube are slideable mounted to spaced standards at the front of a rack.  In this manner the front restraint moves toward the base into engagement with the outermost sheet of a stack of sheets on the rack to maintain the sheets as an integral pack.  During shipment, the movement of the sheets and rack by the transportation forces and any space resulting from such movement is taken up by the front restraints as it moves downwardly toward the base. To unload the sheets from the rack the front restraint is urged upward away from the base and removable from the standards at the front of the rack.

Title: Mediation of open advanced intelligent network interface for public switched telephone network
Inventor: WEISSER FRANK J JR
IPC: H04M3/42
Filed: 1994-06-27
Granted: 2000-04-25
Abstract: A method of mediating message traffic across interfaces open to third parties in an Advanced Intelligent Network for a switched telephone system is disclosed. Network utilization is monitored by maintaining message counts at the open interfaces and rejecting messages or terminating access via the interface when an excessive rate of traffic is detected. Access to data bases stored in service control points is used to determine if the sender indentified in the contents of the message is the same as the entity authorized to use the physical port upon which the message was received. Also, customer records in the service control point are tested to determine if the sender of the records in sage is authorized to affect the call progress of an affected customer directory number identified in the message. Upon termination of the message traffic across a port, a defaut application is activated so that other network elements do not have to rely on timeouts to continue processing of calls.
