Patent CA-2171374-A1 (CA)
Title: Coriolis mass flowmeter
Inventor: KISHIRO MASAMI
IPC: G01F1/84
Filed: 1996-03-08
Abstract: A Coriolis mass flowmeter includes a housing which contains at least one measuring pipe, a supporting mechanism connected to both ends of the measuring pipe, a vibration generator which gives a vibration to the measuring pipe, at least two sensors for detecting the vibration of the measuring pipe, an inlet conduit which introduces a fluid to be measured into the measuring pipe and an outlet conduit which discharges the fluid out of the measuring pipe. A Coriolis vibration is applied to the measuring pipe which generates a Coriolis force in a fluid flowing in the measuring pipe. The Coriolis force is utilized for the measurement of a flow rate of the fluid. The Coriolis vibration has a frequency higher than a principal natural frequency of the supporting mechanism, i.e., in an inertial control region. The mass flowmeter is of a simple structure and lightweight, minimizes leakage of the energy of vibration to the outside, and has a high mechanical Q value.

Patent CA-2209281-A1 (CA)
Title: Toll free message response
Inventor: HUBER KENNETH M
IPC: H04L12/58
Filed: 1997-06-30
Abstract: A message and billing system and method is provided for transmitting a reply message over a communications network from a called party's message service system to a calling party's message service system. Prior to transmitting a message to a called party, a calling party's message service system prompts the calling party to specify whether a prepaid reply is authorized. Based upon the calling party's response to the prompt, the calling party's message service system generates a message file associated with the message, which includes a prepaid reply field indicating whether a prepaid reply was authorized by the calling party. The message file is transmitted over a communications network to the called party's message service system and the called party's message service system identifies whether a prepaid reply had been authorized by the calling party based upon the prepaid reply field of the message file. Upon the called party's transmission of a reply message to the calling party's original message, the called party's message service system generates a reply message detail record having a prepaid reply field indicating whether the calling party had authorized a prepaid reply. When the prepaid reply field of the reply message detail record indicates that the calling party authorized a prepaid reply, the calling party is charged a fee for the transmission of the reply message. Alternatively, when the prepaid reply field of the reply message detail record indicates that the calling party had not authorized a prepaid reply, the called party is charged a fee for the transmission of the reply message.
