Patent CA-2044243-A1 (CA)
Title: Shaft crack detection method
Inventor: MILLER WILLIAM H
IPC: G01M99/00
Filed: 1990-01-18
Abstract: The presence of a crack in a shaft (42) is determined by comparing natural frequencies of the shaft  (42)  with an analytical model (62).  From a multistation analytical model (62) of an uncracked shaft (42), natural frequencies and associated mode shapes are derived.  A suspected axial location of a crack is defined, and a natural frequency is selected which has an associated mode shape exhibiting maximum deflection at the suspected axial location of the crack.  The analytical model (62) is modified to include a representation of an asymmetric crack at the suspected crack location, and the predicted split and downward shift of the natural frequency is calculated from the modified model.   The shaft  (42)  is  subjected to a radial excitation force, and vibrational response measurements are taken with an accelerometer (76).  A fast Fourier transform analyzer (78) derives a frequency response function from the measurements which indicate the natural frequencies of the shaft (42).  These natural  frequencies  are  compared  with  those  predicted  to determine the presence of a crack.
Patent CA-2044874-A1 (CA)
Title: Network monitoring device and system
Inventor: PHAAL PETER
IPC: H04L12/56
Filed: 1991-06-18
Abstract: The network monitoring device is provided for monitoring the activity on a network carrying message packets each of which contains source and destination addresses. The monitoring device comprises a network interface for sending and receiving message packets carried on the network, and processing means for collecting and processing data from the packets received by the network interface. In order to minimize processor memory requirements for the monitoring device, only randomly selected packets detected by the network interface are processed by the processing means of the device.      Preferably, the monitoring device is further simplified by providing a central measurement station to analyze data collected from the randomly sampled packets. As a result, the only processing required to be done by the monitoring device is the construction of collected-data packets for transmission to the central measurement station. A network monitoring system can advantageously be provided by using a number of such monitoring devices each associated with a respective logical segment of the network and each forwarding collected-data packets to a central measurement station.

Title: Measuring device and process for determining the level in fluid containers, preferably for tank installations, and use of a sound waveguide
Inventor: DAGES JOHANNES
IPC: G01F23/28
Filed: 1990-08-22
Abstract: Abstract In a level measuring device for containers (20) filled with fluid (10), preferably tanks in tank installations, the fill level height h is determined from the transit time of ultrasound pulses which are emitted by first sound pulse transmitters (S1) along a main measuring path (8) extending from the bottom region of the tank (20) to the fluid surface (9, 9') and reflected from the fluid surface (9, 9') to first sound pulse receivers (S1).  Means are provided in the form of temperature sensors (1, 15,  16)  for finding the temperature distribution throughout the fill level height h.  Processing the measurements provides a mean temperature TM in the fluid volume.  In addition to the main measuring path (8) there is a reference path (11) in the fluid volume, with second sound pulse transmitters and receivers (S2) and a reference temperature sensor (14) to measure a reference temperature TRef.  The reference path makes it possible to find the sound velocity v*(TRef) in the fluid volume at the reference temperature TRef from the measured difference in transit time, so that a temperature-corrected sound velocity v(T) in the fluid volume: v(T) = v*(TRef)[1+Kk?.DELTA.T), and thus a temperature-corrected fill level height h(T) = v(T)?tH, are found, in which .DELTA.T = TM-TRef , and Kk is a medium dependent correction factor.  The subject of the invention also includes a process for determining the fill level and an advantageous use of a measuring tube (24) comprising a first and a second sound waveguide (4,5).
