Patent CA-1300402-C (CA)
Title: Apparatus and method for continuously measuring mass flow
Inventor: MIZERAK DENNIS S
IPC: G01F1/84
Filed: 1987-08-19
Granted: 1992-05-12
Abstract: ABSTRACT OF THE DISCLOSURE             An apparatus and method for measuring mass flow rate which utilizes a pair of parallel conduits having fixed ends.  A driving mechanism is connected between the conduits near their mid-point for applying transverse oscillations to the conduits at a selected frequency.  The fluid whose mass flow rate is to be measured is divided roughly equally and supplied through the parallel conduits.  A motion sensor upstreamof the driving mechanism and another one downstream of the driving mechanism produce signals which have the same frequency as the driving frequency but which lead or lag the driving frequency with regard to phase.  This difference in phase is a measurement of mass flow rate.  The apparatus can be constructed to self compensate for changes in temperature and/or thermal gradients.

Title: Electronic clinical thermometer
Inventor: YAMAGUCHI KEIJI
IPC: G01K7/42
Filed: 1987-11-16
Granted: 1992-01-14
Abstract: ABSTRACT OF THE DISCLOSURE   An electronic clinical thermometer for predicting a sensed temperature that will prevail at a future time is equipped with a predetermined predictive functional formula in which values of predetermined coefficient parameters for superimposing said prediction function on a sensed temperature curve are undetermined.  Temperature data indicative of sensed body temperature are stored in correlation with elapsed time from the start of measurement, and plural items of the temperature data are read out by a predetermined method as measurement proceeds.  By performing regression analysis based on a plurality of the predictive functional formulae, or by solving simultaneous equations constituted by the plurality of predictive functional formulae, in which the sensed temperature data that have been read serve as purposive variables and functions of time data related to the temperature data serve as explicative variables, the values of the coefficient parameters are set.  Prediction processing is executed to calculate sensed temperature that will prevail at a future time in accordance with the predictive functional formula specified by the set values of the coefficient parameters.

Abstract: ABSTRACT OF THE DISCLOSURE              A  converter  for  interconnecting  two electric networks to transmit electric power from one network to the other, each network being coupled to a respective power generator station.   The converter, having an AC side and a DC side, includes a bridge of semiconductor switches with gate turn-off capability coupled to a  control  system to produce a bridge voltage  waveform  having  a  fundamental  Fourier component at the frequency of the electric network coupled to the AC side of the converter.  The control system includes three inputs for receiving reference signals  allowing  to   control  the  frequency,  the amplitude and the phase angle of the  fundamental Fourier component with respect to the alternating voltage of the network coupled to the AC side of the converter.   Through appropriate feedback loops, the converter may be used to maintain at a predetermined level the power flowing therethrough or to keep at a preset value the voltage across the DC terminals of the converter and,  in both cases,  to maintain the frequency synchronism between the fundamental Fourier component and the alternating voltage of the network coupled to the DC side of the converter.

Title: Container and dispensing system for liquid chemicals
Inventor: OSGAR MICHAEL L
IPC: B65D25/14
Filed: 1989-02-15
Granted: 1999-01-26
Abstract: A container for storage, transport and dispensing of liquid chemicals uses a collapsable thin film pouch which is sealed to a fitment and is positioned within a bottle or overpack.  A retainer and cap hold the pouch and fitment in place within the bottle.  The cap provides an inner seal and an outer seal which remain intact during shipping and storage.  In use, the outer seal is removed and the container is connected to either a manual or an automated dispensing system which includes a valve probe which breaks the inner seal.  In the manual system the bottle is inverted so that flow of liquid from the pouch is gravity assisted. In the automated system, the container is placed within a pressure vessel and air pressure is applied both to the outside of the bottle and also to the inside of the bottle to assist in collapsing the pouch and forcing the liquid out of the pouch.  When empty, the container is removed from the manual or automated dispensing system and the cap and retainer are removed to allow removal and disposal of the pouch and fitment.

Abstract: An electronic timing apparatus for determining precisely when vehicles pass over a particular line on road, particularly a race track (20), has a series of separate loop antennas (26), arranged in closely ad adjacent relationship one to another across the width of the track. Each vehicle (82, 82) is fitted with a transmitter (28) for transmitting a unique identifying signal which is received by a loop antenna as the vehicle pass over the line.  The width (x) of the antenna loops relative to the width of the vehicles is such that only one transmitter (28) can pass over a particular loop at the one time whereby when two or more vehicles cross the line simultaneously,  signals from the  respective  transmitters  are received in different antennas.  A respective receiver module (27) is connected to each antenna loop and processes the identifying signal which is then fed to a micro-controller (43) which calculates the time at which the particular vehicle crossed the line.  A supervisory computer (24) collates and provides a database of timing information.
