Title: Measurement probe with analog-to-digital converter
Inventor: LAROCCA BRIAN
IPC: H03M1/52
Filed: 1995-04-07
Abstract: A measuring probe measures a parameter with a sensor. The sensor provides a sensor output signal related to a measured value. An amplifier section receives the sensor output signal and provides an amplifier output signal. An integrator has an input and an integrator output related to an integration of the input. Switching circuitry receives the amplifier output signal and a reference signal and has an output to the integrator. Controller circuitry coupled to the switching circuitry connects the amplifier output to the integrator input during a sampling time, and the reference signal to the integrator input during a conversion time. The conversion time is related to the sensor output signal and is measured to obtain a digital representation of the sensor output.

Patent CA-2190868-A1 (CA)
Title: Improved wet scrubbing method and apparatus for removing sulfur oxides from combustion effluents
Inventor: KLINGSPOR JONAS S
IPC: B01F33/40
Filed: 1995-06-07
Abstract: Sulfur oxides (SOx) are scrubbed from combustion effluents with aqueous limestone slurries single-loop, open-tower countercurrent limestone wet scrubbers. Effluent flow rates are greatly increased while L/G values and reaction tank (150) residence times are decreased. Improved entrainment eliminator design, nozzle (112) placement and spacing, and the use of a hydrocyclone (181) to separate and recycle smaller particles of limestone from the byproduct gypsum, facilitate these advantages. Limestone is reduced to very fine particles, e.g. about 8µ or less with more than 99 % of the particle by weight less than 44µ, and introduced into a scrubbing slurry which is contacted with SOx-laden effluent. Reactivity of the scrubbing slurry is maintained, even at reduced pH, by continuously operating a hydrocyclone to assure a molar ratio of calcium-containing to sulfur-containing compounds of greater than about 1.3 to 1 while keeping both a low chloride and low non-reactive solids content. The hydrocyclone removes large particles of calcium sulfate and provides a recycle stream (184) of fine calcium carbonate and non-reactive solids which is bled off as necessary to maintain both the desired low chloride and non-reactive solids levels.

Title: Process and device for common regulation of electric motors driving wheels of a vehicle
Inventor: BOSSONEY LUC
IPC: B60L3/10
Filed: 1997-01-29
Abstract: An electric vehicle drive system has several asynchronous electrical machines (11,12) each coupled to drive wheel (13,14), a polyphase supply unit (2) and a regulator (6) which uses a reference signal (SR) which represents the speed of one of the wheels. In traction mode each wheel is continually monitored for slip. If one wheel slips and at least another doesn't a speed signal (NM1,NM2) is selected for the non slipping drive wheel which turns the quickest, or if all the wheels slip a change signal (NF1) is used to produce the reference signal (SR). This first change signal represents the speed of a drive wheel immediately before it starts to slip. In the braking mode, where the electrical machines are driven by the wheels each wheel is continually monitored for locking. In the selection stage if at least one wheel is locked a speed signal is selected (NM1,NM2) which corresponds to the drive wheel which turns the quickest. If all the wheels are locked a second change signal (NF1) is used to produce a reference signal (SR) which represents the speed of a drive wheel immediately before locking.
