Patent FR-2666598-A1 (FR)
Title: Process for the separation, especially for sorting or fractionating a suspension of paper pulp
Inventor: HERBERT HOLIK
IPC: D21D5/02
Filed: 1991-09-09
Abstract: The separation process applies especially to the treatment of a suspension (4) of paper pulp based on recycled paper, containing impurities (6) such as fragments of plastics. The process takes place in an annular chamber (1) between at least one screening surface (2) with exit passages (3) for the fibres and a wall (14). The pulp suspension is driven by rotary means which pick up all along the screening surface (2) the material (9) retained by the orifices (3) and move it away from the wall (2) while throwing it back radially into the stream of the suspension (4) circulating in the annular chamber, so as to mix it intimately with the suspension (4) while preventing mixing in the axial direction as much as possible. The thickening of the suspension and the concentration of the impurities are thus transferred into the lower zone, where a water injection is used to dilute the suspension to ensure good progress of the process and to separate the impurities from the fibres by washing. The rotary means impart a swirling motion to the suspension, causing a continuous mixing, in radial direction, of the rejected material (9) with the suspension (4).

Title: Functional monitoring of electric vehicle propulsion system - using actual instantaneous system power input which is compared with theoretical value under same conditions to detect malfunction
Inventor: CHRISTIAN BARREAU
IPC: B60L3/12
Filed: 1992-07-22
Abstract: Battery (1) voltage (U) and current (I) measurements, discounting non-propulsive loads, give the actual instantaneous power. The theoretical power is the sum of inverter (2) and induction motor (3) losses and the power (set torque x angular velocity) delivered to the final drive (4). Set torque is determined by the driver through accelerator (8) and brake (9) pedal positions, transmitted by sensors (6,7) to the controller (5). Losses, tabulated from bench tests as functions of torque and speed, are obtained from memories by a calculating unit in the controller, which uses them, with operational parameters to compare the two power values. An excessive discrepancy initiates an alarm. ADVANTAGE - Standard vehicle instrumentation provides all measurements required.
