Patent EP-0580326-A1 (EP)
Inventor: BLADES FREDERICK K
IPC: G01R27/22
Filed: 1993-07-08
Abstract: Improved circuits for measuring the conductivity of a solution confined between two electrodes in a cell compensate for series capacitance and parallel capacitance between the electrodes. A bipolar square-wave signal is applied to the cell. In one embodiment, the current through the cell is measured by an op-amp in current-to-voltage converter configuration. A feedback resistance employed with the op-amp in a feedback loop is controlled to a low value to ensure that the parallel capacitance is fully charged during an initial portion of each half-cycle of the drive signal. The feedback resistance is then selected so that the gain of the feedback loop is responsive to the range of the resistivity of the solution, and the measurement is made. The period of the bipolar signal is selected responsive to the selected loop gain, to ensure that a filter capacitor across the op-amp is fully charged, and to limit distortion caused by the series capacitance. More particularly, the rate of charge of the series capacitance is proportional to the solution resistance; by varying the period of the drive signal in accordance with the solution resistance, the distortion introduced by the series capacitance remains negligible. 
     In a further embodiment, charge proportional to the current through the cell is integrated across the op-amp, and the rate of charge is measured by measuring the time required to integrate the current to a predetermined level, and used to determine the resistivity of the solution. In this embodiment, the parallel capacitance is fully charged before each integration period begins. The voltage developed across the series capacitance is constant and can be compensated mathematically.

Abstract: The present invention relates to a system for determining at least one control parameter for vehicular traffic. The system according to the invention includes, firstly, a pulsed radar placed high up on the side of the lanes to be monitored, the radar emitting pulses of frequency f0 and of width  tau  according to a radiation pattern which is narrow in bearing, and sufficiently wide in elevation to cover all the lanes to be monitored, and inclined in elevation and bearing such that at least one range bin (7) of the radar is included in a lane. The echo signals received by the radar are then processed by a signal processing module and a parameter extraction module. The invention is particularly relevant to the automobile field for determining the number of vehicles passing through the lanes, their speed, their length etc. The advantage of such a system by comparison with the prior art is that it allows simultaneous control of several lanes of traffic. <IMAGE>

IPC: B01D29/66
Filed: 1994-03-01
Abstract: In the production of plastics granules, a granulation water tank equipped with screening devices for fines separation is required in order to prepare the cooling water for reuse. The aim of the invention is a space-saving design of the water tank and prevention of damage to the fines screen when a stream of water charged with starting granules and/or agglomerates is fed to the tank. This is achieved by the inlet opening (2) for the stream of water being arranged on the tank (1). Arranged underneath the inlet opening (2) is a screen (4) with an adjoining granules transporting container (6), as the first level, and arranged at a distance underneath is a run-in plate (5) with adjoining screening device (7), as the second level, passing through the water tank (1). Each level is assigned an outlet (9, 15) with a common chute (17). <IMAGE>

Abstract: A description is given of a method and a device (1) for providing (replicating) a patterned resyntetic resin relief (37) on the surface (25) of a glass substrate (27). For this purpose, a UV-curable acrylate lacquer (33) is applied to the surface (25), after which a transparent mould (3) having a relief (13) is rolled-off over the surface (25). By means of a UV light source (17) and an elliptic mirror (21), the lacquer is cured at the location of the focal line (23), thereby forming said relief (37). The relief (13) of the mould (3) is replicated on the glass substrate (27).
