Title: Device for detecting faults in electrical insulation for a current-carrying installation
Inventor: PHILIPPE FESAIX
IPC: G01R31/02
Filed: 1990-03-16
Abstract: A portable device for fault detection in the electrical insulation of an electrical or electronic installation powered by a distribution network in which the neutral is connected directly to earth (known as the TT mode) equipped with a quick-trip protective circuit breaker (4). The device (1) connected to the network comprises an isolation transformer (5) coupled to a leakage current detector circuit (6). The installation to be monitored (2), connected to the device (1), is equipped with an insulated conductor (7) which is connected to an electrical earth (8) of the device (1) through a resistor (9). When an insulation fault occurs, a leakage current flows in the conductor (7) and then in the resistor (9); the voltage across the terminals of this resistor is filtered and compared with a threshold value in a comparator (11) and then triggers a luminous alarm (13) via a relay (14) if this voltage is greater than the threshold value. Application to the detection and location of faults in the insulation of an installation, of apparatus or of a component in apparatus (e.g. an electronic card) connected to a distribution network in TT mode.

Title: Method and equipment for managing calls in a broadcast-type radiotelephony network
Inventor: DANIEL GENIN
IPC: H04W68/00
Filed: 1991-07-30
Abstract: The method consists, for calling mobile units from the management centre, in: having each of the stations send, over a predetermined call channel which is recognisable by a specific call modulation, a call signal including identifiers of the mobile units requested; having the call channel analysed by each mobile unit, these mobile units being set up in advance on this call channel; with each received identifier, having the mobile unit compare this identifier with that specific to the mobile unit in question; and, in the event of a matching comparison, having the mobile unit acknowledge the call, in such a way as to allow the radiotelephony communication to be set up. According to the invention, this method is characterised in that: the call channel of each station is an essentially fixed channel; during the analysis step, the mobile units remain on the frequency of the call channel as long as they recognise the said specific call modulation on it; and the mobile unit acknowledges the call by searching, among the channels of the station other than the call channel, for a free channel which is recognisable by a specific availability modulation, and by sending, on this free channel, an acknowledgement signal, in such a way as to allow setting up of the radiotelephony communication on this free channel.

Title: Process and device for automatic regeneration of a demineralisation station
Inventor: EUGENE SADON PIERRE LOUIS
IPC: C02F1/42
Filed: 1991-11-22
Abstract: Process and device for automatic regeneration of a double battery (G, D) for the demineralisation of water using ion exchange resins. This process consists in employing a fraction of the water treated by one of the batteries (G) for diluting and entraining the acidic and basic regenerants, respectively, from the tanks (H) and (OH) on the exchangers (A2, C2) of the other battery (D). The flow rates of the water pipelines (2 and 2'), on the one hand, and (3) and (4), on the other hand, are regulated to make the end of a production cycle of one battery (G) and the end of rinsing-regeneration of the other battery (D) coincide. At this stage, merely by reversing the 5-way manual valves (V1 - V2 - V3 and V4), one battery (D) recommences production and the other battery (G) enters regeneration. The invention is applicable to the demineralisation of water and to any treatment of an aqueous or nonaqueous solution using ion exchangers.
