Title: Sewage purification device
IPC: C02F3/28
Filed: 1987-02-19
Abstract: A device for purifying sewage before spreading or discharging into a liquid medium, combining in a single enclosure the three components necessary for the three successive treatments. It consists of an enclosure 1 divided by partitions of suitable height into three zones intended: the first, 7, for the separation of fats, the second, 8, for the usual biochemical decomposition in a septic tank, the third, 9, for filtration. Cleaning of the fat separation zone can be performed, like that of the septic tank, through the manhole 5, but at different times. The enclosure, always ballasted, never tends to rise out of its housing in the ground. Water from which fat has been separated is combined (arrow 13) with the foul water in the septic tank where the latter arrives directly through the entries 3, 4. The fatty water does not come into contact with the matter from the foul water. After settling, the water flows (arrow 15) into the filtration zone.

Title: Road slowing-down device with selective action
IPC: E01F9/529
Filed: 1987-05-27
Abstract: Device for encouraging road users to respect the speed limit, with selective action. The invention relates to a device for encouraging road users to respect the speed limit operating according to the principle of a hydrostatic pump actuated by the tyres of the vehicles. If the speed is less than the limit, the liquid contained in the cells 7 is discharged through the lateral valves 4 and the vehicle will not be subjected to a jolt when leaving the device. If the speed exceeds the limit, the valves 4 suddenly close and the liquid advances in front of the tyre in question from cell to cell through the valves 5, to build up in the last cell thus forming a hindering obstacle for the offending user.

Title: Device for detecting the concentricity of an insulating coating with a metal wire
IPC: G01B7/28
Filed: 1987-08-11
Abstract: The invention relates to a device for continuous monitoring of the concentricity of a conducting wire with its insulating coating. The device uses the capacitive phenomenon between the conductor itself and the metal periphery of two rollers which rotate freely. Accidental variation in the thickness of the insulator causes a variation in the capacitive system, which is continuously converted by an electronic circuit into an appropriate monitoring parameter. The centring can be corrected continuously, without stopping the coating operation.

Title: Inserting appts. into a hot pressurised enclosure - comprises using a heavy shutter held closed by its own wt.
IPC: F27D99/00
Filed: 1988-02-26
Abstract: A shutter allows measuring or operating apparatus to be inserted into an enclosure containing hot gas under pressure. A heavy shutter, inside the enclosure, mounted to pivot about an horizontal axis is held closed in a vertical position by its own weight. It may be opened by the apparatus being put in place, or by an independent pusher, operated from outside the enclosure. It closes again under its own weight when the apparatus is removed.
