Patent FR-2660996-A1 (FR)
Inventor: HERVE LEFEVRE
IPC: G01C19/72
Filed: 1990-04-17
Abstract: A fiber optic measuring device can be used, for example, as a rate gyro. Variation in a measured parameters engenders a phase difference between two waves. The measuring device includes a light source 1, a SAGNAC ring interferometer 2, a detector 3, a phase modulator 4, and a electronic unit 7. The electronic unit 7 includes a processing system 9 which furnishes a signal that is a function of the measured parameter and an electronic sub-unit 12 for controlling the phase modulator 4. The control signal for the modulator is a superposition of a first, periodic gating, bias signal  PHI b(t) with period 2 tau and amplitude  PHI bm, and of a second, staircase, negative-feedback signal  PHI m(t) synchronized with  PHI b(t), each step of which has a duration equal to  tau  or to one of its sub-multiples, and an amplitude  PHI s, which is a function of the value of the measured parameter and which falls back to zero when its amplitude exceeds a predetermined value  PHI mm .  PHI bm and  PHI mm are slaved to 2 PHI bm+ PHI mm=2n pi  (where n is an integer). The response to the singular phase shift introduced during the fall-back of the negative-feedback signal is for this slaving and hence is used to keep the gain of the modulation chain constant.

Title: Cleaning machine for automatic cleaning of inspectable sewers
Inventor: JEAN-LUC LORINI
IPC: E03F9/00
Filed: 1991-01-07
Abstract: Variable-geometry cleaning machine for cleaning ovoid sewers whatever their dimensions. The invention relates to a carriage whose purpose is to reduce somewhat the volume of an ovoid sewer in order to channel the pressure and flow of water of a combined water-type cleaning apparatus ["hydrocureur"]. This vehicle, which is usually used for cleaning tubular sewers (15 cm to 100 cm), could be used to clean an ovoid sewer (90 cm to 200 cm in height). The chassis consists of a frame (1) on which the cleaning head (3) with its nozzles (24) is mounted. The pipe of the truck is screwed to this head. The rear wheels (2) of the machine which run along the invert of the sewer are mounted on this frame (1). At the front are the wheels (6) which run on the base of the walls of the sewer. These wheels (6) are mounted on two arms (4), (5) whose length and separation are adjustable. The front and rear of the machine are connected by a central beam (9) which gives the machine its rigidity. This beam is attached to the wheeled parts by means of two height-adjustable brackets (8). Bolted to this beam (9) is the main metal sheet (10) and on each side of this sheet (10) a wing (11) is attached by a joint (12), (13). To prevent the machine from rising as it approaches an access hole (shaft) from which it will be removed, it has a length-adjustable retaining bar (17) with a wheel (18) at its end which rolls along the top of the sewer. To allow the machine to be moved manually, there are two detachable handles on brackets (19) at the rear.
