Patent FR-2723278-A1 (FR)
Title: Radio transmission method for communication with aircraft
Inventor: GIRAUDO MICHEL
IPC: H03D3/24
Filed: 1984-12-04
Abstract: The method includes transmission of a carrier (30-88 MHz) which is frequency modulated and is demodulated using a PLL (201). If noise is presence of noise which jams the transmission, the frequency modulation is abandoned, and the carrier is modulated on an "all-or-nothing" OOK format using short bursts of transmission. The signal is demodulated by testing (301) the locked state of the PLL using a Viterbi circuit. The carrier is in the frequency band 30-88 MHz, while the rate of modulation using the "all-or-nothing" technique is preferably at a rate of 25 bits per second.

Title: Detector of an anomaly in the flow time of a fluid or of a gas
IPC: G01M3/28
Filed: 1985-11-29
Abstract: Device making it possible, without the requirement of an external energy source, to detect a leak of liquid or of gas which is characterised by an abnormally long time for its flow in a pipe. A pressure reducer 2, 3, 4 creates, during the flow, a pressure difference between the chambers 1, 10 and the chambers 6, 16 which is used in order to fill, via the calibrated orifice in the partition 12, the chamber 14 which is variable in volume by deformation of the wall 13 or in the case of use with the gas, by displacement in a liquid 27 of the mobile wall 15. Conversely, the volume of the chamber 14 decreases in the absence of flow by the action of the spring 17 or of the weight of the mobile wall 15. At the end of travel, the flap 21 closes the seat 23, with the force created by the pressure drop at 8, possibly by the spring 20 freed by the wall 15 deactivating the part 18. The screw 26 allows manual reactivation.

Title: Drive wheel with kinematic energy for a human-propulsion vehicle
IPC: B62M1/10
Filed: 1985-12-30
Abstract: The present invention relates to a device making it possible, on a human-propulsion cycle, to use the kinetic energy developed by an inertia flywheel 6 rotating at high speed inside the rear drive wheel itself and actuated by the operator with the aid of a crank mechanism and gears 6. The transmission of the kinetic energy of the flywheel to the drive wheel 3 is modulated by the operator as a function of the speed of the vehicle by virtue of a kinetic chain consisting of a gear box and a friction clutch 8 which securely fasten the flywheel to the wheel. The rotational speed of the inertia flywheel is, in normal use, greater than that of the drive wheel. It is possible to disengage the flywheel in order to allow the use of the vehicle for its conventional purpose.

Title: Removable, pivoting and sliding flag support device for conical or similar poles
IPC: G09F17/00
Filed: 1986-03-20
Abstract: The invention relates to a removable, pivoting and sliding flag support device for poles of conical tube shape or similar poles, with an internal halyard and a rotating pommel or similar devices, equally applicable to cylindrical poles. The flag 17 is hooked onto a movable stem 11, drawn along the pole 1 by sliding vertically 8, which stem 11 in its upper end position then leaves its vertical guide 8 and simultaneously is rendered integral with the rotating pommel 2 which holds it by tension on the halyard 4. This stem 11 carrying the flag 17 is held parallel to the axis of the pole 1 by insertion of its upper end 12 into the underside 6 of the pommel 2, and by insertion of its other end 23 into a circular horizontal rail 10 incorporated into the pole 1, on the inside of which it circulates freely. This stem 11 which is manoeuvrable from the bottom of the pole 1 also follows, in its upper position, all the multiple circular fluctuations of the flag 17 and prevents it being wound around the pole 1 under the effect of air turbulence.

Title: Rotational vibration damper
Inventor: ANDRA RAINER
IPC: F16F15/12
Filed: 1987-04-13
Abstract: A rotational vibration damper in which the hub ring 4 and the flywheel ring 3 are connected by elastic units made from vulcanised rubber and distributed over the periphery. These units comprise first and second elastic elements 1, 2 in the form of columns, which are each extended via their outer face and which are located at a certain distance via their inner face. The second elastic elements are prestressed by the first elastic element, and, when the rotational vibration damper is not rotating, their outer faces are distant from the inner face of the flywheel ring 3. They are pressed, without being able to move, onto the inner face of the flywheel ring by the centrifugal force resulting from a desired rotational speed, which gives rise to their elastic action becoming in parallel with the elastic action of the base elastic elements 6.
