Patent FR-2290334-A1 (FR)
Inventor: BELART JUAN
IPC: B60T11/20
Filed: 1975-11-06
Abstract: The brake system includes a tandem master cylinder and a control valve for introducing pressure supplied from a power source. The main feature of the present invention is that the pressure from the power source is first introduced into annular chambers behind the sleeve seals of both the tandem master-cylinder pistons. This makes it possible for the pistons to travel only a small distance if power from the power source is available. Thus, the pistons can be dimensioned in accordance with the force the driver is able to exert with his foot in the event of failure of the power source.

Patent FR-2348429-A1 (FR)
IPC: F16L9/21
Filed: 1977-04-18
Abstract: The acoustic input conductances of the mutually opposite sound-absorbing margins are different from one another. This difference in the acoustic input conductances of mutually opposite duct sides is constant or at least constant in sections in the sound propagation direction. To this end, either partitions (4), which are arranged outside the splitter centre, are arranged inside the splitters (1), or different coverings of the mutually opposite splitter coverings are formed, or materials with different flow resistances or adjacently lying alternate arrangements of splitters are formed. With this, during the sound propagation, energy is constantly drawn off from the symmetrical wave form which can only be weakly damped and is changed into the antisymmetrical wave form which is provided with greater propagation damping because in this manner an increased damping of the entire sound field results overall.
