Patent FR-2699031-A1 (FR)
Title: Automatic duplex or half-duplex momomode or multimode communication between two telephone units
Inventor: OLIVIER NORMAND
IPC: H04L5/14
Filed: 1992-11-25
Abstract: The communication method between two switched telephone units involves exchanging matching signal streams. A fast equipment sends out the matching signal in half duplex. The second equipment, on recognition and validation of the validation segment, emits a second signal in the recognised mode. The first equipment analyses the second signal, and if it recognises the signal it stays in the accepted mode for reception and sets up the communication. If the second transmission mode is slower, the second equipment does not recognise the first mode. In this situation, the roles of the equipment are reversed, and the validation procedure occurs w.r.t. the previous sequence but in the second mode of transmission.

Title: Differential hydraulic circuit for feed and locking up of controlled double acting jack
Inventor: MATHOULIN PIERRE
IPC: B62D1/26
Filed: 1995-05-24
Abstract: The differential hydraulic system is made up of a hydraulic power source (1) supplying a fluid. A distribution valve (2) feeds the jack (3) via the supply feed (4) and the return feed (5). A compact feed differential unit (9) is interposed between the feeds. This unit is actuated, in view of the extension of the rod (3a) of the jack.
