Title: Method of controlling fuel vapor canister purge flow and vapor management valve therefor
Inventor: BENEKER GERRIT V
IPC: F02M25/08
Filed: 1999-09-10
Abstract: A fuel vapor management valve or VMV having an electrically operated vent valve for controlling atmospheric bleed flow to a vacuum signal pressure chamber. The pressure in the signal pressure chamber controls the differential pressure acting on opposite sides of a diaphragm which moves a valve member for regulating fuel vapor purge flow from a canister to the engine intake manifold. Vacuum is applied to the signal pressure chamber through restrictive passages in a connector which prevent sonic flow choking. In one embodiment two orifices are spaced fluidically in series. In another embodiment fluidically parallel laminar flow passages are provided in an element comprising a porous filter preferably formed of fibrous material or sintered metal. In another embodiment, the laminar flow element is disposed fluidically in series with a flow restricting orifice.

Title: A method of and a device for digital signal transmission
Inventor: QUASSO ROBERTO
IPC: H04L12/54
Filed: 2000-01-26
Abstract: A stream of incoming digital signals (I a) is split (10) into a plurality of derived streams (I b) that are sent over respective transmission links (R). The derived streams transmitted in this way (I c) are then bundled again (20) to form a stream of outgoing digital signals (I d). At the transmission end, symbols are inserted into the derived streams (I b) simultaneously and at constant intervals (T), in order to subdivide the transmitted information into packets of equal duration and aligned in time when being transmitted. At the reception end, the above symbols associated to the transmitted derived streams (I c) are generally time-shifted as a consequence of the transmission over the various transmission links (R). At the reception end (20) the time alignment of the above symbols is recovered so as to recover the time alignment of the various transmitted derived streams (I c), so that the subsequent bundling can take place on the streams correctly time-aligned.
