Patent FR-2750897-A1 (FR)
Inventor: RODRIGUES JOSE
IPC: B05B12/08
Filed: 1996-07-10
Abstract: Air (3), carrying powder particles picked up by venturi action from an air-agitated reservoir, is diluted and/or accelerated on entry (21) by air injected via a central nozzle (25a), directed downstream. The stream then enters the annular passage (12) between concentric inner (14) and outer (13) tubes of insulating material. The former, plugged by conical entry (14b) and exit (14c) fairings, is supported by perforated spacer rings (19, 20). The tribo-electric charge, proportional to the injected control air-flow (25) is measured by the current collected by a conducting carbon-fibre tube (26) close-fitting over the outer insulated tube (13) and passed to earth (27, 28) via an external control unit, automatically adjusting the injected air-flow. The charged air-stream is finally projected through the end nozzle (18).

Title: Determination of remaining ink quantity in an ink jet reservoir
Inventor: FROGER MARIE HELENE
IPC: B41J2/175
Filed: 1997-03-28
Abstract: Procedure and device for determination of the quantity of a consumable product remaining within a reservoir especially ink within the reservoir of an inkjet printer. The reservoir (140) forms part of a moving assembly, which can be displaced along a predetermined trajectory. The reservoir (140) is placed within the dielectric space of a capacitor the two plates (148,146), which extend lengthways along the reservoir trajectory. A signal generator (207) applies a signal to the capacitor and the reservoir is displaced until a comparator (205) changes state when a threshold is reached. The distance travelled by the reservoir is proportional to the amount of ink within it. The threshold value is a capacitance value to which the capacitor is reduced by movement of the reservoir. The distance moved is dependent on the dielectric (ink) quantity within the capacitor.
