20100186526 | Method for mounting a capacitive level sensor in a liquid tank - Method for mounting a capacitive level sensor inside a liquid tank having a bottom wall, the sensor having a foot and a measuring portion comprising at least one capacitive element supported by a rigid support extending from said foot, wherein the foot is fixedly secured to the bottom wall of the tank through a retainer, and according to which the rigid support forms an angle with the foot so that the length of the measuring portion of the sensor is higher than the height of the tank in the portion where the foot is located. | 07-29-2010 |
20110094658 | Method for manufacturing a storage tank - Method for manufacturing a storage tank comprising an inner liner, an outer filament winding and a connecting part. The method comprises the steps of: blow molding the inner liner by extruding a parison, pinching the inner liner at least at one extremity to create a pinch and then blowing the parison; providing the connecting part with a slot of appropriate shape and size to receive a part of the pinch; inserting the part of the pinch in the slot so as to secure the inner liner and the connecting part; and applying the outer filament winding around the liner and the connecting part. | 04-28-2011 |
20120097318 | Process For Reinforcing A Rigid Plastic Fuel Tank - Process for reinforcing a plastic fuel tank comprising a wall defining an internal closed volume, according to which a structural member is fixed to the wall of the tank outside the closed volume, in at least two points being located in two different portions of said wall where a deflection induced when the tank is filled with fuel, is low; and said structure having at least one contact point with the tank wall in a portion of said wall where the deflection is high. | 04-26-2012 |
20140027958 | PROCESS FOR MANUFACTURING A FUEL TANK - A process for manufacturing a plastic fuel tank including at least one component, by molding a parison using a mold including two impressions and a core, the process including: introducing a parison into the mold impressions; introducing a core inside the parison, the core having a moving device including the at least one component closing the mold so that the impressions come into leaktight contact with the core; pressing the parison against the impressions by blowing through the core and/or applying a vacuum behind the impressions; fastening the at least one component on an inner wall of the parison; opening the mold to withdraw the core; and final molding the parison by blow-molding and/or thermoforming; and to enable its fastening to the parison, the component is moved away from the core by the moving device through a combination of a rotational motion and a linear motion. | 01-30-2014 |
20150354429 | METHOD FOR MONITORING UREA QUALITY OF AN SCR SYSTEM - A method for monitoring urea concentration and quality in a urea solution stored in a tank of an SCR system. The system comprising a pump driven by a motor and the pressure of which is controlled by a controller. The method comprises the steps of:—measuring a parameter value characteristic of the energy transmitted by the motor to the pump;—determining a urea concentration value based upon the parameter value characteristic of the energy transmitted by the motor to the pump. | 12-10-2015 |
20160123929 | VEHICLE UREA TANK ASSOCIATED WITH A SENSING CHAMBER FOR ACOUSTIC QUALITY AND LEVEL SENSING - A device to measure a quality of a urea solution of a vehicle urea tank or of a urea solution coming from a tank, includes a chamber, at least one ultrasonic transceiver configured to vertically emit an ultrasonic wave in the chamber, and a deflector extending in the chamber above the transceiver. The chamber includes an inlet for filling the chamber with a urea solution so that a level of the urea solution in the chamber reaches at least the deflector. | 05-05-2016 |
