  • Publication number: 20080251523
    Abstract: A ventilation device (1) for a fuel container (2) with a liquid trap (3) and a suction jet pump (8) which is provided for emptying the liquid trap (3) has a filling-level limit switch (11) for detecting the filling level of fuel in the liquid trap (3). A valve (10) which is connected to the filling-level limit switch (11) is connected upstream of the suction jet pump (8). The suction jet pump (8) is first activated by means of the valve (10) when the intended filling level of fuel in the liquid trap (3) is exceeded.

  • Patent number: 7435556
    Abstract: This invention pertains to a method for increasing the ratio of the pHBA ester glucoside to total pHBA glucose conjugates in pHBA-producing microorganisms and green plant cells using nucleic acid fragments encoding plant glucosyltransferases that exhibit catalytic activity with p-hydroxybenzoic acid (pHBA) as a substrate and only attach glucose to the aromatic carboxyl group of pHBA, to form the pHBA glucose ester.

  • Publication number: 20080236551
    Abstract: In a control method for an internal combustion engine (1) which has a fuel tank (18), a fuel vapor storage device (25) for storing the escaping fuel vapors and a controllable valve (28) for adjusting the stream of fuel vapors fed to the intake tract (4) during a period of tank ventilation, the valve (28) is controlled in such a way according to the method that the stream of fuel vapors varies during the tank ventilation period. The regeneration of the fuel vapor storage device is intended to be improved thereby.

  • Publication number: 20080223865
    Abstract: A device for delivering fuel has a fuel delivery unit placed inside a fuel tank and which consists of a swirl pot with a fuel pump situated therein for delivering fuel out via a flow line to an internal combustion engine, and with a ventilation system located inside the fuel tank and serves to withdraw fuel vapors from the fuel tank. This ventilation system consists of ventilation lines and a liquid trap for precipitating fuel. The ventilation lines are arranged with one end in the upper area of the fuel tank, and, with the other end, lead into the liquid trap. An activated charcoal filter located downstream from the liquid trap has a connection to the atmosphere. The liquid trap and the activated charcoal filter are situated next and at the height of the swirl pot. At least the liquid trap is mechanically connected to the swirl pot.

  • Patent number: 7361811
    Abstract: The invention relates to high-level production of pHBA in green plants using a unique expression cassette. The latter comprises a chorismate pyruvate lyase (CPL) coding sequence operably linked to a suitable promoter capable of driving protein expression in higher plants. Additionally, the CPL cassette comprises a sequence encoding a chloroplast transit peptide, its natural cleavage site, and a small portion of the transit peptide donor protein fused to the N-terminus of CPL. The chloroplast targeting sequence targets the foreign protein to the chloroplast compartment and aids in its uptake into the organelle. The cleavage site is unique to the transit peptide, and cleavage of the chimeric protein encoded by the cassette at this site releases a novel polypeptide that has full enzyme activity, comprising the mature CPL enzyme and a small portion of the transit peptide donor.

  • Publication number: 20070184092
    Abstract: Compositions comprising a modulated tocol content in a plant or plant part are provided. In specific embodiments, the compositions and methods of the invention modulate tocol content by modulating the level of a polypeptide having a LEC1-type B domain in combination with modulating the level of at least one other polypeptide involved in tocol biosynthesis. Plants, plant parts, grain, seed and oil having the modulated tocol level are also provided. Methods to enhance oxidative stress tolerance of a plant or plant part, increase shelf-life, enhance the nutritional value, and improve tissue quality are also provided.
