Abstract: Disclosed is a water based method for extracting caffeine from alkaloid containing substances, in particular tea leaves. The method can be performed without the use of artificial substances. The method allows the other soluble, non-caffeine components of alkaloid containing substances to be part of the decaffeinated product, in particular, components such as catechins and antioxidants. Advantageously, the caffeine extracted from the alkaloid containing substances is reversibly adsorbed to an adsorbent and high percentile of the caffeine can be recovered from the adsorbent.

Abstract: A liquid-cooled cooling screen for an entrained-flow gasifier for gasification of fuels in dust or liquid form using a gasifier agent containing free oxygen, at pressures between atmospheric pressure and 8 MPa and gasification temperatures between 1200 and 1900° C. The liquid-cooled cooling screen of which the cooling pipes in the central cylindrical section have thinner walls than the cooling pipes in the lower and upper conical sections. A cooling screen design has sufficient strength under high pressure difference over the cooling screen wall, a pipe wall thickness which ensures reliable operation of the cooling screen and high heat throughput, and pressure equalization between the cooling screen gap and the reaction chamber under all operating circumstances.

Abstract: In the active transportation mode of a motor vehicle, only the forward gears can be selected. The weakest shift element, in particular the weakest brake or clutch in an automatic transmission, always is closed in the forward gears. Preferably, manual shifting options in an electronically controlled automatic transmission with a manual mode are additionally suppressed.

Abstract: A pressure filtration system for cleaning residual quenching water of a gasifying device that gasifies carbon-containing fuels under elevated pressure is provided. The soot water from the quencher is passed to a filter system, which has pressure filter chambers operating alternately in filtering mode under gasifying pressure or in cleaning mode. The filtrate from these chambers is passed to a quenching water reservoir, from which the quencher is fed with quenching water. Only small temperature and pressure losses with respect to the residual quenching water leaving, and only a small additional amount of energy has to be expended to overcome the remaining pressure difference to bring the filtrate that is to be returned back to the gasifying pressure. The residual quenching water is cleaned substantially under gasifying pressure in a pressure filter, avoids flash evaporation of the residual quenching water into the vacuum area, with vapour cooling and a subsequent increase in pressure and reheating.

Abstract: The apparatus suppresses manual shifting options in an electronically controlled automatic transmission with a manual mode in the active transportation mode of a motor vehicle by appropriate programming of an electronic transmission control unit. The transmission can be operated only in the automatic mode. Preferably, only the forward gears can be selected in this case, the weakest shift element, in particular the weakest brake or clutch in an automatic transmission, always being closed in the forward gears.

Abstract: A method and electronic control unit are provided for controlling an automatic transmission by way of the electronic control unit in a motor vehicle during a skidding turn, during which the motor vehicle first travels straight with a velocity above a predefined threshold value or within a predefined range with the reverse gearspeed engaged and, subsequently, experiences a defined steering jolt, by means of which a rotational movement is initiated. When a defined rotational angle is exceeded, the automatic transmission is automatically shifted from the reverse gearspeed into a neutral position.

Abstract: Separation of dust in a quenching device arranged downstream of an entrained-flow gasification system is increased by a baffle with a double deflection system for deflecting the crude gas at approximately 180° angle. An additional spraying element is provided. The arrangement can be single-sided or double-sided, or can include an additional weir.

Abstract: A three-stage quenching and scrubbing system for treatment of hot crude gases and liquid slag after an entrained flow gasification. In the first primary stage, cooling and scrubbing water is injected such that slag can no longer adhere to the wall of the central tube and the conversion reaction of the carbon monoxide with water vapor to give hydrogen can proceed to close to the equilibrium. A secondary quenching and scrubbing stage takes the form of a bubble column, and further cooling and the deposition of coarse dust and slag are effected in a water bath. The rest of the treatment is through intensive spraying in a tertiary quenching and scrubbing the gas stage, nozzle rings for deposition of fine slag and partly of fine dust. All three quenching and scrubbing stages enable cooling of the crude gas down to the water vapor dew point determined by the plant pressure.

Abstract: A device for treating steam-saturated crude gases from the entrained flow gasification of fuels before entry into heat exchanges sited upstream of a crude gas converting operation. To avoid solid deposits in an entrance region of the heat exchangers, a crude gas is converted from a saturated into the superheated state by supply of hot gas. Hot gas contemplated is superheated high pressure steam or recycled superheated converted crude gas.

Abstract: A device for the reliable measurement and control of the filling level in the quencher sump of a quenching chamber arranged downstream of the gasifying chamber is provided. The device has a differential-pressure transmitter. The measuring location recording the pressure of the gas chamber is flushed with inert gas. The device unproblematically senses the pressures in the quenching chamber and at the bottom of the quencher sump. The difference between which is used as a controlled variable for the filling level.
