Abstract: An apparatus comprises at least one cooking device (21-24), in particular a baking oven (22) or a steam-cooking appliance (21), for preparing at least one foodstuff. The apparatus further comprises an input device (3), an output device (4), and a central control unit (1). The central control unit (1) identifies a recipe based upon input parameters specifying the foodstuffs as well as further ingredients and generates a cooking process for the recipe. The recipe is output by means of the output device (4) and the cooking process is transmitted to a cooking process control (26) of the cooking device (21-24).

Abstract: A hydraulic valve control circuit of a hydraulic valve comprises an external voltage supply, an output stage having a voltage supply input and at least one output configured to actuate an actuator of the hydraulic valve, an overcurrent protective device disposed in a path between the external voltage supply and the voltage supply input, an enable input configured to activate and deactivate the output stage, and a switch configured to connect the at least one output to a fixed potential when the output stage is deactivated.

Abstract: The invention relates to a float (5) for a fill level sensor, comprised of a fuel-resistant plastic (7), an expanding means (8) and/or filler (9), whereby the expanding means consists of gas-filled plastic balls (11) that are provided in the form of microspheres (8), and the filler consists of micro-hollow balls (9). The microspheres (8) and the micro-hollow balls (9) are surrounded by fuel-resistant plastic (7).

Abstract: A plastic fuel tank is formed by welding together an upper plastic shell (1) having an upper closing wall (8) and a lower plastic shell (2) forming a bottom (7). The two plastic shells (1, 2) are produced by the injection molding method. In order to adhere to an exact distance between the upper closing wall (8) and the bottom (7), spacers (9) coming into abutment during the welding operation are provided in the fuel tank.

Abstract: A fuel line (1) for a suction jet pump has a nozzle (2) which is produced integrally with a bend piece (3). This avoids shoulders, which may cause turbulence in a flow, within the fuel line (1). The suction jet pump equipped with this fuel line (1) is consequently particularly highly efficient.

Abstract: A device for measuring a fill level of liquid in a container includes a measuring tube arranged inside the container and an ultrasonic sensor arranged outside the container such that a portion of the wall of the container is arranged between the measuring tube and the ultrasonic sensor. The ultrasonic sensor therefore has no contact with the liquid located in the container.

Abstract: In a fuel tank (1) with a plug which is to be opened, in particular, during maintenance work, a plugging part (6) is fastened in a trough-like depression (2) of the wall of the fuel tank (1) by means of a nut (7). The nut (7) has a thread (9) intended for tapping into a bead (5) of the fuel tank (1). As a result, the fuel tank (1) can be manufactured particularly cost-effectively from geometrically simple parts.

Abstract: A fuel tank for a motor vehicle comprising a wall composed of two shells arranged one above the other. The outer shell of the wall preferably has an inlet orifice and an outlet orifice. A filter element is arranged in front of the outlet orifice. Scavenging air from the inlet orifice thereby passes first into a gap between the shells and subsequently to a filter element. As a result, fuel vapors can no longer diffuse through the wall and pollute the environment.

Abstract: In an extraction method for a casting mold with a plurality of mold parts which can be displaced by electric motors, the electric motors are activated as a function of values deposited in a memory. The values represent required values for the respective positions of the mold parts. By this means, molded parts with complicated shapes can be extracted, with particularly small structural requirements, from the casting mold.

Abstract: A device for measuring a fill level of a liquid includes an ultrasonic sensor with two sensor elements. One of the sensor elements determines the echo time of an ultrasonic wave to a float which follows the liquid level. The other of the sensor elements determines the echo time of the ultrasonic wave up to a measuring reflector arranged at a known distance from the other of the sensor elements. An evaluation unit compares the echo times and determines the fill level of the liquid from the ratio of echo times and from the known distance to the measuring reflector.

Abstract: A delivery device (2) for delivering fuel, having a delivery pump (3) and a fuel filter (7), has a bypass line (9) which is conducted past the fuel filter (7). When new, the delivery pump (3) delivers fuel through the fuel filter (7). After the fuel filter (7) has become clogged with dirt, the fuel is delivered by the bypass line (9) through a second fuel filter (10). By this means, pollution of the environment with fuel is kept particularly low.

Abstract: Arranged in a fuel tank of a motor vehicle are guide elements and guide plates which deflect a flow of the fuel toward a wall of the fuel tank at a flat angle. Splashing noises of the fuel are thereby markedly reduced. The guide plates form a channel with a calming region, in which the flow of the fuel is throttled.

Abstract: A fuel tank for a motor vehicle, having a wall (3) which is manufactured from plastic, in particular by injection molding, is provided on its inside with a permeation barrier (4). The permeation barrier (4) is manufactured from a material which is virtually impenetrable for fuel vapors. The permeation barrier (4) is composed of shell parts (5, 6) which are welded to one another.

Abstract: In a method of producing a fuel tank from plastic, a heating element is located between two shell parts to be welded to one another. When the shell parts are pressed together, the heating element melts into the plastic and produces a weld that provides a fuel-resistant seal. The fuel tank subsequently has a particularly exact shape.

Abstract: A plastic tank comprises a line which is connected at least in certain sections to its wall and is formed in one piece with the plastic tank. For its production, the plastic tank is injection-moulded between a hollow mould and an inner mould inserted into the latter, the mould having a recess, in which a sprue body is formed as the starting material for the line. Before this sprue body can solidify completely, material is blown out from it by means of the internal gas pressure or pressure blowing technique via channels provided in the mould, so that the required line is created there. The lines may be arranged on the outside and/or inside and parallel and/or at an angle to the tank walls.
