Abstract: The present invention relates to a method for building a shaped body by layer-wise solidification of photopolymerizable building material by means of stereolithography characterized in that the positioning of a blade with respect to a vat bottom is adjusted in such a manner that the resulting predetermined, uniform layer thickness is higher than the predefined layer thickness to be set by lowering a building platform, but does not exceed the predefined layer thickness by more than 50%.

Abstract: A carburetor has a carburetor housing wherein an intake channel section is arranged. A fuel opening opens into the intake channel section. The carburetor has a fuel pump with a pump membrane delimiting a pump chamber connected to a fuel inlet. A pressure controller has a control membrane separating a control chamber from a compensation chamber. The control chamber is connected to a fuel outlet leading out from the carburetor. The compensation chamber is connected to a compensation connection. The carburetor housing has a carburetor body, a pump cover and an intermediate part arranged therebetween. The fuel inlet, the fuel outlet and the compensation connection are formed on the intermediate part. The fuel inlet, the fuel outlet and the compensation connection are arranged on the side of the carburetor that faces away from the combustion engine.

Abstract: A handheld work apparatus includes a gas-operated combustion engine which has a cylinder with a combustion chamber, the combustion chamber being delimited by a piston. The combustion engine is fed combustion air via an intake channel and liquid gas via a supply line. The liquid gas enters into an opening of the supply line in a gas tank, it being possible for the position of the opening of the supply line in the gas tank to be adjusted. A longitudinal section of the supply line lies within the gas tank and is formed from a flexible hose. A weight is arranged in the region of the opening in such a way that liquid gas is fed via the opening to the supply line of the mixture formation unit in every operating position of the work apparatus.

Abstract: An assembly is for filling a gas tank for a combustion engine from a gas-filled storage bottle via a filling device arranged between the tank and the storage bottle. The tank has at least one fill valve for liquefied gas, a pressure relief valve for gas in the gaseous state, and an extraction valve for liquefied gas. The filling device has a gas connection for the storage bottle and has a fill connection for the fill valve. For filling the tank, the fill valve is connected via the filling device to the storage bottle, such that, when the fill valve is open, liquefied gas flows from the storage bottle via the fill valve into the tank. During the inflow of liquefied gas, the pressure relief valve of the tank is at least intermittently open. A filling level gauge is provided for indicating a predefined filling level in the tank.
