摘要： A fuel tank arrangement for a motor vehicle. The arrangement includes a fuel tank containing fuel therein and having a gas space disposed above the fuel, and a venting device connected to the fuel tank. The venting device includes an activated charcoal filter and a venting conduit connecting the gas space to the activated charcoal filter for establishing gas communication therebetween. A stop valve is disposed in the venting conduit and is adapted to open gas communication between the gas space and the activated charcoal filter during refueling. Moreover, a fuel separator is disposed in the venting conduit for separating fuel from a gas flow through the venting conduit thereby yielding separated fuel.

摘要： A portable work apparatus has a combustion engine for driving a work tool. An air/fuel mixture is supplied to the engine via a carburetor which is provided with an electrical heating element for heating to a given temperature. The heating element is connected to a switch via which electrical energy, which is provided by a generator driven by the engine, is supplied. When a given temperature is exceeded, the switch interrupts the energy supply. To achieve an exact temperature control, the ohmic resistance value of the heating element is stored in a memory in dependence on the temperature. The current flowing through the heating element and the voltage drop at the heating element are measured and the instantaneous resistance of the heating element is calculated therefrom. This calculated value is compared to the value stored in the memory to open or close the switch in dependence on the comparison.

摘要： A hand-held work tool has a housing with a carburetor heater and a grip heater. An internal combustion engine is mounted in the housing and has a crankshaft and an ignition system. The ignition system has a pole wheel with permanent magnets fastened sequentially at a periphery of the pole wheel in the circumferential direction. Charge armatures are mounted in the housing and close the magnetic circuit between neighboring permanent magnets. The charge armatures have legs and excitation coils mounted on the legs. Upon rotation of the pole wheel, the permanent magnets generate an electric current in the excitation coils, wherein a first set of excitation coils is combined to a first partial generator and connected to an electric circuit of the carburetor heater and a second set of the excitation coils is combined to a second partial generator and connected to an electric circuit of the grip heater such that the electric current is supplied respectively to the carburetor heater and the grip heater. The excitation coils of the first set are arranged in a row adjacent to one another in the circumferential direction. The excitation coils of the second set are arranged in a row adjacent to one another in the circumferential direction.

摘要： A desk with a channel which extends directly below the table top on the backside thereof and which is removably guided in the desk. The channel has a U or L-shaped profile for receiving cables and wires therein. The outer leg of the profile is in alignment, in the retracted condition thereof, with the desk wall and has openings for facilitating an exiting of the cables and wires therethrough. At least on one side of the channel which extends parallel to the table top there is secured a further channel extending perpendicularly to the channel and which extends downwardly. This further channel together with the first channel is movable and can be moved into a recess in a base of the desk and has a connection to the horizontally extending channel.
