摘要： Carburetor for supplying intermixed air and atomized fuel to an engine comprises an air passageway, having a throttle for passing a controllable amount of atmospheric air, and injection means configured for injecting pressurized fuel into the air passageway in a generally flat spray pattern disposed substantially normal to the air passageway. A bypass chamber is located adjacent to the air passageway, opening thereto for capturing any unimpeded fuel injected by the injection means, returning it to the fuel tank. A metering vane located in the air passageway is configured for allowing passage of substantially all of the fuel into the bypass chamber when there is no airflow in the air passageway and for intercepting a portion of the fuel when the spray pattern is deflected by airflow in the air passageway, directing it into the air passageway. The metering vane is shaped such that the deflected portion of the fuel remains in a predetermined ratio with the airflow over the full range of engine operation.

摘要： Photographic film developing apparatus comprises a sequence of adjacent, horizontally aligned chambers communicating with each other at their top and bottom portions. Each is adapted to contain a selected film-treating fluid agent. An infeed port communicates with one terminal chamber of the sequence and a dishcarge port with the other.Magnetic carriages mounting releasable film grips are dimensioned to traverse the chambers, trailing the film behind them. The carriages are actuated by a magnetic element mounted for reciprocation adjacent the chambers and associated with a reciprocating drive. Reciprocation of the magnetic element in a vertical plane drives the carriages and the film through one chamber after the other, thereby exposing the film sequentially to the action of the treating agents contained in the respective chambers.
