Abstract: An apparatus for ascertaining the alcohol content or the calorific value of a mixture containing alcohol and gasoline includes an electrically conductive housing through which the mixture flows and in which at least one physical parameter of the mixture is measured to produce a measurement. An electronic measuring circuit is disposed in the housing for evaluating the measurement. The housing has a wall with a part of the wall forming a first electrode of a capacitor. An intermediate plate is associated with the housing. An electrically conductive sensor element is secured in the intermediate plate and partly surrounded by the mixture. The electrically conductive sensor element forms a second electrode of the capacitor and forms an electrical connection between the second electrode and the measuring circuit.

Abstract: In a plate belt conveyor for steep conveying in the overlapping region of adjacent plates (5, 6), a pocket (15) is provided which is formed by a seam (12) and an upward projecting leg (8) of the lower rear plate end as well as a roof-like arch (9) projecting over the seam (12) and the leg (8) with downward directed leg (10) of the front upper plate end. The rising flank of the seam (12) is concentrically formed with respect to the chain fulcrum (14) in such a manner that when the leading plate (6) is angled relative to the trailing plate (5), the pocket (15) firstly remains closed and opens only on a further angling of the plate.
