Abstract: A separating conveyor for transferring unit loads, in particular air luggage, from a conveyor belt (3) to at least one adjacent branching conveyor, has traveling undercarriages (7) arranged one after the other in the transport direction (F), movable along a guiding rail (6) and interconnected by driven traction means (4) to form an endless revolving chain, and tilting arms (8) arranged on the undercarriages (7), a coupling rod (12) being joined to each tilting arm (8) outside of its axis (9) to ensure the tilting movement of the tiling arms (8). In order to ensure the rotation of the tilting arms (8) about the axis (9) over a switchable switching element (17), the guiding roller (14) can be deflected into a tilting rail (16) vertically offset in relation to the guiding rail (15).

Abstract: The invention relates to a calcinated catalyst for converting paraffinic hydrocarbon into corresponding olefin through dehydrogenation. The catalyst is an oxidic, heat-stable carrier material and contains a catalytic active constituent, which is applied on the carrier material and has the following composition (in wt. % in relation to the entire weight of the catalyst): a) 0.2 to 2.0% of at least one element of the groups Pt and Ir and, acting as a promoter, a combination of elements from the six following groups of substances: b) 0.2 to 5.0% of at least one of the following elements Ge, Sn, Pb, Ga, In, Tl; c) 0.1 to 5.0% of at least one of the following elements Li, Na, K, Rb, Cs, Fr; d) 0.2 to 5.0% of at least one of the following elements Fe, Co, Ni, Pd; e) 1.0 to 5.0% P; f) 0.2 to 5.0% of at least one of the following elements Be, Mg, Ca, Sr, Ba, Ra and lanthanides and g) 0.1 to 2.0% Cl.

Abstract: A fuel cell system which has a fuel cell with a supply line and a discharge line for a fuel as well as a supply line and a discharge line for an oxidizing agent. Also provided is a fuel tank which contains, for example, benzene or methanol for producing the fuel for the fuel cell. To avoid the release of hydrocarbons from the fuel contained in the tank, a filter element, for example an active carbon filter, is connected to the fuel tank. To be able to regenerate the filter element, the filter element is connected to the discharge line for the oxidizing agent and/or the discharge line for the fuel. The filter element is regenerated by the flow of exhaust gas from the fuel cell. The filter element is preferably connected via a connecting line to a burner, with the result that the hydrocarbons taken up by the flow of exhaust gas can be burned in the burner. Furthermore, by designing the fuel cell system appropriately, a leakage diagnosis can also be performed in the fuel tank.
