Abstract: The invention relates to a bar system (1) for simultaneously pouring beer (3) from a reservoir (2) into a plurality of containers such as glasses (4), comprising a supply line (5) having an adjoining distributor region (6) having a plurality of outlets (7), wherein the beer (3) can be conducted via the supply line (5) into the distributor region (6) and via the latter into the containers such as glasses (4). In order to fill the containers such as glasses (4) uniformly with beer (3) and with a head of foam of equal height, it is possible according to the invention to till the distributor region (6) completely with beer (3) when the supply line (5) is partially full.

Abstract: The invention relates to a method for testing for the presence of nickel sulfide inclusions in an object made of glass. In order to be able to perform this in an energy-saving and rapid manner, according to the invention a method is proposed for testing for the presence of nickel sulfide inclusions in an object made of glass, such as a tempered safety glass, during a tempering or hardening thereof, the object being brought to a temperature of at least 500° C. and at this temperature an electromagnetic radiation emitted from the object being recorded and evaluated, after which the object is intensely cooled in order to temper or harden it. The invention further comprises a device for testing for the presence of nickel sulfide inclusions in an object made of glass, such as a tempered safety glass.
