Abstract: An apparatus for encoding a multi-channel signal having at least three channels includes an iteration processor, a channel encoder and an output interface. The iteration processor is configured to calculate inter-channel correlation values between each pair of the at least three channels, for selecting a pair including a highest value or including a value above a threshold, and for processing the selected pair using a multi-channel processing operation to derive first multi-channel parameters for the selected pair and to derive first processed channels. The iteration processor is configured to perform the calculating, the selecting and the processing using at least one of the processed channels to derive second multi-channel parameters and second processed channels. The channel encoder is configured to encode channels resulting from an iteration processing to obtain encoded channels.

Abstract: An apparatus for the loading of flour at a mill having at least one filling nozzle, which communicates by way of at least one substantially stationary storage container, a silo or a hopper, and is so constructed that it can be coupled to several input openings of a vehicle to be loaded. In order to connect the filling nozzles to the various input openings of the vehicle to be loaded in succession (or simultaneously), the weighing assembly, which measures the weight of the vehicle together with its load, is constructed so that it incorporates a transport means, in such a way that by moving the vehicle its input openings can be connected in sequence to the filling nozzle for rapid loading of flour in a simple manner. The flour, in particular in a fluidized state, can be conducted though vertical chutes, increasing the control over the amounts loaded into the vehicle and decreasing the possibility of contamination.

Abstract: At a station (1) in a packaging line for folding a flap (2) of a bag (3) along a shaping line (10) of the flap (2) and for compressing the folded flap (2) by a folding element (5) against a resistance member (4), the folding element (5) is driven by a drive mechanism (16) into two directions (8, 9). The two directions are perpendicular to one another. A holding element (11) is provided which can be moved against the shaping line (10) and has a rectilinear shaping edge (12). The rectilinear shaping edge (12) guarantees a straight, position-exact shaping line (10). The folding element (5) causes the folding and compressing, and can be returned into a start position for the next flap (2).
