Abstract: A method for weighing masses on a conveyor system (18) on which the masses to be weighed are advanced in horizontal direction and which includes a conveyor section (24) that is limp in a vertical bending direction, including the steps of continuously measuring the weight force that acts upon the limp conveyor section (24) while the masses are advanced on this conveyor section, recording a force/displacement function that indicates the weight force as a function of the distance traveled by the conveyor system (18), and calculating the mass flow rate of the conveyor system by evaluating the force/displacement function.

Abstract: A machine for processing food products, includes a processing tool oscillatingly driven by a motor and a drive train, and a trigger system which, in each cycle of oscillating movement of the processing tool, triggers a predetermined action of the machine at a predetermined timing, the trigger system including a signal generator arranged in the drive train to deliver a reference time signal in each cycle, a timer measuring a time passed since the last occurrence of the reference time signal, and an electronic control device storing a displacement/time curve of the processing tool for at least one processing speed of the machine and in which a position of the processing tool is programmable at which the action shall be triggered, the control device determining on the basis of the displacement/time curve, the trigger timing corresponding to that position and triggering the action when the timer reaches this timing.

Abstract: Filter installation for liquids, including a basin with at least one closable suction opening, and a filter, which has a filter element and, from a removal position above the liquid can be lowered in a straight line to an operating position assigned to the suction opening. The suction opening, in an operating position of the filter, communicates with an inner space of the filter and, is connected essentially only through the filter element with liquid outside of the filter. There is a sealing device, which, during the lowering of the filter, while an external side of the filter is in contact with the liquid in the basin, seals the inner space of the filter from the liquid in the basin, so that the inner space of the filter is connected essentially only through the filter element with the liquid outside of the filter.
