摘要： A switch-mode modulator operating at a two-level voltage and including an alternating output stage (3), an optional output filter (5) and a feedback including a function block (14) with a transfer function (MFB). The modulator furthermore includes a forward block (12) provided with means for calculating the difference between the signal (14a) originating from the function block (14) and a reference signal (REF) as well as with a transfer function (MFW). The output (13) of the forward block (12) is the input of a Schmitt-trigger (9), which generates switch on signals (2) for changing the output stage. The output voltage (VOUT) of the modulator applying either after the optional output filter (5) or the output stage (3) is fed back through the function block (14) so as to generate the signal (14a) fed back. The transfer function of the function block (14) and of the forward block (12) is chosen both in response to the transfer function of the output filter (5) and in response to the desired total open-loop-transfer function of the modulator.

摘要： Based on a non-orderly flow of supplied articles, which may also be sticky articles of food, there is effected in a compulsory manner an isolation of mutually separated small article portions, which are moved through a weighing station (20) and thereafter brought together selectively into larger portions, e..g, with a predetermined weight. In a preferred system according to the invention use is made of an endless row of carrier trays (12) which, in two straight runs, pass along a number of receiver containers (22), into which they are selectively emptied after having passed the weighing station. In front of this station distributor means (14, 18) are provided above a horizontal reversing path of the tray chain for ensuring that the supplied articles are distributed to the trays without overlapping therebetween. Various advantageous embodiments of the single parts of the system to work with a desirably high capacity. According to choice, the system may be used for sorting purposes or for the building up of article portions according to batching or combination weighing principles.
