Abstract: A printer operatively associated with an electronic weigher includes an input unit having numeric keys or format keys, a memory device storing a plurality of programs for controlling positions at which data are to be printed on a label as well as the size of the printed data, each program corresponding to a different label format, reading means for reading out of the memory device a program corresponding to a format designated by operating the keys of the input unit, and a printing mechanism for printing predetermined data on a label at a predetermined position of the label on the basis of the program read out of the memory device.

Abstract: A drum rotatable about an axis through its center of gravity carries troughs located in a circle concentric to said axis and which are charged at a certain level with flowing material to be measured as to quantity, whereby the drum is influenced by a driving moment from the weight of the charged material. After a certain rotation of the drum, the troughs discharge the charged material at a lower level than said charging level. Means are provided for counteracting rotation of the drum by said driving moment, said means including interconnected scoops arranged in a circle concentric to an axis through the common center of gravity of the scoops, said last axis forming an angle with a vertical line. The drum rotates the scoops around said last-mentioned axis, and the scoops successively elevate a second material from a certain level and discharge it at a higher level.
