摘要:
The tendency of metallic pigments, especially of aluminum flake pigments, to react with the aqueous medium of a water-born paint composition with the generation of gaseous material is prevented or reduced by incorporating in the composition an agent containing in the molecule at least one P--OH group, or a salt derivative thereof, which is obtained by reacting a compound containing the grouping --O--PO(OH.sub.2) with one or more epoxide group-containing compounds at least one of which also contains at least one aromatic or alicyclic group.

An apparatus for gathering measuring values obtained when weighing unit loads, the value obtained for each weighing being accumulated in a separate receiver means, which comprises a hollow, downwardly open frame forming an internal space in which a support connected to the frame 1 is provided. The support extends transversely across said space to form a passageway for a load carrier which is movable in said space to the inner wall of the frame, which load carrier encloses said support and is adapted to receive a known pressure-sensitive member for delivering a load measuring value for registration in said receiver means.

A weighbelt is conventionally placed in or associated with a production line for weighing material supplied during production. The weighbelt of the invention has a belt 10 which can be lifted by rollers 18 out of contact with a planar support plate 16 without stopping the belt 10. A known mass 24 is then lowered into a cradle 26 to provide a downward force on the plate 16 to calibrate output signals of a strain gauge 22. The strain gauge 22 provides output signals when the belt is supported by the plate 16 indicative of the material loading on the belt 10. The weighbelt can be calibrated without stopping the belt 10 and disrupting production.

An apparatus for the exact weighing of materials, especially fruit and vegetables, in lots of mixed-size pieces feeds a plurality of pieces to a plurality of scales, carries out the weighing of one or more pieces on single scales, calculates the sum of successive groups of weights read from differently selected scales, and the difference between the wanted draft and each of said sums in order to select the group of weights and hence of scales carrying pieces for a total weight differing from the wanted draft to a predetermined allowed extent, and operates the unloading of the pieces from the selected scales.
