Abstract: A pneumatic control device for automatic charging of containers placed on a weighing machine with one or more substances. The control device comprises a manually operable starting valve actuating a delay circuit to operate the weighing machine. After this, a delay circuit together with a shutoff valve controlled by the weighing machine and arranged in a weighing valve circuit actuate a main valve in one of the supplying conduits, selected by an alternating or selecting circuit. Having charged all the determined substances the control device is reset to the initial position by a reset circuit giving an impulse to the starting valve.

Abstract: A pressure gauge comprises a housing, a main chamber in the housing partly filled with a liquid and a body floating in the liquid. A portion of the body extends through an opening in the housing. A fluid to be measured is introduced into the chamber above the liquid and its pressure is exerted on the surface of the liquid thus causing the body to assume a floated position. A scale is provided outside the housing and the position of the body, and thus the pressure in the measuring chamber, is indicated by the position of the body portion relative to the scale.

Abstract: A weighing device for weighing predetermined amounts of materials sequentially introduced into a container which contains residual amounts of the materials. The device includes scale means to set the counterweight on a balance arm such that the arm will balance when the correct amount of a first material is added to the container. The device further includes scale means to add an increment of moment to the balance arm when the arm is in a balanced position after introduction of the correct amount of the first material. The increment of moment added corresponds to the amount of the second material required to be added to the container and this amount is indicated when the arm is rebalanced. The scale means comprise a wheel operable to add moment to the arm in an amount indicated by a scale on the periphery of the wheel. The wheel is movable relative to a fixed scale which indicates the measured residual quantity of the second material in the container. A ring is mounted on said wheel and contains a third scale indicating the correct amount of the second material.
