Abstract
This invention relates to a weight measuring balance especially adapted for the proportioning of a liquid product mixture from cumulative formulas expressed in weight. The balance comprises a pan borne by a centrally fixed stress gauge captor, mounted upon a fixed frame and which furnishes a signal representative of the load's weight, whatever may be the position of the load on the pan, to a measuring device carrying out the display of the weight thus detected on a first display device. The invention is especially applied to the formulations of paints used in automobile body shops from cumulative formulas expressed in weight.
Claims5
A weight measuring balance for proportioning a liquid product mixture from cumulative formulas in weight furnishing the weight of each of the products added, cumulative with the weight of the products previously added, including a pan supported by a gauge which furnishes a signal representative of the weight of the load, comprising:
- a. a first display for displaying the weight detected by said gauge, which is equal to the weight of the load of materials already on the pan;
- b. a keyboard on which is entered the weight of a new cumulative weight of products to be on said pan, which is indicated in the cumulative formula, which weight corresponds to the sum of the quantity of products already loaded, plus the quantity of the new product to be loaded;
- c. means for subtracting the weight of the products already loaded on said pan from the new cumulative weight of products to obtain only the weight of the new material or product to be loaded;
- d. a second display for initially displaying the weight of the new material or product to be loaded as determined by said subtracting means;
- e. means for displaying on said second display a decreasing value from the initially displayed value of said second display in terms of the quantity of products loaded on the pan, so that a return to zero of said second display indicates that a given quantity of product has been loaded;
- and
- f. a signalling means for allowing a visual indication of the approach to zero of the weight of the quantity which should be loaded on said pan.
