Abstract
A hydraulic recalculating cell has a substantially vertical inlet portion, an inclined portion connected by its lower end with a lower end of the inlet portion, a further substantially vertical portion connected by its upper end with an upper end of the inclined portion above the first connection, and a divider including two downwardly open pipes connected with the further pipe.
Claims6
A hydraulic counting cell, comprising
- an inlet portion arranged for receiving a plurality of drops of a liquid sucessively after one another and having a substantially vertical portion and a lower end;
- an inclined portion having upper and lower ends and forming a short leg of a siphon, said lower end of said inlet portion being connected with said lower end of said inclined portion at a predetermined height so that the drops of liquid pass into said inclined portion from said inlet portion;
- a further portion having a substantially vertical axis and upper end lower ends forming a long leg of the siphon, said upper end of said further portion being connected with said upper end of said inclined portion at a height exceeding the first-mentioned height so that the drops of liquid pass into said further portion from said inclined portion;
- and
- a flow dividing portion including two pipes with upper ends connected with said lower end of said further portion so that the drops of liquid pass into said flow dividing portion from said further portion, said two pipes also (and) having open lower ends so as to discharge the drops of liquid and to form an outlet of the cell, whereby during passage of the drops of liquid they are successively counted in accordance with their position in said portions.
2 more elements
A hydraulic recalculating device, comprising
- a plurality of hydraulic counting cells each having an inlet portion arranged for receiving a plurality of drops of a liquid successively after one another and having a substantially vertical portion and a lower end, an inclined portion having upper and lower ends and forming a short leg of a siphon wherein said lower end of said inlet portion is connected with said lower end of said inclined portion at a predetermined height so that the drops of liquid pass into said inclined portion from said inlet portion, a further portion having a substantially vertical axis and upper and lower ends forming a long leg of the siphon wherein said upper end of said further portion is connected with said upper end of said inclined portion at a height exceeding the first-mentioned height so that the drops of liquid pass into said further portion from said inclined portion, and a flow dividing portion including two pipes with upper ends connected with said lower ends of said further portion so that the drops of liquid pass into said flow dividing portion from said further portion, and said two pipes also having open lower ends so as to discharge the drops of liquid and to form an outlet of the cell, whereby during passage of the drops of liquid they are successively counted in accordance with their position in said portions, said hydraulic counting cells being arranged one above the other so as to allow a liquid flow from each upper cell to a neighboring lower cell.
