The mechanism is used to determine the product x*sin(α)*(1/cos(β)). A quantity proportional to sin(α)*(1/cos(β)) is entered by cams 12 and 13 which rotate about fixed axes D-D and E-E. This value is indicated by strip 4 which travels in the directions shown by the arrows. Strip 4 has a special pin b which slides along the groove of channel member 7. When strip 4 moves, member 7 turns about axis B of roller a. At this, member 8 is displaced a distance proportional to sin(α)*(1/cos(β)). Quantity x is entered by means of handwheel 9 which traverses gear rack 10 through a train of gears. Channel member 7 is thereby turned by roller a and the member acts on pin b of strip 4 so that member 8 is displaced a distance proportional to x. Thus, the resultant displacement of member 8 is proportional to the product x* sin(α)*(1/cos(β)) and is transmitted by rack pinion 11 to the actuating mechanism.
