"Unitas is the trade name for the Tim equipped with a double counting mechanism, designed by the engineer Robert Rein"
"The reversing levers, positioned to the left of the setting slides, are capable of setting both counting mechanisms to addition or subtraction, or of setting either one to add while the other subtracts. This considerably increases the applicability of the machine. It is possible to simultaneously subtract a result, computed in the first result mechanism by multiplication, from a given value in the second calculating mechanism. "
