Abstract
382,589. Calculating-apparatus. FABRIQUES DES MONTRES ZENITH, Le Locle, Switzerland. June 21, 1932, No. 17549. Convention date, June 24, 1931. [Class 106 (i).] Adding - apparatus.-The varying periods of operation of a machine as recorded on the usual clockdriven record disc b are summed by applying the disc concentrically to a similarly graduated disc a and manipulating the two discs so as to add the lengths of the " in operation " records. The manipulation is assisted by a cursor d carried by an arm pivoted centrally at the back of the disc a. A cylindrical boss c at the centre of this disc permits the application and rotation of the record discs. The results may be read from the disc a in terms of time or of percentages of normal running times.
