Abstract: 297,431. Naamlooze Vennootschap Machinefabriek der Firma P. M. Duyvis & Co. Sept. 21, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Electric push-button systems.-In an electric lift system if the cage does not stop accurately in the plane of the desired floor, an auxiliary circuit is closed automatically by which the hoisting motor again is set in operation until the cage is in alignment with the floor when this circuit is interrupted automatically. At each floor a contact rail b is provided and is engaged by a sliding contact c on the cage. Each rail b consists of mutually insulated contact strips b', b<2>, b<3>. The length of the strip b<2> is equal to the permissible difference of level between the floor of the cage and the floor, and when this strip is engaged by the contact the motor is cut out. When the contact c engages either of the strips b<1>, b<3>, the auxiliary circuit is completed and the motor is actuated. A time relay R<1 >keeps the auxiliary circuit open as long as a current flows through the normal control circuit. A relay R<2> prevents the cutting-in of the motor by the normal control circuit if a floor door, or the cage door, is opened. This relay is short-circuited when the auxiliary circuit is closed by the contacts c, b<1>; c, b<3>. A relay R<3> prevents the motor from being cut in by the actuation of a push-button before the cage is positioned correctly. The upward and downward movement of the cage is controlled by reversing magnets M<o>, M<n> which work with delay action in such a manner that the relay R<1> works with less delay action than the relay R<2> and the latter with less delay than the magnets. A disc-shaped floor-switch d makes a revolution for each journey up or down of the cage and is provided with reversing switches d<1> - - d<4>.

Two magnetic amplifiers are used to feed driving pulses to a selected line of cores in a magnetic matrix-store. The cores of the magnetic amplifiers and of the matrix have rectangular hysteresis loops. Each of the storage cores M1, Fig. 1, represents a line of cores in a three-dimensional matrix. Each line of cores is linked by two conductors 10, 11. The conductors 10 interconnect the horizontal and vertical leads 15, 12 of one set of drive leads and conductors 11 interconnect the leads 24, 27 of a second set. The conductors 10, 11 include oppositely-poled rectifiers D1, D2. Power windings, such as 18, of the transductors shown, normally have a high reactance which is reduced when the control windings are energized. Core 10 is selected when control windings 36 and 39 reduce the reactance of power windings 18, 21 of the associated amplifiers during positive pulses from source PP-1. Current through conductor 10 is inhibited during a negative pulse and the core 10 is set during the following positive pulse. The core 10 may be set to the opposite polarity by the amplifiers with power windings 30, 33. In this case, the transductors are set during a positive pulse and the core 10 is set during a negative pulse. In Fig. 2, saturable transformers are used as amplifiers, the primaries 63 to 68 of one set being connected in series to the pulse source PP-2. In Fig. 3 (not shown), each storage core is controlled by one transductor and one saturable transformer.
