Embodiments of actuators comprise an electromagnetically conductive housing ; a rotor ; a first stationary pole member ; a second stationary pole member ; a first permanent magnet connected to the first pole member ; a second permanent magnet connected to the first pole member ; and; an electrically conductive coil situated within the housing and configured to define a cavity. A suitable automated or human-operated process is utilized to generate an appropriate power value of a fractional Fourier transform correction operation. The invention includes a compound of formula, Y represents C or S; R represents an allyl group or a radical. The means to supply the electrical current to the faulted coil includes one or more un-faulted electrical phases of the electrical machine. The upper end portion of the bag is supported between mating faces of the lids. In a modified embodiment instead of pushing against the cap, a portion of the cap is rotated on the bottle threads to discharge a substance to be infused from the cap into the bottle.
