The slits are produced by spaced circular slicing blades located in a V-shaped support on which the tampon is placed, so that rotation of the blades results in the production of the slits (see Fig. 7). The apertures are made by an elongated sharp object having a diameter between 1/32 and 3/32 inches. A withdrawal string secured by gluing, looping or sewing, is provided.

Initially, thyristors 14 and 15 are turned on so as to charge the commutation capacitors 19 and 20 to a first polarity after which thyristors 15 and 14 are self-extinguished. Thyristor 21 is turned on at the end of each commutation period. In order to commutate the current from the main thyristor 23 to the main thryistor 24, thyristor 11 is turned on so that capacitor 19 is discharged via thyristors 21, 11, turning off thyristor 21. Thyristor 18 is now turned on to discharge capacitor 20 via thyristor 18, diode 30, thyristor 23 and via thyristor 18, diode 32, thyristor 25 and via thyristors 18, 28 and diode 33. The main thyristors 23, 25 and 28 are thus turned off. The current via diodes 29, 31 and 34 recharges capacitor 20 with reversed polarity. The appropriate main thyristors are then retriggered. An optional pair of thyristors 61, 62 and optional source of commutating voltage 60 is provided for use when the adjustable supply 10 has a low voltage. In Fig. 4 (not shown) a commutating inductor is connected in series with each of thyristors 11, 14, 15, 18 and a further inductor in series with thyristor 21.
