Title: Producing high voltage pulses
IPC: H03K3/55
Filed: 1981-04-16
Abstract: A pulse generator, particularly for pumping a gas laser, comprises a transformer of which the primary is supplied with current via a control switch so that, when the switch is opened, a voltage pulse appears at the transformer secondary and is transferred via a diode to a capacitor. A further switch such as a thyratron or spark-gap switch discharges the capacitor to produce the output pulse. To control the energy transferred from the transformer, which may be an auto-transformer, to the capacitor, the current supplied to the transformer primary is monitored and the control switch opened when that current has reached a predetermined value. The energy for driving the further switch is obtained by discharging a capacitor, which capacitor receives stored energy via a further diode from the transformer primary winding. <IMAGE>

Title: A method and an arrangement for the removal of waste material in rotary punching
Inventor: ANDERSSON THORBJORN
IPC: B26D7/18
Filed: 1983-11-30
Abstract: In the rotary punching of a moving material web the punched out waste material has to be removed so as not to interfere with the course of the punching. This can be done with the help of vacuum and internal ducts in the female roll, but this method cannot be used at high working speeds because of the centrifugal force. Instead of this in accordance with the invention the die hole (5) of the female roll (2) is provided with pistons (7) forming a seal which are manoeuvred to and fro in rhythm with the rotaton of the roll. As a result the punching waste (6) is retained for only a short while after the punching and is ejected thereafter and carried away via an external suction arrangement (14).
