Title: Metal ring of core clad with wound wires prodn - with interrupted drive to pack windings for tyre beads
Inventor: LEGER JOSEF
IPC: B29D30/48

Title: Change gear for rack and pinion drive - has meshed segmented gears with electric circuit switching control
IPC: F16H27/08
Filed: 1972-08-16
Abstract: The gear change mechanism has a segmented drive gear, a driven sprocket wheel and a cylindrical stop.

Title: Thyristor cct. for current pulses with fast rise times - has constant voltage cct. bridging saturating choke to avoid thyristor hot spots
Inventor: IIDA TAKAHIKO
IPC: H02M1/00
Filed: 1974-10-23
Abstract: The thyristor circuit for current pulses with fast rise times has a d.c. source charging a shunt capacitor via a resistor. When the thyristor is turned on, this capacitor discharges through a choke and saturating inductor, both in series with it across the capacitor. The slope of the resulting current pulse is improved by bridging the saturating inductor by a constant voltage circuit. During the unsaturated period this constant voltage circuit supplies current that is sufficient to broaden the thyristor initial conduction region. The constant voltage circuit constant voltage circuit consists of a Zener diode and a second diode coupled in series opposition, or it may contain a choke, a capacitor or a resistor. The circuit avoids hot-spots in the thyristor, thereby preventing damage.
