Abstract: A self adjusting device interposed in the lever system of a friction clutch is disclosed. The device operatively connects a threaded adjusting ring and an axially shiftable actuating collar such that wear occurring in the friction surfaces of the clutch is automatically taken up during operation of the clutch. The self adjusting device includes a mounting bracket secured to the clutch cover. The mounting bracket includes a central U-shaped portion and a pair of flange portions, each extending outwardly from an end of the opposing sides of the U-shaped portion. A pin is retained in the opposing sides of the U-shaped portion of the mounting bracket. The pin rotatably carries a pair of hub members which effect the self adjustment of the clutch to compensate for wear of the friction surfaces. The U-shaped portion of the mounting bracket permits visual confirmation of correct installation and function of the self adjusting device.

Abstract: The invention constitutes a supplement to patent application No. P 31 34 883 and to patent application No. P 32 08 088. It relates to the electronic switching-off of the correction circuitry in the event of a large dwell angle and simultaneously maximum correction value.

The capacitor at which the sawtooth-shaped signal is generated is discharged by means of this output pulse such that there will not be any further correction of the control signal.

Abstract: An ignition system for a fuel burning engine has a transformer with a primary winding (L1) and a secondary winding (L2). A magnetic pulse time (20) provides a bipolar signal to the input circuits of a pair of transistors (Qa-Qb, Qn-Qp, Q2-Q3, Q4-Q5, Q6a-Q7) of opposite conductivities.

Transistor pairs of the multijunction, unijunction and field effect Darlington or non-Darlington types may be utilized.
