Abstract: The invention concerns a nut provided with a locking element (4, 5, 6, 7), which by e.g. a screw (8, 9, 10, 11) can be urged radially against a screw thread. In order to provide a self-contained and easily releasable nut the locking element is arranged in a recess which, together with the element, is so arranged that at least a part (12, 13, 14, 15) of the element is deformed elastically when the element is moved against the screw thread. Thereby the element springs out of contact with the thread when the screw (8, 9, 10, 11) is released.

Abstract: The winding winds in the outer parts (13, 15) are so adjusted that they provide a suitable heating voltage to the cathodes (17, 18) where the central winding (14) gives a voltage during the tube (16) ignition voltage which is essentially higher than its burn voltage. The transformer is firstly fed with a low current strength which heats the cathodes (17, 18) without starting the discharge, and the current strength after a time delay is raised by jumps so that discharges starts, whereby the tube (16) burn voltage via the transformer regulates the voltage over the cathodes (17, 18) to an essentially lower value. The time delay for the higher current strength is controlled by a heat-sensitive circuit which monitors the light tube temp.

A pinking sensor detects pinking from the combustion process and in proportion to the pinking intensity produces an actual pinking signal from each combustion event. A signal correcting circuit reduces the integrated actual value of the ion flow signals dependent upon the intensity of the pinking signal. A control unit (10) continuously varies at least one regulating parameter in accordance with a regulating algorithm stored in a memory. This algorithm maximises the corrected integrated actual value of the ion flow signals.

Abstract: In a continuous mode flyback converter having a synchronous switch (Q2) the drive pulse to the switch (Q2) on the secondary side is generated by an inverting buffer circuit being fed from the output voltage terminal. By using such an arrangement several advantages are obtained. Hence, the pulse generating circuit arrangement generates a drive signal to the synchronous switch which is independent of the input voltage and the drive losses can thereby be minimized.
