Patent CH-678998-A5 (CH)
Inventor: MUEESSLI DANIEL
IPC: H05B41/295
Filed: 1989-10-26
Abstract: To eliminate the drawbacks of prior art preheater circuits in older electronic ballasts for fluorescent lamps, i.e. that they consume power unnecessarily and generate heat throughout the time for which the ballast is switched on, the invention proposes a circuit which is switched off once the fluorescent lamp (FL) has struck. The temperature sensitive resistor (PTC22) in series with a potential balancing capacitor (32) is connected together with a first diode (D1) in parallel via a series oscillation circuit capacitor (C22) and via a second diode (D2) to a high-voltage output (''+'') of the ballast (EVG11). Thus, in a first stage after the ballast (EVG11) has been switched on, the incandescent coils (W1, W2) of the fluorescent lamp (FL) and the resistor (PTC22) which is low-ohmic when cold are heated so that the latter becomes high-ohmic. This means that in the absence of an ignition current between the incandescent coils (W1, W2) the voltage between them rises until it reaches the lamp striking level. After the fluorescent lamp (FL) has struck, the voltage between the incandescent coils (W1, W2) falls to the running level. As this is lower than the voltage at the high-voltage output (''+'') of the ballast (EVG11), no further current can flow from there via the resistor (PTC22). The first diode (D1) prevents current from flowing from the ''out'' output of the ballast (EVG11) via the resistor (PTC22).

Title: Device for activating a needle in a needle-type printing head
Inventor: ROSSOPOULOS STEPHANE
IPC: B41J2/26
Filed: 1982-07-12
Abstract: The device for activating a needle (2) in a needle-type printing head (1) comprises a magnetic circuit (10) and an activating lever (9). The rear end of the needle (2) carries a connector (8) having a groove (24) intended to receive one of the ends of the lever (9) so as to prevent a rotation of the needle about its axis. When the printing head is mounted, the grinding and deburring operations are thus greatly facilitated. The groove (24) also provides perfect centring of the lever (9) and makes it possible to reduce the plastic flow of the connector under the repeated impacts of the lever. <IMAGE>
