  • Power supply having a voltage monitoring circuit
    Patent number: 8441814
    Abstract: A blocking-oscillator-type converter circuit works with a transformer that has only one primary winding and one secondary winding. The transformer contains no reaction coupling winding for the blocking oscillator. The control voltage for the oscillator is derived from the primary voltage of the transformer, that is, during the free-running phase. Furthermore, a voltage monitoring circuit is provided that works independent of the oscillator, inhibiting the output voltage of the oscillator when the voltage on the output of the blocking-oscillator-type converter is too large. A current monitoring circuit works independent of the oscillator and the voltage monitoring circuit and inhibits the pulses for the power transistor when the current on the output side exceeds a specified amount.

  • Power supply arrangement with output flow monitoring
    Patent number: 8335093
    Abstract: According to the invention, a blocking oscillator type converter circuit functions with a transformator that only comprises a primary winding and a secondary winding. Said transformator does not comprise a return coupling winding for the blocking oscillator. The control voltage of the oscillator is derived from the primary voltage of the transformator during the free-wheeling phase. The invention also relates to a voltage monitoring circuit that works independently from the oscillator, the output voltage of the oscillator being repressed when the voltage on the output of the blocking oscillator is too high. A flow monitoring circuit functions independently from the oscillator and the voltage monitoring circuit and suppresses the impulses for the power transistor when the power on the output side exceeds a predetermined measurement.

  • EXPLOSION PROTECTION HOUSING WITH SIGNALING DEVICE
    Publication number: 20120281419
    Abstract: The invention relates to an explosion protection housing having a threaded opening. A threaded bushing comprising a glass body in the interior thereof is mounted in the threaded opening. The glass body has a diverging lens on the exterior and a converging lens on the interior. A light-emitting diode is present at the focal point of the converging lens. In this manner, that light impinging within the capture region of the converging lens is converted into parallel light passing through the glass body to the diverging lens. The parallel light bundle is converted back into a divergent light bundle by the diverging lens so that the emerging light is visible from a wide angle range.
