  • Patent number: 9320817
    Abstract: The invention relates to an irradiation apparatus for inactivating pathogens and/or leukocytes in a biological fluid such as a platelet suspension and/or plasma comprising: a casing (2), a support member (3) for carrying at least one irradiation bag (19) containing the biological fluid, a light source (4) comprising two banks of light (5, 6) disposed above and below the support member (3), and an agitating system (25) for moving the support member (3), the light source generating UVC light of suitable intensity to inactivate pathogens and/or leukocytes and the agitation system moving the support member in an orbital path with predetermined amplitude and rotational frequency suitable to expose the whole biological fluid to UVC.

  • Patent number: 5604476
    Abstract: A protective device for an electrical consumer disposed in a consumer circuit. The protective device has sensor elements for detecting an operating state of the electrical consumer, and an electronic evaluation and control unit operatively connected to the sensor elements for evaluating and controlling the operating state of the electrical consumer detected by the sensor elements. The protective device further includes a protective switch responsive to the operating state of the electrical consumer for interrupting the consumer circuit. The protective switch comprises a control circuit including a bimetallic strip and a temperature-dependent resistor for deflecting the bimetallic strip for interrupting the consumer circuit, the bimetallic strip thereby defining a deflecting direction. The protective device further includes a power supply unit for supplying electrical power to the sensor elements, the evaluation and control unit and the protective switch.
