Title: Combined radiation dosimeter - for neutron and gamma radiation with solid state electronic element
Inventor: BROSTROEM DORIS
IPC: G01T1/10
Filed: 1972-05-31
Abstract: The semiconductor component with at least one p-n junction, esp. a diode is sensitive to neutron radiation and the dose is measured in terms of the change in photo-short circuit current before and after exposure. The end of the housing containing the diode has a window of RPL (radio-photo-luminescent glass) whose property is to emit light in the visible spectrum when illuminated with UV light after exposure to gamma radiation. A second, neutron insensitive but visible light sensitive component, esp. a photo diode may be included in the housing. To read out the photo-short circuit current the device is illuminated by a high-pressure discharge lamp through a filter with a passband in the IR region, the RPL glass window being transparent in this region. For measurement of gamma dose, the photo-blocking current of the diode, or of the additional photo-diode, is measured illuminating the cell in this case by the same lamp but through a filter whose pass band is in the UV region.

Title: Quench cct. for electronic photoflash - has thyristor bias capacitor to prevent reignition
Inventor: ENGELSTAETTER HEINZ
IPC: H05B41/32
Filed: 1973-08-01
Abstract: The photoflash circuit incorporates a photocell whose output signal causes the flash to be terminated when a sufficient quantity of light energy has been emitted. The quench circuit uses a series thyristor whose control gate is coupled to the negative side of a capacitor. This capacitor is charged by the photocell's quench signal. The discharge time of the capacitor exceeds the response time of the thyristor by a factor of ten. The negative bias of the thyristor control gate prevents re-ignition particularly during repeated use when the component becomes warm. The biasing arrangement also allows thyristors of a lower rating and widely varying parameters to be used.
