Title: Erwin F. Shrader: Innovator in Thermoluminescence Dosimetry
Introduction
Erwin F. Shrader is a notable inventor based in East Cleveland, OH (US). He has made significant contributions to the field of thermoluminescence dosimetry, holding 2 patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of his latest patents is the TLD card reader. This device comprises infeed and outfeed carousels for sequentially indexing cartridge holders for stacks of TLD cards to infeed and outfeed stations. It features a shuttle transport that sequentially transfers TLD cards from the infeed station to a card read station and then to the outfeed station. At the read station, plural photomultiplier tubes are mounted in opposition to respective hot fingers, which are independently adjustable along three axes and biased for engagement with respective TL elements in a TLD card. For photomultiplier tube calibration, a shuttle assembly is operable to move reference lights into the path of the shuttle transport for alignment with respective photomultiplier tubes. Additionally, a light seal of star-like cross-section is provided to seal the shuttle passageway at the read station. Another innovative aspect of his work is a TLD card reader that does not require the removal of the cards from their holders. This design includes a holder transport for successively transferring holders from an infeed to an outfeed station and a TLD card transport featuring flexible tongues for transferring a card from a holder to a read station and then back to the holder.
