We use Optical Character Recognition (OCR) during our scanning and processing workflow to make the content of each page searchable. You can view the automatically generated text below as well as copy and paste individual pieces of text to quote in your own work.

Text recognition is never 100% accurate. Many parts of the scanned page may not be reflected in the OCR text output, including: images, page layout, certain fonts or handwriting.

Fig. 6. "Static" single exposure of spherical charge in firing position to show line structure. photoelectric pickup which receives a signal from the first light radiated from the event. This signal is then fed through a variable time delay which pulses the shutter at any selected time after the first burst of light. A large amount of light is lost in this shutter through polarization and absorption in the glass slug. The physical size of the slug further reduces the aperture of the system. This light loss is tolerable since the luminosity of most explosive phenomena is very high. The Faraday unit is highly portable, simple to operate, and has given continuous trouble-free service. In these respects it is superior to similar 1-jusec Kerr cell shutters which operate on the principle of birefringence displayed by nitrobenzene under an impressed electrostatic field. High-Speed Motion Pictures (Grid Framing Camera). The ultra-high-speed camera, which was developed specifically for use in the study of explosives, has been described in considerable detail in an earlier Journal.* However, as a matter of review, the principle of multislit focal-plane scanning7 on which this camera is based is described below.
