Blast Effects Due to Reflected Shock Waves
Blast waves are reflected from solid surfaces but not in the same manner as sound and light waves are reflected. When a bomb is detonated at some distance above the ground, the shock wave spreads out almost spherically until it strikes the ground. This initial wave, called the incident wave, is reflected by the ground surface. At a certain distance along the ground, from the point immediately below the bomb, the reflected wave combines with the original or incident wave to form a third wave...

BetaRay Autoradiography for the Study of Metals and Minerals on Microscale is
Betatron is an x-ray-producing apparatus consisting essentially of an electromagnet and a donut -shaped vacuum tube placed between the pole faces of the magnet. The supply of electrons is released inside the vacuum tube from a glowing filament and, under the influence of the alternating magnetic fluj spin around the tube. During this rotary movement the electrons are accelerated by magnetic induction instead of by direct application of high potential as is done in the more conventional types of...
Black Powder Modifications
A modification of BkPdr, known as Brown-, Cocoa-, or Chocolate Powder so named because of its brownish color was invented in Germany ca 1882. It contained K nitrate 79, brown charcoal contg ca 2 HgO 18 amp sulfur 2 and was made in the form of prisms. The brown charcoal was prepd by incompletely charring a light wood or straw and hence contained more volatiles than black charcoal. The compn of Brown Pdr was kept secret until the Russians published in 1886 the formulation of their own powder...
