Door
a wooden or metal, or partly wood and partly metal frame, constructed so as to open and shut on hinges and close the entrance to a building, rooms, etc. The doors of ancient Egypt and contemporary nations swung upon vertical pintles which projected from the top and bottom of the door into sockets in the lintel and threshold respectively. The commonest form of door had the pintle in the middle of the width; so that, as it opened, a way was afforded on each side of it for ingress or egress. Double-margin doors are made in imitation of folding-doors, the middle style being made double with an intervening bead. Sliding-doors are an improvement on folding; they slip into grooves in the partition. A proper-ledged door is one made of boards placed side by side with battens called ledges at the back. With a diagonal piece at the back, in addition, it is said to be framed and ledged.

Doppler Effect
the change in the frequency and length of light or sound ing body on account of the latter's approach or recession. When a body which is emitting such waves is at the same time approaching the observer, the number of vibrations reaching the latter in a unit of time is of course increased; or, in other words, the wave-lengths are diminished, thus altering the color of any light emitted or raising the pitch of any sound. A familiar example of the Doppler effect is the rise of pitch in a locomotive whistle, followed by its fall, as it passes a car window. Doppler's Principle has long been used in astronomy, in connection with the spectroscope, to determine the radial velocity of stars: - that is, the speed with which stars are moving toward or away from the solar system. It has also been used to prove and measure the rotation of the sun and various planets, as well as to measure the orbit of the earth. In the field of sound, the Doppler effect has recently been utilized in a signaling device invented by Mr. Anders Bull, which indicates to receivers the direction of the signal by means of
