Electric CAMERA Works Without Film
SELENIUM, that wonderful metal that changes its electrical resistance upon exposure to light, has recently been used in a most revolutionary camera developed by Mr. K. Wilcke, German scientist. In the ordinary sense of the term, this experimenter uses no film, and entirely dispenses with the use of silver compounds.

Make Street Intersections PAY a PROFIT
RECORDS show that busy street intersections are the favorite spots in which traffic accidents occur. To eliminate these danger spots, J. G. Van Zandt, an engineer of Pittsburgh, Penn., has patented the idea of a safety-tower which practically eliminates the possibility of crossing collisions and at the same time returns a profit to the community. Space above and below street level at intersections belongs to the city. Mr. Van Zandt's towers would be constructed at the intersection, as shown in the drawing below, and would contain stores, offices, and parking facilities which would return a handsome revenue to the builders.

Electric Camera Photographs Walls of Human Stomach
A NEW wonder in photography that will take pictures of the innermost recesses of the human stomach has recently been developed by three doctors of the University of Vienna. This amazing device, shown on the right, takes eight pictures simultaneously. The new camera is contained in a tube 1/2 inch in diameter and three inches long. The powerful light is operated by a battery with cables running down the throat to the filament, as shown in the drawing.

Home Movies From Phonograph Records
PLAY a moving picture from a phonograph record! When Baird, the English television experimenter, suggested this system several years ago, he did not realize how soon it would be before his prophecy would come true. Those who have listened to television programs know that the signals become audible in the form of a shrill whistle in the loudspeaker. This whistle carries the picture elements in the form of modulated sound.

"Balloon Cops" May Clear Traffic Jams
THE traffic tangles caused by major football games has become a problem of great importance to those cities that have the larger stadiums within their bounds. For hours before and after the games the police are compelled to work at top speed to restore the normal movement of traffic, being called upon at times to handle some fifty thousand additional cars. At the various traffic conventions held about the country this problem has received much attention but it was only recently that a plausible solution to the matter was offered.

Water-Foils Support HYDROVANE Ship
FOR years builders of ocean liners have been refining the designs of their vessels until it seems that the ultimate speeds attainable by the conventional hulls have just about been reached. Promise of ocean speeds approaching that of fast airplanes is held forth, however, by a modified hydroplane type of sea vessel designed by H. G. Allan of Glasgow, Scotland, and illustrated in the drawing below. As shown, the unique craft is essentially a streamlined hull supported on steel hydrovanes. These hydrovanes, planes, or water wings, as they may be described, travel through the water, but virtually on the surface. Ordinary hydroplanes, which are designed to avoid wave-making resistance, attain remarkable speeds but are unseaworthy in rough water.

Electric Cannon Uses No Gunpowder
SILENT guns sending their whistling messengers of death into the sky at speeds far beyond those now attained by powder-driven shells seem likely for the next war, using for propulsion magnetic fields so powerful that when they are short-circuited they produce miniature earthquakes. Dr. Kapitza, F. R. S., working at the Cavendish laboratory of Cambridge University, England, in his attempts to disrupt the atom has produced magnetic fields so powerful that they "explode" the coils that produce them. This man has finally revealed the secret of the magnetic gun so long anticipated by ballistic experts. Dr. Kapitza accomplishes the electric firing of a shell by short-circuiting powerful dynamos for periods of one one-hundredth of a second.

Build a (rather bad) Salmon Can Fax Machine
A COUPLE of sardine and salmon cans, a few bits of brass and several pieces of wood are all the materials that are needed to assemble an experimental but very practical picture transmitter and receiver. Two of each of the cans will be needed. The salmon cans should be of the small or half can size and the end that has been opened should be replaced by soldering in water tight, a new disc of tin.

New Inventions that Baffle Crooks
by Lew Holt Inventors working in the cause of law and order, inspired by a recent outbreak of outrageous kidnapings and other crimes, have perfected numerous devices which give the police a new advantage in the perpetual war on criminals. Crime weapons are fully discussed here. COULD the immortal shade of Sherlock Holmes return to earth, he would find a new delight in using the latest weapons of science to wage war on criminals—criminals, incidentally, of such perverted genius and "big business" organization as to make the notorious Professor Moriarty of Holmes and Watson fame a decided back number.

Dynosphere AUTO Runs on One Wheel
THE wheel is one of the oldest inventions of man and has been used for ages on all sorts of vehicles, but it has remained for an English inventor to build a complete vehicle out of one wheel. As shown in the photo above, the "dynos-phere," as its inventor calls it, consists of a wide-rimmed latticed wheel with a power plant inside its circumference, where the driver sits. There is also room for a companion in the seat alongside him.

Modern Methods Improve Ancient Tattooing Art
TATTOOING is one of the most ancient arts in the world. Even before man had learned to write—and centuries before he could print—he practiced the art of pricking various designs and symbols and pictures into the human skin. Down through the ages men and women have tattooed themselves for a wide variety of reasons. Early tribes tattooed their faces to make themselves appear more ferocious and powerful in battle. Other tribes tattooed their whole bodies as a protection from the rays of the sun and from the eyes of their enemies. Then the custom sprang up of tattooing the various parts of the body for religious purposes, or to show membership in a certain family or clan, or to make themselves more attractive to the opposite sex, or as evidence that a youth had reached the marriageable age.
