Wheels with "corners" on them may seem useless, but a New York inventor believes such "flat" wheels may replace the track-type drive on military vehicles and tractors. Each driving unit is actually a pair of oval wheels synchronized with their long axles at right angles to each other. This means that the point of one wheel and the flat part of the other are in contact with the ground at the same time.

By Eugene M. Hanson WHEN THE mad scientist in the movies pulls the switch and his fantastic machinery begins to hum and glow, causing flashes of man-made lightning to leap and crackle around the room, you can be fairly certain that Kenneth Strickfaden is somewhere in the picture. Ever since he created the electrical effects for "Frankenstein," Strickfaden's genius has been in great demand among motion-picture producers when spectacular laboratory trickery can be made to fit into the plot. Strickfaden not only created the effects for "Frankenstein," but also doubled for Boris Karloff in sequences which called for million-volt sparks playing over his body. Since then, he has added his wizardry to "Son of Frankenstein," "Bride of Frankenstein," and the other sequels; the "Buck Rogers," "Flash Gordon," "Sherlock Holmes," "Chandu," and "Fu Manchu" featuresâ€”altogether more than 50 movies in the last 15 years.
