g Exposition By KEN COY and CHUCK ZUEGNER ONE OF THE HIGHLIGHTS of the year for the School of Engineering is the annual exposition. Here, machines and engineers run rampant in a three-ring circus of zany ideas. impair in a three-ring circus of zany feats "Engineer's Day" began in 1909 and has since brought thousands of visitors to the University. Generally, students think up and prepare for display many of the gadgets, and this year promises to be the best yet. Included among the more choice items at the exhibit are a wonder-producing mechanical brain and an electronic device that performs miracles with a pan of cookies. WHAT HAVE WE HERE?—One of the newest additions to the University is this Philips electron microscope in Lindley hall. This microscope is able to magnify up to 60,000 times the original size of an object. The machine, the only one of its kind in Kansas, is operated by Ada Swineford of the Geological Survey. BAKE ME A CAKE—Maurice Hamm and Larry Kravitz, juniors, test a Westinghouse industrial RF generator, which can bake a cookie (and sometimes burn it) in 20 seconds. MIDGET-SIZE CAMPANILE—A tubeless organ will be played for lovers of incongruous music at the electrical engineering department's exhibit. It's eight keys produce tones by "a series of transistors in an oscillating circuit." ARABELLA II—The Tic-tat-toe machine was build by electrical engineering students. P.K.Smith, senior, and Larry Kravitz, junior, challenge the complicated mechanism even though they're aware it can't be beaten. PROP AND THE JET—The Cessna-140 is the first University-owned aircraft. Procured in a trade, aeronautical engineering students reconditioned it. Current plans call for using it in experimental work as well as for teaching purposes. The Cessna and other heavy aeronautical equipment are housed in the University's hangar at Lawrence airport. Shown here at the right is a XJ31-5 turbo-jet engine. It was built by General Electric and given to the department by the Navy. Norman Hoecker of the aeronautical engineering staff points out features of the engine to engineering seniors Jerry Hollenbeck and David Wong.
