General Electric

A short film put out by the Hotpoint Company to demonstrate their Electric Ranges.

Promotional short produced by General Electric for release through Warner Bros. to advertise GE's home appliances.

Training film demonstrating the usage of the turbosupercharger, a device for providing greater engine capability at high altitude. Various techniques for operating and servicing the turbosupercharger are shown using a B- 17 bomber.

A story of the backbone of America's transportation system - the railroad - this film traces the evolution of locomotive power from steam through electric and diesel-electric to the latest super-powered gas-turbine electric. Emphasis is given to the ways in which these developments have kept pace with the ever-growing demands of a nation that today virtually "lives out of box cars." The picture also offers a glimpse of the operational mechanics of the country's complex railway net¬works—accenting the many applications of electricity. The striking color and the non-technical, human-interest approach combine to give this picture high general-audience appeal.

Training film demonstrating the techniques and requirements of flying the B-24 bomber equipped with a turbosupercharger, a mechanism designed to help engines function at full capacity at high altitudes.

Laboratory experiments which later are applied to practical use are detailed here. Among the problems attempted and executed are the preparation of delicate springs from fused quartz and the steps in the manufacture of sodium lamps.

The marvels of the "Electric Eye" scientifically known as the photo electric cell are very entertainingly presented in this industrial from the laboratories of General Electric. A narrator explains everything in popular language.

The fascinating subject of crystal. Narration at footage's outset pointedly conveys that while there may have been little science in the mystic practice of crystal gazing, there is much crystal gazing in modern commercial research science.

Deals with liquid air, magnetic thickness gages, and the cathode ray oscillograph.

The third in the interesting series demonstrating developments in the various fields of science. These reels have a strong appeal for all those of a scientific turn of mind, and the narration is down-to-earth talk that all can understand.

Toothless gears (actuated by magnetism); a photoelectric sorter, for beans; the manufacture of lamps. Well photographed and adequately narrated, this holds interest all through. Especially absorbing is the last section.

Scientific accomplishments: a demonstration of magnets that push as as pull, causing an object to float in the air; "walking oil," which mixes with water; "rickety oil," which causes vibrations in machinery, and useful light beams.
