THE NEW LOGRING
Digital Graph Plotter
THE LOGRING DIGITAL GRAPH PLOTTER automatic-
ally plots one variable against another algebraically in incremental steps, in response to electrical impulses. It is ideally adapted for use as a read-out device for electronic digital computers, especially digital differential analyzers, and for use in connection with such problems as aircraft tracking and automatic data reduction.
• plots at speeds up to 20 steps per second, in incremental steps of 1/64 of an inch.
• simultaneous movement on both axes in either direction.
• can be controlled electronically or by external or remote switches or relays.
• will make several carbon copies or duplicating stencil.
• instant manual positioning of pen and drum.
• takes 12″ x 18″ paper or continuous 12″ strip.
Mechanical simplicity ..high reliability ..digital accuracy ..quick pen cartridge change..self-contained power supply.

It seems to me that anyone who would use the phrase “Getting Closer to Infinity” does not really understand the concept of infinity.

GETTING CLOSER TO INFINITY
Businessmen, engineers, and scientists now are solving problems in scientific and industrial data processing which, a few short years ago, would have been considered well-nigh infinite.

IBM Electronic Business Machines are making an important contribution to this progress. These machines accomplish once-overwhelming tasks with incredible speed and accuracy … freeing thousands of valuable minds for creative effort.

Dissatisfaction- AMERICA’S GREATEST ASSET

Opportunities to create better products exist in every home and industry in America today. But only a few, dissatisfied men and women recognize these opportunities. Such leaders are advancing their respective industries. They possess vision. They are spurred by initiative. Feather dusters have no place in their planning.

Since 1938, Meletron has been producing excellent instruments that are used by every major aircraft manufacturer. But we are constantly testing new materials and devising new methods. Leadership in this industry imposes the obligation to improve, because tomorrow’s standards will be higher. Dis-
satisfaction with what has been accomplished, plus a determination to improve, is America’s greatest asset.

For all you us sci-fi nerds out there.

YOU are an EARTHMAN..

Whew, now I know where to go for all of my high-voltage ionizing radiation needs. Thank you High Voltage Engineering Corporation!

because . . .

The ionizing intensity of its electron beam, at 2 MeV, is several thousand-fold greater than the most powerful radioactive sources now available. The same accelerator will deliver 5000 roentgens per minute of x-radiation at 10 centimeters.

The cost of radiation energy from a Van de Graaff, in terms of gram-rep in the irradiated material, is only a tiny fraction of the costs associated with natural or artificial radioactivity.

The electron or x-ray beam from a Van de Graaff is fully controllable in direction and shape, permitting efficient utilization of energy output.

Your specific questions about Van de Graaff equipment will be answered fully and promptly. Our experience in applied radiation energy is at your disposal in planning your research program.
