Curta Inlroduces Compoct Golculotor

Type 2 Curta calculator is a new lightweight calculating machine introduced by the Curta Company for architects, contractors, estimators, field engineers and surveyors who require a precise "on-the-spot" answer for every type of mathematical operation.

Combining the accuracy, speed and versatility of a large desk calculator with the portability of a pocket slide rule, the Curta has a capacity of ll digits on the keyboard, 8 digits on the indicator dial and 15 digits (corresponding to 999 trillion) in the answer dial.

The cylindrically shaped Curta is only ZXc inches in diameter by 3% inches high, about the size of a fishing reel, and weighs 12 ounces. Easily held and operated in one hand, the Curta does not require an external power supply.

The main barrel assembly contains the ll digit horizontal keyboard with color coded setting knobs and movable white decimal markers. A number set on the keyboard remains unaltered until a calculation is completed.

A driving axle with the unique step drum and reciprocal cog system passes through the center of the machine and is actuated by a short radius operating handle designed for high speed operation. The knurled carriage contains the revolution counter, result dial and additional decimal markers. A single lever will clear the two dials, either simultaneously or individually.

A continuous tens transfer and reversing lever permits short-cut techniques in the basic operations of multiplication, division, addition, subtraction and in multiple operatirons involving cubes, roots, percentiles and trigonometric functions. Automatic stops prel'ent errors in operation or damage from overspeeding in fast operation.

The Type 2 Curta is supplied in an attractive dust and shockproof metal container and is guaranteed for one year. Available from: The Curta Company, 14435 Cohasset Street, Van Nuys, California.
