Book 5 - A. Book 6 - A. Book 7- A. Written by Pascal Garnier. Lafayette Bamboo Slide Rule No. The instruction manuals were rarely ever sold separately from the slide rules and many were lost over time. The project is to provide a composite hard copy book and digital of reprints of restored instructions from the most popular manufacturer's slide rule models.
Cox, , 68 pagesModels: to Mannheims, and 16 and 20 inch Mannheims, Polyphase Slide Rule, and and T Duplex slide rules. Also for newer , Mannheim models with similar scales. Note that Mannheim trig scales use degrees, minutes and seconds. It has 88 pages that describe the uses of slide rules and explain processes for making calculations and locating the decimal point. Breckenridge also discussed the history and theory of the slide rule before providing worked-out examples and exercises for readers to solve.
There are also "advanced problems," material on plane trigonometry and triangles, and problems specific to certain occupations and tasks. This manual was received with MA.
References: Clark McCoy, ed. Breckenridge, The Polyphase Slide Rule , [3rd ed. The cover notes that the company had applied for a patent on a slide rule indicator, but no such patent has been found.
The manual begins with the claim that results on model were significant to three digits. After explaining the parts of a slide rule, the manual divides the process of learning to use a slide rule into twelve steps, each of which are discussed with examples, solutions, and exercises in the remainder of the pamphlet. This manual was received with Its citation information is: Maurice L.
He then explained placing the decimal point; the inverted scales; scales for squares and cubes, logarithms, and trigonometry; and solving problems using multiple scales. He next described the log log scales in a section that has several diagrams of slide rules. A pink paper sheet on caring for the slide rule is inside the booklet.

This page booklet was intended for use with Pickett models 2, 3, and 4. It contains sections on the general operation of a slide rule, the use of scales for trigonometry and roots, elementary vector methods, the use of logarithmic scales, practice problems, hyperbolic functions, and circular functions.
Hartung also showed how the double T scales could solve side-angle-side triangle problems in one step. Model was advertised at the back of the manual, and instructions for caring for Pickett slide rules were provided inside the back cover.

It provides general information on how to use slide rules, including the arithmetical operations, locating the decimal point, combining multiplication and division, using the folded scales, calculating roots, trigonometry, and vectors.

The slide rule depicted inside the manual is Dietzgen's "National," model , and the manual was received with Detailed instructions are provided for reading the scales, multiplication, placing the decimal point, division, proportion, squares and square roots, cube and cube roots, trigonometry, and logarithms. Indeed, the manual indicates portions of it could be used with other Dietzgen slide rules, such as model A. Collections Search Search for Now my kids want to learn to use them for their calc classes.
As the prof doesn't concider them to be real calculators. Young whip should figure out what sent us into space and probably designed the car that he was conceived in. He was one of the lead engineers on the "Manhattan Project". Don't ya think? I have a Deci-lon slide rule with leather case I was thinking about selling and wondering if you would be interested in buying it.
David: Thanks for making the offer, but one is all I "need". I think need is the right word there ;. The one I had was green and purchased in but it needs to be replaced.
Any ideas where I might find a replacement? There may be a rule on sale that's seen better days, but that has a really good case. There are a few slide rule sites online that sell rules an example , but there you'd be paying through the nose for an excellent rule just for the case.
Have not used it since Took it out today to see if I could learn to use it again. Funny to be searching for the old stuff on the inet and getting hits.
Seems to be quite the slide rule. I enjoyed reading about the company history. Regards, Scott PS. I upgraded to an HP29C.
