Description

Известные вычислительные приборы в виде р да поворотных вокруг общей оси дисков, несущих логарифмические или иные щкалы, сложны в работе и не позвол ют производить расчеты с числом переменных разным удвоенному числу дисков.Known computing devices in the form of a series of rotary disks around a common axis carrying logarithmic or other codes are difficult to operate and do not allow calculations with the number of variables to be twice the number of disks.

Описываемый логарифмический вычислительный прибор позвол ет устранить указанные недостатки.The described logarithmic computing device eliminates the indicated disadvantages.

Схема прибора изображена на чертеже.Diagram of the device shown in the drawing.

Прибор содержит набор дисков 7, 2, 3 разных диаметров и прозрачный визир 4. Диски поворотно насажены на одну общую ось 5, несут логарифмические щкалы и номограммы и снабжены дуговыми вырезами и дуговыми окнами, которые позвол ют производить отсчеты по шкалам и номограммам, вынесенным под выщележащими дисками.The device contains a set of discs 7, 2, 3 of different diameters and a transparent viewfinder 4. The discs are rotatably mounted on one common axis 5, carry logarithmic lathes and nomograms and are equipped with arc cutouts and arc windows that allow you to read on scales lick discs.

Предмет изобретени Subject invention

Логарифмический вычислительный прибор, содержащий набор поворотных вокруг одной общей оси дисков, имеющих разные диаметры и несущих логарифмические щкалы и номограммы, отличающийс  тем, что, с целью производства расчетов с числом переменных равным удвоенному Числу дисков и их упрощени , диски снабжены дуговыми вырезами и дугоеыми окнами, позвол ющими производить отсчеты по шкалам и номограммам, нанесенным под вьштележащими дисками.A logarithmic computing device containing a set of rotary disks around a common axis, having different diameters and carrying logarithmic buttons and nomograms, characterized in that, in order to perform calculations with a number of variables equal to twice the number of disks and their simplification, the disks are equipped with arc notches and arc windows allowing for reading on scales and nomograms deposited under the overlapping disks.
