Description
Предлагаемый прибор дл измерени длин, схематически изображенный на чертеже , состоит КЗ установленной на зеркале дуговой шкалы, по которой .переме-щаетс шарнирно прикрепленный к зеркалу эталон, освещаемый источником параллельных лучей света.The proposed device for measuring lengths, shown schematically in the drawing, consists of a short-circuit arc-mounted arc scale, along which a standard hinged to the mirror, illuminated by a source of parallel light rays, shifts.
Измер емый предмет X кладетс на зеркале 2 так, чтобы один конец его, совпадал с началом линейного эталона а, эталон а поворачиваетс по дуговой шкале 1 до того момента, когда тень эталона а, освещаемого сверху источником света 3, совпадет с концом предмета. При этом образуетс треугольник,-двум сторонами которого вл ютс измер емый предмет X и эталон а. Угол «, образуемый этими двум сторонами, т.-е. эталоном и измер емым предметом, отсчитываетс по шкале 1. Длина измер емого предмета определ етс таким образом из формулы X и Cos а.Measured object X is placed on mirror 2 so that one end of it coincides with the beginning of linear standard a, standard a is rotated on an arc scale 1 until the shadow of standard a, illuminated from above by light source 3, coincides with the end of the object. A triangle is formed, the two sides of which are the measured object X and the standard a. The angle "formed by these two sides, i.e. the standard and the measured object are measured on a scale of 1. The length of the measured object is thus determined from the formula X and Cos a.
Предмет патента.The subject of the patent.
Прибор дл измерени длин, характеризующийс применением подвижного по дуговой шкале 1 линейного эталона «, шарнирыо соединенного с несущим промер емый предмет X зеркалом 2, освещаемым источником параллельных луче света 3.A device for measuring lengths, characterized by the use of a linear standard moving on an arc scale 1, hinged to a mirror 2 carrying a measured object X, illuminated by a source parallel to the light beam 3.
