Description
В цел х,улучшени видимости де .лений шкалы, покрываемых кра ми .лупы, последней придана форма шарового сегмента, переход щего по плавной вогнутой поверхности в плоскость стекла, служащего основанием лупы.In order to improve the visibility of the scale deformations covered by the edges of the loop, the latter is shaped into a spherical segment that passes along a smooth concave surface into the plane of the glass that serves as the base of a magnifying glass.
Изображенна на схематическом чертеже лупа служит дл отсчета по шкалам с очень мелкими делени ми например, логарифмической линейки. Выпукла форма лупы по кра м переходит в вогнутую, при чем последн вогнута поверхность постепенно лереходитв плоскость, параллельнуюThe magnifying glass depicted in the schematic drawing is used to read on scales with very small divisions, for example, a slide rule. The shape of a magnifying glass is convex at the edges and becomes concave, with the latter concave surface gradually leading to a plane parallel to
задней поверхности ,лупы, образу кра смотрового стеклышка, например , логарифмическЪй линейки.the back surface of a magnifying glass to form the edge of the sight glass, for example, a slide rule.
Предмет патента.The subject of the patent.
Лупа дл отсчета по шкале, например , логарифмической счетной . линейки , характеризующа с , что в средней своей части она имеет выпуклую форму, котора по кра м переходит в вогнутую с тем, чтобы затем постепенно перейти в плоскость , параллельную задней плоской поверхности лупы.A magnifying glass for reading on a scale, for example, a logarithmic counter. ruler, characterized with that in its middle part it has a convex shape, which at the edges turns into a concave so that then gradually go into a plane parallel to the rear flat surface of the magnifying glass.
