Description
Предлагаема масштабна линейка дл отложени рассто ний при съемочных работах изготовл етс из органического стекла или другого прозрачного материала с масштабом, нанесенным на нижнюю плоскость линейки во избежание параллакса. Рассто ние при этом откладываетс по концевому срезу линейки, наложенной на линии направлени , прочерчиваемой на планшете после визировани кипрегел наколом бумаги при помощи остри циркул или игольчатого наконечника карандаша.The proposed scale ruler for the deposition of distances during survey work is made of organic glass or other transparent material with a scale deposited on the lower plane of the ruler in order to avoid parallax. The distance in this case is deposited along the end section of the ruler superimposed on the directional line drawn on the tablet after sighting the kipregel with a piece of paper with a sharp needle or compass needle.
На чертеже изображена предлагаема линейка.The drawing shows the proposed line.
Описываема линейка имеет существенное преимущество перед обычной масштабной линейкой, кипрегелем и циркулем, используемыми дл той же цели, так как применение ее значительно упрощает и ускор ет процесс отложени рассто ний при мензульной съемке.The described ruler has a significant advantage over a conventional large-scale ruler, a beater and a compass used for the same purpose, since its use greatly simplifies and speeds up the process of deposition of distances during transient photography.
Предмет изобретени Subject invention
