Description

В основном авт. св. № 64717 описан волос ной гигрометр с указательной стрелкой, у которого стрелка подвешена на двух закрученных в противоположные стороны бифил рах-нетл х.Basically auth. St. No. 64717 describes a hair hygrometer with a pointing arrow, in which the arrow is suspended on two opposite-facing bifilates.

Отличительна  особенность предлагаемого указательного устройства состоит в том, что, с целью увеличени  чувствительности, стрелка св зана как с подвижным, так и с неподвижным основанием прп иомощи двух двухиетельных подвесов, выполненных из нитей различного сечени .A distinctive feature of the proposed pointing device is that, in order to increase the sensitivity, the arrow is connected with both a moving and a fixed base of the aid of two two-wire suspensions made of threads of different cross sections.

На чертеже схематически изображ.ено указательное устройство.The drawing schematically depicts a pointing device.

Неподвижный элемент 1 соединен с подвижным элементом 2 двум  раст нутыми двухпетельными подвесами.The fixed member 1 is connected to the movable member 2 by two stretched two-loop hangers.

Каждый подвес состоит из двух петель 4 и 5, изготовленных из проволок различного поперечного сечени  и закрученных в противоположные стороны. Середины обоих подвесов соединены вместе. К месту соединени  подвесов прикреплена стрелка 3.Each suspension consists of two loops 4 and 5, made of wires of different cross section and twisted in opposite directions. The middle of both hangers are connected together. An arrow 3 is attached to the junction of the suspensions.

В начальном положении угол закручивани  петли 4 из толстой нити больший, чем петли 5 из тонкой нити.In the initial position, the twist angle of the loop 4 of the thick thread is larger than the loop 5 of the thin thread.

При увеличении продольного нат жени  обе петли удлин ютс . Однако у петли 4, нити которой толнхе, удлинение св зано с большими усили ми, чем у петли 5, нити которой тоньше. Нри раст жении перва  петл  будет раскручиватьс , а втора  закручиватьс , поворачива  при этом стрелку 3. Угол поворота стрелки характеризует величину продольной деформации.As the longitudinal tension increases, both loops lengthen. However, with loop 4, the filaments of which are under the waves, the elongation is associated with greater forces than those of loop 5, whose filaments are thinner. If the first loop is stretched, it will unwind and the second will twist, turning the arrow 3. The angle of rotation of the arrow characterizes the magnitude of the longitudinal strain.

Форма выполнени  устройства ио авт. св. № 64717, отличающа с  тем, что, с целью увеличени  чувствительности, стрелка св зана как с подвижной пластинкой, так и с неподвижиым основаниемThe form of the device and its author. St. No. 64717, characterized in that, in order to increase the sensitivity, the arrow is associated with both the movable plate and the non-movable base.
