Description

Предлагаемое приспособление дл  настройки радиоприемников имеет целью дать возможность использовать в большей степени, чем обычно вариометр приемника путем переключени  частей его катущки с последовательного соединени  на параллельное .The proposed tool for tuning radio receivers is intended to enable the use of a more variably than usual receiver variometer by switching parts of its coil from a series connection to a parallel one.

На чертеже изображена схема соединени  вариометра и дискового переключател .The drawing shows a diagram of the connection of the variometer and the dial.

Приспособление дл  настройки радиоприемников состоит из изолирующего диска 3 с укрепленными на нем, изолированными друг от друга полудисками 1, 2 разного диаметра , вариометра с катушками а и b и щеток 4, 5. Полудиск 1 соединен с концом катушки Ь, а полудиск 2 с средней точкой катушек а к Ь вариометра .The device for tuning the radio receivers consists of an isolating disk 3 with reinforced half disks 1, 2 of different diameter, a variometer with coils a and b, and brushes 4, 5 fixed to it. The half disk 1 is connected to the end of coil b, and the half disk 2 from middle point coils a to b of the variometer.

В положении, когда щетка 4, соединенна  с началом катушки а вариометра и с антенной, касаетс  кра  полудиска 1, а щетка 5, соединенна  с землей-полудиска 2, катушки а и b вариометра соединены параллельно и остаютс  в таком соединении лри повороте оси б от 5 до 180°. При дальнейшем повороте оси полудиск 1 сойдет со щетки 4 и перейдет на щетку 5, а полудиск 2, будучи меньшего размера, сойд  са щетки 5, не коснетс  щетки 4 и катушки окажутс  соединенными последовательно , остава сь в таком соединении до перехода в начальное положение.In the position where the brush 4 is connected to the beginning of the coil a of the variometer and the antenna, touches the edge of the half disk 1, and the brush 5 is connected to the half-disk 2, coils a and b of the variometer are connected in parallel and remain in this connection 5 to 180 °. When the axis is further rotated, the half-disk 1 will come off the brush 4 and will go to the brush 5, and the half-disk 2, being smaller, will descend on the brush 5, will not touch the brush 4 and the coils will be connected in series, remaining in such a connection until it moves to the initial position.

Предмет патента.The subject of the patent.

Приспособление дл  настройки радиоприемников, характеризующеес  тем, что насаженный на ось б вариометра дисковый переключатель снабжен двум  изолированными друг от друга полудисками 1, 2 разного радиуса, закрепленными на нзолкрующем диске 3, из каковых полуди сков: полудиск 2 соединен с средней точкой катушки а, Ь вариометра, полудиск 1 с концом одной Л из катушек вариометра, при чем щетки 4, 5 переключател  соединены-одна с землей, а друга  с антенной и на чалом одной а из катушек вариометра .A device for tuning radio receivers, characterized in that the rotary switch mounted on the b axis of the variometer is equipped with two isolated half disks 1, 2 of different radius fixed on the clutch disk 3, of which half the clock: the half disk 2 is connected to the midpoint of coil a, b the variometer, half disk 1 with the end of one L of the coils of the variometer, the brushes 4, 5 of the switch are connected — one with the ground, and the other with the antenna and at the beginning of one of the coils of the variometer.
