    • An encapsulated medium-voltage electrical load switching apparatus has four, three-position rotary switches, supported by pairs of opposing insulated half-shells, two-over-two in parallel alignment within a gas-filled sealed shut shell housing.The housing front and back have dome-shaped protrusions to maintain the seal against fluctuations in gas pressure. Bushings in the floor and ceiling of the housing, aligned with the switch face plane, provide gastight connections between the switches and external cables, enclosed fuses and transformer terminals. Switch control is provided by drives mounted on a plate at the front of the housing exterior which operate actuator arms that extend in a gastight way through the housing front and manipulate selector shafts that connect to set the switches into closed-circuited, open-circuited and grounded positions. Internal conductors establish connection from a cable through a fuse to a transformer terminal when the two upper switches and one of the lower switches are closed-circuited.The disclosed apparatus offers the advantages of low cost, compactness and freedom from maintenance.

    • An electrically controlled fuel metering system having an air flow rate meter device in the air intake tube and a subsequent linearizing circuit layout is proposed. The linearizing circuit layout functions in accordance with the point-slope method and is embodied as a voltage-to-current converter. A first exemplary embodiment of the linearizing circuit layout has transistors coupled with one another respectively at the base and collector sides, the emitters of which are connected with different potentials and are triggered on the base side. In a second exemplary embodiment, individual transistors or transistors which are combined into groups receive their trigger signal via separate amplifiers, while the collectors in turn are carried to a common output point and the emitters likewise have different signal levels. Because of its relatively simple design, the proposed embodiments are particularly well suited to the purposes of integration.
    • 一种电气控制燃料计量系统,其具有进气管中的空气流量计装置和随后的线性化电路布局。 线性化电路布局根据点斜率法进行功能化,并被实现为电压 - 电流转换器。 线性化电路布局的第一示例性实施例具有分别在基极和集电极侧彼此耦合的晶体管,其发射极与不同的电势连接并且在基极侧被触发。 在第二示例性实施例中,组合成组的各个晶体管或晶体管经由分离的放大器接收它们的触发信号,而集电器又被传送到公共输出点,并且发射器同样具有不同的信号电平。 由于其相对简单的设计,所提出的实施例特别适合于集成的目的。
