    Abstract: In the ignition and starting phase of a high pressure combustion chamber device enables the flow velocity in the combustion pipe of the combustion chamber (21) to be reduced by the blocking air injected in counterflow through a slot nozzle in the narrowest cross section at the combustion chamber outlet (17) to such an extent that it is less than the flame propagation velocity. Owing to the fact that an adjustable throttle aperture (18) is fitted in the starting air line (16), during the starting process the pressure of the air jet issuing from the combustion chamber (21) is always less than the blocking air flow. As soon as a combustion chamber outlet temperature which can be associated with a stable state of operation in the combustion chamber (21) is measured on the temperature sensor (22), the drive (12) for the valve (11) is put into operation by means of a temperature-dependent switch-over device (23), which drive isolates the starting air line (16) and the blocking air line (15) from the air line ( 10) and connects this with the operating air line (20), and, because the valve (11) is designed with negative overlap, the air supply to the combustion chamber (21) is not interrupted.

    Abstract translation: 在高压燃烧室的点火和启动阶段，该装置使得能够通过在最狭窄截面中的狭缝喷嘴以逆流方式注入的阻塞空气来减少燃烧室（21）的燃烧管中的流速。 燃烧室出口（17）的温度达到低于火焰传播速度的程度。 由于在起动空气管路（16）中安装有可调节的节流孔（18），所以在启动过程中，从燃烧室（21）发出的空气流的压力总是小于阻塞气流。 一旦在温度传感器（22）上测量可与燃烧室（21）中的稳定运行状态相关联的燃烧室出口温度，则阀（11）的驱动器（12）投入运行 通过温度依赖的切换装置（23），该驱动将起动空气管路（16）和阻塞空气管线（15）与空气管路（10）隔离，并将其与工作空气管路（20 ），并且因为阀（11）被设计成具有负重叠，所以不会中断对燃烧室（21）的供气。

    Abstract: Communication unit comprising a housing (1) in which at least one transducer is placed, and on which a microphone arm (2) is suspended. The housing also has an ear hook (6) for fastening the communication unit to the head of a user. The microphone arm (2) is pivotally connected to the housing (1) by a hinge link (3,4,5) at an outer area of the housing, and so that the microphone arm (2) can be moved between a position in which it lies up against the housing (1), and a position in which it extends away from the housing. The microphone arm has a length, which in the main is less than or of the same order as the greatest extent of the housing, so that in the folded-in state the microphone arm does not project out over the circumference of the housing.
