    • In a ring communication system comprising selectively connectable data stations, each station has connecting circuitry including a phase-locked loop arrangement (111) which is frozen at its current frequency and phase in response to a signal interruption caused by a station insertion or removal operation. Control logic (113) generates a freeze control signal in dependence of the signal energy status on input lines (75). This control signal activates gates (149, 151) and switches (155, 157) to interrupt change control signals of the phase-locked loop circuitry and to keep an oscillator control voltage at a given value. The control logic also provides an auxiliary data signal during the freeze interval which is applied to the ring to keep stations downstream in synchronism. By this method and arrangement, undesired reactions and excursions of the phase-locked loop circuitry in response to a signal energy outage are prevented, and synchronization can be rapidly regained after station insertion or removal.
    • 在包括可选择地连接的数据站的环形通信系统中,每个站具有连接电路,该连接电路包括响应于由站插入或移除操作引起的信号中断而冻结在其当前频率和相位的锁相环装置(111)。 控制逻辑(113)根据输入线(75)上的信号能量状态产生冻结控制信号。 该控制信号激活门(149,151)和开关(155,157)以中断锁相环电路的改变控制信号,并将振荡器控制电压保持在给定值。 控制逻辑还在冻结间隔期间提供辅助数据信号,该信号被施加到环上,以使站下游同步。 通过该方法和布置,防止响应于信号能量中断的锁相环电路的不期望的反应和偏移,并且可以在站插入或移除之后快速恢复同步。

    • A bottom unit for the combustion chamber of a liquid-fueled rocket including a bottom plate held on a swivel bearing and having circumferentially distributed openings for the injection of the two fuel components as well as two separate groups of supply passages which are connected to these fuel injection openings. The swivel bearing consists of a rigid thrust plate and a rigid hanger plate which are held and joined together by an internally situated, first annular body of rubber elastic material and by a second annular body of rubber elastic material surrounding the first at a radial distance therefrom. The one group of supply passages is formed by the cavity surrounded by tthe first annular body and the other group of supply passages by the annular space between the first and the second annular body.

    • A picture frame has a plastic rear wall wherein a bearing member is mounted so as to be pivotable about an axis orthogonal to the rear wall between a first and a second end position spaced by 90.degree.. A prop is hinged to the bearing member so as to be unfoldable from a recess of the rear wall into a first spread-apart position when the bearing member assumes the first end position and into a second spread-apart position when the bearing member is in its other end position. In either spread-apart position, the prop defines a different angle with the rear wall, said angles being determined by stops on the rear wall cooperating with stops on the prop.
