    • Novel dyestuffs containing amino or imino groups and their preparation are provided.These dyestuffs have the general formula ##STR1## wherein R is --N(R.sub.3)CH.sub.2 --Z or --N.dbd.CH--Z, X is N or CR.sub.6 where R.sub.6 is a hydrogen atom or an optionally substituted alkyl or aryl group, Y is S.sup..sym., O.sup..sym., N or N.sup..sym. R.sub.7 where R.sub.7 is a hydrogen atom or an optionally substituted alkyl or aryl group, R.sub.1, R.sub.1 and R.sub.2 each represent a hydrogen atom or an alkyl group having from 1 to 4 carbon atoms, or R.sub.1 and R.sub.2 together with the nitrogen atom complete a heterocyclic ring, or one of R.sub.1 and R.sub.2 can be hydrogen and the other of R.sub.1 and R.sub.2 can be aryl, Z is a group which comprises both an activating group which contains at least one double bond system and also a ballasting group and R.sub.4 and R.sub.5 each represent optional substituents or form an annelated benzene ring. The new dyestuffs are useful in the photographic field especially in the photographic dye diffusion transfer process for the production of photographic images.
    • 提供了含氨基或亚氨基的新型染料及其制备方法。 这些染料具有通式,其中R是-N(R3)CH2-Z或-N = CH-Z,X是N或CR6,其中R6是氢原子或任选取代的烷基或芳基,Y是 S(+),O(+),N或N(+)R7,其中R7是氢原子或任选取代的烷基或芳基,R 1,R 1和R 2各自表示氢原子或烷基, 4个碳原子,或者R1和R2与氮原子一起完成一个杂环,或者R 1和R 2中的一个可以是氢,R 1和R 2中的另一个可以是芳基,Z是包含活性基团的基团, 至少一个双键体系和还有一个压载基团,R4和R5各自代表任选的取代基或形成一个环状的苯环。 新的染料在照相领域中是有用的,特别是在用于制作摄影图像的照相染料扩散转移过程中。

    • According to the present disclosure, a digital vehicle microphone system for recording and playback of announcements pertaining to vehicle stops and route information is provided for use over public address systems installed on public transportation vehicles. The system includes a microphone apparatus for digitally pre-recording the announcements. The microphone apparatus includes a microphone, a mute switch, a radio mode switch, a record switch and a record indicator. The system also includes a control circuit for recording and storing at least two separate announcements onto memory storage devices. The control circuit further includes a delayed playback feature for delayed playback of the announcements through the vehicle's public address system. The microphone apparatus further includes a “hands free” microphone including hand and foot actuated recording switches. The hand actuated record switch is used to record the vehicle's route information and the foot actuated record switch is used to record the vehicle's upcoming stop announcements. A method of operating a vehicle public address system is also disclosed.
    • 根据本公开,提供了用于记录和回放关于车辆停靠和路线信息的通知的数字车载麦克风系统,用于在公共交通工具上安装的公共广播系统。 该系统包括用于数字预录制公告的麦克风装置。 麦克风装置包括麦克风,静音开关,无线电模式开关,记录开关和记录指示器。 该系统还包括用于在存储器存储设备上记录和存储至少两个单独通告的控制电路。 控制电路还包括用于通过车辆公共广播系统延迟播放通知的延迟播放特征。 麦克风装置还包括一个“免提”麦克风,包括手和脚启动记录开关。 手动记录开关用于记录车辆的路线信息,并且脚部启动记录开关用于记录车辆即将到来的停止通知。 还公开了一种操作车辆公共广播系统的方法。
