    Abstract: A method of fabricating a plurality of buzzers from an initial stamping. The stamping is formed having a configuration defining the metal parts of four buzzers with individual circuit portions interconnected by webs. Respective plastic bases are molded to the circuit portions of each buzzer at respective positions on the stamping and the webs are then sheared to both separate the buzzers and enable the appropriate electrical circuits to be completed.

    Abstract: An electromagnetic vehicle turn signal flasher in which lamps are lighted and a bulb outage relay is energized through normally closed contacts on operation of the turn signal switch. The relay armature operates to energize a timing relay, which deenergizes itself and momentarily opens the normally closed contacts to deenergize the outage relay and extinguish the lamps. The contacts, on reclosing, relight the lamps and energize the outage relay to repeat the cycle. The outage relay armature either does not operate or releases before the closed contacts have opened, if a lamp has failed, to maintain the dashboard indicator lamp continuously lighted for signalling the lamp failure. To enable the operated outage relay armature to release on lamp failure, the armature is held a predetermined distance from the core so that as the resistance of the remaining energized lamp filaments increases, the outage relay current decreases sufficiently to cause armature release.

    Abstract translation: 一个电磁车辆转向信号闪光器,其中灯被点亮,并且在转向信号开关的操作时灯泡中断继电器通过常闭触点通电。 继电器电枢操作以对定时继电器​​通电,定时继电器​​自动断电并且暂时打开常闭触点以使中断继电器通电并熄灭灯。 触点重新闭合时,重新点亮灯泡,并为断电继电器通电以重复循环。 断电继电器电枢在闭合触点断开之前不起作用,如果灯泡出现故障,则维持仪表板指示灯持续点亮,以指示灯泡故障。 为了使操作的中断继电器电枢在灯管故障时释放,电枢保持与芯的预定距离,使得当剩余的通电灯丝的电阻增加时,停电继电器电流充分降低以引起电枢释放。
