Abstract: A braking system for electric step motors that operate in conjunction with a light assembly, including a moving head for pan or tilt thereof or for moving internal optical components. The step motors are connected to driving means to reduce movement speed of the moving head during power down and are connected through switches with a first operating position to connect the driving means to the step motors, and with a second power down position to establish a current path through a motor winding. Movements after power down take place very slowly and without generating noise for use in a theatre where the lamp may be switched off because a fuse burn out, and so cease operation without making disturbing noise. In a controlled power down, noise is reduced when several lamp fixtures placed side by side at the same time move to a stop position.

Abstract translation: 一种用于电动步进电动机的制动系统，其与轻组件一起操作，包括用于摇动或倾斜的移动头或用于移动内部光学部件。 步进电机连接到驱动装置，以减少停电期间移动头的移动速度，并且通过具有第一操作位置的开关连接以将驱动装置连接到步进电动机，并且具有第二停电位置以建立电流 通过电机绕组的路径。 断电后的运动发生得非常缓慢，不会产生噪音，因为保险丝烧坏灯泡可能会关闭灯泡，因此在不影响噪音的情况下停止工作。 在受到控制的电源关闭中，当同时并排放置的几个灯具固定在停止位置时，会降低噪音。

Abstract: A system for storage and dosing of ammonia, including a solid ammonia storage material capable of binding and releasing ammonia reversibly by adsorption/absorption. The system is able to release ammonia gradually according to a demand that can vary over time with intermediate periods of no ammonia demand. A main storage unit and a start-up storage unit are provided. The storage units hold ammonia storage material. At least one one-way valve is provided via which the one main storage unit is in communication with the start-up storage unit. The one-way valve prevents any back-flow of ammonia from the start-up storage unit to the main storage unit. Heating devices are arranged to heat the main storage unit and the start-up storage unit separately to generate gaseous ammonia by thermal desorption from the solid storage material. A controller controls the heating power of the main storage unit and the start-up storage unit, thereby enabling ammonia release from at least one of the start-up and/or the main storage unit. A dosing valve controls ammonia flow from the storage units according to a demand.
