摘要： A method and arrangement for achieving a thorough degassing of developed diazo copy materal to eliminate the ammonia vapors permeating the developed diazo copy material as a result of the development process. The developed copy is moved from a development chamber containing the developing vapors into a degassing chamber, where the developed copy material is passed over a heated surface in intimate contact therewith to drive out the ammonia from the copy material. The ammonia vapors are carried away by a suction pump or fan to an external ammonia absorbing canister. In a first version, the heated contact surface is provided by a heated tube about which the developed print is drawn after passing off a developer-drive cylinder. In a second version, the developer-drive cylinder moves the developed copy material past a longitudinal seal engaging the drive cylinder, with the region on one side of the seal comprising a heated development chamber, while the region on the other side of the seal is subjected to a suction to evacuate the ammonia vapors. A heated, trough-shaped steel metal guide is positioned to receive and guide the developed copy material out of the machine to augment the degassing effect provided by contact with the heated developer-drive cylinder in the region subjected to suction.
摘要翻译：一种用于实现开发的重氮复合物的彻底脱气以消除由于显影过程渗透开发的重氮复制材料的氨蒸气的方法和装置。显影的副本从包含显影蒸气的显影室移动到脱气室中，其中显影的复印材料通过加热的表面与其紧密接触以从复印材料中排出氨。氨蒸汽被抽吸泵或风扇带走到外部的氨吸收罐。在第一版本中，加热的接触表面由加热的管道提供，在显影剂驱动的圆柱体上通过加热的管子将显影的印刷物拉出。在第二版本中，显影剂驱动筒将显影的复印材料移动通过与驱动圆筒接合的纵向密封件，密封件的一侧上的区域包括加热的显影室，而密封件另一侧的区域是进行抽吸以排空氨蒸汽。定位了加热的槽状钢金属引导件，以将显影的复制材料接收并引导出机器，以增强通过与经受抽吸的区域中的被加热的显影剂驱动圆筒接触而提供的脱气效果。
