摘要: Strip material is fed to a reduction rolling mill by a steering device in the form of a pinch roll stand comprising pinch rolls to which strip gripping forces are applied by hydraulic cylinder units located at the ends of the pinch rolls. A reduction mill is similarly provided with a pair of hydraulic cylinder units which are independently operable to vary the pressure applied by the reduction rolls across the strip. Sensors sense the position of the strip at a first location in advance of the pinch rolls and a second location in advance of the rolling mill. This output of sensors is fed to a controller which controls operation of both sets of hydraulic cylinder units to steer the strip.

摘要: Twin roll casting of metal strip (20) by rotation of parallel casting rolls (16) supplied with molten metal through distributor (19a) and delivery nozzle (19b). X-ray scanner (44) continuously scans the thickness of strip (20) to produce a signal which is a continuous measure of thickness variation along the strip due to eccentricities of the casting rolls (16). This signal controls operation of roll drive motors (53) to impose a pattern of speed variation on the rolls so as to reduce the amplitude of the thickness variations.

摘要: A cigarette vending machine that dispenses a single cigarette at a time. The cigarette vending machine includes a touchscreen that allows a user to select a particular brand of cigarettes. In addition, the vending machine includes a camera and an identification reader so that the user's age can be verified, and so that the user can be verified to be the same person as the identification holder.

摘要翻译: 通过经由分配器(19a)和输送喷嘴(19b)供给熔融金属的平行铸辊(16)的旋转来对金属条(20)进行双辊铸造。 X射线扫描器(44)连续地扫描条带(20)的厚度,以产生信号,该信号是由于铸辊(16)的偏心度而沿条带的厚度变化的连续测量值。 该信号控制辊驱动马达(53)的操作,以在辊上施加速度变化的图案,以便减小厚度变化的幅度。
