摘要:
For initial threading of a coil of metal through a rolling mill the settings of the mill are modified, in accordance with calculated and measured data, to minimize the amount of distortion on the nose of the coil of metal. The settings of the mill are then returned to a nominal schedule for rolling the rest of the coil.

A synthetic graphics generating system, using a C.R.T. scanned in a T.V. type raster. The video signal for each linescan is calculated digitally in real time, either during the linescan flyback periods, or during execution of the preceding linescan. The described system is used to generate a number of vectors, the calculations for which are performed on a time-shared basis by common circuitry. To prevent a stepped appearance, progressive increase and decrease in brightness is used, preferably using three discrete brightness levels.
摘要:
A coupling device for use between a digital computer supplying incremental control signals and a plurality of analog stations which are respectively controlled by analog control signals, said coupling device comprising, for each station, two photocouplings for receiving pulses representing the increasing variations and decreasing variations respectively, of said incremental control signals, and an integrator for receiving the outputs of said photocouplings to supply the corresponding analog quantities to the analog stations, the photocouplings being adapted to ensure a galvanic isolation between the analog stations themselves on the one hand and the analog stations in relation to the coupling on the other hand, while allowing a very short coupling occupation time.
