| THE STROBORAMA The latest invention for the immobilisation of movements of different kinds, i. e.{Mr Elliott - Chief Engineer} of machine parts, fluids gases, etc. and for the examination of such movements. No. 1. STROBORAMA A; 1000 candle power. Note on the Stroboscopic Method in general and the application of the “Stroborama”. The Stroboscopic method is a method of analysing periodical rapid movements, which consists of presenting to the eye objects under observation only when they are in the same point of space, and in the same phase of movement, while for the remainder of the time they are invisible. This gives the impression that they are motionless or moving very slowly, if the phase of observation is slightly varied. In fact the different images registered by the eye are connected to each other in much the same way as the pictures recorded by the cinematograph, provided that the images succeed each other sufficiently rapidly. It thus becomes possible by observing the motionless or slowly moving image, to realize phenomena, which are taking place in reality during the movement of the part under observation; such phenomena being normally quite invisible owing to the speed of the moving part. All these particularities of movement can be analysed and all kinds of troubles and irregularities may be observed such as vibrations, jumping, deformations, bending etc. impossible to detect otherwise. In every case the most precise measurements may be | ||
