| Télégraphic Adress : Stroboroma-Paris RECHERCHES MÉCANIQUES & PHYSIQUES Société anonyme au capital de 100.000 francs 40, Rue de l'Echiquier - PARIS Téléphone : Provence 18-35 STROBORAMA, Type A (L. & A.{Mr Adams} SEGUIN Patents) Works on all alternating currents from 110 to 240 volts and from 40 to 60 periods. The STROBORAMA is an apparatus which permits the examination of all quick-moving mechanisms by giving them the appearance of immobility or of very slow motion. The STROBORAMA utilises the stroboscopic method which consists in lighting the mechanism to be examined by a succession of luminous flashes which are practically instantaneous and the frequency of which can be regulated, in such a way as to give the mechanism the appearance of being at a standstill or of revolving very slowly. The STROBORAMA is an apparatus giving great intensity of illumination permitting examination in full daylight under the normal conditions existing in the workshop. Its projector A of about 1.000 C. P. is contained in a case mounted on wheels and can easily be moved into a good position in order to illuminate the mechanism to be examined. The synchroniser B which is used to regulate the frequency of the flashes is provided with a Tachymeter C indicating this frequency.
