Their initial direction is at right angles to the lines of force of the magnetic field, and also at right angles to the direction in which the mass moves ; therefore, in the shuttle armature, they travel lengthways along the iron core, completing their circuit in a more or less circular path in the iron (whence they gain the name of
Strona 81 - There is a strong consensus of opinion among persons engaged both in science and in industry that a special need exists at the present time for new machinery and for additional State assistance in order to promote and organize scientific research with a view especially to its application to trade and industry.
Strona 131 - I may here also confess that as a little boy I was much given to inventing deliberate falsehoods, and this was always done for the sake of causing excitement.
