The new AA3000 series electric cylinders from Beckhoff are ideally suited as direct drives for linear motion applications with high process forces and speeds. ... composed of precise roller bearings, ...

MY last letter in NATURE of March 7 (p. 436) substantially contended that there must be a certain limit to the rate of translatory motion possible to meteoric masses, beyond which they would be ...

If, therefore, the Pauli principle is valid not only for the electrons of an atom but also for the translatory motion of gas molecules, with radius almost zero, ...
