| titleOfInvention | METHOD AND DEVICE FOR SUBDIVISING A GLASS TUBE FILLED WITH RADIOACTIVE GAS |
| abstract | A glass tube containing a radioactive gas and coated internally with a phosphor is cut into individual sealed segments. A laser beam 11, 13, 17, 14, 16, 21 is directed onto two large lateral surfaces of the tube 9, in a chamber 8 maintained at a pressure greater than the pressure of the gas in the tube. By a backward and forward sweep of the laser beams 17 and 21, obtained by relatively moving the tube and the laser beams, the tube is heated and softened along a cutting line until it divides to form ends on the side. side of that cut line, and that it contracts, sealing the split ends. Application to the manufacture of miniature self-luminescent sources. |
