DE 3224644 A1 5 Jan 1984,12 pp. (German). (Germany). 7721-01-9 and 12069-94-2 which are cas registry numbers are also used here. CODEN: GWXXBX. CLASS: IC: H01S003-097; C01B031-30. APPLICATION: DE 82-3224644 1 Jul 1982. DOCUMENT TYPE: Patent CA Section: 73 (Optical, Electron, and Mass Spectroscopy and Other Related Properties) A shell-type cathode for gas lasers, esp. for CO2 lasers, consists of a 3-layer material contg. nonstoichiometric Group VB carbides MCx of the compn. x = 0.74-0.95 and x = 0.92-0.96 in the outter and inner layers, resp. The cathodes are fabricated by heating graphite to 2300-2500° for 5-8 h in an Ar atm. contg. MCl5 (M = Nb, Ta). Alternatively, annealing of semifabricated Nb or Ta products in a powd. graphite load in Ar atm. at 2000-2200° for 5-10 h can be used. Due to a high resistance of the carbides to the ion-beam sputtering, the cathode is characterized by a substantially longer lifetime compared to metal cathodes. .

APPLICATION: US 82-415201 7 Sep 1982. DOCUMENT TYPE: Patent CA Section: 35 (Chemistry of Synthetic High Polymers) Group VB metal chloride catalysts show high selectivity in oligomerizing 1-alkenes to products useful as lubricants. Thus, stirring 1.5 g TaCl5, 18.0 g 1-decene, and 75 mL heptane for 2.5 h at 149° gave an 84% conversion to a product contg. 55% C30-40 oligomers. .
