Title: Electrodeposited coloured cobalt-chromium complex coating - esp. for stainless steels and non-ferrous metals
IPC: C25D9/08
Filed: 1981-10-07
Abstract: Coloured coating having excellent mechanical properties and corrosion resistance, esp. for stainless steels and non-ferrous metals, consists of a combination of a Co(III) complex and a Cr(III) complex. The Co(III) complex is pref. cobalt hexammine trichloride, Co(NH3)6Cl3, and the Cr(III) complex pref. has the formula (CrX)6Cl3 where X is one or more of H2O, NH3 and CN- (esp. chromium hexammine trichloride, Cr(NH3)6Cl3), the combined complex pref. having the formula ((NH3)5Co(III) - H2O-Cr(II) (H2O)5)4+ The chemically formed combined complex can be electrodeposited to give hard, crack-free coatings of colour varying from black to blue and violet-blue depending on deposition bath conditions. The combined complex is pref. electro-deposited by passing current between a lead anode and a cathode of the metal to be coated, in an ammoniacal soln. of CoCl2 and CrCl2 in the presence of activated carbon catalyst. Co(NH3)6Cl3 is formed in situ in the soln. by the presence of NH4Cl, NH3 and H2O2. Cr(NH3)6Cl3 is simultaneously formed in the presence of NH4Cl and NH3. The combined complex ((NH3)5CoIII-H2O-CrIII(H2O)5)4+ then forms by substitution of H2O in the newly formed Cr(III) complex. The resulting coating is black. By varying the concn. of the various ions in the soln., the NH3 in the Cr(III) complex can be replaced by H2O to modify the colour of the coating. By reducing the amt. of NH3 and adding excess water, in the presence of CN-, a violet-blue complex of formula CrCl2(H2O)4Cl.2H2O is formed instead of Cr(NH3)6Cl3. By varying the concns. of water, NH3 and CN-, a violet-blue complex of formula Co(CN)5H2O may be formed.

Title: Systeme de conference pour telephonie
Inventor: MIL JOB FRANCISCUS PETRUS VAN
IPC: H04M3/56
Filed: 1981-11-25
Abstract: L'invention concerne un système de conférence permettant de réaliser simultanément un échange d'information entre plusieurs participants E0, E1, ... EK. Dans les systèmes de conférence connus, la somme algébrique des signaux d'information des autres participants est fournie à chaque participant avec un rapport d'amplitude prédéterminé. Le signal "propre" n'est pas renvoyé en vue d'éviter des problèmes de stabilité. Un inconvénient de cette manière de procéder est que l'affaiblissement que subissent les signaux d'information est relativement important. Dans le système conforme à l'invention, on obtient un faible affaiblissement, tout en conservant une stabilité absolue, en renvoyant à chaque participant, son propre signal d'information avec un rapport d'amplitude prédéterminé. Application : système de conférence. (CF DESSIN DANS BOPI)
