Title: Process for the purification of industrial solutions of hafnium and zirconium salt
Inventor: DE CALMES ALAIN
IPC: C01G25/00
Filed: 1965-11-26
Abstract: Phosphorus and titanium-containing solutions of hafnium and/or zirconium nitrate, are purified by (a) eliminating a major part of the phosphorus as phosphates of Hf and/or Zr, e.g. by decanting the precipitate which forms on settling; (b) diluting the solution to 1.5N; (c) passing the solution through a cation exchange resin, to fix the Hf and/or Zr and the traces of phosphate and Ti; (d) eluting with 1.5 nitric acid to eliminate Ti; (e) eluting Hf and/or Zr with 1.5-3N sulphuric acid; (f) allowing the resulting solution to stand, and decanting to eliminate last traces of phosphorus as phosphates. In step (a), the P2O5: Hf and/or Zr oxide ratio is preferably reduced to 0.2-0.3%.  The cation exchange resin may be an aromatic hydrocarbon polymer containing sulphonic groups. In an example, the sulphuric elution solution was treated with gaseous ammonia to precipitate the oxides of Hf and Zr which were filtered, washed and calcined at 900 DEG  C.

Title: Improvements in or relating to textile machines, for example looms
Inventor: GEORGI DIETER
IPC: D03D39/16
Filed: 1966-11-24
Abstract: The invention relates to a loom or other machine having cutter mechanism for separating face-to-face pile fabrics, the mechanism comprising a knife, reciprocated by a rope and oscillating pulley drive.  One of. the pulleys drives a generator which supplies current to one winding of a relay; a second winding is supplied with current from a separate source controlled by a timing switch, so that the two magnetic fields normally cancel out and the relay remains unoperated. If the pulley mechanism fails, the current in the second winding operates the relay to stop the machine.  In order that the relay shall not be operated by the second winding as the generator is starting up, a third winding is fed by current which passes through it for a short period to charge a condenser.
