Patent FR-2015810-A1 (FR)
Title: Ion exchanger treatment process
IPC: B01J47/10
Filed: 1969-08-14
Abstract: Ion exchangers are usually charged, washed in the opposite direction, purified and regenerated in the same apparatus. Nevertheless it is often advantageous, and even necessary, to separate the charging or filling operation from the purification and regeneration processes; in this case the ion exchanger is transferred from the service apparatus into a different recipient provided for regeneration, purification and washing in the reverse direction. The resin is transferred to the regeneration recipient, in the absence of pressure, and back again by using a liquid with a density higher than that of the exchanger resin, as the transfer medium; any such liquid may be used provided that it does not produce an undesirable reaction with the resinous matter. The process is used where the exchange resin is employed for treating a liquid which itself has a density higher than that of the resin, for example, in the decolouring of glycerol, glycol, gelatines and pectins and particularly in the treatment of sugar solution.

IPC: C08B37/10
Filed: 1973-04-13
Abstract: Single-metal salts of heparin with metals other than Na or mixed heparin salts are prepd. by contacting a suitable single-metal salt (esp.

Title: Hydraulic feed unit for pilger tube rolling mill - uses concentric air and oil cylinders for higher speed
IPC: B21B21/04
Filed: 1973-12-13
Abstract: The device is for the mfr. of seamless tubes and is mounted on a pilger mill, using a hydraulic cylinder to move the feed slide forward at a uniform velocity, thus pushing the tube-blank into the gap between the rolls. A compressed-air cylinder with a reciprocating piston is used, the shaft of the piston functioning as a second, differential piston in a smaller coaxial cylinder fed with hydraulic fluid and used for breaking the stroke; on the end of the shaft is a gear and a toothed rack which are used to turn the tube-blank through 90 degrees, i.e. to eliminate the flash on the tube. The higher reciprocating speed of this device means that, for a given roll speed, more tubes can be produced.
