Title: Regeneration process for solid matter adsorption filter - burns steam-desorbed impurities raising more steam possibly for storage
Inventor: BIEWALD HORST
IPC: B01D53/02
Filed: 1978-11-03
Abstract: Combustible organic impurities which are adsorbed, e.g. in filters contg. active carbon are desorbed by steam in a process for the periodic regeneration of filters. Air is fed into the stream contg. the desorbed matter so that it can be burned. The exhaust gases from this combustion are used in heat exchangers for the generation of steam, and the steam is used for desorption. System cheapens and simplifies the desorption of active carbon filters in a gentle manner. The prodn. of an inert gas from oil or natural gas with the need to ensure the absence of O2 from the prod. is superceded. The process is patic. used when only small amts. of combustible impurities are present and large amts. of exhaust gases have to be handled.

Patent DE-2932881-A1 (DE)
Inventor: WILL PETER DR MED
IPC: A61F5/02
Filed: 1979-08-14
Abstract: A device for treating faulty positions and postures of the human torso by means of at least one lockable force storing mechanism inserted into strapping lying against the body and having a locking element so coupled with a strap mounting element displaceable relative to the casing of the storage mechanism and biased towards a starting position, of a tension strap transmitting postural changes of torso to the force storage mechanism that the strap mounting element in the period of time of the desired postural correction blocks the force storage mechanism when the tension strap is held substantially free of tension. At least one measuring strap or Bowden cable is connected to the strapping and to the force storage mechanism. This strap or Bowden cable upon the assumption of faulty posture of the torso releases the locking of the force storage mechanism whereby the tension strap is effectively tensed with intensified pull in the direction of the faulty posture and remains tense until, by a postural correction of the wearer acting against the spring tension of the force storage mechanism the locking element locks the strap mounting while the strap is again free of tension.
