Title: Process for removing hydrogen sulphide from industrial gases
Inventor: KLEEBERG ULRICH DR RER NAT
IPC: B01D53/52
Filed: 1981-02-05
Abstract: The invention relates to a process for removing the hydrogen sulphide from industrial gases having a low oxygen content, in particular having an oxygen content less than 0.1%. The hydrogen sulphide-containing gas is introduced into a scrubbing tower and is there scrubbed by a Stretford scrubbing liquid containing one or more anthraquinone acids and/or salts thereof. The clean gas is conducted out of the scrubbing tower, the Stretford scrubbing liquid is taken off from a scrubbing tower delay tank and fed to an oxidiser. Air is blown into the oxidiser and sulphur is withdrawn from the oxidiser by flotation and fed to sulphur processing, while the Stretford scrubbing liquid is pumped back to the scrubbing tower. In the Stretford scrubbing liquid, thiosulphate is formed during the scrubbing process. In order that interfering losses of the anthraquinone compounds used do not occur and further that thiosulphate destruction is not necessary in the waste water treatment, hydrogen sulphide ions are introduced into the oxidiser from the scrubbing tower. As a result, a thiosulphate level of over 15 grams per litre, preferably in the range from 20 to 200 grams per litre, is maintained in the Stretford scrubbing liquid. Surprisingly, interfering losses of the anthraquinone salt used or of the anthraquinone salts used are avoided in this manner.

Patent DE-3105399-A1 (DE)
Title: Process for the preparation of carboxylic acid esters
Inventor: SCHLEPPINGHOFF BERNHARD DIPL C
IPC: C07C67/04
Filed: 1981-02-14
Abstract: The present invention relates to a process for the preparation of carboxylic acid esters by reaction of olefins with aliphatic or aromatic carboxylic acids. The reaction according to the invention is performed on acidic ion exchangers whose acid groups are partially neutralised by cations. By this means, the undesired formation of oligomers or polymers is largely suppressed. Depending on the sensitivity to polymerisation of the olefins to be reacted, 1 to 50% of all acid groups present are neutralised when using olefins and/or carboxylic acids which are only slightly sensitive to polymerisation. When using olefins and/or carboxylic acids which are highly sensitive to polymerisation, about 35 to 85% of all the acid groups of the ion exchanger present are neutralized. Monovalent cations are preferably employed for neutralisation. In addition to metal cations, the hydronium ion, the ammonium ion or various alkylammonium ions can be employed. The process according to the invention can be carried out at a temperature of about 0 to 140 DEG C and a pressure of about 0.5 to 100 bar.

IPC: A61C5/77
Filed: 1981-07-21
Abstract: The invention relates to a method of adapting dentures to the dental stumps and the gingiva above these by means of correspondingly prepared impressions and casts of the areas of the mouth. The replica of the area of the mouth takes the form of a so-called master model. In this model the dental stumps are arranged so as to be removable. The gingiva located above each particular dental stump is ground away in the master model in order to achieve a better transition between denture and neck of the dental stump. In order to achieve an additional, exact adaptation of the denture to the gingiva, the gingiva is reproduced in the master model in the form of artificial gums. These artificial gums are adapted to resemble the natural gingival conditions as closely as possible, including the softness thereof. These artificial gums comprise a free-flowing, curable, ductile material and are releasably connected to the master model. The artificial gums are expediently made of two parts, so that the rear gingival region and the front gingival region can be inserted separately.
