Title: Recovery of hydrogen sulphide and ammonia from aq - solns
Inventor: JOSEPH KLETT ROBERT
IPC: C01B17/16
Filed: 1969-09-25
Abstract: Recovery of hydrogen sulphide and ammonia from aq solns. G6A. Which may also contain light hydrocarbons under high pressures, by reducing the pressure on the system and stripping off the H2S from the soln., light hydrocarbons to remove in a distillation column, stripping off the ammonia in a second distillation of (cf. 25246R as DT 1948428) from the aq. product at the bottom of the first column, then partially condensing the ammonia-rich gases at the top of the column whereby an ammonia-rich gas and condensate are obtained. Some of the ammonia-rich condensate is combined with the untreated aq. soln. (process I), some of which may contain light hydrocarbons, and which are removed in gaseous form in a degasser by lowering the pressure on the combined aq. soln. (process II). This combined aq. soln. is then led into the first distillation column, (process III). From 5 minutes to 24 hrs. (pref. is not 1hr, esp. pref. 3-24 hrs) are allowed to pass between process II and process III.

Title: Perfluoroalkyl sulphonylchlorides prepnfrom -
Inventor: DR STACH HANS DIPL-CHEM
IPC: C07C309/80
Filed: 1970-03-19
Abstract: Sulphonylchlorides of formula: Rf-(CH2)n-SO2Cl (in which Rf is 4-10C perfluoroalkyl and n is 2-4) are produced by mixing thiols of formula Rf-(CH2)n-SH with Cl2 at 0-15 degrees C in a satd. aq. suspension.

The sulphonylchlorides may be used as acylating agents, giving products with good oleophobic properties. The thiols are used to form corrosion resistant coatings on metals and to give oleophobic and hydrophobic properties to fibrous material. The isothiuronium salts are biocides and intermediates for the thiols. The thiols and isothiuronium salts are new cpds. when n = 2.

Title: Pipeline dirt collector with indicator - showing pressure difference across filter caused by collected dirt
Inventor: SEULEN MICHAEL G
IPC: B01D35/02
Filed: 1973-02-27
Abstract: A dirt collector for incorporation into a pipeline for liquids or gases contains a sieve; the differential pressure in the fluid across this sieve causes movement of a component which is biased against the differential pressure by a spring; the movement of the component under differential pressure is transmitted to a transmitter device which regulates a measuring or switching device, situated outside the flow path and chamber. As an alternative to a helical biasing spring, a metal bellows may be used. This arrangement gives a sensitive measurement of the pressure difference and therefore of the degre of clogging fo the filter.

Title: Wedge groove prodn semiconductor surfaces - by high-energy particle beam atomizing the material
Inventor: KRIMMEL EBERHARD DR RER NAT
IPC: B23K26/362
Filed: 1974-04-02
Abstract: Wedge-shaped grooves are produced on the surface of semiconductor devices, to control the breakdown voltage of thyristors, by directing a beam of atomic and/or molecular, electrically charged and/or neutral particles. The energy contained in the beam removes the material on the surface by atomization at the required angle of incidence which can be changed during the operation. This holds small angles (1 degree) of inclination more accurately than etching. It avoids the structural lattice disturbances introduced by mechanical stresses caused by grinding operations. It does not cause high temp. at the target which arises during electron beam bombardment and alters the properties of the semiconductor.
