Patent DE-3929985-A1 (DE)
Inventor: BEHR ARNO DR
IPC: C07C303/20
Filed: 1989-09-08
Abstract: The invention describes a process for producing short-chain alkane sulphonic acids and/or their salts by the addition of hydrogen sulphite to olefines in the presence of a radical starter. The novel process is characterized in that, to obtain largely sulphate and chloride-free alkane sulphonic acids, the corresponding olefine component is brought together with the aqueous hydrogen sulphite solution in at least stoichiometric quantities in the neutral to alkaline region, the closed reaction system is caused to transform under natural pressure at increasing temperature and the alkane sulphonic acid salts produced are converted, if desired, into free acids.

Patent DE-4026414-A1 (DE)
Inventor: LISSACK WILFRIED
IPC: F27B7/20
Filed: 1990-08-21
Abstract: In the process for reducing noxious compounds in the exhaust gases of a burner-fired smelting furnace, the material to be smelted is introduced into the furnace and supplied there with heat from a firing burner. For this purpose it is proposed that oxygen-rich gas is fed to the gas mixture flowing in the furnace, said gas being injected in such a way that the momentum of the gases from the firing burner and the momentum of the oxygen-rich gas supplied are oriented in parallel but not in the same direction. This produces gas turbulences in which the combustible pollutants are burnt and their discharge consequently prevented in the smelting furnace. <IMAGE>

ADVANTAGE - The machine rationalises the process. Minimises equipment costs and ensures that the finished frames are released rapidly.
Patent DE-4030620-A1 (DE)
Inventor: KERNER HORST
IPC: H03M7/00
Filed: 1990-09-27
Abstract: This method involves multiple formation of differences, these differences being coded in such a manner that those with a higher probability of occurrence are allocated shorter code words than those having a lower probability of occurrence. The number of differences formed is selected in such a manner that the coding of the differences results in a minimum of the mean code word length. In the digital processing of the signal values, this results in a reduction in the storage space required or in the transmission time. The invention is used in recording measuring instruments, particularly for network supervision. <IMAGE>

Inventor: SIMON ANDREA
IPC: A23L27/10
Filed: 1990-10-25
Abstract: A process for the production of highly concentrated fruit flavours from condensed fruit vapours is described,   a) the fruit flavours in the fruit vapours being concentrated up to a content of 0.05 to 1% by weight by methods known per se, b) the concentrate from step a) being subjected to an extraction with compressed carbon dioxide at 60 to 180 bar and 10 to 50 DEG C and also c) following reduction in pressure of the carbon dioxide and, if required, after addition of water, separating off the flavour-rich oily phase from the aqueous phase low in flavours.   In this manner, from very low concentration fruit vapour concentrates, a highly concentrated fruit flavour can be produced having a relatively low water or ethanol content and a high storage stability and good sensory properties.

Title: Detecting mismatch on feed line between radio transmitter and aerial - using directional couplers and generating AC voltage corresp. to waves propagated in both directions
Inventor: WEBER KLAUS DIPL ING
IPC: G01R27/06
Filed: 1990-11-30
Abstract: The mismatch is determined from waves propagated in both directions on the feed line, using a directional coupler (RIC) and a following evaluation. The directional coupler generates AC voltages, corresp. to the waves propagated over the feed line (SP) in both directions. After rectifying and RF filtering, measuring voltages are generated from the AC voltages, possibly using additional processing. One measuring voltage is weighted in a weighting circuit (GS) with a value, corresp. to the permitted mismatch threshold value. It is then supplied to a comparator (KO) input. The comparator generates an output signal when the weighted measuring voltage is smaller than the other one (non-weighted). ADVANTAGE - Rapid mismatch detection enabling transmitter switch-off within microseconds.

Title: Low friction shaft sealing ring - is elastomer with thin lips acting against revolving and stationary members respectively so as to provide seal whether shaft turns or not
Inventor: MUELLER HEINZ KONRAD PROF DR I
IPC: F16J15/32
Filed: 1990-12-04
Abstract: Shaft seal excludes liquids or gases at the point where the shaft passes through a housing. Seal is an elastic heat-resistant and wear-resistant material and can turn freely about the round surface of a feature fixed to the shaft and also about a stationary round body which is fixed to the housing. Parts of the sealing ring in contact with those surfaces have thin sealing lips pressed against the faces concerned and deformed correspondingly by their fit between the faces. ADVANTAGE - Friction against the sealed surfaces is less than normal even if lubrication is imperfect, or if the shaft runs dry or at high speed. Resultant temp. rises are therefore corresp. lower. Prod. and fitting of the seal are simple. Seal is unaffected deviations from the round. When the seal is being fitted on it is not liable to be damaged. (Dwg.1/2)
