Title: Magnetic pulse lap lding of coaxial metal tubes - with electric resistance preheating of joint area by pulsed current
Inventor: MININ VLADILEN FEDOROVITSCH
IPC: B23K20/06
Filed: 1975-09-11
Abstract: Two coaxial tubes are joined by lap welding, one tube being moved whereas the other is stationary. The joint area of the two tubes is preheated and the moving tube is then deformed but the pressure of a pulsed magnetic field so it is pressed onto the stationary tube to form a lap weld. The novelty is that the preheating operation is achieved by passing electric current radially between the two tubes and on the entire peripheries of the tubes, so the joint areas is heated by electrical resistance. Pulsed current may be used for preheating, and the lap welds pref. consist of Cu to Cu; steel to steel; Al to Al; Cu ot steel; Al to steel Ti to steel; Cu to Ti.

IPC: G21F9/20
Filed: 1975-11-14
Abstract: Decontaminating organic wastes (faeces and urine) contg. radioactive substances, esp. in hospitals, consits of immediately transferring the waste from the toilet into a closable vessel; the vessel is closed and all such vessels are then stored, each for the appropriate radio-active decay period. When the decay period has elapsed, the contents are discharged into the sewage system. The vessels and contents may be frozen for the period of radioactive decay. Bages may be used as vessels-with or without freezing-and decomposition-inhibitors may be added to the contents. When the storage period is ended, the bags are destroyed and their contents dried. The decay plant is reduced to a multi-compartment tank etc. It is easy to erect and operate. Storage times are reduced to a min.

Title: Hydrocarbon sulphonation, esp. in detergent mfr. - where density measurements at controlled temp. indicate degree of sulphonation
Inventor: KROCKENBERGER DIETER DR
IPC: C07C303/00
Filed: 1976-04-24
Abstract: Hydrocarbons are sulphonated to a desired degree between 80-99.5% by gaseous SO3. During sulphonation, a constant partial stream is continuously removed from the mixt. for degassing and adjusting to a temp. where the density is measured. The alteration is density w.r.t. time is employed to indicate the progress of sulphonation, after making an adjustment for the time lost in removing the partial stream and measuring the density. Extrapolation is used so sulphonation is stopped when the desired density is reached. The density is pref. measured at a temp. held constant to within plus or minus 0.02 degrees C. Used e.g. for the sulphonation of fatty alcohols, olefins, and alkyl benzenes in mfg. raw materials for washing agents. The process is largely automatic and can be undertaken without the need of specially trained analysts. The desired degree of sulphonation can be achieved with an accuracy unobtainable by conventional processes.
