Abstract: A method produces adhesive tapes which are adhesive at least on one side, wherein an adhesive tape web, in which the at least one adhesive side is covered by a first liner, is guided into a cutting device in which a total of N individual adhesive tape strips located next to one another are produced in the machine direction from the adhesive tape web. Every other adhesive tape strip is removed from the first liner and is applied to a second liner in each case having a spacing a between the individual adhesive tape strips. The liners are cut between the adhesive tape strips located on the first liner and on the second liner, and the individual adhesive tapes, together with the liner strips, are wound up in a total of X rolls in a form of an Archimedean spiral.

Abstract: A process for the preparation of aniline by hydrogenation of nitrobenzene in the gas phase in the presence of a catalyst containing a noble metal is described. The process can be carried out in an improved manner if the catalyst employed is palladium on graphite or petrol coke, as the support, containing 0.001-1% by weight of Pd, based on the total weight of the catalyst, it being possible for the catalyst also to contain, in addition to the Pd, 0.001-0.5% by weight of Ir and/or 0.001-0.3% by weight of Rh, all figures being based on the total weight of the catalyst.

Abstract: The continuous process makes it possible to reduce the water content of polymers to minor residual levels (ppm) by adding to a W/O-emulsion an extractant which is subsequently evaporated with the oil.

Abstract: Method for the abstraction of pure serum albumin from blood which includes the steps of separating the blood plasma from the solid constituents of the blood and isolating the dissolved non-albumin constituents from plasma, adding an albumin-stabilizer and treating such fluid with a lower aliphatic alcohol, whereby, the treatment is carried out at a volume concentration of alcohol of 7 to 14% in the presence of 0.001 to 0.1 moles of the stabilizer, at a temperature of from 60.degree. to 75.degree. C. and pH of from 4.5 to 7.5; the concomitant proteins, partly or largely denatured, are precipitated; the resultant solution containing pure serum albumin is separated from the precipitate at a temperature of from 1.degree. to 30.degree. C., preferably at room temperature.
