Abstract: ABSTRACT:        A tunable magnetron comprising a rotatable tuning body for producing a rapid variation of the tuning frequency of the magnetron. This rapid tuning variation is combined with a slow or quasi-stationary tuning variation produced by a second axially displaceable tuning body having conductive parts, which project into the resonance cavities from the opposite end of the said cavities as that, from which the first rotatable tuning body projects into the cavities. By an axial displacement of the second tuning body the whole tuning range caused by the first tuning body can be shifted along the frequency scale.

Abstract: PREPARATION OF TETRAALKYLTHIURAM DISULFIDES                 ABSTRACT OF THE DISCLOSURE    A tetraalkylthiuram disulfide is prepared in a higher yield without formation of by-products by subjecting the corresponding alkali metal dialkyldithiocarbamate to electrolytic oxidation, which is carried out in a two-layer electrolytic medium consisting essentially of either (1) water and carbon disulfide or (2) water and a mixture of carbon disulfide and a halogenated alkane of higher density than water, the carbon disulfide being predominant in the mixture, by means of electrodes placed in the aqueous layer containing the dialkyldithio-carbamate.  The resulting disulfide is extracted to the lower layer of the electrolytic medium and is recovered from the layer.  The dialkyldithiocarbamate can be continuously produced in situ by adding carbon disulfide and dialkylamine gradually to the aqueous layer of the electrolytic medium, which contains an alkalimetal hydroxide produced during the electrolytic oxidation of the dialkyldithiocarbamate.
