Abstract: Abstract of the Disclosure Disclosed is a method for lateral (azimuth) determination with radio direction finders according to a two-channel principle, with a crossed directional-antenna system, an auxiliary antenna, and cathode-ray-tube indicator.  In a cyclically repeated three-step switching sequence, both channels of a two-channel receiver are acted upon.  In a first switching step for the purpose of balancing the brightness control and phase response, the channels are acted upon by the sum of the two direction-finder voltages of the crossed directional-antenna system.  In the second switching step, the auxiliary antenna voltage is fed to the one channel of the two-channel receiver, while the sum of the direction-finder voltages of the crossed directional-antenna system is fed to the other channel thereof, the phase difference between the output voltages from the two channels being determined and being stored as a reference for the brightness control of the cathode-ray tube.  In the third switching step, one direction-finder voltage is fed, through one channel of the two-channel receiver, to vertical deflecting plates of the cathode-ray tube, while the other direction-finder voltage is fed, through the other channel, to horizontal deflection plates of the said cathode-ray tube.  The sum of the two direction-finder voltages is used, after a phase shift in accordance with the stored reference, for azimuth-true brightening of the cathode-ray tube.  Apparatus for carrying out the method is also disclosed.

Abstract: GROWING EPITAXIAL FILMS WHEN THE MISFIT  BETWEEN FILM AND SUBSTRATE IS LARGE                        Abstract of the Disclosure A method is described for reducing the defect density in a crys-talline film grown on a substrate with which it has a substantial mis-fit.  The principle of the method is to grow the film, not directly from the substrate, but from a layer of small islands previously de-posited onto the substrate.  The technique has been fully investigated for the growth of Ag (and thence Au) films on NaCl, a substantial im-provement in the quality of the overgrown film being obtained when an intermediate layer of Ni islands is deposited on the NaCl prior to the deposition of the Ag.  It has been demonstrated that it is important for the intermediate islands to be a)   generally epitaxially aligned with the substrate, even if as a result of their misfit with the substrate, they are partially incoherent; b)   weakly bonded to the substrate so that they can move on this substrate during the deposition of the upper layer upon them; c)   approximately hemispherical and small so that elastic strains in the overgrown layer decay rapidly with distance from the island and so that the preferred adatom site density is large on the islands compared with the substrate despite a relatively low coverage of islands on the substrate of about 10%; d)   be of intermediate misfit with the substrate compared with the crystal layer to be overgrown.
