Abstract

438,804. Directive wireless signalling. LORENZ AKT.-GES., C., 1, Lorenzweg, Tempelhof, Berlin. May 24, 1934, No. 15541. Convention date, July 24, 1933. Addition to 405,727. [Class 40 (v)] The parent Specification relates to a transmitting arrangement for course determination comprising a continuously energized dipole aerial associated with reflecting dipoles which are alternately keyed to obtain two sets of complementary signals in different directions to define a course on which both are received at equal signal strength. In the present invention this transmitting arrangement B is elevated above the ground so that lines of constant signal strength 1 ... 5 slope down to an aerodrome F and an aircraft flying on the equi-signal strength course above defined can follow a line of constant signal strength to the landing ground. An additional signal from a vertically directed transmitter 9 or from another horizontal beacon indicates when the landing is to be commenced.
