Abstract: 415,784. Directive wireless signalling. LORENZ AKT.-GES., C., 1, Lorenzweg, Tempelhof, Berlin. March 3, 1933, No. 6465. Convention date, Nov. 29, 1932. [Class 40 (v).] Relates to a wireless system for assisting an aviator to land, of the kind in which a clubshaped bundle of waves are radiated upwards from the aerodrome and the pilot descends upon a curve of constant field intensity, for instance along one of the curves 1-5, Fig. 1. According to the invention, means are provided to enable the navigator to make a less steep descent by cutting across the curves along the line B, 6, 7, 8, 9, 10. This result is achieved by progressively decreasing the effective sensitivity of a field-intensity indicator of the type described in Specification 404,167, and then steering the aeroplane so as to keep the indicator at a constant reading. The required progressive decrease in sensitivity is obtained by gradually inserting resistance, through a suitable clockwork mechanism, into the circuit of the indicator. The clockwork may be automatically brought into operation when a certain field-strength is reached, or by cooperation with an auxiliary beacon station of the type described in Specification 406,144. Alternatively, the indicator scale of the measuring-device is progressively moved to vary the effecting sensitivity.
