Abstract
641,227. Wave-guides. WESTERN ELECTRIC CO., Inc. Dec. 23, 1946, Nos. 37768 and 37769. Convention dates, Jan. 11, [Class 40 (viii)] A phase-shifting device for a wave-guide comprises a short guide section containing a dielectric plate, either fixed and extending across the guide from side to side as shown at 1 in Fig. 1A, or rotatable about an axis parallel to the axis of the guide as shown in Fig. 6. The strip can be rendered practically reflectionless by suitably placed reactance screws or by cutting it to a point or fish-tail at its ends. In the adjustable construction shown in Fig. 6 an iris diaphragm 19 is provided to cancel reflections and the strip is rotated by control means 20. Specifications 591,369, 597,258 and 617,381 are referred to.
