Abstract
440,269. Wireless receiving-apparatus. SHEPHERD, A., The Glebe Farmhouse, Ringstead, Kings Lynn. June 26, 1934, No. 18785. [Class 40 (v)] A radio-receiver of the kind in which components make direct contact with each other has one side of the valve filament circuit constituted by a metallic chassis which serves as a screening housing. As shown in Figs. 1 and 2 two insulating strips 5 are mounted one at each end of the chassis, and on these strips is mounted a metal strip 1 which forms one side of the filament circuit ; the metallic casing 2, 4, forms the screening case and the other side of the filament circuit. The low frequency transformers 14, 15 have valve sockets mounted on their terminals and are so arranged as to constitute valve holder sockets 10, 16, 17 ; 11, 18, 19. Other components and tuning inductances are similarly arranged and connected at 9, 35, 36 ; 13, 38, 39. The H.T. supply is carried by a metal strip 56 connected to appropriate components through resistances 57 ... 60, which pass through small holes in the decoupling condenser assembly 65 ... 68. The wave range switch 69 carries contact studs 73 which engage studs 42 ... 47 through spring strips 74. Specifications 289,506, and 318,003, [both in Class 40 (v)], are referred to.
