摘要： In a circulator using strip technology a high thermal conductivity through the piled up parts is obtained by use of heat conductive insulating grease layers between the parts which include a solid machined metal cap surrounding the gyromagnetic pellets and broad banding circuits between the ports and earthed contacts on the strip substrate, the capacitor of which uses said cap as an electrode. The outside of said cap is cylindrical, the inside hexagonal.

摘要： Quick release interconnection of waveguide circuits terminated at least partially by a standard flange is achieved by rotation of a clamping ring which surrounds the first circuit termination and cooperates by means of outer grips with a groove in a base mounted on the second circuit. Tight engagement is obtained by means of protruding pins carried by a sleeve fastened to the first circuit guided by semicircular cams and locked in a recess in inclined spring guides carried by the inner face of the rotatable ring. Disengagement is obtained by rotating the ring counterwise. Fool proof interconnection is obtained by a unique means protruding from the standard flange and registering with a unique recess in said base.

摘要： In a surface wave isolator consisting of two gyromagnetic slabs a conductive strip between said slabs, means to establish a magnetizing field within said slabs, a two part load is associated side by side with said slabs and the strip extends also between the two parts of the load. A first part of the load is a continuous load parallel to the strip, a second part of the load is a plurality of localized absorbing means placed along the propagation axis and parallel to said strip. The impedance of the localized absorbing means is matched to the impedance of an unwanted parasitic propagation mode at the corresponding place.

摘要： A transmission cable using optical fibre for conveying the information consists of fibres loosely laid in helical grooves of a core so that the fibre will undulate within the groove due to over-length given by pretwisting of the fibre and curvature of the groove flanks. Reduction of the contact surface between the fibre and the core improves the electrical characteristics and reduces the sensitivity of the cable to mechanical stress.
