Abstract: A device for connecting coaxial cables includes an inner bridging member rigidly connecting the inner conductors of the cables to be linked. The outer conductors of the cable are connected by a metal sleeve which resiliently surrounds and contacts both outer conductors and is clamped in circumferential direction. The sleeve is divided in distinct sections whereby those sections surrounding the conductors to be connected are provided with webs extending radially inwardly so as to provide the resilience of the sleeve.

Abstract: A radio frequency coaxial switch includes a movable contact piece and at least one stationary contact roll which is supported at one end portion of a leaf spring. The other end of the leaf spring is connected to an inner conductor of an associated coaxial connection. The leaf spring prestresses the contact roll in direction of the movable contact piece so as to guarantee a secure contact between these parts.

Abstract: A coaxial short-circuit device has an inner conductor which is surrounded by an outer conductor and is electrically connected to the latter by a shorting plunger. In order to allow the axial movement of the shorting plunger, the inner conductor accommodates a spindle which is connected in a force-locking manner to a first carriage arranged between the spindle and the inner conductor. A second carriage is arranged between the inner and the outer conductor and cooperates with the first carriage in such a manner that upon rotational movement of the spindle the first carriage is axially shifted along the spindle and this movement is transmitted to the second carriage and eventually to the shorting plunger which is connected to the second carriage in a force-locking manner.

Abstract: For the transmission of a plurality of light channels between two parts which rotate relative to each other, an optical transmission element is arranged with its optical axis OA coaxial to the axis of rotation and light transmitters in different radial regions. By convex lenses or mirrors the bundles of rays coming from the light transmitters are parallelized and impinge on the optical transmission element which individually focuses the bundles of rays. In order to obtain an imaging scale of 1:1 a synchronously rotating rhomboid prism or a parabolic mirror can be used. In addition, HF channels can be transmitted.

Abstract: A plug inner conductor for connection to a tubular inner conductor of a coaxial cable is disclosed. The plug inner conductor includes a spreading sleeve having a slot formed therein which permits the effective diameter of the sleeve to be increased. A clamping cone is inserted through the spreading sleeve and has a shape which will cause the clamping cone to place a radially outward force on the spreading sleeve as the clamping cone is moved axially through the spreading sleeve. The clamping cone is coupled to an inner conductor sleeve in such a manner that the clamping cone is moved axially with respect to the inner conductor sleeve as the inner conductor sleeve is rotated.

Abstract: For a rectangular waveguide the wall thickness of the narrow sides b of the rectangle is smaller than the wall thickness of the broad sides a of the rectangle with the ratio of the wall thicknesses being so chosen that approximately the same resistance to deformation is obtained in both directions. For waveguides which consist of welded plates the broad sheet metal plates 10 are cut to the nominal inner dimension and the sheet metal plates which form the narrow sides and have a lower wall thickness abut laterally against the two plates belonging to the a side.

Abstract: The present invention relates to a coaxial high frequency plug connector which consists of a coupler and a plug in which the coupler is provided with external screw threads and bayonet paths which intersect the screw threads and the plug is provided with either corresponding internal threads or corresponding interlocking bayonet projections for the bayonet paths. By this means, alternate methods of connection may be utilized using the screw thread portions for interengagement by screw threading and using the bayonet projections and bayonet paths for interengagement by bayonet type mounting.

Abstract: A connector for a coaxial cable having a dielectric and an outer conductor supported by the dielectric comprises a bushing that can be emplaced between the dielectric and the outer conductor, a tension member that acts radially inward upon the outer conductor so that mechanical contact is made between the outer conductor and the outer surface of the bushing. The bushing has at least one axial slot. A cut leading edge of the outer conductor is inserted through the slot from the inner surface of the bushing after the bushing is placed over the outer conductor. The bushing and slot are configured so that the outer conductor passes through the slot and wraps around the bushing upon relative rotation of the bushing and the coaxial cable.

Abstract: A directional coupler for coupling between four inner conductors 16,18,20,22 of four coaxial lines has two coupling conductors 10,12 which are connected across respective pairs of inner conductors 20,22,16,18, and are spaced apart to define a coupling gap 14. The width of the coupling gap can be varied by tilting movement of one, and preferably both coupling conductors which are attached to the respective inner conductors by tilting joints in the form of leaf springs 124. A modification (FIGS. 4,5) enables the coupler to be used for crossed coaxial lines.

Abstract: The disclosure concerns a detachable coupling for a pressure-medium-filled high frequency line and/or for a coaxial line and/or for a hollow wave guide. The abutting ends of two sections of the line are gas sealed. A valve arrangement at the abutting ends opens the communication between the line ends when the line sections are coupled and seals the line sections when the line sections are separated. Various valving arrangements are illustrated for various types of lines, coaxial lines and wave guides.

Abstract: A coupling device for coupling a jack connector and a plug connector is disclosed. One connector is externally threaded and the second is provided with an internally threaded cap nut. A cap ring is mounted on the cap nut so that rotation of the ring rotates the cap nut in the same direction. A first ring of axially pointed rigid teeth is provided around the circumference of the cap ring or on a separate sleeve. The first connector has another ring with at least one rigid axially mounted tube for engaging the first tooth ring. For connection the cap nut is screwed onto the first connector. The teeth are shaped to pass over each other easily as the cap is screwed on. To facilitate connection the cap ring is withdrawn axially, against the force of a biasing spring, while the cap nut is screwed on. Then the cap ring is released and the spring urges it into locking engagement with the other tooth ring.

Abstract: The disclosure concerns an HF attenuator for a hollow waveguide or a coaxial conductor. A rod of dissipative ceramic material is disposed along the length of the attenuator, so that moving along the length of the attenuator, the ceramic material increasingly defines or replaces at least one wall of the hollow waveguide or at least one of the two opposite sides of the coaxial conductor. A coolant passage may be provided along the rods of ceramic material. The ceramic material may take other forms, such as leaves and annular rings. In another embodiment for use in a waveguide, at least one wall of the longitudinal opening through the waveguide is defined by ceramic leaves, whose extent of projection into the opening is varied for HF attenuation.

Abstract: Transmission line apparatus for transmitting TE dominant electromagnetic waves is provided in accordance with the teachings of the present invention. The transmission line apparatus according to the present invention relies upon a transmission waveguide having a uniform cross-section which is substantially larger in dimension than that required for propagation of only the TE dominant electromagnetic wave desired to be transmitted. The transmission waveguide is in fact so large with respect to the transmission frequency for the TE dominant electromagnetic wave selected that a plurality of waves can form and be propagated, however, losses along the waveguide are markedly reduced. The transmission waveguide is provided with guides in the form of structure present in the waveguide which prevents a rotation of the plane of polarization of the TE dominant electromagnetic waves being transmitted.

Abstract: The invention relates to an HF terminating impedance in strip conductor technique in which the resistive layer is enclosed between two ceramic plates which are clamped from the outside by metallic heat dissipating plates, the freedom from reflection of the terminating impedance being ensured by the lateral edge lines of the resistive layer satisfying the condition ##EQU1## To ensure an intimate heat conduction contact between the resistive layer and the ceramic plates and the ceramic plates and the adjoining clamping plate without introducing bending stresses into the ceramic plates which might cause fracture, at the contact surfaces a soft metal foil, preferably of lead, is inserted which is prevented from cold flow by a rolled-in grating or netting, in particular of bronze or copper.

Abstract: A rotary coupler of the non-contact type has folded resonant spaces when seen in radial section. A large central lead aperture may be provided.

Abstract: Method and circuit arrangement for protecting coaxial cable in transmission equipment: at the input and at the output of the cable, a proportional fraction of the high frequency energy is coupled out; the coupled out high frequency energies are compared and there is disconnection when the comparison shows a particular value.

Abstract: A clamping device for securing HF fittings to coaxial cables or hollow conductors by means of a clamping sleeve surrounding the cable outer sheath or the hollow conductor sheath. The sheath is radially inwardly deformed by the clamping sleeve in such a manner that a transformation is effected which guarantees a reflection-free transition to the adjoining fitting. In the end portion of the cable or hollow conductor the outer sheath is engaged radially so that it is compressed, giving a reliable hold. The cable sheath is thus deformed in a definite manner so that at the point of entry into the fitting it has a predetermined size, said deformation gradually or abruptly decreasing towards the cable in a transformation portion. This deformation can be effected by suitable means, for example axial tensioning or by a two-part clamping sleeve with tangential tensioning.
