The input shaft supports a lever for transmitting the movement of the input shaft to a pinion fixedly connected to the lever. The pinion rolls along an internal toothing and supports an engaging member which is in slidable engagement with a switch arm connected to the switch drive shaft.

Abstract: An antenna matrix switch bay includes a housing which is subdivided in a plurality of chambers defining a matrix configuration of coaxial transmitter switches and coaxial antenna switches provided with opposing fixed contacts in row direction and column direction. Each chamber of the housing contains one single switch whereby one transmitter switch and one antenna switch define a node and have a common switch drive shaft perpendicular to both planes. The switch drive includes a straight switch member in each plane and a double-cranked switch member insulated from the switch members and connecting the fixed contacts of one plane with those of the other plane.

Abstract: A sealed cable connector includes a plug or coupler with a sleeve extending over the cable end and surrounding a strain relief ring, contoured annular seal and a thrust collar. The seal includes an outer ring and an inner ring which are connected with each other by a radial bridge. During assembly, the thrust collar and the strain relief ring cooperate with each other in such a manner that upon axial displacement of the thrust collar toward the strain relief ring by means of a screw plug turned into the sleeve, the bridge becomes sheared off thereby compressing the inner and outer rings within the respective inner and outer spaces between the thrust collar and the strain relief ring while at the same time the thrust collar presses the outer cable conductor against a contacting face of the sleeve.

Abstract: A coaxial-line connector includes a jack having an outer conductor and an inner conductor part divided in at least two segments and arranged in said outer conductor. Clamped in the inner conductor part defining the jack is an inner conductor part forming the plug. At least one pressing screw is arranged in a radial bore of the outer conductor to exert a radial clamping force on the segments to attain a reliable and tension-proof connection between the inner conductor parts. The setscrew is accessible so as to allow an adjustment of the clamping force.

Abstract: A waveguide device for producing absorption or attenuation includes a waveguide section which is provided with an external absorber material. For allowing a transfer of the high-frequency power into the absorber material, the wave section is provided with coupling apertures via which the absorber material is in connection with the interior of the waveguide section.

Abstract: A coaxial-line section includes an outer conductor and an inner conductor tube centered coaxially inside the outer conductor and contacted by couplings which are supported by insulators or beads. The couplings are provided at their facing ends with a ring of laminated springs which allow the thermal expansion of the inner conductor tube. Extending inside along the inner conductor tube are two preferably bar-shaped displacement compensating elements. The axial inner end of each displacement compensating element is firmly anchored to the inner conductor tube while its axial outer free end defines with the end faces of the respective coupling a stop face.

Abstract: A cooled waveguide assembly includes a plurality of extruded waveguides connected to each other via their respective flanged portion. Each waveguide has an outer profile corresponding to the outer dimensions of the flange portion which is created by suitably fabricating the end sections of each waveguide. The flange portion is provided with a plurality of boreholes which are in alignment with pockets to allow fasteners to be inserted therein so as to connect adjoining waveguides. Integrated in the wall of each waveguide are cooling channels which are arranged in such a manner that they do not intersect with the boreholes. The cooling channels and the interior of the waveguides are sealed at the respective joints by a profiled sealing element.

Abstract: A waveguide usable as absorber or as attenuator for high radio-frequency powers up to highest frequencies includes a tube with a dissipative material at whose inside a metallized layer is applied. The thickness of the metallized layer changes along the length of the tube with its initial thickness and end thickness determined in such a manner that a constant power density is obtained along the waveguide.

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: A 3dB waveguide directional coupler for coupling two rectangular waveguides of the same dimensions and having parallel longitudinal axes is disclosed. The waveguides to be coupled are joined so that one of the wider side walls of the first waveguide adjoins one of the wider side walls of the second waveguide. The interiors of the two waveguides communicate via an aperture in the adjoining side walls. When energy is input from one end of the first waveguide toward the aperture, virtually all of it is transmitted to the second wave guide, part of the transmitted energy traveling away from the aperture in each direction along the longitudinal axis of the second waveguide. This is preferably achieved by providing a waveguide system in the aperture oriented perpendicular to the longitudinal axes of the first and second waveguides.

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: 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: An outer sleeve with connector socket are slipped onto the bared end of a coaxial cable whereby a clamping sleeve with axial slot and conical head is spread radially. The clamping sleeve is resiliently biased so that its head engages a tapered control surface in the outer sleeve tending to clamp the clamping sleeve against the cable end. Frictional engagement of the cable end reinforces that clamping action. The head may either grip the bared outer conductor or an insulation jacket on the cable. The rear portion of the clamping sleeve makes electric contact with the outer conductor of the cable and has contact fingers for making sliding connection with the socket.
