Abstract: An antenna assembly for mounting an antenna on a vehicle body, especially upon the roof of a vehicle, in which the assembly has a base body of metal with a threaded projection passing through a hole in a wall of the vehicle body. A housing of plastic encloses the antenna components mounted upon a plate-shaped portion of the base body and a seal is provided between the base body and the vehicle body and seals around the opening between the base body and the wall of the vehicle. The seal can be injection molded and molded onto the base body in the injection-molding process.

Abstract: Process for mobile reception of television signals in which an output signal (SA) is derived from n different (S1 . . . S5) and is supplied to the reproduction part of the receiver, the n input signals (S1 . . . S5) being weighted, the output signal (SA) being formed by summing of the weighted input signals, and the quality of each of the n input signals (S1 . . . S5) being evaluated using at least one given criterion for determining the adaptively determined weighting factors, characterized in that the n input signals (S1 . . . S5) are time-synchronized before their evaluation, summing and weighting, and the horizontal and/or vertical video synchronization pulses contained in the input signals (S1 . . . S5) are used for control of time synchronization.

Abstract: An antenna assembly for a motor vehicle and especially for an antenna structure on a window of such vehicle in which a support plate is provided between an antenna amplifier and the antenna structure and has at least one but preferably a plurality of spring contacts locked through openings in the support plate and having arcuate portions respectively engageable with contact points on the antenna amplifier and contact pads of the antenna structure.

Abstract: An adapter for making contact between an antenna structure on a window pane of an automotive vehicle and the antenna signal processing unit which can be positioned at an optional location thereon as plug connectors for flexible leads running to the signal processing window and contact elements which are yieldable and bear against the conductive pads of the antenna structure. The adapter can be mounted at any optional location on the vehicle body.

Abstract: A connector has a front insulating body, a contact fixed in the main body and having rear-end parts forming an axially open seat adapted to receive a conductor of a stripped wire and radially displaceable toward each other, and structure radially compressing the parts toward each other to grip the conductor. This structure is an intermediate body formed with an axially tapered passage fitting over the rear-end parts and axially displaceable to displace the rear-end parts radially toward one another.

Abstract: A plug for a coaxial connector and cable, especially an antenna plug, in which the outer conductive sleeve is formed entirely or partly of metal by punching, stamping, cutting or the like from sheet metal and is then bent into the sleeve shape, provided around an insulator and contact pin and held around that insulator by plastic deformation.

Abstract: A coupler for a coaxial plug and connectable with a cable, especially an antenna coupler with an outer conductive sleeve comprised entirely or partly of metal and formed by bending from a blank whose basic shape is produced by stamping or punching from steel metal.

Abstract: An antenna assembly for a motor vehicle has a housing mounted on the vehicle body and overhanging a portion of a window provided with an antenna connector structure. A carrier removably mounted on that housing has one or more contact elements which bear directly against a printed circuit board in the housing and carrying the antenna signal processing circuitry and against the antenna conductor structure on the window.

Abstract: An electric appliance (1) comprising modules (2, 3) that can be juxtaposed to one another and interconnected using bridge elements (4) for transmitting electric signals and operating voltages. The modules (2, 3) and bridge elements (4) are provided with a pair of plug-in connectors (31) and also a pair of mating plug-in connectors (25, 26). The plug-in connectors (31) are each mounted in a cylindrical outer sleeve (36), and the mating plug-in connectors (25, 26) are mounted in cylindrical ducts or penetrations (19). An O-shaped sealing ring or gasket (38) is arranged about the circumference of each outer sleeve (36), so that the O-shaped gaskets (38) are under pressure when the outer sleeves (36) are inserted in the penetration (19) to interconnect the plug-in connectors (31) and the mating plug-in connectors (25, 26).
