Abstract: An electronic device with densely packed components includes a bipartite housing, a film circuit guided meander-like in said housing, at least one reinforcement plate for reinforcing said film circuit over part of the length of said film circuit, means integral with at least one part of said housing for fixing said reinforcement plate in position, an illuminated display disposed in said housing for viewing said film circuit, and a calibration potentiometer disposed in said housing for contacting said film circuit.

Abstract: A mounting for display equipment, includes a lower part, an upper part, a picture screen disposed in the upper part, a connecting part rotatably supported about a vertical axis on the lower part, a support arm formed of first and second elongated hollow parts each having first and second ends, the second ends of the first and second parts being telescoped together, the first end of the first part being rotatably supported about a horizontal axis on the connecting part, the first end of the second part being rigidly connected to the upper part, at least one compensating element disposed in the support arm for pushing the first and second parts apart, the first part having at least one row of detent notches formed therein along the longitudinal direction of the support arm, at least one ratchet pawl rotatably supported about a horizontal axis in the second part, the ratchet pawl being engaged in one of the detent notches in a rest position thereof and being movable out of the detent notches in a disengaged posi

Abstract: The invention relates to an arrangement comprising a traveling-wave tube mounted in a housing, and a power supply source enclosed by a separate housing.Inventively, all electrical supply lines inside the tube housing are run to a plug mounted in this housing, projecting outward and enclosed by a sleeve of electrically conductive material. The invention further provides for a central singular electrical coupling matrix in the power source, whereby all electrical connecting lines to the traveling-wave tube are combined and connected to the outside via one electrical socket carried by this housing. Both housings can easily be mounted such that, when the plug connection is established, the plug sleeve is compressed. The invention provides a space-savingly designed unit of traveling-wave tube and current supply unit connected to each other with an HF-seal.

Abstract: An electron beam collector for transit time tubes, in particular medium power traveling wave tubes, is electrically insulated from a housing by an intermediate layer which comprises a high-voltage resistant, temperature resistant, flexible synthetic resin sheet which is metallized on both surfaces thereof. The intermediate layer, which is not closed upon itself, encloses the electron beam collector and has edge zones which project along a surface line of the collector and which extend radially outwardly, and against each other, to form a flange. The housing includes a recess which accommodates the flange, the housing including two parts which are secured together to clamp the layer between the collector and the housing in a firm clamped fit.
