In a facility for checking large-volume goods, in particular freight goods, with an X-ray source, which emits X-rays for irradiating the goods, and with a detector arrangement aligned with the X-ray source, the detectors of the detector arrangement are designed or arranged in such a way that detector rows are produced with two row limbs which abut one another at right angles on their longitudinal sides, of which one limb is aligned parallel to the movement direction of the goods being checked, and the other is aligned perpendicular to this in the direction of the X-ray source.

To depict test objects using electromagnetic waves, particularly to check people for suspicious articles, an apparatus is provided having: an antenna which emits electromagnetic waves, particularly millimetric waves, means for concentrating the emitted waves in three dimensions, and means for manipulating the waves at the point of high concentration such that this point serves as a moving virtual antenna for SAR evaluation. Whereby the means for three-dimensional concentration contain a rotatably mounted, focusing or defocusing, quasi-optical element and the means for manipulating the waves at the point of high concentration contain a reflector. In accordance with the invention, the quasi-optical element and the reflector are rotatably mounted about a common rotary axis and at the same angular velocity.

For assembling/disassembling a printed circuit board, a specially shaped spring is to be integrated inside the device. The assembly/disassembly of the printed circuit board in the device is simplified by virtue of the fact that the printed circuit board has to be pressed only against the spring and a fixed supporting part of the device to which the spring is attached. In order to be able to press the printed circuit board, among other things, perpendicularly against the fixed supporting part, the specially designed leg spring is fastened underneath the fixed supporting part. The legs of this spring protrude outward on both sides beyond the top-side of the supporting part. During assembly, the printed circuit board is guided between the top-side and the protruding spring legs. The printed circuit board is fixed by additional supporting parts of the device.

Ignition circuit for a gas discharge lamp. In the ignition circuit, the generating of uniform current pulses for ignition over the entire useful life of the gas discharge lamp is guaranteed. A control circuit is provided for holding constant the current-time integral of current pulses applied to the gas discharge lamp during ignition.

A device for triggering a thyristor uses light pulses or flashes for achieving a galvanic separation between the triggering circuitry and the load circuit. The light pulses are generated by a flashlamp disposed in a housing in which a number of channels extend radially, each channel having a light conductor therein. The light conductors lead to respective individual thyristors which are to be triggered.
