Abstract: A connector assembly comprises a mounting portion for mounting the connector to a complementary portion which could be either another connector or a member fixed to a structure such as an automobile's bodywork. The mounting portions comprise interengaging T-shaped walls and T-shaped profiles that are longitudinally slidably interengaged. The mounting portion walls comprise interleaving recesses and extensions and that enable the mounting portions to be interengaged by placing the mounting portions one against each other and then sliding them in opposing directions by only a short travel. The latter enables longitudinally slidable T-profiles to be used but nevertheless over short travel which is advantageous for certain applications to reduce cable length surplus.

Abstract: A primary-beam collimator for a stereo radiographic x-ray diagnostic installation has an x-ray tube with dual focal points (F1, F2) arranged at a distance from each other. Shutter leaves (1a, 1b, 2a, 2b, 3a, 3b, 4a, 4b) are provided, and adjustable so that two beam pyramids (I from focal point F1, and II from focal point F2) can be individually controlled. Two internal shutter leaves (4a, 4b) are provided for restricting the beam in planes perpendicular to the stereo base F1-F2. These are adjustable between two external shutter leaves--each in the direction of its corresponding external shutter leaf. The internal shutter leaves (4a, 4b) are constructed so that, when adjusted to their external positions, they permit the emission of a central beam-pyramid from a central focal point (FN) and, together with the external shutter leaves (2a, 2b), they close the external shutter openings.

Abstract: In the illustrated embodiment, a single counterweight suspended on a traction cable compensates a plurality of differently moving apparatus parts and is of significantly lesser weight than corresponds to the sum of weights of the compensated apparatus parts. The cable is shown as coupled with the sighting device beneath the patient's support as well as with the carrier column for the X-ray tube while yet being operable to simultaneously compensate the torque of the carrier column in different orientations of the patient support, including a vertical disposition.

Abstract: In the illustrated embodiments, a pair of primary X-ray diaphragm plates have cooperating front edges each with angled sections forming a generally V-shaped edge configuration and providing an included aperture angle facing the symmetry axis, of from 50.degree. to 150.degree., the angled sections being connected by a definitely rounded central section for conforming to rounded boundary contours of different organs such as the heart. The diaphragm plates are advantageously oppositely inclined and crossed so as to be capable of assuming a symmetrical overlapping relation in defining small diaphragm apertures. Further the diaphragm plate front edges may exhibit progressively reduced absorption values to provide a penumbra effect about the freely transmitted cone of rays particularly so as to facilitate examination of marginal zones of an organ which is surrounded by regions of greatly reduced absorption value.
