摘要:
A light-proof transfer device makes it possible to introduce into a developer apparatus, exposed film sheets or negatives which are coiled up in a magazine. Introduction is effected automatically despite the residual curvature in the negatives issuing from the magazine. The device includes a light-tight box-shaped housing which receives the negatives on exit from the magazine, the housing containing means for pushing the negative ejected from the magazine laterally into an output slot preceded by a deflector designed to flatten out the negative which is introduced into the developer apparatus through an input slot registering with the output slot of the device, in a direction perpendicular to its own curvature.

The radiodiagnostic apparatus is composed of a radiodiagnostic table of reduced size which is easy of access for a young patient, to which table a support is attached which holds a carrier plate for the patient through the medium of mechanical devices enabling said plate to translate and rotate in relation to the table, the plate axis remaining substantially parallel to the table and the plate being provided with means to hold the patient in position.

X-ray diagnostic apparatus, particularly adapted for rectilinear tomography, comprising a column carrying the X-ray source pivoting about a horizontal axis, said column being composed of a lower and an upper parts, the latter one longitudinally displaceable relatively the former one by means of an electric motor controlled by a signal, which is a function of the angle of inclination of the column.

A syringe which may be used for storage and preservation of injection fluid includes a hollow cylindrical body which has an outlet end and an inlet end. A rupturable member is provided at the outlet end. A flange is provided at the inlet end. A sealing member, which is desirably a fluid-impermeable membrane, is fixed to the flange to seal the inlet end. A rod is provided on which a piston is connected. The piston is positionable, with respect to the cylindrical body, for entering its interior, rupturing the sealing member and moving toward its outlet end. As a result, the injection fluid stored and preserved within the hollow cylinder may be removed via the outlet end by the piston under the influence of the rod.
摘要:
Magazine for storing bare film sheets, for use in X-ray film handling apparatus, comprising a light-tight housing and a slot for introducing or ejecting said sheets, further including within said housing: a motor-driven central storage roller; a motordriven feed roller, and a plastic flexible band wound respectively around said two rollers. The film sheet introduced in the slot is wound on the central roller and stored between two faces of the band fed from the feed roller. For ejection the feed roller is driven to unwind the band from the central roller and carry the sheet towards the slot.
