Title: Sliding valve-stopper.
IPC: B65D47/26
Filed: 1984-01-30
Abstract: The invention relates to valve-stoppers enabling a reservoir to be filled, for it to be blocked off, and its pressure to be measured, by fitting a manometer, or for it to be emptied simply by screwing or unscrewing a machined piece by less than 1/6 of a turn. It comprises a portion B screwing into a portion A until it lightly presses on an "O"-ring 7, at which time two holes 12 and 5 are opposite each other allowing the passage of fluid from I to D. A further 1/6 of a turn and the system forms a stopper, the holes 12 and 5 no longer being opposite each other and the "O"-ring 7 forming a seal between the top A and bottom B. A hole 13 enables the fluid trapped between A and B to escape and prevents them from pressing against each other. Among the more interesting applications of the invention can be mentioned the filling and checking of suspension spheres.

Title: Objective device having variable focal length
Inventor: CORBASSON GERARD
IPC: G02B15/16
Filed: 1985-04-10
Abstract: Objective device having a variable focal length comprising, on the one hand, at least two groups of lenses which can move along the axis during the focal-length variations controlled by the operator, the final image remaining stationary during these variations for an object located at a given distance from the objective and, on the other hand, at least two other groups of lenses contributing, by means of their movement along the axis, to the focusing-distance variations independently controlled by the operator. In this objective, at least one of these focusing groups has its position determined by a law which depends on these two independent variables which are the focal length and the focusing distance, both controlled by the operator. The movements of the group in question, with respect to the final image, are smaller in absolute value than 5% of its actual focal length during the focusing-distance variations. Now, these movements have the effect of correcting certain aberrations which would appear if it were not moved during the focusing-distance variations. This objective can be used in cinematographic, photographic and television apparatuses.
