    摘要： A convex ink meniscus is obtained at the outlet of the nozzle by hydrostatic pressure created by a pump situated between the ink reservoir and the nozzle. The ink jet is obtained by an electric field. The pump is of the continuous type, means being provided to reduce the operational pressure at the level of the nozzle from the value necessary to create a convex meniscus to a value for which the ink remains substantially contained inside the nozzle. A control device acts on these means to render them inoperative and ensures the re-establishment of the meniscusforming pressure at the beginning of each period of writing. The pump may have a member having a surface of revolution in which a spiral passage is hollowed, a second member with a second surface of revolution is applied against the first and movable by electromagnetic means.

    摘要： A system for uniformizing the speed at which a kinematographic film is wound round the take-up spool in a view-taking or projecting apparatus by means of a feeler engaging a loop formed by the film between the exposure gate and said spool. When ever the speed of winding excessively tensions the film passing out of the gate, the loop shrinks and the stops the spool either by opening a switch in the circuit feeding a driving motor or by mechanically acting on a roller or gear driving the spool For reversed progression a second roller or gear can be used which is similarly controlled by the feeler.

    摘要： A rangefinder comprises a projector furnishing a modulated light beam directed on to the object to be ranged and a receiver to pick up the reflected rays. The rangefinder is designed to avoid disturbances of the readings by chance interference signals. The receiver has a photoelectric cell at the front and rear of a mirror on to which some of the reflected rays are converged by a lens. The photocells are mounted for axial displacement so as to adjust for equal light reception according to the convergence and hence the range of the rays reflected from the object. The signals from the photocells are cut off and connected by a device actuated in rhythm to conform to a constant phase relationship with the light beam modulation. The cut off device connects the receiver to a storage device for the measured signals in which the stored sums of the interfering signals give a substantially nil value. The storage device is an RC element whose time constant is several times that of the beam modulation. The circuit includes a differential amplifier. Output signals from ''''gate'''' circuits control the axial displacements of the photocells by supplying a motor driving a threaded shaft bearing a tapped nut supporting the photocells. A camera incorporating the rangefinder has an objective adjustment ring coupled to respond to rotation of the shaft.

    摘要： An objective chiefly for kinematographic cameras adapted to compensate for untimely shifting of the objective when the camera is held by hand during operation. This compensation is provided by resorting solely to the precession of one or more gyroscopes adapted to rock around an axis with reference to a cage pivotally carried by the objective mount around an axis perpendicular to the axis of the gyroscope, said cage being urged by a spring into a predetermined position and connected with a pivotal optic element incorporated with the objective in a manner such that any angular movement of the cage produced by the precession of the gyroscope causes the pivoting optic element to be shifted with reference to the objective mount to an extent such as will compensate any sudden modification in the angular setting of the optical axis of the objective.

    摘要： The system is adapted to grasp the end of the outer convolution of a wound film, tape or the like strip. To this end it resorts to one or preferably two movable, spaced-apart members such as belts or pulleys engaging the periphery of the wound strip so that the relative difference in speed between the two members at their portions engaging said periphery urges the strip passing across the gap between the two members into said gap to form a slight bulge. When the end of the outer convolution reaches a position facing said gap, it passes over the bulge and is urged outwardly through the gap and away from the grasping system.

    摘要： In a cinematographic camera a shutter, formed by a sector with parallel faces, is interposable between an objective and a film, and is arranged to reflect rays over all its blanking zone to a photosensitive element. Means are provided for lowering the light flux transmission towards the photosensitive element in the normal rest position of the shutter.
