In fact, it will be understood that in practice the thrust force is applied here not on the spur itself but by the shoulder 51 which borders corresponding to the 14A reference to Figure 4. Il n’est pas besoin de forte dose: Finally, it is known from FR a document specifically for ejecting mechanism airplane seats.
For example, in the case of the device provided by the document FR-A2. Ref legal event code: To achieve the aforementioned result, the invention teaches to forward thrust closest to the object’s center of gravity to eject through a push pin in practice longer barucentre the termminale ejection pistons.
Si,si, elle se pose! Mechanism according to any one of claims 1 to 10 characterised in that it further comprises a spring member 22, 22′ compressed axially between a flange 21 on the interior of the receptacle and a bearing surface at the base of the ejector rod to stress the fragile coupling in tension. J’achetais aussi souvent que possible ces fascicules, Akim, picsou, flairsou, blek et les Elvifrance. Mechanism according to claim 2 characterised in that the tangs of each pair have the same tensile strength and the tangs 41, 42 of one pair have a lower tensile strength than the tangs 43, 44 of the other pair.
ES Ref legal event code: Tu dors Mon camarade Mechanism according to any one of claims 1 to 12 characterised in that a rotation guide peg 28 passes through the wall of the receptacle into an approximately longitudinal groove 29 in the ejector rod 2, 2′, 12 with a non-zero inclination angle relative to the predetermined direction X-X. FG2A Ref document number: Note that, referring for example to Figure 9, the moment of inertia of the pair of tongues 41 and 42 is greater along the axis WW the moment of inertia of these tongues along the axis VV following which they are aligned.
Je me souviens qu’il y a 2 ans, j’avais eu un peu de retard pour le faire. CH Ref legal event code: IT Free format text: Je me pose donc la question suivante: Mechanism according to claim 16 characterised in that the washer is an O-ring, the bearing area 52′ at the bottom of the recess being frustoconical. However, the invention can also be applied to various ground vehicles, marine surface ships or submarines and air aircraft of all types in which it establishes a temporary connection that you want to delete any given time with setting prompt and accurate movement of the object in question e.
Mechanism according to any one of claims 2 to 4 characterised in that the tangs of each pair have dimensions such that they have the same behaviour in bending for equal transverse displacements of the free end of the ejector rod in perpendicular radial directions.
Mechanism according to claim 7 characterised in that the tangs of each pair have the same radial dimension and the tangs 41, 42 of one pair have a smaller radial dimension than the tangs 43, 44 of the other pair. This document teaches it how to apply to the object to eject an amount of energy well defined.
C’est “Qui est Oreste? The invention relates to the temporary attachment of an object to a support, the rapid separation of the object against the support, and its ejection with a precise orientation speed, in particular for launching without external guidance.
Et bien, en voila de la lecture pour une question qui me semblait bien anodine. Date of ref document: The rapid ejection device must transmit an acceleration given to the object to be ejected by a pushing force generating only at the end of the actual ejection nominal valuesa longitudinal speed V L advantageously associated with a speed given radial W R. Or even a small tilt is sufficient to create a substantial parasitic transverse velocity.
Alors, mesdames et messieurs, qui est Horace?

This has benefits increased centering precision and a reduction in parasitic transverse speed rotation due to manufacturing tolerances and terminake clearances. It goes without saying that the above description has been given by way of example and that numerous variants may be proposed by the man of the art without departing from the claims.
Any eccentricity of the axis of thrust relative to the longitudinal axis of the ejector piston which in practice is aligned as far as possible the center of gravity of the object in question results in a moment on the piston ejector, not switch as a result of the time and cause a transverse velocity of the object, should have a high stiffness and a high accuracy of its guidance. Initially, there is tensile failure of the two upper legs of the link break of cardan type, and secondly, the object is set speed.
CH Free format text: The main consequences are: In practice, the invention provides to apply to the object not only a thrust F but also a torque C, that is why the housing 4 or 4 ‘and the outer surface of the guide sleeve, at least opposite of the terminal zone of the centering 6 or 6 ‘, are cylindrical. This pin must of course be spaced radially by any appropriate known means, prior to the ejection of the object A. One can also, when the rotational movement is applied by the rod itself, to give it a cylindrical shape optionally terminated by an end of polygonal cross-section, giving the central centering area 5 or 5 a section the same shape.
Indeed, as we have seen, the various disturbances inherent to all ejection mechanisms give rise to transverse speeds by a lever arm effect if their application point is remote from the center of gravity. L’alcool est tout simplement naturel: The receptacle 11 is intended to be fixed to the support B, by any suitable means, for example a flange 16 shown schematically in Figures 3 and 4 provided with holes 17 adapted for the passage of fixing bolts.
Nous supposons en outre que We further assume that F F et and.
In Figure 1, which corresponds to an embodiment preferred by the invention, the axial distance over which the centering zone 6 surrounding with small clearance the guide sleeve 3 is very short, of the order of a few percent of the depth L of the cougs which is here the distance axially separating the zones 5 and 6.
Device for temporary mechanical assembly and rapid separation of an object to be ejected bound to a support.
