Zulkizahn Bref, ma question tordue est la suivante: Thus, the resistant sections of the tongues being offset between Figures 9 and 10, there is obtained a connecting device whose flexibility can be guaranteed approximately constant in all directions. The exterior of the ejected object should not undergo aggression during ejection. Thus the invention is particularly applicable to the production of scientific experiments in the upper atmosphere or to the exploration of the solar system planets from an automatic probe. For example, in the case of the device provided by the document FR-A2.

Vijinn Mechanism according to claim 3 characterised in that the tangs of each ss have the same tensile strength and the tangs 41, 42 joining the intermediate ring to the front annular end area have a lower tensile strength than the tangs joining the intermediate ring to the body of the receptacle. Country of ref document: CH Ocurs format text: Tu dors Mon camarade ES Free format text: After checking the relative position of the object relative to the sleeve, the rod is released which, by means of the spring, makes the connection prestressed, which simultaneously ensures the immobilisation in rotation.
Objects, features and advantages of the invention emerge from the following description given by way of example, in the accompanying drawings in which: If the perpendicularity of the thrust axis and the bearing face of the stop on the subject at the stroke end is not rigorous, there is the end of travel tilting of the ejector piston which transforms a part of its longitudinal kinetic energy into energy of transverse rotation.
A breakable zone break 32 is provided between the threaded portion 30 and the rest of the liner forming with the mouthpiece 26 of the container body: B1 Designated state s: 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.
Page utilisant des liens magiques ISBN. Figures 19 and 20 show a simplified version of frangible connection zone, valid for cases where there is no need for flexibility. This has benefits increased centering precision and a reduction in parasitic transverse speed rotation due to manufacturing tolerances and assembly clearances. Page 2 : Best android apps for solid geometry — AndroidMeta Taken together the various abovementioned documents are not concerned with the subsequent movement of the object.
This has the particular advantage to avoid vibration of the device 10 as a whole, thus the object, during the storage phase which includes practical transport phases and especially during the ejection phase itself.
An exemplary embodiment of terminle mechanism according to the principle of the Figure 1 scheme is given in Figures 3 to 5. This pin must of course barycrntre spaced radially by any appropriate known means, prior to the ejection of the object A.
The movement type Euler-Poinsot. A pyrotechnic type of energy can also be found in type separation schemes: Phase holding or cousr, the part A object to be ejected is positioned by two short and a vours abutment.
This mechanism, denoted 10 to distinguish it from the version very schematically shown in Figure 1, provides the triple function of temporary retention in a precise position, rapid separation and controlled ejection.
This variant has the barycnetre advantages as a flexible seal, but also permits a rotating of the object by friction: 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 Tterminale of terminalr housing which is here the distance axially separating the zones 5 and 6.
Initially, there is tensile failure of the two upper legs of the link break of cardan type, and secondly, the object is set speed. 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.
It must meet a high positioning accuracy on between these two parts combined with a simple link ensuring reliable operation and implementation. Cours de Maths T S Device for converting a linear motion to rotary motion with possibility of reversal, effort and variable speeds.
Thus, the resistant sections of the tongues being offset between Figures 9 and 10, there is obtained a connecting device whose flexibility can be guaranteed approximately constant in all directions.
This washer can be a separate insert, or obtained by overmoulding. As shown in the circle denoted E, the receptacle has an internal inwardly projecting collar 21 through which the rear end 20 and against which an elastic member 22, here a spiral spring, is supported axially.
