Claims (10)

1. What we claim is : lm A device for sampling gas within the rotating bowl of a centrifuge comprising a stationary column mounted axially in the rotating bowl and adapted to carry at least one transfer tube for the sampled gas, said tube being connected to a scoop which is capable of extending transversely within a sampling chamber formed at one end of the bowl, wherein said scoop is displaceable between a with drawn position in which it is wholly contained within the column and an outwardly-extended position in which said scoop projects with respect to said column within the sampling chamber as a result of a relative displacement of said tube with respect to said column.
2. A sampling device according to claim 1, wherein the column is provided with means whereby the scoop which i connected to the transfer tube is locked in the withdrawn position..
3. A sampling device according to claim 1, wherein the scoop which forms an extension of the transfer tube at that end which inters into the bowl through the column is constituted by an elbowed portion of said tube which is disposed in a plane /substantially at right angles to the axis of the bowl and terminates in a sampling orifice, the displacement of said scoop between its outwardly-extended position and its withdrawn position being such as to correspond to a rotation of said tube about its axis through a given angle with respect to said column.
4. A sampling device according to claim $, wherein the scoop is applied in the position of outward extension with respect to the column against a stationary abutment shoulder which is integral with said column the ressur 41279/2 of application of said scoop against said abutment shoulder being produced by a torsional stress exerted on the tube in that portion thereof which is located outside the bowl.
5. A sampling device according to claim 1, wherein the column supports a series of parallel tubes each connected to a sampling scoop, said scoops being placed within each of two sampling chambers which are formed at the two ends of the rotating bowl.
6. A sampling device according to claim 2 and claim 3, wherein the ends of the tubes which are remote from the scoops are associated with a locking device which serves to lock said scoops in the outwardly-ex ended position with respect to the column, said locking device being provided with a sliding yoke which is guided along stationary rails carried by the column and adapted to cooperate with a flat portion formed in the tube, the engagement of said yoke over said flat portion being permitted when the torsional stress which is exerted on the tube and applies the scoop against its abutment shoulder attains the predetermined value.
7. A sampling device according to claim 6, wherein the torsional stress on the tube is applied by the yoke of the locking device itself, said yoke being progressively displaced under the action of a transverse screw carried by said yoke and applied against a stationary bearing member of the column.
8. A sampling device according to claim 1, wherein the scoop which forms an extension of the transfer tube at one end thereof is constituted by a bent duct disposed substantially in a plane which passes through the axis of the tube and terminates in a sam ling orifice the 41279/2 connection between said tube and said bent duct being provided by a flexible hose element, the displacement of said scoop between its outwardly-extended position and its withdrawn position being such as to correspond to a displacement of said tube in a direction parallel to the axis of the column so as to cause the sliding motion of said bent duct and said flexible hose within a curved guide passage formed within the column and having its opening on the side of said column.
9. A sampling device according to claim 2 and claim 8, wherein the tube is associated with a locking device for maintaining the scoop in the outwardly-extended position, said locking device being provided with a spacing sleeve which is coaxial with the tube and limits the axial travel of said tube with respect to the column and with a cross-bar or the like which cooperates with a slot formed at the end of said tube.
10. A sampling device according to claim 1, substantially as hereinbefore described with reference to and as illustrated in the accompanying drawings. For the Applicants DR. R£INH0LD COHN AND PARTNERS
