1. A machine comprising, in combination:
- a machine rotor,a housing for said rotor,a base frame formed from section beams (11, 11'"'"',
25).fastening means (14,
15) detachably connecting said machine to said beams andseparating joints (16, 17, 27, 27'"'"',
28) between said fastening means (14,
15) and said section beams (11, 11'"'"',
25), said separating joints and said section beams in the region of said fastening means being filled with material strong in compression and capable of deadening structure-borne noise,said fastening means being at least partially embedded in said structure-borne noise deadening material.

Abstract
In the fastening of noise-generating machines, particularly centrifuges, the noise in the form of structure-borne noise is often transmitted to other parts of the plant. In order to largely to prevent this, separating joints (16, 17) filled with structure-borne noise deadening material are placed between the fastening parts (14, 15) and the section beams (11, 11'"'"') to which the centrifuge with its housing is fastened.

6. A machine comprising, in combination:
-
a machine rotor, a housing for said rotor a base frame formed from section beams (25,) of box section, fastening means (24, 24'"'"') connecting said machine to said beams and separating joints (27, 27'"'"',
28) between said fastening means (24, 24'"'"') and said section beams (25), said separating joints and said section beams in the region of said fastening means being filled with a material strong in compression and capable of deadening structure-borne noisesaid fastening means (24, 24'"'"') partially enveloping said box shaped section beams (25) over substantially the length of said machine housing (26).

-
a machine rotor, a housing for said rotor, a base frame formed from section beams (11, 11'"'"',
25),fastening means detachably connecting said machine to said beams and separating joints (16, 17, 27, 27'"'"',
28) between said fastening means and said section beams (11, 11'"'"',
25),said separating joints and said section beams in the region of said fastening means being filled with a structure-borne noise deadening material in the form of concrete whereby structural borne noise transmitted by said machine to said section beams by way of said fastening means passes through said concrete.
