Abstract
Abstract A centrifuge particularly for use for sugar extraction includes an outer protective jacket which is supported on a gimbal ring for resilient pivotal movement. The ring, in turn, is supported on resilient pivots for pivotal movement about an axis extending 90* to the pivotal mounting of the jacket. The centrifuge includes a drum mounted within the jacket for rotative movement. In one embodiment the drum is supported by and driven by an electric motor which in turn is carried on radially extending arms supported on the outer protective jacket. In another embodiment the driving motor is mounted on a stationary frame and the drum is driven by a telescopic drive shaft connected to the motor and to the respective drum through pivotal or universal joint constructions.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
136 words
A centrifuge comprising a fixed support, a horizontally arranged gimbal ring, means pivotally and resiliently supporting said ring on said fixed support for rotation about a first axis extending diametrically across said ring, said resilient means include a plurality of spring elements having a spring travel greater in the horizontal direction than in the vertical direction, a vertically extending cylindrically shaped protective centrifuge cover located within said ring, second pivot means carried on said ring and in engagement with said protective cover for pivotally supporting said cover for pivotal movement about a second axis spaced angularly in the plane of said ring at 90* from said first axis, a drum located within said protective cover, meanS mounting said drum wthin said cover for rotation therewithin, and drive means connected to said drum to rotate said drum.

A centrifuge comprising a fixed support, a horizontally arranged gimbal ring, means pivotally and resiliently supporting said ring on said fixed support for rotation about a first axis extending diametrically across said ring, said resilient means include a plurality of spring elements having a spring travel greater in the horizontal direction than in the vertical direction, a vertically extending cylindrically shaped protective centrifuge cover located within said ring, second pivot means carried on said ring and in engagement with said protective cover for pivotally supporting said cover for pivotal movement about a second axis spaced angularly in the plane of said ring at 90* from said first axis, a drum located within said protective cover, meanS mounting said drum wthin said cover for rotation therewithin, and drive means connected to said drum to rotate said drum.
Claim 3
Dependent Claim
52 words
A centrifuge according to claim 1 characterized in that said means for rotating said drum comprising a driving motor, means mounting said driving motor in a fixed location adjacent said drum, and pivotal and extensible shaft means connected between said motor and said drum for rotating said drum within said gimbal suspension.
Claim 4
Dependent Claim
22 words

Claim 6
Dependent Claim
48 words
A centrifuge according to claim 1 wherein said drive means comprises a fixed motor, means on said cover extending centrally therewithin and rotatably supporting said drum, and shaft means having pivotal and extensible portions connected to said fixed drive motor and to said drum for rotating said drum.
Claim 7
Dependent Claim
28 words
A centrifuge according to claim 1, characterized in that the suspension of the centrifuge in said gimbal ring is located about the center of gravity of the centrifuge.
