Abstract
A scale modelling centrifuge has a relatively massive rotary circular base wall, which may form part of a drum, possibly with a detachable peripheral wall either carrying an annular sample-receiving trough or constituted by such trough, or which may have mounted therearound a plurality of sample-receiving containers.
Claims33
A centrifuge comprising a central region in said centrifuge, a substantially horizontal rotary wall having a substantially vertical axis, a central portion of said wall in said central region, an annular outer periphery of said wall concentric with said axis, said wall being rotatable about said axis, means mounting said wall for rotation about said axis, a work support located in said central region, and rotary receiving means supported by said wall, located in a region of said outer periphery and accessible from said work support, and stationary means relative to which said wall and said receiving means are rotatable.
A centrifuge comprising a substantially horizontal rotary wall having an annular outer periphery concentric with an axis, said wall being rotatable about said axis, rotary receiving means supported by said wall and located in a region of said outer periphery, and access-permitting means in said wall permitting access from below by an operator.
A centrifuge including a rotary member rotatable about an axis and provided with an annular recess substantially co-axial with said axis and opening towards said axis, a sample carried by said rotary member radially outwardly of said recess, a stationary conduit for supplying liquid to said recess, and duct means extending from said recess towards said sample for conducting said liquid under centrifugal force from said recess towards said sample.
A centrifuging method, comprising providing a centrifuge including a rotary wall having an annular outer periphery concentric with an axis and rotary receiving means supported by said wall and located in a region of said outer periphery, introducing a model into said receiving means and rotating said wall and said receiving means about said axis to subject said model to centrifugal force, and shaking said model.
A method of controlling hydraulic pressure, comprising providing liquid in a container having an interior, rotating said container about an axis, operating drive means to displace selectively in one of a direction of increasing hydraulic pressure in said container, which direction is substantially radially outward of said axis, and a direction substantially radially inward of said axis;
- an outlet end of duct means communicating with a region of the interior of said container at which the hydraulic pressure is exerted.
